Want to locate the Tiga Dam in Nigeria, Where is Tiga Dam Located in Nigeria?
Tiga Dam is located in the Northern part of Nigeria in Kano State. Tiga Dam was constructed in 1971–1974. It is a major reservoir on the Kano River, the main tributary of the Hadejia River. The dam was built during the administration of Governor Audu Bako in an attempt to improve food security through irrigation projects.
The Tiga Dam is a zoned filled earth dam located on River Kano, 70 km south of Kano City. It is one of the largest dams in the country and was designed and built between 1970 and 1974 with a capacity of 1.9 billion m3. The Dam sustains irrigated agriculture for thousands of hectares under the Kano River Irrigation Project and the Hadejia Valley Irrigation Project located in Kano and Jigawa States respectively.
In addition water supply to the formal irrigation schemes, water is also released from the dam into the river system all-year round for use by thousands of farmers along the river course in Kano, Jigawa, Yobe and Borno States for the production of a wide variety of food and cash crops. The Dam is also the major source of drinking water for Kano Metropolis as well as other towns and villages along the river course within the riparian States.
The dam was built during the administration of Governor Audu Bako in an attempt to improve food security through irrigation projects. The dam covers an area of 178 square kilometres (69 sq mi) with maximum capacity of nearly 2,000,000 cubic metres (71,000,000 cu ft). Water from the dam supplies the Kano River Irrigation Project as well as Kano City.
Several studies have shown that the dam has delivered negative economic value when its effect on downstream communities was taken into account. On completion of the dam the river flow downstream at Gashua in Yobe State fell by about 100,000,000 cubic metres (3.5×109 cu ft) per year due to upstream irrigation and by more than 50,000,000 cubic metres (1.8×109 cu ft) due to evaporation from the reservoir. A study published in 1999 concluded that farmers in the downstream floodplain had adapted their agriculture, helped by new technology, but the increased level of production might not be sustainable.
The Hadejia-Nguru wetlands further downstream have considerable economic and ecological importance. They are home to about one million people living by wet-season rice farming, agriculture at other seasons, fishing and cattle grazing by Fulani people. The dam has damaged the cycle, reducing fish catches and harvests of other wetland products.
In August 2009, Senator Ahmed Ibrahim Lawan of Yobe North, Chairman of the Senate Committee on Public Accounts, stated that the Tiga Dam had reduced water flow in the Kano River by about 50%. The senator was speaking in opposition to the proposed Kafin Zaki Dam on the Jama’are River, the other main tributary of the Yobe River. He said the Tiga and Challawa Dams had caused intense poverty, increased desert encroachment, migration and conflicts between arable farmers and herdsmen. He noted that the Yobe River no longer flows into Lake Chad.
