Abstract
The impact of global climate change on the less developed countries is analyzed using archetype CGE-multimarket models for three economies representing the poor cereal importing nations of Africa, Asia, and Latin America. The objective is to predict the differential impact of climate change across continents on macroeconomic variables, sectoral responses, and household income and food consumption effects, particularly among the poorest. Results show that all these countries will lose and that their agricultural outputs will fall, but that Africa will be by far the most severely affected. Countervailing policies to mitigate negative effects should focus on the production of food crops in Africa and of export crops in Latin America and Asia.
