Yea Buthea, 50, (foreground) and his brother Yen Bunsong, 35, (background), stand on the edge of their family property. The Mekong's banks are eroding at the rate of roughly 4-5 meters per year in the area, and the brothers will have to dismantle their home and move within months or else it will collapse into the water below.
