Environmental movements in India and geospatial technology and environmental management

1. Environmental Movements in India India also has a historical tradition of social awareness Educating the masses about maintaining cleanliness and hygiene - Gadge Maharaj . The Bhishnoi community of Rajasthan which lived a very eco-friendly lifestyle. Indian civilisation being one of the ancient civilisations scientific rational and environment friendly culture Since ancient times there has been healthy relationship between the people and their surroundings. These strong ties between society and environment have from time to time given rise to movements

2. Major Environmental Movements in India Chipko Movement Appiko Movement Narmada Bachao Andolan Save Western Ghats movement

3. Geospatial Technology Geospatial technology refers to the techniques and instruments used for collecting, mapping and analysing geographical data of the earth’s surface and human societies. Geospatial technology have been developed through Aerial Photography, Remote Sensing, Geographical Information System (GIS), Global Positioning System (GPS), etc. This technology is effectively used in resource planning and management, waste management, traffic control, disaster management and various other areas related to environmental planning and management.

4. Applications of Geospatial technology in Environmental Management – Remote Sensing Remote sensing is the most preferred source for collecting environmental data of large areas for its use in GIS. RS include not only data collection process but also data analysis The advantage of remote sensing is the bird’s eye view or synoptic view it provides, so that environmental data of large areas can be captured instantaneously

5. Applications of Geospatial technology in Environmental Management – Remote Sensing Aerial photography and satellite remote sensing are two major types of remote sensing. Satellite remote sensing not only helps to obtain spatial information of large geographical area but also provide coverage to repetitive information of the same location. Satellite RS applications help in real time monitoring of various natural and anthropogenic phenomenon.

6. Role of Remote Sensing in Environmental Management Real time monitoring of natural disasters like forest fire, tsunami, earthquakes, cyclones, avalanches etc. Land use and land cover mapping for proper land use planning. Resource mapping Identification of mineral sites Water resource monitoring

7. Role of Geographical Information System in Environmental Management A Geographic Information System is a computer based tool for mapping and analysing features, events on Earth. GIS is another important technological capacity which can be of immense help in developing environmental measures to tackle environmental issues. Information such as land cover, species diversity, distribution, water resources etc. can be integrated to make models for investigation. We can analyse the changes in the amount of forest cover in an area, glaciers, carbon level, pollution can be assessed etc.

8. Role of Global Positioning System in Environmental Management Global Positioning System has helped us in fixing our position on the surface of the Earth. GPS is based on a constellation of 24 high altitude satellites. Accurate tracking of environmental disasters such as fire and oil spills can be tracked down easily with the help of GPS.
