Hundreds of Malaysian indigenous people have blockaded the construction site of a new dam which is set to force them from their homes in Sarawak state on the island of Borneo, activists have said.
Indigenous Kenyah, Kayan and Penan people began blocking the main entry road to the Baram dam on Wednesday afternoon, and continued the blockade on Thursday.
The Baram dam is the latest in a series of controversial hydroelectric mega-dams planned by the Sarawak provincial government as it pushes economic development in one of Malaysia's poorest states.
While the Baram dam is expected to generate 1,200 megawatts of power, activists claim it will flood 400 square kilometres of rainforest (154 square miles) and displace about 20,000 tribespeople.
Peter Kallang, chairman of the NGO, Save Sarawak's Rivers Network, said in a Facebook posting late on Wednesday that they were "camping at the blockade to show their determination against the construction of this bloody dam" after being inspired by a blockade that began last month against the filling of the nearby Murum Dam.
"The call is to stop the project and all activities related to the construction of the dam because State-owned Sarawak Energy (SEB) is already starting soil investigation," The group's vice-chairman Raymond Abin told AFP news agency.
The government of resource-rich Sarawak says it hopes a plentiful supply of hydropower from the state's powerful jungle rivers will attract new industries.
SEB, in charge of building the dam, has insisted that displaced villagers are being compensated fairly. It could not be reached for immediate comment on the Baram blockade.
Swiss-based activists at the Bruno Manser Fund, which has repeatedly accused Sarawak's longtime Chief Minister Taib Mahmud of corruption, said that the protests would add to scrutiny on Malaysia's human rights record.
"The latest blockades add pressure on the Malaysian government ahead of a key UN meeting in Geneva. Malaysia's human rights records will be discussed tomorrow by the Human Rights Council on the occasion of a country review," they said in a statement on Wednesday.
Taib has faced mounting accusations of enriching himself and cronies through a stranglehold on the state's economy, charges which he denies.
The province is home to the already-operating 2,400-megawatt Bakun dam, which Transparency International has condemned as a graft-plagued ecological catastrophe.
Despite Bakun providing more than double Sarawak's current energy needs, a series of other dams are in the works.
The Malaysian federal government revealed early this month it had to pay $133m in compensation to suppliers due to delays in the $2.3bn Bakun project, a rare official acknowledgement of problems in the highly controversial flagship hydropower initiative.
