- W2523996853 abstract "T study, realized in July 2014 in the eastern region of Madagascar, in Toamasina give an example of a suitable methodology for the diagnosis of marine and coastal ecosystems in relation to investment projects. Two cases were studied: the mining project (case Ambatovy) and port infrastructure (port of Toamasina). The eastern region was chosen as the site of study because it brings the typical cases of what is happening in the Big Island in terms of potential impacts of investments project on coastal and marine ecosystems. For Ambatovy project, three sites were chosen which are reef “Nosy Faho”, “Ile aux Prunes”, and the outlet of Ambatovy project. For port’s infrastructure, two sites were selected whose reef “Bain des Dames” and the Great Reef of Toamasina. Several indicators were assessed, among other: the percentage of coral coverage of the substrate and the existence of bio-indicator species to get a sense of the vitality of reefs, concentrations of heavy metals in water, sediments and biota to assess the change in environmental quality, finally the availability of fishery resources through species composition, abundance and biomass of commercial fish. The results obtained during this intervention showed that there is not yet a significant variation in percentage coral reef cover inside all followed site, since 2008, date when Ambatovy project’s assessment started. For the Great reef and the reef of “Bain des dames”, a phenomenon of advanced silting is found, caused by human activities that are made at these sites, fragmenting and destroying coral colonies." @default.
