“…Monitoring of changes using remote-sensing technology is widely used in different applications such as land use/land cover change, urban sprawl, and vegetation change (Natesh et al, 2022) become necessary to study the pattern of change in various regional types and various spatial scales for discussion of the mechanism of land use change Pandey 2021). Conversion of these natural lands into these impervious built-up lands can have significant impacts on the ecosystem, thus affecting the hydrologic system, biodiversity, and climate, and consequently may have a negative impact such as the urban heat island phenomenon (Xu 2008).…”

Urban sprawl is the growth of a settlement that occurs during urbanization. Guwahati city, located in the Kamrup Metropolitan District of Assam, India, is the hub of the northeastern states. To examine urban sprawl and the rate of population expansion during the past 30 years, research has been conducted to determine the built-up land characteristics. A temporal study using satellite images for two different years (1990 and 2020) has been carried out through GIS and remote sensing techniques, supervised classification using maximum likelihood for land use land cover preparation and raster calculator has been used to delineate NDVI and the Urban Index. The city has been divided into five buffer zones from the central growth point, and the sprawl has been analyzed for each buffer zone. The city's growth is so drastic that the built-up area has increased from 27.18% in 1990 to 47.87% in 2020. Zone-wise, the most remarkable changes have been seen in zone 2 and zone 5, up to 28.95% and 22.62%, respectively. Zone-3 counts as the minor changes in the built-up area, i.e., 6.2% due to the Ramsar site named Deeparbeel. This study will help urban planners understand the nature of sprawl and develop a feasible solution.
