ANALYSIS OF THE IMPACTS OF CLIMATE CHANGE AND VARIABILITY ON WATER ACCESSIBILITY AND SUPPLY IN YAURI, KEBBI STATE, NIGERIA
The study examines the impacts of climate change and variability on water accessibility and supply in Yauri, Kebbi State. Both primary and secondary data were employed for the study. A total of 266 questionnaires were administered to the residents in the study area. Secondary data used include meteorological data (rainfall, minimum and maximum temperature and evaporation) from NIMET, Yauri for the period of31 years that spanned between 1 984 to 2014. Also data on quantity of water supplied from Yauri Waterworks were collected. The statistical technique! used include descriptive statistics, Pearson Product Moment Correlation, Multiple Regression Analysis and TrendAnalysis. The result from the descriptive statistics revealed that 49.8 of the respondents lack access to water. In the same vein, 38.4, 31.0 and 18.4 indicated that effects of dry season, climate change/variabilify and high temperature account for low water accessibility in the Study area respectively. Result from Pearson moment correlation revealed a strong positive relationship (0.76) between monthly rainfall and monthly water - supply at 0.05 significant levels. The result of multiple regression analysis with four explanatory variables has an R2 of 0.526 which confirmed that 52.6 of variation in water supply can be explained by climatic factors. Recommendations were made which include; curbing of climate change induced anthropogenic activities, effective water resources management and planning among others.
