Degradation of Wetland Ecosystems: A Case Study of Kisii District, Western Kenya

Abstract Wetlands are essential life support systems and play a vital role in controlling water cycles. Although Kenya has a great variety of wetlands, they are not distributed evenly over the country. Most of the wetlands occur within the well-watered parts of the country such as the coast, highlands and the Lake Victoria basin. Many of Kenya's wetlands are highly vulnerable to changes brought about by human activities. Despite the great ecological and social importance of wetlands in Kisii District and Lake Victoria region in western Kenya, the rising population, together with the need for increased agricultural production, has led to substantial pressure upon the wetlands of this area. This study is a survey of the human impact on these wetland ecosystems to be used as a base in developing sound management policies to allow sustainable utilization of the wetland resources in the district.
