Mekong Delta localities plant trees, build natural embankments to prevent erosion

Vietnam Plus

More people in the Mekong Delta are planting trees and building embankments made of natural materials to prevent erosion along rivers and canals.

The delta, which has a dense river and canal network, has faced increasing erosion along rivers and canals in recent years because of human activity and climate change.

In Hau Giang Province, the Irrigation Sub-department built three natural embankments with a total length of 380 metres on a pilot basis to prevent erosion in Phung Hiep District and Nga Bay Town in 2017.

The natural embankments are made by filling eroded areas with soil and setting up a barrier made of cajuput trunks or bamboo between the embankments and water.

Cajuput and crabapple mangrove trees are planted inside the barriers so that their roots prevent soil erosion. Permeable fabric or fine nets are installed outside the barrier to hold the soil.

At the embankments, water hyacinths are grown along banks to reduce the strength of waves hitting the banks.
