What are the common flooding issues in Indian cities?

1. Outdated Drainage Systems: Many cities, including Delhi and Mumbai, have old drainage systems that cannot handle heavy rainfall. For example, parts of Delhi were submerged multiple times this year.
2. Poor Urban Planning: Urban planning often ignores local hydrology, worsening flood impacts. Cities like Pune and Mumbai have struggled with ineffective planning.
3. Ineffective Civic Response: Civic agencies mainly focus on relief and rescue rather than proactive measures. In Pune, electrocution deaths occurred due to waterlogged areas.
4. Climate Change: Climate change increases the intensity of extreme weather events. Cities like Mumbai and Pune experienced nearly 45% more rainfall than usual. This exacerbates flooding and damage in these cities.

What is being done to address the flooding issue?

1. Climate Action Plans: Mumbai and Pune have plans for climate adaptation. Mumbai’s plan includes collaboration with industry, academia, and civil society, but implementation is slow.
2. Inconsistent Drain Improvement: Stormwater drain projects in cities like Mumbai and Pune have progressed unevenly, indicating a need for more consistent efforts.
3. Advanced Warning Systems: Buenos Aires uses 30,000 sensors in stormwater drains to issue early flood warnings, demonstrating a proactive approach that Indian cities could adopt.

What should Indian cities focus on to improve flood management?

1. Indian cities need better stormwater drain systems and effective climate adaptation measures. Projects for improving drains have been inconsistent.
2. To reduce flood damage, cities should adopt both natural and technological solutions, starting with essential infrastructure improvements.
