Mapping biodiversity and ecosystem service trade-offs and synergies of agricultural change trajectories in Europe

The intensification, extensification and abandonment of agricultural land will each play a major role in the future development of European landscapes. However, their impacts on various dimensions of sustainability vary spatially. This creates challenges but also opportunities for landscape managers and policymakers to optimize biodiversity and ecosystem services. In this study, we conduct a spatial assessment of the impacts of these three major agricultural development trajectories on ten ecosystem service and biodiversity indicators across the European Union (EU) and the UK. Using a spatial resolution of 1 km2, we exposed high spatial variation in impacts and strong differences in the spatial patterns depending on the indicator. Aggregating all positive and negative impacts of a trajectory, hot- and cold spots of total positive and negative impacts could be distinguished. An assessment of trade-offs and synergies between impacts of each trajectory was used to map areas dominated by beneficial impacts, detrimental impacts, or high trade-offs between impacts. The results indicate very diverse spatial trade-off and synergy patterns, with generally high sub-regional variation, emphasizing (i) the need for reflecting trade-offs and context-specificity in landscape planning and management and (ii) the potential advantages of spatial targeting of agricultural development and conservation strategies. Biodiversity and ecosystem service impact mapping exercises can, thus, be a major tool to effectively navigate trade-offs and synergies and explore effective sustainable landscape solutions.

Combining Ecological Niche Models and ecosystem services indicators to assess impacts of climate change on kelp: application to French coasts

ABSTRACT Kelp forests, primarily Laminaria digitata, provide a broad range of ecosystem services of high social, economic, and ecological value and are considered one of the most productive ecosystems on the planet. Several studies have shown that kelp ecosystems are regressing in response to multiple stressors, especially climate change, which could lead to local extinctions. This may induce a decrease in the ecosystem services provided. Many studies use ecological niche models (ENM) to project potential future species distributions under climate change scenarios; however, no study has projected the future supply of ecosystem services resulting from shifts in species ranges and changes in biomass. In this study, using French coasts as a case study, we developed a new and reproducible methodological framework that combines ENM and ecosystem services indicators to assess impacts of climate change on ecosystem services supplied by kelp. To this end, we first identified ecosystem services currently provided by kelp and then used ENM to project future kelp distribution from 2041 to 2050 under climate scenarios RCP2.6 and RCP8.5. Finally, by estimating the biomass of kelp, we assessed the current and future ecosystem services provided by kelp.

Provision of Ecosystem Services in Riparian Hemiboreal Forest Fixed-Width Buffers

The importance of riparian forest protection is widely acknowledged. However, scientific discussions are still ongoing as to the most suitable and effective protection activities for these forests. The quality of the provision of different ecosystem services in protected riparian forest buffers could provide an insight into the impact of protection regulations. Cultural ecosystem services in riparian forests have an important social-ecological context, especially with the growing interest in recreation activities in forests. The aim of our study was to compare provision of different ecosystem services in riparian forest buffers located both adjacent to (0–50 m) and distant from (51–200 m) the stream. In our study, four small-to-medium-sized rivers in Latvia were used. In total, six different indicators of ecosystem services were estimated, based on data from the National Forest Inventory and the European Soil Data Centre. Bayesian ordinal regression was employed to assess the differences between the two buffer strips. Our results showed that the majority of assessed ecosystem service indicators (Recreation potential of the forest ecosystem, Visual quality of the forest landscape, Potential for the presence of medicinal plants and Potential for the presence of nectar plants) were of higher quality in the adjacent (0–50 m) buffer. Only one indicator (Flora with phytoremediation potential) had significantly higher values in the distant buffer strips (estimate 0.24, CI: [0.11, 0.38]). The observed distribution of quality classes showed that, only for the indicator Potential of medicinal plants, the highest quality class was the most common (>60%), for other indicators dominated average quality class estimations. The obtained results suggested that the current protection status that riparian forest buffers have facilitated maintain the provision of several cultural and regulation & maintenance ecosystem services.

