THE STUDY OF CHANGES IN THE LAND USE AND LAND COVER AROUND SIDHI IN SON RIVER VALLEY USING IRS I-A (LISS II)SATELLITE IMAGERY

摘要

Land is one of the basic and viable resources for human existence. It provides man with the basic necessities of life. With the development of civilization the needs of human society have multiplied and diversified. Accordingly the various uses to which the land is put have also diversified. Land is a finite resource, with the explosive growth and spread of population it is progressively becoming a scarce resource. Consequently it has become inevitable to have a sound land use management for the sustained use of this increasingly scarce resource. Land use information forms an important part of decision making at state level. The present study is an attempt to study the changes in the land-use pattern between 1966-67 and 1991 in the region around Son River Valley. The study is based on composite approach encompassing the process of data acquisition, data and satellite image interpretation, and data representation done systematically through the techniques of cartography and remote sensing. Significant changes in the land-use pattern in the study area have been observed in the past 3 decades in the study area. Forest cover has reduced by approximately 7 percent, scrub land has increased approximately by 7 percent, agricultural area has expanded by 4 percent from 32.38 percent in 1966 to 36.02 percent in 1991
