Terraces are a unique type of agro-ecosystem that are vital for regional food security, biodiversity, and the provision of cultural ecosystem services (CES) to society. This study introduces a novel approach to map the supply–demand balance of terrace CES (TCES) in China by integrating geo-data and social media images. Firstly, a TCES supply assessment framework is developed, comprising scenic attractiveness and heritage attractiveness, to assess TCES supply. Secondly, based on 55,616 geotagged Weibo images, the EfficientNet model classifies images into seven categories, with a questionnaire linking these to four CES types: aesthetic services, heritage & cultural services, recreation & tourism services, and spiritual & emotional services. Population data is also used to assess TCES demand. Finally, the supply–demand ratio and bivariate Moran’s I examine the balance and spatial autocorrelation of TCES. The results show: 1) High supply areas are mainly in southern China, while demand is more scattered in several hotspots; 2) There is a significant positive spatial autocorrelation between supply and demand, where higher supply promotes greater demand. High CES supply and demand cluster in Zhejiang-Fujian Hills and Yunnan-Guizhou Plateau, with imbalances occurring in metropolitan areas or mountainous areas along provincial boundaries. These findings and methodologies provide valuable insights for the planning and management of terraces in China, as well as for future CES-related studies.

梯田是一种独特的农业生态系统，对区域粮食安全、生物多样性和向社会提供文化生态系统服务（CES）至关重要。本研究提出了一种整合地理数据和社交媒体图像来绘制中国梯田消费空间供需平衡的新方法。首先，构建由景区吸引力和遗产吸引力组成的TCES供应评估框架，对TCES供应进行评估。其次，基于55,616张带有地理标签的微博图片，effentnet模型将图片分为七类，并通过问卷将这些图片与四种CES类型联系起来：美学服务、遗产与文化服务、娱乐与旅游服务和精神与情感服务。人口数据也用于评估TCES的需求。最后，利用供需比和双变量Moran’s分析了TCES的平衡性和空间自相关性。结果表明：1)供给高的地区主要集中在南方，需求较分散在几个热点地区；②供给与需求之间存在显著的空间自相关关系，供给越大，需求越大。消费电子产品的高供给和高需求集中在浙闽丘陵和云贵高原，失衡主要发生在省会地区或省际山区。这些发现和方法为中国梯田的规划和管理以及未来的ces相关研究提供了有价值的见解。

Africa is home to eleven species of vultures, seven of which face the risk of extinction and are listed as Vulnerable, Endangered or Critically endangered on the IUCN Red List. The major threats are poisoning, belief-based use, electrocutions and collisions. The loss of vultures in Asia provided a window into a catastrophic scenario without vultures and the impact of the loss of the ecosystem services they provide. In the African context, there is a knowledge gap on the importance of vultures to humans and the impact that a loss of vultures would have. This paper attempts to fill this gap with an economic valuation of the ecosystem services provided by vultures in Southern Africa, with a focus on Botswana, Zambia and Zimbabwe. The ecosystem services addressed in the assessment include provisioning, regulating and cultural services. Data were collected through four surveys targeting different beneficiary groups: 1. local communities in the Kavango Zambezi Transfrontier Conservation Area; 2. the general public within each country; 3. the international public; and 4. rangers and park managers. A mix of valuation methods were used including discrete choice experiments, contingent valuation, avoided damage costs, replacement costs, and net factor income. The total economic value of ecosystem services in the three countries is estimated to be just over USD 250 million per year. This is largely attributed to existence and bequest values and the sanitation and pest control service provided by vultures. Although vultures are arguably not as charismatic as other species of interest in the continent, their conservation is highly important to the welfare and health of people in Southern Africa.

非洲是11种秃鹫的家园，其中7种面临灭绝的危险，被列为世界自然保护联盟红色名录中的易危、濒危或极度濒危物种。主要的威胁是中毒、基于信仰的使用、触电和碰撞。秃鹫在亚洲的消失提供了一个窗口，让我们看到没有秃鹫的灾难性情景，以及它们提供的生态系统服务丧失的影响。在非洲的背景下，人们对秃鹫对人类的重要性以及秃鹫的消失所带来的影响还存在知识缺口。本文试图通过对南部非洲秃鹫提供的生态系统服务的经济评估来填补这一空白，重点是博茨瓦纳、赞比亚和津巴布韦。评估中涉及的生态系统服务包括供应、调节和文化服务。通过针对不同受益群体的四项调查收集数据：卡万戈赞比西跨境保护区的当地社区；2. 民众：每个国家的普通民众；3. 国际公众；和4。护林员和公园管理员。我们使用了多种评估方法，包括离散选择实验、或有评估、避免损害成本、重置成本和净要素收入。据估计，这三个国家生态系统服务的总经济价值每年略高于2.5亿美元。这在很大程度上归因于秃鹰的生存和遗产价值，以及秃鹰提供的卫生和虫害防治服务。尽管秃鹫不像非洲大陆上的其他物种那样有魅力，但它们的保护对南部非洲人民的福利和健康非常重要。

