The upper reaches of the Areng Valley are threatened by plans to build a hydroelectric dam that will inundate 10,000 hectares of the Central Cardamom Protected Forest which is habitat to at least 31 wildlife species that are globally threatened or nationally protected, including the endangered Siamese crocodile and Asian Arowana or Dragon Fish.
The dam will also flood nine Khmer Daeum villages and the homes of 1500 people, and up to 10,000 ha of indigenous lands including sacred forests covering over 500 ha. The communities living in the Araeng Valley depend on its productive rice paddies, plantations, fish and the harvesting of non-timber forest products from the nearby evergreen forests, for their survival, including
The Khmer Daeum have deeply-held links with the natural environment which connect them to village life through local Buddhist and animist beliefs. For example, the ‘Neak Ta’, or forest spirits, are believed to inhabit the forest, waterways and wildlife of the valley. Any forced migration of the Khmer Daeum from this valley will break this connection and will have deep social repercussions for a people who are spiritually linked to the forest and the valley.
Unlike other dams proposed for the region, this dam will flood a broad, flat valley that is densely populated and includes the richest agricultural land in southwest Cambodia as well as some of Cambodia’s rarest and most threatened wildlife. The environmental and social damage relative to the amount of power generated is therefore disproportionately high.
