By demonstrating the value of ecosystem services (ES), ecosystem accounting addresses the water crises by providing insights from both supply and demand perspectives. This requires ES valuation and an understanding of how valuation methods, accounting treatments, and water availability affect ES values. Using the System of Environmental-Economic Accounting (SEEA), we valued water-related ES using multiple methods, two accounting treatments, and produced monetary ES accounts for the Australian Capital Territory (ACT) to evaluate how accounting can support water pricing and management. We found that ES values varied significantly across valuation methods, accounting treatments, and water availability, ranging from AUD −10 to 998 million in the ACT. The huge range highlights the importance of selecting appropriate methods and accounting treatments when using the SEEA. Our approaches to ES valuation were: (1) ES value is embedded within economic transactions and ES value is a subset of these, and (2) ES value is unrecognised in economic transactions and proxy methods are used. Using the second approach, methods that use prices from similar markets and replacement cost extend the production boundary of the System of National Accounts (SNA) and provide additional information on economic value. Using ACT data, we demonstrate how ES valuation and accounting can be applied to current water pricing to better reflect ES use, water scarcity, and to spread costs overtime. Accounting for ES value may justify price increases to limit short-term demand, and fund catchment management activities (‘nature-based solutions’) as well as water supply infrastructure. Together, these tools and actions can mitigate the challenges of sustainably meeting water demands within socio-ecological constraints.

通过展示生态系统服务（ES）的价值，生态系统会计通过从供需角度提供见解来解决水危机。这需要对生态系统价值进行评估，并了解评估方法、会计处理和水资源供应如何影响生态系统价值。使用环境经济会计系统（SEEA），我们使用多种方法、两种会计处理对与水相关的生态系统进行了评估，并为澳大利亚首都地区（ACT）制作了货币生态系统账户，以评估会计如何支持水价和管理。我们发现ES值在评估方法、会计处理和水资源可用性方面存在显著差异，在澳大利亚首都地区从- 10澳元到9.98亿澳元不等。巨大的范围突出了在使用SEEA时选择适当方法和会计处理的重要性。我们对ES估值的方法是：(1)ES价值嵌入在经济交易中，ES价值是这些交易的一个子集，(2)ES价值在经济交易中未被确认，并使用代理方法。使用第二种方法，使用类似市场的价格和重置成本的方法扩大了国民核算体系的生产边界，并提供了关于经济价值的额外资料。利用ACT数据，我们展示了如何将生态系统估值和会计应用于当前的水价，以更好地反映生态系统的使用、水资源短缺以及分摊成本。考虑到ES价值，可以证明价格上涨是合理的，以限制短期需求，并为集水区管理活动（“基于自然的解决方案”）以及供水基础设施提供资金。总之，这些工具和行动可以减轻在社会生态约束下可持续满足水需求的挑战。

We spatially assess supply of and demand for key ecosystem services (ES) across the diverse landscapes of Savannakhet province in Laos. We used InVEST models and spatial statistics to model ES supply, and assessed ES demand by means of a survey. We analyse the spatial distribution of ES supply and demand, and identify spatial hot and cold spots of overall ES supply and ES demand, respectively. In addition, we derive synergies and trade-offs among ES. All analyses are conducted in relation to ecological zonation, socio-economic orientation, conservation efforts, and remoteness. Our results suggest that ES supply is relatively high in areas with high shares of forest and shifting cultivation systems, except the supply of the ES Food, which is relatively high in the western lowlands, with high shares of paddy rice and agriculture in general. Compared to supply, ES demand is much more evenly spread throughout the province. We identified a slight trade-off between Food and Species. Synergies were found for Water quality, Water, and Tourism. ES supply hotspots are found in less intensely used landscapes, mainly in healthy, well-functioning ecosystems, while ES supply cold spots occur near urban areas. Demand hotspots are found in all landscapes. Demand cold spots are found in urban and in remote or protected areas. ES supply increases along the ecological gradient, except for Food, which decreases. ES demand tends to decrease along the ecological gradient. ES supply varies widely by indicator and landscape type, while ES demand seems more balanced across landscapes and peoples’ socio-economic orientation. Our results underline the importance of maintaining multifunctional landscapes, which are rapidly transforming into intensely used monocultures. The baseline presented here can guide interventions to improve ES supply towards those places in Savannakhet where they might yield the best outcome in terms of satisfying land users’ demands.

