The once mighty Mekong river is at a 50 year low in parts of Thailand and Laos.

Chinese companies have started construction on two hydroelectric dams in Cambodia, one on a tributary of the Mekong River.

Nations around the Mekong are meeting in Thailand to discuss the vital river's low water levels.

Al Jazeera's Wayne Hay went to northern Cambodia where the lack of water is affecting people's livelihoods.
