Degradation of the riparian wetlands in the Lake Victoria basin - Yala swamp case study OceanDocs
Thenya, Thuita; Wassmann, Reiner; Verchot, Louis; Mungai, David.
Land degradation is as a result of broad range of scales and factors, which include biophysical, climatic, demographic and socio-economic. The aim of this paper was to provide an analysis of wetland utilisation, ecosystem degradation and their effect on the Lake Victoria (Kenya) ecosystem. This involved analysis of socioeconomic and remote sensed data. The main sources of wetland degradation in the Lake Victoria basin were identified as (1) farming activities, (2) grazing and macrophyte harvesting and (3) coupled with catchment degradation-deforestation. These factors were closely related to the demographic dynamics and unsustainable land utilisation practices. Socio-economic data provided valuable insight on the pattern of wetland utilisation and possible...

Distribution of economic benefits from the fisheries of Lake Victoria OceanDocs
Abila, R.O.; Odongkara, K.O.; Onyango, P.O..
The Lake Victoria fishery contributes immensely to the socio-economic development of the riparian states. The East African Community has designated the lake basin as an ‘economic growth zone’, with the potential to develop into a major economic region. The fisheries are vital in creating employment opportunities, mostly rural-based, thereby helping to reduce rural-urban migration. Fish is also a rich source of animal protein for human consumption and provides raw material (fishmeal) for processing animal feeds. The fish industry contributes to GDP and has continued to be an important source of foreign exchange earned from fish exports. Besides, the fish industry contributes to the national and local government revenues through levying of various taxes,...

Lakes water quality monitoring and management programme in developing countries OceanDocs
Mutia, Silas M.
Developing Countries face an array of traditional and modern lakes water quality problems ranging from faecal contamination to toxic chemicals. Moreover, they do so in an economic environment that is severely restricted, an institutional environment which is often poorly structured, and for which the modern scientific knowledge base is frequently poorly understood and applied. Agencies in many developing countries recognize this as major impediment to sustainable development, especially as water quality has become one of the leading economic issues for the purposes of development and investment. Generally water quality programmes tend to suffer from traditional approaches, both of methodology and legal/administrative. The Consequence is that many...

Socio-economic dimensions of conservation of wetlands in African dry lands: A case study of River Ewaso Ngiro basin in southern Kenya OceanDocs
Gichuki, Nathan N.; Macharia, Jane M..
Wetlands that occur in arid and semi-arid areas have unique characteristics and support unique biodiversity. The permanent wetlands are relatively small and isolated by large areas of dry land. There are however, numerous temporary or seasonal wetlands that contain water for only short period in the year. These wetlands contain water, a critical resource for all people, livestock, wildlife and plant life. The availability of fresh water minerals, pasture and other useful products attract humans, thereby making the wetlands to become focal points of economic development and indeed urbanization. The changing lifestyles of resident communities, such as increased focus on subsistence and commercial agriculture and sedentarization as opposed to nomadic...
