Mangroves failed to protect coastal villages in ‘04 tsunami – INQ7.net “The World Conservation Union, also known as IUCN, and other nongovernmental organizations earlier reported that mangroves saved lives in Sri Lanka and India — a finding they said could motivate hard-hit communities across Asia to consider replanting mangroves. A quarter of mangroves have been destroyed in tsunami-impacted countries since the 1980s due to development and the rapid growth of shrimp and fish farms. But Baird, of James Cook University in Queensland, Australia, and his co-authors argued that governments would be better off putting their resources into an early warning system and evacuation plans. They also called for many coastal communities to be moved to higher ground.
