Geography

The Comoros are located in the Mozambique Channel to the north-west of Madagascar and facing Mozambique. These four volcanic islands, covering a total area of 2034 km², are:
  • Ngazidja (or Grande Comore): the largest island, with the capital of the Union of the Comoros, Moroni
  • Ndzwani (or Anjouan)
  • Mwali (or Mohéli)
  • Maore (or Mayotte): under French administration, and including
  • Pamanzi
    Pamanzi
    Pamanzi, known as Petite-Terre in French, is an island just off Mayotte, and is the second largest island after Mayotte itself.

In addition, between Madagascar and Mayotte, there is the Banc du Leven, a former island which is submerged these days.

"The affinity between the Comorian flora and the Madagascan flora is certain. The presence of the Banc du Leven, along about one hundred kilometres to the extreme north-west of Madagascar between the Montagne d'Ambre and the archipelago could partly explain this affinity. In fact, this bank with a tabular appearance presents coralligenous sediments which can be attributed to the presence of a coral reef

. In 1946, the islands were no longer administratively attached to Madagascar and formed a united and recognized administrative entity, an Overseas Territory of France (Territoire d'outre-mer or TOM).

In 1974, France organized a referendum for self-determination in the archipelago in which the population voted overwhelmingly in favour of independence. However, following the unilateral declaration of independence in 1975, France refused to recognise Comorian sovereignty over Mayotte, where a majority had voted no in the referendum. The three remaining islands formed the Etat Comorian, which later became the Federal Islamic Republic of the Comoro Islands.

In 1997, demands for increased autonomy on the islands of Nzwani (Anjouan) and Mwali (Moheli) led to the breakup of the Federal Islamic Republic. The government reformed under a new constitution in 2001 as the Union of the Comoros. The new constitution gave each of the three islands more autonomy than had been enjoyed previously. However, national authority over the islands was confirmed following the refusal of the President of Anjouan to hold free elections in 2008, and he was forced to flee by military intervention by troops of the Comorian Union and the African Union. The island continues its present form of confederal government albeit with minor changes approved in a 2009 referendum.

Mayotte, which had voted to retain French suzerainty in the 1975 referendum, expressed a wish to accede to the status of a département d'outre-mer (DOM) (Overseas Department) following another referendum

Geology

The Comoro Archipelago consists of volcanic islands. These volcanic islands like some of the high mountains in the north of Madagascar were formed in the Tertiary and Quaternary Eras. The island of Mayotte is the oldest one still above sea level and underwent three volcanic phases between 15 million and 500,000 years ago. The ages progressively decrease from east to west. The most recent island is that of Grande Comore, and its volcano, Karthala, is still active. The summit caldera is quite large, being approximately 3 x 4 km (1.9 x 2.5 miles) in size at the rim (2007).

Climate

The Comoro Archipelago enjoys a tropical maritime climate, characterized by slight daytime temperature variations throughout the year of around 26 °C (78.8 °F) at sea-level and by abundant precipitation: 2679 mm (105.5 in) a year. The average temperature of the sea water is 25 °C (77 °F).
There are two seasons in the Comoros: the hot and humid season flowing in from the north-west from November to April and the dry season from May to October. The climate on Mayotte is, nevertheless, noticeably warmer and drier. The climate is also characterized by important local variations in temperature and precipitation according to altitude, relief and the degree of exposure to the elements. Annual precipitation therefore varies in the region of 1000 to 6000 mm (39.4 to 236.2 in) and the absolute minimum of 0 °C (32 °F) is reached on the summit of Karthala.

The hot, dry season is caused by a vast low pressure area which extends over a large part of the Indian Ocean and Central Africa. This low pressure favours gusty winds and cyclone

s. The last cyclone was "Gafilo" which passed close to the Comoros on the 5th of March 2004 causing great material damage. During the hot and humid season it can rain as much as 200 mm (7.9 in) in twenty-four hours.
The dry season is calmer. The low pressure moves towards the continent of Asia (this is the Monsoon

 forms below the Comoros. This still does not prevent the islands from having a few gusts of wind, but their intensity is a lot less than during the hot season.

The two winds that bring the two different seasons are called the Kashkasi (in November) and the Kusi.

Flora and fauna

Several mammals are endemic to the islands. The Maki of Mayotte, a type of lemur which is only found on this island, is protected by French law, and by local tradition. A species of bat discovered by David Livingstone

 in 1863, previously abundant, has now been reduced to a population of about 1200 specimens, restricted to Anjouan and Moheli. A British preservation group sent an expedition to the Comoros in 1992, with the object of transporting some specimens to Great Britain, in order to form a reproducing colony.

Twenty-two species of birds are endemic to the archipelago, and seventeen of them only live on territories controlled by the Union; especially notable examples of these are the Karthala Scops-Owl, the Anjouan Scops-Owl and the Moucherolle of Humblot.

Partly as a result of international pressure during the 1990s, the government of the Union has begun to take greater care of the environment. Measures have been taken not only to preserve the rare fauna, but also to check the destruction of the environment, especially on Anjouan, which is densely populated. More precisely, in order to minimize the felling of trees for fuel, kerosene has been subsidized, and efforts are underway to replace the lost forest cover caused by the distillation of Ylang-ylang

No large African animals (elephants, giraffes, lions, crocodiles, zebras or antelopes) are found on the Comoros, despite the islands being relatively close to the Mainland.

 trees. The flora has only been poorly studied, France has however been made attempts on Mayotte to fill in the gaps. Efforts to preserve species are still not enough to save the richest zones, and disturbances of biotopes are expected to take place for many years to come.

Politics

The Comoro Archipelago is divided between:
  • The Union of the Comoros, a sovereign nation formed by the three islands of Grande Comore, Anjouan and Mohéli
  • Mayotte is a French Departmental Community and will become an Overseas Department of the French Republic (département d'outre-mer) in 2011. This island is claimed by the Union of the Comoros (which considers it to form part of its territory

     according to Article 1 of its Constitution), but it has chosen to remain French in numerous referenda that France has held to decide its position.


The United Nations General Assembly continued to condemn the French presence in Mayotte until 1994. France, however, used its power of veto in the UN to prevent the Security Council from passing a resolution condemning France.

The African Union judged the French presence on Mayotte to be illegal.

. It should become a Special Member State Territory at the moment that it is made a French Department.

The Comoros underwent a political crisis that started off in 1997 with the separatism on Anjouan.
The political authorities on the island had turned the population of the island against the central government, advocating at first reunification with France, and later a greater autonomy bordering on independence.

Since 2006, the President of the Union of the Comoros Ahmed Abdallah Sambi, originally from the island of Anjouan has been in open conflict with the authorities of Anjouan, a conflict which ended in a military landing of the National Army of Development in order to re-establish the authority of the Union on the island.
