“…It is well known that most of previous studies on GV dynamic have focused on the changes in the number of GV and its corresponding ESs changes (Grimm et al 2008;Wickham et al 2010;Yu et al 2020;Zhang et al 2020a;Zhou et al 2021). Although, pattern of the quality of GV (Sun and Chen 2017;Wang et al 2019;Yu et al 2019b).…”

Contexts. To quantify the ecosystem service (ES) changes caused by the dynamic of green vegetation (GV) during rapid urbanization, it is necessary to fully understand the ‘real’ conversion pattern of GV, yet key and ‘real’ conversion patterns within specific periods and contributions to GV quality remain poorly understood. Objectives. Here we use Normalized Difference Vegetation Index (NDVI) as a mediator to represent GV quality. Land cover transfer matrix (LCTM) and urban greenspace dynamic index (UGDI) were employed to fully understand the GV dynamic from quantity-quality and gain-loss perspectives. The Pearl River Delta Metropolitan Region (PRDMR), one of the fastest urbanizing regions in the world, was selected as a case study. Results. We found that from 1990 to 2015, built-up land, forests and grasslands has the most dynamic conversion, and also has the most significant impact on NDVI. The NDVI value of the newly-built forest (0.29) was much lower than that of the lost forest (0.5), which demonstrate the value and importance of existing natural forest ecosystem, as newly-built forest does not provide the same quality of NDVI and ESs. Hence, we reconfirm and suggest that in regional ecological planning and management, in addition to creating new, higher quality GV, it is essential to protect existing natural forest ecosystems. Conclusions. The study proposed new and full perspectives, including quantity-quality and gain-loss angle of view, enhance the understanding of GV dynamic and can be used in other related analyses. Results also provide important theoretical bases for regional ecological planning and protection of existing natural forest ecosystems.

“…Environmental studies conceive urban vulnerability as the result of, or exposure to, climate hazards affecting the population, infrastructure, and urban activities in general (Eakin & Luers, 2006;Romero Lankao & Qin, 2011). Finally, studies focusing upon urban resilience seek to identify short or long-term coping mechanisms to deal with these effects (Zhang et al, 2020). These vulnerability challenges highlight the need for cities to rethink how people are protected, how infrastructure investments are prioritized, and how to include climate in cities' long-term growth and development plans (Rani et al, 2020).…”

Identifying the Social Urban Spatial Structure of Vulnerability: Towards Climate Change Equity in Bogotá

The constant modification of land use, economic instability, environmental factors, and social behaviour changes among the inhabitants of big cities characterize current urbanism. In Colombia, land-use planning processes supported by geographical information systems are a recent phenomenon and the legal instruments of spatial planning are inadequate in most municipalities. Moreover, socio-spatial equity represents a challenge for Latin American cities in which there is increasing awareness of the role that spatial planning plays. Consequently, the question arises as to how the urban spatial structure and organization contribute to an inclusive and equitable socio-spatial evolution, considering climate change impacts. The case study analysed in this article focuses upon the northern limits of the city of Bogotá. Therefore, this research aims to define the ideal balance of urban land-use distribution between social stratum classification and the vulnerability of the communities seeking to better adapt to climate change. We propose a methodological approach of analysing spatial syntax and the (social) intensity of activities and infrastructure, which enables us to characterize the urban structure itself and identify vulnerable urban instances. As a result, we find that the urban network with low values presents spatial unpredictability in its pattern, constraining equitable development based on the urban morphology of the city. This research allows us to conclude that the degree of vulnerability encountered by the social urban spatial structure is higher in expansion areas than in central areas of the city.

“…Inequalities in economic growth and patterns of agglomeration have been extensively verified worldwide [ 3 , 45 ]. Due to various urbanization processes, diverse urban planning and construction philosophies, and unique geographical contexts, the accompanying urban greening is also heterogeneous in time and space [ 46 , 47 , 48 , 49 , 50 ]. In summary, both economic growth and urban greening should be characterized in terms of regional inequalities and spatial aggregation.…”

Balancing economic growth with environmental protection is vital for the sustainable development of cities and regions. However, urban greening has rarely been considered in extensive studies. This study incorporates urban greening into a coupling coordination degree (CCD) model, in order to evaluate its coordination with economic performance. A total of 286 cities in China between 2005 and 2019 were selected as specific study subjects. Meanwhile, clustering method was used to classify different clusters based on CCD values, the Gini coefficient analysis was applied to discover the CCD values inequality characteristics and the exploratory spatial data analysis (ESDA) method was employed to study the CCD values spatial aggregation features. The results indicate that the CCD values presented significant spatial heterogeneity. Spatially, the CCD values were divided into eight clusters, with those in the eastern region generally being higher than in the central and western regions. Temporally, the CCD in all cities showed an increasing trend, but more than 60% of cities were still in the uncoordinated or low-level coordination stage. In addition, inequality and spatial aggregation characteristics were observed in CCD values, both of which presented decreasing trends. Greening has a stronger influence on the linked and coordinated growth of the two systems; therefore, we propose policy recommendations for pursuing the development of environmentally friendly cities from different aspects. In summary, this research allows for a better understanding of economic and environmental relationships, thus contributing to the objective of creating sustainable cities and communities.
