A bridge over sustainable water: Politicians' perceptions about the preconditions for collective action

Sustainable water resource management is a core interest for all societies. As water systems are often common resources, the management of water systems requires coordinated action among actors along the water. For flowing water, a complication for coordination is upstream-downstream relations where what happens upstream affects downstream, but not the other way around. In this study we present results from a survey experiment with politicians in Sweden, focusing on whether and to what extent their willingness to cooperate is affected by their placement upstream or downstream along a fictive water system. Our findings indicate that politicians from upstream and downstream municipalities share the view that upstream politicians bear greater responsibility for undertaking preventive actions and are willing to assume remedial responsibility for problems caused by them. These results challenge the notion that self-interest is the primary obstacle to resolving environmental collective action problems.

Identifying American climate change free riders and motivating sustainable behavior

Free riders, who benefit from collective efforts to mitigate climate change but do not actively contribute, play a key role in shaping behavioral climate action. Using a sample of 2096 registered American voters, we explore the discrepancy between two groups of free riders: cynics, who recognize the significance of environmental issues but do not adopt sustainable behaviors, and doubters, who neither recognize the significance nor engage in such actions. Through statistical analyses, we show these two groups are different. Doubters are predominantly male, younger, with lower income and education, exhibit stronger conspiracy beliefs, lower altruism, and limited environmental knowledge, are more likely to have voted for Trump and lean towards conservative ideology. Cynics are younger, religious, higher in socioeconomic status, environmentally informed, liberal-leaning, and less likely to support Trump. Our research provides insights on who could be most effectively persuaded to make climate-sensitive lifestyle changes and provides recommendations to prompt involvement in individual sustainability behaviors. Our findings suggest that for doubters, incentivizing sustainability through positive incentives, such as financial rewards, may be particularly effective. Conversely, for cynics, we argue that engaging them in more community-driven and social influence initiatives could effectively translate their passive beliefs into active participation.

Challenges and prospects of transboundary river water conservation and watershed protection in Ethiopia: The case of the upper Blue Nile

This article aims to present the challenges and prospects of transboundary river water conservation and watershed protection in the Upper Blue Nile basin. The River Nile Basin embraces eleven countries shaping their diverse environments and playing a vital role in the livelihoods of its inhabitants. Within this context sharing and managing the River Nile water resources has been a persistent challenge and a potential source of conflict. The Blue Nile River is shared by Ethiopia, Sudan and Egypt and for the latter it is the life artery as the majority of the water reaching Egypt comes from the Blue Nile. Only Egypt and Sudan have an agreement to share the water and there is a need to revisit this mode of resource use based on water allocation among the River Nile countries and especially for the Blue Nile. Nevertheless, these issues have not been resolved and have exacerbated by the commencement and near operation of the GERD. Another important aspect dealt with in this article is the conservation and watershed protection. The study used a qualitative research approach, and data were collected through key informant interviews. Different relevant secondary sources are also consulted. The data were analyzed based on a thematic analysis approach. The key finding of this study was that, despite the Ethiopian unilateral intervention inadequacy to deal with the problem of environmental degradation and water conservation in the Blue Nile Basin neither Ethiopia nor regional institutions like ENTRO attempted to shed light on the impacts of this problem if remained unaddressed. Moreover, Ethiopia and regional actors are void of designing a clear road map to overcome the cloud of mistrust and struggle to dominate the Nile water use which undermined hope for joint action against the common problem that jeopardize the interests of all the basin states. On the other hand the Ethiopian effort to safeguard the shared Nile water resource in the Blue Nile basin yield modest results it may encourage the basin countries to cooperate over the use and management of the Nile water. Hence, the inadequacy of Ethiopia's sole effort to conserve and protect the Upper Nile watershed calls for Ethiopian water management policy and water diplomacy to push for the collaboration of the downstream states as the threats to the Nile water supply are common threats to all Nile basin states' national water security.

The shirker's dilemma and the prospect of cooperation in large groups

Cooperation usually becomes harder to sustain as groups become larger because incentives to shirk increase with the number of potential contributors to collective action. But is this always the case? Here we study a binary-action cooperative dilemma where a public good is provided as long as not more than a given number of players shirk from a costly cooperative task. We find that at the stable polymorphic equilibrium, which exists when the cost of cooperation is low enough, the probability of cooperating increases with group size and reaches a limit of one when the group size tends to infinity. Nevertheless, increasing the group size may increase or decrease the probability that the public good is provided at such an equilibrium, depending on the cost value. We also prove that the expected payoff to individuals at the stable polymorphic equilibrium (i.e., their fitness) decreases with group size. For low enough costs of cooperation, both the probability of provision of the public good and the expected payoff converge to positive values in the limit of large group sizes. However, we also find that the basin of attraction of the stable polymorphic equilibrium is a decreasing function of group size and shrinks to zero in the limit of very large groups. Overall, we demonstrate non-trivial comparative statics with respect to group size in an otherwise simple collective action problem.

A social-ecological systems approach to tick bite and tick-borne disease risk management: Exploring collective action in the Occitanie region in southern France

Ticks are amongst the most important zoonotic disease vectors affecting human and animal health worldwide. Tick-borne diseases (TBDs) are rapidly expanding geographically and in incidence, most notably in temperate regions of Europe where ticks are considered the principal zoonotic vector of Public Health relevance, as well as a major health and economic preoccupation in agriculture and equine industries. Tick-borne pathogen (TBP) transmission is contingent on complex, interlinked vector-pathogen-host dynamics, environmental and ecological conditions and human behavior. Tackling TBD therefore requires a better understanding of the interconnected social and ecological variables (i.e., the social-ecological system) that favor disease (re)-emergence. The One Health paradigm recognizes the interdependence of human, animal and environmental health and proposes an integrated approach to manage TBD. However, One Health interventions are limited by significant gaps in our understanding of the complex, systemic nature of TBD risk, in addition to a lack of effective, universally accepted and environmentally conscious tick control measures. Today individual prevention gestures are the most effective strategy to manage TBDs in humans and animals, making local communities important actors in TBD detection, prevention and management. Yet, how they engage and collaborate within a multi-actor TBD network has not yet been explored. Here, we argue that transdisciplinary collaborations that go beyond research, political and medical stakeholders, and extend to local community actors can aid in identifying relevant social-ecological risk indicators key for informing multi-level TBD detection, prevention and management measures. This article proposes a transdisciplinary social-ecological systems framework, based on participatory research approaches, to better understand the necessary conditions for local actor engagement to improve TBD risk. We conclude with perspectives for implementing this methodological framework in a case study in the south of France (Occitanie region), where multi-actor collaborations are mobilized to stimulate multi-actor collective action and identify relevant social-ecological indicators of TBD risk.

