Being a source of natural renewable resources, Mangroves significantly play a role in the local economy and coastal livelihood, eventually contributing to the national economy and regional environmental balance. Unfortunately, a downward shifting for the area has been observed from 16.1 million ha (1990) to 15.6 million ha (2010), and the removal is faster than other ecosystems.....
