It examines the socioeconomic effects of eutrophication in rivers of rural communities, Imo, Nigeria
Cultural Eutrophication of recent has been on the increase in Rivers and water bodies in Nigeria. In rural areas, observation shows that deforestation, increased siltation and Landuse around Riverine communities predominantly for farmland purpose are common hence, the high level of Phosphate and Nitrogen from runoffs during the rainy season. Aquatic lives are adversely affected and the aesthetic quality of the water for recreational activities like Swimming and Picnic are reduced. This paper reveals how man’s activities in trying to make a living can become inimical to the ecosystem thus, making life uncomfortable for him. The paper went further to suggest that Agricultural activities can be properly practiced so as not to be burden on the social economic life of the people who depends also on the waterbodies for other activities. Personal observation and photographing of the Rivers were carried out. A structured questionnaire of 160 respondents was sampled 40 each in the four villages of Umueleke, Umueze1, Umueze11 and Umunuakanu-Ama in Ehime Mbano Local Government Area, Imo State for the study. Data obtained were analysed using descriptive statistics. Tables, percentages and bar graphs were also employed for the analysis. Finding shows that there is intense reduction in the use of river water for drinking, domestic and recreational purposes. Fishing as an occupation is also on the decline as the rivers are adversely affected. However, the author used questionnaire tool of merely 40 per village which may give a wider perception and outcome if the no of questionnaire were more. Increase agricultural practice and Land conservation should be encouraged. The federal ministry of Environment should make sure that they bring to book those involved in the discharge of effluents into rivers. The adoption of Mathematical Model which describes the overall nutrient runoff and the catchment model suitable for describing the overall transport of water and nutrient through the rivers basin should be encouraged as practiced in Poland and other developed countries of the world.
