The scorching sun beating down on Bengaluru is a reality that residents are increasingly having to grapple with. What was once considered pleasant weather throughout the year is now giving way to sweltering heatwaves that pose a significant threat to public health, livelihoods, and even basic necessities like water.
Recognising the urgency of this issue, a research team from the Ashoka Trust for Research in Ecology and the Environment (ATREE) has embarked on a crucial initiative titled ‘Understanding Systemic Impacts of Heat Stress in Bengaluru’. This project sheds light on the multifaceted ways that heatwaves impact the city; aiming to inform effective response strategies.
The project focuses on Marappanapalya ward, a microcosm of Bengaluru that encompasses diverse demographics; from industrial areas and commercial spaces to low-income settlements and affluent high-rises. By employing satellite data, the researchers were able to establish a clear link between sparse green cover and areas experiencing the most extreme temperatures.
Their investigation takes it further than just observational research. The team has identified various systems – health, water, energy, and waste – that are profoundly affected by heatwaves. They have also spoken to a cross-section of residents in order to gaugehow people perceive and respond to the heat.
The current approach to heatwaves, as the researchers point out, is often reactive and fails to consider the ground realities. Heat advisories issued by authorities tend to place the onus on individuals to take action, overlooking the interconnectedness of various systems within the city. For instance, a security guard's ability to adjust work timings hinges on the willingness of their workplace to adapt as well. This domino effect necessitates a holistic approach that considers the collective impact on all sectors.
Another challenge identified by the researchers is the way heatwaves are understood at the local level. The criteria used by the India Meteorological Department (IMD) to define a heatwave may not translate accurately to the lived experience in urban areas. Factors like humidity and the ‘real feel’ temperature are not taken into account.
The ATREE project aims to bridge this gap by bringing their findings to the attention of policymakers. They advocate for a systemic approach that acknowledges the complex interplay between heatwaves and various urban systems.
One immediate outcome of the project is the ‘Climate Vulnerability Walk’ – a community engagement initiative designed to raise awareness. Participants are guided through the ward, visiting key locations to discuss how heat impacts specific systems and stakeholders. This fosters a collaborative space where residents can share their vulnerabilities and brainstorm solutions.
The team is planning to expand their outreach through various means, including educational toolkits for children and exploring alternate avenues for advocacy.
The scorching heat gripping Bengaluru is a stark reminder of the changing climate and this project aptly demonstrates how proactive research and community engagement can pave the way for a more climate resilient city.
