| Mida Creek (Kenya) comprises mangrove forests and other marine resources that are of economic, ecological and environmental importance to the local village communities. In total 116 households (100 of which could be used for numerical analysis), which are estimated to correspond to a coverage of ca. 30 % of the total Mida Creek population, were interviewed to assess the human reliance on mangrove resources in Mida Creek. The survey indicates that mangroves are a major resource of wood for house construction, fuelwood, charcoal and boat building. Minor uses of mangrove products include pharmaceutical and medicinal applications, tanning material and furniture making. Rhizophora mucronata, Ceriops tagal and Bruguiera gymnorrhiza are the major resources... |

| The Kenya coastline extends from 40 4's to 4041's from Kiunga in the North coast to Vanga in the South, wich is a distance of ca 575km. The coastal areas of Kenya are known to be rich and extremely valuable as they concentrate a rich diversity of natural habitats and a large variety of natural resources. Coastal communities have from time immemorial depended on the exploitation of these resources for commerce and industry. Alongs this coastline, mangroves are common feature in delta, creeks, protected bays, island and river estuaries. |

| The coastal area of Tanzania (Fig. 1) encompasses a number of habitats that include coral reefs, mangroves, seagrass beds, sand banks, wetlands and beaches, among others. In addition to being essential linkages in the overall functioning of the coastal area, these coastal habitats support various resources both living and non-living. In addition, for generations the coastal area has provided life support to coastal communities where such activities as fisheries and related activities have played an important role in the social and economic development of local communities. In recent years, coastal tourism and mariculture have immerged as being potentially among most important economic activities nationally. The well being of these habitats and resources... |

| Gazi Bay (4.92°S, 39.50°E; Figure 1) is a shallow tropical coastal water system located on the southern coast of Kenya, approximately 50 km south of Mombasa. The total surface area of the bay including that covered by the mangrove forest is 15 km2. The mangrove forest covers a surface area of about 7 km2 (Kitheka 1996, 1997). Seagrass meadows and mangrove forest cover a surface area of about 12 km2. The bay is open to the Indian Ocean through a relatively wide (3,500 m) entrance, and is mostly shallow with mean depth at the entrance about 5 m. There are several narrow shallow cuts through the reef, which is mostly submerged except during spring tide. The bay is drained by two main rivers, the Kidogoweni River on the north-west part of the bay and the... |

| Les régions côtières de basse altitude sont fortement affectées par le changement climatique. Les mangroves jouent un rôle essentiel dans la protection des côtes : diminution de l’érosion, bouclier naturel contre les tempêtes. Peu d’initiatives abordent le développement de méthodes généralisables à un type d’écosystème ou même à plusieurs sites abritant des habitats similaires. L’examen de systèmes similaires peut conduire à une méthode généralisable dont la mise en oeuvre est susceptible d’orienter le développement de stratégies et de plans régionaux plus appropriés pour faire face aux impacts du CC, compte tenu de leur envergure. |

| A preliminary study of the mangrove fishes was undertaken from March 2000 to September 2001 in the Benin estuarine lagoon system in connected to the Mono river; a dam was constructed on this river to provide the Togo and Benin countries with electricity. The research aims to investigate fish species diversity and ecosystem degradation impacts in order to protect and to improve the mangrove fish resources. Specific objectives were (1) to investigate fish assemblages and distribution in the mangrove/estuarine habitat; (2) to investigate relationships between environment features and biological attributes; (3) to evaluate the estuarine ecosystem degradation, with regard to mangrove destruction and recent evolution of the Mono river caused by a dam... |

| This note reports the faunal species associated with mangroves and other wetlands in nocturnal periods in the Vía Parque Isla de Salamanca in order to support management and conservation planning for this natural park. The study was carried out from September through December 2006 using nocturnal surveys. We report 19 species including invertebrates such as arachnids, crustaceans, and mollusks, and vertebrates such as amphibians, reptiles, birds, and mammals. We focused on those species that are classified as threatened either nationally or internationally, and those for which VIPIS represents an information need and an important area for ensuring their persistence. |

