The phenomenal population explosion has led competitive and unplanned exploitation of the planet earth which has resulted irrepairable damage to the environment. Such improper exploitation of natural resources and the interaction of human beings with earth’s ecosystems has not only depleted the natural resources but also triggered off the natural morphodynamic processes of the earth which in turn are causing natural disasters and chains of environmental problems such as landslides, land subsidence, soil erosion, reservoir siltation, flooding, water logging, coastal erosion, etc. On the other hand, domestic, industrial and other wastes, whether these are of low or medium level wastes, are causing environmental pollution and have become a perennial problem for the mankind. However, while the human-induced environmental problems warrant detailed studies, the environmental pollution due to waste disposals can be overcome by selecting suitable sites through careful understanding of the lithospheric and hydrospheric conditions of the planet earth. The art of remote sensing is an excellent tool in mapping such lithospheric and hydrospheric parameters and the GIS is a proven tool in storing, retrieving, analysing and amalgamating all such parameters to select suitable sites for such waste disposals. The present paper brings out a certain newer package of information on how suitable sites can be identified for disposing wastes using remote sensing and GIS technologies.
The Newer Concepts The sites which attain the credentials for waste disposals are normally the
