The study examines the governance of low trophic species mariculture (LTM) using Sweden as a case study. LTM, involving species such as seaweeds and mollusks, offers ecosystem services and nutritious foods. Despite its potential to contribute to blue growth and Sustainable Development Goals, LTM development in the EU and OECD countries has stagnated. A framework for mapping governance elements (institutions, structures, and processes) and analyzing governance objective (effective, equitable, responsive, and robust) was combined with surveys addressed to the private entrepreneurs in the sector. Analysis reveals ineffective institutions due to lack of updated legislation and guidance, resulting in ambiguous interpretations. Governance structures include multiple decision-making bodies without a clear coordination agency. Licensing processes were lengthy and costly for the private entrepreneurs, and the outcomes were uncertain. To support Sweden’s blue bioeconomy, LTM governance requires policy integration, clearer direction, coordinated decision-making, and mechanisms for conflict resolution and learning.

本研究以瑞典为例,探讨了低营养级物种海产养殖(LTM)的管理问题。低营养物种海产养殖涉及海藻和软体动物等物种,可提供生态系统服务和营养食品。尽管低温海产养殖具有促进蓝色增长和可持续发展目标的潜力,但欧盟和经合组织国家的低温海产养殖发展却停滞不前。绘制治理要素(机构、结构和流程)和分析治理目标(有效、公平、反应迅速和稳健)的框架与针对该行业私营企业家的调查相结合。分析表明,由于缺乏最新立法和指导,机构效率低下,导致解释含糊不清。治理结构包括多个决策机构,但没有明确的协调机构。对私营企业家而言,许可程序冗长且成本高昂,结果也不确定。为支持瑞典的蓝色生物经济,LTM 治理需要政策整合、更明确的方向、协调的决策以及解决冲突和学习的机制。

Climate concern is on the rise in many countries and recent research finds that lifestyle- and behaviour-change could advance climate action; yet, individuals struggle to move their climate concern into action. This is known as the ‘awareness-action inconsistency,’ ‘psychological climate paradox,’ or ‘values-action gap.’ While this gap has been extensively studied, climate action implementation and policy-design seldom sufficiently apply that body of knowledge in practice. This Perspective presents a comprehensive heuristic to account for how individuals bring climate change into their awareness (climate action-logics), how they keep climate change out of their awareness (climate shadow), how social narratives contribute to shaping choices (climate discourses), and how systems and structures influence and constrain agency (climate-action systems). The heuristic is illustrated with an example of 15-Minute Cities in Canada. Understanding the multifaceted dilemma that weighs on people’s sense-making and behaviours may help policy-makers and practitioners to ameliorate the climate awareness-action gap.

最近的研究发现,改变生活方式和行为可以推动气候行动;然而,个人却很难将对气候的关注转化为行动。这就是所谓的 "认识-行动不一致"、"心理气候悖论 "或 "价值观-行动差距"。虽然人们对这一差距进行了广泛研究,但气候行动的实施和政策设计却很少在实践中充分应用这些知识。本视角提出了一个全面的启发式方法,以解释个人如何将气候变化纳入自己的意识(气候行动逻辑),如何使气候变化远离自己的意识(气候阴影),社会叙事如何有助于形成选择(气候话语),以及系统和结构如何影响和制约机构(气候行动系统)。我们以加拿大的 "15 分钟城市 "为例,对启发式方法进行了说明。了解影响人们意识形成和行为的多方面困境有助于政策制定者和实践者改善气候意识与行动之间的差距。

The EU Nature Restoration Law (NRL) is critical for the restoration of degraded ecosystems and active afforestation of degraded peatlands has been suggested as a restoration measure under the NRL. Here, we discuss the current state of scientific evidence on the climate mitigation effects of peatlands under forestry. Afforestation of drained peatlands without restoring their hydrology does not fully restore ecosystem functions. Evidence on long-term climate benefits is lacking and it is unclear whether CO2 sequestration of forest on drained peatland can offset the carbon loss from the peat over the long-term. While afforestation may offer short-term gains in certain cases, it compromises the sustainability of peatland carbon storage. Thus, active afforestation of drained peatlands is not a viable option for climate mitigation under the EU Nature Restoration Law and might even impede future rewetting/restoration efforts. Instead, restoring hydrological conditions through rewetting is crucial for effective peatland restoration.