Nature in cities is essential for human well-being. Quantifying and valuing the goods and services provided by nature to city dwellers is missing in tropical contexts. Yet, as cities worldwide face similar challenges, understanding the services provided by tropical urban ecosystems becomes imperative for effective management. Here, we present the first Natural Capital Assessment of a tropical city, unveiling three critical insights. Firstly, we demonstrate the vital reliance of a developed tropical city on nature, particularly for climate change mitigation through regulating services. Secondly, we identify intact natural areas as Singapore’s most valuable assets, stressing the significance of the quality of urban greenery in enhancing ecosystem services. Lastly, we highlight the importance of nurturing connections between urban residents and nature, fostering relational values crucial for sustained care and conservation of nature.

城市中的自然环境对人类的福祉至关重要。在热带地区，无法对大自然为城市居民提供的商品和服务进行量化和评估。然而，由于世界各地的城市都面临着类似的挑战，了解热带城市生态系统提供的服务对于有效管理变得至关重要。在这里，我们提出了热带城市的第一个自然资本评估，揭示了三个关键的见解。首先，我们展示了一个发达的热带城市对自然的重要依赖，特别是通过调节服务来减缓气候变化。其次，我们确定完整的自然区域是新加坡最宝贵的资产，强调城市绿化质量对增强生态系统服务的重要性。最后，我们强调培养城市居民与自然之间的联系的重要性，培养对持续照顾和保护自然至关重要的关系价值观。

The sustainable management of water, energy, and food is crucial for achieving regional development, especially in areas facing resource scarcity. However, the connections between ecosystem services (ESs) and human well-being (HWB) remain underexplored, particularly within the context of the water–energy–food nexus (WEF- nexus). This study investigates the spatiotemporal dynamics of ESs and HWB in the Jiziwan region of the Yellow River Basin from 2000 to 2020, using partial least squares structural equation modeling (PLS-SEM) to examine the interactions between these variables. Our results show that the four key ESs—water yield, sand fixation, carbon sequestration, and food supply—exhibit similar spatial patterns, with values decreasing from southeast to northwest, alongside an improving trend over time. HWB indicators overall increased, with the exception of good social relations, which declined. We found that the water and food systems positively impacted HWB, while the energy system showed a negative effect. These findings highlight the importance of integrating ESs into regional governance frameworks to enhance HWB, with implications for sustainable development in other regions facing similar resource challenges. The study provides a theoretical foundation for developing ESs management strategies from a WEF-Nexus perspective that can be applied to other water-scarce, resource-dependent regions worldwide.

水、能源和粮食的可持续管理对于实现区域发展至关重要，特别是在面临资源短缺的地区。然而，生态系统服务（ESs）与人类福祉（HWB）之间的联系仍未得到充分探索，特别是在水-能源-食物关系（WEF- nexus）的背景下。本文利用偏最小二乘结构方程模型（PLS-SEM）分析2000 - 2020年黄河鸡子湾地区生态环境质量和生态环境质量的时空变化特征。研究结果表明，4个关键的生态系统-水量、固沙、固碳和食物供应-呈现出相似的空间格局，从东南向西北递减，随着时间的推移呈提高趋势。除了良好的社会关系外，HWB指标总体呈上升趋势。研究发现，水系统和食物系统对HWB有正向影响，而能源系统对HWB有负向影响。这些发现强调了将可持续发展纳入区域治理框架以加强可持续发展的重要性，这对面临类似资源挑战的其他区域的可持续发展具有启示意义。该研究为从WEF-Nexus的角度制定可持续水资源管理战略提供了理论基础，该战略可应用于全球其他水资源短缺和资源依赖地区。

