This project threatens people and protected forest called the Central Cardamom Protected Forest, some 10,000 hectares of forest slated to be submerged by flood under the storage reservoir.
There are myriad issues related to this dam project - why on earth would Cambodia and/or their Chinese partners select a dam site in a protected area where traditional communities reside??? - there are Siamese crocodiles slated for relocation, and apparently the current botched efforts to move them, excluding village participation. This is important because the crocodiles are guardian spirits and the forest is full of ancestor protection spirits, and the land is ancestral land. It becomes very difficult for local people to convince their spirits to move when there is relocation like this.
Certainly there are elements of culture and resources and resource access lost completely due to dam flooding. However, perhaps international coverage, awareness, and local protest will help bring everyone to the table to look for new solutions. A story about the valley and its natural and cultural treasures is featured on a site called AsiaLIFE, an online tourism guide to Cambodia, Thailand, and Vietnam (why no Laos???).