欧盟《自然恢复法》(NRL)对于恢复退化的生态系统至关重要,而根据《自然恢复法》,退化泥炭地的积极植树造林被建议作为一项恢复措施。在此,我们将讨论有关林业下泥炭地气候减缓效应的科学证据现状。在不恢复水文的情况下对排水泥炭地进行植树造林并不能完全恢复生态系统功能。目前还缺乏有关长期气候效益的证据,也不清楚排水泥炭地上的森林二氧化碳固存能否长期抵消泥炭的碳损失。虽然在某些情况下植树造林可能会带来短期收益,但它会损害泥炭地碳储存的可持续性。因此,根据《欧盟自然恢复法》,在干涸泥炭地积极植树造林并不是一个可行的气候减缓方案,甚至可能会阻碍未来的复湿/恢复工作。相反,通过复湿恢复水文条件对于有效恢复泥炭地至关重要。

Sustainable livestock management plays a crucial role in food production, climate change mitigation, and cultural preservation. Our study aimed to identify and analyse the diversity of social–ecological conditions that characterize extensive livestock systems in southern Patagonia. We integrated data collected from interviews and secondary sources and analysed data using hierarchical cluster analysis and non-metric multidimensional scaling to identify distinct ranching types. A qualitative analysis of key informant interviews identified key social–ecological changes for each type. The results emphasize the impact of administration, production, and biophysical factors on shaping different livestock ranching schemes. Further, we identified three significant social–ecological changes driving the dynamics of these systems, including shifts from (1) sheep to cattle ranching, (2) domestic to feral cattle ranching, and (3) landowners to tenant land managers. These findings have implications for policymakers seeking to develop strategies tailored to diverse realities, ensuring the sustainability of livestock systems in Tierra del Fuego.

可持续牲畜管理在粮食生产、减缓气候变化和文化保护方面发挥着至关重要的作用。我们的研究旨在确定和分析巴塔哥尼亚南部广泛畜牧系统所特有的社会生态条件的多样性。我们整合了从访谈和二手资料中收集到的数据,并使用分层聚类分析和非度量多维标度对数据进行了分析,以确定不同的牧场类型。通过对主要信息提供者访谈的定性分析,确定了每种类型的主要社会生态变化。结果强调了行政、生产和生物物理因素对形成不同畜牧业计划的影响。此外,我们还发现了推动这些系统动态发展的三个重要的社会生态变化,包括从(1)牧羊到牧牛,(2)家畜放牧到野牛放牧,以及(3)土地所有者到佃户土地管理者的转变。这些发现对决策者制定适合不同现实情况的战略,确保火地岛畜牧系统的可持续性具有重要意义。

With a global footprint of 10 million hectares across 12.5 million farms, coffee is among the world’s most traded commodities. The coffee industry has launched a variety of initiatives designed to reduce coffee’s contribution to climate change and biodiversity loss and enhance the socio-economic conditions of coffee producers. We systematically reviewed the literature on the sustainability and governance of coffee production and developed a typology of eleven sustainability initiatives. Our review shows that coffee sustainability research has focused primarily on the economic outcomes of certification schemes. The typology expands our knowledge of novel sustainability initiatives being led by coffee farming communities themselves, allowing for an improved consideration of power dynamics in sustainability governance. Sustainability initiatives governed by local actors can improve sustainability outcomes by empowering local decision makers to assess direct risks and benefits of sustainable practices to the local environment, economy, and culture.

咖啡的全球足迹遍布 1,000 万公顷、1,250 万个农场,是世界上交易量最大的商品之一。咖啡业发起了各种倡议,旨在减少咖啡对气候变化和生物多样性丧失的影响,并改善咖啡生产者的社会经济条件。我们系统回顾了有关咖啡生产可持续性和管理的文献,并对 11 项可持续性倡议进行了分类。我们的回顾表明,咖啡可持续性研究主要集中在认证计划的经济成果上。该类型学扩展了我们对咖啡种植社区自身领导的新型可持续发展倡议的了解,从而能够更好地考虑可持续发展治理中的权力动态。由当地行动者管理的可持续发展倡议可以增强当地决策者的能力,评估可持续发展实践对当地环境、经济和文化带来的直接风险和益处,从而改善可持续发展成果。

