The World Bank began a project in 1983 that involved installing 15,000 of low-cost shallow tube well technology combined with small engine-driven water pumps, a new technology that soon acquired the name "fadama irrigation". Fadamas – the hausa name for irrigable land – are flood plains and low-lying areas underlined by shallow aquifers, found along Nigeria’s river systems.  In 1992 the Bank prepared a new project which would construct about 50,000 shallow tube wells in Nigeria, would privatize drilling, simplify drilling technology for shallow tube wells, conduct aquifer studies and upgrade irrigation technologies. The irrigation projects aim at increasing crop production through a coordinated approach to rural development.  The main elements are improved technology and the means to get it to farmers, increased supplies of farming inputs especially fertilizer, and extensive infrastructure improvements, especially rural roads and water supplies.
