“…This phenomenon can be more intense in peri-urban Mediterranean regions undergoing climate aridification and increasing anthropogenic pressure [54][55][56][57]. The empirical findings of our work confirm earlier evidence on urban growth as a factor of degradation and physical loss of soil [58][59][60][61]. In most socioeconomic contexts typical of advanced countries, consensus has been reached on the assumption that settlement expansion may concentrate on soils with high suitability for agriculture (e.g., [62][63][64][65]), determining cropland reduction and loss of approximately 2% of the world's current arable land [66].…”

Soil loss and peri-urban settlement expansion are key issues in urban sustainability, with multi-disciplinary implications that go beyond individual ecological and socioeconomic dimensions. Our study illustrates an assessment framework diachronically evaluating urbanization-driven soil quality loss in a Southern European metropolitan region (Athens, Greece). We tested the assumption that urban growth is a process consuming high-quality soils in a selective way analyzing two spatial layers, a map illustrating the diachronic expansion of settlements at five time points (1948, 1975, 1990, 2000, and 2018), and a geo-database reporting basic soil properties. The empirical results showed that the urban expansion in the Athens region took place by consuming higher- quality soil in fertile, mostly flat, districts. It entailed a persistent soil quality decrease over time. This trend globally accelerated in recent years, but in a heterogeneous way. Actually, newly built, more compact areas expanded on soils with lower erosion risk than in the past. Besides, low-density land take is likely to be observed in soils with moderate-high or very-high qualities. These evidences reflect the need for a comprehensive evaluation of complex processes of land take informing spatial planning for metropolitan sustainability.

“…The historical process of urban sprawl in western developed countries shows that urban sprawl is a market-oriented self-organization process under economic development and population growth. There is a close relationship between urban sprawl and the adjustment of urban economic structure, and the impact of changes in economic structure on climate change is also obvious [20,26]. The rationality of the economic structure is directly related to climate change, environment, and ecological improvement.…”

“…Some scholars have summarized the spatial distribution characteristics of the coupling degree between urban sprawl/urbanisation and the environment in 34 provinces (cities and districts) in China from the national level [20][21][22]. Some scholars have taken the domestic urban agglomeration as their research object to analyze the coupling relationship between urban sprawl/urbanisation and the environment in Chengdu-Chongqing region, Beijing-Tianjin-Hebei region, the Pearl River, and the Yangtze River Delta region [23][24][25][26]. Other scholars have conducted research at the provincial level to evaluated the degree of them in Beijing, Shanghai, and Chongqing [12,13,27,28].…”

In recent years, a noticeable contradiction has emerged between the disorderly sprawl and fragile climate environment of many cities, especially in mountainous cities. Therefore, this paper respectively constructed evaluation indicators for urban sprawl sustainability (USS) and climate change adaptability (CCA). Next, a coupling coordination degree model was used to measure the coordinated development of USS and CCA. Finally, this paper analyzed the coordinated development type of USS and CCA in the Chongqing metropolitan area from 2007 to 2017. The results of this paper show that USS and CCA have gradually shifted to coordinated development in the Chongqing metropolitan area during the study period. However, there were obvious regional differences in the type of coordinated development in the Chongqing metropolitan area. The coordinated development degree of USS and CCA in nine districts ranged from 0.635 to 0.721 in 2017. It can be divided into three types: slightly coordinated development with lagging CCA; slightly coordinated development with lagging USS; and moderately coordinated development with lagging CCA. Those districts should give priority to the use of Nature-Based Solutions (NBS), and multi-center and multi-group approaches to enhance the coordinated development between USS and CCA, which is also helpful for mountainous cities in China and other countries. decline of urban climate change adaptability. Therefore, ways to urban sprawl sustainability while adapting to climate change have become a key issue in urban sustainable development.Mountainous cities are cities that are distributed mainly in mountainous areas, hills and rugged plateaus, which have different urban morphologies and ecological environments than plains and plateau cities [10]. Constrained by their own unique geological, hydrological, land, ecological environments, and natural resources, mountain cities are characterized by high sensitivity, weak compressive capacity, and poor self-adaptability [10,11]. In specific times and spaces, compared with other types of cities, mountainous cities are more vulnerable to climate change. And as western mountainous cities are in a period of rapid urban sprawl-affecting urban populations, spaces, economies, and other aspects-the impacts of climate change are even more serious. Therefore, the coupling relationship of climate change adaptability and urban sprawl sustainability in mountainous cities has become an important aspect of current urban sustainable development research.Coupling is a concept derived from the physical relationship between two (or more) subjects [12]. For example, when two pendulums are connected to a spring, their vibrations fluctuate and interact with each other. This interaction is called pendulum coupling. From an ecosystem perspective, coupling refers to the interaction, mutual evolution, and subsequent development of two or more system elements (or subsystems) [12]. Similarly, the phenomenon of interaction and mutual evolution between urban sprawl and climate change syst...

“…Urban expansion has induced various problems globally. Erosion in the agricultural land [4,5] and an increase in the greenhouse gas and CO 2 emissions [6,7], urban public services expenditure [8], and travel costs [9] have been experienced globally. Especially in Japan, a decrease in the downtown population due to the population decline and population outflow to big cities has resulted in a higher population density in vast urban areas, lower than in the expanded cities.…”

Sustainable Downtown Development for the Tsunami-Prepared Urban Revitalization of Regional Coastal Cities

et al. 2019

Regional cities in Japan are facing a decline in the downtown area owing to urban expansion and a decrease in the population. Promoting downtown living is indispensable for the realization of downtown revitalization. Since many coastal cities originally developed outward from a port, their downtown areas are located near the coast and are at high risk of tsunamis. The purpose of this research is to reveal the effectiveness of dealing with the above two issues in parallel by evaluating the Deae-ru Saiwai estate, a public housing relocation project in downtown Kushiro, Hokkaido, Japan that incorporates a tsunami evacuation facility with questionnaires and a GIS survey. Placing public housing in the downtown area shortens the distance to public facilities and improves the convenience of the surrounding environment for many residents. Installing the tsunami evacuation facility improves the feeling of reassurance of residents who would feel anxiety about immigration with regards to tsunamis. This research has clarified the synergistic effect of dealing with the daily and emergency issues in parallel for promoting downtown living. Planning downtown revitalization and disaster prevention concurrently, which has been separated so far, is a fundamental planning approach for urban revitalization in regional coastal cities.
