| Nigeria, one of the world’s largest oil exporters, has a coastline of approximately 853km facing the Atlantic Ocean. This coastline lies between latitude 4o 10’ to 6o 20’ N and longitude 2o 45’ to 8o 35’ E. The Nigerian coast is composed of four distinct geomorphology units namely the Barrier-Lagoon Complex; the Mud Coast; the Arcuate Niger Delta and the Strand Coast. 90-95% of export revenues in Nigeria is from the oil sector. Nigeria’s oil reserves are about 31.5 billion barrels, while Nigeria’s crude oil production averaged 2.118 million barrels per day in 2002. Oil spillage is a major environmental problem in Nigeria. Between 1976 and 1996 Nigeria recorded a total of 4835 oil spill incidents, which resulted in a loss of 1,896,960 barrels of oil to the... |

| The 11,300 km of coastline of the 11 participating sub-Saharan African countries are characterized by a diversity of ecosystems and an abundance of natural resources. The national reports describe ecosystems which include mangrove swamps, estuaries, rocky shores, coastal wetlands and coral reefs. These coastal and marine habitats and resources fulfil a number of functions: they moderate storm impacts and protect coastal features, recycle nutrients, absorb and break down wastes, provide human and wildlife habitat, provide sources of livelihood for millions of coastal dwellers, maintain biodiversity, and present opportunities for recreation, tourism, transport, trade, and employment. Commercial fisheries contribute significantly to the national GDP, export... |

| L’eau est l’un des éléments de base de tous les écosystèmes. En fonction du milieu où elles s’écoulent, les ressources hydriques sont plus ou moins importantes, accessibles ou vulnérables. Les caractéristiques de l’eau sont dépendantes du milieu biophysique environnant, mais elles peuvent être fortement modifiées par la présence humaine. En effet, l’eau est une composante fondamentale des activités humaines, que ce soit pour l’alimentation, la production de biens, le commerce ou les loisirs. Ces activités exercent une pression sur les écosystèmes naturels. Elles modifient la ressource hydrique sur le plan quantitatif et qualitatif, entraînant des répercussions plus ou moins importantes sur les écosystèmes touchés et, par conséquent, sur les espèces... |

| Sediment characteristics and tidal currents were studied in the 1500 ha intertidal area south of Inhaca Island, Mozambique. Thetide is semi-diurnal with a range at spring of about 3 m. The area connects directly to the ocean through the Ponta Torres Straitand (indirectly) through several narrow tidal channels ending up in Maputo Bay. Velocities of up to 0.75 m s-1 were measured in the Ponta Tones strait. After Low Water, Indian ocean water starts entering the tidal flats, while entrance from the MaputoBay side is delayed by one to several hours. With only one tide gauge and one current meter at hand, we found indications of ahigher mean sea level on the oceanic side (probably due to ocean wave set up) and a mean flow in the Ponta Torres Straitdirected... |

| The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango... |

| The Benguela Current Large Marine Ecosystem (BCLME) flanks the coastal areas of Angola, Namibia and South Africa, representing a unique upwelling ecosystem. Striving to establish effective management of the BCLME, the BCLME Programme is a multi-sectoral initiative funded by the Global Environment Facility (GEF) and further financial and in-kind contributions from the three member countries. The United Nations Development Programme (UNDP) implements the Programme and the United Nations Office for Project Services (UNOPS) is the executing agency. Communities in the coastal areas of Angola, Namibia and South Africa depend on the coastal and inshore resource for their survival and livelihood and therefore have a large stake in the management of this Large... |

| The Benguela Current ecosystem is situated along the coast of south western Africa, stretching from east of the Cape of Good Hope, in the south, northwards into Angola waters and encompassing the full extent of Namibia’s marine environment. It is one of the four major coastal upwelling ecosystems of the world which lie at the eastern boundaries of the oceans. Like the Humboldt, California and Canary systems, the Benguela is an important centre of marine biodiversity and marine food production. Its distinctive bathymetry, hydrography, chemistry and trophodynamics combine to make it one of the most productive ocean areas in the world, with a mean annual primary productivity of 1.25 kilograms of carbon per square metre per year—about six times higher than the... |
