摘要

Land, a finite resource, is shrinking in extent and deteriorating in qualify as a result of expanding urbanization, industrialization, varied civic uses and mismanagement of water resource. The current gap between demand and supply of land, fuel, fodder and timber is likely to worsen in near future as a consequence of continuing degradation of land and reduced per capital land availability. Irrigation in a particular situation may degrade the land, if not scheduled and planned properly as per the requirement of crop and soil. Suitability evaluation of land for irrigation is a systematic appraisal of land and their designations by categories or classes on the basis of physical and chemical characteristics (Resler 1979). Land suitability provides a rational basis to analyse various soil, nurtrients and land parameters to arrive at optimum solution to various problems of natural resources. It includes land capability classification, land lrrigability assessment, soil suitability for crops, suitability to plantation / trees / aquaculture etc. Remote Sensing has shown great potential in Land suitability model mapping and monitoring due to its advantages over traditional procedures in terms of cost and time effectiveness in the availability of information over larger areas.. Hence, it is proposed to use remote sensing data for the mapping of natural resources. Nevertheless, the surface reflectance spectra over a wide range of objects and conditions should be identified and interpreted into meaningful outputs prior to decision-making and applications. Satellite Remote sensing images, such as IRS- LISS, PAN and W1FS are proposed to use. GIS (Geographic Information System) has become an important tool because it enables to integrate the complex decisions to be taken under milti-variant situations of the resource base and their dynamics. Survey of literature reveals that GIS techniques have been employed for development of land suitability model for Irrigation Management.
