The promise of Indigenous and local knowledge (ILK) for conservation policy depends on how pervasively ILK is held among local people. In the Peruvian Amazon, we conducted a landscape-scale concordance analysis between (1) ILK for game, timber, and fish species collected by the largest representative ILK survey as yet undertaken in tropical forests, and (2) remotely sensed land cover as proxies for species habitat. From our survey among 4000 households in 235 communities, we find that concordant ILK is highly pervasive across gender, age, place of origin, and social status, irrespective of species and people's indigeneity. Resource users possess more concordant knowledge than nonusers for timber and fish, not game. Concordance between ILK for fish and remote sensing is associated with cooperative forest clearing in shifting cultivation-an informal community institution in which forest peoples engage with nature. Our findings point to the promise of ILK for large-scale tropical conservation.

There is broad consensus on the socioeconomic importance of beekeeping and the essential services it provides through pollination. However, beekeeping is being impacted by global environmental changes, and more specific insights are needed. Beekeeping is not a homogeneous activity; it is practiced in various ways and contexts. This study examines how these changes affect beekeeping operations of different sizes in Mediterranean Spain and whether size influences adaptation. Structured interviews were conducted to assess the sector's vulnerability, with climate change identified as a key contributing factor. The findings reveal that the vulnerability of beekeeping is shaped not only by multiple transformations but also by the diverse adaptive capacities of beekeepers. Additionally, the size of beekeeping operations significantly influences this capacity, a factor that should be integrated into policymaking given the sector's highly polarized nature.

Antarctica and the Southern Ocean are key elements in the physical and biological Earth system. Human-induced climate change, and other human activities in the region, are leading to several potential interacting tipping points with major and irreversible consequences. Here, we examine eight potential physical, biological, chemical, and social Antarctic tipping points. These include ice sheets, ocean acidification, ocean circulation, species redistribution, invasive species, permafrost melting, local pollution, and the Antarctic Treaty System. We discuss the nature of each potential tipping point, its control variables, thresholds, timescales, and impacts, and focus on the potential for cumulative and cascading effects as a result of their interactions. The analysis provides substantial evidence of the need for more concerted and rapid action to limit climate change and to minimise the impacts of local human activities to avoid these cascading tipping points.

A global assessment of the status of tertiary, vocational, and technical forest education and training found deficits in inclusion of knowledge and student diversity. Coverage of forest services and cultural and social issues was characterized as weak in the curricula of many programs. The inclusion of traditional and Indigenous knowledge was frequently poor or absent. Gaps were found in enrollment at tertiary education levels with respect to diversity by gender, race/ethnicity, and other societal groups. If unaddressed, forest researchers, professionals, and workers will continue to lack familiarity with different knowledge systems and the importance of inclusive representation. Improvements in forest education related curricula, research, monitoring, policy, recruitment, and promotion are recommended. Without remedial action to build a representative, skilled, and knowledgeable workforce, prospects for forests to meet local, national, and global goals are at risk. Improved social and knowledge diversity in forest education is paramount for the future of forests.

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.

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.