A methodology to evaluate the implementation of ecohydrology solutions at the Ecohydrology demonstration sites: The Guadiana case study

The Ecohydrology program of UNESCO established demonstration sites around the world where the ecohydrologic techniques are demonstrated to disseminate the concept and by learning from visualization of real in situ experiments and examples. To analyse the impact of applying ecohydrological solutions at the demonstration sites (eg. use of bivalves as filter feeders, phytoremediation or managing freshwater pulses), we propose to use ecosystem service indicators selected by expert judgment and literature. The ecosystem services (ES) concept provides a recognizable and easy way to evaluate the changes on the ecosystem, by measuring the improvement or degradation of the services that are provided. The proposed ES indicators table allows the evaluation of relevant ecosystem services, for all demosites by comparing the following three temporal situations: 1- before the impact occurred, 2 - after it occurred but without any restoration measure being implemented and; 3- after applying ecohydrology restoration solutions. The proposed Ecosystem services matrix was applied to the Guadiana estuary and adjacent coastal area demosite, in the south east of Portugal, based on extensive research on applying ecohydrology solutions at the site and expert judgement. Results show that the application of the Ecosystem Services (ES) matrix allows to understand the benefits of applying the ecohydrology approach, as it helps defining services and areas where more effort in recuperation is needed.

Modeling of flood regulation for ecosystem accounting: a case study of Ogosta river basin

The System of Environmental-Economic Accounting – Ecosystem Accounting (SEEA-EA) is a spatially-based, integrated statistical framework for organizing biophysical information about ecosystems, measuring ecosystem services (ES). Water flow regulation ES and biophysical modeling are among the main topics in the individual ES part of the SEEA-EA framework and flood regulation ES is one of the important services. Characterizing and assessing flood regulation is a challenging task as both assessment and accounts of this ES need various data which are usually not available through direct or indirect measurements, therefore modeling approaches of water regulation are much needed. Despite growing attention and studies using hydrologic models to assess and/or map flood regulation ES, the accounting of this service is still not well developed. In this paper, we present an approach for accounting flood regulation at a local scale using ArcSWAT modeling. It is based on the results of flood regulation ES assessment, where modeling results are used to quantify the ES indicators and delineate the service providing areas (SPA) and service demand areas (SDA). The actual flow of flood regulation is calculated as a ratio between ES demand and ES potential and it represents the area of SPA which corresponds to the demand for flood regulation represented by SDA. The results show that predominant flood regulations ES supply is provided by the forest ecosystem as well as the actual flow. The accounting of flood regulation is strongly determined by ecosystem extent mapping. The CORINE Land Cover (CLC) provides the most appropriate and available data for mapping ecosystem extent at smaller scales. However, at a larger scale, it is too coarse and the combination of Mapping and Assessment of Ecosystems and their Services (MAES) national ecosystem mapping gives better results.

How do anthropogenic pressures affect the provision of ecosystem services of small mountain lakes?

Although anthropogenic activities affect the ecological conditions of mountain lakes worldwide, the impacts on human wellbeing, in terms of ecosystem services provided by lake ecosystems, remain unclear. This study identified potential impacts of anthropogenic pressures on seven key ecosystem services of small mountain lakes. The Driver-Pressure-State-Impact-Response framework enabled conceptualization of hypothetical impacts of multiple indicators used to quantify ecosystem services. Results indicate that increasing temperatures influence almost all ecosystem service indicators, impacting negatively water availability in particular, but also exerting positive effects on recreation. Changes in water use have mostly negative impacts, specifically on indicators related to habitat and aesthetics. For indicators such as trophic state, water clarity, water availability, riparian vegetation complexity, and nitrate content, up to six pressures may interact. Overall, the greatest impacts can be expected on the ecosystem services habitat, water, aesthetic and existence. To support targeted management strategies, two contrasting groups of mountain lakes were distinguished, accounting for socio-ecological differences related to recreational and agricultural use. Lakes of low suitability for human use (i.e., high and/or remote) are mostly affected by large-scale drivers such as climate change, whereas lakes of high suitability for human use (i.e., low and/or easily accessible) are more often affected by pressures exerted by changes in local water use. These findings suggest that future research should emphasize interdisciplinary assessments in bridging limnological parameters to ecosystem service indicators, to better connect the pressures of global change to human benefits derived from mountain lakes. This information is useful for mitigating or adapting to the impacts of change.

