Increase in temperature: • Reduction of photosynthesis • Outer shell sticking to bean, preventing ripening • Changes in pest and disease incidents • Droughts erosion loss of soil fertility Change in precipitations patterns / extreme weather events: • Damages the beans and affects growth • Irregular precipitation patterns during the harvest season makes the drying process more difficult, altering the quality of the product • Strong precipitation landslides loss of plants and soil • Strong winds loss of plants or falling of flowers reduced harvest • Changes in flowering / irregular flowering Source: Various studies of CIAT and CATIE, AdapCC 2010 What are predicted changes for Brazil? Temperature Increases by > 3°Cin southern Brazil expected by 2050 For southern South America above 4°C in summer and 2 to 5°C in winter expected by 2071 - 2100 Due to rising temperatures: increased evapotranspiration water deficiency in south and southeast Brazil Hot days / nights More short-term temperature extremes expected, increasing number of hot days and nights Precipitation Increase of rainfall of above 20% in Southeast in form of more intense and more frequent extreme events expected by 2071 – 2100 Source: 4th AR IPCC 2007; CREAS 2009 What are the consequences for Brazilian agriculture? • By 2050: 50% of currently suitable area for agriculture will be affected by desertification and salinization (IPCC 4 AR 2007) th • Benefits: reduced frost risk in southern and southeast regions (Pinto, Assad) Current suitable coffee growing zones Source: Pinto & Assad 2008 Predicted changes in suitability: Optimistic outlook Current suitable areas Source: Pinto & Assad 2008 Optimistic outlook SRES B2 until 2050 (-18.3%) and 2070 (-27.39%) Predicted changes in suitability: Pessimistic outlook Current suitable areas Source: Pinto & Assad 2008 Pessimistic outlook SRES A2 until 2050 (-17.1%) and 2070 (-33%) What are the consequences for Brazilian coffee production? Predictions by EMBRAPA and UNICAMP: • By 2050 loss of 18.3% of total land suitable for coffee; by 2070 loss of 27.39% • Potential losses of at least R$ 1.7 billion, R$ 2.57 billion respectively (based on 2006 production of 2.5 million tonnes worth R$ 9.3 billion) • Arabica coffee hit hardest: likely loss of suitable area by up to 33% in São Paolo and Minas Gerais due to water shortages or excessive heat • Increasing suitability for coffee production in the south due to reduced frost risk because of rising temperature • Potential increase in suitability for coffee production in Paraná, Santa Catarina, Rio Grande do Sul • Despite the suitability increase in the south, a loss of total production area is expected THANK YOU FOR YOUR ATTENTION Climate Change Adaptation and Adaptation Options in Coffee An overview Climate Change Adapation and Adaptation Options in Coffee Key Questions: • What are responses to climate change? • What does climate change adaptation mean? • What are climate vulnerabilities? • How can coffee producers adapt to climate change? • Are there practical examples to learn from? • What are relevant terms and definitions? What are responses to climate change? Climate Change Adaptation Impacts Responses What is climate change adaptation? Definition: Adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm or exploits beneficial opportunities. Various types of adaptation can be distinguished, including anticipatory and reactive adaptation, private and public adaptation, and autonomous and planned adaptation (IPCC TAR, 2001 a) Action of people (e.g. coffee farmers) that minimizes negative impacts of climate change or utilizes opportunities. What are climate vulnerabilities? Vulnerabilities in the production system: • Inadequate management of the farm / of the agro-forestry system • Old plants • Poor soil fertility • Inefficient management of natural resources • High deforestation rate affecting local ecosystems Vulnerabilities of producers: • High dependence on one cash crop / one source of income • Lack of access to information / education / capacity • Lack of access to finance How can coffee producers adapt to climate change? Coffee producers have mainly three options to adapt: 1. Adapting their production system 2. Adapting their plants 3. Enhancing their framework conditions How can coffee producers adapt to climate change? Examples of adaptation options: • Diversification of crops and income • Good agricultural practices (shade mgmt / pruning / pest mgmt / soil mgmt) • New technologies suitable for coffee drying (e.g. solar dryers) • Maintenance and expansion of forest cover • Efficient management of