The Ewaso Ng’iro North Development Authority (ENNDA) was established in 1989 through an Act of Parliament (CAP 448 of the Laws of Kenya) with a mandate to plan, coordinate, and implement integrated development projects and programs across the expansive Ewaso Ng’iro North River Basin. The basin covers over 209,000 km2, which represents about 36% of Kenya’s total land area. It spans across 10 counties – Wajir, Mandera, Laikipia, Isiolo, Marsabit, Samburu, Nyeri, Nyandarua, Meru, and parts of Garissa – with an estimated population of over 4 million people.

Since its inception, ENNDA has focused on sustainable and integrated development initiatives across several key sectors including water resource development, livestock production, agriculture, forestry and wildlife conservation, infrastructure development, environmental management, and peacebuilding. The core functions involve conducting feasibility studies, developing water infrastructure such as dams, boreholes and water pans, setting up farmer irrigation schemes, promoting drought-resilient crop farming and livestock keeping practices, supporting value-chains development, and undertaking catchment conservation and rehabilitation programs among others.