Collective action mitigates the negative effects of COVID-19 threat and anti-abortion restrictions on mental health

BACKGROUND

The COVID-19 pandemic changed our lives in many different domains, forcing people to adapt to countrywide lockdowns, school shutdowns, and business closures. The burden of the COVID-19 pandemic resulted also in deterioration of mental health. At the same time, political conflicts and social inequalities was reinforced and many people engaged in demonstrations to fight for their rights. This study examines whether collective acting for an important cause during the pandemic might mitigate the impact of both political tension related to anti-abortion restrictions and COVID-19 threats on mental health.

METHODS

We conducted a two-wave study with a representative sample of the Polish population, investigating the effect of participating in Polish pro-choice demonstrations on depressive and anxiety symptoms.

RESULTS

Participating in protests attenuated the negative effects of COVID-19 threat and anti-abortion restrictions on mental health. Moreover, we found that the feeling of solidarity with other demonstrators and sense of agency derived from such demonstrations led to lower levels of depressive and anxiety symptoms.

CONCLUSION

The results of the study indicate that participating in meaningful and value-oriented collective action may serve as a buffer against the detrimental effects of social and health threats.

Inducing collective action intentions for healthcare reform through medical crowdfunding framing

As a response to the shortcomings of the U.S. healthcare system, Americans are increasingly turning to crowdfunding platforms to bankroll their health-related costs. However, although medical crowdfunding has rapidly become institutionalized as part of the U.S. healthcare financing landscape, empirical evidence on how Americans perceive its role in healthcare and the impact it might have on public attitudes is scarce. To shed more light on the above, we analyze data from one correlational and one experimental study conducted over September-November 2021. Our correlational study reveals that political orientation is associated with Americans' views on medical crowdfunding. Specifically, we find that those who self-identified as conservative perceived medical crowdfunding as a valid part of the system, and more positively than a universal healthcare system. In contrast, medical crowdfunding is perceived less positively, as hindering a system of universal and affordable healthcare by those more liberally-oriented. In our experimental study, we explore how medical crowdfunding narratives can induce social attitudes conducive to change. Specifically, we test the effect of politicized narratives (vs. control) on group efficacy and subsequently on collective action intentions for healthcare reform, as a function of political orientation. Our results show that politicized narratives might induce collective action intentions through higher group efficacy, but only among those who self-identified as conservative. Liberally-oriented individuals held high collective action intentions for healthcare reform and were not affected by the manipulation. Our work is the first to establish empirically that medical crowdfunding, when employing politicized narratives, can induce collective action intentions, but this effect is moderated by political ideology.

Sustainability, Collective Self-Regulation, and Human-Nature Interdependence

Like any organism, humanity constructs its niche and adapts to the rest of nature by modifying available materials around them. In the era that some have dubbed the "Anthropocene," human niche construction has gone so far as to threaten the planetary climate system. The central question of sustainability is how humanity can collectively self-regulate niche construction, that is, humanity's relationship with the rest of nature. In this article, we argue that to resolve the collective self-regulation problem for sustainability, sufficiently accurate and relevant aspects of causal knowledge about the functioning of complex social-ecological systems need to be cognized, communicated, and collectively shared. More specifically, causal knowledge about human-nature interdependence-how humans interact with each other and the rest of nature-is critical for coordinating cognitive agents' thoughts, feelings, and actions for the greater good without falling into the trap of free riding. Here, we will develop a theoretical framework to consider the role of causal knowledge about human-nature interdependence in collective self-regulation for sustainability, review the relevant empirical research primarily focusing on climate change, and take stock of what is currently known and what we need to investigate in the future.

Valuing adaptive programming: A study of resilience processes and outcomes

Recent decades have seen a growth in theoretical frameworks focusing on systems, context and the dynamic interplay of multiple variables, stimulating interest in complementary research and programme evaluation methods. With resilience theory now emphasising the complex and dynamic nature of resilience capacities, processes and outcomes, resilience programming stands to benefit from approaches such as design-based research and realist research/evaluation. The aim of this collaborative (researcher/practitioner) study was to explore how such benefits can be achieved when programme theory spans individual, community and institutional outcomes, with a focus on the reciprocal processes involved in effecting change across the social system. The context of the research was a regional (Middle East and North Africa) project operating in contexts with an escalated risk of marginalised young people being drawn into illegal/harmful activity. The project's youth engagement and development approach combined participatory learning, skills training, and collective social action, adapted for diverse localities and during the COVID-19 crisis. Quantitative measures of individual and collective resilience were at the centre of a set of realist analyses evidencing systemic connections in changes to individual, collective and community resilience. Findings demonstrated the value, challenges and limitations of the applied research approach for adaptive, contextualised programming.

Thinking Like an Earthling: Children's Reasoning About Individual and Collective Action Related to Environmental Sustainability

Learning to accept and understand our identity as inhabitants of planet Earth is an essential aspect of living sustainably in a global community with others. What is involved in learning, that despite what divides us, we are first and foremost Earthlings and that the well-being of our planetary home is in our collective hands? What are the cognitive features of concepts that are inherent to thinking like an Earthling? This article considers themes that arise from research that inform what is involved in developing a collective, planetary perspective as it relates to engaging in environmental sustainability. It samples research on how young people understand and reason about agency-their own and that of others-and about the relationship between individual and collective action. It considers the importance of recognizing and engaging with diverse perspectives on agency and collectivity as well as being able to adopt the perspectives of those in different roles and positions. While many of the concepts that are inherent to thinking as part of a collective community of Earthlings are challenging, many are also learnable and represent important instructional targets for helping the next generation to understand how to live together in sustainable ways on a small and finite planet.

The vegan dilemma: Do peaceful protests worsen attitudes to veganism?

A body of research has shown that violent protests reduce support for social movements. However, few studies have examined whether the same is true for protests which are peaceful, yet disruptive (e.g., blocking traffic). Across two pre-registered experimental studies, we explored whether pro-vegan protests that are depicted as causing social disruption lead to more negative attitudes towards veganism, compared to non-disruptive protests or a control condition. Study 1 utilised a combined sample of Australian and United Kingdom residents (N = 449; M_age = 24.7 years). Study 2 employed a larger sample of undergraduate Australian students (N = 934; M_age = 19.8 years). In Study 1, disruptive protests were associated with more negative attitudes towards vegans, but only among women. In Study 2, no such effect was found. Instead, a significant main effect was found for the protest's cause (vegan vs. fast fashion), but not protest type (disruptive vs. non-disruptive). That is, reading about a vegan protest, irrespective of how disruptive it was, led to worse attitudes towards vegans, and greater defense of meat consumption (i.e., endorsement of meat eating as natural, necessary, and normal), than reading about a control protest. This effect was mediated by the perceived immorality of the protestors, and, in turn, reduced identification with them. Taking together both studies, the purported location of the protest (i.e., domestic vs. overseas) did not significantly impact attitudes toward the protestors. The current findings suggest that depictions of vegan protests elicit worse attitudes toward this movement, regardless of how peaceful that protest may be. Future research is needed to examine whether other forms of advocacy can ameliorate negative reactions to vegan activism.

