The recent torrential rainfall in Bengaluru, India's technology hub, has exposed the city's vulnerabilities and highlighted the urgent need for better urban planning. The city, often referred to as "India's Silicon Valley," experienced its heaviest rainfall in nearly 30 years, leading to widespread flooding, building collapses, and significant disruptions for its 1.4 crore residents. The heavy rains, which lasted for several days, raised concerns about the city's ability to cope with extreme weather events, especially as climate change brings more frequent and intense rainfall.
The impact of the rains was felt across the city, with schools forced to close and many employees working from home. The heavy rains caused the collapse of a building under construction in Babusapalya, resulting in the tragic deaths of five workers. Residents shared their experiences of flooding, power outages, and the difficulties of commuting during the downpour. One resident described water entering her house through the kitchen chimney, highlighting the widespread flooding that affected many homes.
The issue at hand is not merely a matter of extreme weather; it is a result of the city's rapid growth and unplanned development. Experts point to the lack of vision in urban planning, particularly the destruction of wetlands and the conversion of green spaces into concrete areas. This has significantly reduced the city's capacity to absorb rainwater, leading to widespread flooding. The Indian Institute of Science has revealed that Bengaluru has lost 88% of its green cover over the past four decades, while concrete areas have increased elevenfold. This shift has made over 85% of the city susceptible to flooding.
The heavy rains serve as a stark reminder of the consequences of unsustainable development. The city's rapid economic growth has come at a high environmental cost, leaving it vulnerable to climate change impacts. The need for a holistic approach to urban planning, prioritizing environmental sustainability, is paramount. This involves investing in robust drainage systems, preserving green spaces, and promoting sustainable building practices. The city needs to learn from this recent experience and take proactive steps to mitigate the risks posed by future extreme weather events.
