Implementation of nature-based solutions (NbS) into conservation practices of urban built heritages in Bangladesh: challenges, possibilities, and prospects.

The preservation of rich cultural and architectural heritages in Bangladesh, alongside its diverse natural environment, is increasingly prioritized through conservation efforts. Integration of Nature-based Solutions (NbS) into these practices, leveraging existing green elements and natural landscapes for cost-effective conservation processes. This research explores the potential of Nature-based Solutions (NbS) within the heritage structures of Bangladesh, identifying feasible areas for implementation and examining the benefits beyond regular conservation process. Nature-based Solutions (NbS) not only aids in preserving heritage but also enhances sustainability in water management, promotes health, sequesters carbon, boosts biodiversity, and improves acoustic comfort. By harnessing nature's resilience, these solutions offer sustainable responses to challenges posed by climate change, urbanization, and industrialization, which also threaten heritage sites. Integrating Nature-based Solutions (NbS) requires effective implementation strategies, policy support, and community engagement to ensure success. In this research, specific study- based method was followed and implemented in some heritage sites to generate suggestive conclusions in case of implementation of Nature-based Solutions (NbS). This study aims to analyze the feasibility and suggest practical approaches for implementing Nature-based solutions (NbS) in the conservation of cultural heritages of Bangladesh, emphasizing resilience, socio-economic benefits, and the preservation of natural and built environments.
