People living in Sundarban islands of India have been experiencing increasing impacts of saline water floods. The existing livelihood stress becomes higher due to frequent disasters that forced local people to migrate in search of income activities. All disasters are local and “first responders” have an important role to manage the disaster. The problems of state-dependent disaster reduction mechanisms are not becoming adequate to meet the local needs. Therefore, affected people work together to save lives and properties by utilizing local resources. These resources are based on salt water, soil, and collective activities. Utilization of local resources helps them to reduce floods and generate multiple alternative livelihood options. The main objectives of the chapter are to understand how natural resource-based strategies reduce disaster and in what ways these strategies enhance resilience of people. A qualitative study in villages of the Indian Sundarban has found that the flood-affected villagers try to reduce their dependence on external supports and chalk out new strategies to live with the risk. These strategies become unique for managing the disaster in the frequently flood-affected hamlets. As there are inadequacies of the local government to address all the needs of people, local communities take efforts to form groups to find local resource dependent alternative livelihood, repairing or building house, building temporary shelters, distribution of relief materials, ensuring safe drinking water, stopping school dropout, and also taking initiatives to manage disasters. Local initiatives are often supported by the local government and work collaboratively. The local resource-based collaborative efforts strengthen the relationship among the local government and communities and build the confidence among them to enhance resilience and cope with disasters.