Fostering collective action through participation in natural resource and environmental management: An integrative and interpretative narrative review using the IAD, NAS and SES frameworks

Solving humanity's social-environmental challenges calls for collective action by relevant actors. Hence, involving these actors in the policy process has been deemed both necessary and promising. But how and to what extent can participatory policy interventions (PIs) foster collective action for sustainable environmental and natural resource management? Lab and lab-in-the-field experiments on co-operation in the context of collective action challenges (i.e. social dilemmas) and case study research on participatory processes both offer insights into this question but have hitherto mainly remained unconnected. This article reviews insights from these two streams of literature in tandem, synthesising and analysing them using the institutional analysis and development (IAD) framework in combination with the network of action situations (NAS) framework and the social-ecological systems (SES) framework. We thus perform an integrative and interpretative narrative review to draw a richer and more nuanced picture of PIs: their potential impacts, their (institutional and behavioural) mechanisms and challenges, and caveats and recommendations for their design and implementation. Our review shows that PIs can indeed foster collective action by (a) helping the relevant actors craft suitable and legitimate institutional arrangements and (b) addressing and/or influencing actors' attributes of relevance to collective action, namely their individual and shared understandings, beliefs and preferences. To fulfil this potential, the organisers and sponsors of PIs must address and link to the broader context through soundly designed and implemented processes. Complementary follow-up, enforcement and conflict resolution mechanisms are necessary to nurture, reassure and sustain understandings, beliefs and preferences that undergird trust-building and collective action. The conceptual framework developed for the review can help researchers and practitioners further assess these insights, disentangle PIs' mechanisms and impacts, and integrate the research and practice of participatory governance and collective action.

Is Online Moral Outrage Outrageous? Rethinking the Indignation Machine

Moral outrage is often characterized as a corrosive emotion, but it can also inspire collective action. In this article we aim to deepen our understanding of the dual nature of online moral outrage which divides people and contributes to inclusivist moral reform. We argue that the specifics of violating different types of moral norms will influence the effects of moral outrage: moral outrage against violating harm-based norms is less antagonistic than moral outrage against violating loyalty and purity/identity norms. We identify which features of social media platforms shape our moral lives. Connectivity, omniculturalism, online exposure, increased group identification and fostering what we call "expressionist experiences", all change how moral outrage is expressed in the digital realm. Finally, we propose changing the design of social media platforms and raise the issue of moral disillusion when ample moral protest in the online environment does not have the expected effects on the offline world.

Exploring Models for an International Legal Agreement on the Global Antimicrobial Commons: Lessons from Climate Agreements

An international legal agreement governing the global antimicrobial commons would represent the strongest commitment mechanism for achieving collective action on antimicrobial resistance (AMR). Since AMR has important similarities to climate change-both are common pool resource challenges that require massive, long-term political commitments-the first article in this special issue draws lessons from various climate agreements that could be applicable for developing a grand bargain on AMR. We consider the similarities and differences between the Paris Climate Agreement and current governance structures for AMR, and identify the merits and challenges associated with different international forums for developing a long-term international agreement on AMR. To be effective, fair, and feasible, an enduring legal agreement on AMR will require a combination of universal, differentiated, and individualized requirements, nationally determined contributions that are regularly reviewed and ratcheted up in level of ambition, a regular independent scientific stocktake to support evidence informed policymaking, and a concrete global goal to rally support.

Testing the Social Function of Metacognition for Common-Pool Resource Use

Metacognition, the ability to monitor and evaluate our own cognitive processes, confers advantages to individuals and their own judgment. A more recent hypothesis, however, states that explicit metacognition may also enhance the collective judgment of groups, and may enhance human collaboration and coordination. Here, we investigate this social function hypothesis of metacognition with arguably one of the oldest collaboration problems humans face, common-pool resource use. Using an agent-based model that simulates repeated group interactions and the forming of collective judgments about resource extraction, we show that (1) in "kind" environments (where confidence and judgment accuracy correlate positively), explicit metacognition may allow groups to reach more accurate judgments compared to groups exchanging object-level information only; while (2) in "wicked" environments (where confidence and judgment accuracy correlate negatively), explicit metacognition may protect groups from the large judgment errors yielded by groups using metacognitive information for individual-level learning only (implicit metacognition). With explicit metacognition, this research highlights a novel mechanism which, among others, provides a testable explanation of the often-observed finding that groups all over the world communicate to enhance common property use.

On the architecture of collaboration in inter-organizational natural resource management networks

This paper reviews the architecture of collaboration that exists within inter-organizational natural resource management (NRM) networks. It presents an integrative conceptual framework designed to help operationalize the multi-level interactions that occur between different dimensions of trust, risk perception, and control as key concepts in inter-organizational collaboration. The objective is to identify and justify a series of propositions considered suitable for assessing inter-organizational NRM network collaboration through empirical work. Such an integrative conceptualization goes beyond the existing trust scholarship related to collaborative NRM, and, we argue, offers a useful starting point for further exploring some of the 'inner' social dynamics affecting collaborative performance using complex systems thinking. To help establish the relevance of the conceptual framework to transboundary resource governance, a survey operationalizing different dimensions of trust, perceived risk, and control is piloted in the Salish Sea, an ecosystem that spans the Canada-US border between British Columbia and Washington State. Key challenges associated with operationalizing the framework and future research needs are identified.

Collective nostalgia as a balm for the distressed social identity

Group history provides the experiential building blocks that shape social identity. When contemporary events are perceived as having created (or creating) a discontinuity with that history, collective nostalgia is likely to be elicited. Importantly, collective nostalgia is functional-it consolidates social identity, motivating group members to support a return to the group's "true" state of existence. However, no group is a monolith. Factions within a group may have differing opinions on what aspects of the past best represent core features of the ingroup. Variations in the content of the collective nostalgia can cleavage members' responses. Herein, we review research demonstrating the powerful role collective nostalgia and its contents play in intra- and intergroup relations, especially in the socio-political domain.

Leveraging collective action and environmental literacy to address complex sustainability challenges

Developing and enhancing societal capacity to understand, debate elements of, and take actionable steps toward a sustainable future at a scale beyond the individual are critical when addressing sustainability challenges such as climate change, resource scarcity, biodiversity loss, and zoonotic disease. Although mounting evidence exists for how to facilitate individual action to address sustainability challenges, there is less understanding of how to foster collective action in this realm. To support research and practice promoting collective action to address sustainability issues, we define the term "collective environmental literacy" by delineating four key potent aspects: scale, dynamic processes, shared resources, and synergy. Building on existing collective constructs and thought, we highlight areas where researchers, practitioners, and policymakers can support individuals and communities as they come together to identify, develop, and implement solutions to wicked problems. We close by discussing limitations of this work and future directions in studying collective environmental literacy.

