Mekong Delta.

Mekong River Delta (Vietnam & Cambodia); Vietnam; Cambodia

The Mekong Delta, the final downstream portion of one of the longest rivers of the world, extends to the southern tip of Vietnam and Cambodia on a triangular plain of approximately 21,236 square miles (approximately 55,000 square kilometers). It is the third-largest deltaic plain in the world, after the Amazon River delta and that of the Ganges-Brahmaputra system. The delta includes a wide variety of ecosystems. It faces several key environmental problems, mainly related to largely unsustainable economic activities and to its historical background.