本文从空间上评估了老挝萨凡那切省不同景观中关键生态系统服务（ES）的供需情况。本文采用InVEST模型和空间统计方法建立了ES供给模型，并通过调查对ES需求进行了评估。分析了生态系统供给和需求的空间分布，并分别确定了生态系统总体供给和生态系统需求的空间热点和冷点。此外，我们得出了ES之间的协同效应和权衡。所有的分析都与生态分区、社会经济导向、保护工作和偏远有关。我们的研究结果表明，在森林和轮作系统比例较高的地区，ES的供应相对较高，但在西部低地，ES食品的供应相对较高，水稻和农业的总体比例较高。与供应相比，ES的需求在全省的分布要均匀得多。我们发现了食物和物种之间的轻微权衡。发现了水质、水和旅游业的协同效应。生态系统供应热点出现在使用强度较低的景观中，主要是在健康、功能良好的生态系统中，而生态系统供应冷点则出现在城市附近。在所有景观中都发现了需求热点。需求冷点位于城市和偏远地区或保护区。ES的供给沿生态梯度增加，但食物的供给减少。ES需求沿生态梯度呈下降趋势。生态系统供应因指标和景观类型而异，而生态系统需求似乎在景观和人们的社会经济取向之间更为平衡。我们的研究结果强调了维护多功能景观的重要性，这些景观正在迅速转变为强烈使用的单一文化。这里提出的基线可以指导干预措施，以改善对萨凡纳赫特那些可能在满足土地使用者需求方面产生最佳结果的地方的ES供应。

This research aims to model and map flows of ecosystem contributions to society across distances and spatial scales in a marine social-ecological system (SES). We spatially assess Ecosystem Service (ES) flows from small-scale fisheries by considering environmental costs and benefits emerging across the fisheries supply chain, and by investigating the role and contributions of intermediaries from the point of supply up to reception of the final benefit. While the existing literature on fisheries SES has predominantly focused on either the supply or demand side, in limited cases researchers examine flows by considering their spatial attributes across different spatial scales. We address this gap by defining benefit flows within the fisheries SES through the development of an ES flow index, integrating socioeconomic and environmental system attributes. Also, geographical accessibility is embedded in the index to account for access to resources, i.e. the ability to benefit from things. ES flow is assessed through plural costs and benefits emerging across intermediate activities of the supply chain. Costs are assessed as carbon emissions from catching, processing, and transportation, while benefits are those accruing to beneficiaries through nutritional benefits to jobs generated. All data and the final index are developed in a spatially explicit manner which allows for visualizing the flow of ES to both adjacent and distant to the supplying ecosystem, beneficiaries. The maps reveal distinct patterns for coastal regions compared to the regions that receive benefits away from the coast, indicating a spatial variability with a dependence on the distance from the providing ecosystem. The results of the study have implications for understanding how access to marine natural resources can impact regional beneficiaries, while revealing potential ES supply-flow and flow-demand mismatches in the distribution of marine resources, particularly in areas with communities in need and limited infrastructure.

