Another Monsoon, Another Mess
On Friday, as the monsoon asserted its strength over Kolkata, steady showers quickly led to waterlogged streets and traffic snarls. At Netaji Subhas Chandra Bose International Airport, the scene was predictably tense. Airlines like SpiceJet began issuing
travel advisories, warning passengers of potential delays due to the bad weather. This has become a familiar ritual for Indian flyers during the monsoon. It's not just Kolkata; in recent days, heavy rains have caused significant disruptions at major hubs like Delhi and Mumbai, with airlines urging passengers to constantly check their flight status.
A Pattern of Disruption Across India
The issue extends far beyond just one city or one season. This year's monsoon has already seen intense rainfall disrupt operations in Mumbai, leading to hundreds of delays and dozens of cancellations. Similarly, Delhi's Indira Gandhi International Airport has faced its own share of weather-related chaos, with flights being diverted due to heavy downpours and low visibility. These are not isolated incidents. In recent years, airports in Bengaluru, Chennai, and Ahmedabad have all suffered from severe waterlogging and operational shutdowns due to extreme weather, from torrential rains to cyclones. A lightning strike on a stationary aircraft in Kolkata just last month further highlighted the diverse weather challenges airports now face.
When Modern Ambition Meets Aging Infrastructure
India is now the world's third-largest domestic aviation market and is undergoing a massive airport expansion and modernization drive. However, this rapid growth is running headfirst into two critical challenges: aging infrastructure and the escalating impacts of climate change. Many of our airports, even recently upgraded ones, were not designed to handle the frequency and intensity of the weather events we see today. Engineering assumptions based on historical rainfall data are becoming increasingly unreliable as climate change delivers once-in-a-century storms with alarming regularity. The result is runways and terminals flooding, not because of a single cloudburst, but because the underlying infrastructure is not equipped for the new climate reality.
More Than Just an Inconvenience
Repeated flight disruptions are more than just a headache for passengers. They create a massive ripple effect across the economy. For a nation aspiring to be a global business and tourism hub, unreliable airport operations are a significant liability. The delays and cancellations cost airlines millions, disrupt crucial supply chains that rely on air freight, and damage India's reputation as an efficient place to do business. As India’s airports operate at or beyond their intended capacity, there is little room to absorb these kinds of shocks, leading to a domino effect of delays across the entire national network.
The Urgent Need for Climate-Proofing
The solution is not simple. It requires a fundamental rethink of how we plan and build critical infrastructure. Investing in better drainage systems is a start, but true resilience involves a multi-pronged approach. This includes upgrading navigation and landing systems, such as advanced Instrument Landing Systems (ILS), to allow for safer operations in poor visibility. More importantly, future airport design must incorporate forward-looking climate projections, not just historical data. It means building for the weather of tomorrow, not the weather of yesterday. While some airports have improved their resilience, the recurring disruptions show that the pace of adaptation is not keeping up with the pace of climate change.
