La faune et la flore malgaches possèdent un taux d’endémicité très élevé : 80 % des espèces animales et 90% de la végétation n’existent que sur l’île. À l’échelle mondiale, Madagascar est représentative d’une mégadiversité impressionnante. En effet, Madagascar, île de l’océan Indien occidental (COI) fait partie des 34 hot-spots de la biodiversité mondiale. C’est un label plutôt flatteur car il fait de la Grande île l’une des plus importantes régions en termes d’habitats rares et d’espèces phares. La conservation de ces richesses naturelles est ainsi inscrite dans l’agenda international. La mise en place d'aires protégées marines figure parmi les priorités de la politique de Madagascar en matière de préservation de l'environnement. Au vu de l’importance de ces zones marines et côtières et dans le but de les préserver face aux menaces et pressions d’origine anthropique et naturelle, Madagascar s’est résolument investie dans la création et la mise en place d’aires marines protégées et de réserves marines afin de contribuer au bien-être des communautés locales qui en dépendent. La première aire marine protégée a été officiellement créée en 1989 avec le parc marin de Nosy Antafana intégré à la Réserve de Biosphère de Mananara Nord, suivie par les trois parcelles marines du Parc National de Masoala. Vingt ans après le premier parc marin, de nouvelles aires marines protégées et réserves marines ont été créées ou sont en voie de création dans l’attente de l’obtention de leur statut définitif1. Les aires protégées sur les rivages et dans les eaux malgaches sont le fruit d’un travail réalisé dans un étroit partenariat avec les communautés locales pour assurer une bonne gestion des parcs dont le contrôle et la surveillance, le suivi écologique et l’application des régulations du parc et le développement des activités liées au tourisme.amp_4_2010_ddAires, Marines, Protection, Madagascarfeaturesurn:x-ogc:def:crs:EPSG:432643.06967321723259 -25.4569646757650.47724461161199 -11.98249895707104https://acma.africanmarineatlas.org/catalogue/csw?request=GetRecordById&service=CSW&version=2.0.2&id=eda23369-1898-493d-a62b-ab66f30b0c57&outputschema=http%3A%2F%2Fwww.opengis.net%2Fcat%2Fcsw%2Fcsdgm&elementsetname=fullgeonode:madagascar_tr_route_dd_sagaLes routes nationales avancent bien dans les zones goudronnées. Il manque en général les obstacles de type gués et radiers. Il y a de petites différences entre les longueurs constatées dans OSM et les chiffres gouvernementaux. Pour les N6 et N7, il manque certainement quelques longueurs dans les villes terminus mais ça n'explique pas toute la différence. Certains virages tracés sommairement dans OSM peuvent aussi réduire le total. Enfin, les chiffres gouvernementaux ne sont pas fiables non plus. Le Document de stratégie pays pour Madagascar au titre du 9ième FED a adopté comme secteurs prioritaires de financement pour la période 2000-2007: les infrastructures routières et le développement rural. Les interventions, initialement déployées dans tout Madagascar, ont été concentrées depuis 2002 sur les régions du Sud (Fianarantsoa et Toliara), zones identifiées alors comme les plus pauvres. 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. Les programmes de développement local ont reflété, quant à eux, une évolution importante de la coopération avec la CE, des micro réalisations vers le financement direct et l'aménagement du territoire local.

