This dissertation’s three essays explore the determinants of food insecurity for rural farm households, the influence of rainfall variability and long-run changes in rainfall levels on the migration decisions of working-age household heads, and the distributional impacts in core and periphery regions of food assistance to households in the hinterland.

The first essay examines how socio-economic characteristics of households, local conditions, and public programs are associated with the probability that a farm household in rural Malawi is food insecure. The statistical analysis uses nationally representative data for 7,965 randomly-selected households interviewed during 2004/05 for the second Malawi Integrated Household Survey (IHS-2). Regressions are estimated separately for households in the north, center, and south of Malawi to account for spatial heterogeneity. Results of a Probit regression model reveal that households are less likely to be food insecure if they have more cultivated land per capita, receive agricultural field assistance, reside in a community with an irrigation scheme, and are headed by an individual with a high school degree. Factors that positively correlate with a household’s food insecurity are number of household members and distance to markets.
