Lack of long-term plans to mitigate rain-inducted calamities worrying for Kerala
CM blames IMD for delay in relaying weather forecast. However, experts point out that IMD’s 125-year rainfall dataset, covering 110 weather stations across Kerala from 1901 to 2025, has shed enough light on the State’s most vulnerable regions during monsoon and the government need not wait for weather alerts before initiating preparedness measures

Context
Recent rain-induced calamities in Kerala, including severe flooding and landslides, have sparked a debate between the state government and the () regarding the timeliness of weather warnings. However, experts point out that the core issue is the state's lack of a comprehensive, long-term disaster mitigation strategy, particularly concerning land-use planning in highly vulnerable zones along the Western Ghats.
UPSC Perspectives
Geographical
UPSC frequently tests the relationship between physical geography and disaster vulnerability. Kerala's geography, particularly the steep slopes of the Western Ghats, makes it highly susceptible to landslides and flash floods during extreme rainfall events. This vulnerability is exacerbated when the offshore trough (a low-pressure area parallel to the coast) extends along India's west coast during the monsoon, bringing intense precipitation. Weather scientists have utilized historical data, machine learning, and Geographic Information System () techniques to map this vulnerability, creating colour-coded zones. The recent disasters in Idukki, Pathanamthitta, and Wayanad occurred in 'red zones'—areas with a 125-year history of repeated extreme rainfall. This highlights that while acute weather events act as triggers, the underlying geographical predisposition is constant and predictable.
Disaster Management & Governance
For GS Paper 3, disaster management is a critical topic. The article underscores a shift from reactive to proactive disaster management, a core principle of the . Relying solely on real-time alerts from the () for mass evacuations is a flawed, short-term strategy. The faces structural challenges in implementing long-term mitigation. Effective disaster management requires integrating vulnerability mapping (like the GIS maps mentioned) into development planning. The lack of a comprehensive long-term plan indicates a failure in governance and policy implementation, where political or social resistance often trumps scientific necessity.
Environmental & Ecological
The environmental lens focuses on the human factors exacerbating natural vulnerabilities. The article identifies the absence of effective land-use planning as a critical aggravating factor. In densely populated states like Kerala, unregulated construction, deforestation, and inappropriate agricultural practices in ecologically sensitive areas (like the Western Ghats) increase the risk of disasters. Furthermore, the reluctance to undertake necessary ecological maintenance, such as removing accumulated silt and sand from rivers (often due to local resistance or complex regulations), reduces the carrying capacity of water bodies, leading to faster and more severe flooding. This ties into the broader debate on sustainable development and implementing the recommendations of the or on the Western Ghats.
