Across the globe, 2,000 children die every day from diarrheal diseases caused by unsafe water and poor sanitation. Over the course of four years, the project supported by the Gates Foundation will improve sanitation in local government areas across three states of Africa's largest popluated country Nigeria, where 103 million people have to defecate in the open or have an "unimproved" or shared latrine. It will bring about open defecation-free (ODF) status in numerous communities, and bringing affordable and sustainable sanitation services to thousands of people. The project will build on WaterAid's years of experience of applying and adapting the community-led total sanitation (CLTS) approach in Nigeria. CLTS is an innovative methodology for mobilizing communities to completely eliminate open defecation. "The Gates Foundation has once again invested in improving the lives of millions of the world's poorest people. We are thrilled that they have decided to support our work in Nigeria," said Dr. David Winder, Chief Executive of WaterAid in America. WaterAid has worked in Nigeria since 1995, assisting with addressing the huge need for water and sanitation. WaterAid works in seven local areas, in partnership with established non-governmental organizations (NGOs) and state and local governments, according to each area's needs.
