Impact of Climate Change on Agriculture - Factsheet on Latin America and the Caribbean

  • The crop modeling results indicate that climate change will have a negative effect on crop yields in Latin America and the Caribbean in 2050. The region will face average yield declines of up to 6.4 percent for rice, 3 percent for maize, 3 percent for soybean, and up to 6 percent for wheat.

  • In a no-climate change scenario, calorie availability in Latin America and the Caribbean would increase slightly between 2000 and 2050. With climate change, average food availability in the region will decrease by more than 300 calories per person, a decline of about 12 percent.

  • In a no-climate change scenario, the number of malnourished children in Latin America and the Caribbean will decline from about 7.7 to 5.0 million between 2000 and 2050. Climate change will eliminate much of this progress, resulting in 6.4 million malnourished children in 2050, 1.4 million more than in a no-climate change scenario.

  • To counteract the effects of climate change on nutrition, Latin America and the Caribbean require additional annual investments of about 1.3 billion USD, the majority of which should be used for agricultural research, irrigation efficiency and rural road improvements.
