While substantial efforts have been made to identify and address issues of environmental justice in urban areas, the question of how to consider and plan for the concerns of humans and other species remains a major challenge. This paper provides a conceptualisation of what 'justice' might mean from a multispecies justice (MSJ) perspective within the contexts of nature-based solutions (NBS) and urban sustainability planning. We offer a wider conceptualisation of representation, distribution and agency compared with dominant framings in NBS scholarship and provide exemplar cases on how to integrate these concepts in planning discourse. We critically discuss some of the challenges and opportunities of considering MSJ when confronted by established procedures and practices in NBS science and decision-making, focusing on (i) moving beyond existing standards for biodiversity conservation; (ii) embracing MSJ as a process and practice; and (iii) building the capacity of NBS planners to work with MSJ.

Adaptation to climate change is a social-ecological process: it is not solely a result of natural processes or human decisions but emerges from multiple relations within social systems, within ecological systems and between them. We propose a novel analytical framework to evaluate social-ecological relations in nature-based adaptation, encompassing social (people-people), ecological (nature-nature) and social-ecological (people-nature) relations. Applying this framework to 25 case studies, we analyse the associations among these relations and identify archetypes of social-ecological adaptation. Our findings revealed that adaptation actions with more people-nature relations mobilize more social and ecological relations. We identified four archetypes, with distinct modes of adaptation along a gradient of people-nature interaction scores, summarized as: (i) nature control; (ii) biodiversity-based; (iii) ecosystem services-based; and (iv) integrated approaches. This study contributes to a nuanced understanding of nature-based adaptation, highlighting the importance of integrating diverse relations across social and ecological systems. Our findings offer valuable insights for informing the design and implementation of adaptation strategies and policies. This article is part of the discussion meeting issue 'Bending the curve towards nature recovery: building on Georgina Mace's legacy for a biodiverse future'.

There is now widespread recognition of the need for inter/transdisciplinary (I/TD) approaches to solving global problems like climate change and biodiversity. Yet methods for successfully integrating knowledge across disciplines, and between research and practice, are in need of further development, particularly approaches that can ameliorate epistemological and ontological divides. Here we propose a framework for good listening as a ‘weak method’ that can provide guidance and structure to I/TD collaborations, but does not assume the form and goals a given collaboration will take. Synthesising the results of a scoping, interdisciplinary literature review, we highlight four key components of listening—receiving, processing, interpretation, and feedback/response—and provide a set of normative values regarding ‘good listening’ for each. Our goal is to provide a framework that is grounded in detailed scholarly discussions of listening politics and practice, but that is specifically formulated in response to the needs and concerns of I/TD researchers. We then apply our framework to four commonly encountered challenges in sustainability science, drawing on our collective experience in the field to explore how good listening can aid I/TD collaboration in regards to inclusion, group dynamics, format and pace. In doing so, we hope to inspire those working in sustainability science to approach I/TD collaboration in a new way and provide a tool for facilitating caring and transformational approaches to solving the world’s most pressing sustainability crises.

Extreme weather events are on the rise, increasingly impacting cities and their urban populations. In response, urban greening and nature-based solutions (NbS) have emerged as key approaches for reducing risks from multiple types of extreme climate and weather events while making a positive impact on urban social and environmental inequities. NbS interventions are high on urban agendas worldwide, but in practice, they often are hyper-local and contain novel ecological entities, with unknown capacity to deal with different pressures and disturbances. Thus, there is an urgent need to build knowledge around how, when, and under what circumstances different NbS can be expected to perform their functions as intended. One step towards building, and then constantly updating, such knowledge is to establish practices for monitoring and evaluating NbS.

In this study, we showcase a novel approach based on wireless sensor technology that harnesses hyperlocal data in real time to understand the direct impact of NbS on the local climate across seasonal variation and under extreme weather conditions. We aimed to quantify to what extent NbS are contributing to ecosystem services such as cooling.

To answer this, we installed eighteen microsensor weather stations across the biggest and most recent sustainable urban development in Sweden - Stockholm Royal Seaport. We investigated five distinct types of NbS - forest parks, green courtyards, rain gardens, green roofs, and lawns, during the summer of 2021 to examine whether real-time temperature changes varied between NbS site types. Despite large differences in vegetation and urban landscape, we did not observe a clear trend in air temperature differences between sites, even for experimental reference sites. Our analysis reveals that forest parks are the coolest and the green roofs are the warmest green places overall. The largest differences in daytime temperatures reached up to 2 °C difference between sites in summer, which gradually disappeared during cooler months. Our results suggest that regional weather dynamics dominate over the Stockholm Royal Seaport's micro-climate, leading to a relative similarity in NbS cooling performances. Though the district overall may be too homogeneous to affect air temperature variation and local NbS too small to alter the regional weather patterns, we nonetheless conclude that ecosystem services of NbS should not be taken for granted. Results suggest that NbS interventions, almost regardless of type, need to be considered and implemented at larger district scales to add up to the substantial total green cover needed to impact local and regional temperatures.

The design and implementation of nature-based solutions (NBS) in cities are often limited by an anthropocentric approach that prioritizes utilitarian goals instead of the diverse needs and abilities of multiple species that would support ecological flourishing. This paper starts from the premise that multispecies justice (MSJ) thinking provides a needed biocentric approach to NBS, and explores how a Capability Approach (CA) can be a bridge to integrate MSJ into urban NBS. The premise was tested through an embodied methodology used to design and deliver multi-city workshops in urban novel ecologies; settings often described as abandoned and hosting novel ecosystems. This research improved the understanding of participant’s awareness and knowledge of more-than-human agencies in shaping space and time, and in identifying social and environmental vulnerabilities and opportunities that can foster or hinder multispecies flourishing. We conclude by exploring how the CA can bridge NBS and MSJ and argue for the potential of marginal, less-valued novel ecologies as important elements of socially and biodiversity-rich urban futures.

