Mayotte is an archipelago in the Indian Ocean located in the biogeographical area of the Comoros Archipelago, at the heart of the Mozambique Channel and close to Madagascar. It consists of a main island, Grande-Terre (or Maore), a smaller island, Petite-Terre (or Pamanzi), and several islets around these two. Mayotte has an area of 374 km² and a coastline of length 185.2 km. Its entire EEZ of 70 000 km² has been designated as an MPA. The Mayotte archipelago is surrounded by a coral barrier reef, which shelters a lagoon and marine reserve that are popular diving destinations.
The lles Eparses
The lles Eparses are a collection of French overseas island territories in the Western Indian Ocean managed by the French Southern and Antarctic Lands since February 2007. lles Eparses are composed of the following islands: Europa, Juan de Nova and Glorieuses archipelago (Grande Glorieuse, Roches Vertes and Ile du Lys) in the Mozambique Channel, Tromelin north of La Reunion and the barely emerged coral reef of Bassas da India. Bassas da India covers total land area of 80km2; Europa Island – 28km2; Glorioso Islands – 5 km2; Juan de Nova Island – 4.4 km2 and Tromelin
Island a total 1 square kilometre . The associated territorial marine waters represent a total of more than 640,000 km2 (approximately 6% of the French maritime territory). All islands except Juan de Nova were classified as nature reserves in 1975.
France has appointed a Focal Point to the Nairobi Convention to help coordinate efforts to protect, manage, and use the Western Indian Ocean at the national level.