本研究旨在建立海洋社会-生态系统（SES）中不同距离和空间尺度的生态系统对社会贡献流的模型和地图。我们通过考虑整个渔业供应链中出现的环境成本和效益，并通过调查从供应点到最终收益的中介机构的作用和贡献，在空间上评估了小规模渔业的生态系统服务（ES）流动。虽然现有的渔业SES文献主要集中在供给或需求方面，但在有限的情况下，研究人员通过考虑不同空间尺度的空间属性来研究流量。我们通过制定综合社会经济和环境系统属性的社会经济系统流量指数来定义渔业社会经济系统内的利益流动，从而解决了这一差距。此外，地理可及性被嵌入到索引中，以说明获取资源的能力，即从事物中受益的能力。通过供应链中间活动中出现的多重成本和收益来评估ES流。成本被评估为捕捞、加工和运输过程中的碳排放，而收益则是通过营养效益和创造的就业机会给受益人带来的收益。所有数据和最终指数都以空间明确的方式开发，从而可以可视化ES流向邻近和远离供应生态系统的受益者。与远离海岸的地区相比，这些地图揭示了沿海地区的不同模式，表明了与提供生态系统的距离相关的空间变异性。这项研究的结果有助于理解获取海洋自然资源如何影响区域受益者，同时揭示海洋资源分布中潜在的ES供需不匹配，特别是在有需求的社区和基础设施有限的地区。

Cultural ecosystem services (CES) represent intangible values, making them inherently challenging to analyze. In this study, we present a framework that combines web scraping, text mining, and statistical analysis to gain deeper insights into how people perceive valuable ecosystems and the benefits they derive from them. A total of 4,760 public reviews were collected from the Google Maps platform using dynamic web scraping techniques. Machine learning-based topic modelling was then applied to identify key themes related to CES in selected national parks and protected areas across the Czech Republic. Finally, we tested the hypothesis that the relative frequency of specific topics varies significantly between locations. The proposed approach proved effective in the automated evaluation of CES and in highlighting the distinctive features of the studied sites.

文化生态系统服务（CES）代表着无形的价值，这使得分析它们具有固有的挑战性。在这项研究中，我们提出了一个结合网络抓取、文本挖掘和统计分析的框架，以更深入地了解人们如何看待有价值的生态系统以及他们从中获得的好处。谷歌地图平台使用动态网页抓取技术共收集了4760条公众评论。然后应用基于机器学习的主题建模来确定捷克共和国选定的国家公园和保护区中与CES相关的关键主题。最后，我们检验了特定主题的相对频率在不同地点之间有显著差异的假设。所建议的方法在自动评价生态环境和突出所研究地点的独特特征方面证明是有效的。

Sustainable and just environmental management depends on meaningful consideration of the plural values of nature, as they arise in association with diverse worldviews and understandings of well-being. To achieve value pluralism in decision-making, we must also attend to knowledge pluralism, in terms of recognizing the validity and decision relevance of a broader suite of knowledge forms that convey diverse understandings of well-being and benefit. In this article, we outline a social learning tool – the Benefits Knowledges Learning Framework – that supports expanded thinking about decision-relevant, actionable knowledge, and the associated spectrum of available opportunities to learn from these diverse knowledge forms across phases of decision-making. It does so through: 1) cultivation of reflexivity and mutual learning about the knowledge systems of diverse actors involved in the decision process; 2) identification of diverse benefits knowledge forms that are available to inform decision-making; and 3) identification of opportunities to learn from these knowledge forms. Diverse forms of benefits knowledge include both knowledge products (documentation) and knowledge practices (lived and embodied). The framework can be applied to retrospective case analysis to understand and learn from constraints and enabling factors in past decision processes. It can also be applied to assess on-going decision-making and identify current opportunities for improvement. The framework begins with a start-up phase that encourages those applying the framework to address any concerns raised by stakeholders and rightsholders and determine whether framework application is appropriate in a particular context.

