CAN THO (VNS) — Experts from Utrecht University of the Netherlands and Can Tho University held a seminar yesterday to discuss solutions to landslide and land subsidence in the Cuu Long (Mekong) Delta.
At the seminar, Prof Dr Le Van Tri, head of the Institute of the Mekong Delta Climate Change Research, said that the risks of landslides and subsidence, saltwater intrusion and extraction of groundwater resources were increasing sharply in this area. He pointed out that there was a lack of close research on these issues.
Tri added that subsidence had damaged infrastructure, increased the risk of flooding, threatened agricultural land and caused erosion in coastal areas, as well as changed the flow of river systems.
Prof Tom Kompier, a representative of Utrecht University, said that experts of both universities jointly carried out several studies to analyse the area's geological condition and gave specific solutions to limit the subsidence.
Several projects have been implemented, such as construction of roads, flood-control dikes, water supply units as well as wastewater treatment systems, Kompier added.
However, he warned that all these solutions are not feasible if the awareness of people is not raised.
People need to know that water is not an infinite resource, especially groundwater, and that it is necessary to use it in the right way, he added.
Kompier also said that uncontrolled exploitation of groundwater resources will lead to land subsidence, drought and poor harvests. — VNS
