Incorporating climate change into conservation and restoration decisions is increasingly important for natural resource managers and restoration practitioners to effectively address the underlying drivers of ecosystem change. Small dam removal is an example of a restoration tool that may offer multiple socioeconomic and ecological benefits in streams, including promoting climate resilience. With the pace of dam removals increasing, practitioners and researchers are well-poised to incorporate climate change into future dam removal decisions. Therefore, we surveyed dam removal practitioners across 14 states in the eastern United States to understand current practices of small dam removals, factors driving restoration decisions, and how climate change knowledge is incorporated into these decisions. We also aimed to identify barriers to and opportunities for knowledge exchange between practitioners and researchers. Of the 100 respondents, most (79%) consider climate change in their dam removal decisions to some extent. Despite this, many reported a lack of clear, relevant, and accessible data linking small dam removal to climate resilience benefits. Dam removal practitioners also indicated that they most often rely on climate change information garnered from conversations with colleagues, rather than from scientific research products. These results suggest that the co-production of relevant, salient research questions and readily accessible and interpretable research products (e.g., technical summaries, open access articles) may encourage practitioners to incorporate climate change science more consistently and efficiently into dam removal decisions. These findings may also translate to other stream restoration efforts to inform knowledge exchange and improve restoration outcomes in a changing climate.

Innovative conservation approaches are urgently needed to balance biodiversity conservation with human development. Safeguarding elephant populations often involves active management, leading to direct intentional, direct unintentional, and indirect consequences for animals, people, and ecosystems. Drawing from One Health and One Welfare principles, our study introduces a multicriteria framework for developing conservation strategies that enhance well-being across dimensions. This approach establishes priorities, acceptability zones, and One Well-being scores that guide decision making toward optimal outcomes. We applied our One Well-being framework to evaluate 12 elephant management interventions currently or historically used in South Africa. Examining data from 3306 instances of these interventions, including on-the-ground data, we assessed their relative impact on environmental, human, and animal well-being. Our analysis identified 250 consequences of these interventions, categorized as 58 direct intentional, 127 direct unintentional, and 65 indirect. Although most direct intentional consequences were beneficial (93.4%), the direct unintentional and indirect consequences were predominantly harmful (96.9% and 75.4%, respectively). Although most interventions improved environmental well-being, their consequences for animal and human well-being were less positive. This highlights a conflict among the three well-being dimensions, underscoring the importance of incorporating human and animal well-being into elephant management strategies. Recognizing the interconnected nature of these dimensions and aiming for multiple, mutually reinforcing gains is imperative. This iterative process helps address social-ecological vulnerabilities and risks while advocating for ethical conservation practices, fostering multidisciplinary collaboration, and garnering broader support for conservation efforts. Our approach aligns with global goals for sustainable and equitable wildlife management outcomes.

Marine protected areas (MPAs) are widely promoted as effective tools for conserving biodiversity and safeguarding ecosystem services. However, MPA success can be hindered by a lack of legitimacy and low social support because of perceived negative effects on ecosystem services and human well-being. Despite these social challenges, the social dimensions of marine conservation, such as the effects of MPAs on coastal livelihoods and local communities’ perceptions of these effects, are often overlooked in conservation initiatives. In this study, we use a mixed methods approach, combining qualitative thematic analysis and quantitative network analysis derived from interviews and focus group discussions, to examine the perceptions of key stakeholder groups about the Litoral Norte MPA in Portugal. Our findings reveal that most stakeholder groups hold more negative than positive views about the governance and management of the MPA. Key concerns include unsatisfactory participation in MPA decisions and perceptions that the MPA fails to deliver positive social and ecological outcomes, such as increased community involvement, fair income distribution, and enhanced fish abundance. Policy makers and managers need to address these negative perceptions to improve conservation governance and management. By considering the stakeholder feedback presented in this study, such as fostering better engagement with the local community and transforming conflicts into opportunities for co-developing new conservation actions with local resource users, policy makers and managers can increase support for Litoral Norte and enhance the social and ecological outcomes of the MPA.

