Assessing the impact of it parks on surrounding villages using GIS: A case study of Hinjewadi and Talwade IT Park Pune

The expansion of urban areas is common in metropolitan cities on India. Pune also has experienced rapid growth in the fringe areas of the city. This is mainly on account of the development of the Information Technology (IT) Parks. These IT Parks have been established in different parts of Pune city. They include Hinjewadi, Kharadi, Talwade and others like the IT parks in Magarpatta area. This area has been undergoing rapid changes in land use in the last few years. The changes in the land use that have occurred in areas surrounding Hinjewadi and Talwade IT parks during the last two decades have been studied by analyzing the LANDSAT images of different time periods. The satellite images of the 1992, 2001, 2011 and 2015 were analyzed to detect the temporal changes in the land use and land cover. This paper attempts to study the changes in land use/land cover which has taken place in these villages in the last two decades. Such a study can be done effectively with the help of remote sensing and GIS techniques. The tertiary sector has experienced a rapid growth especially during the last decade near the IT Park.

The land use of study area has been analysed using the ground truth applied to the satellite images for these years. Using the digital image processing techniques, the satellite images were then classified and land use/land cover maps were derived, some of which include agricultural land, water bodies, barren land, fallow land and settlements. There has been a major change in the area under cultivation due to the establishment of the IT Park. There is also a phenomenal change in the percentage of area under settlements and barren land. These changes will have an impact on the socio-economic landscape of the region.
