This one-off magazine celebrates the coming together of scientific excellence and development relevance. The pursuit of these two ideals is what makes research highly exciting and deeply rewarding. It also brings fundamental and applied research closer together and advances knowledge sharing across disciplines, and between researchers, policy makers and practitioners. F Reuters / Jianan Yu 4 | Synergy undamental research is often contrasted with socially relevant, or applied, research. The first is thought to be conceived high up in the purported ivory towers of universities and measured by academic rigour, ingenuity and originality. The second is thought to be a derivative of this enlightened activity – with both feet firmly on the ground applied research aims to contribute to solving real-life problems such as poverty, illness and the impact of environmental degradation on people’s livelihoods. In other words, so goes the belief, fundamental research aims to expand and deepen our body of academic knowledge, while applied research is interested in doing so only when it serves a clear social purpose. The two are thought to take place in parallel universes. But they do not. This magazine seeks to enhance understanding of the relationship between development relevance and fundamental research. There are many who believe that science should not be burdened with considerations about social relevance, that such considerations would detract from the pursuit of excellence and result in mediocre science. Others feel strongly that free scientific inquiry is seldom relevant to policy makers and practitioners in the field of international cooperation, and that only applied research can contribute to solving global challenges. Taken together, these ideas boil down to the belief that scientific excellence is limited to fundamental research and that relevance can be found only in applied research. Such a belief is based on misconceptions. At heart there is no such tension between the excellence and relevance of research. Highquality validated knowledge is a crucial prerequisite for development relevance, and a precondition for realizing equity, social justice and environmental and economic sustainability. The flipside of the coin is that development and other global challenges can be a source of inspiration for scientific inquiry and lead to fundamental queries and scientific paradigm shifts. Definitions of fundamental research often indicate that such research is curiosity-driven and that it usually takes a long time before its outcomes find an application. This characterization, however, misses the central point that fundamental research is carried out to increase understanding of basic principles. Its purposes are to develop new paradigms for theory building and to push the frontiers of theoretical understanding within existing paradigms. There is, however, no reason to assume that such fundamental research cannot be inspired by social problems. Nor does a focus on fundamental principles necessarily imply that the outcomes need to go through a lengthy process of elaboration and translation before they can be applied. To mention but a single example, the groundbreaking ideas of the Nobel Prize laureate, economist Amartya Sen, have fundamentally shifted our understanding of development and given rise to a wave of theory building. His thinking has inspired development-oriented policy makers and provided the underlying conceptual framework for the UNDP Human Development Index. Definitions of applied research commonly focus on the actual practice of solving problems and addressing social needs. This overlooks the fact that applied research is, first and foremost, research. Applied research is an interactive inquiry process that balances problem solving with academic analysis to understand underlying causes. A fundamental understanding of such causes is precisely what is needed to tackle urgent problems. There is no reason why research into underlying causes could not evolve into Fortunately many researchers do. This magazine provides a wide range of examples of research that is academically outstanding and at the same time provides knowledge that is crucial for addressing global challenges effectively. Sometimes this research was designed to find solutions to practical problems, and came to be recognized by academic peers as an excellent contribution to science. Other examples show research that was intended to answer fundamental academic questions also addressing – directly or indirectly – the challenges in today’s globalized world. The projects featured in this magazine were selected through a call for proposals by Testaments to the successful coupling of scientific excellence and social relevance theory building or spark off fundamental questions. For example, the Dutch ecologist Marten Scheffer has been researching the social and ecological drivers of ecosystem change that affect fish stocks in Lake Victoria. One aspect of the research was to model the interactions and feedbacks resulting from eutrophication (an increased concentration of nutrients) and commercial fishing. His work on the ecosystems of lakes has fed into his work on the mathematical modelling of complex systems. For this he received the Spinoza Prize, the highest Dutch award for outstanding scientific achievement, often referred to as the Dutch Nobel Prize. Opportunities for enhancing the synergy of fundamental research and social relevance are growing. Development discourse is widening. It embraces emerging topics of global concern, such as climate change, resource depletion, global health and migration. These concerns call for – and offer exciting opportunities for – interdisciplinary research that addresses interrelated causes and raises fundamental questions. Global development challenges can inspire any scientist, regardless of their theoretical backgrouds or how fundamental the scope of their interest is. The question is: who seizes this challenge? Hivos and the MDG Profs. In addition to highlighting a number of life-enhancing research projects, this magazine also features interviews and short essays – all of which are testaments to the successful coupling of scientific excellence and social relevance. With this publication, we hope to inspire scientists from different disciplines and to open up the dialogue between scientists, policymakers and practitioners of international cooperation – who undoubtedly all share the ambition to excel in creative problem solving. ■ Henk Molenaar, executive director WOTRO Science for Global Development.

Synergy | 5 PROJECT Fighting tuberculosis in Indonesia No ‘quick-fix’ research More than two billion people worldwide are infected with the tuberculosis bacterium. And in developing countries, it is a major killer. Infectious diseases specialist Reinout van Crevel is passionate about finding better ways of diagnosing and treating this life-threatening infection. I PRIOR The Medical Centre at Radboud University Nijmegen collaborates with universities in the Netherlands, Indonesia and Tanzania through the virtual research centre PRIOR (Poverty Related Infection Oriented Research). Infectious diseases are a major cause of health problems in developing countries and form an obstacle to economic development. The complexity of these problems requires a multidisciplinary approach. The PRIOR partners combine expertise in molecular biology, immunology, parasitology, nutritional sciences, internal medicine, pharmacology, epidemiology, public health and psychology. 6 | Synergy nfectious disease is a major cause of death and health problems right across Africa and Asia. Some diseases, such as malaria and HIV/Aids are well-publicized killers. But it is not always realized that tuberculosis (TB) alone causes the deaths of two million people each year. Indonesia has the third-highest number of TB patients. When Reinout van Crevel of the Radboud University Nijmegen Medical Centre travelled to Jakarta in 1998, he was struck by the lack of proper diagnostic techniques and TB treatment plans. He swapped the laboratory at Nijmegen University for hands-on research in Jakarta, and began a commitment that has lasted more than twelve years. The urban slum clinic that Van Crevel visited in the late 1990s was overstretched, treating more TB patients than all the hospitals and clinics in the Netherlands. And the emergence of HIV as a major public health problem in Indonesia in the mid2000s exacerbated the problem further. HIV patients are susceptible to TB infection and many ultimately die of it. ‘In the Netherlands, research institutes would immediately try to get on top of such a situation,’ says Reinout van Crevel. ‘But in Indonesia, an academic response is almost entirely lacking.’ Effective treatment starts with effective diagnosis. And more than 125 years after the Mycobacterium tuberculosis was first discovered, microscopy is still the best, and the simplest, way of diagnosing pulmonary TB. However, bacteria must be present in high concentrations in a patient’s sputum sample in order to be detected. In areas where HIV is prevalent, this is a problem because HIV patients usually have a low bacterial burden. New diagnostic techniques currently being developed are costly, and therefore difficult to implement in poor countries. So Van Crevel and his Indonesian colleague, Bachti Alisjahbana decided to tackle the problem in a different way. Instead of developing new diagnostic techniques, they decided to optimize the volume and quality of patients’ sputum samples. They designed a larger sample container and instructed clinicians in the best ways of explaining to patients how to collect an optimum sample. Using these two very basic approaches, the number of TB patients being accurately detected doubled. Van Crevel and Alisjahbana wrote about their findings in The Lancet.1 Van Crevel believes that basic research and applied research are a necessary pair. ‘I would not want one without the other,’ he says. This inter-reliance can be seen in a research Reuters / Andrew Wong programme on HIV and drug use that was set up in Bandung, West-Java in 2007. This programme resulted in earlier diagnoses, and much lower mortality rates, in HIV patients. It also produced a biobank of the DNA and blood samples of more than 1500 patients. The biobank is now an extremely valuable resource for basic research – not least for Van Crevel’s own study on genetic susceptibility to tuberculosis. Patients with advanced HIV-infection are extremely susceptible because of the loss of a particular white blood cell, the ‘CD4-positive T-cell’. Yet data from the Bandung biobank show that, some patients with virtually no CD4 cells left do not develop TB in this endemic setting. Van Crevel believes that ‘good genes’ are behind this, and hopes to identify the mechanisms that make it happen. An important spin-off from the TB research is the contribution it made to local capacity building. Since it began, three doctors from Indonesia have been awarded PhD degrees in Nijmegen. They are now published authors, who are strongly committed to their home universities. ‘We are trying hard to help make the local academic infrastructure attractive enough for them to stay on as researchers after completing their PhDs,’ explains Van Crevel. ‘Unfortunately, promising research career opportunities are few in Indonesia.’ The tragedy of scientific research, according to Van Crevel, is the perpetual peaking and troughing of funding. He advocates consistent and substantial core funding for collaborative centres of excellence, such as the one at Padjadjaran University in Bandung, co-founded by the PRIOR virtual research centre. One of the key values of PRIOR is longterm collaboration and mutual commitment. ‘Quick-fix research solves nothing,’ says Van Crevel. ‘We focus on a few institutes with which we have been collaborating for ten to 30 years.’ In the context of supporting longterm relationships, Van Crevel emphasizes the importance of equality between academic partners as well as the goal of serving the local agenda. ‘Certainly, we like our research to have an immediate impact on the quality of care, but our academic partners in countries such as Indonesia should have the same opportunities as us to delve into fundamental scientific questions. It would be patronizing to suggest that they should limit their academic pursuits to the day-to-day issues that plague their health systems.’ Van Crevel believes that there are good strategic reasons why his Indonesian colleagues should tackle fundamental scientific research. ‘While their operational research might have relevance in other low-resource settings, their answers to fundamental research questions are just as relevant in London or New York as they are in Jakarta. This year, one of our PhD students published a paper in Lancet Infectious Diseases on the underlying mechanisms responsible for the ‘success’ of a particular strain of TB.2 Through this, she became part of a global research network. This will bring her closer to the funding she needs to carry out further research into this TB strain.’ Van Crevel is convinced that, wherever science is taken seriously, integrating fundamental and operational research will bring advantages. ‘It ensures that researchers from different backgrounds are obliged to explain and justify their hypotheses and methods. This makes for better and more relevant research – as well as better clinicians and more rounded university teachers.’ ■ Alisjahbana, B. and van Crevel, R.

