Few policies are more important to Indigenous Peoples living along the coast of so-called British Columbia than those that govern how and when fishing occurs, and by whom. The Doctrine of Priority underlies these policies, defining the ordered priority for fisheries management as: 1. conservation, 2. the constitutional right to fish held by Indigenous Peoples, and 3. commercial and sport fishing. Indigenous Peoples have, however, expressed frustration with fisheries management decisions that contradict the spirit of the Doctrine by jeopardizing the availability of sufficient fish to support the actualisation of their rights. Through a document analysis of 271 reasons for judgements from 196 legal cases, we trace how the Canadian courts have characterized the rights of Indigenous Peoples recognized and affirmed by Section 35 of the Constitution, including the right to fish. Informed by principles of social justice and Indigenous laws, we analyse five potential characterizations of the right to fish: activity, abundance, allocation, amount, and authority. Based on the reviewed case law, we find that the applicability of the Doctrine of Priority in contexts of uncertain resource abundance and ongoing reconciliation is far from a settled matter and one that is likely to remain unresolved if guidance is only sought from the Canadian courts. Instead, Indigenous Peoples working to ensure access to fish to support their communities are enacting their right to fish in meaningful and diverse ways –innovations key to understandings of the Doctrine of Priority and the pursuit of just fisheries.

对于居住在所谓的不列颠哥伦比亚省沿岸的土著居民来说，没有什么政策比这些政策更重要了，这些政策规定了捕鱼的方式、时间和对象。优先原则是这些政策的基础，它将渔业管理的先后优先次序定义为：保护,2。2 .土著人民的宪法捕鱼权；商业和运动钓鱼。然而，土著人民对渔业管理的决定表示失望，因为这些决定违背了《原则》的精神，损害了获得足够的鱼类来支持实现其权利。通过对196个法律案件的271个判决理由的文件分析，我们追溯了加拿大法院如何描述《宪法》第35条承认和肯定的土著人民的权利，包括捕鱼权。根据社会正义原则和土著法律，我们分析了捕鱼权的五个潜在特征：活动、丰度、分配、数量和权威。根据所审查的判例法，我们发现优先权原则在资源不确定丰富度和正在进行的和解背景下的适用性远远不是一个解决的问题，如果只从加拿大法院寻求指导，这个问题可能仍未解决。相反，土著人民正在努力确保获得鱼类资源以支持他们的社区，他们正在以有意义和多样化的方式颁布他们的捕鱼权利——这是理解优先原则和追求公正渔业的关键创新。

Landfill leachate (LL) is a dark effluent generated from the decomposition of municipal solid waste. Its composition is highly diverse and heterogeneous and is usually strongly influenced by the age and stage of operation of the LL. Globally, the annual generation of municipal solid waste exceeds 2 billion tons, and in 2020, the global direct cost of waste management was estimated at US$252 billion. Although several reviews on the subject exist, few address the relationship between LL’s physicochemical characteristics, its toxicity and a critical comparison of emerging treatment technologies. From 2019–2024, research on LL experienced a notable 31.4 % increase in scientific publications, reflecting the growing global attention to this environmental challenge. This study fills this gap by compiling and critically analyzing recent data, offering a consolidated and updated overview that supports the development of more effective solutions. A crucial finding is that due to the significant variability in LL composition, no single treatment method is sufficiently efficient to ensure the final quality and safety of the treated effluent. The author’s thorough assessment is presented at the end of each section, providing practical and scientific insights for researchers and environmental managers. The uniqueness of this review lies in the critical integration of data on LL characteristics, toxicity, and various treatment methods, inspiring the development of innovative and sustainable technologies, while also establishing connections between the findings and public policy frameworks. Furthermore, the relevance of this review is reinforced by its direct connection to the 2030 Agenda for Sustainable Development Goals (SDGs) and the main future challenges are discussed.

