The coastal settlements in Bangladesh experienced recurring tropical cyclones and tidal surges in recent history because of geographical influences and global climate change. Despite improved evacuation management and adequate cyclone shelters patronized by donors, lately resulting in a reduced mortality rate, the property and economic losses were still substantial due to vulnerability of the settlements. As the short-term adaptative approaches such as migrating to the closest cyclone shelters have failed to sustain resilience, comprehensive and inclusive mitigation planning should be implemented to achieve more resilience in the long term. The research aimed to revise the conventional culturally-void concept and propose a prolonged solution by planning a self-sustained model of the cyclone-resilient village for the south-western coastal communities of Bangladesh. Initially, it searched for the identification and analysis of socio-cultural, economic, and environmental challenges in sustaining community resilience and later synthesizing architectural interventions to achieve self-sustenance. The synthesis focused on reducing the vulnerability of the coastal communities by enhancing their preparedness, resistance, and recovery from the prolonged impacts of coastal disasters through designing structurally and environmentally resilient homesteads, defensive landscape plans, and socioeconomic-communal development. The ultimate proposal offers more flexibility in selecting homesteads according to suitable materials, affordability, and profession.
This study focused on spatial analysis to identify the changes inadaptability over the last five decades. The features influencing adaptabilitywere selected from the reference study. An appropriate method was used toanalyse these features through spatial analysis. Six distinctive typologiesof rural houses were selected from six regions. Unlike the traditionalhouses, the contemporary houses in the same area reflected a differentcharacter. Urban houses built since the early and mid-20th century werecompared with contemporary houses. After analysing the openness,generality, flexibility, depth, typicality, construction technique, involvementof end-users, and the feedback from the inhabitants, the study identified asignificant decrease in contemporary houses' adaptability. Spatial analysiswas used to quantify the different features and comparison betweentraditional and contemporary houses. Though the adaptability had beenreduced over time, the latest houses started to achieve better flexibility insome features due to government policy and implementation of statutorybuilding regulations. Further recommendations were provided to enhancethe residential architecture's adaptability in future. The study samples wereselected from different regions of Bangladesh. Still, the result and policyrecommendations can be helpful for other countries, especially with highpopulation density and a developing economy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
