Abstract

Physiographically, Northeast India is located in the foothills of the Himalayas, an ecologically fragile zone. Due to its unique topography and ecosystem, rapid urban growth poses a high risk to the environment. The 11th Sustainable Development Goal adopted by the United Nations aims to promote sustainable cities and communities through sustainable urban planning practices. Therefore, this study attempts to monitor urban growth and assess the spatio-temporal urban sprawl pattern in Agartala Municipal Council, India, using geospatial techniques. The Landsat satellite images for the years 1991, 2001, 2011, and 2021 were downloaded to analyze land cover changes. The dynamics of built-up growth was assessed through the cardinal direction approach, average annual expansion contribution rate, average annual built-up growth rate, and built-up expansion intensity index. Urban sprawl and its intensity were quantified through Shannon’s entropy index. Further, urban sprawl typologies were computed, and landscape metrics identified the characteristics of urban sprawl. The results exhibited significant rise in built-up land cover, primarily at the expense of vegetation, agricultural, and fallow land covers. High intensity of urban sprawl was detected in Agartala Municipal Council. Urban fringe typology of urban sprawl was predominant. Landscape metrics revealed fragmented built-up growth, a significant rise in outward expansion, shape irregularity, and accelerated dispersion. Such studies using geospatial techniques can be the basis for planning and promoting the 11th Sustainable Development Goal in Asia and the Pacific region.
