    (Kampala International University, School of Engineering and Applied Sciences, 2012-07) Bahati, Moses
    The purpose of the study was to establish the impact of human activities on the wetland eco system in Nakigalala Zone Kajjansi, wakiso district Uganda. The major concern was the factors, activities and effects of human activities on wetlands. The study was conducted among surrounding outgrowers, labour workers, brick laying companies, among others The literature review covered relevant literature from other previous writers, journals, documentary reviews of the impact of human activity on wetland eco-system were reflected in the Literature review.The study used a descriptive study design in which both qualitative and quantitative methods were adopted. In a cross-sectional survey, a total of 40 farmers were inter viewed using several data collection methods including interviews, informal discussions based on questionnaires and observation .The researcher was focused majorly on the activities involved in human activities for example agriculture and their effects on the wetland ecosystem and this was majorly on observation of these effects and practices.Data was analyzed, coded and presented using pie charts. Factors like continuous cultivation of the wetland leads to depletion of soil nutrients, lack of awareness about wetland conservation, political factors of the rich being given free access to wetland natural resources without follow ups and economic factors were all leading to wetland eco-system. After the study, the researcher found out that the use of chemical to kill weeds was a common practice that changes the wetland ecosystem composition through contaminating it and making it inhabitable to the different kinds of biodiversity; use of fertilizers that degrade the soil that without using them in a particular season would mean very poor yields, other pests and disease control using chemical for example kills birds and fish in the water; mechanized harvesting leads to compaction of the soil particles reducing soil aeration.
