Cities have been built on the benefits of density, proximity, and connectivity. However, the recent COVID-19 pandemic, along with continuously evolving communication technologies, has seen an increase in vacancies and underuse of urban buildings, challenging the agglomeration benefits of cities and our understanding of business-as-usual. By reflecting on these continuous changes in our urban environment, we can better understand the dynamics in play, the various user needs, the temporary or permanent nature of these changes, and possible adaptive strategies to navigate our future toward a more sustainable and resilient state. This article, therefore, presents a systematic literature review, using PRISMA, to examine and map how vacancy intersects with adaptive reuse literature. This review examined 43 academic articles and revealed research predominately focusing on whole-building adaptive reuse of completely vacant buildings. This review highlighted that vacancy is mainly assumed in research, and both vacancy and adaptive reuse are insufficiently unpacked. A new adaptive reuse framework is proposed to address the misalignment between the realities of how a vacancy is distributed in building stocks and the focus on whole-building adaptive reuse. The framework is set to inform urban policy development supporting sustainable reuse. This article presents a point of departure to understand how adaptive planning approaches could be applied to enhance broader sustainability and resilience initiatives.

Human population and cities are growing fast, with a concomitant modification of the land surface. Urbanization is driving biodiversity loss and biological homogenization, which impacts human wellbeing. In this study, we evaluated the influence of urbanization on flower visitor assemblage using an interaction network approach. We assessed the effect of different variables at the local and landscape scales on community parameters and network metrics along a gradient of urbanization located in a subtropical montane Yungas forest. We found that local variables affected the richness of flower visitors, which increased with greater flower coverage, high stability of floral resources, and the proportion of exotic plants. Moreover, local variables affected the diversity, nestedness (NODF), and specialization (H2) of the interaction network. Landscape variables, such as altitude and proportion of impervious surface (a proxy of urbanization), affected both the richness of flower visitors and specialization. The effect of urbanization on the richness of flower visitors differed across the altitudinal gradient, with higher impact at higher altitudes. In conclusion, our results indicate that local and landscape variables affect community parameters and the structure of plant-flower visitor networks to different extents and strengths.

Urban greenery has been shown to impact the quality of life in our urbanizing societies. While greenery is traditionally mapped top-down, alternative computational approaches have emerged for mapping greenery from the street level to mimic human sight. Despite the variety of these novel mapping approaches, it has remained unclear how well they reflect human perception in reality. We compared a range of both novel and traditional mapping methods with the self-reported perception of urban greenery at randomly selected study sites across Helsinki, the capital of Finland. The mapping methods included both image segmentation and point cloud-based methods to capture human perspective as well as traditional approaches taking the top-down perspective, i.e., land cover and remote sensing-based mapping methods. The results suggest that all the methods tested are strongly associated with the human perception of greenery at the street-level. However, mapped greenery values were consistently lower than the perceived values. Our results support the use of semantic image segmentation methods over color segmentation methods for greenery extraction to be closer to human perception. Point cloud-based approaches and top-down methods can be used as alternatives to image segmentation in case data coverage for the latter is limited. The results highlight a further research need for a comprehensive evaluation on how human perspective should be mimicked in different temporal and spatial conditions.

The present paper addresses the timely need, across research and practice, to ask: how do we plan sustainable and healthier cities in a synergetic way for everyday life? Currently, urban dwellers are facing significant health challenges, especially physical inactivity. There is increasing awareness of the need to initiate active living strategies for urban dwellers to confront this challenge. Active mobility—walking and cycling—is the core of active living strategies and is promoted as both a type of physical activity and a mode of transport. However, uptake of active mobility faces many barriers, including lack of motivation and longer travel times. This paper unfolds the potential of green spaces as Third Places that can potentially counteract the challenges and in return, deliver double-layered health benefits. The sensory experiences provided by urban green spaces and associated health benefits have been largely investigated; yet, little is focused on how these experiences can be integrated as a part of daily living activities. This paper gives voice to everyday practice and discusses how these experiences can be utilized as planned motivations for the use of active mobility. This paper aims to contribute to the knowledge for future research and practice, and bring forward an open debate about healthier cities, which can bridge all related professions across urban sectors.

