When politicians fail to agree, very often it is the poorest who suffer most. More than 25 million additional children could go hungry through the failure of Copenhagen, says Gerald C. Nelson of the International Food Policy Research Institute. As crop yields decline, the calories available per p...

The perfect storm: food security and nutrition under climate change
Recent studies assessing plausible futures for agricultural markets and global food security have had contradictory outcomes. To advance our understanding of the sources of the differences, 10 global economic models that produce long-term scenarios were asked to compare a reference scenario with ...

Why do global long-term scenarios for agriculture differ? An overview of the AgMIP Global Economic Model Intercomparison
Climate change is expected to impact global food supply and food security by affecting growing conditions for agricultural production. Process-based dynamic growth models are important tools to estimate crop yields based on minimum inputs of climate, soil, crop management, and crop cultivar param...

Baseline simulation for global wheat production with CIMMYTmega-environment specific cultivars
The projected changes in planted area, yield per area, net exports/imports and prices for five major agricultural crops in South Africa were simulated using the projections of four Global Circulation Models (GCMs) under three socio-economic scenarios. The GCM projections show consistent strong wa...
Understanding the capacity of agricultural systems to feed the world population under climate change requires projecting future food demand. This article reviews demand modeling approaches from 10 global economic models participating in the Agricultural Model Intercomparison and Improvement Proje...

The future of food demand: understanding differences in global economic models
The first decade of the 21st century has brought harbingers of a troubled future for global food security. The food-price spike of 2008 led to food riots and political change in several countries. In 2010, the excessive heat and drought in Russia that led to wildfires and a grain embargo, as well...

Food security, farming, and climate change to 2050: challenges to 2050 and beyond
Agriculture and food security are key sectors for intervention under climate change. Agricultural production is highly vulnerable even to 2C (low-end) predictions for global mean temperatures in 2100, with major implications for rural poverty and for both rural and urban food security. Agricultur...
