On Monday, November 19, join USAID and its partners around the globe in celebrating World Toilet Day to help bring attention to the roughly 4.5 billion people without access to safely managed sanitation. Now in its 17th year, World Toilet Day (WTD) inspires action to tackle global sanitation challenges through improving sanitation facilities and services, strengthening the effectiveness and financial sustainability of wastewater management utilities, and raising public awareness about the health benefits of eliminating open defecation.
Increasing access to safe, sustainable sanitation is a key objective of USAID’s Water and Development Plan, as well as the broader U.S. Government Global Water Strategy. This issue of Water Currents highlights some of the USAID-funded research and activities that help to fulfill that goal, along with studies and resources on the WTD 2018 theme, nature-based sanitation solutions. The issue also includes recent sanitation-related reports and studies from IRC, Water and Sanitation for the Urban Poor, and others.
