1. The Context: A Shift in Strategy
India is hosting the India-AI Impact Summit 2026, focusing on using Artificial Intelligence (AI) to save lives and the planet.
- The Shift: India is moving from a “Relief-centric” approach (reacting after a disaster) to a “Prediction-centric” approach (predicting it before it happens) using AI.
2. AI in Disaster Prediction (Early Warning)
- Cyclones: The India Meteorological Department (IMD) uses the “Advanced Dvorak Technique” to estimate cyclone intensity from satellite images. New AI models can now predict cyclone paths up to 96 hours in advance.
- Floods & Landslides:
- BrahmaSATARK: A dedicated AI tool that provides flood forecasts specifically for the Brahmaputra Basin.
- Landslide Monitoring: Low-cost sensors in Himachal Pradesh now give alerts 3 hours before a landslide occurs.
3. Last-Mile Connectivity: Reaching the Village
Technology is useless if it doesn’t reach the people. India is democratizing climate data:
- Bharat Forecasting System (BharatFS): Launched in 2025, this indigenous model provides hyper-local weather forecasts (at 6 km resolution) directly to Gram Panchayats.
- MausamGPT: An AI-chatbot designed to advise farmers on weather patterns in simple, local languages.
4. Institutional Innovation
- IIT Bombay (SpADANet): Developed a tool to assess post-cyclone damage using aerial images, helping authorities plan relief faster.
- IIT Kharagpur: Created an AI model to map Arsenic contamination in groundwater in the Ganga delta, ensuring safe drinking water.
UPSC Value Box
| Concept / Tool | Relevance for Prelims |
| Sendai Framework | An international agreement (2015-2030) to reduce disaster risk. India’s AI initiatives directly fulfill Target G: Increasing access to Multi-Hazard Early Warning Systems. |
| Advanced Dvorak Technique | A method used by meteorologists to determine the intensity of a Tropical Cyclone based on satellite cloud patterns (it looks at the “eye” and “banding” of the storm). |
| BrahmaSATARK | A specific flood forecasting model developed for the Brahmaputra river basin, which is highly prone to annual flooding. |
With reference to disaster management technologies recently seen in the news, the term “Advanced Dvorak Technique” is primarily associated with:
- Predicting the occurrence of high-magnitude earthquakes using seismic gaps.
- Estimating the intensity of tropical cyclones using satellite imagery.
- Mapping groundwater arsenic contamination in the Ganga delta.
- Monitoring forest fires using machine vision cameras.
