The Bakolori Dam is in Sokoto State in the Northwest of Nigeria, completed in 1978 and its reservoir filled by 1981. It is a major reservoir on the Sokoto River, a tributary of the Rima River, which in turn feeds the Niger River. Water from the dam supplies the Bakolori Irrigation Project. The dam has a capacity of 450 million cubic meters, with a reservoir covering 8,000 hectares extending upstream. The dam construction project displaced many peasant farmers without providing alternative land or financial compensation. Many people died in protests over their loss of livelihood. The project has become known as a classic example of development failure. ==Background== The Sokoto River runs through the semi-arid Sudan Savannah zone of northern Nigeria. Annual rainfall is unpredictable, ranging from 500 mm to 1,300 mm per year during the June–September period. Before construction of the dam, about 50,000 farmers in the Sokoto River floodplain practiced intensive recession farming, growing rice and sorghum in the wet season and vegetable crops such as onions, garlic and tomatoes in the dry season.〔 Many farmers used the Shadoof practice of lifting water from the river to pour into irrigation channels or ponds. Women in purdah do not usually work the field but do have ownership rights and assist in processing. Women who are not under seclusion are active in farming.〔 Often the land was owned communally without formal records of ownership.〔 Farmers in the area, living at subsistence levels, were more concerned with avoiding risk than maximizing profit. The area is subject to periodic droughts, and the desire for a stable water supply was one of the motives for constructing the dam.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bakolori Dam」の詳細全文を読む スポンサード リンク
