The southernmost province of Ca Mau has announced a state of emergency following the erosion of 2.7 km (1.67 miles) of coastal embankment.
The declaration came Wednesday with five dike sections along its western coast in Tran Van Thoi and U Minh districts on the verge of collapsing due to the impact of waves.
According to local authorities, protective forests in those sections have either disappeared or shrunk.
The Department of Agriculture and Rural Development is standing by with vehicles and personnel if required for rescue missions and evacuating and relocating people out of dangerously eroded areas.
Ca Mau has a total coastline of over 250 km.
