We present an evolutionary framework to help identify the dynamic factors that shape polycentric system variations and that drive particular trajectories of polycentric formation. Building on prior work, we argue that polycentric institutions for resource management emerge out of spatially delimited conflicts over resource use and the externalities that they entail. Our perspective points to the characteristics and conditions of the resource itself as a starting point that crescively shapes landscape-level patterns of resource use. We illustrate this process through a case study of the evolution of a polycentric system in California’s San Gabriel River Watershed. The study found a relationship between pronounced hydrologic linkages and stronger institutional linkages, suggesting that the physical characteristics of common-pool resources are one driver of subsequent institutional linkages. We also found that the impacts from resource use leads to both conflict and cooperation between basin users that shapes institutional formation and subsequent institutional interactions. This points to user impacts as a second important driver of polycentric formation over time. A better understanding of the evolutionary process of polycentric formation can illuminate opportunities to develop more cooperative relationships that support sustainable groundwater management.</p>\u0000<p>The post How did we get here?

The core collaborative community science framework differs from more typical frameworks for community science, which often frame projects as static and either scientist or community led; these framings can limit the potential for co-production and action-oriented models of science. Frameworks are lacking to help community science collaborators determine the contributions and leadership needed to initiate, sustain, and link together multiple projects that jointly support local learning and action, as well as contribute to broader scientific knowledge of complex social-ecological systems. The core collaborative community science framework offers three main innovations and contributions: (1) It invests in a core collaborative group structure, designed to increase community capacity and resilience through an expanded network of partners dedicated to the reduction of systematic inequities and injustices; (2) It seeds and supports multiple, diverse research projects implemented across complex social-ecological systems, focusing first on community-identified needs, and then on the questions community science can help answer; and (3) It facilitates dynamic shared responsibilities and leadership for partners from community, research, and government institutions, recognizing the need for shared contributions at all project phases. We offer examples from the Green Duwamish Learning Landscape in Washington, USA to show how project partners have coordinated their work focused on social, ecological, and human health and navigated challenges related to funding, staffing, and governance. We share insights on how to help integrate community science within the social fabric of communities, especially those faced with environmental health and justice challenges.</p>\u0000<p>The post Joining collective impact and community science: a framework for core collaborative community science first appeared on Ecology & Society.</p>","PeriodicalId":51028,"journal":{"name":"Ecology and Society","volume":"34 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140126207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Policy interventions by state and non-state organizations, such as regulations, economic incentives, and communication campaigns, can target fire use directly, or affect it indirectly, for example, by restricting land access. Yet evidence of such impacts has not been synthesized at the global scale. We analyzed 512 examples in 68 countries to describe the range of policy interventions by state and non-state organizations that target and/or affect fire use, categorizing interventions based on the broad actor types involved, their mode of operation (e.g., regulation) and their intentionality and/or possible effects vis-a-vis fire use. Of these interventions, 74% involved only state agencies in policy design and implementations, 4% involved only non-state organizations, and 18% involved collaboration between state and/or non-state organizations and/or communities. Three hundred and nine interventions directly targeted fire use, of which 87% aimed to eliminate or constrain fire use. Two hundred and three affected fire use indirectly, of which 88% led to reductions in or constraints upon fire use. Though there is some recognition in the 21st century of a need, in certain contexts, to support local fire use, for reasons related to environmental justice, ecology, wildfire risk and climate change, the literature we reviewed points to several challenges for contemporary efforts toward this end. These include contradictions between policy interventions, mistrust between actors following histories of fire suppression, greater fuel loads increasing the risk of burning where fire has been suppressed, and the need to consider the indirect effects of other types of policy, such as those related to land tenure.</p>\u0000<p>The post How policy interventions influence burning to meet cultural and small-scale livelihood objectives first appeared on Ecology & Society.</p>","PeriodicalId":51028,"journal":{"name":"Ecology and Society","volume":"40 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140322645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Art and creative practice are uniquely suited to help facilitate change in these deeper transformational leverage points. However, understandings of how creative practices contribute to sustainability transformations are lacking in practice and fragmented across theory and research. This lack of understanding shapes how creative practices are evaluated and therefore funded and supported, limiting their potential for transformative impact. This paper presents the 9 Dimensions tool, created to support reflective and evaluative dialogues about links between creative practice and sustainability transformations. It was developed in a transdisciplinary process between the potential users of this tool: researchers, creative practitioners, policy makers, and funders. It also brings disciplinary perspectives on societal change from evaluation theory, sociology, anthropology, psychology, and more in connection with each other and with sustainability transformations, opening new possibilities for research. The framework consists of three categories of change, and nine dimensions: changing meanings (embodying, learning, and imagining); changing connections (caring, organizing, and inspiring); and changing power (co-creating, empowering, and subverting). We describe how the 9 Dimensions tool was developed, and describe each dimension and the structure of the tool. We report on an application of the 9 Dimensions tool to 20 creative practice projects across the European project Creative Practices for Transformational Futures (CreaTures). We discuss user reflections on the potential and challenges of the tool, and discuss insights gained from the analysis of the 20 projects.

