Land degradation and poverty

Abstract

Land is one of the few productive assets owned by the rural poor, and almost all such households engage in some form of agriculture. Over 2000–2010 the rural poor on degrading agricultural land increased in low-income countries and in sub-Saharan Africa and South Asia. Although degradation threatens the livelihoods of the poor, this interaction is complex and conditioned by key economic, social and environmental factors. These factors also limit the poverty-reducing impacts of economic growth and economy-wide reforms. A comprehensive development strategy requires investments that improve the livelihoods of affected populations and regions, and facilitates outmigration in severely impacted areas.
