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.

Water Supply Services

In some parts of Africa, rainfall variability has resulted in widespread droughts and floods, thus posing a substantial challenge to water availability in rural areas, especially drinking water. Therefore, due to increasing water demands, increases in the population, and economic development, water supply systems are under constant stress. One of the critical uncertainties surrounding the effects of rainfall variability in Africa is the significant impact that it imposes on rural water supply services. The present study analyzes the trends in annual and seasonal rainfall time series in the Wami River Basin to see if there have been any significant changes in the patterns during the period 1983–2017 and how they affect the access to water supply services in rural areas. The study analyzes the trends of rainfall series of three stations using simple regression, Mann–Kendal Test and Sen’s Slope Estimator. The water point mapping datasets were analyzed considering seasonal variation. The analysis showed a statistically significant positive trend in annual rainfall at Kongwa and March–April–May (MAM) seasonal rainfall at Dakawa. The maximum increase in annual rainfall occurred at Kongwa (5.3 mm year−1) and for MAM seasonal data at Dakawa (4.1 mm year−1). Water points were found to be significantly affected by seasonal changes, both in terms of availability and quality of water. There also exists a strong relationship between rural water services and seasons.

Ground electromagnetic profiling, using a Geonics EM34-3 instrument, has been employed to identify areas of high conductivity in a Precambrian basement complex terrain of Nigeria. Field examples, conducted as part of a rural water supply programme, are presented. They indicate that the apparent conductivities are generally lower than about 60 mmho m−1. Subsequent borehole drilling suggests a good correlation between high EM34 anomalies, deep weathering and high well yield (> 1 1 s−1). On the other hand, boreholes sited on conductivity lows penetrated a thinner regolith with relatively lower yields.

The paper reports the main findings of a study, designed to develop a better understanding of institutional variations in working with the demand responsive approach (DRA) in rural water supply in the state of Odisha in India. Data for the paper were collected from twelve village communities, where water is being supplied either through their community based institution or through the local government institution of the Gram Panchayat. The findings suggest that the two types of institutions performed differently in implementing the DRA. It depicted that the DRA under the broader rubric of institutional reforms in the water sector has failed to address the question of social inequality, and rather had reinforced and extended the already existing inequity of Indian society to access to safe and secure drinking water in rural areas. The study highlights that participation, cost recovery, full operation and management transfer may be an efficient proposition, but not sustainable in the long run without proper investment in institution building and support from the state, especially in provisioning of basic services like drinking water to rural poor.
