The study by Barbier et al. (2013) examines the value of coastal wetlands in protecting southeast Louisiana from hurricane storm surges. Using hydrodynamic simulations and economic valuation, the authors demonstrate that the presence of coastal marshes and their vegetation significantly reduces storm surge levels, thereby minimizing property damage. The analysis, conducted along a transect in the Caernarvon Basin, shows that a 0.1 increase in wetland continuity per meter reduces property damages by $99-$133, and a 0.001 increase in vegetation roughness decreases damages by $24-$43. These reductions are equivalent to saving 3 to 5 and 1 to 2 properties per storm, respectively. The findings highlight the economic benefits of restoring and maintaining wetlands as a natural defense against hurricane damage, emphasizing the importance of wetland conservation and restoration efforts.The study by Barbier et al.
