Assessing the Impact of Transport Corridors on Peripheral Urbanization: A GIS-Based Study of Land Use/Land Cover Changes in Warangal, India

Author(s) Dr. N. Srinivasu
Country India
Abstract The transport corridors also play a huge role in the peripheral urbanization of the developing cities, forming unique linear development zones as opposed to those that are not affected by the corridors. The paper uses spatial analysis of GIS and multi-temporal satellite imagery (2000-2020) to measure the connection between the proximity of transport corridors and land use/ land cover (LULC) changes in Warangal, India. The research uses the intensity of urban development in 0-2km, 2-5km, and above 5km distances around transport corridors like the National Highway 44, state highways, and regional roads using the buffer zone analysis. The findings indicate that the rate of development exponentially increases with the closeness of the corridor: urban built-up area is 72 percent in 0-2km of NH-44 and only 12 percent in the non-corridor. Accessibility index, however, is positively related to infrastructure development and population concentration (r=0.92, p<0.01). The spatial analysis shows linear patterns of sprawl along the corridor’s direction instead of concentric circle proliferation, which constitutes 64 per cent. of all the peripheral development. Land use transitions suggest that most of the agricultural loss is in the form of agricultural land conversion (58 of all agricultural loss) towards areas close to the corridors, whereas remote locations preserved the agricultural functionality. Transport corridors became the destination of 82 percent of commercial establishments as well as 76 percent of industrial establishments. The research shows that quantitatively, transportation accessibility leads to peripheral urbanization tendencies, and the impact is important on uncontrolled sprawl, loss of agricultural lands, and environmental degradation. The results indicate the use of corridor-based development control measures, limited development in the 0-2km development areas, and compact development in the planned corridors as the best measure towards sustainable urbanization in Warangal and other Indian cities.