European forests are increasingly expected to provide a wide range of biodiversity and ecosystem services (BES) beyond timber production, positioning non-industrial private forest (NIPF) owners (hereafter, “forest owners”) as key contributors. An emerging question is how to engage forest owners in the needed forest management shift. To better understand the drivers of forest owner participation in voluntary agreements, we conducted a meta-regression analysis of 24 studies from survey-based, stated, or actual participation data, encompassing 28 distinct datasets and 571 observations from 12 European countries. The findings suggest that certain contract designs substantially enhance forest owner participation: short- and mid-term contracts of 1 to 30 years (as opposed to longer-term agreements), the inclusion of withdrawal clauses, non-restrictive management requirements, and higher compensation levels all promote uptake. Moreover, agreements centred on biodiversity, carbon, or forest multifunctionality attract higher participation than timber- or water-focused aims. Although trust between the actors is often considered important in the literature, we did not consistently detect such effects on participation rates. The results indicate a more consistent interest among forest owners in BES agreements after 2012, especially those centred on biodiversity and carbon aims as well as on multifunctionality, potentially reflecting broader policy trends and shifts in motivation among younger generations of forest owners, moving away from timber production. These insights offer practical lessons for policymakers and practitioners aiming to design effective, targeted incentives that leverage Europe’s privately owned forests to meet biodiversity and climate objectives.

越来越多的人期望欧洲森林在木材生产之外提供广泛的生物多样性和生态系统服务（BES），将非工业私人森林（NIPF）所有者（以下简称“森林所有者”）定位为关键贡献者。一个新出现的问题是如何使森林所有者参与必要的森林管理转变。为了更好地了解森林所有者参与自愿协议的驱动因素，我们对24项研究进行了荟萃回归分析，这些研究来自基于调查的、声明的或实际参与的数据，包括来自12个欧洲国家的28个不同的数据集和571个观察结果。调查结果表明，某些合同设计大大提高了森林所有者的参与：1至30年的短期和中期合同（相对于长期协议）、纳入退出条款、非限制性管理要求和更高的补偿水平都促进了森林所有者的参与。此外，以生物多样性、碳排放或森林多功能为中心的协议比以木材或水为中心的协议吸引更多的参与。虽然参与者之间的信任在文献中经常被认为是重要的，但我们并没有一致地发现这种对参与率的影响。结果表明，2012年之后，森林所有者对BES协议的兴趣更加一致，特别是那些以生物多样性和碳目标以及多功能为中心的协议，这可能反映了更广泛的政策趋势和年轻一代森林所有者的动机转变，他们不再从事木材生产。这些见解为旨在设计有效、有针对性的激励措施、利用欧洲私有森林实现生物多样性和气候目标的政策制定者和实践者提供了实践经验。

The role of arthropods as regulators of crop pests has gone underexamined in comparison to those species that are crop pollinators. While pollination services have been widely studied, the economic value of pest regulation provided by natural enemies remains underexplored. The suppression of insect crop pests by these natural enemies may provide substantial value to agriculture in reduced crop losses. Here, we estimate the economic value of pest regulation services provided by arthropod natural enemies in the UK for wheat (Triticum spp.), barley (Hordeum vulgare), and oilseed rape (Brassica napus) crops. We used a structured literature search to parameterise an economic production function to estimate the average annual value of pest regulation provided by arthropod natural enemies in the UK. We then simulated changes in economic benefits across different levels of natural enemy presence. A marginal 10% reduction from a full community of natural enemies had an estimated value per hectare between £108.98 − £171.13 for barley, £36.93 − £73.97 for oilseed rape, and £0.74 − £9.60 for wheat. We performed sensitivity analysis to evaluate how robust these benefits were across field management strategies. There are areas of uncertainty around the efficacy of natural enemies, crop yield response, economic thresholds, and field management. Resolving these sources of uncertainty and quantifying the economic value of pest regulation could inform sustainable pest management strategies and wider insect conservation practice.

节肢动物作为作物害虫调节者的作用与那些作为作物传粉者的物种相比，尚未得到充分的研究。虽然传粉服务已被广泛研究，但天敌提供的害虫控制的经济价值仍未得到充分探索。这些天敌对农作物害虫的抑制可以为农业减少作物损失提供重要价值。在这里，我们估计了节肢动物天敌在英国为小麦（Triticum spp.）、大麦（Hordeum vulgare）和油菜（Brassica napus）作物提供害虫治理服务的经济价值。我们使用结构化的文献检索来参数化经济生产函数，以估计英国节肢动物天敌提供的有害生物治理的平均年价值。然后，我们模拟了不同程度的天敌存在对经济效益的影响。在一个完整的天敌群落中，10%的边际损失对每公顷大麦的估计价值为108.98 - 171.13英镑，对油菜的估计价值为36.93 - 73.97英镑，对小麦的估计价值为0.74 - 9.60英镑。我们进行了敏感性分析，以评估这些效益在整个油田管理策略中的稳健性。在天敌的功效、作物产量反应、经济阈值和田间管理等方面存在不确定性。解决这些不确定性的来源和量化有害生物管制的经济价值可以为可持续的有害生物管理战略和更广泛的昆虫保护实践提供信息。

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。