Characterizing group and individual engagement in intergroup encounters between small groups of ring-tailed lemurs (Lemur catta) on St. Catherines Island, USA

Primate species exhibit considerable variation in behavior and outcomes during intergroup encounters (IGEs). Social group characteristics, like group size, and individual traits, such as sex, rank, and reproductive status, within those groups can influence both IGE engagement and outcomes. To better understand the impact of group heterogeneity on IGEs, we must examine individual strategies to elucidate individual costs and benefits of engaging in these interactions. Here, we present a descriptive study of the IGEs between two small social groups of ring-tailed lemurs (Lemur catta) on St. Catherines Island, GA, USA. We distinguish between dyadic and multiple-individual interactions between groups to compare collective and individual agonistic engagement. All encounters occurred when the East Road group (N = 7 individuals) traveled from the center of their home range to the boundary with Windmill group's (N = 5 individuals) home range, indicating that East Road might have been actively testing this boundary for access to food resources, sleeping trees, and mating opportunities. We also found notable individual variation in participation during IGEs. The daughters of the highest-ranking females were the most-engaged in dyadic intergroup and intragroup aggression, had high "win" rates during intergroup dyadic encounters, and engaged in intergroup multiple-individual interactions at high levels. These findings indicate that they might value their home range more as "potential alphas" compared to other group members. Dominant females were the most engaged in multiple-individual interactions, suggesting that they contribute heavily to collective action that might result in a gain or loss of access to resources. Finally, these two small groups might be equally matched despite the two-individual group size disparity due to individual free-riding strategies. Future research should focus on individual strategies during IGEs to characterize the complex decisions and trade-offs that influence participation.

Multi-level gains of fat activism and their impact on sustained activism for fat justice

Previous research has indicated that outcomes of collective action can occur at the individual, group, and societal levels. Taken together, we argue that multi-level outcomes can influence sustained involvement in social movements. We aimed to examine the multi-level outcomes of fat activism across two studies. In our first study, we conducted semi-structured interviews with fat activists (N = 20) to learn what they believe are the multi-level outcomes of fat activism. At the individual level, activists reported greater health, well-being, and self-esteem; at the group level, they reported a sense of community and increased clothing options; and at the societal level, they reported change in toxic cultures around dieting. By building on the findings of Study 1, Study 2 (N = 464) aimed to understand how fat individuals' past collective action participation may predict their future collective action participation through individual-, group-, and societal-level gains. Results indicate that greater collective action participation in the past predicts greater willingness to engage in collective action through the pathway of higher beliefs in individual and societal gains of fat activism, but not through group-level gains, even after we control for identification with fat and fat activist identities. We discuss these findings in relation to the importance of multi-level outcomes in collective action and sustained involvement in social movements.

Climate change and COVID-19: Interdisciplinary perspectives from two global crises

The repercussions of the COVID-19 pandemic and climate change - two major current global crises - are far-reaching, the parallels between the two are striking, and their influence on one another are significant. Based on the wealth of evidence that has emerged from the scientific literature during the first two years of the pandemic, this study argues that these two global crises require holistic multisectoral mitigation strategies. Despite being different in nature, neither crisis can be effectively mitigated without considering their interdependencies. Herein, significant interactions between these two crises are highlighted and discussed. Major implications related to the economy, energy, technology, environment, food systems and agriculture sector, health systems, policy, management, and communities are detailed via a review of existing joint literature. Based on these outcomes, practical recommendations for future research and management are provided. While the joint timing of these crises has created a global conundrum, the COVID-19 pandemic has demonstrated opportunities and lessons for devising sustainable recovery plans in relation to the climate crisis. The findings indicated that governments should work collaboratively to develop durable and adjustable strategies in line with long-term, global decarbonisation targets, promote renewable energy resources, integrate climate change into environmental policies, prioritise climate-smart agriculture and local food systems, and ensure public and ecosystem health. Further, differences in geographic distributions of climate change and COVID-19 related death cases revealed that these crises pose different threats to different parts of the world. These learnings provide insights to address the climate emergency - and potential future global problems with similar characteristics - if international countries act urgently and collectively.

What predicts climate change activism?: An examination of how depressive symptoms, climate change distress, and social norms are associated with climate change activism

BACKGROUND

The current and future harms caused by climate change are highly distressing. Different theoretical models suggest diverse impacts of distress on behavior. We examined how psychological distress, climate change distress, and social norms may foster or impede climate change activism.

METHODS

As part of an ongoing online longitudinal study in the US beginning in March 2020, respondents were assessed on their depressive symptoms (CES-D 10), climate change distress, climate change mitigation social norms, and six outcomes of the climate change activism behaviors of writing letters, e-mailing, or phoning government officials; voting for candidates who support measures to reduce climate change; signing petitions; volunteering with organizations; donating money to organizations; and attending protests.

RESULTS

Of the 775 respondents, 53% were female, 72% white, 12% Black, 7% Hispanic, and 6% Asian. Climate change social norms predicted all six climate change actions in the bivariate and multivariable cross-sectional logistic regression models. A similar finding was observed with the brief climate change distress scale (BCCDS), except it was not associated with volunteering in the multivariable model. Depressive symptoms were associated with greater odds of contacting government officials and signing petitions in the bivariate models but did not retain significance in the multivariable models. Longitudinal models indicated a weak association between depressive symptoms and climate change activism.

CONCLUSIONS

Climate change distress and social norms are positively associated with climate change activism. Although climate change distress may not usually impede climate change activism, organizations addressing climate change should consider providing social support to members and assisting those with high levels of psychological and climate change distress. Social norms around climate change activism should be fostered.

A collective call to strengthen monitoring and evaluation efforts to support healthy and sustainable food systems: 'The Accountability Pact'

There is widespread agreement among experts that a fundamental reorientation of global, regional, national and local food systems is needed to achieve the UN Sustainable Development Goals Agenda and address the linked challenges of undernutrition, obesity and climate change described as the Global Syndemic. Recognising the urgency of this imperative, a wide range of global stakeholders - governments, civil society, academia, agri-food industry, business leaders and donors - convened at the September 2021 UN Food Systems Summit to coordinate numerous statements, commitments and declarations for action to transform food systems. As the dust settles, how will they be pieced together, how will governments and food corporations be held to account and by whom? New data, analytical methods and global coalitions have created an opportunity and a need for those working in food systems monitoring to scale up and connect their efforts in order to inform and strengthen accountability actions for food systems. To this end, we present - and encourage stakeholders to join or support - an Accountability Pact to catalyse an evidence-informed transformation of current food systems to promote human and ecological health and wellbeing, social equity and economic prosperity.

