Issues on Bakun - resettlement

Resettlement had involved the relocation of thepopulation of the upper Balui in the Belaga river

system.

The state of Sarawak through the State Planning

Unit had created a new section known as SpecialTask Section for Resettlement had been in charge

on the relocation of the indigenous people

More than 10 000 people from 15 different

communities have been forced to move to KampungSungau Asap and Kampung Sungai Koyan through a

codename of Operation Exodus.

At the resettlement area, people are suffering frompoverty, malnutrition, unemployment and adverse socio-economic conditions.

There are claims that the house units at the AsapResettlement Scheme were not in accordance with thatpromised in the relocation plan (Swain & Ang, 2004).

There were further claims that, the compensation havenot been fully fulfilled until present time. They werepromised 15 hectares per family before relocation insteadthe actual acreage allocated for them finally was only 3acres.

Due to deteriorating conditions of the resettlement area,some communities have moved back to their originalhomes in the inundation zone by building jelatong andstaying in the vicinity of the dam. They have establishednew villages near the dam fish, hunt and farm the land

nearby the dam.

Issues on Bakun - Safety

A group of citizen who residing downstream ofBakun Dam claimed that they have been kept in the

dark over the content of the Emergency Rescue Plan

(EPR).

The Sarawak Conservation Alliance for NaturalEnvironment (Scane) has called upon the

Issues on Bakun-Hydropower

Bakun Dam coincides the core of Sarawak Corridorof Renewable Energy (SCORE) in energy resources,

particularly in hydropower, coal and natural gas.

The estimated investment on the projects is RM94

bil and in 2030 an investment of RM300 willtransform Sarawak into an industrialized state and

energy hub of Borneo.

Therefore, the state needs to guarantee a

sustainable energy supply at a competitive rate inorder to encourage continuous inflows of

investments and organic growth


13/19

Adding up all the dams total combined capacity is4500 MW.

With the excessive power available there is an issue

where the power should go and how they can be

fully utilized for people. Suggestions are bound to leave the dams idle such

as Bakun Dam

Mitigation efforts - resettlement

The solution to social problems created must besolved through policy formulation and legal

frameworks

That must be complimented with the followings:

A population and baseline income survey as part offeasibility study

A detailed resettlement plan for peoples socio-economic

re-establishment

A relocation timetable correlated with advances in civilworks

A distinct budget for resettlement

Still not available in developing country

Mitigation efforts safety: Emergency Action

Plan (PNSB)

Level Alert Triggering event Action1 Low Spill expected Release reservoir water from the lower level of the draw-off

tower2 Medium High rainfall and spill

continues. Reservoir level

above maximum.Rapid increase in seepage

quantity and seepage water

is murky

Set up Emergency Task Team. Check with Jabatan Kajicuaca

on the forward weather forecasting.Consult SMHB for advice on rapid drawdown of reservoir.

Inform District Office of possible flooding close to the dam

and need for evacuation. Contact Civil Defense Dept. To

standby.

3 High High rainfall and spillcontinues. Reservoir level

above maximumDam failure considered

possible.

Contact emergency services and place them on full alert.Inform them of the need to establish emergency control

centre and evacuation of affected area as per inundation

maps.

4 Critical Dam failure likely Contact emergencies control centre to start full evacuation

Mitigation efforts excessive energy

The National Energy Policy 1979 was aimed toensure the provision of sufficient, secure and cost-

effective energy supplies by developing both

renewable and non renewable energy using least

cost options and diversification of supply sources

both within and outside Malaysia.

Therefore, excessive power of Bakun Dam should

be utilized accordingly to the energy needs inventory

of the policy, not only for industrial but also domestic.
