Progress and Challenges in Global Food Security

Article excerpt

Global food security-when people have access to at least 2,100 calories per day-has improved over the past 15 years, but countries still face challenges and there is still a need for improvement. ERS researchers recently analyzed the factors that led to past progress and highlighted emerging challenges and issues to feed 9 billion people in the world by 2050. Two key drivers of past improvements in food security are increased agricultural production and trade. For most of the countries studied, domestic production supplies most of the staple foods that people eat. Increases in production and agricultural productivity-producing the same or more output with fewer inputs like fertilizer or land-have improved food security. On average, the faster the growth in agricultural productivity, the greater the reduction in food insecurity.

In countries where climate or lack of land or water resources limits the potential for local production, food imports have played an important complementary role. Across all regions, food aid has decreased as a share of total cereal grain imports, with commercial food imports becoming more important to developing countries. In turn, these countries are becoming more significant in the global trading system as their imports rise. Growing income and increased urbanization also create new opportunities for future trade.