Et comme cette population n’est urbanisée qu’à environ 15%, on comprendra que les grandes agglomérations soient rares. Les plus importantes sont Antananarivo, la capitale nationale et les cinq chefs-lieux des anciennes Provinces, soit par ordre alphabétique, Antsiranana, Fianarantsoa, Mahajanga, Toamasina et Toliara. Aux temps coloniaux, bien avant la suppression des six provinces et leur remplacement par les vingt-deux régions actuelles, le nom de ces six villes que les colonisateurs ne parvenaient pas à prononcer avait été changé en Tananarive, Diégo Suarez, Fianarantsoa, Majunga, Tamatave et Tuléar, des noms qui ont toujours été rejetés par les autochtones. Ces villes ont fini par retrouver leur identité initiale peu après l’indépendance en 1960. Avec le grand changement politique de 2002 et la mise en place de la décentralisation, elles ont presque toutes perdu une bonne partie de leur importance administrative et politique, mais non leur poids démographique et économique. C’est d’ailleurs ce dernier facteur qui nous a conduit à leur ajouter deux ports : l’un à l’extrême Sud-est qui se développe énormément en raison de l’exploitation et l’exportation de l’ilménite, minerais dont on extrait le titane et le second dans le creux de la côte ouest, avec un arrière-pays prometteur au plan charbonnier (Sakoa) et pétrolier (Bemolanga). Il s’agit respectivement de Taolagnaro, nom original de Fort Dauphin, et de Morondava.madagascar_localites_dd_sagafeaturesMadagascarVilles, villages, localites, Madagascarurn:x-ogc:def:crs:EPSG:432643.22848450372746 -25.5704699441409450.4754880363888 -11.963613701983933https://acma.africanmarineatlas.org/catalogue/csw?request=GetRecordById&service=CSW&version=2.0.2&id=2df256d1-f528-4257-ae69-0c2001d76e28&outputschema=http%3A%2F%2Fwww.opengis.net%2Fcat%2Fcsw%2Fcsdgm&elementsetname=fullgeonode:madagascar_rails_sagaL’âge des chemins de fer à Madagascar risque fort d’avoir été bref. De 1901, qui vit l’ouverture du premier chantier, à 1936, un embryon de réseau de quelque 860 kilomètres fut constitué. Mais, en 2001 sur les 4 lignes qui le composaient, seul le FCE (Fianarantsoa-Côte-Est, 163 km) était encore animé par un modeste convoi quotidien, alors même que le problème des transports était plus aigu que jamais. Depuis, le TCE (Tananarive-Côte-Est, 369 km) a repris du service pour l’acheminement de pondéreux, les hydrocarbures principalement. Mais la tentative de remise en service du TA (Tananarive-Antsirabe, 158 km) s’est soldée par un déraillement de bien mauvais augure. Dans le contexte politique et idéologique actuel qui privilégie la privatisation de toutes les activités économiques, l’avenir des chemins de fer malgaches est plus qu’incertain. 2 Or incriminer la mauvaise gestion des Républiques successives depuis 1960 n’est pas une explication suffisante. Car une analyse remontant aux origines de ces voies ferrées fait apparaître clairement que l’entreprise a été dès l’origine mal pensée et encore plus mal exécutée. Le calcul économique resta déficient, ce qui rendait illusoires les espérances de développement, elles-mêmes obérées par de sévères contraintes, qu’il s’agisse des conditions de financement, du parasitisme d’intérêts particuliers ou d’effets pervers source de blocage économique. Et surtout, la réalisation fut menée au prix d’un coût social et humain très élevé, qui éclaire notamment les origines de l’insurrection de 1947 dont les chemins de fer furent les axes et la cible, et au-delà, l’hostilité des populations à une modernité toujours perçue comme oppressive.madagascar_rails_sagaCemin de fre, transport, MadagascarCemin de fer, transport, Madagascarfeaturesurn:x-ogc:def:crs:EPSG:432647.03845589099999 -22.14862252352659849.40401836109758 -17.6418209445266https://acma.africanmarineatlas.org/catalogue/csw?request=GetRecordById&service=CSW&version=2.0.2&id=49edd26a-d539-4d27-8063-dcb4be15f450&outputschema=http%3A%2F%2Fwww.opengis.net%2Fcat%2Fcsw%2Fcsdgm&elementsetname=fullgeonode:test_recif_sw_mr_ddMadagascar’s west coast contains the greatest diversity of coral reefs. Here, a great “river” of seawater, the Agulhas Current, warms the shallows over a broad continental shelf, and a variety of reef types--including fringing, barrier and bank reefs--have developed. The world’s third-largest network of coral reefs lies off the southwestern coast. Called the Toliara or Tulear reef system, this tract spans close to 200 miles between the vicinity of the Mangoky River mouth to the north and the community of Androka to the south. According to the "World Atlas of Coral Reefs," the Tulear reefs sport at least 130 species of stony coral and 700 kinds of fish. Andavadoaka-area reefs, only recently systematically surveyed, are also species-rich. But, like many coral systems worldwide, they have suffered mightily from bleaching, wherein coral polyps lose their symbiotic algae. In 2006, National Geographic reported that a survey of the reefs off the southwestern coast by the groups Blue Ventures, and the Wildlife Conservation Society suggested that some corals there might be resistant to bleaching.Land Surface, Topography, LandformsLand Surface, Topography , conservationtest_recif_sw_mr_ddLand Surface, Topography, reefsfeaturesMadagascarurn:x-ogc:def:crs:EPSG:432643.20351962256978 -25.27625860054443450.46019562882542 -13.23746876941507https://acma.africanmarineatlas.org/catalogue/csw?request=GetRecordById&service=CSW&version=2.0.2&id=d399d472-8ffd-481c-aa38-24cbc12a59d9&outputschema=http%3A%2F%2Fwww.opengis.net%2Fcat%2Fcsw%2Fcsdgm&elementsetname=fullgeonode:madagascar_dcw_rivers_sagaMadagascar montre une très grande hétérogénéité dans la répartition et le potentiel de ses ressources en eau.

