Abstract: The effects of climate change on irrigation activities in the Benin-Owena River Basin (BORB), southwestern Nigeria, were investigated, using rainfall and temperature data from 1961 to 2000 with irrigation data from 1990-2000.. Climate records showed a large variation in annual rainfall between 1961-1980. The rainfall variation between 1980-2000 was less pronounced, and rainfall was much lower. The period 1982-1986 exhibited the greatest downward trend in rainfall. The decadal range of temperature showed a gradual warming of the environment. Increasing temperatures and decreasing rainfall, coupled with an increasing population, led farmers and policy makers in Nigeria to embark on massive irrigation activities from the 1990s to 2000. Farm productivity levels and irrigations activities in Edo State are discussed
