The government should therefore set up a national committee to deal with Bangkok's subsidence to prevent the capital from being submerged, the committee says.
The issue was raised at an NRC meeting Wednesday by Withaya Kulsomboon, chairman of the NRC panel responsible for drafting a report to address Bangkok's subsidence crisis.
Bangkok and adjacent provinces were only 0.5 to 2 metres above mean sea level and sinking, Mr Witthaya said. The longstanding and excessive use of underground water in areas without tap water supplies and the heavy weight of tall buildings were accelerating the subsidence.
