Climate change adaptation in agriculture: Ex ante analysis of promising and alternative crop technologies using DSSAT and IMPACT

Achieving and maintaining global food security is challenged by changes in population, income, and climate, among other drivers. Assessing these challenges and possible solutions over the coming decades requires a rigorous multidisciplinary approach. To answer this challenge, the International Food Policy Research Institute (IFPRI) has developed a system of linked simulation models of global agriculture to do long-run scenario analysis of the effects of climate change and various adaptation strategies. This system includes the core International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT), which is linked to water models (global hydrology, water basin management, and water stress on crops) and crop simulation models.Non-PRIFPRI1; CRP2; CRP7; A Ensuring Sustainable food production; A.1 Global Futures and Strategic ForesightEPTD; PIMCGIAR Research Program on Policies, Institutions, and Markets (PIM); CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS
