Due to certain aquaculture and agriculture practices as well as other factors, since the 1950s, Vietnam lost more than 80% of its mangrove forests (shrubs or trees that grow on coastal shorelines). Mangrove forests are useful in decreasing storm surge levels, reducing the height of waves and stabilizing sediments. Motivated by the vulnerability of Vietnam to storm surges and flooding, the Government of Vietnam implemented mangrove forest restoration activities. These activities resulted in concrete positive impacts including: expansion of new mangroves forests by 18,000 hectares; reduction in a storm surge wave height from 4 to 0.5 meters along a particular stretch of sea dike; and reduction in the cost of dike maintenance by US$ 7.3 million per year. Key actions and good practices profiled in this case study are highlighted below.
