Lake Victoria, as the second largest freshwater lake in the world, and with the world's largest freshwater fishery, has undergone large changes over recent decades. Human activities together with meteorological variability and climate change, have led to a series of hydrological variation. Under the anthropogenic effects like overfishing, ecosystem loss, pollution and eutrophication, fish stocks are depleted and the sustainability of the lake is degraded. In order to avoid serious impacts on people, animals and plants that depend on the lake ecosystem, sustainable management of water resources and aquaculture activities in the region is necessary. My research aim to understand long-term environmental impacts of aquaculture to inform sustainability in Lake Victoria, Kenya. This research will build on previous palaeo-limnological work of the main lake, but particular focus will also be placed on the Winam Gulf where the effects of intense aquaculture are seen. Currently I concentrate on a centre core and its changes of historical diatom.
I used to work on the Holocene climate change by Diatom from Lake Kanas, a glacial influenced lake in northwest China.
