Mangroves are under increasing pressure as terrestrial forests dwindle, Agricultural lands are fully occupied elsewhere leading to migration into once undisturbed mangroves. The reduction in terrestrial forest cover has led to more and more harvesting of mangrove timber which, at the same time, is increasingly prized for its construction versatility, value as charcoal and resistance to parasites.

Dans le domaine des infrastructures, le bilan global est positif. De nombreux ouvrages ont été inaugurés et le réseau routier national s'est nettement amélioré, notamment le réseau reliant la capitale aux quatre principaux ports du pays et les autres routes nationales, desservant les régions productrices de cultures à l'exportation. L'amélioration des cultures de rente et des filières d'exportation a porté sur la diversification horticole, la normalisation agricole, la promotion des cultures de rente et la surveillance des pêches. Les programmes de structuration du monde rural ont permis de renforcer l'environnement productif du monde paysan (micro finances, services agricoles) et ont facilité l'émergence de leaders dans le milieu rural.

Some game reserves boast more than one ecosystem, sometimes even five, ranging from valley bushveld, savannah grassland and fynbos to riverine forest and acacia woodland; this provides a dramatic improvement on the types of wildlife that are present and the numerous species of birds that thrive on in these environments. Nigeria is blessed with rich and unique array of ecosystems, and a great variety of wild fauna and flora.

L’identification, la quantification et la cartographie des facteurs de changement représentent une étape importante dans le processus de planification de la conservation et pour la gestion des écosystèmes. Dans cette étude, nous avons identifié 15 facteurs de changement anthropiques qui peuvent être regroupés en 8 catégories : pêche industrielle pélagique, pêche côtière, pêche à pied, sédimentation terrigène, pollution des bassins versants par les activités urbaines et agricoles, dégradations locales dues aux activités urbaines, tourisme et transport maritime. Les facteurs de changement ont été cartographiés en utilisant plusieurs techniques d’analyse spatiale dont celle de la logique floue, de l’analyse de voisinage et l’analyse d’image satellite océanographique. Les 8 catégories de facteurs de changement ont ensuite été classées et pondérées par des experts de la région réunis au cours d’un atelier, sur la base de leur impact potentiel sur les cinq principaux types d’habitats : récifs coralliens, mangroves, herbiers, autres habitats côtiers et habitats pélagiques profondeur > 200m, distance de la côte > 25km). Afin de développer un système de pondération valide, nous avons utilisé un processus analytique de hiérarchie basé sur la comparaison par paires de facteurs de changement. L’objectif était d’étudier une partie des facteurs de changement (FdC) dans l’OIO et de cartographier leur distribution spatiale et leur intensité en se basant sur des données de télédétection et socio-économiques et en utilisant les techniques de modélisation spatiale des SIG. La technique de logique floue et l’analyse d’images satellites ont été utilisées pour cartographier les FdC. La logique floue est une orme d’algèbre utilisant une gamme de valeurs comprises entre « vrai » et faux » qui est appliquée dans la cartographie de données imprécises ou peu sûres (Ross 2004). Les données sont codées de 0 à 1 rapportant à une fonction d’appartenance floue.

The application of this approach in Madagascar would make it possible to test the validity of the classical divisions and circumscribe alternative ones, and to determine the current extent of natural and anthropogenic formations (principally secondary grasslands, often called \"prairies\", \"pseudosteppes\", etc., which cover about three quarters of the country). Before the arrival of man, the original woody vegetation types in the drier west (forest, woodland, bushland, etc.) were in a fragile equilibrium and could quickly have been converted to secondary grassland by fires; in the moister center more active human intervention (clearing) was likely required to alter the vegetation. Contrary to recent claims, native grasslands were not widespread immediately prior to the arrival of humans, but were probably restricted to small patches.
