<p><i>Haor</i> region is highly vulnerable to a multitude of climate-driven natural hazards, impacting the lives and livelihoods of millions of people. The impacts are disproportionately felt as the marginalized people suffer the most. While the people have taken adaptive measures at both individual and community levels in response to these extreme climate events, these efforts remain insufficient to address the increasing frequency and intensity of such events. There is a pressing need for a long-term, well-guided adaptation plan to ensure resilient livelihoods for millions of <i>haor</i> dwellers. Our study aims to assess the livelihood vulnerabilities in the face of climate change-driven natural hazards and to develop long-term adaptation strategies to promote resilient livelihoods for the people living in <i>haor</i> region. To achieve this objective, we employed a mixed-method approach which involves both quantitative and qualitative techniques. We conducted household surveys, key informant interviews, and focus group discussions to assess the impacts of natural hazards, document existing adaptation strategies, and understand the needs and priorities of local communities. An integrated participatory approach involved multiple stakeholders including local government, community representatives, experts and implementing agencies to identify and evaluate the adaptation options and sequence them over short, medium and long term. The results highlight key adaptation options that can help decision-makers to implement well-guided actions toward climate-adapted futures and mainstream <i>haor</i> development plans, addressing a long-standing gap in the region's development trajectory.</p>
