IWaSP’s vision is to provide powerful solutions for water security, while its mission is to inspire joint action. IWaSP is an international water security programme which combines global best practices in water stewardship with local know-how. The innovative six-year programme (2013-2018) facilitates partnerships between the public sector, the private sector and civil society. It addresses shared water risks on a catchment scale, while improving stakeholders’ use and management of water and building their capacity to develop their own solutions. The programme is currently active in seven countries: Kenya, Uganda, Tanzania, Zambia and South Africa on the African continent and Grenada and Saint Lucia in the Caribbean. IWaSP is receiving a growing demand and expansion into further countries is planned. IWaSP enables partners to adopt a comprehensive and cost-effective approach to managing water risks for people, businesses and ecosystems. Typical results include pollution reduction, improved access to water, increased water storage, improved water infrastructure, rehabilitated ecosystems, strengthened water governance, improved catchment specific relationships of key actors and enhanced collaborative action.
