The life history and survival of Neochetina in Lake Victoria basin: Basis for biological weed control OceanDocs
Ochiel, G.R.S.; Njoka, S.W.; Manyala, J.O.; Okeyo Owuor, J.B..
Using our own experimental data and published data, we review information on the control process of water hyacinth and its status in Lake Victoria basin, Kenya. Experimental results show that the mean fecundity of the two weevils is 290 and 237 eggs per female laid over a period of 16 weeks, with an adult longevity of 98 and 112 days for Neochetina bruchi and N. eichhorniae respectively. There was significant difference between the egg laying capacities of the two weevil species (p=0.002). The survival rate of the two species was significantly different (p<0.05) for all life stages except for larvae to pupa. There was no significant interaction between the species and the method of experimental egg setting (p<0.05). The fecundity of both N. bruchi...

Environmentally Sound Technologies for Decision Making in Integrated Coastal Management: Prospects of Co-Operation with UNEP-IETC for Education and Training in the Mediterranean OceanDocs
Casanova, L.G.C..
The present crisis in urban management in developing and 'transitioning' countries is largely the result of rapid urbanization and modernization which came to these countries without the basics of planning and management that should have gone hand in hand with them. Because economic growth was the primary goal, the advent of urban development further resulted in the degradation of the urban environment, notably its freshwater and marine resources. Today, the need for urban environmental management has become urgent more than ever especially for decision makers. Urban environmental management is a high level skill that is expected from decision makers - those who have the responsibility to establish priorities and create a balance between urban development...

Caso de Estudio No. 2: Estado de la pesquería de la langosta espinosa (Panulirus argus) y su relación con factores ambientales y antrópicos en Cuba OceanDocs
Puga, R.; Piñeiro, R.; Capetillo, N.; de León, M.E.; Cobas, S..
Las capturas de langosta espinosa Panulirus argus (Latreille, 1804) en Cuba alcanzaron sus mayores volúmenes en la década de 1980 con un promedio anual de 11565 ton. En la década de 1990, la captura descendió a un promedio de 9327 ton, lo cual se ha visto agudizado entre 2000 y 2007 con un promedio de 6262 ton y una mayor variabilidad de las capturas, a pesar de un perfeccionamiento del sistema de manejo pesquero dado por: la disminución del esfuerzo pesquero y de la tasa de mortalidad por pesca desde 1999, el aumento del período de veda desde 2001 y el incremento gradual de la talla mínima legal de captura a partir de 2004. Los análisis más recientes sobre el estado de esta pesquería fueron presentados en el Quinto Taller Regional sobre la...

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...

Piñeiro, R.; Puga, R.; González-Sansón, G..
Social-economical activities in the western area of the Batabanó gulf, southern coast of Pinar del Río are analized. The communities do not have a compression of the environmental on the resource, as well as the fragility of the coastal ecosystems. Between the negative effects over the environmental are the indiscriminate cutting, the pollution, all of them due to the ignorance of the mangove forests benefits. The economic activities are industrialists and agriculturists where the spiny lobster fishery (P. argus) is the most important. A decrease of the level of captures from 1990 to 2003, was observed. This behavior reflects the deteriorate conditions of the environment, which limit the recruitment and affect some nursery areas, as well as the...

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...

The coastal zone and oceanic problems of Sub-Saharan Africa OceanDocs
Ibe, A.C..
The coastal zone and oceans surrounding Sub-Saharan Africa, with their vast resources of food, energy, and minerals, not only are composed of various fragile ecosystems, but are scenes of a variety of often conflicting uses. At present, the uncontrolled development of the coastal zone and ocean and the almost haphazard exploitation of their natural resources threaten to turn the promise of economic prosperity into an environmental nightmare that portends great dangers for present and future generations. There is the urgent need to put in place national management policies that address the environmental controls and procedures to be applied in pursuit of economic development. However, the oceans have no physical boundaries corresponding to national...

The role of wetlands in lake ecological functions and sustainable livelihoods in lake environment: A case study on cross border Lake Jipe - Kenya/Tanzania OceanDocs
Ndetei, Robert.
Wetlands are highly productive ecosystems. Their values and functions support other ecosystems and are significant to economic development. They once covered large areas of the world and are now among the rarest and most at-risk ecosystems. They are highly valued for their recreational, educational, scientific, aesthetic, spiritual and cultural values; and form an important component of lakes that provide critical functions influencing lake ecological functions. Despite the important roles in sustaining vibrant lake ecology, supporting economic development and elevating poverty, almost all wetlands in the world are threatened by diverse human induced factors. Lake Jipe striding across the Kenya-Tanzania international boundary is an important ecosystem to...