Synergy | 7 INTERVIEW Can pure mathematics halt desertification? Menno Bijleveld Arjen Doelman, director of the Lorentz Centre and professor of applied analysis at the Mathematical Institute, Leiden University, is looking for ways to predict desertification using fundamental mathematics to analyze vegetation patterns. Mathematician Arjen Doelman recently started a research project along with ecologist Max Rietkerk from Utrecht University. The project aims to develop early warning mechanisms for desertification by analyzing vegetation patterns – and it exemplifies the interplay between pure science and practical relevance. In his office at Leiden University, Doelman talks about the project and its mathematical foundations. Arjen Doelman Arjen Doelman received his PhD from Utrecht University, worked at Cornell University and as assistant professor at the Department of Mathematics in Utrecht. Between 2004 and 2009, he worked at the Centre for Mathematics and Computer Science (CWI). In 2009, he was appointed professor of applied analysis at the Mathematical Institute of Leiden University, and director of the Lorentz Centre, an international centre that coordinates and hosts workshops in the sciences. 8 | Synergy Professor Doelman, what is mathematically challenging about vegetation patterns? For me, pattern formation is one of the most fascinating fields in mathematics. And that is what this project involves, viewing vegetation patterns through a mathematical lens.1 We are still only beginning to comprehend pattern formation. Understanding turbulence, which is one of the most complex patterns one can imagine because it is chaotic in both time and space, presents one of the biggest challenges for mathematicians and physicists today. Werner Heisenberg, a 20th century German theoretical physicist, is reputed to have said that he expected God to be able to explain the theory of relativity, but not the theory of turbulence. You have referred to the prediction of the English mathematician, Alan Turing, that there will never be a truly embracing nonlinear theory of pattern formation. Do you agree with him? I think he might be right, but the challenge is to get as close as possible. The LandauTuring ‘weakly nonlinear stability theory’, asserts that the appearance of periodic, or rhythmic, patterns can be explained. But we are getting closer to a more comprehensive theory of pattern formation. This has been helped by the development of more powerful computers that allow us to run extensive simulations using enormous amounts of data. Further development of mathematical insights into pattern formation is absolutely crucial if we want to get closer to a comprehensive theory. How does your own work contribute to the development of a more comprehensive theory? I have a special interest in patterns that emerge from ‘perfect’ periodic patterns, such as defect patterns. Fingerprints are a good example. Each fingerprint is unique because of the defects in its perfect pattern – it is periodic, but with errors. Such patterns cannot be described with the Landau-Turing theory. So we are hoping to develop a new theory, which would form a significant new component of Turing’s theory. An essential part of understanding why and how patterns lose their periodicity is to understand how they react to changing parameters. This is right at the core of our project on vegetation patterns – Max Rietkerk and I want to know how changing circumstances affect vegetation patterns. Can you explain the relationship between the mathematics of pattern formation and desertification? On the borders of deserts you will see all types of vegetation patterns. A pattern can, for example, consist of long strips of vegetation alternated with strips of sand. This is called tiger bush. Such a vegetation pattern might be only marginally stable, and will destabilize if certain parameters – such as rainfall or grazing intensity – reach a critical point. You could call this a threshold or a tipping point. Often, exceeding the threshold will cause the vegetation system to collapse altogether. This is because the desert – which is an extremely stable state – acts like a vacuum cleaner. When a vegetation system destabilizes because of external factors, the desert will seize the opportunity and suck it in. Desertification is not a gradual process, it resembles a catastrophe. And when the system has crossed its tipping point, it is virtually impossible for it to return to its previous state. Based on the mathematical characteristics of such Understanding turbulence is one of the biggest challenges for mathematicians marginally stable patterns, Max and I believe that we can distil indicators that tell us how close a vegetation pattern is to collapsing. Does that mean you expect to be able to predict desertification by looking at the features of a vegetation pattern? Yes. The ultimate aim of our project is to develop early-warning signals for desertification that can be determined by measuring certain characteristics of the vegetation pattern. We suspect that the distribution of the sizes of the vegetation patches will be an important indicator. A rather simplified example of this is that when the vegetation patches are all roughly the same size, it could indicate a stable system, while an area with both large and small patches could indicate that the system is close to its tipping point. patterns pose fundamental mathematical questions. Addressing these questions allows us to continuously develop new pieces of mathematics. And working with scientists from other disciplines spurs us to think differently. Every time I speak to Max he asks me questions that I would have never come up with myself. These questions often yield novel and ‘pure’ mathematical insights. Reality feeds into, and inspires mathematics. A project like ours truly cuts both ways. ■ Arjen Doelman was interviewed by Koen Kusters Some examples of academic articles by Arjen 1 Doelman on pattern formation: •Doelman, A., Sandstede, B., Scheel, A., Schneider, G.

Eritrean and Dutch researchers joined hands to find out what it tells about prevalent linguistic theories. Their research also aims to contribute to improving literacy education in this African country. I Sjaak Kroon 10 | Synergy n 1991, after thirty years of war, Eritrea gained independence from Ethiopia. The political leaders’ new motto was ‘unity through diversity’. And to ensure adherence to this multicultural principle, they decreed that primary school children in Eritrea would be taught in the country’s nine different languages, using three scripts – Ge’ez, Latin and Arabic. Twenty years later, political reality has tempered post-war enthusiasm, but Eritrea’s school children are still growing up multilingual. They are instructed in their mother tongue, taught Tigrinya and/or Arabic, and learn English as well from the age of six or seven. So, quite young Eritrean children have to read and write three languages using two or three different scripts. The rugged language landscape in Eritrea provides a unique opportunity to test one of the major psycholinguistic theories about how children acquire literacy. This scientific challenge was taken on by Eritrean doctoral student, Yonas Mesfun Asfaha, as part of his PhD thesis. He was supervised by Dr Jeanne Kurvers, an associate professor of Humanities at Tilburg University, and Professor Sjaak Kroon, head of the Department of Culture Studies, School of Humanities, also at Tilburg. The central aim of the project was to compare beginners’ reading and writing skills in the different scripts. The research was carried out in schools right across the country. The main question asked was whether learning to read in a script in which symbols represent syllables is easier than learning to read in an alphabetic script where symbols represent sounds (phonemes). Investigating this question in Eritrea is interesting from a practical as well as a theoretical perspective. The country’s three scripts represent different language units: Ge’ez is based on syllables, Latin is based on phonemes and Arabic script is based on a consonantal alphabet – and all are taught as part of one national curriculum. One clear finding was that learning a syllable-based script (Ge’ez) is initially easier for children than learning a phonemebased Latin script. This proved to be the case despite having more basic units. For example, Tigrinya, which uses a Ge’ez script, has 245 symbols; languages such as Bilin use a modern Latin alphabet of 26 phonemes. Interestingly, syllabic teaching of the Latin script in the Saho language produced better reading results than alphabetic teaching of the same script. This finding breaks new ground in the psycholinguistic ‘grain size’ theory, which advises the use of small unit (phoneme-based) teaching for early reading instead of large unit (syllable-based) teaching. This landmark finding resulted in a peer-reviewed publication in Applied Psycholinguistics.1 Yonas Mesfun Asfaha emphasizes that his research also had a strong sociological side to it – making it all the more exciting. In the peer-reviewed Journal of Sociolinguistics, he and his colleagues argue that, in order for language policies in multilingual and multiscriptal countries to be successful, it is essential that policy makers have a thorough understanding of attitudes to literacy and people’s preferences for particular scripts.2 Yet while there is a wealth of research into literacy practices in multilingual communities, studies that address attitudes to literacy and scripts are still rare. To investigate such attitudes, Asfaha and a team of research assistants conducted structured interviews with a wide cross-section of Eritrean adults. They also carried out a survey of 670 respondents from the country’s nine ethno-linguistic groups. The findings showed that literacy was valued very highly and was associated with personal enrichment, independence and higher self-esteem. These were valued slightly above economic benefits and better job prospects. Fortunately, the members of the Language Panels at the Ministry of Education, who are responsible for designing Eritrea’s school curricula, showed genuine interest in the research and its outcome. Asfaha was invited to comment on the ongoing development of the middle-school language curriculum. In addition to his teaching job at Asmara University, he currently serves as a consultant in the preparation of complementary elementary education teaching materials. With his all-round commitment, Kurvers and Kroon at Tilburg University say that Asfaha fitted in seamlessly with their research group at Tilburg University. There, staff members share a strong academic curiosity about the relationship between language and society, and a personal dedication to putting their research to use. ■ Asfaha, Y.M., Kurvers, J. and Kroon, S. (2009) 1 In many ways, this research was an evaluation of Eritrea’s language policy. It showed that more than 75% approved of the policy. But, as Asfaha explains, ‘in a country where literacy is highly valued as a ticket to social mobility, some parents of minority language communities are not keen at all on the mother-tongue educational policy. For instance, for the 20% or so of Eritrean children educated in the Latin script, it is discouraging that the languages that use this script are rarely used outside school. Interestingly, as many as 23% of the respondents wished the government to change the scripts in which their languages are written. This can sometimes be for religious reasons. Some Muslims would prefer their language to be written in Arabic script rather than Ge’ez or Latin.’ The science behind Asfaha’s research fed into the project’s practical goal – to improve the delivery of basic literacy education in Eritrea through evidence-based recommendations to policy makers, curriculum developers, teachers and teacher trainers. In Eritrea, as in many sub-Saharan countries, it is unlikely that the Millennium Development Goal of achieving universal primary education will be achieved by 2015. And yet, it has long been known that a country’s literacy rates are strongly linked to its development and gross domestic product.