These community-based conservancies (CBCs) were designed to benefit CBC members through regular payments, potential for wages, improved security, etc. We used a coupled-systems simulation approach to quantify potential changes in livestock numbers and pastoral well-being associated with the presence of CBC core and buffer areas, and we did so under the current frequency of droughts and increased frequency associated with climate change. The interannual precipitation coefficient of variation (CV) for our focal CBCs in Samburu County was 22% (706 mm average precipitation). We altered precipitation variability to span from 10% to 60% CV while maintaining the average. Compared to a simulation with observed precipitation and all rangelands available, when herders did not use the CBC core areas and seasonally avoided buffer areas, there was an 11% decline in tropical livestock units supported. More predictable precipitation patterns supported more livestock and improved pastoral well-being. At CVs above 30%, dramatic declines in livestock populations were simulated. When drought was made moderately more frequent (i.e., CV from 22% to 27%) there was a 15% decline in the number of livestock. Members receive a variety of benefits as part of CBC communities, but payments are small for these CBCs, and most households do not receive payments. Our results suggest that, from an economic perspective alone, payments must be raised to make membership of residents in conservancies more tenable. Additional adaptive pathways and perhaps external supports will be needed in the future as the frequency of drought increases and livestock populations decrease.</p>\u0000<p>The post Drought frequency, conservancies, and pastoral household well-being first appeared on Ecology & Society.</p>","PeriodicalId":51028,"journal":{"name":"Ecology and Society","volume":"36 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140126298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Few studies, however, have investigated how these INGOs operate, what challenges they face, and what conditions support them to successfully promote the implementation of EbA. To address this knowledge gap, the literature on international boundary work and boundary organizations was first reviewed, deriving four categories of conditions for a successful promotion of EbA: knowledge, networks, resources, and context. Next, we applied this framework in a case study of the International Union for Conservation (IUCN) and the Foundation of Netherlands Volunteers (SNV) led EbA project on the restoration and sustainable use of mangroves in two provinces, Ca Mau and Ben Tre, which are located in the Vietnamese Mekong Delta. We interviewed 25 key informants representing INGOs, Vietnamese governmental agencies, farmers, scientists, and market parties. Our case study not only revealed how most literature-based success conditions were met but also found some additional conditions. We found that INGOs will have a greater chance of successfully promoting the implementation of the EbA in cases in which they can act as a knowledge broker, have a strong international network, can supply enough resources, and use context-specific strategies.

Practical approaches to identifying and monitoring social and cultural aspects of communities’ relationships with their environment could assist many agencies in understanding the impacts of their efforts to achieve conservation goals. The Hawaiʻi Department of Land and Natural Resources, Division of Aquatic Resources (DAR) launched the Holomua Marine Initiative to collaborate and engage with communities to strengthen co-management efforts, which included integrating socio-cultural aspects into the planning and assessment of marine management. Our team, which included resource managers, Western and indigenous scientists, community leaders, students, agency, and university staff engaged in collaborative management efforts in Hawaiʻi, developed an approach to monitor the social and cultural impacts of DAR’s management actions. Through online collaborative workshops with community members and non-profit leaders engaged in marine conservation in Hawaiʻi, we co-developed socio-cultural principles and indicators based on their reciprocal relationships with the nearshore environment. During the workshops, we used small group activities, snow cards, sorting, and categorization to generate nine fundamental principles, with associated indicators, to guide marine management in Hawaiʻi. Many of the principles and indicators are comparable to those developed in other parts of the Pacific, revolving around themes including the perpetuation of local and indigenous knowledge across generations, and access to land and natural resources. Participants also suggested themes less prevalent in other research, such as the need to evaluate impacts of tourism on community relationships with coastal areas. We offer recommendations for the development of socio-cultural principles and indicators in other place-based contexts, and emphasize the importance of on-going community collaboration. Developing a socio-cultural monitoring framework with community members impacted by marine management decisions could enable others engaged in collaborative efforts, including government agencies, to holistically understand and address impacts of their policies and actions. Monitoring layered socio-cultural impacts of marine management on local and indigenous communities has the potential to shift management goals, and enhance long-term effectiveness and support for initiatives to protect coastal resources worldwide.</p>\u0000<p>The post Holomua Marine Initiative: community-generated socio-cultural principles and indicators for marine conservation and management in Hawaiʻi first appeared on Ecology & Society.