[font size=5]The best defense against catastrophic storms: Mother Nature, say Stanford researchers[/font]
[font size=4]Stanford researchers say that natural habitats such as dunes and reefs are the best protection against storms and rising sea levels along the U.S. coastline.[/font]
[font size=3]Extreme weather, sea level rise and degraded coastal systems are placing people and property at greater risk along the coast. Natural habitats such as dunes and reefs are critical to protecting millions of U.S. residents and billions of dollars in property from coastal storms, according to a new study by scientists with the
Natural Capital Project at the Stanford Woods Institute for the Environment.
The study, "
Coastal habitats shield people and property from sea-level rise and storms," published July 14 in the journal Nature Climate Change, offers the first comprehensive map of the entire U.S. coastline that shows where and how much protection communities get from natural habitats such as sand dunes, coral reefs, sea grasses and mangroves. The likelihood and magnitude of losses can be reduced by intact ecosystems near vulnerable coastal communities.
One map shows predicted exposure of the United States coastline and coastal population to sea level rise and storms in the year 2100. An interactive
map can be zoomed in on for the West, Gulf or East coasts; Hawaii or Alaska; or the continental United States.
"The natural environment plays a key role in protecting our nation's coasts," said study lead author Katie Arkema, a Woods postdoctoral scholar. "If we lose these defenses, we will either have to have massive investments in engineered defenses or risk greater damage to millions of people and billions in property."
