An overview of methods used to study the impact of climate change on agriculture in Central America and the Andean Region

Climate change is already affecting the global economy between catastrophic losses from extreme weather events to the subtler losses in agricultural productivity. In the decades to come, the effects of climate change will increase.

Climate change will be a significant challenge to farmers in Guatemala. In this report, we use climate models, crop models, and economic models to evaluate the impact of climate change at 50-kilometer resolution inside Guatemala and at the national level.

This discussion paper evaluates the likely impact of climate change on agriculture in Costa Rica out to 2050.

While agriculture represents only 7 percent of total GDP (World Bank 2014) for Peru, it is not an insignificant economic sector.

This paper explores the impact of climate change on agriculture in Nicaragua using biophysical models and a bioeconomic model. It also examines differences in projections of key climate models.

We use both biophysical and bioeconomic models to assess the impact of climate change on Honduran agriculture out to 2050.

This report finds that by 2050 the negative effect of climate change on agricultural productivity in El Salvador will be among the highest in the region.
