Interdependence of ecological and social systems is widely acknowledged, but consideration of how local communities are influenced by processes at other sectors or scales is often omitted. This research addresses this gap by examining the implementation of China’s national environmental programs (NEPs) to combat desertification. We investigate (a) the changes in local social-ecological systems and the role of the NEPs therein since the year 2000; (b) how the changes have affected local livelihoods and behaviors and attitudes toward the NEPs and the land; and (c) the role of other drivers in the changes and their implications. Interviews and surveys were conducted with scientists, grassroots implementers, and local farmers and herders. Secondary socioeconomic data were used to understand broader changes and drivers. Our results indicate that the NEPs generated both positive and negative biophysical and socioeconomic changes, and that they were both supported and disrupted by institutions at other sectors and scales. Although farmers and herders appreciated an improved environment and living standards, they suffered from other changes, such as reduced arable land area, rising costs of living and production, precarious markets, and extreme weather events. Absence of social security and limited social capital made farmers and herders unable to engage in long-term practices that support land conservation and their well-being. The findings highlight the need to foster systemic resilience in local communities through the provision of social security and social capital building to navigate the changing world.

Residential green spaces in cities can make a significant contribution to urban conservation. To engage urban residents in conservation, we need to understand what influences participation. We interviewed leaders of community conservation groups and surveyed members of the public in Auckland, New Zealand using an anonymous questionnaire. We investigated whether environmental attitudes differ between those who do and do not participate in conservation actions (volunteering in a community conservation group and/or controlling pest mammals), and the motivations and barriers to participating in conservation actions. We found that conservation leaders often founded their conservation groups with a biodiversity motivation, whereas many of their group members subsequently joined and continued to participate for social reasons. Conservation group members were more likely to be in favor of pest control and had more positive environmental attitudes than non-participants. They found group work more motivating and productive than working alone. For people already participating in conservation (controlling pests, leading a group, or volunteering), the most common barrier to increasing participation was opportunity, most notably a lack of time. We found that people tended to control pest mammals for self-interested reasons, such as preventing damage to their homes (67%; n = 358), whilst biodiversity motivations (protecting native species) were secondary (53%; n = 283). For people not participating in pest control, the primary barrier was a lack of interest in participating (26%; n = 109). Although people were supportive of conservation, biodiversity motivations alone are unlikely to be a sufficient motivator for participation. Given the range of different motivations and barriers, targeted messaging (e.g., promoting social connections) could increase participation in urban conservation.

Rapid global change threatens to outstrip global efforts to establish sustainable stewardship of social-ecological systems (SES). Place-based research can enhance effectiveness of global sustainability policies and actions by providing contextualized knowledge underpinning bottom-up solutions. However, the use and transfer of place-based knowledge remains a major challenge. In this study, we analyze place-based knowledge transfer in a local-to-global and knowledge-to-action context. We aim to provide insights on when, how, and why place-based research can inform decision making at the global scale and lead to action toward more sustainable and just futures. Our iterative and exploratory methodology involved alternating rounds of literature reviews and interviews with interdisciplinary researchers. We identified four key steps (place-based knowledge production, knowledge synthesis, knowledge use at the global scale, and knowledge revision and lessons learned) and five facilitative factors (bridging organizations, knowledge brokers, boundary organizations, institutionalized knowledge governance, and polycentric governance systems), which provide a comprehensive understanding of place-based knowledge transfer. Our conceptual framework provides suggestions on how to set up place-based knowledge transfer to be more effective, complete, and inclusive. Furthermore, our study discusses two major structural challenges that currently inhibit place-based knowledge transfer and shows ways forward for science and policy to overcome these. We argue that place-based knowledge transfer can be an effective means to undo dominant power relations and the epistemic status quo and enable a shift from short-termism in science and policy toward more long-term SES goals. Therefore, it is seminal to open up the predominant value system to more diverse knowledge systems, signifying a shift away from global decision making that is guided by neoliberal capitalist principles and over-emphasizes short-term and individual gains. Finally, it is crucial to prioritize learning over knowing to exploit the long-term value of place-based knowledge transfer.

