Strengthen dikes and embankments to avoid being caught off guard by natural disasters.

Faced with the increasingly evident impacts of climate change and extreme natural disasters, Quang Ninh province is urgently finalizing the Project to Enhance the Safety of the Dike System in Adaptation to Climate Change for the period 2025-2030, with a vision to 2050. The project aims to comprehensively invest in the province's dike system, linked 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 section of the Ha Nam dike running through Lien Hoa ward has been solidly constructed, ensuring safety.

Dong Trieu Ward is one of the localities in the province with a large and complex dike system, with 7 dike lines totaling nearly 20km in length, playing a crucial role in protecting the population, agricultural production, and riverside infrastructure. However, due to the impact of extreme weather, storms, and years of use, many dike lines have deteriorated, posing a potential safety risk, especially during the rainy season. Some dike sections have low crest elevations, steep slopes, weak foundations, and sandy soil, failing to meet technical standards and easily leading to seepage, overflow, and landslides when river levels rise. Typical examples include the Tan Viet - Duc Chinh, An Bien, and Binh Duong - Dong Mai dikes, many of which have not been upgraded, with storm resistance only reaching levels 6 to 9, posing a significant risk during 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 inhabitants, Dong Trieu ward is developing strongly in the direction of industry, services, and urbanization, while also being a high-tech agricultural area. In this context, ensuring the safety of the dike system is not only a task to protect people's lives but also a fundamental element for sustainable socio -economic development.

Mr. Le Van Hung, Vice Chairman of the People's Committee of Dong Trieu Ward, said: Given this situation, Dong Trieu Ward has proactively prepared a report and proposed that the province include critical dike sections in the Project to Enhance the Safety of the Dike System in Quang Ninh Province for the period 2025-2030, with a vision to 2050. These include the Binh Duong - Dong Mai, Van Dong, An Bien, Tan Viet - Duc Chinh, and Song Nguyen sections, with a total length of over 18km and an estimated total investment of over 400 billion VND. In addition, the locality has requested consideration for the construction of a new dike embankment road in the Ben Trieu and Dong Tan areas to enhance flood control capabilities and protect residents and production areas along the river. When these projects are implemented, the capacity for disaster prevention, tidal control, and protecting the livelihoods of the people in 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 dike system in Quang Ninh province plays a particularly important role in disaster prevention and control, flood mitigation, climate change adaptation, and protecting the lives and property of the State and the people. In the current context, Quang Ninh is not only a key province for mining but also experiencing strong development in processing industries, services, tourism, and urbanization. Therefore, the functions and tasks of the dike system have expanded. Beyond protecting the population and agricultural production as before, it must now protect industrial zones, tourist and service areas, major cities, and vital transportation routes, directly contributing to the stability and promotion of socio-economic development.

To ensure the safety of the dike system in the context of increasingly complex climate change, Quang Ninh province is urgently finalizing the Project to Enhance the Safety of the Dike System and Adapt to Climate Change for the period 2025-2030, with a vision to 2050. The project aims to improve the efficiency of management, operation, and development of the dike system in a synchronized, modern manner, proactively responding to extreme natural disasters; protecting the safety of residents, property, and socio-economic development space; and simultaneously exploiting the multi-purpose use of the dike system, serving both flood and storm prevention, transportation, and environmental protection, contributing to sustainable development of coastal and riverine areas by 2050. The total estimated investment for the entire project is over 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.