垃圾填埋场渗滤液（LL）是一种由城市固体废物分解产生的深色污水。它的组成是高度多样化和异质性的，通常受到LL的年龄和操作阶段的强烈影响。全球每年产生的城市固体废物超过20亿吨，到2020年，全球废物管理的直接成本估计为2520亿美元。虽然有一些关于该主题的评论，但很少涉及LL的物理化学特性，其毒性和新兴处理技术的关键比较之间的关系。从2019年到2024年，对LL的研究在科学出版物中显著增加了31.4% %，反映了全球对这一环境挑战的日益关注。本研究通过汇编和批判性地分析最近的数据来填补这一空白，提供了一个整合和更新的概述，支持开发更有效的解决方案。一个重要的发现是，由于LL组成的显著变化，没有一种处理方法足够有效，以确保处理后的流出物的最终质量和安全。作者的全面评估是在每个部分的末尾提出的，为研究人员和环境管理者提供实用和科学的见解。本综述的独特之处在于对LL特征、毒性和各种治疗方法的数据进行了关键的整合，激发了创新和可持续技术的发展，同时也在研究结果与公共政策框架之间建立了联系。此外，本次审查与2030年可持续发展目标议程（sdg）的直接联系加强了其相关性，并讨论了未来的主要挑战。

The genealogy of mining sustainability 采矿可持续性的谱系

Mining sustainability, a concept that emerged in the late 1990s, represents a radical break from traditional mining practices. Paradoxically, it also brought with it the recovery of the mining legacy debate. Driven by a serious economic crisis, and burdened by a tarnished reputation as a “dirty business”, large mining companies sought a dramatic change in image and discourse. At the same time, over the past two decades, industries and governments have aligned with themselves with sustainability initiatives and extensively examined mining legacies, particularly with regard to environmental liabilities. This article contributes to this debate from an emerging field, the exploration of historical mining pollution conflicts through the lens of political ecology and environmental justice. Recent research has shown a proliferation of such conflicts in the main mining basins. Dialectical struggles among the concerned social agents have offered valuable insights into the narratives adopted by mining companies. European, American and Canadian cases have revealed that mining companies responded to pollution challenges with a language of lasting influence that combined economic-political and technological-scientific arguments. Two phases of this process can be identified. A critical juncture emerged in the late nineteenth century, with globalization and the rise of large corporations prompting the construction of a coherent narrative based on past experience. This environmental memory resurfaced in the 1960s-1970s, significantly influencing the mining sustainability concept and practices. Initially, science and policy held a secondary position. However, they would later achieve a new status from the late nineteenth century onwards, making a fundamental contribution to the consolidation of this discourse. From an environmental justice perspective, this article concludes with a reflection on the role of policy and science in this corporate discourse.

矿业可持续性这个概念出现于上世纪90年代末，代表着对传统采矿实践的彻底突破。矛盾的是，它还带来了矿业遗产辩论的复苏。在严重的经济危机的推动下，再加上背负着“肮脏生意”的污名，大型矿业公司寻求在形象和话语上发生戏剧性的变化。与此同时，在过去二十年中，行业和政府与可持续发展倡议保持一致，并广泛审查了采矿遗产，特别是在环境责任方面。本文从一个新兴的领域，即通过政治生态学和环境正义的视角来探讨历史上的采矿污染冲突，为这场辩论做出贡献。最近的研究表明，这类冲突在主要的采矿盆地激增。有关社会行动者之间的辩证斗争为了解矿业公司采用的叙述提供了宝贵的见解。欧洲、美国和加拿大的案例表明，矿业公司用一种结合了经济-政治和技术-科学论证的具有持久影响力的语言来应对污染挑战。这个过程可以分为两个阶段。19世纪后期出现了一个关键时刻，全球化和大公司的崛起促使人们在过去经验的基础上构建连贯的叙事。这种环境记忆在20世纪60年代至70年代重新出现，极大地影响了采矿可持续性的概念和实践。最初，科学和政策处于次要地位。然而，他们后来从19世纪后期开始获得了新的地位，为巩固这一话语做出了根本性的贡献。从环境正义的角度出发，本文最后反思了政策和科学在这种企业话语中的作用。

Three forms of trust are contrasted: personal level trust (PLT), aggregated personal trust (APLT) and system-level trust (SLT). PLT and APLT are generally developed through face-to-face and other forms of direct relationships among participants in environmental governance. PLT and APLT, while unquestionably helpful and important in addressing environmental issues and policies, have proved insufficient to generate agreement and action in the face of today’s complex multi-scaled problems. These problems often affect larger populations, many numbers of which have no direct relationships with other stakeholders. Consequently, efforts at environmental governance in these cases often lack the support of appropriate levels of trust. It is shown that SLT cannot be built from either PLT or APLT; it requires delving into characteristics of the negotiating groups, themselves. Such groups are likely to find some success if: (1) they share a sense of place; (2) they acknowledge the importance of complexity in their work, and (3) they are focused on a shared problem or nest of problems. The concept of system-level trust is tested by application to collective actions in protecting common pool resources within multi-scaled systems incorporating polycentric governance.

