Cyclone Aila struck West Bengal in May 2009, devastating the Sundarbans region and displacing over 3 million people. In the Mathurapur II block of South 24 Parganas district, several villages were worst hit by the high winds and 4-meter tidal surge. Society for Integrated Development and Social Action (SIDSA) provided emergency relief to the affected villages, including safe drinking water, dry food distributions, medical camps serving 4000 people, and mosquito nets to prevent disease outbreaks. Over the next two months, SIDSA's humanitarian response aimed to meet immediate needs and support long-term recovery of the devastated communities.