</p>","PeriodicalId":51028,"journal":{"name":"Ecology and Society","volume":"94 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139409685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meeting this complex challenge without unwarranted environmental degradation or loss of livelihoods requires understanding and managing the resilience of properties that produce natural resources. However, insufficient attention has been paid in research and natural resource governance to the capacity of natural resource producers to adapt and achieve sustainable outcomes at the property-level, potentially leading to unintended environmental and social outcomes. We used a large and detailed survey data of farmers, foresters, and growers in New Zealand to identify factors that correlate with property-level outcomes that are desirable from the perspective of sustainable natural resource production: strong environmental performance, good financial situation, and high well-being. The results detail how these outcomes correlate with diverse individual traits and outlooks, property-level agroecosystem characteristics, economic resources, and social interactions. However, different factors drive individual outcomes, and a factor that is positively correlated with one desirable outcome may negatively correlate with another. The only factor that positively correlated with all three outcomes was the goal to have strong environmental performance in future, which may reflect optimism as a resilience determinant. Thus, the difficulty of achieving good outcomes across all three dimensions may arise from conflicting effects of different factors on property-level environmental, economic, and well-being outcomes. In conclusion, our results indicate that natural resource governance must more carefully consider interdependencies between environmental, financial, and well-being outcomes at the property-level to support the ability of natural resource producers to meet society’s demands.</p>\u0000<p>The post Resilient and sustainable natural resource production: how are farmers and foresters coping? first appeared on Ecology & Society.</p>","PeriodicalId":51028,"journal":{"name":"Ecology and Society","volume":"270 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139459863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An interdisciplinary science team worked with resource managers and stakeholders to assess future forest ecosystem dynamics, given potential climatic changes and management strategies, across a 23,000-ha landscape in the Lake Tahoe basin of California and Nevada in support of the Lake Tahoe West Restoration Partnership. We projected forest growth and fire dynamics using a landscape change model, upon which the science team layered additional modeling to evaluate changes in wildlife habitat, water, and economics. Managers and stakeholders used the findings of this integrated modeling effort to inform the design of a landscape restoration strategy that balanced risks and benefits based on a robust scientific foundation. The results, published in this Special Feature, suggest that a continuation of status quo management would be less effective at protecting and improving desired outcomes than more active and extensive management approaches. In addition, the types of management activity also affected ecosystem outcomes. Results from across the studies in this special feature suggest that thinning and prescribed fire were complementary, although they resulted in somewhat different effects, and that low-severity use of fire had the greatest array and magnitude of ecosystem benefits. A notable exception was carbon storage, which declined with more active management and prescribed fire in particular. We highlight key findings from this Special Feature and summarize key challenges and some lessons learned in our experience of co-producing science. In short, science-management partnerships require cooperation, patience, and skill, but they are effective in increasing the capacity of land managers to navigate in an environment of rapid change and increasing uncertainty.</p>\u0000<p>The post Keeping up with the landscapes: promoting resilience in dynamic social-ecological systems first appeared on Ecology & Society.</p>","PeriodicalId":51028,"journal":{"name":"Ecology and Society","volume":"22 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139104428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intercropping has been promoted across Africa as a Striga control practice (SCP) and food security measure. Despite past efforts, millions of smallholder farmers (cultivating < 2 ha of maize) still struggle to implement SCPs. Social and ecological factors that prevent SCP implementation are well documented in the literature, but their underlying interactions have remained elusive. System dynamics modeling can uncover these interactions and assess their effect on intercropping rates as well as Striga emergence. This study presents a participatory mixed methods approach to build a system dynamics model based on two theories: diffusion of innovations and resource pool dynamics. The model estimates the population of fields where Striga emerged in response to intercropped fields when various interventions were implemented. According to model simulations, if new policies are not enacted to support intercropping, Striga is likely to spread to 2,625,000 maize fields, parasitizing almost 75% of smallholder farms across Central Malawi by 2036. The participatory approach allowed us to evaluate several policies, one of which sustained enough adopters to limit Striga emergence to < 500,000 fields, reducing the weed’s threat to food security. This policy considers how input costs and erratic rainfall can lead to disadoption, therefore, supporting the implementation of five to six consecutive years of intercropping by providing both fertilizer subsidies and demonstration plots. In this study, our participatory approach has shown to develop a model that can highlight interactions in social ecological systems, their leverage points, and how they can be exploited to develop effective food security policies.\u0000</p>\u0000<p>The post Technology adoption and weed emergence dynamics: social ecological modeling for maize-legume systems across Africa first appeared on Ecology & Society.</p>","PeriodicalId":51028,"journal":{"name":"Ecology and Society","volume":"46 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139104432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
