On November 19, celebrate World Toilet Day 2020. This year’s theme—sustainable sanitation and climate change—explores the way flooding, drought, and rising sea levels can damage any part of a sanitation system, such as toilets, pipes, tanks and treatment plants, which leads to the spread of raw sewage. Sustainable sanitation systems keep untreated human waste out of the environment.
USAID prioritizes safely managed sanitation services that improve health outcomes and reduce pollution that comes from improper treatment and the spread of diseases. This entails a focus on not only containment, but also the emptying, transport, treatment, and safe disposal of waste. Any USAID investment in management of fecal waste must account for the final destination of the waste and take measures to ensure waste is not illegally dumped in the environment.
This issue features recent USAID sanitation publications as well as studies on COVID-19 and sanitation, sanitation financing, resource recovery, and other topics.
World Toilet Day 2020: Sustainable Sanitation and Climate Change – World Toilet Day is a United Nations Observance that celebrates toilets and raises awareness of the 4.2 billion people living without access to safely managed sanitation. The celebration day encourages action to tackle the global sanitation crisis and achieve Sustainable Development Goal 6: water and sanitation. The website provides a Toolkit, Social Media Resources, and campaign materials.