Perspectives of peripartum people on opportunities for personal and collective action to reduce exposure to everyday chemicals: Focus groups to inform exposure report-back

Participants in biomonitoring studies who receive personal exposure reports seek information to reduce exposures. Many chemical exposures are driven by systems-level policies rather than individual actions; therefore, change requires engagement in collective action. Participants' perceptions of collective action and use of report-back to support engagement remain unclear. We conducted virtual focus groups during summer 2020 in a diverse group of peripartum people from cohorts in the Environmental influences on Child Health Outcomes (ECHO) Program (N = 18). We assessed baseline exposure and collective action experience, and report-back preferences. Participants were motivated to protect the health of their families and communities despite significant time and cognitive burdens. They requested time-conscious tactics and accessible information to enable action to reduce individual and collective exposures. Participant input informed the design of digital report-back in the cohorts. This study highlights opportunities to shift responsibility from individuals to policymakers to reduce chemical exposures at the systems level.

Using the Constitutionality Framework to Understand Alliances, Collective Action, and Divisions Between Indigenous and Peasant Communities in the Chaco Salteño

This article analyzes bottom-up institution-building processes in a region considered deforestation and environmental degradation hotspot. Utilizing the constitutionality approach developed by Haller, Acciaioli, and Rist (2016), we examine two recent cases of bottom-up institution-building in the department of Rivadavia, Chaco Salteño, Argentina. We highlight the similarities and differences between both constitutionality processes and identify various weaknesses in the two cases. We argue that constitutionality, understood as a process, has occurred to different (incomplete) degrees in each case. Finally, we show that external catalyzing agents play a decisive role in enabling or hampering the constitutionality process. Our study contributes to the literature on common-pool resource governance by highlighting how collective action can lead to participatory-development processes.

Prosociality predicts individual behavior and collective outcomes in the COVID-19 pandemic

The COVID-19 pandemic induces a social dilemma: engaging in preventive health behaviors is costly for individuals but generates benefits that also accrue to society at large. The extent to which individuals internalize the social impact of their actions may depend on their prosociality, i.e. the willingness to behave in a way that mostly benefits other people. We conduct a nationally representative online survey in Germany (n = 5843) to investigate the role of prosociality in reducing the spread of COVID-19 during the second coronavirus wave. At the individual level, higher prosociality is strongly positively related to compliance with public health behaviors such as mask wearing and social distancing. A one standard deviation (SD) increase in prosociality is associated with a 0.3 SD increase in compliance (p < 0.01). At the regional (NUTS-2) level, a one SD higher average prosociality is associated with an 11% lower weekly incidence rate (p < 0.01), and a 2%p lower weekly growth rate (p < 0.01) of COVID-19 cases, controlling for a host of demographic and socio-economic factors. This association is driven by higher compliance with public health behaviors in regions with higher prosociality. Our correlational results thus support the common notion that voluntary behavioral change plays a vital role in fighting the pandemic and, more generally, that social preferences may determine collective action outcomes of a society.

Perceived legitimacy of weight-based discrimination: Consequences for group identity, collective action, body satisfaction, and self-esteem

The present research applied the social identity approach to examine how the perceived legitimacy of weight-based discrimination among ingroup members influences their experience of their higher-weight identity and their well-being, and the conditions under which this occurs. Specifically, we investigated whether portraying weight-based discrimination as legitimate, as opposed to illegitimate, influenced higher-weight individuals' group identification, intentions to engage in collective action on behalf of their group, and their body satisfaction and self-esteem. The moderating role of group boundary permeability and the mediating role of group identification were also examined. North American adults with a self-reported BMI of or above 30 (N = 327) were randomly assigned to one of two experimental conditions: weight-based discrimination that was portrayed as legitimate or illegitimate by other ingroup members. Results revealed that portraying weight-based discrimination as being perceived as legitimate (versus illegitimate) among ingroup members significantly reduced group identification, but only among those who perceived their group's boundaries to be more permeable. For this particular group, reduced identification predicted, in turn, lower collective action intentions, body satisfaction, and self-esteem. This study highlights the damaging effect of legitimized discrimination for ingroup identification and the downstream consequences for collective action and well-being.

A theory of scaling for community-based fisheries management

Community-based approaches to fisheries management has emerged as a mainstream strategy to govern dispersed, diverse and dynamic small scale fisheries. However, amplifying local community led sustainability outcomes remains an enduring challenge. We seek to fill a theoretical gap in the conceptualization of 'scaling up community-based fisheries management'. We draw on literature of agriculture innovations to provide a framework that takes into account process-driven and structural change occurring across multiple levels of governance, as well as different phases of scaling. We hypothesize that successful scaling requires engagement with all aspects of a governing regime, coalescing a range of actors, and therefore, is an enterprise that is larger than its parts. To demonstrate where the framework offers value, we illustrate the development of community-based fisheries management in Vanuatu according to the framework's main scaling dimensions.

Socio-political efficacy explains increase in New Zealanders' pro-environmental attitudes due to COVID-19

The ongoing COVID-19 pandemic claimed millions of lives and caused unprecedented disruptions. Despite these negative impacts, there is optimism the pandemic may shift public opinion on other global crises by fostering a sense of collective efficacy. Using propensity score matching to compare New Zealanders assessed before (n =12,304) and after (n = 12,370) nationwide lockdowns in 2020, we tested a preregistered mediation model with COVID-19 lockdown experience predicting increases in pro-environmental attitudes via enhanced socio-political efficacy. As hypothesized, socio-political efficacy increased after the successful nationwide lockdowns. In turn, socio-political efficacy amplified respondents' pro-environmental attitudes including climate beliefs and concern, as well as support for a government subsidy for public transport and opposition to government spending on new motorways. The pandemic also enhanced respondents' satisfaction with the quality of the natural environment, which was unmediated by socio-political efficacy. The crisis might offer an opportunity to foster collective pro-environmental actions.

An integrative framework for transformative social change: a case in global wildlife trade

To achieve a sustainable future, it is imperative to transform human actions collectively and underlying social structures. Decades of research in social sciences have offered complementary insights into how such transformations might occur. However, these insights largely remain disjunct and of limited scope, such that strategies for solving global environmental challenges remain elusive. There is a need to integrate approaches focusing on individuals and social structures to understand how individual actions influence and are in turn influenced by social structures and norms. In this paper, we synthesize a range of insights across different schools of thought and integrate them in a novel framework for transformative social change. Our framework explains the relationships among individual behaviors, collective actions, and social structures and helps change agents guide societal transitions toward environmental sustainability. We apply this framework to the global wildlife trade-which presents several distinct challenges of human actions, especially amidst the Covid-19 pandemic-and identify pathways toward transformative change. One key distinction we make is between different individual actions that comprise the practice itself (e.g., buying wildlife products; private action) and those that push for a broader system change in practice (e.g., signaling (dis)approval for wildlife consumption; social-signaling action, and campaigning for policies that end unsustainable wildlife trade; system-changing action). In general, transformative change will require an integrative approach that includes both structural reforms and all three classes of individual action.

Development as Liberation

At a point in history where the worlds social and ecological boundaries are at a true testing point, this article presents some thoughts and questions around the tensions between reformist and revolutionary actions and ends in presenting dreaming as a tool towards emancipation. Through these thoughts, collective action is a central cog towards meaningful progress.

