The National Disaster Management Authority (NDMA)'s 'Sachet' mobile application and the Sachet National Disaster Alert Portal are delivering real-time disaster warnings to farmers and fishermen across Gujarat's coastal regions, significantly reducing the risk to lives and livelihoods during extreme weather events. Deployed actively in the state, the app has emerged as a critical early-warning tool amid a monsoon season that sent approximately 70 crore messages through various warning systems in Ahmedabad alone.

How the Sachet App Works

The Sachet app uses Common Alerting Protocol (CAP) and geo-fencing technology to push location-specific alerts about cyclones, heavy rainfall, lightning, floods, and heatwaves directly to users' mobile phones. Unlike traditional mass communication channels such as TV and radio — which involve significant time lags — the app delivers warnings in real time, allowing communities to act before conditions deteriorate.

Alerts are simultaneously transmitted to state government agencies, local administration, panchayats, and village-level bodies, enabling faster coordination of relief and rescue operations.

Voices from the Field

Ambubhai Patel, a farmer from Valsad, described the app as transformative. 'If a farmer's crop is ready for harvest, they can move it to a safe location. The Sachet app provides crucial information to the public,' he said. Patel noted that the app alerts farmers about impending storms and rainfall in time for them to return safely from their fields.

Fisherman Bhagubhai Tandel echoed the sentiment, calling the app 'excellent for the fishing community' and noting that it provides timely information whenever there is a likelihood of rain — a critical advantage for those venturing into open waters.

What Officials Said

Ashok Kumar Das, Director of the Ahmedabad Meteorological Department, confirmed that weather information and updates are disseminated through the app, ensuring communities receive timely advisories. Relief Director S.C. Savaliya noted that approximately 70 crore messages were sent via various warning systems in Ahmedabad during this year's monsoon season, underscoring the scale of the platform's reach.

Broader Impact and What's Next

The Sachet app is now serving as what officials describe as a 'digital safety shield' for thousands of residents vulnerable to weather extremes. This comes amid growing recognition that last-mile alert delivery — reaching individual farmers and fishermen rather than just district administrations — is the weakest link in India's disaster preparedness chain. The Gujarat deployment offers a replicable model for other coastal and flood-prone states. Wider rollout and integration with additional meteorological data sources could further sharpen the app's predictive utility.