natural resources / efficient energy use (improved kitchen stoves, renewable energy) • Capacity building for promoter farmers and producers • Conservation of genetic diversity / species resistant to droughts • Access to climate information, credit, crop insurance • Farmer organizations What are recommendations for Brazil? The needs for adaptation differ from production site to production site. However, based on the projections for Brazil C&C recommends the following: Enhancing framework conditions Relevance Data collection: precipitation and temperature Having accurate local data on precipitation and on temperature helps to monitor changes in the microclimate and to predict future changes; it creates awareness on changes already taking place What are recommendations for Brazil? Adaptation of the Relevance production system Soil moisture retention by mulching Due to increasing temperature and evapotranspiration an emphasis will need to be put on the conservation of soil moisture Wind breaks To protect the coffee plots better against strong winds and extreme events Water harvesting As water shortage will be a challenge in especially São Paolo and Minas Gerais, water harvesting will help to relieve water stress Conservation of riparian areas In areas with increased rainfall and more extreme events well conserved riparian areas can support flood prevention; at the same time these can prevent high evapotranspiration rates Barriers to channel surface runoff More extreme weather events and an increase in rainfall in some areas will lead to excess water which should be channelled through the plot as to avoid water erosion and land degradation What are recommendations for Brazil? Adaptation of the plant Relevance Use of gypsum The gypsum will facilitate deeper growth of the roots, therefore nutrients and water down below can be reached, which will be important in areas with reduced rainfall and increased evapotranspiration Improved (i.e. deeper) polythene bags for seedlings This will also facilitate longer roots / deeper root growth before planting the seedlings (see above) Are there practical examples to learn from? Yes, there have been some pilot initiatives on climate change adaptation with coffee smallholders. One example is the project “Adaptation for Smallholders to Climate Change – AdapCC”: • • • • • Development Partnership between Cafédirect plc and GIZ Duration of three years: 04/2007 to 02/2010 3 pilots in coffee: Mexico, Peru, Nicaragua 1 pilot in tea: Kenya www.adapcc.org Practical example: AdapCC pilot Peru Climate Variability Prolonged droughts leading to more pest incidents Strong winds Cold fronts and fog http://www.adapcc.o rg/en/peru.htm Vulnerability High deforestation rate Degraded areas / landslides Poor pest and shade management Poor soil fertility due to poor agricultural practices Lack of investments in capacity building and infrastructure Adaptation Strategy Capacity building and technical assistance on good agricultural practices and climate change adaptation Reforestation program in the upper water catchment area and within the coffee plots What are relevant terms and definitions regarding adaptation? Exposure: • The degree of climate stress upon a particular unit (e.g. farm) in a defined area Sensitivity: • The degree to which a system is affected by, or responsive, to climate stimuli Vulnerability: • Factors which make a system (e.g. coffee production) susceptible to negative impacts of climate change Adaptive capacity: • The ability to adjust to climate stimuli Resilience: • The capacity of a system to rebound or recover from a climate stimulus THANK YOU FOR YOUR ATTENTION Climate Change Mitigation An overview Climate change mitigation Key Questions: • What are responses to climate change? • What is climate change mitigation? • Which greenhouse gases exist in agriculture? • Where do we cause emissions? • What are greenhouse gas pools and sources? • How can coffee producers mitigate climate change? • What are important terms and definitions? What are responses to climate change? Climate Change Impacts Responses Causes (GHG) Mitigation What is climate change mitigation? Definition: Climate change mitigation is action to decrease the intensity of radiative forcing* in order to reduce the potential effects of global warming (IPCC TAR, 2001) * Radiative forcing: the change in net difference between the incoming radiation energy and the outgoing radiation energy in a given climate system; measured in watts per square meter (IPCC TAR, 2001) Activities that reduce, prevent or remove greenhouse gases and therefore reduce climate change.
