The populations, infrastructure and ecology of cities are at risk from the impacts of climate change which affect urban ventilation and cooling, urban drainage and flood risk and water resources. Built areas exert considerable influence over their local climate and environment, and urban populations are already facing a range of weather-related risks such as heat waves, water pollution and flooding. Although climate change is expected to compound these problems, building designers and spatial planners are responding through improved building design and layout of cities. There is also a need for weather data for testing future performance of urban drainage and water supply systems. Urban forestry and associated
Nigeria has abundant water resources. This natural endowment is evident in the yearly rainfall and large surface bodies of water-rivers, streams as well as abundant reservoirs of underground water. However, because of lack of good developmental policy, the rational use of the water resources still poses problems and challenges in most states of the country. For some time now these water problems have been left with the River Basin development authorities with little success, primarily because of lack of good management and best practices, despite huge sum of money spent. Although there are surplus surface and underground water resources within the Anambra basin, basic water supply for domestic and industrial use have been in very short supply for the teeming 5 million population despite the fact that government through international programmes like the Millennium Development Goals (MDGs), UNICEF, EU has done a lot to aid water supply. This paper is timely because of a recent introduction of a major regional water supply project earmarked to take off in Onitsha, the industrial and commercial hub of Anambra. It is expected that the quantity and quality of water would improve with this project to be financed by the government in urban areas of Onitsha, Awka and Nnewi. Published as well as unpublished secondary sources were used to present the access to drinking water in Anambra State. Reform efforts are currently going on in the state and a review of the reform reveals the effects of political and economic challenges on the existing strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
