21 mar 2017 · This chapter examines the value of salty coastal ecosystems, focusing especially on salt marshes, mangroves and drylands, and the current state of threatened halophytes.
Despite their importance, saltmarsh areas are declining around the world, having lost between 25% and 50% of their global historical coverage (Crooks et al. 2011, Duarte et al. 2008).Vast areas have been lost through conversion to agriculture, urban and industrial land, while remaining saltmarshes face many other current and potential threats (Gedan et al. 2009): land claim for industry, port ...
Saltmarshes are extremely valuable but often overlooked ecosystems, contributing to livelihoods locally and globally through the associated ecosystem services they provide, including fish production, carbon storage and coastal protection.

30 lis 2022 · Globally, salt marshes occur across all continents, except Antarctica, in low-energy tidal environments. About 40% of the mapped salt marsh extent is found in North America and about 25%...
Between 2005 and 2009, North America experienced 61 the largest 2net loss of any region in a single epoch (282.6 km ). Here we found that watersheds 62 impacted by higher category hurricanes lost more salt marsh. This highlights the climate 63 dependance of these systems and expected increases in losses from climate change due to
7 gru 2022 · In a recent research paper, scientists described the first consistent global accounting of salt marsh locations and changes. The work also allowed them to start estimating the amount of carbon dioxide — a greenhouse gas — emitted into the atmosphere as marshland is degraded or lost.
