As a researcher deeply engaged with climate challenges in South Asia, I often find myself examining the tension between rapid urbanization and environmental vulnerability. Our recently published study in Discover Sustainability, titled "Urban Household Adaptation to Extreme Heatwaves: Health Impacts, Socio-Economic Disparities, and Sustainable Strategies in Rajshahi," emerges from this intersection.
This research was motivated by the urgent need to address the increasing frequency and intensity of heatwaves in Rajshahi, a city facing unique socio-economic and climatic challenges. The Urban Heat Island (UHI) effect exacerbates the risks associated with extreme temperatures, impacting public health, productivity, and overall quality of life. Our mixed-methods approach aimed to unravel these challenges, focusing on adaptation strategies and highlighting systemic disparities.
The key findings were significant. Low-income households, with limited access to cooling resources, predominantly rely on passive methods, which are often insufficient to mitigate health risks. Gender disparities were notably pronounced, as women reported higher levels of anxiety and less access to adaptation measures due to socio-cultural norms. Similarly, outdoor laborers faced acute vulnerabilities due to their occupational exposure.
A pivotal moment during our research occurred when we interacted with residents in Rajshahi’s low-income neighborhoods. Their resilience in the face of adversity, juxtaposed with their vulnerability, underscored the importance of targeted interventions. It became evident that education plays a crucial role in fostering awareness and adaptive behavior, while economic barriers continue to pose a significant challenge.
Below is a conceptual representation of the principal adaptation strategies identified in the study, categorized into behavioral, resource-based, and structural adaptations, highlighting their socio-economic influences.
Our study also explored sustainable solutions, advocating for green infrastructure, improved urban planning, and community-centric adaptation strategies. The goal is not only to inform policy but also to inspire actionable change that prioritizes equity and inclusivity.
I hope this paper will serve as a valuable resource for policymakers, urban planners, and advocates of climate resilience. It is a call to action to address the cascading impacts of climate change on vulnerable urban populations and a reminder of our collective responsibility to build resilient communities.
