A large part of Borneo jungle, almost the size of Singapore, may soon disappear under the waters of the Bakun dam, a multi-billion-dollar project in the finishing stages.
The dam, which forced thousands of indigenous people off their ancestral lands, has struggled through setbacks and delays since its approval in 1993, as well as fierce criticism over its environmental impact.
But even before the turbines of the 2.2 billion dollar hydro-electric facility begin to turn, activists have sounded the alarm over plans for 12 more mega-dams on Malaysia's half of Borneo which it shares with Indonesia.
Balan Balang, an elderly chief of the Penan tribe, sighs as he talks of the Murum dam, the first of the dozen dams envisioned for Sarawak state, which will drown the hunting grounds and burial sites of his people.
"This government is very bad. In the old days people would fight us using machetes or spears. But now they just sign away our lives on pieces of paper," said the headman, who sports the elongated earlobes distinctive to his tribe.
"My people never want to leave our place. We want to die in our place," he said, after a long journey from his rainforest home to seek help from indigenous lawyers in Miri, a coastal town in Malaysian Borneo.
Human rights activists are intent on avoiding a repeat of the botched relocation of some 15,000 indigenous people in the Bakun area who they say have made an unhappy transition to life in resettlement areas.