| Mangrove ecosystems on the coast of Cameroon are valuable both for their contributions to local livelihoods and the globally important biodiversity that they contain. However, these areas are threatened by a number of development pressures as well as unsustainable management and harvesting practices of the local communities living there. This project aims to strengthen protection and reduce degradation in these areas by supporting inter-sectoral co-ordination and collaboration (within an agreed national framework) and by helping local communities to redirect local economic activities towards activities that both improve their livelihoods as well as assist with the conservation of globally important biodiversity found in these areas. At the national level,... |

| Mangrove forests are unique ecosystems which provide a range of important goods and services. However, they are suffering high rates of destruction around the world, and will be one of the first ecosystems affected by the predicted sea level rise. This project aims to establish re-planted experimental plots of mangroves in cleared areas. Experimental treatments will consist of plots of three different tree species, along with all possible multi-species mixtures and unplanted controls. Volunteers will assist in planting mangroves, and in measuring a range of biological and physical parameters relevant to important ecosystem functions, such as productivity and growth rates, susceptibility to disease, faunal abundance (of fish and crabs) and sedimentary... |

| Mangroves are forests of salt-tolerant trees and shrubs that grow in the shallow tidal waters of estuaries and coastal areas in tropical regions. They require slow currents, no frost and plenty of fine sediment in which to set their roots. Their muddy waters, rich in nutrients from decaying leaves and wood, are home to sponges, worms, crustaceans, molluscs and algae, and provide shelter for marine mammals, snakes and crocodiles. They act as fish nurseries and help feed life further out to sea. QueenslandÕs mangroves, for instance, do much to sustain the Great Barrier Reef, the worldÕs largest coral reef system. Mangroves are also strongly correlated with the presence of shoals of shrimp further offshore. Mangroves extend over 18 million hectares worldwide,... |

| The purpose of this project is to estimate the ‘total economic value’ of a mangrove ecosystem in part of the Gulf of Fonseca, El Salvador, and to develop a costbenefit framework to compare the sustainable management of the forest with alternative use scenarios. The current management strategy is compared to its sustainable counterpart, and to the partial conversion of the mangrove ecosystem to semi-intensive aquaculture and salt ponds. A variety of different valuation techniques are used to assess the contribution of different products and services of the mangrove ecosystem. Among these techniques, a ‘pseudo production function approach’ is used to calculate doseresponse estimates of the impact of mangrove loss on the productivity of marine and estuarine... |

| En abril de 2007 se estimó la cobertura y se determinaron los atributos estructurales de los bosques de mangle establecidos en la Baja Guajira. La cobertura del bosque se estimó a partir de imágenes ASTER y de un mosaico de fotografías aéreas. La estructura se determinó sobre transectos de 10 m de ancho y del largo de la franja del bosque de mangle. En cada uno de éstos se identificaron y contaron los árboles de mangle, midiéndoles altura total y diámetro a la altura del pecho (DAP) y se calculó el área basal, la densidad y el Índice de Valor de Importancia (IVI). En la Baja Guajira se estimó una cobertura de mangle de 59.9 ha. Laguncularia racemosa fue la especie más frecuente (87 %) y dominante (0.54 m2 · ha-1), Rhizophora mangle se presentó en el 75 %... |

| There is an international consensus, expressed in the Convention on Biological Diversity, World Summit on Sustainable Development, and Millennium Ecosystem Assessment, that biodiversity at all levels – genetic, species and ecosystem – have a critical role in sustaining livelihoods and human development. They underpin and make possible all forms of economic activity. Damage to components of biodiversity have economic consequences, the impacts of which fall most heavily on the poor. In few contexts is this as clear as in the case of mangrove ecosystems and their dependent human populations. Mangroves support livelihoods in providing habitat for food species, timber for dwellings, cooking and heat, and many other subsistence and commercial activities.... |
