Introduction:
The coastal areas of Bangladesh face serious problems due to climate change. They are often hit by cyclones, tidal surges, and saltwater intrusion.(Eckstein et al., 2021). Traditional infrastructure often does not provide lasting support in vulnerable areas. This study looks at how bioinspired architecture and nature-based solutions (NBS) can help create climate-friendly and sustainable designs for coastal Bangladesh. It focuses on utilising natural concepts to enhance building design and functionality. (Pawlyn, 2011; Raymond et al., 2017).
Methods:
A multi-method approach was used, combining qualitative field research, participatory interviews with coastal residents, and ecological mapping. This provided insights into community perspectives and ecological dynamics. A seven-stage co-benefit assessment framework was applied to evaluate how environmental health supports social resilience and economic vitality in coastal areas. (Raymond et al., 2017) guided the evaluation of architectural strategies in terms of environmental impact, community resilience, and policy integration. Biomimetic inspiration was drawn from natural systems such as mangrove root networks, forest edge layering, and leaf morphology, which were abstracted into functional design elements (Benyus, 1997; Badarnah, 2017).
Results:
The study reveals that bamboo stilt housing, when thoughtfully modified with bioinspired structural principles, demonstrates a substantial enhancement in flood resilience. By incorporating layered defensive landscaping that mimics the natural stratification found in forests, these structures create an effective buffer against the destructive forces of high winds while concurrently fostering biodiversity. This innovative approach not only protects the housing from potential flood damage but also supports a rich ecosystem, allowing various plant and animal species to thrive in harmony with human habitation.(Sohaana & Rahman, 2021). These strategies also improve microclimate control and reduce energy use. Participatory processes enhanced social cohesion and contextual relevance.
Conclusion:
Bioinspired architectural and landscaping strategies offer a scalable and regenerative solution to climate risks in Bangladesh's coastal belt. By integrating ecological patterns into architectural systems, these approaches transform the built environment into a co-evolving partner with nature, reinforcing resilience, sustainability, and human well-being.
