Abstract

In developing nations, urban expansion is driven by industrialization, economic growth, and rural-to-urban migration. This study posits that urban growth is a complex phenomenon. The research employs spatial metrics to analyze urban expansion patterns in Delhi. Land cover and urban dynamics were evaluated using multi-temporal remote sensing and GHSL data from 1975 to 2020. Data analysis occurred at Landscape, Class, and Ring Buffer Zone levels. Findings reveal built-up areas increased by approximately 3.5% annually, while agricultural land and forest cover declined by 2.5% and 1.8%, respectively. The results underscore a nuanced interaction between urban expansion and land use types, highlighting agricultural conversion and non-agricultural shifts. Utilizing spatial metrics such as Shannon entropy, the study assesses urban density and growth, indicating concentrated development within 15 km of the city center. This study integrates scenario-based modeling and socio-economic indicators to assess future urban growth trajectories and their implications across Delhi NCR respectively. The findings reveal spatial disparities and socio-economic drivers of expansion, highlighting the need for equitable, sustainable urban policy interventions. This research contributes to the understanding of urbanization's ecological and social impacts, providing essential insights for sustainable urban planning in fast-growing cities.

印度大城市城市增长动态评估框架的发展：多尺度分析

在发展中国家，城市扩张是由工业化、经济增长和农村向城市迁移推动的。本研究认为城市增长是一个复杂的现象。该研究采用空间指标来分析德里的城市扩张模式。利用1975 - 2020年的多时相遥感和GHSL数据对土地覆盖和城市动态进行了评价。数据分析在景观、类和环形缓冲区级别进行。研究结果显示，建成区面积每年增加约3.5%，而农业用地和森林覆盖率分别下降2.5%和1.8%。研究结果强调了城市扩张与土地利用类型之间微妙的相互作用，突出了农业转化和非农业转移。利用香农熵等空间指标，该研究评估了城市密度和增长，表明市中心15公里内的集中发展。本研究整合了基于场景的建模和社会经济指标，分别评估了未来城市增长轨迹及其对德里NCR的影响。研究结果揭示了城市扩张的空间差异和社会经济驱动因素，强调需要采取公平、可持续的城市政策干预措施。该研究有助于理解城市化的生态和社会影响，为快速发展城市的可持续城市规划提供重要见解。

期刊介绍： Description The journal has an applied focus: it actively promotes the importance of geographical research in real world settings It is policy-relevant: it seeks both a readership and contributions from practitioners as well as academics The substantive foundation is spatial analysis: the use of quantitative techniques to identify patterns and processes within geographic environments The combination of these points, which are fully reflected in the naming of the journal, establishes a unique position in the marketplace. RationaleA geographical perspective has always been crucial to the understanding of the social and physical organisation of the world around us. The techniques of spatial analysis provide a powerful means for the assembly and interpretation of evidence, and thus to address critical questions about issues such as crime and deprivation, immigration and demographic restructuring, retailing activity and employment change, resource management and environmental improvement. Many of these issues are equally important to academic research as they are to policy makers and Applied Spatial Analysis and Policy aims to close the gap between these two perspectives by providing a forum for discussion of applied research in a range of different contexts Topical and interdisciplinaryIncreasingly government organisations, administrative agencies and private businesses are requiring research to support their ‘evidence-based’ strategies or policies. Geographical location is critical in much of this work which extends across a wide range of disciplines including demography, actuarial sciences, statistics, public sector planning, business planning, economics, epidemiology, sociology, social policy, health research, environmental management. FocusApplied Spatial Analysis and Policy will draw on applied research from diverse problem domains, such as transport, policing, education, health, environment and leisure, in different international contexts. The journal will therefore provide insights into the variations in phenomena that exist across space, it will provide evidence for comparative policy analysis between domains and between locations, and stimulate ideas about the translation of spatial analysis methods and techniques across varied policy contexts. It is essential to know how to measure, monitor and understand spatial distributions, many of which have implications for those with responsibility to plan and enhance the society and the environment in which we all exist. Readership and Editorial BoardAs a journal focused on applications of methods of spatial analysis, Applied Spatial Analysis and Policy will be of interest to scholars and students in a wide range of academic fields, to practitioners in government and administrative agencies and to consultants in private sector organisations. The Editorial Board reflects the international and multidisciplinary nature of the journal.