Social capital and the spread of covid-19: Insights from european countries

We investigate the effect of social capital on health outcomes during the Covid-19 pandemic in independent analyses for Austria, Germany, Great Britain, Italy, the Netherlands, Sweden and Switzerland. Exploiting detailed geographical variation within countries, we show that a one-standard-deviation increase in social capital leads to between 14% and 34% fewer Covid-19 cases per capita accumulated from mid-March until end of June 2020, as well as between 6% and 35% fewer excess deaths per capita. Our results highlight the positive health returns of strengthening social capital.

Editorial overview: Six messages of climate psychology

In response to the climate emergency, psychologists have produced a surge of theoretical and empirical work on climate change over the past fifteen years. For this editorial, we outline six messages of climate psychology that emerge from this growing corpus of work. Three messages focus on how to promote sustainable behavior change among individuals: 1) harness individual motivation, 2) nurture pro-climate norms, and 3) address individual resistance. The others focus on how to support collective efforts to resist an unsustainable status quo and work together for a more sustainable future: 4) recognize collective struggles, 5) elevate transformational narratives, and 6) pursue durable peace. These messages highlight the importance of personal experiences and intergroup dynamics for understanding and addressing the climate crisis.

Dietary behaviour as a form of collective action: A social identity model of vegan activism

Adopting plant-based, or vegan, diets can have a number of benefits, including mitigating climate change, promoting animal welfare, or improving public health. In the current research, we use social psychological theory to better understand what motivates vegans to engage in collective action on behalf of this social group - that is, what motivates individuals to promote, or encourage others to adopt, a vegan lifestyle. We develop and test a Social Identity Model of Vegan Activism, which highlights the roles of individuals' social identities, sense of efficacy, emotions and moral convictions in fostering collective action. In two pre-registered studies, the first with self-identified vegans from Australia and the UK (N = 351), and the second with self-identified vegans from the UK and the US (N = 340), we found that individuals more frequently engaged in vegan activism (i.e., actions to promote vegan lifestyles) when they had stronger moral convictions (i.e., deontological or consequentialist), greater collective efficacy (i.e., beliefs that vegans can make a positive difference), anger (i.e., when thinking about the reasons why they are vegan), and identification (both with vegans, and with animals). Deontological and consequentialist moral convictions had significant indirect effects on vegan activism via different mediators. We conclude by discussing the implications and importance of studying dietary behavior from a social identity perspective, including its ability to help explain how and why individuals become motivated to not only adopt a certain (e.g., vegan) lifestyle themselves, but to also 'act collectively' on behalf of that shared group membership (e.g., promote vegan-friendly behaviors). We also highlight some key insights for policy makers and campaigners aiming to promote plant-based diets.

A Systems View of Emotion in Socio-political Context

Most work to date in psychology and related sciences has examined simple, unidirectional causal processes of emotion affecting socio-political context or vice versa. In this classic, mechanistic view of science, each empirical observation stands on its own as a piece of some grander, not yet understandable, puzzle of nature. There have been repeated calls to eschew classic approaches in favor of systems meta-theory in psychology and related sciences. In this paper, we join these calls by arguing that systems meta-theory can better enable the study of emotions in socio-political contexts. We offer a brief primer on systems meta-theory, delineating three key beneficial features: multi-leveled, complex, and dynamic. Viewing emotion as a system of systems-within the person, their relationships (to others), and within the world (locally and globally)-enables fresh theory, method, and statistical analysis well suited to the study of emotion in a socio-political context.

Woodlot management and livelihoods in a tropical conservation landscape

In biodiversity hotspots, there is often tension between human needs and conservation, exacerbated when protected areas prevent access to natural resources. Forest-dependent people may compensate for exclusion by managing unprotected forests or cultivating planted woodlots. Outside Bwindi Impenetrable National Park in Uganda, household wood product needs are high and population growth puts pressure on the environment. We investigated the role of privately and collectively managed woodlots in provisioning wood products and supporting local livelihoods. We found that households relied heavily on woodlots for daily needs and as resources during time of need. We also found that locally relevant social institutions, called stretcher groups, played a role in the management of woodlots, providing shared community resources. Privately and collectively owned woodlots support local livelihoods and wood product needs in the region. Long-term management of forests in Uganda should consider the value of woodlots and the mechanisms required to support them.

Coastal Community Resilience and Power in the United States: A Comparative Analysis of Adaptability in North Carolina and Louisiana

Community adaptations to increase resilience and reduce vulnerability depend on adaptability, which is constituted by how power shapes collective mobilization of differential capacities across scales and levels of governance systems. A multidimensional power framework (MPF) to track the role of power in adaptability is presented and applied in a qualitative, comparative case study of two historical fishing communities in the United States. The MPF conceptualizes power as differential capacities at the individual and group levels, structural at the policy level, and systemic, reflective of generalized norms, strategies, and technologies of political economic imperatives. The first case, Two Rivers, North Carolina represents an example of collective action failure resulting in transformation to a new resilience regime consisting of fundamentally altered community functions, structures, and identity. The second case, Delcambre, Louisiana represents collective action success; community adaptations resulted in continuity in change for fisher livelihoods. Success here is defined as the ability to maintain a semblance of structure, function, or identity of the original resilience regime without connotations of positive or negative desirability. The cases were similar in demographics, vulnerabilities, and differential capacities. Key differences existed in systemic political economic imperatives, structural power at the policy level, and the ways closure, the ability to enforce a common sense of place within the communities reflected systemic power. The utility of the MPF is mapping vulnerabilities and differential capacities against broader structures and systemic processes to inform effective mobilization for improved socio-ecological resilience and sustainability.

Expressive suppression as an obstacle to social change: Linking system justification, emotion regulation, and collective action

Research on system justification theory suggests that justifying the societal status quo decreases negative emotions, leading to less collective action. In this investigation, we propose that the degree to which negative emotions mediate the link between system justification and collective action may depend upon whether individuals tend to suppress the expression of their negative emotions. We tested this hypothesis in the diverse socio-political contexts of Turkey, Israel, and the U.S. In one correlational study (Study 1) and three experimental studies (Studies 2-4), we observed that the link between system justification and willingness to participate in collective action through anger (Studies 1-2 and 4) and guilt (Study 3) was moderated by expressive suppression. We found that negative emotions mediated the association between system justification and collective action among those who suppress the expression of their emotions less frequently, but not those who use expressive suppression more frequently. These findings suggest that emotion regulation may undermine, rather than facilitate, efforts to engage in collective action even among people who are low in system justification.