The influence of discounting ecosystem services in robust multi-objective optimization – An application to a forestry-avocado land-use portfolio

Discounting is standard in economics to consider time preferences of people and account for future market changes. However, so far discounting has mainly been applied to monetary flows and ignored for many ecosystem services. In multi-objective optimization, selectively disregarding time preference for some non-monetary services create bias. Here we study how discounting a range of ecosystem service indicators influences a public planner's optimal land allocation. We used a robust multi-objective optimization approach to model a mixed forestry-avocado farm portfolio in South Africa. The objectives for optimization were the provisioning of various ecosystem services and disservices represented by four indicators: net present value, payback period, carbon sequestration, and fertilizer use. To account for time preferences concerning indicator flows, we applied specific discount rates to each ecosystem service indicator, depending on its character (non-monetary or monetary indicators). We demonstrate that discounting reduces the standard deviations of the discounted sum of the indicators, which leads to less diversified land-use portfolios. To account for discount rate uncertainty, we introduced three indicator sets simultaneously, each using a different discount rate, which was off setting the effect of decreasing diversification.

Smaller farm size and ruminant animals are associated with increased supply of non-provisioning ecosystem services

To balance trade-offs between livestock’s negative environmental impacts and their positive contributions (e.g. maintaining semi-natural grasslands, varied agricultural landscapes and crop rotations), a better understanding is needed of how the supply of ecosystem services differs across farms. We analysed a suite of indicators for non-provisioning ecosystem services on a large subset of Swedish farms (71% of farms, covering 82% of agricultural land) and related these to farm type, farm size and livestock density. The analysed indicators exhibited clear geographical patterns with hotspots especially in less productive regions. Controlling for this spatial variation we still found that small-scale and ruminant farms were associated with more varied landscapes, small-scale habitats, semi-natural grasslands and better crop sequences compared to nearby farms specialised in crop production, while farms specialising in monogastric livestock were associated with less varied landscapes and inferior crop sequences. Results for cultural ecosystem services indicated that farms with more semi-natural grassland were associated with more visitors and more likely located within designated recreation or nature conservation areas.

Ecosystem Service Assessment of Soil and Water Conservation Based on Scenario Analysis in a Hilly Red-Soil Catchment of Southern China

Soil and water conservation (SWC) practices on agricultural watersheds have been the most effective practices for preventing soil erosion for several decades. The ecosystem services (ES) protected or enhanced by SWC practices include the comprehensive effects of protecting and conserving water sources, protecting and improving soil, carbon fixation, increasing agricultural production, and so on. Due to the lack of ES evaluation indicators and unified calculation methods in line with regional characteristics, this study proposes a framework of scenario analysis by using ES mapping, ES scoring, and economic analysis technology for ES and economic-benefit trade-offs under different scenarios. The study area was the Xiaoyang catchment located in Ningdu County, Jiangxi Province, which is a typically hilly red-soil region of southern China. From the results of scenario analysis, an obvious phenomenon is that some SWC practices can affect the value of some ES indicators, while some have no clear trend. By computing the ES scores for the four scenarios, the ranking was S3 (balanced), S1 (conservation), S2 (economic), and S0 (baseline). S3 ranks second in net income (with CNY 4.73 million), preceded only by S2 (CNY 6.36 million). Based on the above rankings, S3 is the relatively optimal scenario in this study. The contributions of this study are the method innovation with the localization or customized selection of ES indicators, and scenario analysis with ES scores and economic-benefit trade-offs in different scenarios.

