Abstract
The effect of rainfall variability on water supply in Ibadan South West L.G.A was investigated in this study. Data collected were analyzed using descriptive statistics, correlation and regression analysis. The result of the analysis shows that there is a weak positive relationship between annual rainfall received and the public water supply in the study area during the selected (2006-2020) years. The results obtained from the computation of correlation were used to test for the validity of the first hypothesis. It was discovered that water demand by each household is almost similar from zone to zone which shows that the people are with similar water needs with 52.92% of the population needing 401 to 600 liters of water per day while 10.48% consumes over 800 liters of water per day The result also shows that the calculated value (3.807) is greater than the tabulated value (2.167). Therefore we reject the null hypothesis which states that there is no relationship between rural water supply and rainfall variability in the study area to accept the alternative hypothesis which states that there is a relationship between rural water supply and rainfall variability in the study area confirming that water availability and water supply is vulnerable to climate change and rainfall variability. The study recommends that the people, civil society organizations, government as well as non-governmental organizations should rededicate their efforts of ameliorating the adverse effect of climatic change and rainfall variability on water supply through massive development of ground water sources and rain harvesting techniques.