Factors Influencing Family Forest Owners' Interest in Community-led Collective Invasive Plant Management

Effective invasive plant management requires collective action. However, little is known about what motivates individuals to work collectively. We conducted a mail survey of 2,600 randomly selected family forest owners in Indiana, USA to examine factors associated with community-led collective action. Specifically, we examined the role of perceived self-efficacy, perceived collective efficacy, concerns about invasive plants, and social norms associated with invasive plant management in shaping family forest owners' self-reported likelihood to work with their neighbors to remove invasive plants. We found that past experience talking to others or working with neighbors to remove invasive plants were important predictors of landowners' intention to work collectively, as were perceived self-efficacy in their own ability to manage invasive plants, perceived need for collective action, social norms, and concerns about invasive plants on neighboring or nearby properties. However, most socio-demographic characteristics (e.g., age, gender, education level, income) and land ownership characteristics (e.g., residence status, having a written forest management plan) were not statisically significant predictors of family forest owners' likelihood to work with their neighbors. Our findings suggest that building individual sense of competence, facilitating neighbor interactions, and strengthening shared concerns may facilitate community-led collective action to manage invasive plants.

Resistance as a form of resilience in sexual and gender minorities: Differential moderating roles of collective action on the discrimination-depression relationship among sexual minority men and women

BACKGROUND

As a fundamental means for transforming and advancing the conditions of lesbian, gay, bisexual, and transgender (LGBT) individuals, collective action has gained increasing attention in research, policy, and practice over the past decade. While collective action is influential in driving public awareness and policy changes, less is known about its psychological effects on individuals undertaking collective action.

METHODS

The present study developed a scale to measure collective action for LGBT rights and examined the underlying dimensions of collective action in a sample of 1050 LGBT individuals in Hong Kong. The moderating roles of collective action on the relationship between perceived discrimination and depressive symptoms were also examined.

RESULTS

The LGBT Collective Action Scale measured two dimensions of collective action, i.e., private and public collective action. Private collective action moderated the association between perceived discrimination and depressive symptoms among sexual minority men and women; however, the moderating effect of public collective action was only found in sexual minority women.

CONCLUSIONS

These differential moderating effects could be attributed to gender role socialization and gender-specific coping mechanisms in response to minority stress. Although public collective action is more powerful in triggering structural changes than private collective action, individuals in less democratic societies may not necessarily have access to public collective action due to the absence of opportunity structures. Private collective action, which is able to be initiated and undertaken individually, can be directed to transform heterosexist biases in interpersonal context. For LGBT individuals in less democratic societies, private collective action may be a more manageable way to maintain mental health in the face of stigmatization.

Collective climate action: When do people turn into collective environmental agents?

Effectively protecting the climate requires the action of groups. In the present review article, we aim to understand when individuals turn into collective climate actors. We first discuss pertinent models of group-based action and their relevance for explaining climate action. Then, we review recent research on how collective climate action is driven by ingroup identification, social norms, group-based emotions, and collective efficacy. Finally, we focus on when and why people feel a sense of collective agency aiming at inspiring a novel research agenda on collective climate action.

Estimating effects of cooperative membership on farmers' safe production behaviors: evidence from the rice sector in China

The current agricultural system in China highly depends on chemical fertilizers and pesticides. Consequently, agricultural production activities cause various environmental issues. Carrying out safe production provides vital support for sustainable development of agriculture, which may improve this situation. The past decades have witnessed the fast development of rural cooperatives organization in China. Given the fact that rural cooperative organization plays a crucial role in agricultural production, however, there is little empirical evidence on the relationship between cooperative membership and safe production of smallholders in China. This study aims to investigate whether the participation in farmer cooperatives contributes to safe production in agriculture in China. Using survey data covering 623 rice-producing farm households in Sichuan province in China, this study employs the endogenous switching regression model to examine the effects of the participation in farmer cooperatives on safe production in rice agriculture. The results show that cooperative membership has significantly positive effects on safe production in rice agriculture. In particular, the average treatment effects demonstrate that without the participation in cooperatives, the members' adoption of the green control techniques would reduce by 74.491%, the application of artificial weeding would reduce by 38.768%, and organic fertilizer input would reduce by 23.448%. Furthermore, the marginal treatment effect is employed to evaluate the heterogeneous effects of the participation in farmer cooperatives on safe production in rice agriculture. Heterogeneous effect analyses suggest that farmers who are more likely to participate in farmer cooperatives are easier to adopt green control technology, while farmers who are less likely to participate in farmer cooperatives are easier to adopt artificial weeding and increase organic fertilizer input. To improve safe production in rice agriculture, the Chinese government is expected to encourage rice farmers to participate in rural cooperative organizations, and to stimulate rice farmers to take collective action to address environment issues arising from agricultural production.

Collective action as a tool for agri-environmental policy implementation. The case of diffuse pollution control in European rural areas

In the European Union (EU) context, regulatory instruments and incentive schemes targeting individual farms remain the main policy instruments implemented to control diffuse pollution from agriculture. Yet, collective approaches to policy implementation have been recently developing. This article aims at assessing the potential for hybrid policy instruments relying on collective action among farmers to limit diffuse nitrate pollution from agriculture. Transaction cost economics are used to assess the potential advantages of collective action as a complement to regulatory and incentive policy tools. The conditions under which such hybrid forms of governance may be successful are identified using the Social-Ecological System (SES) framework. A review of empirical studies documenting cases of collective action for policy implementation in the EU context serves as a basis for the identification of the factors likely to affect the potential of collective approaches for water quality management in agriculture. The analysis relies more particularly on two cases: the Environmental Cooperatives in the Netherlands and the "Ferti-Mieux" operations in France. The results suggest that collective action is a relevant tool to consider for improving the effectiveness and cost-effectiveness of policies targeting diffuse pollution from agriculture. In particular, relying on farmers' cooperation for policy implementation may be associated with advantages in terms of transaction costs. However, such advantages will be effective under a number of conditions related to the characteristics of the water resource, the actors involved, the governance of cooperation and the broader economic and institutional contexts.

"I Feel Almost as Though I've Lived This Before": Insights from Sexual and Gender Minority Men on Coping with COVID-19

As communities struggle with how to cope with the health and social consequences of coronavirus disease 2019 (COVID-19), sexual and gender minority men living with or affected by the HIV/AIDS epidemic have important insights into how to cope with uncertainty, public health protocols, and grief. We recruited sexual and gender minority men using online networking apps from April 18-24, 2020 to enroll a longitudinal cohort. We analyzed baseline qualitative data from open-ended responses using content analysis to examine how the HIV/AIDS epidemic has helped sexual minority men with the current COVID-19 pandemic. Of the 437 participants who completed the survey, 155 (35%) indicated that HIV/AIDS had helped them cope with COVID-19. Free-response data from those 135 of those participants clustered around four themes: (1) experience having lived through a pandemic, (2) experience coping with stigma, (3) familiarity with public health protocols, and (4) belief in collective action. Based on the experiences of these men, public health approaches centered on resilience and collective action could be particularly helpful in responding and coping with COVID-19-especially if the pandemic persists over longer periods of time.