本文对比了三种形式的信任：个人层面信任（PLT）、聚合个人信任（APLT）和系统层面信任（SLT）。PLT和applt一般是通过环境治理参与者之间面对面或其他形式的直接关系发展起来的。PLT和applt虽然在解决环境问题和政策方面毫无疑问是有帮助和重要的，但面对当今复杂的多尺度问题，它们已被证明不足以产生协议和行动。这些问题往往影响更大的人群，其中许多人与其他利益相关者没有直接关系。因此，在这些情况下，环境治理的努力往往缺乏适当程度的信任的支持。结果表明，SLT不能由PLT或APLT构建；这需要深入研究谈判小组本身的特点。如果：(1)他们有共同的地方感；(2)他们认识到复杂性在工作中的重要性，(3)他们专注于一个共同的问题或一系列问题。通过将系统级信任的概念应用于包含多中心治理的多尺度系统中保护公共池资源的集体行动，对系统级信任的概念进行了测试。

Amid escalating urban flood risks driven by climate change and poorly managed urban growth, there is growing recognition of the need to strengthen and integrate flood risk governance systems. However, existing governance arrangements in many cities remain fragmented, siloed, and inadequately inclusive. This paper addresses a critical gap in the literature by proposing and applying an Integrated Flood Risk Governance framework that systematically assesses governance integration through three interrelated dimensions: institutional interaction, actor relationships, and policy mixes. Drawing on policy document analysis and in-depth interviews, the study explores the applicability of the Integrated Flood Risk Governance framework in two high-risk urban settings: Lagos, Nigeria, and Accra, Ghana. The findings reveal that although integration is emphasized in formal policies, practical implementation is hampered by highly centralized governance structures, limited stakeholder participation, and weak coordination mechanisms. In both cities, the private sector remains marginally involved, and policy coherence is often undermined by poor enforcement and funding constraints. This study demonstrates the utility of the Integrated Flood Risk Governance framework in diagnosing governance fragmentation and highlights the need for more inclusive, adaptive, and participatory approaches to flood risk governance.

由于气候变化和管理不善的城市增长导致城市洪水风险不断升级，人们越来越认识到加强和整合洪水风险治理系统的必要性。然而，许多城市现有的治理安排仍然是分散的、孤立的、包容性不足的。本文提出并应用了一个综合洪水风险治理框架，该框架通过三个相互关联的维度系统地评估治理整合：制度互动、行动者关系和政策组合，从而弥补了文献中的一个关键空白。通过政策文件分析和深度访谈，本研究探讨了综合洪水风险治理框架在两个高风险城市环境中的适用性：尼日利亚拉各斯和加纳阿克拉。研究结果表明，尽管正式政策强调整合，但实际实施受到高度集中的治理结构、有限的利益相关者参与和薄弱的协调机制的阻碍。在这两个城市，私营部门仍然很少参与，政策一致性往往受到执法不力和资金限制的影响。本研究展示了综合洪水风险治理框架在诊断治理碎片化方面的效用，并强调需要采取更具包容性、适应性和参与性的洪水风险治理方法。

The dynamic nature of policy processes creates urgent knowledge needs that may not align with typical timelines of scientific research and knowledge synthesis. Faced with these time constraints, policy-makers resort to ad-hoc strategies to make decisions or resolve disputes, compromising the quality of evidence-based policy. As part of a project, we addressed this challenge by developing and testing a structured process for responding to urgent knowledge needs while maintaining scientific rigor. This process was tested in April 2023 through a knowledge-synthesis on the relationship between deadwood and fire risk in European forests, delivering evidence for ongoing EU Nature Restoration Law policy discussions. A targeted group of experts delivered a report within six weeks of initial request, following a scoping and engagement process. In this paper, we evaluate the context and outcomes of this rapid response process, prompting reflection on conditions necessary to respond in a timely manner. Our analysis reveals key challenges: knowledge production constraints, barriers to diverse expertise mobilization, limited transformative potential, science-policy interface tensions, specific ethical risks. To address these challenges, we identify four key requirements for rapid response processes: (1) sustained science-policy dialogue to clarify urgent needs and their context, (2) structured systems for accessing existing research, (3) incentivized expert engagement with clear participation pathways, (4) robust ethical oversight that maintains scientific integrity while acknowledging limitations. These requirements provide a foundation for developing ethically grounded, sustainable science-policy interactions that balance rigor with responsiveness, incorporate diverse knowledge systems, and enhance transformative potential across different contexts and scales.

