Water Currents: Sanitation Topics

Because sanitation uptake continues to lag behind drinking water in terms of access gains, development practitioners are taking a closer look at what has and hasn’t worked in the past, modifying approaches that delivered early wins but not sustainable gains in coverage, and making sanitation financing a priority.
 
USAID is doing its part to fill evidence gaps related to sanitation and behavior change and support the reduction of open defecation and movement of communities up the sanitation ladder by identifying, researching, and sharing best practices for the delivery of water, sanitation, and hygiene (WASH) services and sustained behavior change. The Agency has also made it a priority to close financing gaps to help countries achieve universal access to WASH services through sustainable and creditworthy business models, increased public funding, and expanded market finance for infrastructure investment.
 
This issue contains recent studies and resources on a variety of sanitation-related topics such as market-based sanitation, community-led total sanitation, fecal sludge management, sanitation financing, and others.

The results highlight the need to consider the social context when planning and implementing sanitation campaigns.

CLTS Knowledge Hub – Community-Led Total Sanitation. The CLTS website aims to be a global hub for CLTS, connecting the network of practitioners, communities, NGOs, agencies, researchers, governments, donors, and others involved or interested in CLTS. The knowledge hub publishes Frontiers of CLTS: Innovations and Insights and each issue focuses on a specific CLTS topic.