可持续和公正的环境管理取决于有意义地考虑自然的多元价值，因为它们与不同的世界观和对福祉的理解有关。为了实现决策中的价值多元化，我们还必须关注知识多元化，即认识到传达对福祉和利益的不同理解的更广泛的知识形式的有效性和决策相关性。在本文中，我们概述了一种社会学习工具——利益知识学习框架，它支持对决策相关的、可操作的知识的扩展思考，以及相关的可用机会，以便在决策的各个阶段从这些不同的知识形式中学习。它通过：1)培养反身性和相互学习参与决策过程的不同行动者的知识系统；2)识别可用于决策的各种利益知识形式；3)识别从这些知识形式中学习的机会。各种形式的利益知识包括知识产品（文档）和知识实践（生活和具体化）。该框架可以应用于回顾性案例分析，以理解和学习过去决策过程中的制约因素和使能因素。它也可用于评价正在进行的决策和确定当前的改进机会。该框架从启动阶段开始，该阶段鼓励应用该框架的人解决利益相关方和权利持有人提出的任何问题，并确定框架应用是否适用于特定环境。

This article examines the longstanding conflict between the Mapuche people and the forestry industry in Chile through a dual framework of Environmental Justice (EJ) and historical analysis. By situating recognition, procedural, and distributive justice within the context of colonial legacies, we highlight how ahistorical EJ approaches fail to address socio-environmental trade-offs in settler colonial contexts. Our fieldwork, which included interviews and observations in Mapuche communities affected by forestry, reveals contrasting perceptions of ecosystem services (ES) among stakeholders. While forestry companies prioritize provisioning services like timber production, Mapuche communities emphasize relational values tied to native forests, such as spiritual fulfillment and cultural heritage preservation. These divergences underscore systemic recognition injustices and procedural exclusions that perpetuate distributive inequities. We argue that meaningful engagement with Indigenous knowledge and histories is crucial for fostering equitable ES governance. By integrating EJ perspectives into ES frameworks, our study contributes to the decolonization of ES research and offers insights into resolving socio-ecological conflicts in Indigenous territories.

本文通过环境正义（EJ）和历史分析的双重框架考察了智利马普切人与林业之间的长期冲突。通过在殖民遗产的背景下定位承认，程序和分配正义，我们强调了非历史的EJ方法如何未能解决定居者殖民背景下的社会环境权衡。我们的实地调查，包括对受林业影响的马普切社区的访谈和观察，揭示了利益相关者对生态系统服务（ES）的不同看法。虽然林业公司优先考虑提供木材生产等服务，但马普切社区强调与原始森林有关的关系价值，如精神满足和文化遗产保护。这些分歧强调了使分配不平等永久化的系统性认识不公和程序性排斥。我们认为，有意义地参与土著知识和历史对于促进公平的ES治理至关重要。通过将EJ观点整合到ES框架中，我们的研究有助于ES研究的非殖民化，并为解决土著地区的社会生态冲突提供见解。

In recent years, the shrinkage of terminal lakes in Central Asia has triggered environmental degradation and disrupted the supply of critical ecosystem services (ES). Understanding the tradeoffs and synergies among ES in these basins is essential for promoting sustainable regional development and enhancing ecological resilience. This study quantified the spatiotemporal dynamics of five major ES: soil conservation, sand fixation, water yield, carbon storage, and habitat quality using process-based ecosystem models. A Bayesian Network model was constructed to disentangle the effects of natural and anthropogenic influences on ES and identify their dominant drivers. To further characterise ES interactions, we developed a directional tradeoff/synergy strength index that captures both the intensity and directionality of inter-ES relationships. The results revealed spatially heterogeneous tradeoff patterns, with certain ES pairs exhibiting strong conflicts despite sharing similar drivers. Scenario-based optimisation highlighted regional differences in ES priorities, for instance, balancing carbon storage and water yield in the Amu Darya Basin, and managing the interplay of sand fixation, water yield, and soil conservation in the Ili River Basin. These findings provide a decision-support basis for targeted ecosystem management in arid terminal lake regions.

