Bangladesh faces significant climate change vulnerability due to its low-lying topography, deltaic location on the Bay of Bengal, and dense population. This study investigates the nation's vulnerability to climate change impacts, focusing on challenges such as reduced freshwater availability, surface drainage congestion, sea level rise, increased flooding, and coastal storms. Examining the roles of governmental organizations and non-governmental organizations in addressing these challenges, the research analyzes their current efforts, identifies shortcomings, and proposes improvements. Emphasizing the importance of effective collaboration, the study explores how resource and expertise sharing can enhance coping mechanisms and facilitate sustainable development. Employing a mixed-methods approach, the research utilizes documentation, content analysis, and field data collected from fifteen GOs and NGOs actively engaged in climate change mitigation and adaptation initiatives. Findings reveal that while numerous organizations are working towards addressing climate change challenges, a lack of coordination hinders their overall effectiveness. The study advocates for strategic partnerships, emphasizing the sharing of experiences, ideas, and resources, leveraging international and experiential knowledge, and fostering community involvement as crucial elements in building resilience and achieving sustainable development goals in the face of a changing climate.
