Climatic change impacts on underground water resources development in Edo State were investigated using information on rainfall, temperature and evaporation of Benin City from (1961-2000) and information on borehole records of static and dynamic water levels in the different geological formations throughout Edo State. Results showed that in Benin City, temperature and evaporation have been on the increase during the past forty years while rainfall totals have been fluctuating in the downward trend. There has been a corresponding fluctuation in the static and dynamic water levels as well as the depth of aquifers in the different geological formations in Edo State. There is significant relationship between rainfall and temperature at 0.05, temperature and evaporation at 0.05 and rainfall, dynamic and static water levels and depth of aquifer at 0.0l. It was concluded that in the Benin-Owena River Basin, climate change has impacted on the hydrologic performance of the groundwater resources. © EuroJournals Publishing, Inc. 2011.
