BRIEF ON THE TOUR TO KANO RIVER IRRIGATION SCHEME (KRIS), KANO STATE, NIGERIA
Kano River Irrigation Scheme (KRIS), is one of the largest and most successful irrigation schemes in the Nigeria. The Scheme (KRIS I) lies between latitudes 11 45’ and 12 05’ N and longitude 8 45’ and 9 05’ E about 30 km south east of Kano City.
The Tiga Dam is located on River Kano, 70km south of Kano City. It is one of the largest dams in the country and was designed and built between 1970 and 1974.
The Farmers: The involvement of farmers in the scheme management is dated since 1990s with the support of the International Water Management Institute (IWMI) and in 2000 by the French Embassy. More recently, the World Bank through the TRIMING Project carried out an elaborated farmer organization, strengthening and capacity building. Water Users Associations (WUAs) were formed, strengthened, organized and capacitated in all aspects of leadership and O&M activities. The KRIS serves over 35,000 farmers and provides their sources of livelihood for their families.
This dam is the cornerstone of water resources development in the Kano River Valley in Kano State and Hadejia River Valley in Jigawa State. The dam sustains irrigated agriculture for thousands of hectares in Kano River Irrigation Scheme (KRIS) and other small scale farmer irrigation along the river system.
The Dam is equipped with three outlets as follows:
- The main outlet is a 3.65m diameter conduit supplying a 2.2m diameter Howell Bunger regulating valve.
- 2Nos. 90cm diameter conduits with 60cm regulating valve.
The elevation of the scheme lies within 440masl, with minimum storage level of Tiga Dam, the main source of water for the scheme, at 506.50 meters, which provides a perfect setting for gravity irrigation.
