Remote Sensing Based Approach to Enhance Food Security in the Greater Horn of Africa

Abstract

Greater Horn of Africa (GHA), one of the most food-insecure regions in the world, faces acute food insecurity with catastrophic consequences whenever a drought occurs. With climate change impacts and high population growth rate projected to exacerbate the food insecurity situation of the region, this thesis examined agricultural drought and groundwater exploitation (irrigated) related issues to enhance food security. The thesis identified several suitable agricultural drought indicators and explored groundwater irrigation potential for several regions.