When enough is enough: Introducing sufficiency corridors to put techno-economism in its place 当 "够了 "的时候:引入 "充足走廊",让技术经济学占据一席之地

Today's ecological crises are entwined with inequality dynamics, yet prevailing techno-economic approaches in climate research and policy fall short in addressing the ecological crisis as distributional crisis. Recognising the limitations of techno-economism, focused on markets (price adjustments) and technology (efficiency gains), this contribution introduces sufficiency corridors as a concept, research field, and policy approach. Sufficiency corridors represent the space between a floor of meeting needs and a ceiling of ungeneralisable excess, i.e. within the sufficiency corridor everyone has enough (to satisfy needs) while no one has too much (to endanger planetary boundaries and need satisfaction). Establishing such corridors entails a process over time that continuously narrows the gap between floors and ceilings, lifting the former and pushing down the latter by strengthening forms of consumption and production that contribute to need satisfaction while shrinking those that do not. The article discusses the profound implications of this approach for how societal reality is reproduced and/or changed, highlighting the need for decisions that eliminate options between and within sectors and in the realms of consumption and production. After addressing questions of decision-making and the potential to realise corridors, the contribution concludes that the growing scientific consensus to complement techno-economic approaches with sufficiency measures remains inadequate. Instead, the possibility of a transformation by design hinges on embedding techno-economism within and subordinating it to a sufficiency framework.

当今的生态危机与不平等动态交织在一起,但气候研究和政策中普遍采用的技术经济学方法却无法解决作为分配危机的生态危机。认识到以市场(价格调整)和技术(效率增益)为重点的技术经济学的局限性,本文介绍了作为一种概念、研究领域和政策方法的自给自足走廊。充足走廊代表了满足需求的底线和不可通用的过剩上限之间的空间,也就是说,在充足走廊内,每个人都有足够的东西(满足需求),而没有人拥有太多(危及地球边界和需求满足)。建立这样的走廊需要一个过程,这个过程会随着时间的推移不断缩小底线和上限之间的差距,通过加强有助于满足需求的消费和生产形式,同时缩小无助于满足需求的消费和生产形式,从而抬高前者,压低后者。文章讨论了这一方法对如何再现和/或改变社会现实的深远影响,强调了在部门之间和部门内部以及在消费和生产领域做出消除选择的决策的必要性。在讨论了决策问题和实现走廊的潜力之后,文章得出结论认为,科学界日益达成的共识,即以充足性措施来补充技术经济方法,仍然是不够的。相反,设计转型的可能性取决于将技术经济学纳入充足性框架并使其从属于该框架。

This study focuses on the Skalička Waterwork (SWW), a largely debated and media-covered water-related/flood-protection project in the Czech Republic. Relying primarily on stakeholder interviews, we traced back and reconstructed the project’s development, including its key tipping points reflecting the changing societal preferences for particular measures, yet also the involvement of individual actors/stakeholders, and their differing views. The case eventually crystallized into the “dam versus polder” dispute; concerned by the repercussions for the local landscape, a joint initiative of NGOs, local activists, and politicians not only opposed the dam variant proposed by the state river basin administration but also succeeded in pushing through the alternative scheme of side dry polder. While in many ways specific (e.g. not entailing local resistance), the case exemplifies recent shifts (and respective struggles) within flood risk management, including the increasing importance attributed to complex, catchment-wide perspectives, joint local and scientific knowledge, participatory decision-making processes, or implementation of nature-based and hybrid solutions.

本研究的重点是捷克共和国的斯卡利奇卡水利工程(SWW),这是一个在很大程度上引起争议并被媒体报道的与水有关的/洪水保护项目。主要通过对利益相关者的访谈,我们追溯并重构了该项目的发展过程,包括其关键转折点,反映了社会对特定措施的偏好不断变化,同时也反映了个别参与者/利益相关者的参与及其不同观点。该案例最终演变成了 "大坝与围垦 "之争;非政府组织、当地活动家和政治家出于对当地景观影响的考虑,发起了一项联合行动,不仅反对州河流流域管理部门提出的大坝方案,还成功地推动了侧干围垦的替代方案。虽然该案例在许多方面都具有特殊性(如不涉及当地的抵制),但它体现了近期洪水风险管理的转变(以及各自的斗争),包括日益重视复杂的全流域视角、当地与科学知识的结合、参与式决策过程或基于自然的混合解决方案的实施。

