Flooding has emerged as one of the most destructive climate-induced challenges for Assam and West Bengal, two Indian states already grappling with diverse vulnerabilities. This study examines the evolving nature of flood damage between 1961 and 2020. We investigate the compounding factors of rapid population growth, aggressive urbanisation, and escalating asset exposure on flood damages. Based on a quantitative approach, we find an alarming trend in flood-related damages, with Assam experiencing a compound annual growth rate of 6% and West Bengal at 6.6%, reflecting the accelerating threat to livelihoods, infrastructure, and agriculture. As floods intensify, these states have seen damage expand from rural agricultural lands to densely populated urban areas, amplifying the financial toll on public utilities, housing, and economic assets. The paper highlights the inadequacy of current flood management systems, focusing on how insufficient infrastructure and encroachment into floodplains have increasing disaster impacts. Moreover, it evaluates the potential of innovative strategies like climate risk insurance, contextualised through establishing the Loss and Damage fund, to offer critical risk-transfer mechanisms for both states. This research underscores the need for a paradigm shift from reactive disaster management to proactive, localised resilience-building measures. It calls for immediate and tailored interventions—rooted in community participation, effective land-use planning, and robust infrastructure development—that align with the specific vulnerabilities of each state. By addressing both socio-economic and environmental drivers of vulnerability, Assam and West Bengal can mitigate future losses and build a more sustainable, resilient future in the face of rising flood risks.
