- Rural transformation and the future of cereal-based agri-food systems(Elsevier, 2020) Kruseman, G.; Mottaleb, K.A.; Fantaye, K.T.; Bairagi, S.; Robertson, R.; Mandiaye, D.; Frija, A.; Gbegbelegbe, S.D.; Alene, A.D.; Prager, S.D.
Publication - Potential impact of climate change trends on wheat production and mitigation strategies in Afghanistan(Canadian Center of Science and Education, 2015) Sharma, R.; Sonder, K.; Gbegbelegbe, S.D.Climate change is here and continues unabated. It is expected to affect different biological processes differently. Afghanistan has a varied climate profile and depends heavily on wheat, the staple food of its 30 million people. The irrigated wheat occupying about 1.35 million hectare and contributes major chunk of wheat to national granaries compared to rainfed wheat which is more opportunistic with an unpredictable and uncertain share in national harvest. Previous decades have already seen a reduction of up to 100 mm wheat season rainfall and more reductions are estimated by 2050. Also, wheat which is a cool season crop and is also estimated to face higher temperatures by up to 5 degree Celsius across several provinces in the country. The study predicts variable impact of the estimated changes on the productivity of irrigated and rainfed wheat in Afghanistan.
Publication - The potential for wheat production in Africa: analysis of biophysical suitability and economic profitability(CIMMYT, 2013) Asfaw Negassa; Shiferaw, B.; Koo, J.; Sonder, K.; Smale, M.; Braun, H.J.; Gbegbelegbe, S.D.; Zhe Guo; Hodson, D.P.; Wood, S.; Payne, T.S.; Abeyo Bekele GeletaA key staple in Africa, wheat is increasingly in demand in sub-Saharan Africa as a result of income growth and rapid urbanization, but sub-Saharan countries and Africa as a whole respectively produce only about 30% and 40% of their domestic requirements, causing a heavy dependence on imports and making the region highly vulnerable to global market and supply shocks. Conducted jointly by CIMMYT and IFPRI for 12 sub-Saharan African countries, this study used geographic information systems, simulation models, and economic analyses to conclude that the countries are using less than 10% of their potential for profitable wheat production. Unlocking that potential will require changes in attitudes, policy and donor support for adapting farming systems, empowering African farmers, and developing value chains for seeds, input supply, and output markets.