Although forest devolution, as a type of decentralization, is a high priority in the policy agendas of developing countries, recentralization has also occurred. In this paper, we focus on emerging recentralization within the devolution process of Collective Forest Tenure Reform (CFTR) in China’s southern provinces and conceptualize this process as “recentralized forest devolution.” In this paper, we update a key framework for analyzing decentralization and recentralization in governance processes based on the “policy arrangement approach.” Case studies were conducted in four counties of the Fujian and Yunnan provinces by tracing governance dynamics from 2001 to 2019. Our study found that the central government has tightened upward accountability and recentralized power for environmental conservation since 2012 under the discourse of “Ecological Civilization.” At the local level, recentralized forest devolution was expressed in terms of the restricted timber harvest levels for the purposes of environmental conservation. Therefore, forest devolution could be more vulnerable than expected by researchers and potentially interwoven with recentralization processes. Discourses, actors, property rights, and power are, therefore, considered to be interwoven in the complex dynamics of decentralization and recentralization.

Ecologists often leverage contributory science, also referred to as citizen science, to answer large-scale spatial and temporal biodiversity questions. Contributory science platforms, such as eBird and iNaturalist, provide researchers with incredibly fine-scale data to track biodiversity. However, data generated by these platforms are spatially biased. Research has shown that factors like income, race, and historical redlining can influence spatial patterns of reported eBird and iNaturalist data. However, the role of contemporary residential segregation remains unclear. Additionally, we do not understand how these variables potentially relate to certain Census tracts having more or less biodiversity data than you would expect based on size or population density. To further understand the social factors that may contribute to spatial biases in eBird and iNaturalist data, we focused on three cities within the USA (Oakland, California; St. Louis, Missouri; and Baltimore, Maryland). We specifically investigated how income, race, segregation, and redlining via Home Owners’ Loan Corporation grades (grades A = best, B, C, and D = hazardous and “redlined”) are associated with the difference between reported and expected observations based on area and human population density. We find that census tracts with higher income and more White people generally have more observations than expected. We only find segregation to influence differences in reported and expected observations in Baltimore, with more segregated Census tracts having more observations than expected. Lastly, we find that grades C and D consistently have fewer data than expected compared with grades A and B for both platforms in each city. Our results show that although each city has distinct societal and ecological features, societal inequity permeates each city to shape the uptake of data for two of the largest sources of biodiversity data.

Armed conflicts can lead to environmental degradation, thereby threatening the basis of people’s livelihoods and well-being. Identifying areas where conflicts drive environmental degradation is important for designing effective recovery strategies, but this is inherently challenging in insecure contexts. We use a case study in Tigray, Ethiopia to illustrate how open-source satellite data can be used to support the identification of woody vegetation loss during armed conflicts in situations where ground-based assessments are difficult or impossible. Areas of potential woody vegetation loss extend across 930 km² (approximately 4% of the area occupied by forest and other woody vegetation in Tigray) and appear to be concentrated mostly along major roads; however, vegetation recovery has continued during the war across a significantly larger area (approximately 2600 km²). Spatial patterns of woody vegetation loss appear to be unrelated to drought conditions and large-scale wildfires. Based on these observations and anecdotal evidence of deforestation, we propose that it may be conflict-driven deforestation, caused by increases in fuel wood demands, that are driving the woody vegetation losses in some areas of Tigray. Eventual recovery efforts will have to consider the loss in landscape health during the war in areas where woody vegetation has declined, and include efforts to restore this vegetation to ensure both food security and livelihoods. Open access satellite data, together with ground-based data collection, could inform such post-war restoration efforts by helping identify degraded areas at a regional scale.

Although the impacts of climate change are increasingly challenging food production efforts around the globe, evidence from past studies suggests that adapting and building food systems’ resilience to climate change is not a trivial task. In this study, we adopted a multi-stakeholder perspective by using qualitative and quantitative data to examine the process of building resilience in food value chains against droughts. Through a transdisciplinary process engaging practitioners from different activities of four key Swiss food value chains, we identified measures to build resilience in these value chains and their respective barriers, and determined key stakeholders to facilitate the implementation of the measures. We further complemented the results of the study with a quantitative survey of 832 Swiss farmers aimed at more deeply understanding the barriers from an agricultural perspective. The measures proposed by the practitioners for building resilience in the value chains are primarily focused on production activity and are aimed at avoiding production disruptions and mitigating farmers’ economic losses. Although some of these measures (e.g., irrigation, amassing stocks of animal feed) can be implemented by farmers themselves, other measures (e.g., compensation through pricing changes, flexibility in quality requirements) require interventions from other stakeholders, including post-production actors (processors, retailers) and consumers. However, our results indicate that such implementation is hindered by conflicting interests, the uneven exposure of actors to droughts, and a lack of motivation by the actors to act beyond securing their own operational needs. We conclude that a value chain approach based on collaboration is essential for building food system resilience against droughts and that research on motivations to enable such collaborations deserves more attention in resilience design and research.

