USAID’s Water and Development Strategy (2013-2018) was released in May 2013 with the goal of saving lives and advancing development through improvements in water, sanitation and hygiene programs and through sound management and use of water for food security. The Multi-Sectoral Nutrition Strategy was released a year later in May 2014, with the goal of improving nutrition to save lives, build resilience, increase economic productivity and advance development. This implementation brief was initially released in complement to the existing Water and Development Strategy Implementation Field Guide, to USAID staff in January 2015 to facilitate and support programming decisions on WASH and Nutrition, a key theme in the Water and Development Strategy. The brief is being re-released to support similar programming in the context of the Multi-Sectoral Nutrition strategy. Other briefs in the Water and Development Strategy Implementation Briefs series currently available or in development will provide additional information to facilitate and support programming decisions on the following key themes related to the USAID Strategies: Agriculture Management, Sanitation, Water Quality, and Sustainability of WASH Services.
