“…Based on the results obtained from the analysis of 9 sustainability indicators, the situation of the city-region of Mazandaran is unsustainable or in a weak sustainability situation due to the pattern of sprawl-decentralized land consumption and its high per capita land consumption, and the results obtained in this research are somewhat are consistent with what has been suggested by Dong et al (2019), Jabareen (2008 and Chakraborty et al (2022) who show the impact of the type of land consumption patterns of an region on its sustainability. In these studies, sprawl-decentralized patterns lead to increased land consumption and ultimately lead to unsustainability, and conversely, compact patterns lead to a decrease in land consumption rate and move towards sustainability.…”

“…To address the crises and negative consequences of the land consumption phenomenon, many efforts have been done to identify spatial patterns of urban expansion and land consumption at both macro-and micro-levels and analyze these patterns concerning the efficiency of land storage resources and compliance with criteria of sustainable development (Dong et al 2019;Grekousis and Mountrakis 2015;Chakraborty et al 2022). The recognition, analysis, and disclosure of the expansion patterns of built-up areas and their evaluation based on sustainable development criteria provide a basis for spatial planning and its sustainability and the promotion of policies and strategies for future urban development (Dong et al 2019).…”

Background The rapid expansion of built-up areas and land consumption with unsustainable spatial patterns in coastal urban areas has become a global major concern due to its far-reaching consequences for human daily life, environmental sustainability, and living organisms. However, the research on this phenomenon in these areas has received less attention. To fill this gap, we conducted a study to explore the spatial patterns of land consumption at both micro- and macro-levels and to evaluate its consequences in terms of sustainable development in a coastal city-region of Mazandaran Province in northern Iran. To achieve these two goals, we combined two methods of urban land density function and landscape expansion index (LEI) to explore spatial patterns of land consumption and also evaluated the sustainability of the region with two methods of the hierarchical analytical process (AHP) and urban sustainability index (USI). Results The spatial patterns of land consumption in the city-region of Mazandaran from 1996 to 2016 at the macro-level changed from a decentralized-sprawl to a centralized-sprawl pattern. At the micro-level, the dominant spatial pattern of land consumption in the city-region changed gradually from the outlying pattern towards the edge expansion and infilling patterns. Also, the spatial pattern of the built-up patches in the majority of the urban areas had conformity with the dominant pattern of the region. Besides, the spatial patterns of land consumption in the region were in an unsustainable state and were changing towards more unsustainability. The absence of urban containment policies and plans could lead to further destruction of the natural environment and increase its unsustainability. Conclusions Our results indicate that the urban areas of the coastal Mazandaran have the same behavior in the spatial pattern of land consumption at the macro- and micro-levels and all are in the same direction and follow the dominant pattern of the region.

“…At the same time, it is predicted that the degree of global urbanization will reach 69% in 2050 [17]. In the face of the unstoppable wave of urbanization, how to optimize the urbanization process and achieve sustainable urban development by improving the utilization efficiency of urban land is an urgent issue for all countries [18][19][20][21][22].…”

All over the world, Industrial agglomeration has become a key to improve the efficiency of urban land use and regulate the process of urbanization. Industrial agglomeration, as a universal economic geographical phenomenon, has been extensively studied, but few scholars have discussed the relationship between industrial agglomeration and urban land use efficiency. Based on this, after classifying the type of agglomeration externalities, our study uses OLS and GTWR models to explore the complex mechanism of interaction between industrial agglomeration externalities and urban land use efficiency, especially the spatiotemporal non-stationary characteristics. We found that the impact of industrial agglomeration externalities on urban land use efficiency is significantly unstable in time and space, and the coexistence, substitution and aging mechanism of agglomeration externalities among different types were also observed. Our research can provide reference for city managers to formulate reasonable industrial policies and enterprises to choose the location. Meanwhile, our research has made some contributions to the academic research on urban land use efficiency.

“…How cities actually grow is one of the main research questions in urban studies. The literature distinguishes three primary growth modes of urban expansion (Figure 1) (Angel et al 2021a;Chakraborty et al 2021Chakraborty et al , 2022Xu et al 2020):…”

“…• leapfrog: growth that is detached from the existing urban land extent There has been an increasing interest in empirical studies covering urban form, urban land-use patterns, and land-use efficiency (Deng et al 2021;Koroso et al 2021). Recent studies have mainly focused on Asian, African, European, and American cities (Chakraborty et al 2022;Wolff et al 2018;Xu et al 2020;Yao et al 2020). Conversely urban expansion in Latin America has received little attention, even though intense urban expansion has occurred in this part of the world in recent decades, with 81.2% of the total population living in cities in 2020 (UN-Habitat 2020).…”

Colombia has experienced rapid urbanization over the past three decades. Most Colombian cities doubled their urban extent in the last 10 years which resulted in a high demand for land. This research identifies urban expansion patterns in five of the largest urban agglomerations in Colombia. Urban growth is analysed using satellite images (Landsat 5) and census data to assess spatiotemporal land-use changes over a 30-year period . The actual urban extents are compared with each city's land-use predictions, instruments, and regulations to ascertain whether local authorities have the capabilities to predict land demand and to guide development processes at the municipal level. The predictions made by local authorities are inaccurate and often underestimate the rates of population growth and land requirements. The findings reveal that local authorities lack the capabilities to manage urban growth and deliver sustainable urban development. This is leading to poor outcomes: low planning standards, urban informality and inefficient land use.
