The Vietnam Disaster and Dyke Management Authority under the Ministry of Agriculture and Rural Development, in collaboration with Son La province's Department of Agriculture and Rural Development and the Japan International Cooperation Agency (JICA) Vietnam Office, held a groundbreaking ceremony for the construction of the first experimental Sabo dam in Vietnam at Pieng village, Nam Pam commune, Muong La district, Vietnam Agriculture newspaper reported.

The Sabo dam pilot project in Ban Peng, Nam Pam commune, Son La province is sponsored by JICA with a total capital of VND 8.2 billion (USD 328.000), with an open concrete structure, 51m wide, 9m high, expected to be completed in September 2024.

The Sabo Dam is one of the most effective engineering solutions for mitigating the impacts of erosion and flash floods. These dams are typically constructed on the upper reaches of rivers with steep slopes and high flow velocities. Additionally, Sabo dams help retain sediment, and floating debris, and prevent damage in downstream areas.

The construction of the experimental Sabo dam is one of the most important activities within the framework of the Technical Cooperation Project for Strengthening the capacity to cope with and minimize damages caused by flash floods and landslides in the northern mountainous region of Vietnam.

The project has been implemented across 14 northern mountainous provinces of Vietnam since 2022 through a partnership between the Vietnam Disaster and Dyke Management Authority and JICA.

The construction of the experimental Sabo dam in Son La province is expected to serve as a reference for the Government of Vietnam to establish technical standards for Sabo dam design, before initiating the construction of other Sabo dams in high-risk areas.

Furthermore, the construction of this dam will reinforce the National Planning for Disaster Prevention and Water Resources from 2021 to 2030, with a vision towards 2050.