This paper describe the lifestyle about Eco-immigrants after relocated into city during the implementation of Sanjiangyuan ecological protection plans, and study the social adaptation and change of ideas about Eco-immigrants in the rapid urbanization. Then the author thinks that the lifestyle of immigrants presents heavy traditional characteristics because lack of prominent pluralism, little social mobility, low occupational differentiation, and heterogeneity. At same time, Eco-immigrants experience cultural oscillation and forms marginal personality in social and culture adaptation process, due to the slow process of rationalization, secularization, without forming a stable and complete market economy and urban lifestyle, urbanization of Eco-immigrants is at the primary stage.

We investigated the influence of landscape cover on urban bee community functional groups. We observed a diversity of functional groups across primarily forested and primarily urban sites, however particular species were favored by forest/urban spaces. Results point to the importance of further investigating the nuance of land use impacts on pollinator communities, and in particular demonstrates the merit of investigating landscape heterogeneity. Conservation of forest remnants in urban environments can positively impact wild bees across multiple functional groups.

Urban studies in recent decades have acknowledged that the cities of the Global South are epistemically, methodologically, and empirically different. However, the theorizations of Southern cities continue to be considered outside mainstream urban theories. In addition, there remains discrepancies and imbalance in the production of scholarships in southern cities. In addition to Southern urbanism knowledge being predominantly produced in the geographical West, scholars based in the Global South experience growing marginalization as a result of access, affordances, and knowledge production politics. With increasing discussions around the politics of visibility and institutional affiliations, this study aims to systematically map and analyze the dynamics and geography of knowledge production in the field. First, a scientometric review of this study unpacks the plethora of urban theory and related publications that theorizes the Global South and places them according to where and by whom this was published. Second, this study traces the need for urban theory and the production of knowledge following the decolonization agenda to be produced by and for the south. Finally, it closes by addressing the ways forward to progress urban theory and empirics from the south through the production and coproduction of knowledge for and by the south.

As a concept, urban commons offer new perspectives on collaborative urban design and the participatory management of urban resources. In many cases, citizens create urban commons as bottom-up initiatives, although they often cooperate with local governments or private proprietors, particularly if a long-term perspective is targeted for their project. Urban commons therefore shed light on the tension between bottom-up initiatives and the public and private sector in urban governance. This article aims to better understand how the interrelation between different variables, such as the implementation process, accessibility of the community, ownership structure, etc., can help to constitute sustainable governed commons. To do so we investigate three case studies of commons in different urban settings by means of field research and interviews with activists. Each case study is evaluated in terms of sustainable governance by identifying enhancing or constraining variables, external conditions, and internal challenges. By analyzing the specific strategies for the different commons using the overarching categories of scale, permeability, and organization, we identify variables that, when combined, can lead to a sustainable managed urban commons. Comparing the different examples makes it possible to assess the limits and possibilities of sustainable urban commons governance.

This study provides a synthetic overview of thirty years of research devoted to urban climate change in Africa. Which cities in Africa are being researched on the impacts of climate change affecting them? What are the main social and urban issues and how are they linked? Is the development of climate services envisaged for these cities? Related to which local issues? Some answers are drawn by text mining the metadata of more than a thousand articles published in the 1991–2021 period and recorded in the Web of Science. The evidences produced are based on the design and exploitation of a taxonomy of keywords forming a set of issues and on their articulation in a network based on their co-occurrences in the articles' metadata. Forty-eight African countries and 134 cities are cited, Cairo, Dar es Salaam, Cape Town, Accra, Lagos, Durban, Nairobi, Addis Ababa, Kampala and Johannesburg being the cities deferring the largest number of studies. The salient urban climate change issues-health, water, energy, social issues and governance, followed by agriculture and food, mitigation, heat, urban territories, risks and hazards-are generally addressed in their interdependences. Urbanization and the implementation of associated policies, as well as the management of water resources, floods health and energy, and land use and land cover changes to a less extent, are proving to be the most pressing challenges. In view of the intricacy of these issues, climate services appear underdeveloped in African cities and barely confined to the acquisition and modeling of environmental data for decision-making in adaptation planning.
