Dryland regions in Sub-Saharan Africa are home to one-half of the region’s population and three-quarters of its poor. Poor both in natural resources and in assets and income, the inhabitants of
drylands are highly vulnerable to droughts and other shocks. Despite a long history of interventions by governments, development agencies, and civil society organizations, there have been no
sustained large-scale successes towards improving the resilience of drylands dwellers. This paper describes the extent to which agricultural water management interventions in dryland regions of
Sub-Saharan Africa can enhance the resilience and improve the well-being of the people living in those regions, proposes what can realistically be done to promote improved agricultural water
management, and sets out how stakeholders can make those improvements. After reviewing the current status of irrigation and agricultural water management in the drylands, the authors discuss
technical, economic, and insitutional challenges to expanding irrigation. A model developed at the International Food Policy Research Institute is used to project the potential for irrigation
development in the Sahel Region and the Horn of Africa. The modeling results sow that irrigation development in the drylands can reduce vulnerability and improve the resilience of hundreds of
thousands of farming households, but rainfed agriculture will continue to dominate for the foreseeable future. Fortunately many soil and water conservation practices are available that can
improve the productivity and ensure the sustainability of rainfed cropping systems.The purpose of this paper is to demonstrate the potentially highly beneficial role of water and water
management in drylands agriculture in association with agronomic improvements, market growth, and infrastructure development, and to assess the technological and socioeconomic conditions and
institutional policy frameworks that can remove barriers to adoption and allow wide scale take-up of improved agricultural water management in dryland regions of sub-Saharan Africa.