(2008) 2 Literacy and script attitudes in multilingual Eritrea. Journal of Sociolinguistics 12 (2), 223-240. Tangible ethics Inspired by a wish to give something back to their research communities, Asfaha and his team collected a selection of Eritrea’s oral histories known in the Tigre language and wrote them down in illustrated reading primers. These booklets were given to all schools where subjects were taught through the Tigre language. While parents in Eritrea are outspoken about the value of literacy and have high ambitions for their children, the sad fact is that in much of rural Eritrea, books and other reading matter are hard to come by. As a result, many children run the risk of falling back into illiteracy after finishing primary school. Synergy | 11 INTERVIEW We depend on insects Menno Bijleveld Marcel Dicke, professor of entomology at Wageningen University, studies interactions between insects and plants. A molecular and behavioural ecologist, his work is highly multidisciplinary and bridges the gap between theory and practice. He is well known for his efforts to encourage a greater appreciation of insects and for advocating a peaceful co-existence between people and ‘bugs’. What is so interesting about insects? Theory and practice Marcel Dicke has received national and international fame for his original scientific publications – in e.g. Nature and Science – as well as his review articles and lectures. Several of his publications (now totalling almost 300) belong to the best-cited articles of the journals concerned. The fundamental insights of Dicke’s academic work are valuable for plant breeding and biological control and his research has contributed to reductions in the use of pesticides in agriculture and horticulture. 12 | Synergy Insects are important for people. The global demand for animal protein is growing spectacularly because of the changing dietary requirements of a rapidly increasing human population. Producing meat requires large expanses of land for the cultivation of animal fodder crops. But agricultural land is limited, and we must learn to use it wisely. That is where insects come in. Ten kilograms of grass produces one kilogram of beef, but the same ten kilograms of grass can yield nine kilograms of grasshopper meat. In other words, the conversion of plants to animal protein is much more efficient through insects. Moreover, it is possible to breed insects using waste material, which makes it even more efficient. If we really want a sustainable future, we need to start eating more insects – which are already considered delicacies in many countries. But that is not the only reason why they are important for us. Insects control plant- eating pests and are therefore crucial for sustainable agriculture. Can you explain what your research is about? I study the interaction between insects and plants. My particular focus is on the way plants communicate through emitting scents, or what we call ‘volatile chemicals’. When a plant is attacked by a plant-eating insect, it produces a scent that attracts the enemy of its attacker – an insect-eating insect. You could say it sends out an SOS. It is a very clever, indirect defence mechanism. The plants ‘know’ that their enemy’s enemy is their friend. What drew you to study the scents of plants? My research questions are always spawned by my interest in fundamental questions. I want to know how things work. My personal curiosity drives my research. Does that mean that practical relevance is not an important consideration when you formulate your research questions? I like to compare science with art. Both are essential to our way of life and our civilization. Whether a particular academic research project is useful to society should not be the main driver of research. Fundamental science is crucial. And applied science depends on fundamental knowledge. We should realize though that even when a research question is guided by fundamental science, ideas about its application are never far off for creative scientists. My discipline, entomology, is very close to practice, and research outcomes tend to be applicable. How is your research on plant–insect interaction applicable? Within a plant species, cucumbers, for example, plants respond differently to insect attacks. Some send out their SOS message ‘louder’ than others, which means that they are less vulnerable to pests. This is valuable knowledge for growers. If you can identify the loud screamers, you can select them for breeding. This way, they can breed plants that are most effective at attracting natural allies whenever they are attacked. Plant breeders are starting to become more interested as they realize that this reduces the need for pesticides. However, they are asking for quick ways of distinguishing between the quiet and the louder plants. This is what we are working on now. Is this finding relevant to developing countries? Sustainable protection of crops is needed everywhere. In developing countries, agriculture tends to be small-scale and Perhaps I am a maverick within the academic community – I attach a great deal of value to telling my story to a larger audience many of the farmers cannot afford chemical pesticides. This makes biological pest control all the more important for them. Also, nearly all agriculture in developing countries is out in the open. This means that insects are a permanent threat. But in open environments, using pesticides is hazardous because you run the risk of inadvertently killing the pest’s natural enemy as well. Biological pest control is therefore the most effective and the safest method in the long run. You have been praised for making your research accessible, even appealing, to a wider audience. Why do you do this? Personally, even if the issue of applicability does not steer my research questions, I enjoy making my research accessible outside the academic community. It is rewarding to discover practical applications, for example in the field of plant breeding and pest control, but it is also a pleasure to share my enthusiasm with the general public. Perhaps I am a maverick within the academic community. I attach a great deal of value to telling my story to a larger audience. I want to encourage people to start looking differently at insects – they are not dirty and useless. We are conditioned to think of insects as nuisances that we should get rid of, but killing insects creates all sorts of problems. I make a plea for greater appreciation of insects and for peaceful coexistence between people and insects. That is my message: human life on earth depends on insects. This was also the central theme of a week-long festival we organized, called Wageningen, City of Insects. We showed people how insects are intertwined with human life. More than 20,000 visitors turned up. It was a huge success. And the media coverage was overwhelming. Virtually all the Dutch newspapers reported on the event, and Reuters produced a film that has been sold in 40 countries. This is a wonderful way of sharing academic insights with the rest of society. The week ended with a world record in insect eating: 1750 people simultaneously ate dishes of mealworms. Unfortunately, even after this success, it is still hard work to convince my academic colleagues that organizing events like this is good fun. What academic incentives are there for helping your research to reach a wider audience? None really. There are few incentives to publish outside the academic system. We Synergy | 13 INTERVIEW HH / Evan Sung If we really want a sustainable future, we need to start eating more insects – which are already considered delicacies in many countries Pioneer Marcel Dicke was awarded the NWO Spinoza Prize in 2007. He made his first groundbreaking discovery in 1986. At that time it was already known that plants could defend themselves against herbivorous insects by releasing toxins. Dicke demonstrated that plants can also release ‘scents’ that attract predatory mites, which in turn attack the herbivorous mites. This pioneering work opened up a new research area on tritrophic interactions – interactions between plants, herbivorous insects and predatory insects. In 1988 he was the first to publish in this new field of ecology. 14 | Synergy are primarily evaluated on the basis of our publications in high-impact, peer-reviewed journals. What do you think of the increased emphasis on excellence? I am not against it. One should always exploit one’s talents and want to be the best. When students ask for my advice on finding a job, I tell them to look for something they really enjoy doing, and then strive to become the best in that field. Some, however, think salary is more important, an attitude that can be spotted from afar. And what do you think about the way excellence is measured? We first need to ask ourselves: what is excellence? Publishing in high-impact journals is rewarding in scientific terms as well as for the publicity it generates, but I find that merely focusing on high-impact journals is too one sided. It reduces science to a game of ratings and numbers. And it is not always useful to focus on journals with the highest impact factor. For some of our work, it makes much more sense to publish in lower-impact journals targeted at specific audiences such as plant breeders or agronomists. In fact, some of my most cited publications are in lower-impact journals. So you need to identify who you want to reach before choosing your outlet. Excellence, at the end of the day, also implies being able to make science understandable to society. ■ Marcel Dicke was interviewed by Koen Kusters COLUMN Internationalizing courts makes fairer societies I n his seminal work, The Idea of Justice, Nobel Prize laureate Amartya Sen hails democracy as the way to tackle injustice. But he is also sceptical about how effective current institutional arrangements are in guaranteeing political and human rights. It is true that merely establishing courts will not eliminate corruption or make trials fair. But improving judicial systems remains indispensible to creating fairer societies, not least in developing countries. My research focuses on how courts and judicial systems are, or are not, influenced by legal practices from abroad. Judges increasingly look to international and foreign law when deciding difficult cases, and to strengthen the authority of their judgments. As part of a pioneering stream of research, I study the extent to which judges, when deciding cases, take into account the experiences and decisions of judges working in other jurisdictions. Consistent application of the law across jurisdictions has the potential to increase the legitimacy of judicial practices everywhere. Jeremy Waldron, professor of law and philosophy at New York University, argues that ‘we have a responsibility, rooted in fairness, to play our part in the creation and sustenance of a body of consistent law ... that transcends national legal systems as humanity transcends national legal systems.’ Developing countries and young democracies are likely to benefit from the internationalization of their judiciaries. Judges may more easily come to solid, wellreasoned judgments when they examine the practices and judgments of counterparts in other democracies. And if the courts in developing countries make comparative references to the case law of respected foreign courts, this can strengthen the authority of their judgments in the eyes of the public. The South African constitution states, ‘when interpreting the Bill of Rights, a court, tribunal or forum ... must consider international law, and may consider foreign law.’ But this is not without its risks. Transplanting arguments from, say, German case law, is tricky if a lawyer is unfamiliar with German law. An incorrect use of comparative law will then hinder rather than reinforce the legitimacy of judicial decisions. Using comparative law Consistent application of the law across jurisdictions can increase the legitimacy of judicial practices everywhere requires a sound methodological approach. My research on the methodology of judges aims to help them to develop new visions and strategies. Legal tradition and language and the prestige of foreign courts influence the selection and application of foreign case law. On that basis, I am elaborating a more systematized approach to using international and foreign law in judgements. Developing countries can benefit from this research through the guidelines it offers for the creation of judiciaries that are able to use inspiration from foreign courts in the interests of their national citizens. ■ Elaine Mak is associate professor of jurisprudence at Erasmus University, Rotterdam. In 2008, she was awarded the Research Prize for her work on the influence that globalization has on legal systems. Here, she reflects on the insights her work provides for understanding and improving the functioning of judiciaries in developing countries. Synergy | 15 FEATURE Knowledge for global development Anyone who still believes that academic excellence is the preserve of fundamental scientific research, and that socially relevant science belongs on a lower academic plane, is in for an intellectual reality check. However, judging science in terms of its relevance remains a tricky issue. 16 | Synergy H H / Tibor Bognar FEATURE T The Broker Too often, there is little interaction between research, policy and practice in the field of global development. The Broker, a bimonthly magazine and web platform, features analyses of cutting-edge academic debates that bridge this gap and contribute to policy making in areas such as economics, security, environment, governance and technology. See: www.thebrokeronline.eu 18 | Synergy Reuters / Stringer Shanghai oday’s world is beset by major challenges – widespread poverty and inequality, conflict, food insecurity, epidemics, the loss of biodiversity, climate change and the depletion of fossil fuel sources. Most of these problems affect us all, but it is the poorest countries that bear a disproportionate share of the burden. Dealing with such complex, and often interrelated, phenomena requires all the intellectual might of innovative researchers – not just those who work in development studies, but all scientists, from mathematicians and biochemists to linguists and medical scientists can make a contribution. While many scientists are motivated by the desire to improve the world we live in, they are also driven by everyday concerns such as institutional incentives and personal ambition. Tenure track systems have been introduced at many universities in the Netherlands, with the result that academic prowess is increasingly measured in terms of publication in peer-reviewed journals. These journals are judged on their citation index – the more often a journal is cited internationally, the better it is for the contributing authors, and their academic careers. Awarding points for acceptance by quality scientific journals is one of the main ways in which universities strive for academic excellence. The research programmes presented in this magazine demonstrate that striving for academic excellence does not conflict with the ambition to carry out research that is relevant to today’s global challenges. Many of the academics we interviewed claim that the joint pursuit of fundamental research and relevance is what makes their research highly rewarding and exciting. But can research be judged in terms of how relevant it is? Who actually determines what is relevant? And is social relevance really a scientific must? Ton Dietz, geographer and director of the Africa Studies Centre in Leiden in the Netherlands, is one of a growing number of academics who do not believe in a dichotomy between fundamental research that strives for scientific excellence and applied research that aims to be socially relevant. He believes that in the social sciences, it is almost impossible to distinguish between the two. Social developments influence research choices – and the outcome of research influences social debate and policy. This is not only a given for Dietz, but it is also something that is worth striving for. ‘As far as I am concerned, all social scientists should be obliged to reflect on the social relevance of their research findings’, he says. ‘They certainly should not be adding a quick paragraph about policy recommendations to their dissertations in the week before they submit, which happens a lot at the moment.’ Researchers in the physical and mathematical sciences, who were interviewed for this magazine, have all emphasized the cross-fertilization between basic academic knowledge and social relevance. This is not only about the potential future relevance of their work – insights that seem highly theoretical now may lead to very practical innovations in 100 years’ time – but also about the interaction between science and practice in the present. According to mathematician Arjen Doelman, the fundamental questions of mathematics are often triggered by real life phenomena, and the application of mathematics can lead to new theoretical insights. This, he argues, is an important part of how scientific knowledge grows. Entomologist, Marcel Dicke explains that immediately after formulating a fundamental research question, he will reflect on its possible social relevance. What do philosophers think about this? Is social relevance an academic duty? According to some philosophers, philosophy’s strength lies in its ability to distance itself from the issues of the moment. According to others, philosophy is valuable only if it manages to yield something useful – if it can be used in practice. Martin van Hees, professor of ethics and political theory at the University of Groningen, says his position lies somewhere between these two notions. On the one hand, his research is influenced by the questions that society is grappling with; and on the other hand, he believes that the dogmatic pursuit of obtaining a ‘social yield’ from scientific research is a deadend. ‘It is impossible to predict what the contribution of knowledge will be,’ argues Van Hees. ‘This is not only because our notions of what is valuable tend to change, but also because you cannot calculate social yield in advance. Trying to predict this could lead to a situation where funding is given only to academic work that has a clear, short-term purpose – meaning that research with a long-term purpose will fall by the wayside.’ But while we might accept that it is hard to predict if and how research can contribute to tackling the challenges that characterize the 21st century, society at large, and research funding agencies in particular, increasingly want proof that scientific work is ‘worthwhile’. Since the widespread adoption of bibliometric indicators in research evaluations, academic publication has become a goal in itself and citation scores have become crucial. For researchers, this has raised new types of questions. For example, why should climate researchers attend a two-week conference on climate change if it is not going to provide any publication points or contribute to the evaluation of their work? Laurens Hessels of the Rathenau Institute interviewed a wide range of scientists for his PhD thesis, 'Science and the Struggle for Relevance', which examined the relationship between the need to publish and the pressure for social relevance in the academic research system. He noted that researchers increasingly promised to deliver relevant results in order to get funding for their research – while at the same time being put under growing pressure to publish in academic journals. Hessels concludes that the evaluation of academic research needs to find a new balance. Too much emphasis on the quality of the science (measured with bibliometric indicators) hinders the alignment between research and social needs, while too much emphasis direction, it raises a number of important new questions. Are people in the South given a say in what research is relevant to their countries? And if so, who in the South should be judging the relevance of research proposals – policy makers, umbrella organizations such as the Council for the Development of Social Science Research in Africa, or local companies, NGOs and municipalities? WOTRO’s integrated programmes go a long way to establishing a joint determination of what is relevant. The research they fund has to be carried out in cooperation with academic and non-academic partners in the South. Inge Hutter, professor of demography at the University of Groningen, is a strong proponent of such an approach. ‘The stakeholder analysis that you are obliged to undertake as part of the proposal ensures that the central research questions are formulated in consultation with organizations and people in the field,’ she explains. Also, part of the research budget may be used for interventions. ‘This is a great leap forward from the old days when research and impact were strictly separated.’ The fact that WOTRO obliges this stakeholder analysis is promising. They are the funders, so they may have the power to urge universities to take relevance more seriously. The dogmatic pursuit of obtaining a ‘social yield’ from scientific research is a dead-end on applicability may threaten more fundamental lines of research. In recent years, the social relevance of research has received increasing attention, especially when evaluating research proposals. When deciding whether to give projects the go-ahead, many evaluation committees use potential for social relevance as a deciding factor. WOTRO, Science for Global Development – the largest Dutch funder of scientific research on development issues – is a case in point. Until very recently, research proposals were judged solely by academics. Now every proposal is also examined by a ‘social panel’. While this is a step in the right Han van Dijk, scientific director of the Research School for Resource Studies for Development (CERES), stresses that science may offer knowledge that no one specifically asked for. According to him, it would be undesirable to have all research questions formulated in consultation with social partners. Social partners have interests too, and some stakeholders, especially the poor and marginal, are often not involved in articulating the demand for research. Van Dijk stresses that science should not just be subservient to society, but also critical of society. ‘You now see that researchers are increasingly adapting their research proposals to respond to Synergy | 19 FEATURE certain stakeholders’ questions,’ he adds. ‘But this does not mean that these are the most relevant questions for society as a whole, or for marginalized groups. There is a risk that in wanting to be more relevant, you become less so.’ However, working with social partners is also enriching and can certainly contribute to the scientific quality of the research. Although research proposals are increasingly judged on their anticipated relevance, a retrospective evaluation of their social impact is still in its infancy. The platform, Evaluating Research in Context (ERiC), which was set up in 2006, aims of the research group. Clearly, this method poses new challenges. Han van Dijk notes that such an assessment may not be so simple where research involves small-scale farmers and poor slum dwellers as its main stakeholders. Furthermore, referring to the age-old question of attribution, Van Dijk stresses that any impact evaluation needs to bear in mind that it is generally impossible to prove a direct causal relationship between a specific research effort and a change in society. A new Standard Evaluation Protocol (SEP 2009–2015) was introduced in the Netherlands in 2009. This placed much more emphasis on evaluating the social Translating scientific complexity into lay terms is not only possible – it is fun to develop a way of measuring the social impact of research. ERiC’s starting point is that for research to have a social impact, there must be ‘productive interactions’ between researchers and stakeholders in society. These interactions can be direct (for example, through personal contact), indirect (through publications), or financial (through funding the research). The platform is developing and testing a method in which the research group being evaluated is asked to help develop its own evaluation framework by identifying its mission, context and main stakeholders. As part of the evaluation, these stakeholders are then asked for their views on the relevance Kant’s philosophy In his 1793 essay, ‘On the Old Saw: That may be right in theory, but it will not work in practice’, Immanuel Kant criticized the contrived rift between theory and practice. He argued that the soundness of theory (or research) depends on its applicability; and that unsuccessful application is clear evidence of poor underlying theory. 20 | Synergy impact of research groups in Dutch universities. It is expected that even more sophisticated methods of measuring social impact will soon be developed and adopted. For research to be used by nonacademic actors, communication with those outside the scientific arena is crucial. Eric Smaling, professor of sustainable agriculture at the University of Twente, says that, ‘to maximize the rate of return from investments in knowledge, it has to be shared with users. These users can be private-sector stakeholders who want to turn the knowledge into products, consumer organizations, NGOs working in the field, or political leaders involved in formulating legislation. Much greater effort is needed to bridge the gap between knowledge and policy.’ Few scientists are averse to serious political discussion. But is there enough incentive for them to devote precious time to matters other than writing for peer-reviewed journals? Conversation with academics at Dutch universities reveals that they are rarely awarded points for participating in public debates or for writing policy briefs and articles in trade journals or for Southern publishers. Nevertheless, most are making tangible efforts to use their research findings for purposes other than peer-reviewed publications, as many of the academics in this magazine confirm. Marcel Dicke, winner of the NWO Spinoza Prize in 2007, collaborated in a documentary based on his research into the merits of eating insects, which was broadcast on Dutch television. Dicke says that, ‘afterwards, several colleagues suggested it would be impossible to make such a film about their work, which supposedly was too complex! But I believe all academics should make an effort to bring their work to a larger audience – not least because it is paid for with taxpayers’ money. Translating complexity into lay terms is not only possible – it is fun.’ Knowledge is no longer the exclusive domain of universities. Other players, such as NGOs, who formulate their own knowledge strategies, have come onto the scene. The Dutch NGO, Hivos, for example, works closely with civil society organizations and academic centres worldwide through its Knowledge Programme. This programme is a practitioner–academic collaboration aimed at developing knowledge on issues central to the work of civil society organizations and the development sector at large. Cross-border and cross-sector cooperation and partnerships are increasingly important. Someone who is part of this new reality is Inge Hutter. Two of her PhD students work both at the University of Groningen, and at an NGO that operates in the area of their research. One of these students conducts research into the issue of fertility among people living with HIV/Aids. This subject fills a significant gap in academic literature, and at the same time responds to very practical questions that the NGO receives from its clients and partners in the field. ‘This sort of participatory research would not work for all my students,’ Hutter agrees. ‘But for those who have the interest, the opportunity and are able to do so, it is a great thing. To be honest, I find it increasingly difficult to supervise students who spend the full four years of their PhD behind their computer screens.’ Mathilde Miedema and Nicolas Chevrollier stress that innovative research is often driven by local demand. Both work at TNO, a Dutch organization for applied H H / Roel Burgler CoCooN – aiming for ‘double excellence’ scientific research and Europe’s secondlargest knowledge institute. Here, they run a programme for developing countries that helps innovation to reduce poverty. Part of this programme is the Flying Innovation Team – a rotating group of 20 researchers who spend 10% to 20% of their time on various social innovation projects across the world. These projects always involve local NGOs and businesses in order to ensure that the innovations are relevant to local demands. Chevrollier believes that the best innovations often arise from the interaction between researchers and endusers. ‘It is a type of co-creation,’ he explains. ‘Collaboration with NGOs and local businesses helps to identify local needs and can trigger all kinds of ideas. Furthermore, when introducing innovations, we can benefit from the networks of our local partners – businesses in particular.’ It is important that academics do not neglect the contribution of businesses. Universities need to explore how they can reel in the business sector without selling themselves out. And the corollary is true too – WOTRO, for example, should consider how it can exert influence on decisions made in boardrooms. This is already being achieved through knowledge networks, and the business sector’s participation is growing all the time. The stories in this magazine illustrate that excellence and relevance are two sides of the same coin. Research that increases our understanding of fundamental principles is often inspired by real-life phenomena, and is essential for addressing global challenges now and in the future. Likewise, research that seeks practical solutions to real-life problems is grounded in fundamental knowledge, and will ultimately contribute to new scientific insights. Realizing the potential of this interplay and synergy, there is increasing awareness of the importance of social relevance in the selection of research projects. But the circle will only be complete when a project’s relevance is considered at the end of the research process too. However, this kind of system would have to allay the fear felt by many scientists that too great a focus on relevance could lead to research being carried out only when it is clear that social yield can be measured afterwards. This would disqualify a large number of invaluable and creative research projects – projects that could have significant and completely unexpected relevance to our future. There should always be leeway for people with out-of-the-ordinary ideas, who excel in that great skill that many good scientists have: the ability to think outside the box. ■ CoCooN stands for Conflict and Cooperation over Natural Resources in Developing Countries. This new programme was set up by the Netherlands Organisation for Scientific Research (NWO) in collaboration with the Netherlands Directorate-General for International Cooperation (DGIS). It funds research related to conflict over natural resources and strives for ‘double excellence’ – excellent academic research and excellent social relevance. In order to enhance the social relevance of its research, only consortia comprising at least two academic and two nonacademic partners are eligible for research grants. Also, at least half the partners involved must be from the South. The CoCooN committee consists of both academic and nonacademic professionals, from the North as well as the South and it is the first approach of its kind in the Netherlands. Poverty, freedom and liberal politics For philosopher Martin van Hees, there is a very real connection between international development and theoretical questions such as: Do people have the right not to live in poverty? ‘Poverty concerns freedom,’ he points out. ‘You have negative freedom, which refers to the absence of impediments, and you have positive freedom, which means the presence of opportunities. Some liberals think that governments should focus primarily on negative freedom. This means they do not think the fight against poverty is a government responsibility. However, it can also be argued that poverty is an encroachment on negative freedom – and so it should be an important point on the political agenda for classic liberals.’ PROJECT Successful research requires courageous donors Organic locust control Locust and grasshopper plagues can have a devastating impact on agricultural production. However, the chemical pesticides used to fight them are dangerous too. After more than a decade of research, scientists have come up with a safe and effective organic alternative. L ocusts and grasshoppers regularly decimate crops in parts of Africa and Asia. Locusts in particular are well known for invading in swarms of millions, leaving behind ravaged fields – and ruined livelihoods. For many years, the preferred method of combating such plagues has been to spray chemical pesticides over the infested areas – usually using airplanes to cover vast areas of infestation. However, in June 2009, the Food and Agriculture Organization (FAO) of the United Nations reported that 10,000 hectares of Red Locust-infested land in Tanzania had been effectively treated with a biological pesticide. This prevented a full-blown invasion that was set to threaten the food crops of 15 million people. It was the first time that a biopesticide had been used on a large scale against a locust outbreak in Africa. Janny Vos is European business development manager of the CABI, a not-for-profit science-based development and information organization that aims to improve lives by solving agricultural and environmental problems. According to Vos, the success in Tanzania was the result of 13 years of collaborative academic research. The coordinated efforts of a large group of scientists – including ecologists, biologists, 22 | Synergy entomologist, chemists, economists, taxonomists and toxicologists – resulted in the development of an effective and safe biopesticide. And it also yielded an enormous amount of new scientific insight, published in no fewer than 120 peerreviewed publications. The research was inspired by increasing concerns about the negative effects of chemical pesticides on the environment and on the people living in the treated areas. After treating a major locust outbreak in Africa in the 1980s, it became apparent that spraying chemical insecticides kills other insects, animals and plants and can lead to chronic and acute health problems in people. In order for chemical insecticides to be used with any modicum of safety, it was necessary to evacuate human and livestock populations away from the infested areas. This was a solution that was completely impractical. In response to this reality, the international community called on research institutions to develop alternative ways of dealing with these infestations. In 1989 CABI submitted a research proposal to a consortium of donors. The thrust of the proposal was to find a biological solution to the locust problem. CABI’s plan was accepted and a research programme called LUBILOSA started the same year. LUBILOSA (LUtte BIologique contre les LOcustes et les SAuteriaux, or the biological battle against locusts and grasshoppers) was a collaboration of national and international research institutes in Europe and Africa. First, researchers needed to identify the kind of biological control that was most likely to produce results. They launched a survey in West Africa and the Arabian Peninsula to look for fungi that were dangerous to locusts and grasshoppers, but not damaging to beneficial insects, plants, animals or people. After screening more than 160 strains, one species, Metarhizium acridum was selected for further development. Field trials were carried out to test the fungus against almost all locusts and a number of grasshopper species in some twenty African countries. The trials showed that although the fungusbased biopesticide took a little longer than chemical pesticides to achieve results, it was just as effective, or often even more effective, than chemical alternatives. It also proved 100% safe for operators and those living in the communities where it was used, and had no adverse effects on other insects, fish or mammals. Lineair / Heuclin Daniel Fungus-based biopesticides – often even more effective than chemical alternatives Pleased with the success of the trials, the researchers fine-tuned the product to ensure optimum applicability and to lengthen its shelf life. The product was released commercially under the name Green Muscle. A company in South Africa registered the product and obtained a licence in 1998. A Senegalese company followed in 2008. As they went through the process of developing Green Muscle, the LUBILOSA researchers made major scientific progress. A number of their findings contributed to the knowledge of the biology and ecology of entomopathogenic fungi, a scientific area that is still largely unexplored. The scientific importance of these findings is reflected in the articles that were published in journals such as the Annual Review of Entomology.1 These publications allow researchers in different parts of the world to initiate work on fungus-based biological pesticides from a far greater base of knowledge. According to Vos, the success of the project is not only the result of the commitment of the programme’s multidisciplinary science team, but also of the commitment of its donors to support the program for an extended period of time. ‘The Netherlands can be proud, because they decided to fund the start-up phase of this project. This was a risky investment, as no one could be certain that the research would ever yield an effective biological pesticide. Daring to take such risks is essential for making innovations happen.’ ■ 1 Some articles by LUBILOSA researchers: •Kooyman, C., Bateman, R.B., Langewald, J., Lomer, C.J., Ouambama, Z. and Thomas, M.B.

Successful application of a biopesticide When a locust plague was about to hit Tanzania in 2009, the Tanzanian government, in collaboration with the FAO, decided to apply Green Muscle – the biopesticide developed by the LUBILOSA research project. According to Christiaan Kooyman, who was closely involved in the development of the product, some government officials in Tanzania were sceptical. They did not see the need to use biological products, and did not believe that this one would work. Kooyman was in Tanzania when the spraying started, and recalls people were euphoric when the first locusts started showing infection after the areas had been sprayed. ‘People were cheering: “it has started!”’ Synergy | 23 PROJECT Alamy / travelib prime Arequipa, Peru The politics of research ‘In the face of inequality, no science is neutral.’ That is the belief of Margreet Zwarteveen and Rutgerd Boelens, two water management researchers at Wageningen University in the Netherlands. They maintain, however, that scientific excellence can go hand-in-hand with a passion for justice. I n 2009, twenty-one social science research groups attached to Wageningen University took part in an international peer review. The Irrigation and Water Engineering (IWE) Group came out on top – out of 5, they scored 4 for scientific quality, 4.5 for productivity, and the 5 for relevance. Special mention was given to the interdisciplinary nature of IWE’s Programme on Water Rights and Social Justice. 24 | Synergy This international and interdisciplinary programme is being run by researchers whose passion for academia matches their commitment to making a better world. Margreet Zwarteveen and Rutgerd Boelens, who have been involved in this programme since it started in 2000, are academics with a clear political agenda. They want their scientific research to help achieve water justice for people worldwide. The guiding question behind their research projects is, ‘what is fair distribution?’. Because water is becoming a scarce commodity in more and more locations around the world, deciding who has access to it quickly becomes a political issue. One recent example is a case in Peru where the government diverted water from the mountains to a desert-like plain near the Irrigation systems neatly map a society’s power relations coast. Here, it is used to irrigate fields where, among other things, asparagus is grown for export to the Netherlands. This new irrigation system meant that Peruvian farmers in the mountains, who had previously used the water to grow food for their families, were suddenly and literally left high and dry. Traditionally, water research programmes concentrated on technical and economic issues. But the Water Rights and Social Justice Programme is innovative in that it adds a socio-political dimension to academic research on water issues. As Rutgerd Boelens explains, the usual focus of water research is on increasing efficiency. ‘The general idea is that, if the technology for dams, canals, sprinklers, etc. is top notch, then the market will do the rest,’ he says. ‘But water is more than H2O. Water is power. It irritates us that policy recommendations are usually presented as if they were neutral or objective, while in fact they are always based on a political choice.’ His colleague agrees. ‘The same goes for academic research. We do not believe that science is neutral,’ says Margreet Zwarteveen. ‘So we always make a point of clarifying our chosen perspective – in our case, that is the perspective of marginalized groups.’ Boelens and Zwarteveen were trained as engineers. But years of professional experience has made them question the goal of objectivity that often accompanies the technical sciences and adopt a less mainstream stance. ‘We believe that seeing scientific claims from a political perspective strengthens your arguments,’ says Boelens. Who are the marginalized groups that are central to Boelens’ and Zwarteveen’s research? Women, small farmers and indigenous peoples, such as the Indians in parts of South America, who have no say in water management issues. Such groups are systematically disregarded in national policies. Often, no account is taken of the social structures that local communities have developed, often over hundreds of years, to ensure access to water. In many villages, inhabitants acquired user rights by constructing their own irrigation system. Families’ water rights were gradually acquired over successive generations. A crucial factor for retaining these rights is that everyone works to maintain the irrigation channels. Then national legislation comes along and applies a completely different definition of water rights based on registered ownership of land and taxes paid. As a result, people do not feel responsible for governmentconstructed irrigation systems. If the water inlet, the channel or the pump is broken, no-one feels called upon to solve the problem. According to Boelens, who spent a number of years in farming communities in Ecuador, ignoring the social organization and institutions of rural communities is a classic pitfall of contemporary water management projects and structures. This is a subject that he deals with in detail in his article, ‘The politics of disciplining water rights’, published in 2009 in Development and Change.1 This and other publications testify to the innovative way in which Boelens, Zwarteveen and close colleagues combine technical and socio-political research. For instance, they argue that irrigation and canalization systems neatly map a society’s social relationships and power relations. The layout of an irrigation system – which includes certain houses, villages and plantations and excludes others – shows very clearly who is at the tail end of the system. It is usually the person who is at the tail end of society as well. Similarly, technical design choices often speak volumes about the balance of power in a society. For example, the decision to not include a night reservoir, which would allow night-time crop irrigation, means that people have to use the water whenever it becomes available. For women this is often tricky because their daily routines are dictated by other care tasks, and they are unable to irrigate their fields at night for safety reasons. Not including a night reservoir means, in effect, female farmers lose a large portion of their water rights. According to Zwarteveen, this is just one example of how recent neoliberal reforms in the water sector are participatory and gender-sensitive only on paper. In reality, gender is still a blind spot, with substantial consequences for policy effectiveness. This was exactly what amazed her during the years that she worked for the International Irrigation Management Institute (now known as the International Water Management Institute [IWMI]), which has its international headquarters in the Sri Lankan capital Colombo. ‘In scientific studies and policy papers both the farmers and end-users were always assumed to be men,’ points out Zwarteveen. PES Changes in policy fashions in a country and its political-economic situation may give rise to new research questions. The discussion on biofuels is a typical example of this, as is the debate on the growing mining industry in Peru, which is responsible for largescale water contamination. The hype around incentives such as Payments for Ecosystem Services (PES), promoted by nature organizations and environmental economists, is another example. ‘In Ecuador and Costa Rica the introduction of PES was presented as a success story,’ says Rutgerd Boelens. ‘And our Peruvian colleagues told us that their government was also interested in the idea. We then carried out research which showed that only a small number of communities actually benefited from the system, while most villages were extremely unwilling to relinquish their land-use autonomy. In effect, PES represents the introduction of a market mechanism for public goods which can hinder collective water usage and maintenance rules. That is another reason why is it so important to re-evaluate every local situation.’ Synergy | 25 PROJECT HH / Nature Picture Library Water research should focus on justice rather than efficiency ‘Women, who were often the ones working in and irrigating the fields, were invisible. After several years I got tired of constantly fighting against such entrenched ideas, not least because it puts your own intellectual development on hold.’ Zwarteveen returned to Wageningen where, together with like-minded academics, she formulated a more progressive research agenda. One of many products of this is a 2009 publication in the peer-reviewed journal Gender, Place and Culture.2 This article was co-authored with Rhodante Ahlers of IHEUNESCO Institute for Water Education in Delft. In it Zwarteveen argues that feminist reflections about tenure-insecurity and social inequities in relation to water are at odds 26 | Synergy with a neoliberal framework that renders invisible the politics and power relations involved in water allocation. Remaining true to her epistemological stance, Zwarteveen would like to extend this line of argument to the politics of academia. The question that begs to be answered is: ‘What effect does the fact that the world of water is such a man’s world have on the main academic research questions, the research approach, and the outcomes and translation of these into policy?’ In 2008, Rutgerd Boelens, was awarded his doctorate degree, with distinction, from Wageningen University. The same year, the Amsterdam Institute for International Development (AIID) awarded him the prize for the best PhD thesis of 2007–2008. The combination of high quality research and a focus on social relevance were what earned him this accolade. Unfortunately, the criteria that underlie the tenure track system that was introduced at his university in 2010, allow for very little formal appreciation of the ‘social impact’ of Boelens’ research. As Zwarteveen explains, ‘we are judged primarily on the basis of our publications in peer-reviewed journals. Most professional or popular scientific publications generate zero points for our tenure tracks.’ She laughs and adds, ‘what this in effect means is that we work twice as hard. Because we refuse to give up what we stand for.’ Zwarteveen and Boelens both believe it is important to link research networks together – for example, critical scientists in the North and the South, organizations of male and female farmers, and NGOs and policy makers interested in social justice. Many of the concrete results of Boelens’ and Zwarteveen’s research can be traced back to these local and global networks. Action research with local partners in Bolivia and Ecuador resulted in significant changes in recent national constitutions and in water-related Bills. In Ecuador the government is discussing water systems as social constructions – this would have been unthinkable 10 years ago. And in a totally different part of the world, the structure of the Nepalese national government’s irrigation department is changing. But just as rewarding as these concrete achievements, Boelens and Zwarteveen feel, is the fact that they are training a generation of young scientists who learn to see the inbuilt biases in academic research and to reflect on these in an open and critical way. Many of these young scientists come from abroad, and they take home with them what they have learned. Collaborative programs with universities in South Asian and Andean countries further contribute to the fact that the Wageningen approach is increasingly used as an example of the truly interdisciplinary research that is needed to tackle complex water problems and the ethical issues they are tied up with. ■ Boelens, R.

