Urgent measures needed to address landslides and subsidence.

Given the complex situation of riverbank and coastal subsidence and erosion, Ca Mau province is urgently implementing many solutions, from immediate to long-term, to ensure the safety of infrastructure and the smooth flow of traffic for the people.

• Severe landslide at Dam Doi causes over 3 billion VND in damage.
• Urgently implement solutions to respond to landslides.
• Serious landslides have occurred on the road leading to Hung Thien Pagoda, threatening local residents' homes.
• Increased risk of landslides at the beginning of the rainy season.

The scene of a serious landslide that completely severed a rural road in Cai Nuoc commune.

In April alone, the province recorded 10 landslides and land subsidence incidents, concentrated in the communes of Dam Doi, Cai Nuoc, Tan Thuan, Dat Moi, and Tan Thanh ward. These incidents caused the subsidence of over 400 meters of rural roads, damaged 7 houses, and resulted in estimated property damage exceeding 4 billion VND.

The People's Committee of Cai Nuoc commune has erected warning signs and barriers in the dangerous landslide area to ensure the safety of people and vehicles.

Regarding the causes, Mr. To Hoai Phuong, Director of the Department of Agriculture and Environment of the province, said that landslide hotspots often occur in areas with deep riverbeds and strong currents. The large difference in tidal water levels creates enormous pressure on the riverbanks. In addition, weak geological foundations combined with the flow velocity in these river sections have eroded deep into the riverbanks, causing structural instability, leading to landslides and posing a potential risk of subsidence in the future.

Besides riverbank erosion, the impacts of climate change and rising sea levels are complicating coastal erosion. This is especially true in vulnerable sections such as: Bo De - Ho Gui, Kien Vang - Ong Ta, Ho Gui - Tan Tien, and Ap Hap - Gia Cao...

Coastal erosion is becoming increasingly complex.

Faced with the urgent situation, local authorities proactively activated on-site response plans. Mr. Nghiem Thanh Mien, Vice Chairman of the People's Committee of Cai Nuoc commune, said: "Immediately after the incident occurred, we assigned forces to the area to coordinate with the people in placing warning signs and barricading the dangerous area. For the sections of road that were broken, the commune mobilized manpower to temporarily reinforce them with piles and fill with black soil to ensure smooth traffic for the people."

Investing in coastal embankment projects is a key solution being implemented by authorities to address the increasingly complex issues of rising sea levels and erosion.

From a professional perspective, Mr. To Hoai Phuong further informed: For areas prone to riverbank erosion, the authorities will prioritize reinforcement using black soil and local timber species. " Soft embankment " solutions such as using coconut and mangrove piles combined with geotextiles, gabions, and stone mattresses at the base of the embankment are being implemented to protect the riverbanks and facilitate access and trade for students and residents.

Following the landslide, local authorities promptly reinforced and repaired the area, facilitating traffic flow for residents.

Regarding coastal erosion, the Department of Agriculture and Environment advises the Provincial People's Committee to report and propose to the Ministry of Agriculture and Environment to submit to the Prime Minister and other central ministries and agencies for financial support. This is an important resource for Ca Mau to invest in solid erosion control projects, protect the protective forest belt, and promote sustainable socio -economic development. At the same time, the province hopes that central specialized agencies will strengthen technical guidance on specific handling for each unique sub-area.