近年来，中亚末端湖泊的萎缩引发了环境退化，并扰乱了关键生态系统服务（ES）的供应。了解这些流域生态系统之间的权衡和协同作用对于促进区域可持续发展和增强生态复原力至关重要。本研究采用基于过程的生态系统模型，量化了土壤保持、固沙、水量、碳储量和生境质量5个主要生态系统的时空动态。构建贝叶斯网络模型，理清自然和人为影响对ES的影响，并确定其主导驱动因素。为了进一步表征ES相互作用，我们开发了一个定向权衡/协同强度指数，该指数可以捕捉ES内部关系的强度和方向性。结果显示了空间异质性的权衡模式，尽管共享相似的驱动因素，但某些ES对表现出强烈的冲突。基于场景的优化突出了生态系统优先事项的区域差异，例如阿姆河流域的碳储量和水量平衡，以及伊犁河流域固沙、水量和土壤保持的相互作用管理。研究结果可为干旱末端湖区生态系统定向管理提供决策支持依据。

River deltas around the world have experienced ecological decline due to upstream development and human activities. However, assessing the monetized benefits of ecosystem restoration is challenging due to the less tangible nature of many values that people hold for these natural areas. This paper quantifies the non-use values for river delta ecological conservation using a stated preference survey. The empirical application is the Saskatchewan River Delta in Canada where we develop and administer a national survey to elicit people’s preferences for restoration scenarios with changing fish and wildlife population levels and changes in the extent of habitat in good ecological condition. We find that Canadians are willing to pay for river delta restoration improvements, and preferences for restoration options are heterogeneous across the population. Models with nonlinear attribute levels fit the choice data better than linear attribute specifications suggesting the presence of diminishing marginal willingness to pay as ecological improvements increase. The annual monetized benefits for Saskatchewan River Delta future scenarios are estimated to be $79 to $223 per household depending on the level of restoration efforts. This study contributes to the empirical evidence that the benefits of nature accrue to people that live far away from natural areas.

由于上游开发和人类活动，世界各地的河流三角洲都经历了生态衰退。然而，评估生态系统恢复的货币化效益是具有挑战性的，因为人们对这些自然区域持有的许多价值不太有形。本文采用陈述偏好调查方法量化了河流三角洲生态保护的非利用价值。我们以加拿大萨斯喀彻温河三角洲为研究对象，开展并管理了一项全国性调查，以了解人们对鱼类和野生动物种群水平变化以及良好生态条件下栖息地范围变化的恢复方案的偏好。我们发现，加拿大人愿意为河流三角洲的修复改善支付费用，并且不同人群对修复方案的偏好存在差异。具有非线性属性水平的模型比线性属性规范更适合选择数据，这表明随着生态改善的增加，边际支付意愿存在递减。萨斯喀彻温河三角洲未来的年度货币化收益估计为每户79至223美元，具体取决于恢复工作的水平。这项研究提供了经验证据，证明远离自然地区的人也能从自然中受益。

For decades, China has been suffering from frequent typhoon strikes. To protect population and property in coastal areas from typhoon-induced losses, wetlands are of great importance. Wetlands mitigate the impact of typhoons by surge energy absorption and flood regulation. However, currently there are only a few comprehensive studies on the protection value of intertidal and inland wetlands against typhoons. In this study, we used two economic regression models to evaluate 92 typhoon cases that occurred in China from 2000 to 2020 and the economic losses they caused. The results indicate that both intertidal and inland wetlands can effectively reduce the economic losses. In addition, we compared the typhoon protection value of intertidal wetlands with that of inland ones. The results show that the average marginal values of intertidal and inland wetlands against typhoons are respectively CNY 23.652 million/km² and 1.261 million/km² (with median values of CNY 10.537 million/km² and 0.605 million/km², respectively). We also analyzed the typhoon protection value of wetlands at the city level. Although inland wetlands provide relatively lower value compared to intertidal wetlands, they still play an important role in mitigating the economic losses caused by typhoons and thus should not be overlooked. Wetland conservation is not only a cost-effective way to largely reduce typhoons damage, but also provides many other valuable ecosystem services.

