Effect of Climate Change on Food Production
Precipitation, Crops, and Food Insecure Regions
Precipitation Change
Change in Precipitation By the End of the 21st Century
Prioritizing Regions Food Security Impacts for 2030Criteria taken into account:
Importance of a crop to the region’s food-insecure population (HI)
Projected impact of climate change to a crop’s production

Discussion QuestionsWhat can be done to curb the influence of the
decrease in precipitation on food insecure regions?Is shifting planting/harvesting schedules enough?How will regions be affected that can no longer
grow staple crops?How will changing crops impact traditions and
customs in regions? Will the people be open to a new dietary supplement?
Developed countries will have less trouble adapting to a change in precipitation. Should developed regions aid the food insecure nations in building irrigation and researching more resilient crops?
