This paper uses both a global and local perspective to assess the impacts of climate change on the Yemeni
economy, agriculture, and household income and food security. The major impact channels of climate
change are through changing world food prices as a result of global food scarcities, long-term local yield
changes as a result of temperature and rainfall variations, and damages and losses of cropland, fruit trees,
livestock, and infrastructure as a result of natural disasters such as recurrent storms and floods. Moreover,
spatial variation in climate change impacts within Yemen means that such effects can vary across
subnational regions. We develop a recursive dynamic computable general equilibrium (DCGE) model
with six agroecological zones to capture linkages between climate change, production, and household
incomes. We also capture changes in per capita calorie consumption in response to changing household
expenditure for assessing changes in people’s hunger situation as a measure for food security. Given the
high uncertainty surrounding future global food prices and local yields, all simulations are run under two
global climate scenarios
