Now is the time for conservationists to stand up for social justice

Existing power imbalances and injustices could be exacerbated by large flows of international funding for nature recovery. Conservationists are still grappling with what social justice means in practice; a major shift in mindset is required

Managing social-ecological systems under uncertainty: Implementation in the real world

Management decisions for natural resources are not made in a vacuum; the environmental and ecological conditions as well as the socioeconomic and political contexts affect goals, the choice of interventions, their feasibility, and which outcomes are obtained. Although uncertainty is recognized as a feature of natural resource management, little attention has been given to the uncertainty generated by institutional settings, historical contingency, and individual people's influence. These implementation uncertainties, related to the translation of policy into practice, make it difficult to predict the outcomes of management interventions within social-ecological systems. Using the conservation of species hunted for bushmeat in the Serengeti as a case study, we investigated the challenges and potential barriers to successful implementation of natural resource management policies. We used a mixed-methods approach, combining semistructured interviews with scenario building, social network, and institutional analysis exercises. Using a management strategy evaluation (MSE) conceptual framework, we obtained insights into the constraints and opportunities for fulfilling stakeholder aspirations for the social-ecological system, analyzed the multiple roles played by different institutions in the system, and described the interactions between different actor types. We found that the respondents had generally similar views about the current and future status of the Serengeti but disagreed about how to address issues of conservation concern and were more uncertain about the actual outcomes of management interventions. Improving conservation implementation (rather than research, monitoring, or status assessment) was perceived as the key priority to be addressed. Institutional barriers were perceived as an important challenge given that the decision-making and implementation processes were broadly distributed across a number of institutions. Conservation social networks were centered on very few individuals, suggesting their importance in bridging across conservation arenas but also potentially affecting the resilience of governance structures. Our study gives an improved understanding of the underlying causes of discrepancies between conservation plans and outcomes for this case study, as well as providing a novel framework for the analysis of implementation uncertainties more broadly. A next step would be to use this framework as a basis for collaboratively developed models that integrate research findings with specific management questions. By bringing tools and findings from social psychology, natural resource management, and bioeconomics together into a unified operational framework, researchers may be better able to understand the barriers to successful resource management and engage with stakeholders to overcome them

Exploring the human-nature nexus towards effective nature-based solutions: the Aral Sea case

Incorporating societal challenges and values into the design of locally appropriate nature-based solutions (NbS) is an integral strategy for ensuring benefits for both communities and the environment. But how are human-nature relations impacted when the environments containing resources which are valued and relied on, undergo dramatic and sustained change on decadal timescales? To explore this interplay, we selected Muynak as a case study, once a thriving town on the shores of the former Aral Sea in Uzbekistan. We conducted a social survey among the residents to identify the use of natural resources and the values they assign to the most common and yet highly degraded resources in the area (wetlands, rangelands, afforested areas, the Aral Sea, and wildlife). The survey was complemented with expert interviews. Our study suggests that grasslands are the most frequently used of the resources under study, while wetlands and wildlife are generally more valued. Overall, resources were more culturally valued than financially, historically, or recreationally. The majority of respondents perceived a degradation in most natural resources over the past decade, particularly wetlands (79 %), followed by grasslands (48 %), and the Aral Sea (42 %). Wetlands were reported to be in a state of ongoing degradation by 79 % of respondents, which negatively affected the livelihoods of almost half of the households in the survey area. Afforested areas were the only resources reported to have a positive perceived change in both status and their effect on well-being. The vast majority of respondents (83 %) felt that human well-being was linked to environmental conditions. This study lays the foundation for future interventions to develop nature-based solutions to benefit both people and nature, and highlights the continuing value placed on nature by residents of an area that has suffered substantial anthropogenic degradation

Drivers of coral reef marine protected area performance

Coral reefs are severely threatened and a principal strategy for their conservation is marine protected areas (MPAs). However the drivers of MPA performance are complex and there are likely to be trade-offs between different types of performance (e.g. conservation or welfare related outcomes). We compiled a global dataset from expert knowledge for 76 coral reef MPAs in 33 countries and identified a set of performance measures reflecting ecological and socio-economic outcomes, achievement of aims and reduction of threats, using spatial or temporal comparisons wherever possible. We wanted to test the extent to which distinct types of performance occurred simultaneously, understood as win-win outcomes. Although certain performance measures were correlated, most were not, suggesting trade-offs that limit the usefulness of composite performance scores. Hypotheses were generated as to the impact of MPA features, aims, location, management and contextual variables on MPA performance from the literature. A multivariate analysis was used to test hypotheses as to the relative importance of these “drivers” on eight uncorrelated performance measures. The analysis supported some hypotheses (e.g. benefit provision for the local community improved performance), but not others (e.g. higher overall budget and more research activity did not). Factors endogenous to the MPA (such as size of the no-take area) were generally more significant drivers of performance than exogenous ones (such as national GDP). Different types of performance were associated with different drivers, exposing the trade-offs inherent in management decisions. The study suggests that managers are able to influence MPA performance in spite of external threats and could inform adaptive management by providing an approach to test for the effects of MPA features and management actions in different contexts and so to inform decisions for allocation of effort or funds to achieve specific goals

Combining simulation and empirical data to explore the scope for social network interventions in conservation

