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... |

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 second volume of a guide to integrated coastal zone management opens a new dimension by discussing the processes involved in a more complete and dynamic way than the first, To fulfil1 this requirement, an expanded work group, drawing upon the knowledge of experts in political science, economics, and sociology, devoted over two years of effort (1999 - 2001) to its completion, following a disciplined working method. A dual principle prevailed in the application of this method. On one hand, it prescribed an approach structured as a series of steps, and on the other, it demanded that real situations be brought to light, emphasizing case studies of experience with or analysis of coastal management. |

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... |

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. |

Cette étude traite des relations floristiques et dynamiques entre îlots forestiers et végétations périphérique dans la plaine côtière du sud du Togo. Les îlots forestiers sont essentiellement des fôrets sacrées et des forêts "pare-feu" à proximité des villages. Des relations évidentes ont été établies entre les îlots forestiers et les végétations périphériques : 1) phytogéographique, 51,8 % des espéces des îlots et 32,4 % des espèces des végétations périphérique sont d'origine forestière; 2) floristique, 870 espèces ont été recensées dont 649 dans les îlots et 610 dans leurs environs. 373 espèces leur sont communes.... |

El sector pesquero de la I y II Regiones, comprende un importante segmento de la economía nacional, contribuyendo fuertemente con el empleo en las zonas costeras y al abastecimiento de materia prima. En esta macrozona la pesca está representada por dos sectores: industrial y artesanal y a su vez está constituída por tres segmentos principales de recursos: pesquerías bentónicas, pesquerías de peces y recolección de algas. Dada la importancia de la actividad extractiva artesanal e industrial en la franja de las 5 millas de la I y II Regiones, en el presente informe se describe y analiza la actividad extractiva de las principales pesquerías. Además se entrega una completa revisión de los principales antecedentes eco-pesqueros del litoral de las regiones I y... |

In this article we described the concept of “regional sediment management” (RSM), and identified opportunities for and impediments to implementing regional approaches to sediment management, and also summarized the background information and applications of RSM. Furthermore, we considered the needs of RSM studies and, suggested the framework for developing RSM strategies, and described the specific studies for the Xiamen region. |

An assessment of the environmental quality in western Gulf of Batabanó, southern coast of Pinar del Río province, Cuba and its relationship with the reduction of freshwater supply by rivers is presented. Main characteristics of natural factors are analyzed, such as river supply to the coast, water temperature, salinity, dissolved oxygen, turbidity, pH, nutrients and organic nitrogen coal in sediments. Besides, submarine vegetation and general conditions are also analyzed. River supply of water was estimated in 1860412,24 m3/day, value which is only 20 % of what it used to be, therefore salinity has increased (> 35 ‰).and dissolved oxygen concentrations are lower (2.8-5.5 mg/l). Ammonia concentration are very high (> 50.0 μg/l) as well as higher... |

The African Process for the Development and Protection of the Coastal and Marine Environment, particularly in Sub-Saharan Africa, has progressed from mere words and resolutions to concrete action. Through this regional initiative, A f r i c a n countries developed key strategies to address the global oceans and coasts challenges within the overall context of sustainable development. As we prepare for the World Summit on Sustainable Development (WSSD), the biggest event ever to be hosted on African soil, the onus is ever more pressing upon us to realise our responsibilities and to ensure that we actively bring about sustainable development in Africa. We must not lose sight of the overall objectives of the African Process – to eradicate poverty and to ensure... |

The spatial and temporal changes of the fish assemblage areas composition at the coastal ecosystem of the western South Atlantic (34 degree -41 degree S) during six springs (1981, 1983, 1994, 1995, 1998 and 1999), were examined. For each assemblage area the most common species and those species that discriminate it from adjacent assemblages areas within years, were identified. Within each area, also resident (common in all years) and facultative (contributing to less than 90% of similarity within any year) species, were studied. Also were identified what parameters control the main structuring of the fish community on the spatial and temporal patterns. In order to determine how the environmental factors influenced the fish community structure, the... |
