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...

La réserve de biosphére du Delta du Saloum OceanDocs
Dia, I.M..
La RBDS est un site d’importance biologique national, sous régional et mondial tant pour sa végétation, sa grande et moyenne faune, son avifaune, son ichtyofaune. Cette richesse lui confère une importance économique de premier plan (pêche, tourisme, agriculture, petite industrie, etc.). Dans cet article, il est question de faire une description de cet écosystème et de ses enjeux.

Rapport national sur l'état de l'environnement marin et côtier OceanDocs
Le domaine maritime sénégalais s’étend de 18°00 N, -20°00 W, -16°30 E, 12°15 S ; la presqu’île du Cap-Vert située entre 14°30 N et 15°00 N le divise en deux zones aux caractéristiques topographiques distinctes. Au nord, le plateau continental est peu étendu vers le large et orienté Nord-Nord/Est. Au sud de la presqu’île, le plateau s’élargit et le talus continental est orienté nord-sud. L’embouchure du fleuve Sénégal au Sénégal au Nord de la presqu’île du Cap-Vert et celles de la Gambie et de la Casamance au Sud constituent également un trait marquant de cette région. Les travaux réalisés au Sénégal en océanographie ont montré : - l’existence de deux saisons marines aux caractéristiques très différentes qui se succèdent : une saison chaude de juillet à...

Tamaño, estructura y distribución estacional de poblaciones de aves acuáticas en el fiordo Ultima Esperanza y Canal Señoret, Región de Magallanes OceanDocs
Guineo, Oscar; Garay, Gladys; Mutschke, Erika; Ríos, Carlos.
Between September 2001 and September 2002, Ultima Esperanza fjord and Señoret Channel were surveyed, sailing from Puerto Natales. Information on abundance, structure and distribution of aquatic and land birds observed during the sail is presented. We found 30 species of aquatic birds and 3 land birds.: 1 In Danger, 3 Vulnerables and 1 Insufficiently known. Our analysis shows that these fjords contained one of the biggest winter abundance of birds of the region and is a nesting area for many species. Furthermore, we proposed that the fjord constitute a core area for aquatic birds in summer when fresh water lagoons and ponds get dry. Finally, we make special reference to the need to implement a management plan in the area.

The eastern Africa flamingo Lakes: Building partnerships for sustainable resource management OceanDocs
Raini, Jackson A..
The saline alkaline lakes of the Eastern Africa Rift Valley 'Flamingo Lakes' support diverse biological resources that are of global, regional, national and local importance. These lakes form the center piece of some of the world renowned national parks and conservation areas and are major feeding, staging and displaying ground for the region's Lesser flamingo (Phoeniconaias minor), Greater flamingo (Phoenicopterus ruber) and for over 70 species of water birds. Unsustainable land use practices within the basins of these lakes during the last four decades have adversely affected the environment in many ways. Notable among the effects are the diminishing forested areas, rampant soil erosion, waste disposal problems and deterioration in catchment water...
