越南湄公河下游三角洲充满活力的海岸线受到气候变化的影响，特别是风暴和洪水强度和频率的增加以及海平面上升的威胁。最有效的海岸保护系统由串联排列的不同要素组成，例如长满红树林的天然洪泛区和坚固的堤线。然而，海岸带自然资源的不可持续利用和开发正在威胁红树林林带的保护功能。在严重侵蚀破坏红树林地带的地点，只有在波浪能量被物理屏障减少后，才可能恢复洪泛平原和红树林恢复。这可以通过竹栅栏来实现，它减少了侵蚀并刺激了沉积。被侵蚀的洪泛区的恢复为被破坏的红树林的恢复创造了先决条件。红树林管理是该地区海岸保护战略的重要组成部分。
The dynamic coastlines in the Lower Mekong Delta of Vietnam are threatened by the impacts of climate change, particularly by the increased intensity and frequency of storms and floods, as well as by rising sea levels. The most effective coastal protection systems consist of different elements arranged in series, for instance natural floodplains vegetated with mangroves and a sound dyke line. However, the unsustainable use of natural resources and development in the coastal zone are threatening the protection function of the mangrove forest belt. In sites where severe erosion has destroyed the mangrove belt, restoration of floodplains and mangrove rehabilitation is only possible after the wave energy has been reduced by physical barriers. This can be achieved with bamboo fences, which reduce erosion and stimulate sedimentation. Restoration of the eroded floodplains creates the pre-conditions for rehabilitation of the destroyed mangrove forest. Mangrove management is an important element of an area costal protection strategy.
