    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 Geleta
    A 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.

    Wheat Facts and Futures 2009
    (CIMMYT, 2009) Dixon, J.; Braun, H.J.; Kosina, P.; Crouch, J.H.
    For nearly half a century, the international wheat breeding system has delivered improved high yielding varieties of wheat that created (along with rice) the Green Revolution and underpinned strong growth in wheat productivity in irrigated and rainfed, developed and underdeveloped, regions. Future priorities for breeding and complementary sciences will still include yield but will also diversify in response to changing market demands and growing environments, particulary in developing countries. It is argued that in the coming decades research on wheat quality characteristics will become increasingly important to plant breeders, whose work will be supported by the development of markers and advanced tools from molecular biology. Breeders will have to contend with increased heat stress and variability stemming from climate change, which is expected to create regional winners, as the northern high latitudes grow warmer and moister, and losers, as the sub-tropics and tropics increasingly suffer from heat stress and drought. Yield response of improved varieties in farmers’ fields depends to a very great degree on sustainable systems management, which also is essential to reverse the ongoing degradation of agricultural resources. Finally, the importance of expanding the systems lens from farmers to policy makers, and of linking farmers, commerce, science, and policy is illustrated for the rice-wheat farming systems of South Asia.

    International Symposium on Wheat Yield Potential: Challenges to International Wheat Breeding
    (CIMMYT, 2008) Reynolds, M.P.; Pietragalla, J.; Braun, H.J.
    Like many other patterns, investment in research is often cyclical. International centers like CIMMYT have focused substantial resources on biotic and abiotic stresses for about two decades now, but raising total productivity is also back on the development agenda. There are a number of reasons for this, among them sharp rises in the price of staple foods as well as the manifestation of detrimental effects of climate change on productivity. Those factors threaten not only the livelihoods of resource-poor people but food security at a broader level, as highlighted by the World Bank’s recent World Development Report. CIMMYT has an unsurpassed record when it comes to raising crop yields from the days of the Green Revolution; as can be seen from the comprehensive scope of this new publication, our Global Wheat Program is back in the game. The book consists of proceedings of a week-long consultation of experts and leaders held in 2006 and representing all major wheat producing countries worldwide. It encompasses their ideas on how, through internationally coordinated collaborative research, proven technologies of the past can be married with new tools and approaches to meet demand for the world’s number one staple crop: wheat.