几十年来，中国一直遭受频繁的台风袭击。为了保护沿海地区的人口和财产免受台风造成的损失，湿地是非常重要的。湿地通过吸收潮涌能量和调节洪水来减轻台风的影响。然而，目前关于潮间带和内陆湿地对台风的保护价值的综合研究还很少。本研究采用两种经济回归模型对2000 ~ 2020年中国发生的92次台风及其造成的经济损失进行了评估。结果表明，潮间带湿地和内陆湿地都能有效减少经济损失。此外，我们还比较了潮间带湿地与内陆湿地的防台风价值。结果表明：潮间带和内陆湿地对台风的平均边际值分别为2365.2万元/km2和126.1万元/km2（中位数分别为1053.7万元/km2和600.5万元/km2）；分析了城市湿地的防台风价值。与潮间带湿地相比，内陆湿地的价值相对较低，但在减轻台风造成的经济损失方面仍发挥着重要作用，不容忽视。保护湿地不仅是一种经济有效的方法，大大减少台风的破坏，而且还提供许多其他有价值的生态系统服务。

Horizontal ecological compensation (HEC) offers many advantages over vertical ecological compensation by reducing government financial burdens, effectively addressing positive externalities and ecosystem service spillover effects, and fostering harmonious relations between upstream and downstream communities. However, a lack of reliable data remains a significant obstacle to its implementation. This study employs the InVEST model, the CASA model, the RWEQ model, and related statistical methods. Additionally, the Breaking Point Model and Field Strength Theory are used to assess eight key ecosystem services and their spillover effects at different spatial scales, with the aim of informing cost-benefit sharing and HEC mechanisms in and around the Qilian Mountains, China. Our results suggest that: (1) Soil conservation contributes the most to ecosystem services, accounting for 47.26%, followed by water retention (17.52%) and carbon sequestration (15.62%). (2) Forests (48.51%) and grasslands (39.22%) are the primary ecosystem types providing these services. (3) The ecosystem services exhibit significant internal coupling, peripheral coupling, and tele-coupling, creating spillovers at watershed, provincial, and even global scales. (4) In terms of the scope of the spillover effect, tourism and leisure lead, followed by sandstorm prevention, material production, water retention, soil conservation, flood regulation, carbon sequestration, and pollination services. From these data, we also constructed three HEC pathways: intra-provincial watersheds, inter-provincial HEC, and international HEC. Our findings are useful for developing a fair and well-functioning HEC mechanism that offers multiple environmental and social benefits, contributing to the realization of several UN Sustainable Development Goals (SGDs) such as eliminating poverty (#1), zero hunger (#2), climate action (#13), and life on land (#15).

横向生态补偿在减轻政府财政负担、有效解决正外部性和生态系统服务溢出效应、促进上下游社区和谐关系等方面具有纵向生态补偿的诸多优势。然而，缺乏可靠的数据仍然是实施该计划的一个重大障碍。本研究采用InVEST模型、CASA模型、RWEQ模型及相关统计方法。此外，利用断点模型和场强理论对祁连山及其周边地区8种关键生态系统服务功能及其在不同空间尺度上的溢出效应进行了评估，旨在为祁连山及其周边地区的成本效益分享和HEC机制提供信息。结果表明：(1)土壤保持对生态系统服务的贡献最大，占47.26%，其次是保水（17.52%）和固碳（15.62%）。(2)森林（48.51%）和草地（39.22%）是提供这些服务的主要生态系统类型。(3)生态系统服务具有显著的内部耦合、外围耦合和远程耦合，在流域、省乃至全球尺度上产生溢出效应。(4)从外溢效应的范围来看，旅游休闲的外溢效应最大，其次是防沙、物资生产、保水、保土、防洪、固碳和授粉服务。根据这些数据，我们还构建了三条高输商路径：省内流域、省间高输商和国际高输商。我们的研究结果有助于建立一个公平和运作良好的HEC机制，提供多种环境和社会效益，有助于实现几个联合国可持续发展目标（SGDs），如消除贫困（#1）、零饥饿（#2）、气候行动（#13）和陆地生命（#15）。
