Mangroves reduce coastal incursion, seawater ingress, sea-level rise, cyclonic storms and tsunamis. Natural ecosystems such as mangroves, sand dunes, coral reefs, submarine rocks and seagrass came to be referred to as “bio shields” in a post-tsunami world.

Pichavaram, Cuddalore: On December 26, 2004, a tsunami in the Indian Ocean wreaked havoc along the coasts of several countries of South and Southeast Asia. However, for a small tribe called Irula living in Pichavaram, Cuddalore district, Tamil Nadu, the tsunami would prove to be a blessing in disguise.

The Irulas are a semi-nomadic tribal community of hunter-gatherers who lived a marginalised life eking out a living by hunting snakes and selling the skins. But after the tsunami, the government finally included them on the List of Scheduled Tribes and provided them with the necessary certificates. This allowed them access to welfare schemes and granted them much needed food and livelihood security.

When the disastrous waves receded, ravaged coastal communities were left picking up the pieces of their lives. But in Pichavaram, the story was dramatically different. A post-calamity analysis undertaken by the scientists of the MS Swaminathan Research Foundation (MSSRF) revealed that the Pichavaram mangrove forest protected the coastal villages from the tsunami.
