Mangrove ecosystems represent natural capital capable of producing a wide range of goods and services for coastal environments and communities and society as a whole. There are different methods of estimating the economic value of mangrove ecosystems which may serve to demonstrate the significant potential of wealth increase with the conservation of natural mangrove capital. Economists generally decompose the total economic value of ecosystems into direct use, indirect use and non-use values. Coastal Protection- Mangroves stabilize coastlines and preserve coral reefs, as well as filter water. This review gives a comprehensive overview of adaptations of mangrove root system to the adverse environmental conditions and summarizes the ecological importance of mangrove root to the ecosystem. Results The role of mangroves as C sinks needs to be evaluated for a wide range of biogeographic regions and forest conditions. In terms of habitat use, the mangrove support to commercial, recreational and subsistence fisheries is well documented (see review in Rönnbäck, 1999 ). endstream endobj startxref Watch Queue Queue Mangroves need to be understood for the valuable socio-economic and ecological resource they are, and conserved and managed sustainably.