Delimitation of phytochoria based on the distribution patterns of taxa provides an objective framework for comparing and mapping vegetation types using a simple physiognomic classification. 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. Today, human impacts can be seen in all Malagasy vegetation types, even supposedly undisturbed "native" forest.Land Surface, Landforms, vegetationvegsimpfeaturesMadagascarurn:x-ogc:def:crs:EPSG:432643.238014221191406 -25.3997669219970750.459938049316406 -11.95983600616455https://acma.africanmarineatlas.org/catalogue/csw?request=GetRecordById&service=CSW&version=2.0.2&id=b549f013-59ec-438f-b338-914d91dd0bab&outputschema=http%3A%2F%2Fwww.opengis.net%2Fcat%2Fcsw%2Fcsdgm&elementsetname=fullgeonode:reef_clip_madaThe dataset represents the Madagascar regional distribution of warm water coral reefs.

They are rare on continental margins that have extremely steep continental slopes or escarpments. Submarine canyons are so called because they resemble canyons made by rivers on land. A submarine canyon is a sharply angled valley on the floor of the ocean of the continental incline. Submarine canyons act as conduits to bring sand-sized sediments from the continental margins to the deep sea. During lowstands of sea level, rivers empty directly into the heads of many Atlantic canyons.

Simply put, wetlands are in-between areas that have something of both dry uplands and open water environments: they are neither land nor water - they are a transition zone, which is what makes them so interesting. Wetlands have both upland and aquatic characteristics, and, thus, they often have a richer flora and fauna than other environments.

Many game reserves are located in Africa. Most are open to the public, and tourists commonly take sightseeing safaris. A game reserve is more than just a piece of land or a place to keep wildlife; it is a place where ecosystems are protected and conservation is a key. Indigenous wildlife in its natural habitat makes for an ideal situation as this helps in providing an environment where growth in numbers at a natural rate can occur. 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.

They are grass-like flowering plants that live completely submerged in marine and estuarine waters. Many species leaves are long and narrow, and these plants often grow in large meadows which look like grassland: in other words many of the species of seagrasses superficially resemble terrestrial grasses of the family Poaceae. The canopy of seagrass protects smaller marine animals, including the young of such species as drums, sea bass, snappers and grunts from larger predators. Some animals, such as manatees, urchins, conches and sea turtles, eat seagrass blades. Other animals derive nutrition from eating algae and small animals that live upon seagrass leaves. Bottlenose dolphins and a variety of wading and diving birds also use seagrass beds as feeding grounds. Seagrass-based detritus formed by the microbial breakdown of leaves and roots is also an important food source. The seagrass dataset has been compiled by UNEP-WCMC in collaboration with Dr Frederick T. Short, University of New Hampshire, USA to show the global distribution of seagrass species. This dataset has been created from multiple sources and was used in the creation of the World Atlas of Seagrasses(2003).