Conservationists can use social network analysis to improve targeting for behaviour-change interventions, selecting individuals to target who will go on to inform or influence others. However, collecting sociometric data is expensive. Using empirical data from a case study in Cambodia and simulations we examine the conditions under which collecting this data is cost-effective. Our results show that targeting interventions using sociometric data can lead to greater dissemination of information and adoption of new behaviours. However, these approaches are not cost-effective for small interventions implemented in only a few communities, and it is an order of magnitude cheaper to achieve the same results by simply targeting more individuals in each community at random. For interventions across multiple communities, network data from one community could inform rules-of-thumb that can be applied to boost the effectiveness of interventions. In rural Cambodia, this approach is worthwhile if it can inform interventions covering at least 21 villages. Our findings provide a framework for understanding how insights from network sciences, such as targeting clusters of individuals for interventions that aim to change behaviour, can make a practical contribution to conservation

A framework for understanding the contributions of local residents to protected area law enforcement

Terrestrial and marine protected areas have long been championed as an approach to biodiversity conservation. For protected areas to be effective, equitable and inclusive, the involvement of local residents in their management and governance is considered important. Globally, there are many approaches to involving local residents in protected area law enforcement. However, opportunities for comparing different approaches have been limited by the lack of a clear common framework for analysis. To support a more holistic understanding, we present a framework for analysing the contributions of local residents to protected area law enforcement. Informed by a review of the literature and discussions with conservation practitioners, the framework comprises five key dimensions: (1) the different points in the enforcement system at which local residents are involved, (2) the nature of local participation in decision-making, (3) the type of external support provided to local residents, (4) the different motivating forces for participation, and (5) the extent to which local participation is formalized. We apply the framework to three real-world case studies to demonstrate its use in analysing and comparing the characteristics of different approaches. We suggest this framework could be used to examine variation in local participation within the enforcement system, inform evaluation and frame constructive discussions between relevant stakeholders. With the global coverage of protected areas likely to increase, the framework provides a foundation for better understanding the contributions of local residents to protected area law enforcement

Investigating determinants of compliance with wildlife protection laws: bird persecution in Portugal

Conservation interventions are generally underpinned by formal rules. These rules often suffer from high rates of non-compliance which is difficult to investigate due to its clandestine nature. Here we apply socio-psychological approaches to investigate the prevalence and determinants of three illegal bird-threatening behaviours---shooting raptors, trapping passerines for consumption, and poison use---by surveying 146 respondents in Portugal. We apply the theory of planned behaviour to understand behavioural determinants, and an indirect questioning method, the unmatched count technique (UCT), to estimate behaviour prevalence. The UCT estimated a high prevalence of trapping for consumption (47 {\%} SE 15) and shooting raptors (14 {\%} SE 11); both estimates being higher than from direct questioning. Poisoning had a lower prevalence according to direct questioning (7 {\%}), while the UCT generated a negative estimate suggesting that poisoning is a particularly sensitive behaviour. Different demographic groups were associated with different behaviours and determinants; men with greater rule knowledge were more likely to trap birds, while locally born people were less likely to approve themselves, or to think others approved of, trapping. Those with more positive attitudes to poisoning were more likely to admit to it, and these positive attitudes were found more in older non-hunters. Rule knowledge was better in younger male hunters. These findings suggest that NGOs aiming to reduce poisoning could enlist the support of hunters, while locally born people may be more receptive than others to working with NGOs to reduce trapping. These groups may be powerful allies in reducing illegal behaviours in their communities

Improving environmental interventions by understanding information flows

Conservationists are increasingly interested in changing human behaviour. One understudied aspect of such interventions is information flow. Different patterns of interpersonal communication and social structures within communities influence the adoption of behavioural changes through social influence and social reinforcement. Understanding the structure of information flow in a group, using tools such as social network analysis, can therefore offer important insights for interventions. For example, communications may be targeted to highly connected opinion leaders to leverage their influence, or communication may be facilitated between distinct subgroups to promote peer learning. Incorporating these approaches into conservation interventions can promote more effective behaviour change. This review introduces conservation researchers and practitioners to key concepts underpinning information flows for interventions targeting networks of individuals

Incentivizing monitoring and compliance in trophy hunting

Conservation scientists are increasingly focusing on the drivers of human behavior and on the implications of various sources of uncertainty for management decision making. Trophy hunting has been suggested as a conservation tool because it gives economic value to wildlife, but recent examples show that overharvesting is a substantial problem and that data limitations are rife. We use a case study of trophy hunting of an endangered antelope, the mountain nyala (Tragelaphus buxtoni), to explore how uncertainties generated by population monitoring and poaching interact with decision making by 2 key stakeholders: the safari companies and the government. We built a management strategy evaluation model that encompasses the population dynamics of mountain nyala, a monitoring model, and a company decision making model. We investigated scenarios of investment into antipoaching and monitoring by governments and safari companies. Harvest strategy was robust to the uncertainty in the population estimates obtained from monitoring, but poaching had a much stronger effect on quota and sustainability. Hence, reducing poaching is in the interests of companies wishing to increase the profitability of their enterprises, for example by engaging community members as game scouts. There is a threshold level of uncertainty in the population estimates beyond which the year-to-year variation in the trophy quota prevented planning by the safari companies. This suggests a role for government in ensuring that a baseline level of population monitoring is carried out such that this level is not exceeded. Our results illustrate the importance of considering the incentives of multiple stakeholders when designing frameworks for resource use and when designing management frameworks to address the particular sources of uncertainty that affect system sustainability most heavily
