Ecosystem based Disaster Risk reduction is the sustainable, green method to minimize cyclone damages at tropical coasts. As a part of a climate change resilience project initiated in 2012, 102 hectare of multispecies mangrove plantation was established at eastern corner of Indian Sundarbans. The AMPHAN supercyclone, have caused immeasurable destruction in the region, between 16-21st May, 2020. This research brings forward the field observations on effectiveness of community managed mangrove plantation in ameliorating disaster impacts. Study revealed that mangrove bio-shield minimized property damage during the cyclone by reducing flooding through earthen embankment stabilization and managing the wind speed, direction.
