Model Answer
Introduction
Remote sensing and Geographic Information Systems (GIS) are vital tools in managing natural resources in India. These technologies allow for the collection, analysis, and management of spatial data, enabling informed decision-making in the sustainable use and conservation of resources.
Role of Remote Sensing and GIS in Managing Natural Resources
Remote sensing provides accurate satellite imagery to map land cover types, enabling the monitoring of land use changes and identifying encroachments. This data helps in planning for sustainable land management and conservation.
Remote sensing helps monitor forest cover, assess deforestation, and detect illegal activities like logging. It also assists in reforestation efforts by providing up-to-date information on forest health and density.
Remote sensing assists in monitoring water availability, quality, and stress areas, crucial for water resource management. It aids in identifying regions prone to droughts or water scarcity.
Remote sensing provides real-time data for monitoring crop health, yield estimation, and detecting areas affected by pests, diseases, or drought. It aids farmers in making informed decisions about agricultural practices.
Remote sensing and GIS support disaster management by providing timely, accurate information on natural disasters like floods, cyclones, and earthquakes. This helps in real-time assessment and decision-making during disaster response.
Conclusion
Remote sensing and GIS play an essential role in the management of natural resources in India. They support informed decision-making, enhance resource conservation, and contribute to sustainable development and disaster resilience.
