Coping with Climate Shocks: Food Security in a Spatial Framework
Diogo Baptista

John A Spray

Ms. Filiz D Unsal
We develop a quantitative spatial general equilibrium model with heterogeneous house-holds and multiple locations to study households’ vulnerability to food insecurity from cli-mate shocks. In the model, households endogenously respond to negative climate shocks by drawing-down assets, importing food and temporarily migrating to earn additional income to ensure sufficient calories. Because these coping strategies are most effective when trade and migration costs are low, remote households are more vulnerable to climate shocks. Food insecure households are also more vulnerable, as their proximity to a subsistence requirement causes them to hold a smaller capital buffer and more aggressively dissave in response to shocks, at the expense of future consumption. We calibrate the model to 51 districts in Nepal and estimate the impact of historical climate shocks on food consumption and welfare. We estimate that, on an annual basis, floods, landslides, droughts and storms combined generated GDP losses of 2.3 percent, welfare losses of 3.3 percent for the average household and increased the rate of undernourishment by 2.8 percent. Undernourished households experience roughly 50 percent larger welfare losses and those in remote locations suffer welfare losses that are roughly two times larger than in less remote locations (5.9 vs 2.9 percent). In counterfactual simulations, we show the role of better access to migration and trade in building resilience to climate shocks.

Nepal: Selected Issues
International Monetary Fund. Asia and Pacific Dept
This Selected Issues paper utilizes a new macro-model capturing food insecurity, migration and trade in Nepal. It shows that low yields and remoteness explain a majority of the difference in prevalence of food insecurity across districts in Nepal; both climate shocks and persistent climate-change increase food insecurity and disproportionately harm the most vulnerable; and lower wages in migrant destinations would reduce remittances, increase food insecurity and lower welfare. The paper then presents and quantifies a number of potential policies to address these issues. The paper quantifies the impact of a number of policy options (cash transfers, better infrastructure, and improved agricultural productivity) to address food insecurity and climate change. In addition to climate shocks, persistent climate change will lower welfare, increase food insecurity, and migration. Given the model results show that agricultural productivity is a key determinant of food security, Nepal can learn from other countries policies including in agricultural extension, improved community water management techniques, and climate resilient agriculture in line with the National Adaptation Plan.

Nepal: Selected Issues
International Monetary Fund. Asia and Pacific Dept
This Selected Issues paper on Nepal measures the extent to which Nepal’s households change their expenditure patterns and labor supply in response to remittances, using the Nepal Household Risk and Vulnerability Survey—2016 and employing a propensity score matching method. This study provides stylized facts on migrant workers and remittance-recipient households (HH), and then analyzes the effect of remittances on HHs' expenditure patterns and labor supply. Reliance on remittances, both at the macro and household levels, makes Nepal highly vulnerable to shifts that could diminish remittance inflows. The slowdown in growth of remittances has been significant since 2016, owing to weak economic performance in major remittance-sending economies and less outward migration. This study also analyzes the effect of remittances on labor market participation of left behind household heads, using a propensity score matching method. The results show that remittances have supported greater consumption of productive goods (such as durable goods, education and health), without discouraging labor supply of remittance-receiving family members.

Nepal: Selected Issues and Statistical Appendix
International Monetary Fund
This Selected Issues paper examines the effect of political instability on economic growth in Nepal. It uses publicly available data on political economy variables for 167 countries worldwide from 1970–2004 to estimate the impact of political instability on growth. The findings reveal that Nepal has witnessed higher political instability compared with other countries in the region. The paper also presents the salient features of political instability and growth for Nepal and other South Asian countries, and the econometric estimates of growth regressions to measure the effect of political instability on economic growth.
