González, J.; Tapia, C.; Wilson, A.; Stotz, W.; Orensanz, J.M.; Parma, A.M.; Valero, J.; Catrilao, M.; Garrido, J..
En la III y IV Regiones las áreas de manejo y explotación de recursos bentónicos (AMERB) se han establecido como la principal herramienta de manejo del recurso loco (Concholepas concholepas). Sin embargo, su aplicabilidad para la administración y aporte en términos del desarrollo sustentable, aunque sugerentes, requieren de una evaluación objetiva, en cuanto al manejo de carácter discreto que se ha establecido para cada AMERB, desconociendo la eventual interacción espacial de las mismas. En este marco, se desarrolla una aproximación para evaluar el desempeño de las AMERBs desde una perspectiva integral bajo un enfoque metapoblacional. Si bien el estudio está orientado a proporcionar la información de campo que permita probar la hipótesis de metapoblaciones...

Implications of climate change on the management of Rift Valley lakes in Kenya. The case of lake Baringo OceanDocs
Ngaira, Josephine K..
Climate patterns of the World became very variable during the last half of the twentieth century. Causes of this variability/change have been identified as: Sun Spot activity, ozone depletion, decline in the solar beam, with the more pronounced especially in Africa being Increased atmospheric carbondioxide, and albedo change due to anthropogenic factors. The most affected weather elements by the above mentioned factors particularly in the tropics are Rainfall and Temperature, and the climatic environments most affected by the named weather elements are the arid and semi-arid lands which are already moisture constrained. The rift valley in Kenya, where most of the lakes are located experience Arid and Semi-Arid climate. The lakes located in this region are...

Marine botanical resources of Kenya coast OceanDocs
Ruwa, R.K..
Investigations have shown that Kenya coast botanical resources are underutilized and have not been realized as exploitable resources. Apart from the mangroves which are heavily exploited, algae and marine angiosperm resources are the least exploited. In a step to realize these as future exploitable resources their current uses in Kenya and how they could be used is discussed. A review of research work which could be seen as a prelude to further research is also included.

Impact of agro-industrial activities on the water quality of River Nyando, Lake Victoria Basin, Kenya OceanDocs
Raburu, P. O.; Okeyo-Owuor, J.B..
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...

What is the socio-economic value of the wetlands fisheries? The case of Yala Wetland in Kenya OceanDocs
Abila, R.O.; Othina, A..
Wetlands in most parts of the world are under threat of over-exploitation partly because their socio-economic value is not well known. Yala Wetland, the largest freshwater wetland in Kenya, with a large part of it bordering Lake Victoria’s shoreline, faces even greater threats of extinction. This wetland measures about 17,500 ha and is host to a number of indigenous fish species, animals and plants which are exploited by the local communities for subsistence and commercial purposes.There has been pressure to reclaim portions of this wetland for agricultural activity. So far, 2,300 ha has, indeed, been drained for commercial agriculture. Furthermore, it is difficult to control effort in the exploitation of the remaining wetland resources since the...

The potential role of constructed wetlands in protection and sustainable management of lake catchments in Kenya OceanDocs
Oketch, M. A..
Constructed wetlands are man-made ecosystems, which are specially designed for treatment of wastewater and non-point source pollution. Constructed wetland technology is gaining popularity due to its economically and environmentally sound attributes as a wastewater management option. Freshwater lakes in Kenya are under threat from degradation as human populations in the catchment areas increase, demands for natural resource extraction grow and urbanization and industrialization intensify. Consequently, there is increased surface runoff, causing sedimentation and eutrophication and ultimately deterioration of water quality, habitats and biodiversity. This trend requires integrated and sustainable water resource management strategies. Strategies for...

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...
