Abstract

Rapid urbanization urges the immediate attention of policymakers to ensure sustainable city development. Understanding the urban growth drivers is essential to address effective strategies for urbanization-related challenges. This work aims to study Raiganj’s urban development and the factors associated with this expansion. This study employed global logistic regression (LR) and geographical weighted logistic regression (GWLR) to explore the role of different factors. The results showed that the role of the central business district (covariate >-1), commercial market (covariate >-3), and police station (covariate >-4) were significant to the development of new built-up areas. In the second period, major roads (covariate >-2) and new infrastructures (covariate >-4) became more relevant, particularly in the eastern and southern areas. GWLR was more accurate in assessing the different factors’ impact than LR. The results obtained are essential to understanding urban expansion in India’s medium-class cities, which is critical to effective policies for sustainable urbanization.

基于遥感技术和地理加权模型的印度中等城市群城市扩张驱动因素研究

快速的城市化促使决策者立即关注确保城市可持续发展。了解城市增长驱动因素对于应对与城市化相关的挑战的有效战略至关重要。这项工作旨在研究Raiganj的城市发展以及与这一扩张相关的因素。本研究采用全球逻辑回归（LR）和地理加权逻辑回归（GWLR）来探讨不同因素的作用。结果表明，中央商务区（协变量>；-1）、商业市场（协变量>；-3）和警察局（协变量&lgt；-4）对新建成区的发展具有显著作用。在第二阶段，主要道路（协变量>；-2）和新基础设施（协变量>；-4）变得更加相关，尤其是在东部和南部地区。GWLR在评估不同因素的影响方面比LR更准确。所获得的结果对于理解印度中等城市的城市扩张至关重要，这对可持续城市化的有效政策至关重要。

期刊介绍： Geography and Sustainability serves as a central hub for interdisciplinary research and education aimed at promoting sustainable development from an integrated geography perspective. By bridging natural and human sciences, the journal fosters broader analysis and innovative thinking on global and regional sustainability issues. Geography and Sustainability welcomes original, high-quality research articles, review articles, short communications, technical comments, perspective articles and editorials on the following themes: Geographical Processes: Interactions with and between water, soil, atmosphere and the biosphere and their spatio-temporal variations; Human-Environmental Systems: Interactions between humans and the environment, resilience of socio-ecological systems and vulnerability; Ecosystem Services and Human Wellbeing: Ecosystem structure, processes, services and their linkages with human wellbeing; Sustainable Development: Theory, practice and critical challenges in sustainable development.