Culture, institutions and democratization

We construct a model of revolution and transition to democracy under individualistic and collectivist cultures. The main result is that, despite facing potentially more challenging collective action problems, countries with individualistic cultures are more likely to end up adopting democracy earlier than countries with collectivist cultures. Our empirical analysis suggests a strong and robust association between individualistic cultures and average polity scores and durations of democracy, even after controlling for other determinants of democracy emphasized in the literature. We provide evidence that countries with collectivist cultures also are more likely to experience autocratic breakdowns and transitions from autocracy to autocracy.

Social-psychological correlates of personal-sphere and diffusion behavior for wildscape gardening

Achieving conservation outcomes requires concerted engagement from many people across diverse societies. However, many conservation practitioners struggle to engage new audiences. Research suggests one effective strategy to reach nonengaged individuals is to encourage interested conservation actors to share information, provide resources and assistance, and organize local events to recruit others; we call these "diffusion behaviors." Previous studies suggest few conservation actors who engage in personal-sphere PEB also engage in diffusion PEB, potentially because these behaviors have unique barriers which have yet to be identified. We investigated if there are different psychosocial drivers of diffusion and personal-sphere PEB by surveying residents in Colorado, USA about their personal-sphere wildscape behaviors (e.g. planting native plants) and diffusion wildscape behaviors (e.g. helping a friend plant native plants). Including diffusion-specific psychosocial variables led to better predictions of both personal-sphere and diffusion PEB. Diffusion-specific self-efficacy, social and environmental response efficacy, and reputational concerns about perceived competence were significant predictors of diffusion behavior. Diffusion-specific environmental response efficacy and injunctive norms enforced through sanctioning significantly predicted personal-sphere behavior. Personal-sphere self-efficacy and dynamic norm beliefs predicted both behavior types. Our findings suggest that research should consider personal-sphere and diffusion PEB as distinct domains and should investigate the power of diffusion-specific perceptions. Conservation outreach programs seeking to encourage diffusion of PEB may benefit from designing programming to try to change these perceptions.

Integrating endemic medicinal plants into the global value chains: the ecological degradation challenges and opportunities

Though innovations for sustainable management of natural resources have emerged over time, the rising demand for nature based health solutions and integration of endemic flora into global value chains could have adverse impacts on ecosystems. The ecological risks in the exploitation of the wild endemic medicinal plant resources are exacerbated by a myriad of agrotechnological risks and challenges that highly constrain their domestication. Successful exploitation and commercialisation of medicinal plants thus require a clear understanding of their demand and production systems or value chain analysis. Accordingly there is need for innovative approaches towards their integration into global value chains. Since quality and safety, traceability, certification, as well as consumer tastes and preferences are critical drivers in purchasing decisions by global consumers, they are inadvertently exploited to weaken Indigenous knowledge (IK), undermine common property rights and entrench value chains that favour a few elite buyers. This tend to create pervasive incentives for overexploitation of medicinal plant resources and environmental degradation. Potential solution lies in the recognition of drivers of vulnerability to environmental degradation and the innovative use of policy bricolage, feedback loops and interactions between knowledge, power and agency on one hand, and collective action and property rights institutions on the other hand. We conceptualise a framework that can mediate a transformational agenda and enhance systematic understanding of sustainability lenses in endemic medicinal plant resources value chains. This could strengthen IK, enhance collective action and promote participation of local actors with positive impact on the utilisation and integration of endemic medicinal plant resources into global value chains.

Social capital and community disaster resilience: post-earthquake tourism recovery on Gili Trawangan, Indonesia

This study examines the hypothesis that social capital can be a foundation for community disaster resilience with an analysis of empirical findings from the August 2018 earthquake recovery on Gili Trawangan, Indonesia, a globally known coastal tourism destination. Positive links between community social capital and community disaster resilience are hypothesized, but the extent to which an iterative and interdependent relationship is co-shaping both is less understood. Social capital can enable collective action, providing self-organized social, psychological, financial and material resources following a disaster, that may otherwise need to be provided externally. In turn, disasters create collective action problems where collective response and recovery process are needed, creating an institutional space where the degree of usefulness, meaning and function of social capital can be shaped, recognized and drawn upon, often where external aid is insufficient. These relationships can be observed following disasters, because individuals and communities are often linked through emotive and meaningful sequences of common experiences, actions and activities. Findings descriptively detail Gili Trawangan's response and recovery process through the events and activities that occurred, and are then theoretically analyzed with a social capital framework including bonding (within group), bridging (between group) and linking (across power and institutional) ties. Three conclusions can be summarized. (1) Community social capital and disaster resilience are iteratively co-shaped through collective experiences, actions and activities. (2) Understanding context is critical for understanding if and to what degree this relationship exists. (3) The mechanism through which social capital enhances resilience is that it can enable collective action that can lead to the provision of needed aid and services.

What do people benefit from a citizen science programme? Evidence from a Rwandan citizen science programme on malaria control

Background

Malaria control remains a challenge globally and in malaria-endemic countries in particular. In Rwanda, a citizen science programme has been set up to improve malaria control. Citizens are involved in collecting mosquito species and reporting mosquito nuisance. This study assessed what people benefit from such a citizen science programme. The analysis was conducted on how the citizen science programme influenced perceptions and behaviour related to malaria control.

Methods

This study employed a mixed-methods approach using dissemination workshops, a survey, and village meetings as the main data collection methods. Dissemination workshops and village meetings involved 112 volunteers of the citizen science programme and were conducted to explore: (1) the benefits of being involved in the programme and (2) different ways used to share malaria-related information to non-volunteers. The survey involved 328 people (110 volunteers and 218 non-volunteers) and was used to compare differences in malaria-related perceptions and behaviour over time (between 2017 and 2019), as well as between volunteers and non-volunteers.

Results

Malaria-related perceptions and behaviour changed significantly over time (between 2017 and 2019) and became favourable to malaria control. When the findings were compared between volunteers and non-volunteers, for perceptions, only perceived self-efficacy showed a significant difference between these two groups. However, volunteers showed significantly more social interaction, participation in malaria-related activities at the community level, and indoor residual spraying (IRS) acceptance. In addition, both volunteers and non-volunteers reported to have gained knowledge and skills about the use of malaria control measures in general, and mosquito species in particular among volunteers.

Conclusion

The reported knowledge and skills gained among non-volunteers indicate a diffusion of the citizen science programme-related information in the community. Thus, the citizen science programme has the potential to provide individual and collective benefits to volunteers and society at large.

Addressing the triple burden of malnutrition in the time of COVID-19 and climate change in Small Island Developing States: what role for improved local food production?

The impacts of the COVID-19 pandemic on food and nutrition insecurity are likely to be significant for Small Island Developing States due to their high dependence on foreign tourism, reliance on imported foods and underdeveloped local food production systems. SIDS are already experiencing high rates of nutrition-related death and disability, including double and triple burdens of malnutrition due to unhealthy diets. We consider the potential role for improved local food production to offset the severity of food system shocks in SIDS and identify the need for localized approaches to embrace systems thinking in order to facilitate communication, coordination and build resilience.
