“…Most of the previous studies on resilience emphasized the influence of infrastructure and socio-economic factors, thus these factors were often selected for exploring resilience [ 6 , 33 ]. However, after a literature review, it was found that traditional knowledge plays a significant role in coping with climate change in certain areas.…”

The impact of climate change in recent years has caused considerable risks to both urban and rural systems. How to mitigate the damage caused by extreme weather events has attracted much attention from countries in recent years. However, most of the previous studies on resilience focused on either urban areas or rural areas, and failed to clearly identify the difference between urban and rural resilience. In fact, the exploration of the difference between the resilience characteristics of cities and villages under climate change can help to improve the planning strategy and the allocation of resources. In this study, the indicators of resilience were firstly built through a literature review, and then a Principal Component Analysis was conducted to construct an evaluation system involving indicators such as “greenland resilience”, “community age structure resilience”, “traditional knowledge resilience”, “infrastructure resilience” and “residents economic independence resilience”. Then the analysis of Local Indicators of Spatial Association showed some resilience abilities are concentrated in either urban or rural. Binary logistic regression was performed, and the results showed urban areas have more prominent abilities in infrastructure resilience (the coefficient value is 1.339), community age structure resilience (0.694), and greenland resilience (0.3), while rural areas are more prominent in terms of the residents economic independence resilience (−0.398) and traditional knowledge resilience (−0.422). It can be seen that urban areas rely more on the resilience of the socio-economic structure, while rural areas are more dependent on their own knowledge and economic independence. This result can be used as a reference for developing strategies to improve urban and rural resilience.

“…Liu et al, 2021;Nigro et al, 2019). Urban vulnerability is currently addressed from the perspective of ecosystem assessment or urban conversion zones to improve the management of specific areas such as coastal regions (Bianco & García-Ayllón, 2021;Ghosh & Das, 2019;Li et al, 2016), without an analysis of the urban morphology in relation to the mobility network, such as infrastructure axes and urban development. These studies essentially focus upon the environment and do not contain the in-depth socio-spatial dimension as an analytical component.…”

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.

“…Coastal cliffs environments naturally undergo morphological changes at different scales, with erosion times occurring in response to different forces. The morphological state and development caused by human pressure and natural processes can be assessed using several indicators (Araújo Queiroz et al, 2022; Bianco & García‐Ayllón, 2021; Giardino et al, 2014; Paula, Lima, et al, 2021). Van Koningsveld & Lescinski (2007) highlighted the existence of 15 coastal state indicators capable of effectively describing the dynamic state and evolutionary trends of the coast.…”

Assessing historical changes in the shoreline and retreat of cliffs is essential for understanding the evolution and behaviour of specific coastal systems. The present study focused on shoreline changes and cliff base retreat trends at different time scales (annual/decadal) along a 680‐m stretch of Pacheco Beach (Caucaia, Northeast Brazil), which are characterized by coastal erosion and mass movements that have posed risks to residents and visitors to this beach. Shoreline position data were obtained through images collected by satellites and field campaigns for precision mapping through unmanned aerial vehicle (UAV) photogrammetry. The spatiotemporal variations of the shoreline were acquired through an extension of the ArcGIS Digital Shoreline Analysis System (DSAS) and the linear regression rate (LRR) statistical method that reflects the variations that have occurred in the coastal segment. The long‐term results show constant erosion patterns in the study area, with a shoreline retreat of −31 m in the last 17 years at an average rate of −1.8 m/year. In the short term, the average rate of retreat between May 2021 and Jan 2022 was −2.9 m, indicating that 88.78% of the evaluated section was in a continuous process of erosion. Several factors and processes cause the short‐term rates to be more severe than historical rates, demonstrating the stochastic nature of the Pacheco Beach cliff system. This research provides essential data for understanding and predicting shoreline changes on different time scales, thereby contributing to the identification and zoning of unstable cliffs and allowing for the mapping of risk areas to direct coastal management strategies.
