"An economywide, multimarket model is constructed for Ghana and the effects of agricultural soil erosion on crop yields are explicitly modeled at the subnational regional level for eight main staple crops. The model is used to evaluate the aggregate economic costs of soil erosion by taking into account economywide linkages between production and consumption, across sectors and agricultural subsectors. To fill a gap in the literature regarding economic cost analysis of soil erosion, this paper also analyzes the poverty implications of land degradation.

Policy Analysis for Sustainable Land Management and Food Security in Ethiopia presents a bioeconomic model of this less- favored area in the Ethiopian highlands. The main reason for selecting this case study area is the unique availability of both biophysical and socioeconomic data covering a period of 15 to 20 years.The data provides a valuable opportunity to analyze the relationships between population pressure, poverty, and land degradation and to test policies for reducing vulnerability and improving sustainable management of the resource base....

Recent trends in agricultural growth and food security in Eastern and Central Africa (ECA) have been discouraging. With very low labor productivity, yields, and growth rates, agriculture is unable to keep up with population growth or achieve the type of pro-poor growth needed to reduce poverty dramatically.Yet agriculture accounts for about half of the region’s gross domestic product (GDP) and is the main source of livelihood for the majority of the population. Behind this gloomy picture, however, lies agriculture’s potential to be the engine for growth in ECA.

The 2014 Global Hunger Index (GHI) report—the ninth in an annual series—presents a multidimensional measure of national, regional, and global hunger. It shows that the world has made progress in reducing hunger since 1990, but still has far to go, with levels of hunger remaining “alarming” or “extremely alarming” in 16 countries. This year’s report focuses on a critical aspect of hunger that is often overlooked: hidden hunger. Also known as micronutrient deficiency, hidden hunger affects more than an estimated 2 billion people globally.

This 2012 Global Food Policy Report is the second in an annual series that provides an in-depth look at major food policy developments and events. Initiated in response to resurgent interest in food security, the series offers a yearly overview of the food policy developments that have contributed to or hindered progress in food and nutrition security. It reviews what happened in food policy and why, examines key challenges and opportunities, shares new evidence and knowledge, and highlights emerging issues.
