“…The development and expansion of built-up areas is a systematic process affected by many uncertain factors. Scholars [35] point out that the dynamic factors of urban spatial expansion include natural conditions [36], urban economic development [37], urban population growth [38], urban transportation network development [39], government policy intervention, etc., and the expansion of built-up areas in Nanjing is also driven and restricted by these factors. Along with our country in the 21st century, the development of science and technology and improvements to national planning regulations [40] have led to the natural conditions of urban construction direction gradually becoming smaller while the influence of urban economy, urban population, and government planning and policy factors that affect the direction of urban construction has increased.…”

The fast development of urban built-up areas in China is causing many problems, such as pollution, congestion, etc. How to effectively evaluate the coordination between urban areas and environmental problems has been attracting many scholars worldwide. This paper intends to discover this “secretary” through investigating the built-up areas and their accompanied economic and environmental factors over almost 30 years (1992 to 2020) in Nanjing, China. DMSP/OLS nighttime lights images from 1992 to 2013 and the NPP/VIIRS nighttime lights images from 2012 to 2022 are used for extraction of built-up areas. A spatiotemporal evolution model is established to evaluate whether the built-up areas have developed in coordination and the relationship between urban built-up areas and various factors, including compactness, the fractal dimension, boundary and shape changes, exhaust emissions, and the production of general industrial solid waste, which was further investigated to ascertain whether there was coordination or not. The investigated results discovered that Nanjing’s built-up areas had maintained continuous growth from 1992 to 2020, with the compactness of built-up areas gradually decreasing from 0.42 to 0.23 and the built-up differentiation dimension changing from 1.31 to 1.39, demonstrating that built-up areas had gradually moved from a loose pattern to a compact pattern and from irregular development to balanced development in all directions. The macro model of the coordination index change trend is 0.847 from 1995 to 2020, which indicates that the coordination between urban built-up areas of development and their environments has been improving; however, the reduction in urban green space, the increase in waste emissions, and the increased production of general industrial solid waste has raised questions regarding sustainable development.

This paper provides an analytical framework for the study of spatial income dynamics using the classical measures of $$\sigma$$ σ -convergence (reduction in dispersion) and $$\beta$$ β -convergence (poor areas grow more quickly than rich ones) linked by a re-ranking metric and reinterpreted based on the ‘leave no one behind’ principle. Our approach allows identifying the contribution of each territorial unit to each of the three facets of distributional change ($$\sigma$$ σ -convergence, $$\beta$$ β -convergence, and re-ranking), as well as gauging the part of each component of distributional change that corresponds to geographically neighbouring and non-neighbouring units. We illustrate our proposal by examining convergence across the census tracts of Malaga – the sixth most populated city of Spain – before and after the COVID-19 pandemic. We find that while income convergence across Malaga’s census tracts tended to improve over the period 2015–2019, this process was interrupted during the first year of the pandemic, affecting some specific census tracts. We examine our outcomes by grouping the results into deciles and districts made up of specific census tracts. Finally, we analyse the impact of neighbours on regional convergence and each of its components. This spatial decomposition highlights the crucial role of the spatial component in the convergence process.

This study aims to assess the progress towards Sustainable Development Goal 11 (SDG 11) in Al-Madinah Al-Munawwarah, Saudi Arabia. The study also examines challenges that encounter SDG 11. To this end, six targets consisting of 40 indicators of SDG 11 have been adopted, relying on literature, international and national technical reports, and the personal perspectives of twelve experts. Overall progress towards SDG 11 has shown significant improvement considerably, with a middle level, particularly after Saudi Vision 2030 was approved. The findings show that three targets including affordable housing, sustainable transportation, and sustainable urbanization and participation, have achieved average progress, and two targets, including air quality, and waste management, and access to green areas have been demonstrated poor progress, as well as a single target, which is the preservation and protection of natural and cultural heritage, which has achieved relatively optimal progress. The results highlight several challenges that hinder progress towards SDG 11, but the level of these challenges varies from one target to another target, ranging from minor to major challenges. These challenges should be considered in continuing urban strategies and could be reduced by establishing resource-saving and innovative community urban renewal programs.
