The Hadejia Jama’are River Basin Development Authority was created in 1986 along with ten other River Basin Development Authorities by the Federal Government of Nigeria. Presently the Authority has the largest functional irrigation schemes among the twelve River Basin Development Authorities in the country. The Authority covers an area of 45,000km2 (whole of Kano and Jigawa States, and about two-thirds of Bauchi State) with an irrigation development potential of about 212,000 hectares within the Vallies of Hadejia and Jama’are Rivers.