The practice of ecological restoration through native plant gardening is emerging among community groups as a means of addressing degradation in urban landscapes. Despite this trend, restoration remains primarily studied as a professional practice. Grassroots associations support people in growing native plants, but within the research on restoration ecology, there remains little study of how non-professionals engage in the practice. We adapt and expand Ivan Illich’s concept of a convivial community tool (i.e., a tool that is open and accessible rather than restricted to certain users) to ecological restoration through a case study of the Ottawa Wildflower Seed Library. Participants highlighted two main strategies of the seed library: overcoming barriers and supporting emergent practices. The seed library helped people overcome the barriers of plant availability, cost, and knowledge, while supporting spontaneous initiatives from volunteers to further the mission of the seed library. We argue that these two strategies operationalize the idea of a convivial community tool. This research contributes an understanding of one way that ecological restoration can broaden its appeal by empowering non-professionals to engage in restoration and provides a starting point for a novel organizational framework based on Illich’s ideas.

Global literature recognizes the interactions between endogenous and exogenous forest resource (FR) management institutions. However, a comprehensive understanding of the sources, mechanisms, and outcomes of institutional change in diverse physiographic regions is lacking. We analyzed mechanisms and outcomes of five decades of institutional change across four physiographic regions of Nepal. Data collection involved 45 key informant interviews, 37 expert interviews, and 22 focus group discussions, complemented by a review of 24 policy documents and 8 community forest (CF) management plans and reports. Through directed content analysis, we found that endogenous institutions are rooted more in customs, traditions, and social hierarchies, and formal exogenous institutions are rooted in national and international policies, which are frequently observed for commercialized forest resources. It further revealed transformational changes in forest management institutions from state-oriented to community-based management across the regions between 1976 and 2010. Critical juncture, priming-framing and puzzling-learning were key mechanisms in the middle and high mountains. In contrast, Terai’s recurrent mechanisms were negative/positive feedback and patching-up. After 2010, (de)incremental changes linked to exogenous and endogenous institutions were found to align more with a global agenda (e.g., REDD+). Priming-framing, negative/positive feedback, and transposition were key institutional change mechanisms of exogenous institutions across the study sites. Economic growth and exogenous institutions played an important role in (de)incremental changes linked to endogenous institutions. Additionally, exogenous institutions produced mixed socioeconomic and positive ecological outcomes, showing regional variations. Endogenous institutions led to positive outcomes, highlighting their importance in sustainable forest management. Future research should examine power dynamics, shedding light on how local actors employ institutions and power to produce differential outcomes in CF.

Earth Stewardship is a transformative initiative that emphasizes the crucial interdependence between human societies and the intricate ecological systems that sustain all life on our planet. Recognizing geodiversity, a concept encompassing the geological and geomorphological characteristics of the Earth’s surface, as an integral dimension of Earth Stewardship, this review highlights its scientific underrepresentation, particularly in East Africa. Geodiversity is pivotal for the integrity of ecological systems, emphasizing its significance as an essential component. By focusing on the Western Rift Valley Corridor (WRVC) within East Africa and its connection to the broader East African Rift System (EARS), we aim to shed light on the significance of geodiversity and its integration with ecological systems in the context of Earth Stewardship. We identify 20 “heritage nodes,” areas of significant geological and ecological value, within the WRVC and demonstrate how geological processes have shaped the region’s landscape. The paper emphasizes the significance of the WRVC as a vital component of the Africa Alive Corridors (AAC) project, which promotes sustainable development in Africa by fostering connections between earth sciences and the humanities. It argues that a transdisciplinary approach involving local communities and stakeholders is essential for the conservation and development of the WRVC and other similar heritage corridors in Africa. The study concludes that geodiversity is a crucial pillar of heritage that enhances our understanding of ecosystems and contributes to sustainability efforts through Earth Stewardship. This research provides a basis for future work within the AAC initiative and the development of ecosystem services among researchers and local stakeholders.