Participatory assessment to define indicators for monitoring water-based payment of ecosystem services programs in Brazil

The cascade model is a commonly applied framework to evaluate ecosystem services provision, highlighting their benefits to society and assigning non-monetary and monetary values to these services. Adapting this model, we present a methodology to establish the most suitable indicators for monitoring Payment for Ecosystem Services (PES) programs related to water resources in Brazil. Through a participatory process, a set of ecosystem functions indicators were assigned for each ecosystem service (ES) considered in the study. The indicators were then classified following these criteria: clarity, viability, sensitivity, and relevance. The indicators were organized by their final score according to each evaluated criterion. The results demonstrated that “clarity” and “relevance” criteria were those most important for the experts to choose an indicator. In general, we could also observe a preference for analytical and well-established indicators in the literature for all ES evaluated. The indicators list presented can support the PES program monitoring in Brazil. Additionally, the methodology developed can be easily applied in other areas and provide the definition of the most suitable indicators to monitor water-based PES in different Brazilian contexts.

An Ecosystem Service Approach to Assessing Agro-Ecosystems in Urban Landscapes

Creating sustainable urban landscapes in light of growing population pressures requires interdisciplinary multi-functional solutions. Alternative agro-ecosystems described as food forests, permaculture gardens, and/or edible landscapes among others could offer potential ways to address the social, economic, and ecological goals of various stakeholders simultaneously. Current research is lacking a comprehensive tool that can assess the performance of alternative agro-ecosystems that have both functional and aesthetic values. The present research uses a novel rubric, the Permaculture and Agro-ecosystems Sustainability Scorecard (PASS) that combines agricultural sustainability and ecosystem services (ES) indicators in order to assess alternative agro-ecosystems. The rubric evaluates provisioning, regulating, supporting, economic and cultural ES and includes benefits such as pollinator presence, increased biodiversity, alternative pesticides and fertilizer use, carbon sequestration, food security, and human interactions. Based on the concepts and principles drawn from four popular frameworks and sub-disciplines, namely, SAFE, SITES, permaculture, and agroecology, we identify sixteen broad ES indicators and 59 sub-indices and measure them using data collected through site observation, survey, interviews, and documentary research. For easy comparison across different urban agriculture sites, the above sub-indices are further aggregated into five ES criteria using stakeholder-informed weights. The weights are developed through pair-wise comparison of criteria by sample survey respondents. The PASS framework is used to score twelve sites in South Florida that meet specific criteria in the small farm, residential, and public space categories. Sample respondents place the highest weight on cultural services. Contrary to the popular notion of promoting urban agriculture for food security, the results show that the majority of the sites score highest in the supporting services provided, followed by regulating and cultural services, and lowest in the economic services category. The supporting service for most of the sample sites score consistently very high, close to the highest possible level of 5.0. There is a wide variation in provisioning and economic values across the study sites. The paper offers several ideas for mainstreaming the ES indicators into urban planning and decision-making and some of the practical difficulties one might face along the way. We conclude that in order to realize the broader ES benefits of urban agriculture in particular and agro-ecosystems in general, a multi-pronged policy and planning approach is necessary.