While in many ways specific (e.g. not entailing local resistance), the case exemplifies recent shifts (and respective struggles) within flood risk management, including the increasing importance attributed to complex, catchment-wide perspectives, joint local and scientific knowledge, participatory decision-making processes, or implementation of nature-based and hybrid solutions.</p></div>","PeriodicalId":461,"journal":{"name":"Ambio","volume":"53 10","pages":""},"PeriodicalIF":5.8,"publicationDate":"2024-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13280-024-02022-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140804185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Expanding in both scope and scale, ecosystem restoration needs to embrace complex social–ecological dynamics. To help scientists and practitioners navigate ever new demands on restoration, we propose the “social–ecological ladder of restoration ambition” as a conceptual model to approach dynamically shifting social and ecological restoration goals. The model focuses on three dynamic aspects of restoration, namely degrading processes, restoration goals and remedial actions. As these three change through time, new reinforcing and balancing feedback mechanisms characterize the restoration process. We illustrate our model through case studies in which restoration has become increasingly ambitious through time, namely forest landscape restoration in Rwanda and grassland restoration in Germany. The ladder of restoration ambition offers a new way of applying social–ecological systems thinking to ecosystem restoration. Additionally, it raises awareness of social–ecological trade-offs, power imbalances and conflicting goals in restoration projects, thereby laying an important foundation for finding more practicable and fairer solutions.

生态系统恢复的范围和规模都在不断扩大,需要考虑复杂的社会生态动态。为了帮助科学家和实践者把握对恢复工作提出的新要求,我们提出了 "社会-生态恢复雄心阶梯 "这一概念模型,用于实现动态变化的社会和生态恢复目标。该模型侧重于恢复的三个动态方面,即退化过程、恢复目标和补救行动。随着时间的推移,这三个方面会发生变化,新的强化和平衡反馈机制会成为恢复过程的特征。我们通过案例研究(卢旺达的森林景观恢复和德国的草地恢复)来说明我们的模型,在这些案例研究中,恢复的雄心随着时间的推移变得越来越大。恢复雄心的阶梯提供了一种将社会生态系统思维应用于生态系统恢复的新方法。此外,它还提高了人们对恢复项目中的社会-生态权衡、权力失衡和目标冲突的认识,从而为找到更实用、更公平的解决方案奠定了重要基础。

Protected areas (PAs) are effective in mitigating human pressures, yet their future pressure alleviating effects remain unclear. In this study, we employed the ConvLSTM model to forecast the future human footprint and analyzed human pressure trends using Theil–Sen median and Mann–Kendall tests. We further evaluated the mitigating effects of PAs within their buffer zones (1–10 km) and the contributions of different IUCN categories of PAs to mitigating human pressure using linear regression models. The results indicate that by 2035, the average human pressure value is expected to increase by 11%, with trends exhibiting a polarized pattern. Furthermore, PAs also effectively mitigate human pressure within their 1 km buffer zones. Different categories of PAs vary in their effectiveness in mitigating human pressure, and stricter conservation areas are not always the most effective. This study can offer insights for evaluating the effectiveness of PAs in reducing human pressure and advocate for their targeted management in urban areas.

保护区(PA)能有效缓解人类压力,但其未来的压力缓解效果仍不明确。在本研究中,我们采用 ConvLSTM 模型预测了未来的人类足迹,并利用 Theil-Sen 中位数和 Mann-Kendall 检验分析了人类压力趋势。我们还利用线性回归模型进一步评估了保护区缓冲区(1-10 公里)内的缓解作用以及世界自然保护联盟(IUCN)不同类别保护区对缓解人类压力的贡献。结果表明,到 2035 年,人类压力的平均值预计将增加 11%,并呈现两极化趋势。此外,保护区还能有效缓解其 1 公里缓冲区内的人类压力。不同类别的保护区在缓解人类压力方面的效果各不相同,更严格的保护区并不总是最有效的。本研究可为评估保护区在减轻人类压力方面的成效提供启示,并倡导在城市地区对保护区进行有针对性的管理。
