This working paper analyses the effect climate change is expected to have on agricultural productivity, caloric consumption, and vulnerability to food insecurity of household agricultural producers in Paraguay. Our results suggest that increasing temperatures and reduced precipitation will reduce agricultural productivity and caloric consumption, and increase vulnerability to food insecurity. Specifically, a 1 percent increase in average maximum temperatures is associated with a 5 percent reduction in agricultural productivity. A 5 percent reduction in agricultural productivity translates into nearly a 1 percent reduction in caloric consumption. Vulnerability to food insecurity in Paraguay is expected to increase by 28 percentage points by 2100 due to climate change, increasing fastest in areas where temperatures are increasing and rainfall is diminishing. We explore a number of interventions that policy makers can pursue to limit the impact of climate change on food insecurity.
