Agriculture is vital to the economies of Sub-Saharan Africa: two-thirds of the region’s people depend on it for their livelihoods. Nevertheless, agricultural productivity in most of the region is stagnant or declining, in large part because of land degradation. Soil erosion and soil nutrient depletion degraded almost 70 percent of the region’s land between 1945 and 1990; 20 percent of total agricultural land has been severely degraded. If left unchecked, land degradation could seriously threaten the progress of economic growth and poverty reduction in Africa.

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....

The government of Uganda, with help from its development partners, is designing and implementing policies and strategies to address poverty, land degradation, and declining agricultural productivity. Land degradation, especially soil erosion and depletion of soil nutrients, is widespread in Uganda and contributes to declining productivity, which in turn increases poverty.

Land degradation poses daunting challenges to Niger and the country has designed several policies and strategies for combatting it. Building on work past studies, this study uses new satellite data which have higher resolution and run for longer time – thus capturing the longterm land management dynamics. This study also uses an improved cost of land degradation model which nets out benefits from land improvement as well analysing the impacts of land degradation on food and nutrition security.

Les sols sont vivants, indispensables à la vie, et presque non renouvelables. Ils sont pourtant assaillis par l’étalement urbain et des pratiques agricoles désastreuses. Sans oublier l’intrusion croissante de sociétés foncières spéculatives. Un rapport parlementaire alerte sur cette situation et appelle à une grande loi foncière.

Comprehensive yet concise report outlining the key challenges and projected demands in the global agricultural sector, from an energy-water-food nexus perspective.

Discusses the widely help conception that arid shrub-lands in Syria and elsewhere in West Asia and North Africa are degraded. A particular characteristic of such areas is a preponderance of unpalatable shrubs or a lack of overall ground cover with a rise in the associated risks of soil erosion.The article finds that:migrating pastoralists have been the scapegoats for this condition of the range.
