Mekong Dam Victims - Cambodia. People and motorbikes transported across the river. When the dam gates are closed it is possible to pass from one side of the river to the other without boat. At least 55.000 people living near the Sesan river in Cambodia's Ratanakiri and Stung Treng provinces continue to suffer due to lost rice production, lost fishing income, drowned livestock and damaged vegetable gardens, and so also great economical losses, because of the unpredictable floodings from the Yali Falls Dam on the other side of the border in Vietnam. To this day, flash floodings have caused the deaths of at least 39 villagers from various ethnic minority groups living along the river. Despite this, four other major hydropower projects are now in operation or under construction on the Sesan River in Vietnam. Known as "The Mother of Waters", more than 60 million people depend on the Mekong river and its tributaries for food, fresh water, transport and other aspects of daily life. The construction of big dams is now threatening the life of these people aswell as the vital and unique ecosystem of the river.