RESEARCH NEWS Shorts ICT innovations in Africa Africa may not be the traditional breeding ground for technological innovation. But in the last few years, Africa has been the stage for some highly successful international ICT developments. For example, during the post election violence in Kenya in 2008, Kenyan scientists developed software to monitor the time and location of riots. Someone witnessing a riot could send an SMS, the software would read their exact location and add it to a map on a specially designed website. In this way, civil authorities had access to a real-time picture of the location and intensity of the violence. The developers called the software Ushahidi, which means ‘testimony’ in Kiswahili (www.ushahidi.com). Now, this software is also being used to track medicine shortages across Africa. And after the earthquakes in Haiti and Chile in 2010, it helped to connect victims with emergency workers. The idea that ‘northern scientists’ develop new technology for dissemination to ‘southern recipients’ is as obsolete as ... old technology. The positive effects of the brain drain Ranking universities Rankings of the best universities in the world are generally topped by universities such as Harvard and Stanford in the United States and Oxford and Cambridge in the United Kingdom. There are usually no Dutch universities in the top ten. But, unlike many other countries, all the Dutch universities tend to score well. In 2010, 12 Dutch universities were listed in the top 500 of the renowned Shanghai Jiao Tong-ranking, with Utrecht University ranking 50th (www.arwu.org/ARWU2010.jsp). Times Higher Education’s 2010–2011 rankings has ten Dutch universities in its top 200. There are also two African universities on this list. University of Cape Town at 107th and Alexandria University at 147th (www.timeshighereducation.co.uk). Many educated people from developing countries end up working overseas. For example, 47% of Ghana’s university graduates live outside the country. Recently, it is being argued that this type of ‘brain drain’ migration can have positive effects on local economies. A World Bank report produced by John Gibson and David McKenzie of the University of Waikato in New Zealand outlined research into the migration of highly skilled workers from Ghana, Micronesia, New Zealand, Papua New Guinea and Tonga. It showed the positive effects of a highly educated diaspora in terms of developing the local economy through remittances, trade, foreign direct investment, and knowledge transfer. It also found that migration is highly beneficial for the skilled workers themselves – typically earning twice to three times as much as they would have done at home. 77 13 % of researchers come from the EU, Japan, America, China and the Russian Federation – representing one third of the world’s population. 79 out of every million sub-Saharan Africans are involved in research – that is less than 1% of the total number of researchers in the world. % of the population in the developing world used the internet in 2007 –compared with 64 percent in the developed world. 33 % above average – that is the citation impact score of Dutch academic work. Only Switzerland and America score higher. Synergy | 27 Essay Different methods, common values In a critical essay, development policies consultant, Shobha Raghuram, based in Bangalore, India, reflects on the routes that science and development knowledge take in building a more equal world. Shobha Raghuram is a development analyst who carried out postdoctoral research in philosophy at the Sorbonne in Paris. She worked at the Centre for the Study of Developing Societies in Delhi, before joining Hivos as director of the regional office in Bangalore. Raghuram has worked at Harvard as a visiting senior fellow. She is currently working on her book, Rethinking Development. U neven development and persistent social conflict have left their mark on most countries in the early 21st century. Major advances in science, technology and industry exist side-by-side with poverty and discrimination. In this context, the perception that the scientific community is isolated from development issues has led to debates on the social responsibility of scientists. We ask whether excellence excludes relevance in terms of immediate applicability. But it is missing the point to assume that the social relevance of a study can be determined by its potential for immediate application. Scientists and development workers are united by a common citizenship. As development workers struggle to change systems that perpetuate grave inequalities, scientists remain their allies. Development and the pursuit of research are not as far apart as we often assume them to be. As an academic I have worked with some of the most committed and uncompromising social scientists. I have never had occasion to think that their world was different in its aspirations from the more equal world that people living 28 | Synergy in poverty dream of in their formidable struggle for equality and identity. It was from the poorest of the poor that I learned about power and powerlessness and it was through my engagement with them that I learned to put aside the myth that social theories are neutral. Many of the social scientists I have worked with are well aware that science is not value neutral. Many of them have been at the forefront in struggles with their governments for social justice. What they believe in and what they do has been described powerfully in the words of French philosopher, Michel Foucault. ‘It is a duty of an international citizenship to always bring the testimony of people’s suffering to the eyes and ears of governments, suffering for which it is untrue that they are not responsible. The suffering of men must never be a mere silent residue of policy. It grounds an absolute right to stand up and speak to those who hold power.’ It is neither fair nor realistic to propose that all scientific research should be relevant. The formulation of ideas is often far ahead of their pertinence to immediate needs. In the world of development, the issue is whether research should be dependent on the immediacy of needs, or on imagination Reuters / Nayef Hashlamoun ‘ The suffering of men must never be a mere silent residue of policy’ – Michel Foucault and the search for ideas that are often well ahead of their time and difficult to map, one-to-one, onto specific problems and situations. By contrast, in the world of pure science, major funding priorities were traditionally determined by the internal developments of subjects such as physics, chemistry and mathematics. However, more and more scientific research funding is being directed towards areas, such as information science, biological science, nanoscience, and climate science – all of which have the appeal of potential for immediate application. Even in universities such as Harvard, whose budget outstrips the GDP of many countries; and in nations such as the United States, Japan, and Finland, the budgetary allocations for development studies are often minuscule compared with those for science and technology. This underscores the lack of support for and the underlying judgmental attitude towards the fundamental issues of development and social discord. Investment in R&D for university teaching, for capacity building, and for development aid are being ever more reduced on the grounds that they fail to solve the problems of the poor in an efficient manner. While trade has globalized, international development cooperation has been marginalized. Development research relevant to issues in Southern countries has had an impact on Northern countries too. The work of Indian economist, Amartya Sen, a professor at Harvard University, originated to a large extent in western universities. His work deals principally with development in the South – but the issues he addresses have universal value. The best-selling authors in India’s Oxford University Press write primarily about development. The issues they discuss often have implications that go beyond the geographical or institutional settings of their work. The late Mehbub Al Haq, renowned Pakistani economist and pioneer of human development theory, is another example of a scientist searching for universal values. His work on the UNDP Human Development Report employed cutting-edge economics to force governments to review their own performances in social sectors. Long-term support for researchers and freedom to pursue their goals are the cornerstones of excellence in any field, including development. Similarly, freedom is fundamental for building civil-societyinitiated alternatives that contribute to global equity and peace. But freedom also has its dark side and science must be at pains to avoid contributing to our civilization’s excesses. A political and moral will must guide science as much as it must guide development. Millions of displaced people, the victims of poorly designed development programmes, are reminders of the need for norms in the conception and execution of development programmes. In any working democracy, the fostering of competing knowledge systems must become an essential part of the culture of generating ideas – and, as Einstein once told us, the important decisions taken in any democracy ‘depend ultimately on decisions made in the village square’. n Synergy | 29 INTERVIEW Freedom for ideas Menno Bijleveld Professors Jaap Sinninghe Damsté, a molecular biogeochemist, and Wil Roebroeks, an archaeologist, share a passion for the distant past. They also both belong to the select company of Dutch scientists who have been awarded the ‘Spinoza Prize’. In 2010, we met up with the two laureates at the public library in Amsterdam, where we discussed the relationship between scientific excellence and social relevance. The scientific disciplines of archaeology and molecular biochemistry are not usually associated with social relevance. In what ways do you think your research addresses today’s global challenges? Wil Roebroeks is professor of palaeolithic archaeology at Leiden University. In 2007, he received the NWO Spinoza Prize for his original observations about the development of early human society. Roebroeks addresses questions on our origins and on the development of human societies. According to the Spinoza jury report, Roebroeks is an independent, innovative, and unorthodox researcher and the most prominent Dutch archaeologist both nationally and internationally. 30 | Synergy Roebroeks: Many debates on the relevance of academic research focus on its economic relevance. From that narrow perspective, I have to admit, my academic work is scarcely relevant.1 From a broader perspective, however, archaeology contributes to a vision about how the earth and its people have developed over time. This knowledge helps us to understand complex developments in today’s globalizing world. Archaeology may even give people a sense of their place on earth. I realized this a couple of weeks ago as I was holding a Sunday morning public lecture. I was surprised at the turnout to hear my academic story on that sunny morning. Being in a former church, now converted into the Paradiso music and culture temple, I wondered whether some of the people were there because they hoped to get a secular insight into why we are on earth. I think you could argue that archaeology is relevant in terms of giving people a sense of belonging in what seems an eternal history. But this philosophical angle does not relate to the type of relevance that people generally refer to when they speak about science. As a Pleistocene archaeologist, you study people and human society from about 12,000 to 2.5 million years ago. What does this tell us about our contemporary world? Roebroeks: It places current developments in a historical perspective. For example, I always tell our first year students that we are all migrants in our own country. The Neanderthals were the natives in Europe, while our ancestors were migrants from Africa. In fact, genetically, humans are constantly changing. Hunters and gatherers who roamed Europe 10,000 years ago were genetically different from the farmers who settled here a bit later. And those early farmers are genetically different from us. What does research in the field of biogeochemistry tell us about such developments? Sinninghe Damsté: I study an even more distant past than archaeologists. My work concerns developments some 100 million years ago.2 The group I work with is analyzing chemical substances in old sediments from oceans and lakes. Using a paleothermometer, we can determine what water temperatures were in the past. It is an innovative method and we come across a good deal of scepticism. People have a hard time believing that it is possible to measure past temperatures. Nevertheless, this method clearly shows us how the climate has been changing over the course of several hundreds of millions of years. I tell my audiences that, if current trends continue, before the end of this century the amount of CO2 in the atmosphere will have reached the level tit was at 93 million years ago. Back then, the tropical oceans had a temperature of a staggering 37 degrees Celsius. From the perspective of a biogeochemist, who sees this from the perspective of thousands or millions of years, this is not too dramatic because the past has shown that biological life can deal with considerable fluctuations in temperature. But that is not the usual perspective in social thinking. Most people are interested in the small, and relatively recent, period of life associated with Homo sapiens. And for this particular species, the consequences of such temperature changes are likely to be dramatic, not least because of the associated rise of sea levels. Roebroeks: During periods of global warming in our hunting-gathering past, these mobile people would simply migrate to other, higher areas. But today, there are too many of us to simply pick up and leave. In addition, in many regions, there is little space left to migrate to. And that is before we even consider that other major problem: we have become a sedentary species and we are all too emotionally and economically tied to our real estate! Sinninghe Damsté: True. So in public lectures, I share some of the basic scientific insights about climatic variations in the past to increase people’s awareness of the urgency to address human-induced climate change. We scientists are sponsored by society – it is tax payers’ money that keeps our work afloat. I consider my public lectures one way of returning the favour, and giving something back to society. Menno Bijleveld So from that perspective, there is no