| The work presented in this PhD thesis has not been carried out within a single, well-defined project. Instead, it integrates the results of a number of studies conducted from 1994 onwards, each of which had different clients and objectives. The common theme of the studies has been the description and analysis of elements that determine how coastal systems and communities would and could respond to climate change and, in particular, how this response may be assessed as part of coastal vulnerability studies. Coastal zones are amongst the most dynamic natural environments on earth, providing a range of goods and services that are essential to human social and economic well-being. Coastal zones represent the narrow transitional zone between the world’s land... |

| Like all coastal zones, the cameroonian coast is a complex and diversified environment, controlled by atmospherice, marine and terrestrial phenomena. This diversity is a result of natural changes, human activities, and even the diversity of resources. Coastal zone falls among the most productive ecosystems in the biosphere; they possess specific attributes from which socio-economic development can either benefit, or suffer. Thus their harmfulness is a commensurate with their potentials. In effect, these zones are often subjected to chaotic, and even destructive exploitation wich tends generally to off set the ecological equilibria. |

| 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... |

| 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... |

| La côte togolaise, basse et sableuse, soumise è une violente érosion par suite d'une série d'erreurs d'aménagements, a fait l'objet en 1987-1988 d'importants travaux destin's à protéger sur 15 km la ville d'Aného et l'usine de phosphates de Kpémé, principale industrie du pays. La préparation de ces travaux, de protection, rendus indispensables par la gravité des enjeux économiques et sociaux, a nécessité des études hydrologiques et sédimentologiques très détaillées, ainsi que la construction et l'exploitation par un bureau d'étude spécialisé de deux importants modèles physique (32 x 20 m) destinés à optimiser le dispositif de protection et à déterminer l'évolution du trait de côte sur une période de 25 ans... |

| 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... |

| Marine fisheries in Kenya are based on a small number of species, the most important of which are demersal and caught by artisanal fishermen operating between the shoreline and the reef. Of the national total annual fishery production only 7.4% comes from marine waters. Freshwater fish landings in Kenya have always been higher than those from coastal waters. However, while the disparity was not too great until the mid-1970s, the difference has broadened significantly due to the marked increase in freshwater fish production since then. While freshwater fish production increased from around 22,000 tonnes in 1975 to 138,000 tonnes by 1989, marine fish landings have remained consistent between 5,000 and 8,000 tonnes over the same period. |

| The eastern African coastal forest ecoregion is recognised as one of Africa’s centres of species endemism, and is distributed over six countries (Somalia, Kenya, Tanzania, Mozambique, Zimbabwe and Malawi). Most is found in Kenya, Tanzania and Mozambique, which form our focal region. The coastal forests are fragmented, small and surrounded by poor communities that have a high demand for land and forest resources. Although coastal forests have significant cultural and traditional values for local communities, they do not receive adequate support from the relevant government authorities and international conservation institutions. WWF has over 10 years research and conservation experience on the eastern Africa coastal forests in Kenya, Tanzania and Mozambique... |
