Describe the role of the Indian Remote Sensing (IRS) satellite programme. How do these satellites assist in natural resource management?

In short

The IRS programme, run by ISRO with NRSC as the nodal data agency, supplies repeated geospatial data for planning the use of land, water, soil, forests and coasts. Satellites like Resourcesat map land use, groundwater, erosion and disaster damage, guiding drought mitigation in Rayalaseema and coastal management in Andhra Pradesh.

Introduction
The Indian Remote Sensing (IRS) satellite programme, launched in the 1980s, is central to India’s space-based natural resource management, providing critical geospatial data for sustainable development and climate adaptation. ISRO’s Sriharikota launch facility in Andhra Pradesh plays a strategic role in deploying these satellites.
Institutional Framework and Capacity
•

ISRO and NRSC Leadership

ISRO runs the IRS programme with the National Remote Sensing Centre (NRSC) handling data acquisition and distribution under the Remote Sensing Data Policy 2011, balancing security with accessibility.

Implementation in Resource Management
•

Land and Crop Monitoring

IRS satellites like Resourcesat-1 and 2A provide multispectral data for land use and crop mapping, supporting agricultural planning in Andhra Pradesh’s horticulture and chilli cultivation belts.

•

Water Resource Management

Satellite data aid surface and groundwater inventory, watershed management, and irrigation planning, supporting the Jal Shakti Abhiyan1 in Andhra Pradesh for drought mitigation.

•

Environmental and Soil Health

IRS data detect land degradation and soil salinity, aiding sustainable land management in Rayalaseema’s drought-prone areas.

•

Disaster and Coastal Management

IRS satellites assist early warning and coastal zone management along Andhra Pradesh’s 974 km coastline, protecting fisheries and marine ecosystems.

Way Forward
•

Enhance Data Resolution

Upgrading sensors will improve precision for localized applications in Andhra Pradesh’s agro-climatic zones.

•

Capacity Building

Training state agencies will empower local use of IRS data in Andhra Pradesh’s rural and coastal districts.

•

Integrate with Schemes

Combining IRS data with schemes like the Soil Health Card and Pradhan Mantri Fasal Bima Yojana will improve resource allocation.

Conclusion
The IRS programme is vital for effective natural resource management, supporting sustainable development and resilience across India.