such thing as ‘the Dutch people’. It is of course a little bit far-fetched to relate archaeological insights to contemporary debates on migration, but it often triggers interesting moments of reflection. Providing students with a wider perspective on current social challenges is important. So I happily seize the opportunities my discipline offers for generating some critical social thinking. Sinninghe Damsté: This is very similar to what I do when I step out of my scientific corner to enter the social debate. When giving public lectures, for example, I try to place my scientific findings in the context of today’s global challenges. As such, I do not only hope to trigger people’s fascination for science, but I also hope to increase their awareness and understanding of current developments on earth – and the gravity of some of these. Jaap Sinninghe Damsté, a biogeochemist, is head of marine biogeochemistry at the Royal Netherlands Institute for Sea Research and professor of molecular palaeontology at Utrecht University. He received the NWO Spinoza prize in 2004. He uses organic compounds from ocean and lake sediments to reconstruct the life and climate of earlier epochs. Sinninghe Damsté has more than 470 publications to his name, some 30 of which have appeared in either Science or Nature. Synergy | 31 INTERVIEW For me, the excitement is in the puzzle ... trying to reconstruct aspects of a very complex past is extremely exciting – Sinninghe Damsté Do scientists have an obligation to society? Roebroeks: I do not think that scientists have a moral obligation to carry out research that is immediately relevant to society. It is usually sheer curiosity-driven research that generates the new kinds of knowledge we have become so dependent on. But I do think that scientists have an obligation to share their findings and knowledge with society. We should try and make it intelligible for the interested public, and where possible, contribute our specialist knowledge to social debates. Sinninghe Damsté: I do make an effort to make my science understandable. But society is not the starting point for the formulation of my research questions. My science is 99% driven by curiosity. For me, the excitement is in the puzzle – trying to reconstruct aspects of a very complex past is extremely exciting. I did not start analyzing the chemical substances at the bottom of oceans and lakes because I was looking for a way of predicting climate change. It was only gradually that we discovered that our methods and findings could contribute to this. It was a coincidence. To me, this underlines the view that researchers should be free to follow their academic intuition. This freedom is a prerequisite for innovation. Often it is only after 20 or even 40 years that we can tell whether or not our ideas have proved useful to society. Think of the microbiologist Alexander Fleming who discovered penicillin. His accidental discovery in 1928, which as it turned out marked the start of modern antibiotics, was mostly the result of his passionate scholarly curiosity and untiring experimentation. And it was more than ten years later that his 32 | Synergy initial discovery became the wonder drug of the 20th century. Roebroeks: Breakthrough ideas often come from ‘scientific freaks’, people on the fringes of established science. They will never be able to develop their ideas if they are forced into a straitjacket. Taking away a researcher’s freedom is about the worst thing you can do. So what is the relationship between scientific excellence and social relevance? Sinninghe Damsté: It is certainly fascinating when you discover that your scientific findings are useful for tackling social problems. And it can be rewarding to use your findings to give a wider audience an interpretative nudge to think in a certain way. But it is not our task to moralize or preach about life and the ways of the world. Anyway, our audiences are usually too smart to be swayed by this. Relevance is a definite bonus, but excellence lies in the originality of a scientist’s work, its impact on scientific paradigms, and in a researcher’s independent and innovative way of thinking. Roebroeks: When I left school I chose – despite my strong interest in the subject – not to study archaeology. Those were the days of Vietnam and Chili. I felt that archaeology was irrelevant to the political and social urgencies of the time. So I studied contemporary history ... but now I see the relevance of a discipline that provides insight into how human societies developed and organized themselves. Do you ever wonder how come we are sitting here talking clever talk and enjoying the view over historic Amsterdam when we could have still been having fun swinging through the trees? But more importantly, all scientific study has something invaluable to offer: we recommend to students that they ‘think critically and take nothing at face value’. I strongly believe that we need science in order to build and maintain a democratic society. In scientific practice, it does not matter who says what, it is the strength and solidity of the arguments that counts. And that is something that no democratic society can ever afford to lose. ■ Professors Jaap Sinninghe Damsté and Wil Roebroeks were interviewed by Koen Kusters and Ellen Lammers Some examples of academic work by Wil 1 Roebroeks: •Dennell, R. and Roebroeks, W.

E nvying, or being envied, is a feeling that most of us have experienced. But what does envy do to us? Is it necessarily a negative emotion? In the 1960s, sociologist Helmut Schoeck gained international fame with his book Envy: A theory of social behaviour. He saw envy primarily as a destructive force – and an impediment to development. Referring to the ‘envy-barrier of the developing countries’, he argued that envy is such a prevalent emotion, that people continuously fear being envied. As a result, they stop trying to improve their lives, which holds back the development of their countries. Most research in psychology and economics confirms that the envious want the envied to fail, and are even willing to actively make that happen. However, research that several colleagues and I recently carried out on the psychology of envy reveals that there are two types of envy – malicious envy and benign envy. Malicious envy is the destructive emotion mentioned by Schoeck and others, but benign envy is a more constructive emotion. We found benign envy among, for example, students whose envy of a star student prompted them to devote more time to their own studies. And I would dare to argue that benign envy can also stimulate development. THE DISCOVERY OF envy helps to shed a very different light on the role envy plays in development. Aid, by definition, supports some people more than others – it is impossible to help everyone equally at the same time. This creates inequality, the breeding ground of envy. What determines whether benign or malicious envy is elicited is how deserving the recipients of the development aid are perceived to be. If people see the gains of another as deserved, the envy they feel is more likely to be benign. Malicious envy is more likely if the advantage is thought to be undeserved. This seems consistent with idea of ‘ownership’ in development aid. Support is deserved when recipients take the initiative and assume ownership. In the context of development, to ensure that the envy that is evoked is benign and usable as a motivating force, it is important If people see the gains of another as deserved, their envy is more likely to be benign that it is the population that decides who deserves development aid, and not the donor. In this way, well-designed aid can ignite a constructive envy that acts as a spur for development rather than as an impediment to it. To fully understand the effectiveness of development aid, it helps to study the emotional responses it evokes. The effects of such emotional responses are important – both for the effectiveness of the aid itself, and for our understanding of human behaviour. ■ Niels van de Ven is assistant professor of social psychology at Tilburg University. In 2010, he won an award for defending the best PhD dissertation. We asked him how his psychological research could offer a better understanding of the complex processes of development. His answer lies in the relationship between development, aid and envy. Synergy | 33 PROJECT Catalysis – producing sustainable biofuels Scientists: top-class athletes? Groundbreaking research on the workings of solid catalysts in chemical reactions paves the way for sustainable production of fuel from biomass – heralding the end of fossil fuels. B Lineair / Joerg Boethling ert Weckhuysen’s research on catalysis plays an important role in the development of smart techniques to transform biomass into biofuels. This has attracted a good deal of attention in recent years because it can help to decrease the CO2 emissions that lead to climate change. But Weckhuysen is adamant that he would never choose a research topic just because it was fashionable. For him, the goal of excellent research is to contribute new scientific insights and concepts. ‘Hopping from one topic to another does not usually bring science further. You need to get your teeth into an idea and hold on to it,’ Weckhuysen explains. ‘In this way, science is like topclass sport. It requires drive, persistence and passion. And just like sport, it involves competing with peers. You do not want to play in the third division of some provincial league, you want to play in the champion’s 34 | Synergy league. So you keep in shape. For a scientist, that means careful reading of the literature. If you want to stay ahead, you have to know what is going on in the scientific world.’ Weckhuysen and his group research how solid catalysts work. A solid catalyst is a substance that changes the rate of a chemical reaction, but is not itself consumed by the reaction. About 85% of all processes in the chemical industry use one or more catalyst materials. Liquid or gas molecules are brought into contact with a solid catalyst, which triggers a range of brief chemical reactions with the catalyst’s surface. As this occurs, some chemical bonds are broken and new ones are formed – but the catalyst emerges unchanged. Using the technique of spectroscopy, which involves the interaction between light and matter, scientists have been analyzing the catalyst materials before and after catalytic reactions. Up to recently, virtually nothing was known about what happened in between – the actual dynamics of the catalyst reaction remained a black box. During the mid 1990s, Weckhuysen decided to try to unravel this mystery. He realized that, in order to really understand the mechanism of catalysis, he needed to discover what was happening to the molecules and atoms while the action was taking place. He decided to bring spectroscopic methods to the place of action without making too many compromises. He called this operando spectroscopy. Using this approach, he managed to shed new light on what was happening to the molecules and atoms on a catalyst’s surface during the reaction. Today, Weckhuysen is a world leader in this field of research. While up to recently scientists assumed that catalyst solids are spatially homogeneous objects, Weckhuysen and his team found that these catalysts are actually highly complex because they possess both active sites and non-active regions in their porous structures. ‘A solid catalyst is like a piece of cheese with holes,’ Weckhuysen explains. ‘But some of the holes are too small for molecules to enter or may be dead ends, which slows down the catalytic reaction considerably. To increase the efficiency of the catalyst, you need to make sure that your cheese has plenty of large holes.’ Sometimes industry poses intriguing questions that arise out of everyday experiences The findings of Weckhuysen and his team were published in journals including Nature, Nature Materials, the Journal of the American Chemical Society, and Angewandte Chemie 1. They also attracted the interest of the chemical industry, which needs this type of knowledge to develop new (or improve existing) production processes. Weckhuysen’s science is particularly important in the search for smart ways of producing products from biomass, such as biofuels, chemicals and bioplastics. This is a relatively new industry, based on catalytic reactions. Triggered by the potential of biomass, a number of Dutch chemical companies started collaborating closely with Utrecht University and other Dutch universities and research institutes in a research programme called CATCHBIO (Catalysis for Sustainable Chemicals from Biomass). Weckhuysen is very enthusiastic about this type of collaboration between science and industry. ‘Our perspectives clearly differ; industry tends to have a utilitarian perspective, while we have an academic perspective, but there is also a lot of synergy. Sometimes industry poses intriguing questions that arise out of everyday experiences, and in our efforts to answer those questions, we often generate new scientific insights.’ New techniques to produce fuel from biomass are likely to have an important impact on developing countries. Currently, most biofuels are produced from feedstock crops such as oil palm, corn and sugar cane. These first-generation biofuels can be produced using relatively simple techniques. The downside is that the cultivation of crops for biofuel production may compete with food production, so biofuel has been blamed for compromising food security in developing countries. In addition, environmental organizations have associated agricultural expansion for biofuel production with deforestation and biodiversity loss. In response to these concerns, there is a move to develop second-generation biofuels using agricultural waste and non-edible organic matter. This however is a much more complex process requiring sophisticated catalytic reactions and related catalysts to transform non-edible lignocellulosic components of biomass into fuels. And that is where science comes in. Weckhuysen: ‘One of the biggest challenges in the coming years will be to develop new catalyst materials that can efficiently transform waste materials into sustainable biofuels and other chemicals and materials of the future. Developing such catalysts can only be done on the basis of a detailed knowledge of how they work.’ ■ Some articles by Bert Weckhuysen: 1 •Karwacki, L., Kox, M.H.F., de Winter, D.A.M., Drury, M.R., Meeldijk, J.D., Stavitski, E., Schmidt, W., Mertens, M., Cubillas, P., John, N., Chan, A., Kahn, N., Bare, S.R., Anderson, M., Kornatowski, J. and Weckhuysen, B.M.

