This report examines the impacts of climate change on agriculture and the costs of adaptation. It highlights that climate change will significantly affect crop yields, food prices, and overall food security, particularly in developing countries. The study uses two climate scenarios to project future conditions and assess the necessary investments to mitigate negative effects on human well-being. Key findings include substantial declines in crop yields, especially in South Asia, and increased food prices, which could reduce meat consumption and cereal consumption. The report also notes that climate change will lead to a decline in calorie availability and an increase in child malnutrition. To counteract these effects, the report recommends significant investments in agricultural productivity, rural infrastructure, and irrigation efficiency. It emphasizes the need for improved data collection and analysis, as well as the importance of community-based adaptation strategies. The analysis concludes that aggressive agricultural productivity investments of at least $7.1 to $7.3 billion per year are necessary to offset the negative impacts of climate change on children's health and well-being. The report also calls for increased funding for adaptation programs and the integration of agricultural adaptation into international climate negotiations.This report examines the impacts of climate change on agriculture and the costs of adaptation.
