Abstract

The gradual migration of local labor for jobs abroad has made a remarkable impact on the land use in the local region. The large scale migration was chiefly the outcome of unemployment in the local region as a result of the shutdown of the rayon industry which was the only source of income to the local village community. Two phenomena were observed parallel since 2001. First, the migration pattern of labor force in the study area, and second, the changes in land use pattern. In this background of the problem it is interesting to observe the land use changes through remote sensing during different time periods.

Highlights

  • The rayon industry is popularly characterized as causing distress on the health of people and environment

  • The primary and immediate impact of the shutdown was observed on outmigration of people in search of jobs and the secondary impact was realized on the land use change

  • This study analyzes the impact caused from the shutdown of rayon industry on land use change

Summary

Introduction

The rayon industry is popularly characterized as causing distress on the health of people and environment. A large number of rayon industries worldwide have shut down as a result of the peoples opposition upon their continuation. In India the Greenpeace group has backed for the closure of the Mavoor rayon factory, and has demanded an adequate compensation for the damage done to the environment and residents around this region. The Gwalior Rayon’s started production of pulp and fiber for textile in 1960 which caused a rapid change in the life style of native population followed by a tremendous regional development. After the opening of the rayon industry the land use structure of the region has underwent enormous change causing great impact on the natural vegetation, and agricultural lands. This study analyzes the impact caused from the shutdown of rayon industry on land use change. The application of remote sensing and image processing technologies are able to answer questions related to the spatial land use patterns and precisely estimate the extent of land in various land uses and their distribution and change over time
