Appraising Spatio-Temporal Shifting of Urban Growth Center of Pimpri-Chinchwad Industrialized City, India Using Shannon Entropy Method

Abstract

Uncontrolled urban development of Pimpri Chinchwad area was assessed to understand shifting of urban growth center and its controlling factors during last forty years. Out of forty, initial 20 years span (1973 to 1993) is compared to subsequent 20 years (1993 to 2013). The secondary data i.e. topographic maps (year 1970 and 2009) and satellite image MSS, LISS III (year 1973 and 1993) and LISS IV image (year 2013) were used for preparation of land use land cover maps. Furthermore, Shannon entropy computed by built-up land class, was showing the entropy 0.81, 0.92 and 0.97 for year 1973, 1993 and 2013 respectively, hence the steady growth during past forty years. However, growth centers of urban development shifts from automobile industries at Pimpri (central part) to information technology (IT) industries towards Hinjewadi (western part) area. This shift was determined from the demographic alteration in study area. To understand demographic alteration, the spatial results were verified through ground truth survey reveals population growth is in the form of vertical growth such as increase in multi storey buildings instead of single storey housing. This study highlights the shifting of urban growth centers in developing countries such as India from automobile to IT industries. The shifting of growth center was resulted into impact on existing public services (drinking water, sanitation, waste management, roads, hospitals etc.). In conclusion, present study warrants the attentions towards shifting of urban growth center from such rapidly growing industrial city of the developing countries while deciding future urban planning.
