There’s the high tech approach to minimizing tsunami deaths — a global alert system that tries to predict tsunamis — and then there’s the low tech approach — mangrove swamps. This should not be a surprise – wetlands are very effective at combatting flooding, for example, far more so than levees and dams. And while it is anthropomorphic to say that “the wetlands are nature’s method of protecting people,” it is useful to observe that wetlands have preserved many lands and try to cultivate them for that purpose.

Mr. Selvum says that 172 families were saved from the tsunami in the fishing village of Thirunal Thoppu in India’s Tamil Nadu state only because the mangroves are thriving and dense there. He also mentions three other Tamil Nadu villages where damage had been minimized by the aquatic trees. “Every village has more than 100 families, so just think of the number of lives saved,” he says. “Even though the mechanical impact of a tsunami is enormous, and is bound to destroy the first line of mangroves, the water suddenly slows down as it moves farther in,” Selvum says.
