Theme Name : Natural Resource & their Conservation
“Uses or Remote Sensing and G.I.S. (Geographical Information System) for Conservation and Preservation of Soil and Water Resources – Loktak a Case Study”
Introduction: Soil erosion is one form of soil degradation along with
soil compaction, low organic matter, los s of soil structure, poor internal
process on all land. The agents of soil erosion are water and wind the
information on soil erosion in needed for variety of purpose like planning reclamation programmes, rational and land use planning, for bringing additional areas into cultivation and also to improve the productivity levels.
Remote Sensing: The Electromagnetic Radiation (EMR) emitted by an object on earth’s surface, atmosphere and ocean are detected and classified by means of aerial sensors without any physical contact with the object. This phenomenon of acquiring information about an object is called remote sensing.
Geographical Information System: Geographical Information System (GIS) is a system designed to capture, store, manipulate, analyze, manage and present all types of geographical data.
Application of Remote Sensing and GIS in Soil Erosion: The conventional method of soil survey is time consuming and expensive Remote sensing technology is the new technology for studying natural resources. It is a synoptic view of the terrain, features, responsive covering of the same area at regular intervals of time, collecting data in visible through near infrared, thermal to microwave reasons and a men ability of data of GIS for quick analysis.
Conclusion: Thus, in order to preserve the ecosystem of a place, it is necessary to conserve the soil and water resources of the place. The nature of soil erosion of a particular area can be clearly studies from the datas obtained by Remote Sensing and GIS. Thus the datas obtained may be analyzed for the nature of erosion, type of erosion and the erosion may be checked through paper management of land.
