A climate change mainly to explore the various regions of crop production to adjust the priority of the corresponding studies have shown that in South Asia and southern Africa in the next two decades if not for agriculture to adjust some of their crop yields will be rocked, and the impact of global human food supply. The study of 20 global climate models (global climate model, GCM, also general circulation model) forecast in 2030 the climate variables (temperature and rainfall) and then into the crop as a statistical model (statistical crop model), the forecast 20 years later, the crop yield.
Lobell, who calculated the 12 regional daily famine crop importance (hunger importance, HI). This indicator for the number of undernourished people in the region with the crop in the daily dietary intake rate of the product, it can reflect the local people's dependence on the crop. The researchers of the indicators and crop production is forecast to determine the conditions that should give priority to agriculture and adaptation areas.
Theoretically, these areas, agricultural systems can be improved seeds, better fertilizer, land use and control to improve the situation. Researcher believes that the recent World Bank investment in agriculture more money, Rockefeller and Gates Foundation is committed to improving Africa's seed systems, for agriculture due to climate change should be specific help.
