VietNamNet Bridge – With increased land subsidence, HCM City needs to build dykes like the ones used in the Netherlands to prevent tides and floods, experts have urged.

HCM City Mayor Nguyen Thien Nhan said MONRE has surveyed the soil and terrain conditions at 17 points in HCMC. The monitoring shows continued subsidence at all points. Subsidence of up to 30 cm in the last 10 years has been found in two places.

“If the soil sinks by 1 cm per annum and the sea water level rises by 0.5 cm per annum, or 1.5 cm in total, the difference between the earth surface and sea water level would be up to 45 cm. If so, the problem will be very serious,” Nhan said. Tiếp tục đọc “Will HCM City build dykes similar to those used in the Netherlands?” →

VietNamNet Bridge – The sustainable development of the Cuu Long (Mekong) Delta faces many threats, especially the rising sea level, worsening land subsidence and declining sedimentation, Dr Le Xuan Thuyen of the University of Natural Sciences has warned.

A severe landslide that occurred along a bank of the Tien River in Thanh Binh District in the Mekong Delta province of Dong Thap last April.

Speaking at a seminar last Thursday in HCM City titled “Challenges for sustainable development of the Mekong Delta,” Thuyen said: “The delta is formed by sediments and fairly steady sea levels. Now the two elements are no longer present and so the delta is facing an uncertain future.” Tiếp tục đọc “Land subsidence, rising seas threaten Mekong Delta” →

BÌNH THUẬN — Extreme weather conditions resulting in a complex tide phenomenon, landslides and sea erosion are threatening coastal areas in central Bình Thuận Province, authority officials and local people have said.

Mai Kiều, director of the provincial Department of Agriculture and Rural Development, said this week that landslides and erosion constantly hitting the province’s 10km coastline over the past 10 years had caused extensive damage to local life.

Tuy Phong District was the hardest hit area, with hundreds of households in the communes and townships, including La Gi, Tân Phước, Vĩnh Tân and Tiến Thành, faced with the high possibility of having to flee their homes.

Landslides and erosion have been increasingly impacting agricultural production; infrastructure, including roads and sea dykes; and particularly many protective forests.

The sea has completely destroyed over 450m of sea dykes and damaged nearly 300 houses and dozens of hectares of forest in the two areas of La Gi and Tân Phước alone, according to Kiều.

Last month, sea tides and waves 3-4m high devastated 150 households in Vĩnh Tân Commune, with some 300m of coastline completely eroded.
