AbstractWater is potential to the lives of the people and biodiversity. The objective of this study was to examine households’ awareness on the contribution of their human activities in lowering the quality of water resources around Lake Victoria in Misungwi District, Tanzania. The expansion of human activities due to population increase possibly led to wetlands encroachment around the lake leading to contamination of water resources of Lake Victoria Basin. This study used qualitative approach to assess the impact of human activities on water resources using questionnaires to collect data from a random sample of 219 heads of households. Participant observation, FGDs and informants guided by checklists were employed in order to triangulate information obtained. The results showed that, human activities pressure exerted by population exodus from drought hit areas to wetlands around Lake Victoria in one way or the other affected the quality of water of the latter in the environment. Also, there was a direct relationship between education level, human activities and awareness status of respondents and water resources polluting effects and the general environmental degradation of Lake Victoria in the study area. The study concluded that; there was a great correlation between increased human activities propelled by population increase and low water quality in the environment around Lake Victoria. It recommended that; collective efforts guided by relevant policies should focus on building awareness on sustainable use of the Lake Victoria water resource for improvement of the local environment and community.
