Summary
[edit]DescriptionLAmou Darya (Khorezm, Ouzbékistan) (5609636905).jpg |
L'Amou Darya (Amou Daria) au niveau du pont de barges de Berouni. Long de 1437 Km, le fleuve Amou Darya prend sa source dans l'Hindou Kouch, et traverse les hauts plateaux du Pamir au Tadjikistan avant de se diriger vers la mer d'Aral à travers le désert. Il était en basses-eaux au moment de la prise de la photo en mars 2011. Appelé l'Oxus dans l'Antiquité, il a été traversé en 329 avant J.-C. par l'armée d'Alexandre, le roi de Macédoine, au moment de sa conquête de la Transoxiane (le pays au-delà du fleuve), auquel appartenait la Sogdiane dont Samarcande (appelée Marancanda dans l'Antiquité) était la capitale. L'Amou Darya a de tout temps constitué la frontière des mondes turc (désert de Kyzyl Koum en Ouzbékistan) et persan (désert de Kara Koum au Turkménistan). Il a changé de cours de nombreuses fois dans l'histoire. Son débit a beaucoup baissé depuis un siècle en raison des barrages et des canaux d'irrigation qui ont été créés à l'époque soviétique, en aval du fleuve, pour l'irrigation des champs et en particulier pour la culture du coton dont l'Ouzbékistan est un des grands producteurs mondiaux. L'assèchement de la mer d'Aral et la salinisation croissante des terres du pays sont des conséquences catastrophiques de cette politique d'irrigation mal maitrisée. |
