Mangrove vegetation has a very complex function for human life now and in the future. Therefore protecting mangrove areas by preventing damage and reforesting in mangrove areas that have improved degradation must continue. The purpose of this study is to identify changes in mangrove areas for five years, as well as their impact. A literature review of previous research studies used to assess the impact of a decrease in the mangrove area, along with conservation strategies. The results showed that the degradation of mangroves for land conversion can result in decreased carbon stocks in sediments, changes in abiotic conditions in the media, a decrease in the number of fish catches, the occurrence of abrasion and a decrease infauna of the Mollusca group association. Integrated coastal management should pay attention to the sectoral dimension, dimensions of science and ecological dimensions.
