1) Entry Code & Bibliography:
Calzadilla et al. 2011
Calzadilla, A, Zhu, T, Rehdanz, T, Tol, RS & Ringler, C 2011, 'Economy- wide
impacts of climate change on agriculture – case study for adaptation strategies
in sub- Saharan Africa', in A Dinar & R Mendelsohn (eds), Handbook on climate
and agrarian change, Edward Elgar, UK, pp.169-203
2) Material Type
The chapter highlights the adverse effects of climate change on agriculture and
the implementable models suitable for reduction and adaptation strategies in
different scenarios.
3) Nature of the Material
The given material can be categorized as both, an analytical review and a paper
constituting empirical research. The chapter includes case studies in the Sub
Saharan Africa. Furthermore, it shows an overview of general equilibrium
models that can be used to assess the impact of climate change on agriculture
at the national and global levels.
4) Disciplinary Orientation
It is obvious from the title that the chapter has a multi-disciplinary outlook. Through
insights it can be found, the chapter provides information on climatic impacts on
agro-economy and uses statistical data, economic and agricultural sector models etc.
5) Background of the Material
The case study included in this chapter is based on the agricultural economy in subSaharan Africa. Even though agriculture is considered very important for subSaharan Africa, it has limited agricultural development due to specific agro- ecological
features, small farm sizes, poor access to services and knowledge, and low investment
in infrastructure and irrigation schemes. While Asia experienced a rapid increase in
food production and yields during the Green Revolution in the 1970s and early 1980s,
in sub- Saharan Africa per capita food production and yields have been stagnated ever
since. With suitable models and proper investment policies Sub-Saharan Africa has
the potential for expanding irrigation and increasing agricultural productivity. The
World Development Report 2008 points out that the new generation of betterdesigned irrigation projects and the large untapped water resources generate
opportunities to invest in irrigation in sub- Saharan Africa
6) Main Review
The chapter talks about different agricultural models namely The International Model
for Policy Analysis of Agricultural Commodities and Trade (IMPACT), Future
Agricultural Resources Model (FARM) and others for water use, management and
irrigation systems ,agro-economy, climate change analysis etc. It farther includes a
discussion improvising a comparison and linkage between the models IMPACT and
GTAP- W. The link of the two models allows for improved calibration and enhanced
insights into policy impacts. From the provided case study of Sub- Saharan Africa,
analyzing Scenario 1 (Expansion of Irrigated Agriculture) and Scenario 2
(Improvements in Agricultural Productivity) it can be said that the efficiency of the
two scenarios as adaptation measures to cope with climate change is measured by
changes in regional GDP. The author concludes the chapter by mentioning the
importance of analyzing the long- term impacts of extreme events on crop
productivity and human welfare especially the regions that are least likely to deal or
cope with the adverse effects of the climate change aftermath.
7) Relevance to ACAC Research Framework:
The research areas and works of ACAC includes agricultural management and
irrigation models which is relevant to the subject matter of this chapter
8) Significance for Future Research:
The agricultural models mentioned in the chapter in case of Sub- Saharan Africa can
be assumed suitable and implementable in context of Bangladesh as well, having
similarities in limitation of agricultural resources despite being an agro based
economy.
9) Key Words:
