The most recent (2010–2011) drought in the arid and semiarid lowlands (ASAL) of the Horn of Africa has rendered over 13 million people in need of food, and caused a devastating famine in southern Somalia. The drought has also raised concerns that pastoralist livelihoods in this region are...

Recent droughts in the Horn of Africa have again raised concerns over the viability of pastoralism. Vulnerability to drought, arguably increasing on the back of climate change and population pressures, provides a compelling justification for encouraging economic diversification. It is less...

The most recent (2010-211) drought in the arid and semiarid lowlands (ASAL) of the Horn of Africa has rendered over 13 million people in need of food, and caused a devastating famine in southern Somalia. The drought has also raised concerns that pastoralist livelihoods in this region are no...

Highland Ethiopia is one of the most densely populated regions of Africa and has long been associated with both Malthusian disasters and Boserupian agricultural intensification. This paper explores the race between these two countervailing forces, with the goal of inform two important policy...

Large gaps exist in our knowledge of the current geographic distribution and spatial patterns of performance of crops, and these gaps are unlikely to be filled. In addition, even the spatial scale of many sub-national statistical reporting units remains too coarse to capture patterns of spatial...

Despite the rise of targeted input subsidy programs in Africa over the last decade, several questions remain as to whether low and variable soil fertility, frequent drought, and high fertilizer prices render fertilizer unprofitable for large subpopulations of African farmers. To examine these...

This paper presents an approach of combining biophysical, social, and economic factors for spatially explicit assessment of potential future risks of food insecurity at a global scale over the period of 2000--2020 under a certain scenario. In doing that, two indicators, namely per capita food...

We describe a new crop allocation model that adds further methodological and data enhancements to the available crop downscaling modeling. The model comprises the estimates of crop area, yield and production for 20 major crops under four rainfed and irrigated production systems across a global...
