There is a growing appreciation of the natural functions of wetlands, as well as the values and different forms of uses that humans attach to them. In order to sustain their productivity, there is a need for wise-use and special conservation strategies. Wetlands are one of the most fruitful areas of archaeological research, and the ideal setting in which to study the interactions between physical processes and human actions that encapsulate and exemplify many of the themes of human impact on the environment. However, all the beneficial functions of wetlands seem to be in danger of being lost to draining and in-filling. With these factors in mind the main objective of this study was to investigate the interaction of indigenous knowledge and institutions in natural resource management for sustainable food security and rural livelihoods in Simuyu Basin, a sub-catchment of the Lake Victoria basin in Tanzania. The main focus was on wetland resources utilisation and how local people apply the knowledge and skills to actively manage their wetlands for poverty alleviation purposes.

This book constitutes a pioneering and unique work on Lake Victoria. It is the world’s second largest fresh-water lake and supports the livelihood of more than 30 million people. Surprisingly, there has been no comprehensive book addressing its problems and potentials. Ecology, environmental pollution and resource management are some of the issues addressed by this comprehensive insight into the limitations, challenges and opportunities facing Lake Victoria.

This book synthesises the historical trends of the lake fisheries, the lake ecology, biology and biodiversity, socio-economics, stock assessment, aquaculture, fish quality assurance, environmental quality and management of the fisheries resources. The evolution of fisheries in Lake Victoria has undergone dramatic changes over the last few decades, leading to both ecological and socio-economic consequences. The lake has changed from one dominated by haplochromines in the 1950s, to one currently dominated by Nile perch, ‘dagaa’ (Rastrineobola argentea) and Nile tilapia. These changes have mainly been driven by the introduction of the predatory Nile perch in the lake, eutrophication due to increased human activities in the catchment, increased human population growth, overfishing and changes in the global climate system. This work should therefore be a particularly useful reference to fisheries scientists and managers, potential investors, students and other professionals who may be interested in the Lake Victoria fisheries.

A source book for future research and management activities, these 20 papers cover wetland issues in Kenya and underline the need for a national wetland program.
