Water is essential to health and food production. Globally, nearly 2.1 billion people lack access to safe drinking water in their homes and about 4.4  billion lack access to proper sanitation, putting them at risk of disease. Coupled with poor hygiene, the lack of adequate water and sanitation is a leading cause of disease and death worldwide. Food production is the largest consumer of water, and also represents the largest unknown factor of future water use as the world population continues to increase. Global population growth projections of 2 to 3 billion people over the next 40 years, combined with changing diets, are expected to increase food demand substantially by 2050.

Our Water and Development Strategy steers USAID’s water programs toward key themes consistent with two of the most important ways we rely on water: water for health and water for food. It is our hope that improvements in WASH programs, and sound management and use of water for food security will save lives and advance development. That’s why we are committed to integrating a focus on water across our agriculture and health work by:
