Última Preliminary assessment of the cocial, economic and environmental impacts of Water Hyacinth in Lake Victoria basin and status of control OceanDocs Mailu, A.M.. The paper presents preliminary data collected in an assessment of the social, economic and environmental impacts of water hyacinth in the Lake Victoria Basin. A summary of the status of control and strategies for the future is given. The report draws on field observations made, studies through interviews of affected communities and organisations, personal communications and published reports by scientists in the region. Lake Victoria, the world’s second largest freshwater body, supports an estimated 25 million people living in the Basin, with an estimated gross economic product of US$3–4 billion annually, mainly from subsistence agriculture and fishing in Kenya, Uganda, Tanzania, and parts of Rwanda and Burundi. The multiple activities in the Lake Victoria...

The impact of agro-industrial activities on the water quality within River Nyando, Lake Victoria Basin (Kenya) was studied at different hierarchical levels between August 1997 and June 1999. Triplicate water samples were collected on a monthly basis from various stations ranging from the source to the mouth of the river and analyzed for selected physical and chemical water quality parameters using standard analytical methods. Statistical analysis was performed using MINITAB and STATISTICA computer packages. Agricultural land use was found to be the major factor contributing to changes in water quality. Salinity and pH varied at river basin scale, turbidity, TDS and conductivity at catchment scale, while DO, alkalinity and pH at subcatchment and river reach...

Ano: 2006 URL: http://hdl.handle.net/1834/3501 Effects of land use changes on bird composition along River Njoro: A watershed of Lake Nakuru OceanDocs Shivoga, W.A.; Ngugi, F.M.; Muchiri, M.S.; Miller, S.N.. The rift valley lakes and their associated watersheds are home for millions of resident and migratory waterfowl. However, they have been recently challenged by land use changes. Lake Nakuru (Kenya) supports diverse biological resources of global, regional and national importance. It is saline and River Njoro is its main source of freshwater. Deforestation, cultivation and urbanization in vital watershed areas have altered the hydrological regime of River Njoro. There is need to preserve and restore aquatic, riparian and terrestrial biological diversity in the watershed to be able to restore and maintain ecological health of Lake Nakuru. The impact of these recent land use changes on birds in the River Njoro Watershed is of concern to conservationists. This...

Ano: 2006 URL: http://hdl.handle.net/1834/1499 The role of the Yala swamp lakes in conservation of Lake Victoria region haplochromine cichlids: evidence from molecular genetic and trophic ecology studies OceanDocs Abila, R.; Salzburger, W.; Ndonga, M.F.; Owiti, D.O.; Barluenga, M.. Lake Kanyaboli (Kenya), a satellite lake of Lake Victoria, has been suggested as a potential refugium for haplochromine cichlids that have gone extinct in Lake Victoria. We employed mitochondrial DNA and microsatellite DNA molecular markers as well as feeding ecology studies to re- evaluate the evolutionary and ecological significance of Lake Kanyaboli haplochromines. The mitochondrial DNA and microsatellite markers revealed high genetic diversity in the endangered Xystichromis phytophagus and also the presence of mtDNA haplotypes that may have either gone extinct in Lake Victoria or have arisen in situ. Lake Kanyaboli thus acts as a ‘genetic reservoir’ for the Lake Victoria species flock. Gut content analysis revealed six trophic groups among the six...
