KeralaKerala StateLocal and indigenous knowledge system is rich in its biodiversity and valuable ecosystem services. This gives vital support to human well-being and sustainable development. However, it is susceptible to impacts of climate changeClimate change like sea-level riseSea level rise, cyclones, erosion, flooding, tidal attacks, storm surges, etc. The sandy beaches, sand dunes, and mangrove forestsMangrove forests which are critical morphological features that provide natural coastal protection, are being destroyed for economic gain. The dynamic coastline of Kerala is constantly changing and is getting reshaped by ocean currents, storms, etc., that are linked to climate changeClimate change. Coastal hazardsCoastal hazard mitigation are often unpredictable. The marine fishing community is the most vulnerable. Three coastal marine fishing villages of KeralaKerala, which were affected by the December 2004 Indian Ocean tsunamiTsunami, have been chosen for the study. The elderly fishers possess Local and Indigenous KnowledgeIndigenous knowledge System (LIKS) through which they cope with the adverse situation. These are often Nature-based SolutionsNature based solutions (NbS), that leverage nature and the power of healthy ecosystems to protect people and safeguard stable biodiverse future. This paper will bring to light the current indigenous practices and Nature-based SolutionsNature based solutions prevalent for the prevention and mitigationMitigation of Climate changeClimate change induced coastal hazardCoastal hazard mitigations. Participatory methods are used for rediscovery of Nature-based SolutionsNature based solutions (NbS). This is based on a series of focus group discussions, key informant interviews, etc., among the fishing communitiesCommunities that had helped to understand their resilienceResilience to coastal hazardsHazards.
