Worldwide many crop varieties are considered seriously threatened while management strategies are still lacking. Goals and indicators relevant to the conservation of agrobiodiversity also remain to be developed. Here we present the results of three expert workshops in Peru designed to prioritise for conservation crops with high infra-specific diversity, along with the establishment of in-situ on-farm conservation goals and indicators. Analysing the results of a series of agrobiodiversity-related Payments for Ecosystem Services (PES) interventions realised between 2010 and 2021, “gaps” between current conservation status and the conservation goals are established. The identification of such gaps within the Peruvian regulatory framework is indispensable for justifying long-term government funding. Furthermore, the goal and indicator development processes initiated in Peru could also form a template for other countries, with a view to supporting the implementation of a range of international treaties, conventions and development goals.

Urban foraging for wild plant and animal products is increasingly recognised for its multiple benefits for people and nature stewardship. Planning for foraging in urban greenspace is one way that foraging can be made more accessible, beneficial, and equitable. Here, we explore how foraging could be recognised and provided for in urban municipalities in eastern South Africa. We synthesise forager and land manager interviews, policy analysis, and iterative discussions to develop four land use configurations under which foraging could be planned for. Design principles for community-based natural resource management are used to assess the feasibility of each configuration. We identify stakeholders who would be involved in governing each configuration, and how urban foraging can co-produce desirable outcomes for their priorities. We list locally-specific actions to enable collaborative greenspace governance through urban foraging. We suggest some generally applicable design considerations and implications for each of the four configurations.

Forests’ ability to provide opportunities for recreation is an important ecosystem service. This has prompted attempts to create indicators to assess forests' suitability for recreation, although hitherto with limited success. This study introduces a novel framework for indicators of potential and realised recreational values of forests, with a primary focus on Sweden and Fennoscandia. We divided forest attributes into intrinsic qualities (i.e. the structure and composition of the forest), extrinsic qualities (i.e. the location of the forest in relation to other components of the landscape), and facilitation qualities (i.e. the presence of recreational infrastructure). Using Fennoscandia as a case study, we performed a literature review to find specific indicators of recreational values, as well as evaluate the current availability of spatial data suitable to map the forest qualities on a national scale. The most important intrinsic quality we identified was tree size/age, whereas for extrinsic quality it was proximity to water. Systematic monitoring of recreational use is essential to estimate realised recreational values. The conceptual framework proved to be a valuable tool for identifying potential indicators, and applying it in other regions is likely to yield useful outcomes.

Research on urban ecosystem services (ES) covers many regions globally, yet significant gaps remain in several areas, including Russia. Furthermore, the number of publications on Russian ES is still very low, and most of them focus on ES assessment on the national level which results in an incomplete understanding of ES provision in Russian cities. To fill this gap, 197 publications on urban ES have been systematically reviewed. Those mostly included research on urban ES in Russia as well as in other cities of the world that represented case studies within international collaborations of Russian scientists with other partners. The paper presents the main aspects of the ES concept adoption and operationalizing in the Russian scientific discourse, by providing an overview of the current research on the relationships between humans and urban ecosystems. Spatially, the majority of studies focused on large cities; herewith field surveys, statistical analysis, expert evaluations, and mapping were often used as the main research methods. Four key challenge areas have been revealed: anthropogenic pressure on soils and vegetation, urban green spaces (UGS) and their quantity and quality for ES provision, the value of ES assessment for urban planning, and payments for ES. To address these challenges, future research should focus on the role of urban ES for city resilience and sustainability, ecosystem disservices, rural–urban interactions, broader testing and validation of ES mapping and assessment as well as better integration of ES in economic, regulatory and compensation mechanisms.

In many transdisciplinary research settings, a lack of attention to the values underpinning project aims can inhibit stakeholder engagement and ultimately slow or undermine project outcomes. As a research collective (The Careoperative), we have developed a set of four shared values through a facilitated visioning process, as central to the way we work together: care, reflexivity, inclusivity, and collectivity. In this paper, we explore the implications of a values-centered approach to collaboration in food system transformation research. The paper presents two cases that illustrate how researchers might approach centering values in practice. Where much research on food system transformation focuses on values of food system stakeholders, we contribute insights into the values of researchers in such transdisciplinary endeavors. Specifically, we argue that researchers working on sustainability transformations need to be better prepared to engage in such reflections and aspire to embody values aligned with the transformations they seek to research.

In complex Social-Ecological Systems (SES), the interplay between ecological and social components shapes trajectories that impact human well-being and ecosystem services. While SES dynamics have been studied in static conditions, there has been less attention to how said systems respond to shocks and stressors over time and space. This special issue presents a collection of articles that use diverse methodologies—ranging from system dynamics modeling to participatory approaches—to analyze past SES changes and discuss future scenarios. Case studies from regions including Brazil, Colombia, Mexico, Honduras, Chile, Ethiopia and Mongolia illustrate key variables influencing social–ecological transitions and provide insights into potential policy strategies to support sustainable SES. The studies underscore the need for multi-scalar approaches to SES research that explicitly theorize and empirically assess trajectories across space and time.

To address climate change and global biodiversity loss, the world must hit three important international conservation targets by 2030: protect 30% of terrestrial and marine areas, halt and reverse forest loss, and restore 350 Mha of degraded and deforested landscapes. Here, we (1) provide estimates of the gaps between these globally agreed targets and business-as-usual trends; (2) identify examples of rapid past trend-shifts towards achieving the targets; and (3) link these past trend-shifts to different levers. Our results suggest that under a business-as-usual scenario, the world will fail to achieve all three targets. However, trend-shifts that rapidly “bend the curve” have happened in the past and these should therefore be fostered. These trend-shifts are linked to transformative change levers that include environmental governance, economic factors, values, and knowledge. Further research on trend-shifts, as well as bold action on underlying levers, is urgently needed to meet 2030 global conservation targets.

Urban periphery watersheds play a crucial role in providing diverse ecosystem services, especially hydrological services (HES), for society at different temporal and spatial scales; moreover, local populations directly influence ecosystem functionality through their decisions and actions. The interactions between social and ecological factors create social–ecological systems (SESs), whose trajectories continuously change in response to internal factors such as land use cover change (LUCC) and external factors such as climate change (CC). This situation influences the vulnerability of SESs in terms of exposure, sensitivity and adaptation capacity. In this study, the social–ecological vulnerability (SEV) of the periphery of Mexico City was investigated based on the Collaborative Protocol for Ecosystem Services Assessment and Social–ecological Vulnerability Mapping (ECOSER) and a quantitative method approach. For this purpose, spatial analysis was performed using the ecological and social spatial data for LUCC tendencies calculated for 1999–2019 and projected for short-term CC scenarios and using LUCC calculated for 2039 in trend-based (TREND) and restrictive (REST) scenarios. The results reveal that increases in the SEV in 2039 will be related to important decreases in the HES; furthermore, the REST scenario suggests decreases in the SEV due to decreases in the HES, assuming that environmental public policy instruments will be preserved in this region. The present work aims to contribute to decision-making for HES preservation at local and regional scales and to help develop adaptation strategies under LUCC and CC scenarios.
