The Scattered Islands in the Indian Ocean (French: Îles Éparses or Îles Éparses de l'océan Indien) consist of four small coral islands, an atoll, and a reef in the Indian Ocean, and have constituted the 5th district of the French Southern and Antarctic Lands (TAAF) since February 2007. They have never had a permanent population. Two of the islands—Juan de Nova and Europa—and the Bassas da India atoll lie in the Mozambique Channel west of Madagascar, while a third island, Tromelin, lies about 450 kilometres (280 mi) east of Madagascar and the Glorioso Islands lies about 200 kilometres (120 mi) northwest of Madagascar. Also in the Mozambique Channel is the Banc du Geyser, a reef under French control claimed by Madagascar since 1976. France and the Comoros view the Banc du Geyser as part of the Glorioso Islands.
The islands have been classified as nature reserves. Except for Bassas da India, they all support meteorological stations: those on the Glorioso Islands, Juan de Nova, and Europa Island are automated. The station on Tromelin Island, in particular, provides warning of cyclones threatening Madagascar, Réunion, or Mauritius. Each of the islands, except Bassas da India and Banc du Geyser, has an airstrip of more than 1,000 metres (3,300 ft).
Mauritius, the Comoros, and Madagascar dispute France's sovereignty over the islands. Mauritius claims Tromelin and argues that the island, discovered by France in 1722, was not ceded by the treaty of Paris in 1814. Madagascar claims sovereignty over Glorioso Islands (Banc du Geyser included) despite the islands not having been a part of Malagasy Protectorate, but rather a part of colony of Mayotte and dependencies, then a part of French Comoros that had become a separately administered colony from Madagascar in 1946. The Comoros claims the Glorioso Islands (Banc du Geyser included) too, as a part of the disputed French region of Mayotte. Madagascar claims Juan de Nova, and Europa and Bassas da India since 1972. Seychelles claimed a part of Scattered Islands too before the France–Seychelles Maritime Boundary Agreement.
