Why AI may be our best defence against disasters

From heatwaves and floods to cyclones and glacial risks, disasters are becoming routine. Artificial Intelligence offers India a chance to shift from reacting after losses occur to preventing them before they happen.

“The real promise of AI is not faster response after disasters, but smarter decisions before losses occur.”

Disasters no longer arrive as sudden shocks. In India today, they feel more like a slow, relentless tide. Heatwaves stretch for weeks, floods return year after year to the same neighbourhoods, cyclones intensify over warming seas, and mountain hazards threaten communities far downstream. Climate change has transformed disasters from rare interruptions into a permanent development challenge.

The real question facing policymakers is no longer whether disasters can be predicted. It is whether losses can be prevented. This is where Artificial Intelligence (AI) is beginning to change the rules of disaster risk reduction—not as a futuristic add-on, but as a practical decision-making tool that can help governments act earlier, smarter, and more decisively, before hazards turn into humanitarian crises.

For decades, disaster management has focused on response: rushing relief after rivers overflow or temperatures cross dangerous limits. But climate risks today are continuous and interconnected. Extreme heat affects health systems, power demand, and labor productivity simultaneously. Floods disrupt transport, food supply, and urban services at once. Cyclones damage infrastructure, livelihoods, and ecosystems in a single blow. Managing such complexity increasingly exceeds human capacity alone. AI helps bridge that gap.

At the foundation of AI-enabled disaster management lies image intelligence. Satellites, drones, and sensor networks already generate enormous volumes of data every day. AI allows this information to be analyzed continuously to detect early warning signs—urban heat islands forming in dense settlements, floodplains being encroached upon, coastlines retreating, or subtle land deformation in Himalayan valleys. These are not disasters yet, but precursors. Acting at this stage offers the highest return on investment in prevention.

Several countries have demonstrated how powerful this approach can be. The Netherlands, for instance, uses AI-driven flood risk models that combine satellite imagery, river behavior, land use, and infrastructure data to guide spatial planning decisions. Flood management is embedded into everyday governance rather than treated as an emergency function. As climate extremes intensify, losses remain relatively contained because risk is managed upstream. Japan offers another instructive example. AI-powered systems integrate seismic, meteorological, and infrastructure data to support real-time decisions during earthquakes, typhoons, and floods. What makes Japan stand out is not technology alone, but governance discipline. AI outputs are linked to clear thresholds for action, automated alerts, and routine public drills. The result is trust—citizens know warnings are credible and act on them.

Another quiet but significant transformation is underway through Large Language Models, or LLMs. One of India’s biggest challenges in disaster governance is not lack of data, but information overload. Forecasts, advisories, guidelines, and standard operating procedures often exist in silos across agencies and levels of government. During emergencies, this complexity can slow decisions rather than speed them up.

LLMs can act as cognitive assistants—synthesizing complex climate and weather information and translating it into clear, actionable advisories. In parts of Southeast Asia, AI-based platforms already convert weather forecasts into farmer-specific guidance delivered in local languages via mobile phones. Instead of abstract warnings, users receive advice on when to plant, harvest, or protect assets.
The most transformative applications of AI, however, go beyond prediction to prescription. Agent-based models and optimization systems simulate how people, infrastructure, markets, and institutions behave under stress. They allow policymakers to explore “what-if” scenarios before disasters strike and expose trade-offs that would otherwise remain hidden.

India stands at a critical moment. The country has strong scientific institutions, advanced satellite capabilities, and a rapidly expanding digital public infrastructure. AI is already used for cyclone tracking, flood mapping, and drought monitoring. The next step is integration—embedding AI across the full disaster risk cycle, from prevention and preparedness to recovery and long-term adaptation.

Consider extreme heat, now among India’s deadliest hazards. AI can identify neighborhood-level heat hotspots, estimate health risks, and translate warnings into targeted advisories for outdoor workers, schools, and hospitals. In floods, AI can combine rainfall forecasts, river data, and socio-economic information to trigger anticipatory actions before waters rise.

Yet AI itself is not the endpoint. The next wave lies beyond AI—towards systems that combine machine intelligence with human judgment, ethics, and governance. Hybrid intelligence systems will support decision-makers while accounting for uncertainty, equity, and local context.

The real challenge, therefore, is not technological. It is institutional and political. Are we willing to invest more in prevention than in post-disaster relief? Can AI be embedded into planning, finance, and governance, rather than confined to emergency response?
In a warming world, disasters will test not just our forecasting ability, but our willingness to act early. AI offers India a rare opportunity to shift from reacting to disasters to staying ahead of them. Whether it becomes our best defense will depend not on algorithms alone, but on the choices we make now.
