Tsunami-Blocking Mangroves Lure Carbon Investors: Southeast Asia Bloomberg Replanted mangrove trees in Southeast Asia are getting credit for protecting against deadly tsunamis and typhoons such as Haiyan in the Philippines and cutting greenhouse...
Mangrove regeneration in Northern Samar, about 100 miles (160 kilometers) north of the worst-hit Philippine city of Tacloban, helped minimize damage from the Nov. 8 storm, according to the Trowel Development Foundation, which oversaw the plantings. On Indonesia’s Sumatra island, where a 2004 tsunami killed 170,000 residents, companies including Danone and Credit Agricole SA (ACA) have put up about $4 million in exchange for tradable carbon offsets tied to the reforestation.
Mangroves have twisted webs of roots above ground that absorb carbon dioxide linked to climate change and help protect coasts from tidal surges such as the one that killed at least 3,900 people when Typhoon Haiyan swamped the Philippines this month. The storm, one of the strongest to make landfall, has gripped UN climate talks in Warsaw this week, with a Philippine delegate tearfully calling for action to slow climate change.
“Had we not protected the mangrove trees against illegal cutting and had we not planted the areas surrounding the fish farms with native mangrove species, the super typhoon would have destroyed everything that the poor fisherfolks established,” Leonardo Rosario, a development consultant on the Northern Samar project, said by e-mail on Nov. 19.
