Abstract : Urban sprawl is synonymous with the city’s expansion towards its suburbs, which encompasses rural areas. The rise of a city’s population causes a change in the spatial pattern of the existing land cover of the urban areas. It is also proportionally related to reducing the agricultural land, forests, and water bodies. Change in the Spatio-temporal dynamics of urban sprawl plays a significant role in the management of urban growth globally. This haphazard growth hampers proper development of the urban areas. In present times, access to high-resolution satellite imageries has led to the popularity of remote sensing and GIS technologies in monitoring urban sprawl. According to the census of 2011, Patna has experienced urbanization at 43 percent. Being the capital of Bihar, the city has witnessed a massive influx of population mainly due to rural-urban migration in search of employment opportunities, resulting in the physical extension
of the city. However, it has not been able to match the pace of population growth in infrastructural facilities and services. This has resulted in deterioration of quality of water resources, reduction in areas under urban greens, growth of slums, etc. So, to understand the gaps and provide possible solutions for better city management, the study of the pattern of urban-built-up expansion is redundant. In the present study geospatial approach is used to delineate the urban sprawl growth pattern in Patna Municipal Corporation. The study area will be bifurcated into several concentric buffer zones from the city’s center. The urban sprawl will be analyzed by measuring built-up density in each concentric buffer zones. The study will help recognize the spatial and areal dimension that needs change and better organization for future planning.
