Strengthening dikes, not being passive in the face of natural disasters

Faced with the increasingly clear impacts of climate change and extreme natural disasters, Quang Ninh province is urgently completing the Project to improve the safety of the dike system to adapt to climate change in the period 2025-2030, with a vision to 2050. The project aims to synchronously invest in the dike system in the whole province, associated with the protection and development of mangrove forests, creating a solid foundation for sustainable development and enhancing the ability to proactively respond to unpredictable climate changes.

The Ha Nam dike section running through Lien Hoa ward has been solidly invested in to ensure safety.

Dong Trieu Ward is one of the localities with a large and complex dike system in the province, with 7 dike routes with a total length of nearly 20km, playing an important role in protecting residents, agricultural production and riverside infrastructure. However, due to the impact of extreme weather, storms and long-term use, many dikes have degraded, posing potential risks of insecurity, especially during the rainy season. Some dike sections have low peak elevations, steep slopes, weak foundations, sandy soil, do not meet technical standards, and are prone to seepage, overflow and landslides when the river water rises. Typically, many locations on the Tan Viet - Duc Chinh, An Bien, Binh Duong - Dong Mai routes have not been upgraded, and their storm resistance capacity only reaches level 6 to level 9, posing great risks when there are high tides or strong storms.

After the impact of storm No. 3 in 2024, combined with high tides and discharge from hydroelectric reservoirs, many sections of the dyke in Dong Trieu ward experienced landslides and water seepage, directly affecting the safety of residents. In early October 2025, the rising water level of Kinh Thay River caused many residential areas outside the Hong Phong dyke to be flooded, disrupting production and daily life. Along with that, the narrow dyke surface, on average only 2-2.5m, some sections only 1.5m, making patrolling, inspection and deployment of rescue forces difficult.

As the central locality in the western region of the province, with an area of ​​over 40km² and more than 43,700 people, Dong Trieu ward is developing strongly in the direction of industry, services, urban areas, and at the same time is a high-tech agricultural area. In that context, ensuring the safety of the dike system is not only a task to protect people's lives but also a fundamental factor for sustainable socio -economic development.

Mr. Le Van Hung, Vice Chairman of Dong Trieu Ward People's Committee, said: Faced with this reality, Dong Trieu Ward has proactively prepared a report, proposing the province to include key dike routes in the Project to improve the safety of the dike system in Quang Ninh province in the period of 2025-2030, with a vision to 2050, including the routes Binh Duong - Dong Mai, Van Dong, An Bien, Tan Viet - Duc Chinh, Song Nguyen, with a total length of more than 18km, with a total estimated investment of over 400 billion VND. Along with that, the locality proposed to consider building a new dike route in Ben Trieu and Dong Tan areas to enhance flood prevention capacity, protect residents and riverside production areas. When these items are implemented, the capacity to prevent natural disasters, prevent tides and protect people's lives of Dong Trieu Ward will be significantly improved, contributing to ensuring safety in the downstream area and promoting sustainable socio-economic development.

Quang Ninh currently has over 341km of dykes, including level III, IV, V dykes along with a system of culverts, embankments and auxiliary works. Along with Mao Khe ward, many other dyke routes in localities in the province will be prioritized in the Project to improve the safety of the dyke system to adapt to climate change in the period 2025-2030, with a vision to 2050.

The dyke system in Quang Ninh province plays a particularly important role in the prevention and control of natural disasters, storms and floods, response to climate change, and protection of the lives and property of the State and people. In the current context, Quang Ninh is not only a key province in the mining industry but also strongly develops in the processing industry, services, tourism and urban areas. Therefore, the functions and tasks of the dyke system have expanded, in addition to protecting residents and agricultural production as before, it must also protect industrial parks, tourist areas, services, large urban areas and key traffic routes, directly contributing to stabilizing and promoting socio-economic development.

To ensure the safety of the dike system in the context of increasingly complex climate change, Quang Ninh province is urgently completing the Project to improve the safety of the dike system, adapt to climate change in the period 2025-2030, with a vision to 2050. The goal of the project is to improve the efficiency of management, operation and development of the dike system in a synchronous, modern direction, proactively responding to extreme natural disasters; protect the safety of residents, property, and socio-economic development space; at the same time exploit the multi-purpose of the dike system, both preventing floods and storms, serving traffic and protecting the ecological environment, contributing to the sustainable development of coastal and riverside areas until 2050. The total expected investment for the entire project is more than 6,000 billion VND.

The Nguyen River dike (Dong Trieu ward) is degrading and needs investment and repair.

In the 2026-2030 period, the project aims to completely handle 100% of the dike sections and vulnerable locations that are not yet safe, and at the same time complete the investment and synchronous upgrading of river dikes and estuary dikes to meet current flood and storm protection standards, ensuring the safety of large urban areas, economic zones, industrial parks and concentrated residential areas. Along with that, the province will focus on protecting and maintaining the stability of the existing mangrove forest area in front of sea dikes and estuary dikes to enhance natural protection capabilities.

In the 2031-2050 period, Quang Ninh will continue to upgrade coastal dykes, ensuring that 100% of the dyke system meets new safety standards and is able to withstand extreme natural disaster scenarios. At the same time, the province will expand the area of ​​mangrove forests, forming sustainable "green shields", contributing to reducing investment and maintenance costs and improving long-term disaster prevention effectiveness.