政策过程的动态性造成了迫切的知识需求，这可能与科学研究和知识综合的典型时间表不一致。面对这些时间限制，政策制定者采取临时策略来做出决策或解决争端，从而损害了循证政策的质量。作为项目的一部分，我们通过开发和测试一个结构化的过程来应对这一挑战，该过程用于在保持科学严谨性的同时响应紧急知识需求。该过程于2023年4月通过对欧洲森林枯木与火灾风险之间关系的知识综合进行了测试，为正在进行的欧盟自然恢复法政策讨论提供了证据。经过范围界定和参与程序后，目标专家组在收到初步请求后六周内提交了一份报告。在本文中，我们评估了这一快速反应过程的背景和结果，促使人们反思及时反应所需的条件。我们的分析揭示了主要的挑战：知识生产限制、多样化专业知识动员的障碍、有限的变革潜力、科学-政策界面紧张、特定的伦理风险。为了应对这些挑战，我们确定了快速响应过程的四个关键要求：(1)持续的科学政策对话，以澄清迫切需求及其背景；(2)结构化的系统，以获取现有研究；(3)激励专家参与，明确参与途径；(4)强有力的伦理监督，在承认局限性的同时保持科学诚信。这些要求为发展以伦理为基础的、可持续的科学政策互动提供了基础，这些互动可以平衡严谨性与响应性，纳入多样化的知识系统，并增强不同背景和规模的变革潜力。

These requirements provide a foundation for developing ethically grounded, sustainable science-policy interactions that balance rigor with responsiveness, incorporate diverse knowledge systems, and enhance transformative potential across different contexts and scales.</div></div>","PeriodicalId":313,"journal":{"name":"Environmental Science & Policy","volume":"175 ","pages":"Article 104303"},"PeriodicalIF":5.2,"publicationDate":"2025-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145837411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study sought to identify the level and interaction of vulnerabilities to water, energy, and food (WEF) misgovernance, social injustice and insecurity, conceptualized through exposure, sensitivity and adaptative capacity. The study was carried out in Matatiele, Magareng and Greater Taung Local Municipalities, South Africa. Multi-stage purposive sampling was used to get a sample of 1184 households through semi-structured questionnaires in a cross-sectional survey. A vulnerability index, Monte Carlo Simulations and Structural Equation Modelling were used to analyse the data. The results showed high exposure to WEF misgovernance and high sensitivity to WEF social injustice, which resulted in high and low vulnerability to WEF misgovernance and social injustice, respectively. In addition, various levels of vulnerability to WEF social injustice had interaction with vulnerability to misgovernance and insecurities, respectively. Furthermore, there was a higher probability of experiencing vulnerability to WEF misgovernance than social injustice. However, there was a reinforcing positive association between vulnerabilities to WEF misgovernance and social injustice. In conclusion, there is a reinforcing association between experiencing vulnerability to WEF misgovernance and social injustice, which is also associated with vulnerability to water insecurity. However, vulnerabilities to social injustice counteract vulnerabilities to energy and food insecurity. The study recommends improving awareness on issues of misgovernance and social injustice at the household and community level. There is a need to incentivize participation in community forums and expand their composition to accommodate various social groups and classes. Policymakers also need to provide spatial and temporal-based indigent support to alleviate WEF insecurities.

该研究试图确定水、能源和食物（WEF）管理不善、社会不公正和不安全的脆弱性水平和相互作用，通过暴露、敏感性和适应能力进行概念化。这项研究是在南非的Matatiele、Magareng和Greater Taung地方市政当局进行的。采用横断面调查的半结构化问卷法，采用多阶段目的抽样法，抽取1184户家庭样本。利用脆弱性指数、蒙特卡罗模拟和结构方程模型对数据进行分析。结果表明：经济论坛治理不善的高暴露性和经济论坛社会不公的高敏感性，分别导致经济论坛治理不善和社会不公的高脆弱性和低脆弱性。此外，不同程度的WEF社会不公正脆弱性分别与治理不善脆弱性和不安全感脆弱性相互作用。此外，与社会不公正相比，遭受世界经济论坛治理不当影响的可能性更高。然而，对世界经济论坛管理不善的脆弱性与社会不公正之间存在着一种不断强化的正相关关系。总之，易受世界经济论坛管理不善影响与社会不公正之间的联系越来越强，而社会不公正也与易受水不安全影响有关。然而，社会不公正的脆弱性抵消了能源和粮食不安全的脆弱性。该研究建议在家庭和社区一级提高对管理不善和社会不公正问题的认识。有必要鼓励参与社区论坛，并扩大其组成，以容纳不同的社会群体和阶级。政策制定者还需要提供基于空间和时间的贫困支持，以减轻世界经济论坛的不安全感。

