Context

Recurring extreme rainfall events in India and the lack of lessons learned from them.

Details

• Since the Uttarakhand disaster in 2013, India has experienced major extreme rainfall events every year.
• Scientists have been warning about the increase in intensity and frequency of heavy rainfall events.
• These events have resulted in large-scale flooding, destruction, and loss of lives in various parts of the country.

Recurring Extreme Rainfall Events

• Major extreme rainfall events have occurred in multiple cities and regions, including Kashmir, Chennai, Bengaluru, Pune, Mumbai, Gurgaon, Kerala, Assam, and Bihar.
• The trend aligns with scientific predictions of more intense and concentrated rainfall within shorter periods of time.

Causes of Disasters

• Extreme weather events have become inevitable, but the resulting disasters are not solely due to natural causes.
• Official incompetence, neglect, callousness, and greed aggravate the impact of these events.
• Improper construction, blocked water channels, population growth in vulnerable areas, and encroachment on floodplains contribute to the severity of the disasters.

Specific Examples

• Bengaluru experiences annual flooding not due to unusual rainfall, but primarily because natural water channels have been blocked by irregular construction.
• Srinagar faced unprecedented flooding in 2014 due to heavy rainfall and population settlements in low-lying areas along the Jhelum river.
• Kerala's destruction in 2018 resulted from settlements and tourist infrastructure on floodplains.
• Mumbai's recurring floods are attributed to broken or clogged drainage systems.
• The Uttarakhand disaster was worsened by unregulated construction and poorly planned infrastructure.

Lack of Learning and Opportunities

• Each extreme rainfall event in the past decade has served as a warning and offered opportunities for learning.
• However, very few lessons have been learned, and there is still a lack of action and preparedness.
• India is currently in the process of building infrastructure, presenting an opportunity to design resilient systems that can withstand the expected impacts of climate change.
