Coastal Projects Threaten Ho Chi Minh City Mangroves

Mangroves protect coastlines by reducing flood and storm risks, stabilizing sediment, supporting fisheries and storing carbon, but their benefits depend on local conditions and intact water flows. In Vietnam, plans for a new seaside city, port and connecting infrastructure near Ho Chi Minh City could disrupt the Can Gio forest, a key natural buffer for a highly flood-prone metropolis, even as officials promote the projects as economic and logistics investments. In Pakistan, mangrove restoration is also being developed as a carbon-credit business, but the marketable carbon value may not reflect the forest’s direct importance to nearby communities, and intermediaries can absorb an undisclosed share of project revenue. In India’s arid Kutch region, a new field manual offers locally tailored guidance for restoration amid high salinity, scarce freshwater and erosion. Research and conservation guidance suggest mangroves can complement built coastal defenses, but effective protection and restoration require planning around forest width, tides, sediment and community needs.