Regulatory decision-making for novel entities such as trifluoroacetic acid, respectively trifluoroacetate (TFA), involves multiple forms of uncertainty. This paper applies a typology that structures uncertainty along two dimensions: types of uncertainty (epistemological, ontological, and ambiguity) and objects of uncertainty (substantive, strategic, and institutional). We argue that three key substantive features of TFA, its large number of precursors, its extreme environmental persistence, and its global mobility, do not only shape substantive uncertainties about its properties, effects, and mitigation, but also amplify strategic and institutional uncertainties. Specifically, the wide and fragmented network of actors involved in TFA’s regulation across sectors (e.g., water, pesticides) creates diffuse responsibilities and complicates coordination. TFA’s persistence intensifies ontological uncertainties, as continuous and potentially irreversible exposure renders some long-term impacts effectively unknowable within relevant policy timeframes. Its mobility challenges regulatory systems that are spatially and institutionally bound. Importantly, we show how regulatory outcomes are shaped not only by substantive or institutional challenges but also by competing actor framings and power asymmetries, as actors strategically influence how regulatory uncertainties are defined and addressed. These findings are not just relevant for TFA regulation, but also for the broader group of novel entities where regulatory decision-making depends on measures such as emission reduction, improved input control, increased regulatory transparency, and sensitivity to power asymmetries. We propose that the applied typology can serve as a boundary object to foster interdisciplinary dialogue in environmental governance, bridging distinct philosophical and disciplinary perspectives while remaining sufficiently open to accommodate different conceptual and disciplinary framings of uncertainty. The applied typology shows how different types and objects of uncertainty interact in decision-making around novel entities.

对新实体（如三氟乙酸，即三氟乙酸酯）的监管决策涉及多种形式的不确定性。本文采用一种类型学，沿着两个维度构建不确定性：不确定性类型（认识论、本体论和模糊性）和不确定性对象（实质性、战略性和制度性）。我们认为，TFA的三个关键实质特征，即大量的前体、极端的环境持久性和全球流动性，不仅形成了其性质、影响和缓解方面的实质性不确定性，而且还放大了战略和制度的不确定性。具体而言，TFA跨部门（如水、农药）监管中涉及的行为者网络广泛而分散，造成责任分散，使协调复杂化。TFA的持续存在加剧了本体论的不确定性，因为持续的和潜在的不可逆转的暴露使得一些长期影响在相关的政策时间框架内实际上是不可知的。它的流动性挑战了受空间和制度约束的监管体系。重要的是，我们展示了监管结果如何不仅受到实质性或制度性挑战的影响，还受到竞争行为体框架和权力不对称的影响，因为行为体在战略上影响着监管不确定性的定义和解决方式。这些发现不仅适用于TFA监管，也适用于监管决策取决于减排、改进投入控制、提高监管透明度和对权力不对称敏感性等措施的更广泛的新型实体。我们建议，应用类型学可以作为一个边界对象，促进环境治理中的跨学科对话，弥合不同的哲学和学科观点，同时保持足够的开放性，以适应不确定性的不同概念和学科框架。应用类型学显示了不确定性的不同类型和对象如何在围绕新实体的决策中相互作用。

Green hydrogen (GH₂) is increasingly positioned as a cornerstone of the global energy transition, offering a pathway to reduce greenhouse gas emissions. However, its production entails socio-environmental risks such as biodiversity loss, land-use change, and intensive water consumption that are often underrepresented in public discourse. This study hypothesizes that, although GH₂ has gained global relevance, digital news media in strategic countries tend to underreport its socio-environmental challenges, influenced by local socioeconomic and informational contexts. The objective was to analyze how socio-environmental impacts of GH₂ are represented in freely accessible digital news media from 12 countries with diverse geographic, economic, and energy profiles. Using Google Advanced Search, the 100 most relevant articles per country (2012–2023) were collected, excluding blogs and opinion pieces. Articles were categorized by approach, scope, funding, energy source, impacts, and challenges. Data were compiled into a presence/absence matrix and analyzed with Principal Component Analysis (PCA), incorporating socioeconomic indicators such as GDP, Gini index, protected area coverage and WPFI. Results showed a predominance of economic and technological narratives, while socio-environmental risks appeared in less than 25 % of articles. Coverage varied among countries: Morocco and Chile highlighted water scarcity, whereas Brazil downplayed land-use pressures. PCA distinguished clusters, with emerging economies stressing exports and financing, while countries with higher biodiversity protection emphasized ecological risks. Overall, media discourse tended to “economize” GH₂, marginalizing environmental concerns and limiting critical debate. These patterns reinforce information asymmetries and highlight the need for more balanced communication to align GH₂ development with sustainability goals.