Identifying research gaps and priorities is paramount to advance sustainability science and contribute to a sustainable future. This editorial contributes to this effort by contemplating the sustainability science research agenda and aligning it with recent changes in global dynamics. Drawing on consultations with the editorial board members of the Sustainability Science journal and a review of relevant literature, we identified 12 key research topics. These topics are interpreted within a strategic framework encompassing three key themes: (1) goals that drive sustainability science, (2) approaches to attain these goals, and (3) tools to advance sustainability science research. In so doing, this editorial emphasizes a sustainable development agenda extending beyond 2030, fostering equity and justice, and tackling issues related to power dynamics and geopolitical conflicts. It underscores the significance of research approaches to attaining sustainability goals, in particular, theorizing, co-production of knowledge and action, attaining clarity in conceptual descriptions, and developing systems-oriented analytical frameworks. Additionally, it highlights the value of place-based approaches, learning from significant systemic shocks, and nurturing inner transformations. It also underlines the need to explore emerging technologies and data-intensive methodologies as a tool to address sustainability concerns. The systematic contemplation of the sustainability science research agenda presented in this editorial piece aims to invoke further discussion among researchers and practitioners about a fresh and relevant agenda that promotes the sustainable integration of nature and society.

Peri-urban landscapes are the meeting point of a wide range of human activities, power dynamics, and social-ecological processes in the Anthropocene. Multiple interests, as well as differences in governance regimes and decision-making processes increase the complexity of peri‑urban landscapes. With this complexity as a background, we place our focus on the interactions between two highly desirable human activities in peri‑urban landscapes: outdoor recreation and biodiversity conservation. The multifunctional role peri‑urban landscapes can fulfill to respond to biodiversity conservation and outdoor recreation goals has the capacity to minimize the potential clash between these two functions. Despite this, little attention has been paid to the realization of multifunctionality in peri‑urban landscapes when addressing the recreation-conservation nexus. In this Perspective, we provide a foundation for further inter-disciplinary explorations in this area by identifying knowledge gaps and priorities for future research on the recreation-conservation nexus in peri‑urban landscapes with particular emphasis on the “spatial” dimension.

Increasing evidence demonstrates the psychological benefits of nature contact. However, the evidence is often established at the population level, and the individual differences in the psychological benefits gained from nature are considered negligible variations. In this study, we performed a cross-sectional online survey in Brisbane and Sydney, Australia, from April 15th and May 15th, 2021 around one year after the first covid-19 pandemic lockdowns. The results show that individuals with a stronger connection to nature are linked with a lower level of stress and anxiety with increased frequency in public greenspace visits, while such an association is less clear for individuals with a weaker connection to nature. We also find that, through the answer to an open-ended question, individuals with a lower connection to nature tend to mention nature-related words less as the reason for visiting greenspace. This indicates that a person’s connection to nature is linked with how they interact with nature and thus might determine whether and how much psychological benefit a person gains from experiencing nature.

In an increasingly urbanized world, the concepts of ecosystem services and nature-based solutions can help tackle grand challenges. However, ambiguity in their definitions and in the relationship between the two concepts complicates comprehensive research efforts as well as their effective application in policy and planning in urban systems. This paper presents a framework to clarify and explicitly relate the two concepts, enhancing their applicability in the management of urban challenges. Within the framework, addressing urban challenges serves as the starting point for the development and implementation of nature-based solutions. Nature-based solutions alter the flows of ecosystem services that are produced by an ecosystem by altering the performance of the ecosystem or by changing how people engage with the ecosystem. This results both in changes in the target ecosystem services, as well as non-targeted ecosystem services, leading to benefits. Using two illustrative case studies, we show how the framework can be applied to two urban challenges that are expected to increase in intensity in cities across the world: stormwater management and urban heat stress. Moreover, we highlight key research topics that will benefit from more integrated use of nature-based solutions and ecosystem services. The framework helps emphasize co-benefits, and can be used to help make co-benefits and multifunctionality explicit in urban decision-making and planning processes.

Understanding residents’ perceptions of green-blue infrastructure (GBI) is critical to ensure continued access to its associated benefits in growing and densifying urban landscapes. Physical availability and accessibility of green spaces alone do not directly translate to actual appreciation and use. Residents’ sense of place can determine if benefits from GBI are realized and how landscape changes may be perceived. In this study, set in sub-urban Stockholm, Sweden, we applied a mixed-methods approach combining mental mapping with follow-up interviews to investigate how such methodology can improve our understanding of residents’ perception of the recreational use of GBI. For the mental mapping exercise, participants drew, freehand, a map of appreciated neighborhood places for recreational purposes. Our results clearly show that mental mapping provides relevant information on individual and collective perceptions of recreational GBI, linkages between green-blue and gray infrastructure elements, and recreational hot-spots of importance to the local inhabitants. The unguided approach to welding local knowledge with spatial expressions makes the method well suited to contribute to a better understanding of plural senses of place with regards to the recreational use of GBI in rapidly urbanizing landscapes and an enhanced capacity to recognise locally appreciated recreational spaces in planning and practical management.