Les plus abondantes sont la tortue verte (Chelonia mydas) et la tortue imbriquée (Eretmochelys imbricata) pour lesquelles l’OIO regroupe des sites de pontes parmi les plus importants au monde. De nombreuses plages et sites autour de Madagascar sont fréquentés par les tortues vertes. Les Seychelles et les îles de Nosy Hara et Radama au nord-ouest de Madagascar sont des zones importantes pour l’alimentation des tortues imbriquées. Les îles du canal du Mozambique (Europa, Juan de Nova et Glorieuses) ainsi que Moheli et Mayotte sont très fréquentées par les juvéniles de tortue imbriquée.(Source: RAMP-COI, 2011)Biology, Reptiles, Madagascar, Biospheresites_ponte_eretmochelys_imbricatafeaturesMadagascarurn:x-ogc:def:crs:EPSG:432640.359036342531994 -22.33976070887305855.54139793687514 -4.430079610119688https://acma.africanmarineatlas.org/catalogue/csw?request=GetRecordById&service=CSW&version=2.0.2&id=18f8f0e0-4ec3-441f-9475-c76eafa595b3&outputschema=http%3A%2F%2Fwww.opengis.net%2Fcat%2Fcsw%2Fcsdgm&elementsetname=fullgml:Envelopegml:Pointgml:LineStringgml:PolygonLessThanGreaterThanLessThanEqualToGreaterThanEqualToEqualToNotEqualToLikeBetweenNullCheckabsabs_2abs_3abs_4acosAddCoveragesAffineAggregateAndareaarea2AreaGridarrayasinatanatan2attributeCountBandMergebandsBandSelectBarnesSurfacebetweenboundaryboundaryDimensionboundedByBoundsbufferBufferFeatureCollectionbufferWithSegmentsCategorizeceilcenterLinecentroidclassifyClassifyByRangeClipCollectGeometriesCollection_AverageCollection_BoundsCollection_CountCollection_MaxCollection_MedianCollection_MinCollection_NearestCollection_SumCollection_UniqueConcatenatecontainsContourcontrastconvertconvexHullConvolveCoveragecosCountCoverageClassStatsCropCoveragecrossesdarkendateDifferencedateFormatdateParsedensifydesaturatedifferencedimensiondisjointdisjoint3Ddistancedistance3Ddouble2boolDownloadDownloadAnimationDownloadEstimatorDownloadMapendAngleendPointenvenvelopeEqualAreaEqualIntervalequalsExactequalsExactToleranceequalToexpexteriorRingFeatureFeatureClassStatsfloorfootprintsgeometrygeometryTypegeomFromWKTgeomLengthGeorectifyCoverageGetFullCoveragegetGeometryNgetXgetYgetzgrayscalegreaterEqualThangreaterThanGridGroupCandidateSelectionHeatmaphslidIEEEremainderif_then_elseImportinin10in2in3in4in5in6in7in8in9inArrayInclusionFeatureCollectionint2bboolint2ddoubleinteriorPointinteriorRingNInterpolateintersectionIntersectionFeatureCollectionintersectsintersects3DisCachedisClosedisCoverageisEmptyisInstanceOfisLikeisNullisometricisRingisSimpleisValidisWithinDistanceisWithinDistance3DJenksJifflejsonArrayContainsjsonPointerlabelPointlanguagelapplylengthlessEqualThanlessThanlightenlistlistMultiplylitemliteratelogLRSGeocodeLRSMeasureLRSSegmentmapGetmaxmax_2max_3max_4minmin_2min_3min_4mincircleminimumdiameterminrectanglemixmoduloMultiplyCoveragesNearestNormalizeCoveragenorthFixnotnotEqualTonownumberFormatnumberFormat2numGeometriesnumInteriorRingnumPointsoctagonalenvelopeoffsetOroverlapsPagedUniqueparameterparseBooleanparseDoubleparseIntparseLongpgNearestpiPointBufferspointNpointOnLinePointStackerPolygonExtractionpolygonizePolyLabellerpowpropertyPropertyExistsQuantileQueryqueryCollectionquerySinglerandomRangeLookupRasterAsPointCollectionRasterZonalStatisticsRasterZonalStatistics2RecodeRectangularCliprelaterelatePatternreprojectReprojectGeometryrescaleToPixelsrintroundround_2roundDoublesaturateScaleCoveragesdo_nnsetCRSshadesimplifysinsizeSnapspinsplitPolygonsqrtStandardDeviationstartAnglestartPointStoreCoveragestrAbbreviatestrCapitalizestrConcatstrDefaultIfBlankstrEndsWithstrEqualsIgnoreCasestrIndexOfstringTemplatestrLastIndexOfstrLengthstrMatchesstrPositionstrReplacestrStartsWithstrStripAccentsstrSubstringstrSubstringStartstrToLowerCasestrToUpperCasestrTrimstrTrim2strURLEncodeStyleCoveragesymDifferencetantinttoDegreestoRadianstouchestoWKTTransformTransparencyFillunionUnionFeatureCollectionUniqueUniqueIntervalVectorToRasterVectorZonalStatisticsverticeswithin
