Madagascar

This page is currently not sponsored. Click here to sponsor this page.
 
Area:587,041 km2
Name(s) in local language(s):Madagasikara


Madagascar is presently divided into 6 autonomous provinces (Faritany mizaka tena) and 22 regions (Faritra). This political division was created in 2004. A hierarchical division would be:
Fokotany (an older political unit; the smallest community unit, often abbreviated as FKT), Kaominina (= Commune), District (earlier called Fivondronana, abbreviated FIV, then also in a short period Departments), Faritra (Regions), and Faritany (Provinces).

An example: Take the Antsongombato gem mine - which recently has produced large and nice crystals of londonite/rhodizite. In the literature and on many labels it says: "Antsongombato, 25 km SW of Mahaiza, Betafo-Antsirabe area, Madagascar". This is correct but more a description.
Using the country's own geographical and political division, the locality should have been labeled: "Antsongombato gem mine, FKT Antsentsindrano, Andrembesoa Commune, Betafo District, Vakinankaratra Region, Antananarivo Province, Madagascar".

This (place name, FKT, Commune, District, Faritra, Province, Madagascar) should be the "right" hierarchy. This is very difficult to do in all cases, lacking detailed maps that reflect this division.
