This report is part of the Global Environmental Facility (GEF)-Medium Size Project (MSP) on the Development and Protection of the Coastal and Marine Environment in Sub-Sahara Africa. The objective of the first phase of this project , involving eleven Sub-Saharan African countries (Côte d’Ivoire, Gambia, Ghana, Kenya, Mauritius, Mozambique, Nigeria, Senegal, Seychelles, South Africa and Tanzania), are to: • identify sites or living resources of national, regional and global significance that are suffering measurable degradation; • identify sites and resources of regional significance that, although not currently degraded, are threatened with future degradation either because of the sensitivity of the receptor or the magnitude of the activity posing the... |

The countries bordering the Golf of Guinea are the Ivory Coast, Ghana, Togo, Benin, Nigeria, Cameroon, Guinea Equatorial, Gabon and Sao-Tome-et-Principe (which is actually an Island in the Golf of Guinea). These countries together make up about one third of the population of Sub-Saharan-Africa. In the coastal zones the population has considerably increased. Abidjan, the capital of the Ivory Coast, is estimated to have a population of 2.5 million. With a yearly growth rate of 5% it will augment to 8 million in 2025. In Nigeria, Lagos, which is situated in the coastal zone, has more than 9 million inhabitants. In Cameroon, Duala, which is situated in the estuary Wouri, has more than 1.4 million inhabitants. In Ghana, Accra and its metroplitan zone has... |

La Commission Sous Régionale des Pêches (CSRP), qui est un organisme intergouvernemental de coopération halieutique dont l’objectif global est l’harmonisation à long terme, des politiques des pays membres en matière de préservation, de conservation et d'exploitation durable de leurs ressources halieutiques et le renforcement de leur coopération au profit du bien-être de leurs populations respectives, a obtenu par l’intermédiaire de la Banque mondiale, un Don du Fonds pour l’Environnement Mondial (FEM) et du Gouvernement du Japon, pour la préparation d’un Projet Régional des Pêches en Afrique de l’Ouest (PRAO) pour trouver une solution à la problématique susvisée. Ce projet implique 9 pays côtiers: la Mauritanie, le Cap Vert, le Sénégal, la Gambie, la... |

In this work the result of the project “Determination of the environmental impact on aquaculture in the coastal zone" is presented. Where there were sampled more than 28 points. The water quality of the ecosystems is studied around the shrimp farms like coastal lagoons, rivers and the coastal area, where the shrimp farm get the water from, and at the same time the waste water of the process is spilled. The obtained values of the analisis in water and silts give a valuation of the environmental state of the area; revealing that the lagoon Las Playas is in a not well environmental state, (salinity of 47 ppt, DQO between 3,26 and 6,14 mg/L, N-NO3 700 - 900 µg/L, ammonium 36 - 148 µg/L and silicates between the 1600 and 3400 µg/L) and silts (carbon and... |

The concentration of hydrocarbons of petroleum in marine sediments in areas of industrial, harbour and fishing interest to the N of the island of Cuba, as the bays of Cienfuegos, Port Father, Guantánamo, Matanzas with special emphasis in Sagua La Grande and Havana. The results showed high levels of contamination for these organic compounds in the bay of Havana, with a medium 1 220 mg·kg-1 dry matter. The biggest accumulations were in the creeks of Marimelena and Atarés. A tendency exists to diminish the degree of contamination for petroleum in these sediments. In the bay of Sagua La Grande the concentrations of total hydrocarbons were not high (averague 45 mg·kg-1 dry matter), and it allowed to classify to this ecosystem with very little influenced by... |

The West African coastal zone is rich in estuaries and lagoons. Estuaries are abundant in the area from the mouth of Senegal to Guinea (e.g., Sine Saloum, Casamance); lagoons are generally present from Cote d'Ivoire to the Niger Delta in Nigeria (e.g., Ebrie Lagoon, Porto Novo Lagoon, Lagos Lagoon). Because of their important diversity, it is difficult to give their physical and biological definitions. They are all, however, characterized by a typical and rich fish species composition |

Les analyses granulométriques des sédiments superficiels de la zone côtière située entre Ras Taguermess et Ras Marmours montrent que les petits fonds (-2 à -10 m) sont couverts par des sables fins aux sables grossiers (la moyenne est entre 0,39 et 3,34 ), généralement mal à très mal classés. Cependant, le haut de plage situé entre Ras Taguermess et Ras Marmour est couvert essentiellement par des sables fins et des sables moyens (la moyenne est entre 1,082 et 2,823 ). La répartition spatiale des sables ne montre pas un grano-classement décroissant ou croissant des sédiments de la côte vers le large. Cette distribution est due à l‘existence d’une énergie importante où la houle joue le rôle essentiel sur leur répartition. L’étude granulométrique montre aussi... |

This report presents the integrated case study for Egypt carried out under an OECD project on Development and Climate Change. The report is structured around a three-tiered framework. First, recent climate trends and climate change scenarios for Egypt are assessed and key sectoral impacts are identified and ranked along multiple indicators to establish priorities for adaptation. Second, donor portfolios are analyzed to examine the proportion of development assistance activities affected by climate risks. A desk analysis of donor strategies and project documents as well as national plans is conducted to assess the degree of attention to climate change concerns in development planning and assistance. Third, an in-depth analysis is conducted for coastal zones... |

En Afrique de l'Ouest et du Centre, plusiers études ont porté sur les variations du niveau marin mettant en évidence d'ianciennes plages avec des ...-rock. L'analyse statistique des données marégraphiques disponibles, quoique relativement lirnitécs, des stations littorales d'Abidjan, de Takoradi et de Téma, de différentes durées, montre, a partir des données de Takoradi, des tendances variables.

Coastal resource utilization and management systems, bothtraditional and more recently conceived, were studied in Mecufidistrict, northern Mozambique in a post-conflict situation prior towhich a significant migration of people to the coast had occurred.A wide variety of coastal biotopes containing a multitude ofresources had been affected in various ways. Intertidalorganisms exhibited signs of decreasing abundance and averagesize, whereas offshore fishes and mangrove forests did not showsigns of overutilization. It was observed that traditional coastalmanagement systems were still influential, but that newerinitiatives were only beginning to enter into significant dialogueand cooperation with these. In the current circumstances ofpeace and political... |

ABSTRACT To counteract the spread of the Covid-19 pandemic disease, the Colombian government decreed a quarantine period from March 24 to July 1, 2020, which forced the cessation of tourist activities and the closure of the main tourist destinations of the Colombian Caribbean: Santa Marta, Cartagena, and San Andrés. During this period, a significant increase in the environmental quality of these coastal zones was perceived. To quantify environmental changes in the coastal zone, the variation in chlorophyll concentration and total suspended solids observed by the Sentinel-3 satellite mission, 30 days before and after the start of the quarantine, was analyzed. The results showed a decrease in the concentration of chlorophyll (> 20 %) and suspended solids... |
