CanTho (VNA) – A seminar spotlighting the link between underground waterexploitation and subsidence issues in the Mekong Delta took place in Can Tho onMarch 21.
AssociateProfessor Nguyen Hieu Trung from the Can Tho University said subsidence couldlead to flood and shrinking arable lands, and affect local infrastructuredevelopment.
ProfessorPiet Hoekstra from the Netherlands-based Utrecht University noted thaturbanisation and a shift in land use are rapidly increasing water demand,resulting in large-scale exploitation of underground water sources in theregion.
PietHoekstra is director of the “Rise and Fall” project, a research programme aimingto enhance the capabilities of individuals and organisations to developsustainable strategies for dealing with groundwater extraction, land subsidenceand salt water intrusion in the Mekong Delta.
Seminarparticipants heard recent surveys from the project, which showed that the region’srural areas subside between 1 and 2 cm per year, while the figure for urban andindustrial areas hits 2.5 cm per year.
Theresearch attributed the rapid subsidence to rampant exploitation of undergroundwater since the 90s of the 20th century. - VNA
