This study examines the impact of climate, urbanization, and population on water supply in Lagos State. Population baseline data used for this research were based on provisional census data of 1963, 1973, 1991, and 2006. Urbanization assessment were based on multi-temporal imageries from Landsat MSS, TM, NigeriaSat-1, and Landsat ETM+ for 1975, 1995, 2007, and 2015, respectively. Monthly temperature and rainfall data between 1960 and 2015 were collected from the Nigerian Meteorological Agency (NIMET), Oshodi, Lagos, Nigeria, and used for climatic assessment. Information on water production, demand, and supply for this study were gleaned from the Nigerian Bureau of Statistics (NBS), Lagos State Water Corporation reports of various years, and relevant literature on Lagos water supply and demand. The census data revealed that the population of Lagos State increased by about 525.9% between 1963 and 2006 and rose to about 754% in 2015 based on 3.4% growth rate. On the other hand, water demand increased from 172,088m3/d in 1963 to about 2,392,792m3/d in 2015 while water supply rose from about 97,377m3/d in 1963 to about 930,531m3/d in 2015. Urban land use/build up area increased from 230.8km2 in 1976 to 805.4km2 in 2015 while climatic records revealed that temperature and rainfall relatively increased by about 0.05080C and 0.0159mm respectively for 55 years. The study concludes that there will be more pressure on water as a result of population growth which will further impact the changing functionality in terms of socio-economic and infrastructural development of Lagos State in the near future.