We examined the role of anti-extractivism as environmental peacebuilding through a conflict transformation framework. Environmental peacebuilding aims to foster peace through addressing environmental issues to remedy root causes of conflict; such efforts must further account for and respond to the changing climate. To this end, we explored how community-level movements encounter structural constraints, oppressions, or opportunities. Rather than relying on existing structures as a means to resolve conflict, we suggest that environmental conflict transformation presents an opportunity to foster climate resilient peace responding to differing needs of various groups, extending beyond the absence of war, and responding to the realities of climate change. We conducted case studies with the organizations Casa Pueblo in Puerto Rico and Movimento Bem Viver in Brazil to explore how conflict transformation helps shift environmental peacebuilding toward both being able to respond to destructive patterns and to achieve a more peaceful future through a process of change. We argue that the act of negating extractivism is a positive action toward transformation for peace. We thus contribute theoretical and empirical insight to the study of environmental peacebuilding, broadening ongoing discussions on building climate resilient peace that is beneficial to both humans and the environment.

Although the impacts of shrub encroachment on the ecosystem processes have been well-documented, little is known about the extent to which socio-cultural values and perceptions might influence actions undertaken to manage shrub proliferation. Understanding stakeholder values is important because the ecosystem’s capacity to supply a given service or suite of services must be balanced against the value society places on them. Research to date has emphasized supply with little consideration of value, making it difficult to comprehensively or objectively evaluate trade-offs and set priorities, particularly when managing for one particular service or a suite of services that may adversely affect other services. To address this, we conducted a case study in Southern Arizona and New Mexico (USA) to evaluate stakeholder perceptions of and preferences for various ecosystem services provided on semi-arid rangelands where shrub proliferation has impacted traditional livestock grazing. Perceptions of rangeland ecosystem services were elicited via a visually based landscape interpretation while preferences were quantified using best-worst scaling (BWS). Our findings suggest that stakeholders familiar with rangelands and their management generally perceive low shrub cover as providing a wider range of valued ecosystem services compared to rangelands with high shrub cover. Contrary to expectations, ecosystem service preferences in the context of shrub encroachment were generally uniform across all stakeholder groups (e.g., ranchers, state/federal governmental employees, non-governmental land managers, academicians, recreationists), with habitat for biodiversity and erosion control being identified as the most preferred. Accordingly, our results indicate that the widespread perception/assumption that ranchers in this region undertake brush management to enhance livestock production solely for economic gain is seen as too narrow. Our results also suggest an opportunity for brush management to serve as a potential win-win management action if framed as a way to maintain or promote rangeland biodiversity and mitigate erosion.

Wildfire in California is an increasing threat to life and property. The expansion of urban and suburban development into wildlands limits risk-reduction options like prescribed burning, whereas large-scale mechanical and herbicide treatments can be cost prohibitive and unpalatable to the public. Cattle grazing is a low risk, affordable treatment not frequently considered for use explicitly for fuels reduction in California. To examine the impact of cattle grazing on fire in Napa and Sonoma Counties, California, we quantified its effects as change in average annual burn probability. Probabilities were calculated for 2001–2017 using mixed-effect regression models in combination with a range of grazing intensities and extents. These grazing scenarios were designed to represent current grazing conditions, ungrazed conditions, adding grazing to high priority landscapes, and grazing the full study area. We estimated that under current grazing conditions, cattle grazing reduces average annual burn probability 45% (from 9.9% to 5.4%) compared to ungrazed conditions. Adding grazing to high priority landscapes as identified by the California Department of Forestry and Fire Protection (CAL FIRE) decreased their average annual burn probability by 82% (from 7.6% to 1.4%) compared to under current grazing conditions. Of the scenarios assessed, grazing high priority landscapes heavily while maintaining the current extent and intensity of grazing on other rangelands provided the best return in terms of decreased burn probability per additional area grazed. Finally, we demonstrated how our methodologies can be utilized by fuel managers and planners to identify key areas for treatment with cattle grazing. Our findings suggest cattle grazing provides benefits to the study area by reducing overall burn probability, and that extending its use to treat fuels in priority areas in and around the wildland urban interface could provide further fire-risk reduction on community-adjacent lands. Land managers may find cattle grazing a valuable long term fuel-management tool at the landscape scale.

