Social and institutional diversity ("diversity" hereafter) are important dimensions in collaborative environmental governance, but lack empirical assessment. In this paper, we examine three aspects of diversity hypothesized in the literature as being important in collaborative forms of environmental governance—the presence of diverse actors, diverse perspectives, and diverse institutions. The presence of these aspects and formative conjectures were empirically considered using a mixed methods approach in four biosphere reserves in Sweden and Canada. We found that the diversity of actors involved and domains of authority varied among cases, that stakeholder perspectives were highly diverse in all cases, and that institutional variety (in terms of strategies, norms, and rules) was evident in all cases, but differed among them. Empirical support from the cases further affirms that diversity contributes to the ability to engage with a broader set of issues and challenges; diversity contributes to novel approaches to solving problems within the governance group; and diversity contributes to the flexibility of the group involved in governance in terms of addressing challenges. One conjecture, that diversity decreases the efficiency of governance in decision-making and responding to issues, was not supported by the data. However, our analysis indicates that there might be a trade-off between diversity and efficiency. The findings highlight differences in the ways in which diversity is conceptualized in the literature and on the ground, emphasizing the pragmatic advantages of actively seeking diversity in terms of competencies and capacities.

Social networks are frequently cited as vital for facilitating successful adaptation and transformation in linked social--ecological systems to overcome pressing resource management challenges. Yet confusion remains over the precise nature of adaptation vs. transformation and the specific social network structures that facilitate these processes. Here, we adopt a network perspective to theorize a continuum of structural capacities in social--ecological systems that set the stage for effective adaptation and transformation. We begin by drawing on the resilience literature and the multilayered action situation to link processes of change in social--ecological systems to decision making across multiple layers of rules underpinning societal organization. We then present a framework that hypothesizes seven specific social--ecological network configurations that lay the structural foundation necessary for facilitating adaptation and transformation, given the type and magnitude of human action required. A key contribution of the framework is explicit consideration of how social networks relate to ecological structures and the particular environmental problem at hand. Of the seven configurations identified, three are linked to capacities conducive to adaptation and three to transformation, and one is hypothesized to be important for facilitating both processes. We discuss how our theoretical framework can be applied in practice by highlighting existing empirical examples from related environmental governance contexts. Further extension of our hypotheses, particularly as more data become available, can ultimately help guide the design of institutional arrangements to be more effective at dealing with change.

Landscape connectivity is considered a priority for ecosystem conservation because it may mitigate the synergistic effects of climate change and habitat loss. Climate change predictions suggest changes in precipitation regimes, which will affect the availability of water resources, with potential consequences for landscape connectivity. The Greater Calakmul Region of the Yucatan Peninsula (Mexico) has experienced a 16% decrease in precipitation over the last 50 years, which we hypothesise has affected water resource connectivity. We used a network model of connectivity, for three large endangered species (Baird’s tapir, white-lipped peccary and jaguar), to assess the effect of drought on waterhole availability and connectivity in a forested landscape inside and adjacent to the Calakmul Biosphere Reserve. We used reported travel distances and home ranges for our species to establish movement distances in our model. Specifically, we compared the effects of 10 drought scenarios on the number of waterholes (nodes) and the subsequent changes in network structure and node importance. Our analysis revealed that drought dramatically influenced spatial structure and potential connectivity of the network. Our results show that waterhole connectivity and suitable habitat (area surrounding waterholes) is lost faster inside than outside the reserve for all three study species, an outcome that may drive them outside the reserve boundaries. These results emphasize the need to assess how the variability in the availability of seasonal water resource may affect the viability of animal populations under current climate change inside and outside protected areas.

The group aims at devising sustainable solutions to environmental problems and emphasize benefits from local to global scales.

Social–ecological networks (SENs) represent the complex relationships between ecological and social systems and are a useful tool for analyzing and managing ecosystem services. However, mainstreaming the application of SENs in ecosystem service research has been hindered by a lack of clarity about how to match research questions to ecosystem service conceptualizations in SEN (i.e., as nodes, links, attributes, or emergent properties). Building from different disciplines, we propose a typology to represent ecosystem service in SENs and identify opportunities and challenges of using SENs in ecosystem service research. Our typology provides guidance for this growing field to improve research design and increase the breadth of questions that can be addressed with SEN to understand human–nature interdependencies in a changing world. Social–ecological networks (SENs) provide a promising approach to represent the complex ecological, social, and social–ecological relationships that influence ecosystems service supply. Ecosystem services can be represented in SENs as nodes, links, attributes, or as emergent properties of the network, each bringing distinct aspects of ecosystem services into focus to address different questions. Applications of SENs in ecosystem service research can foster: (i) understanding of the social and ecological drivers of ecosystem services; (ii) forecasting of the impacts of stressors; (iii) investigation of trade-offs between ecosystem services; and (iv) assessment of the effects of alternative management options. Ecosystem service research would benefit from a typology to conceptualize particular ecosystem services in SEN analyses and from greater clarity of when ecosystem service research can benefit from a SEN approach.

This paper examines relationships among perceived processes and outcomes in four UNESCO biosphere reserves (BRs). BRs offer a unique opportunity to examine these relationships because they aim to foster more adaptive and collaborative forms of management, i.e. adaptive co-management (ACM). Accounting for the outcomes of ACM is a difficult task and little progress has been made to this end. However, we show here that ACM efforts in all four BRs had a myriad of positive results as well as ecological and livelihood effects. Process variables of collaboration and learning explained over half (54.6%) of the variability in results and over one third (35.1%) of the variability in effects. While the overall models for outcomes and subsequent process were not significant, the regressions revealed predictive potential for both process variables. Our analysis highlights that a better process is associated with more positive outcomes and that collaboration and learning make unique contributions to outcomes. Opportunities for quantitative techniques to be utilized in understanding the dynamics of ACM are illustrated. Understanding relationships between process and outcomes (and vice versa) provides a sound basis to answer critiques, enhances accountability, and maximizes the potential of positive impacts for ecosystems and humans.
