The MaMaSe Sustainable Water Initiative is aimed at improving water safety and security in the Mara River Basin to support structural poverty reduction, sustainable economic growth and conservation of the basin's ecosystems. In this four year programme the people and institutions in the basin will be supported in a process of structural change, promoting water-wise economic development that lifts people out of poverty and sets them on a sustainable path to improved well being and self-reliance.

The Initiative, which is financially supported by the Netherlands Embassy in Nairobi, Kenya, consists of a broad-based public private partnership including international and Kenyan government agencies, civil society, private sector, NGOs, and knowledge institutions. It is led by UNESCO-IHE together with WWF Kenya.