The food-energy-water (FEW) nexus has been argued as an approach to improve system resilience and sustainability theoretically. However, there is limited empirical understanding of which governance factors lead to FEW nexus collaboration in practice. The purpose of this study is to investigate the conditions associated with FEW nexus collaboration in cities in resilience planning: does it arise from risk of resource insecurity, pre-existing governance mechanisms, or both? The study analyzed the 22 cities in the United States that are part of the Resilient Cities Network using fuzzy-set Qualitative Comparative Analysis. The results show that food, energy, and water insecurity are not sufficient to explain FEW nexus collaboration in resilience planning. However, the results do show that FEW nexus collaboration is present in resilience planning in (a) cities that do experience water insecurity and employ two of three investigated governance conditions—policy coherence, stakeholder participation, or institutional support—or (b) that employ all three governance conditions, regardless of whether or not they experience water insecurity. It concludes that the risk of resource insecurity alone is not sufficient to explain cities’ implementation of FEW nexus collaborations and provides policy recommendations for increased FEW nexus collaboration in practice.

As natural habitats decline and wildlife adapts to increasing anthropogenic disturbance, it is crucial to understand human-wildlife relationships in residential areas. However, relevant studies are limited and mostly focused on single cities. To address this knowledge gap, we investigated people’s preferences for seeing wild mammals in residential areas by conducting and analyzing an online survey distributed across Germany (n = 2997 participants). Our results revealed that preferred species (squirrels, hedgehogs, hares, roe deer) were frequently encountered, whereas unpreferred species were those encountered frequently (rats, martens), as well as those encountered rarely (wild boar, coypus, raccoons). We also found a moderately positive correlation between the number of encounters with mammals and them being preferred by humans. Finally, some socio-demographic variables, particularly gender, garden access, and urbanity, are significantly related to human preferences. Based on our results, we propose tailoring wildlife management in residential areas to promote the positive attributes of preferred wildlife as biodiversity ambassadors, while also addressing ways to mitigate encounters and negative perceptions associated with unpreferred species.

Human-carnivore relations in Europe have varied throughout history. Because of recent conservation efforts and passive rewilding, carnivore populations are recovering, which translates into more interactions with humans. Thus, unraveling these interactions as well as the multiple contributions carnivores provide to people is crucial to their conservation. We examined the literature conducted in Europe since 2000 and used the nature’s contributions to people (NCP) framework to identify factors that have shaped human-carnivore relations. To do so, we examined the state of scientific knowledge and relationships among types of NCP from carnivores, countries, and carnivore species; and between NCP, actors, and management actions. Results indicated that research has been oriented toward large carnivore species and their detrimental contributions to people. Further, the effectiveness of carnivore management strategies has only been evaluated and monitored in a limited set of all the research. To balance any negative views on carnivores, we suggest that the recognition of the duality of carnivores, as providers of both beneficial and detrimental contributions, should be included in EU conservation policies.

The natural capacity of marine sediments to capture, sequester, and store organic carbon has been recognized by researchers and policy makers for its potential to mitigate against climate change. As a result, Marine Spatial Planning (MSP) and Marine Protected Area (MPA) designation processes increasingly aim to protect “blue carbon” stored in marine sediments by reducing anthropogenic activities that disturb the seabed (e.g., bottom trawling). In this research, we engaged with coastal residents around Dundalk Bay, Ireland to explore public perceptions of the presence and management of carbon-storing marine sediments in the context of the multifaceted relationship between communities and the environment. This has not been previously studied in an empirical setting. Given the largely “unknown” character of this source of blue carbon, we theorized that speculation played a key role in sustaining emerging perceptions of the sediments, by creating a link with existing place meanings. We used interviews (n = 12) and a focus group (n = 7). Reflexive thematic analysis of the data showed that local residents associated multiple, overlapping meanings with Dundalk Bay. We found evidence that speculative mechanisms such as analogy and experiential knowledge were used to bridge between existing place meanings and emerging perceptions of carbon-storing marine sediments, which also helped indicate the valence of people’s feelings about the sediments. We found different views about the presence of the sediments, and residents varied in their prioritization of measures to protect either nature or economic activity in the bay. Because of scientific knowledge gaps related to the distribution and character of marine sediments and the impacts of anthropogenic activity, participants stressed the need for further research and a careful approach to the management of the bay and its sediments. Our work reiterates the importance of recognizing existing people–place connections to understand potential responses to changes in the use and/or management of marine environments. This can help achieve a more engaged and socially acceptable MSP process.
