Anavaran Portal (Deforestation Alert System)

Context

The Forest Survey of India (FSI) has recently discontinued the Anavaran Deforestation Alert System, a digital platform that monitored forest cover loss using satellite data.

Q1. What is the Anavaran Portal?

1. The Anavaran Portal was a technology-based monitoring system designed to detect and report forest cover loss across India which was launched in January 2024 by FSI.
2. Key features
   1. Used satellite imagery and machine learning to identify forest cover changes.
   2. Generated location-specific alerts every 15 days.
   3. Enabled State forest departments to conduct targeted ground inspections.
3. The platform aimed to strengthen near real-time monitoring of deforestation.

Q2. What technologies were used in the Anavaran Alert System?

The system relied on satellite imagery and cloud-based geospatial analysis tools.

1. Google Earth Engine (GEE) The platform operated on GEE which enabled processing and analysis of large volumes of satellite data.
2. Sentinel-2 Satellite: Provided high-resolution optical imagery. Used to identify changes in vegetation and forest cover.
3. Sentinel-1 Synthetic Aperture Radar (SAR): Radar-based imaging capable of penetrating clouds and rain. Allowed forest monitoring during cloudy or monsoon conditions.

These technologies enabled continuous and large-scale monitoring of forests.

Q3. What is the Forest Survey of India (FSI)?

1. It is the primary national institution responsible for assessing forest resources in the country.
2. Establishment: 1 June 1981. It succeeded the Preinvestment Survey of Forest Resources.
3. Background of PISFR: Initiated in 1965 by the Government of India. Implemented with support from the Food and Agriculture Organization and the United Nations Development Programme.

Q4. What are the key functions of FSI?

1. Monitoring and assessment of forest and tree resources.
2. Conducting forest-related research and training programs.
3. Supporting policy planning for forest conservation.
4. Providing data and analysis for sustainable forest management.

Q5. What is the State of Forest Report (SFR)?

1. The State of Forest Report is the flagship publication of the Forest Survey of India which provides a comprehensive assessment of forest and tree cover across India and is published every two years since 1987.
2. The report relies on remote sensing satellite imagery and field-based National Forest Inventory (NFI) data.
3. The SFR serves as an important tool for tracking forest trends and guiding forest policy.

Conclusion

The Anavaran Portal demonstrated the potential of satellite technology, machine learning, and geospatial analysis in monitoring forest resources. Although the system has been discontinued, it highlighted the importance of digital tools and remote sensing for improving transparency, early detection of deforestation, and evidence-based forest governance in India.
