Interventions aimed at increasing water availability for livelihood and domestic activities have great potential to improve various determinants of undernutrition, such as the quantity and diversity of foods consumed within the household, income generation, and women's empowerment. This review analyzes the existing evidence concerning the role of irrigation in improving nutrition and health outcomes. Most of the studies examined showed a positive effect of irrigation interventions on food security. However, existing evidence is still insufficient to draw broad conclusions, largely because nutrition is yet to be considered an explicit objective of irrigation development. Nutrition-sensitive irrigation programs are needed to help realize the full potential of irrigation interventions and avoid adverse impacts on human health and nutrition. (C) 2015 Elsevier B.V.