绿色氢（GH 2）日益被定位为全球能源转型的基石，为减少温室气体排放提供了一条途径。然而，它的生产带来了社会环境风险，如生物多样性丧失、土地利用变化和密集的水资源消耗，这些风险在公共话语中往往没有得到充分体现。本研究假设，尽管gh2已获得全球相关性，但受当地社会经济和信息背景的影响，战略国家的数字新闻媒体倾向于低估其社会环境挑战。目的是分析来自12个不同地理、经济和能源概况的国家的免费数字新闻媒体如何反映温室气体的社会环境影响。使用谷歌高级搜索，收集了每个国家（2012-2023）最相关的100篇文章，不包括博客和评论文章。文章按方法、范围、资金、能源来源、影响和挑战进行分类。将数据编制成存在/缺失矩阵，并结合GDP、基尼指数、保护区覆盖率和WPFI等社会经济指标，采用主成分分析（PCA）进行分析。结果显示，经济和技术叙事占主导地位，而社会环境风险出现在不到25% %的文章中。覆盖范围因国家而异：摩洛哥和智利强调了水资源短缺，而巴西则淡化了土地使用压力。PCA区分了集群，新兴经济体强调出口和融资，而生物多样性保护程度较高的国家强调生态风险。总体而言，媒体话语倾向于“节约”二氧化碳，将环境问题边缘化，并限制批判性辩论。这些模式加剧了信息不对称，并强调需要更平衡的沟通，以使温室气体的发展与可持续发展目标保持一致。

Sustainability science looks at who and what can continue to exist into the future. To do so, it must also grapple with ontological questions about what and who currently exists. Whereas people’s worlds are inhabited by vastly different entities and relationships, it is often only the entities that exist in dominant, science-based realities that are discussed in environmental research and policy. In such cases, a separation between objectivity and subjectivity particular to post-Enlightenment thought disqualifies entities like gods and spirits from serious consideration. We argue that gasses, temperatures, gods and angels can all play important roles in the origins, consequences and resolution of environmental issues. However, a practical way of conceptualising and investigating the wide variety of entities that exist is needed. To that end, we introduce the concept of ontological imaginaries and explain how this can be incorporated into research. Ontological imaginaries describe and prescribe the entities and relationships that exist for people. They recognize reality to be multiple and enacted, thus rejecting the premise of a singular and objective truth. Ontological imaginaries embody diversity, transformation and multiplicity and are therefore well equipped to capture the dynamic and often messy nature of people’s realities. By recognizing the existence and agency of gods, Tūpuna (ancestors) and everything else that exists, the concept "ontological imaginaries" can provide a tool for engaging with ontological multiplicity in environmental science.

可持续性科学关注的是谁和什么可以继续存在到未来。要做到这一点，它还必须努力解决关于目前存在什么和谁的本体论问题。尽管人们的世界中存在着截然不同的实体和关系，但在环境研究和政策中讨论的往往只是那些存在于主导的、基于科学的现实中的实体。在这种情况下，在后启蒙思想中客观性和主观性的分离使神和精神等实体失去了认真思考的资格。我们认为，气体、温度、上帝和天使都可以在环境问题的起源、后果和解决中发挥重要作用。然而，需要一种概念化和调查存在的各种实体的实用方法。为此，我们引入了本体论想象的概念，并解释了如何将其纳入研究。本体论想象描述和规定了人们存在的实体和关系。他们承认现实是多重的和制定的，从而拒绝单一和客观真理的前提。本体论想象体现了多样性、变化和多样性，因此很好地捕捉了人们现实的动态和往往混乱的本质。通过认识神、Tūpuna（祖先）和其他一切存在的事物的存在和代理，“本体论想象”概念可以为环境科学中的本体论多样性提供一个工具。