Synergy | 35 PROJECT Treatment of oral infections in Tanzania Research is like a Ferrari A recent research project discovered an alternative method for treating oral fungal infections. The work, which yielded widespread academic praise, will improve medical treatment for HIV/Aids patients in Tanzania. ‘I New research ideas Omar Hamza from Tanzania explains how research can lead to new ideas: ‘While researching oral fungal infections, I studied what traditional healers were prescribing for HIV/Aids patients with fungal infections, and identified at least 55 plant species that that they used. Based on in vitro testing, I discovered that some of these show promising antifungal functions. I hope to follow up on this finding with more basic research to find out whether some of these plants can provide ingredients for new medicines.’ 36 | Synergy t is all about beauty,’ says André van der Ven. ‘I find beauty in academic content, but the applicability of research is just as beautiful. And the best thing is when both come together. It is like a Ferrari: The car itself – its design – is astonishing ... and being able to drive it is the icing on the cake!’ Van der Ven works as a medical doctor and infectious diseases specialist at the Radboud University Medical Centre in Nijmegen. He becomes animated as he starts to speak about a recent research project on the treatment of HIV/Aids patients with oral fungal infections in Tanzania. He emphasises the study’s ‘double beauty’. First, its design was state-of-the-art according to the latest and highest scientific standards of clinical research. Second, the applicability of the research proved enormous and it had the potential to change the lives of thousands of patients. The study’s results were published in a number of journals1 and one article was selected by the American Society for Microbiology and Infectious Diseases as one of the ten most valuable publications on fungal infections in 2008. This academic recognition is, according to Van der Ven, related to the strength and simplicity of the research question in combination with the scientific rigour of the study itself and the applicability of its results. The majority of people living with HIV/Aids in Tanzania develop an oral fungal infection (oropharyngeal candidiasis), which is a very uncomfortable condition that often leads to weight loss. A small dose of a medicine called fluconazole once a day for one or two weeks is a common treatment. In theory this is effective, but in practice it often fails. Patients sometimes take the pills for only a couple of days before passing on the remainder of their prescription to family or friends. Not finishing the course of treatment can cause the infection to recur, possibly in a more resistant form. Intrigued by this practical problem, Van der Ven came up with a hypothesis that is as brilliant as it is simple: could the fluconazole be administered in a single large dose? Van der Ven and his Tanzanian colleague Omar Hamza of Muhimbili University designed a randomized controlled trial to compare the experimental treatment with the standard one. Hamza conducted the trial in 2006 and 2007. He Reuters / Howard Burdit A healer shows her traditional medicine recruited 220 HIV-positive patients with a clinical and microbiological diagnosis of oropharyngeal candidiasis. One group of 110 was given the common daily treatment for two weeks, the second group of 110 patients was given an experimental treatment of five pills taken all at once. Hamza found that the experimental treatment was every bit as effective as the common treatment, and discovered no negative side effects. This finding has reality in developing countries. ‘I worked as a doctor in Botswana for six years,’ explains Van der Ven. ‘This made me aware of the practical challenges of healthcare in poor areas. It was then that I started to realize that the simplification of medical treatments can have enormous positive health effects. People often think that improving people’s health lies in discovering new medicines. But we can also gain a lot by Tanzanian and Dutch researchers felt equal ownership of the research, and their enthusiasm was mutual too. ‘The Dutch and Tanzanian collaborators were equally excited about the work,’ says Van der Ven. ‘They were inspired by the beauty of its academic content as well as by the applicability of the results to improve medical practice in Tanzania.’ ■ See for example: 1 The simplification of medical treatments can have enormous positive health effects •Hamza, O.J.M., Matee, M.I.N., Moshi, M.J., Simon, E.N.M., Mugusi, F., Mikx, F.H.M., van Palenstein Helderman, W.H., Rijs, A.J.M.M., van der Ven, A.J.A.M. and Verweij, P.E.

He advised the Tanzanian health department on the treatment of fungal infections and compiled a manual for the new treatment. The study is a good example of rigorous clinical research that is geared to everyday researching how to apply what we already have more effectively.’ Van der Ven highlights two additional factors that help to explain the success of the study in Tanzania.

It was known that it had a long halflife so that a single-dose treatment was theoretically possible. Second, the research was conducted in the context of a strong collaborative relationship.

Synergy | 37 PROJECT Reuters / Finbarr O’Reilly Managing water variability in sub-Saharan Africa Integrating disciplines In the field of water management, combining various academic disciplines helps to yield new scientific insights. This is essential for improving agricultural productivity in sub-Saharan Africa. P ieter van der Zaag is professor of integrated water resources management at the UNESCO-IHE Institute for Water Education in Delft. He believes that bringing different scientific disciplines together in one research programme creates exciting possibilities – in terms of both social relevance and scientific excellence. In terms of relevance to society, combining 38 | Synergy disciplines is essential for reaching the level of understanding that is needed to solve the complex problems of water management issues. In terms of scientific excellence, multidisciplinary research inspires the scientific synergy, cross-fertilization of ideas and outof-the-box thinking that lead to innovative research questions and new perspectives on old problems. Combining scientific disciplines was one of the main characteristics of the Smallholder System Innovations (SSI) Programme, coordinated by Van der Zaag between 2003 and 2009. This extensive research programme on water management systems in sub-Saharan Africa focused on two river basins, one in Tanzania and the other in South Africa. Van der Zaag believes To tackle poverty, you need to understand it, and understanding poverty in all its complexity depends on excellent research that scientific understanding of water management systems is pivotal for designing effective strategies to increase agricultural productivity in sub-Saharan Africa. The availability of water in the semi-arid savannah areas is highly volatile; flood can follow quickly in the footsteps of severe drought. This unpredictability makes the risk of crop failure very high. And it is because of this that managing water variability should be a core component of any innovation designed to improve agricultural productivity. Water systems are enormously complex and influenced by myriad biophysical and socio-economic factors. For this reason, the SSI programme involved researchers from a wide range of scientific disciplines including agricultural specialists, soil scientists, ecologists, hydrologists and institutional experts. A soil scientist studied the microbial activity in a sample of land. Agriculturalists studied the ways in which farmers used their natural resources – for instance, they assessed how different ploughing methods influenced the infiltration and storage of water in the soil. Hydrologists studied the variations in river flows over a period of time. This research generated the data needed to understand the complex hydrological processes that govern water availability. The research programme lasted for six years and has been documented in six PhD theses and 28 peer-reviewed articles so far.1 The publication record of the project reflects the varied range of research from monodisciplinary to truly interdisciplinary. Among the universities who took part in the project were Sokoine University of Agriculture and the University of Dar Es Salaam, both in Tanzania, the University of KwaZulu Natal in South Africa, Stockholm University in Sweden, the University of Zimbabwe, and Delft University of Technology in the Netherlands. Research conducted in Tanzania by Dutch hydrologist, Marloes Mul, illustrates how monodisciplinary and interdisciplinary research worked together in the SSI programme. She measured diurnal fluctuations in river flows and found that these were due to variations in evaporation between day and night – this is a groundbreaking scientific discovery in hydrology. Mul also crossed the boundaries of her own discipline by working with an African social scientist and an agricultural engineer who were studying water management institutions in the same area. Their combined data provided an unconventional mix of hydrological information and information on indigenous water management practices. This showed that certain locally developed water-sharing arrangements based on systems of small canals bringing water from mountain streams to crops and livestock were highly effective in regulating water flows and ensuring a minimum water supply for a large group of farmers. ‘When developing interventions to improve people’s access to water, you need to understand the age-old water management arrangements that exist between individual farmers and between villages,’ Van der Zaag explains. ‘You have to find out how and why they work – or do not work. Then you can identify which elements can be applied elsewhere. ‘No single research finding will revolutionize farming practices in Africa,’ he adds. ‘The SSI project generated many small findings that together help to advance the understanding of farming and water management systems. These findings contribute to the scientific knowledge base and feed into the curricula of the universities that participated in the programme. Not least, these findings are also being used to develop practical solutions such as building underground water tanks to store the water that runs off the land after a heavy downpour. This can be used to tide farmers over during times of drought.’ When asked about the relationship between scientific excellence and relevance to developing countries, Van der Zaag responds ‘It all starts with the need for a better world. To tackle poverty, you need to understand it, and understanding poverty in all its complexity depends on excellent research.’ ■ Some examples of articles by SSI researchers: 1 •Mul, M.L., Kemerink, J.S., Vyagusa, N.F., Mshana, M.G. ,van der Zaag, P. and Makurira, H.

Researchers worked closely with farmers, which provided an excellent opportunity for mutual learning. From the farmers, scientists learned how local people innovate to adapt their agricultural systems to cope with environmental variability. At the same time, through working alongside scientists analyzing information and implementing measurement techniques, farmers saw their own farms from different perspectives, which helped them to come up with their own solutions. Synergy | 39 The cutting edge of scientific excellence Anyone who still believes that academic excellence is the preserve of fundamental scientific research, and that socially relevant science belongs on a lower academic plane, needs an intellectual reality check. With this one-off Magazine, Synergy: Teaming up scientific excellence and development relevance, we aim to show that the cooperation of scientific excellence and development relevance produces outcomes that are doubly rewarding. This magazine highlights the many and varied stories of what happens when fundamental and applied research meet tangible social needs – stories that range from the practicalities of fighting tuberculosis in Indonesia to using pure maths to warn about encroaching desertification. We can read about how efforts to improve the delivery of literacy education in Eritrea broke new ground in psycholinguistic theory. We can learn how a totally organic pesticide can protect crops better and more safely than chemical alternatives.And, if we can bear it, we can find out why a sustainable future depends on eating insects. These, and other stories, show that when the ingenuity of science fuses with the challenges of our everyday world, something out of the ordinary happens – and the outcome benefits us all.
