Indian landslide tragedy demands a rethink of hazard mapping in a changing climate
Briefly

The catastrophic landslides in Wayanad serve as a stark reminder of the urgent need for improvement in landslide hazard mapping practices. Despite previous warnings, the devastation affected hundreds, resulting in significant loss of life and infrastructure. This tragedy underscores the necessity for more effective predictive models and community preparedness to mitigate such risks in the future.
Current landslide hazard mapping methods in Kerala have proven inadequate in predicting such disasters. The Wayanad incident illustrates the shortcomings in data collection and analysis, pointing to a need for more rigorous scientific approaches to understand the terrain and climatic variables influencing landslide occurrences. Without advancement in these areas, similar tragedies are likely to recur, leading to further loss of life.
The recent tragedy in Kerala not only highlights the immediate human cost but emphasizes the ongoing challenges faced by scientists and policymakers in addressing landslide risks. The authors advocate for a collaborative effort among geologists, hydrologists, and climate scientists to refine mapping techniques and enhance emergency response strategies that can save lives as extreme weather events become more prevalent.
In light of the Wayanad landslides, it is imperative that stakeholders shift their focus towards proactive measures, encompassing improved hazard assessment and community engagement strategies, instead of purely reactive responses after disasters occur. Comprehensive planning should integrate local knowledge and scientific expertise to build resilience against future hazards.
