According to the 2024 World Risk Report, India ranks third in disaster frequencies among Asian countries. One such disaster was the 2004 Indian Ocean TsunamiTsunami, which left deep scars on the coastal communitiesCoastal communities of KeralaKerala, severely impacting not only fishing but also agricultural livelihoods due to saltwater intrusion into coastal aquifers. This intrusion caused farmlands to become swampy and salty, rendering them unsuitable for irrigation. The ripple effects of climate changeClimate change on livelihoods have sparked a growing interest in sustainability reportingSustainability reporting (SR) for agricultural risk managementAgricultural risk management. This paper aims to understand the impacts of the 2004 tsunami2004 tsunami on the farming sector of the AlappadAlappad Panchayat, a coastal communityCoastal communities in Kerala, and the remedial measures undertaken through government initiatives. It underscores the necessity for SR. The data was collected through a literature review, including journal articles, government reports, and informal discussions with various community stakeholders. Findings indicate that farmers are aware of the sector’s risks, which include crop loss, low yields, soil degradation, and revenue loss. However, there is a lack of standardized reporting guidelines for risk assessment, timelines for resource allocation for mitigationMitigation, and clear communication pathways between smallholder farmersSmallholder farmers, financial institutions, and other supporting agencies, which can help mitigate livelihood losses during disasters. The study concludes with several recommendations, including (1) promoting SRSustainability reporting during regular periods through training and capacity building, (2) identifying actions to ensure financial sustainability during disasters, and (3) encouraging awareness of nature-based solutionsNature based solutions (NbS) for long-term coastal farmland resilienceResilience and sustainability.