Towards ecosystem service assessment: Developing biophysical indicators for forest ecosystem services

Forests are specifically relevant for biodiversity and provide a wide range of ecosystem services. However, Europe’s forests and their services are threatened. Temperate, boreal and Mediterranean forests are facing deforestation, fragmentation and conversion due to human impact and recent developments in climatic conditions.Currently, not all forest ecosystem services are comprehensively accounted for and often, primarily timber production is considered. The aim of the present article is to further develop forest ecosystem service assessment using a systematic approach to assess biophysical indicators for ecosystem services. In this way, we aim to promote the use of forest function mapping, which is an important planning tool in the Central European forest sector for mapping forest areas of particular relevance for protection and recreation. Building on forest function mapping and the Common International Classification of Ecosystem Services (CICES 5.1), we selected six ecosystem services and propose indicators for their biophysical quantification. The indicator selection process followed specific selection criteria.We propose indicators for the potential, supply, demand and flow of the following forest ecosystem services: (i) groundwater for drinking purposes, (ii) timber provision, and (iii) global climate regulation. For the ecosystem service (iv) local air pollution reduction, indicators for potential, demand and flow are proposed, for (v) recreation, as well as (vi) education and training, indicators for the ecosystem services’ supply, demand and flow are proposed. In addition, possible measuring methods and units, and necessary data sources for applying the indicators are provided.

Effective restoration measures in river‐floodplain ecosystems: Lessons learned from the ‘Wilde Mulde’ project

AbstractOver the last 40 years, a growing number of restoration projects have been implemented to improve the ecological conditions of highly degraded rivers and their floodplains. Despite considerable investment in these projects, information is still limited about the effectiveness and the success of such river restoration measures, mainly due to a lack of standardised and interdisciplinary assessment approaches. During the project ‘Wilde Mulde—Restoration of a dynamic riverine landscape in Central Germany’, we implemented hydromorphological restoration measures (installation of large wood, removal of rip‐rap, reconnection of a former river side‐arm) along a lowland river in Central Germany. We carried out intensive scientific monitoring of biodiversity, hydromorphology, ecosystem functions and services, as well as socio‐economic aspects. A Before/After‐Control/Impact (BACI) design was used to identify the spatial and temporal effects of the restoration measures and to distinguish them from changes caused by background variation. For this, we used a comprehensive set of indicators, including abiotic (flow velocity, diversity of riverbed topography, and flow resistance), biological (ecosystem respiration, macroinvertebrates, fish, carabids, vegetation, and birds) and socio‐economic (acceptance and public awareness) indicators as well as the ecosystem service indicator aesthetic quality of the landscape. To meet the inherent challenges of such a large‐scale field experiment, like unpredictable environmental conditions, we used an experimental approach that allowed us to demonstrate a measurable success of the implemented restoration measures. The majority of the abiotic and some of the biological and socio‐economic indicators at the restored sites approached values of a natural reference site while already deviating from values of a nonnatural reference site two years after restoration. In addition to the applied interdisciplinary approach, multiple scales of field investigations and data analyses are essential as key components for evaluating successful river and floodplain restoration projects.

Indikatoren und Methoden zur Erfassung und Bewertung von Ökosystemleistungen in metropolitanen Räumen

This paper presents a scientifically credible and practically relevant set of indicators and methods to assess and evaluate ecosystem services of relevance for land use and landscape planning. The research questions are (i) to identify suitable ecosystem services, indicators, and methods, and (ii) to assess the proposed indicators regarding the respective data availability and assessment effort. The region of Frankfurt/Rhein-Main (Germany) serves as the case study. The methods include the synthesis of a specifically adapted list of ecosystem services indicators based on relevant prior research and an expert-based and application-oriented evaluation. The proposed list for the region of Frankfurt/Rhein-Main contains 27 ecosystemservices, with one or more associated indicators each. The evaluation reveals that metropolitan regions in Germany usually provide sufficient data to assess almost all ecosystem services. The assessment effort differs, but is generally moderate. The paper concludes with recommendations for practical application in the Frankfurt region and beyond.

Permanent grasslands in Europe: Land use change and intensification decrease their multifunctionality

Permanent grasslands cover 34% of the European Union’s agricultural area and are vital for a wide variety of ecosystem services essential for our society. Over recent decades, the permanent grassland area has declined and land use change continues to threaten its extent. Simultaneously, the management intensity of permanent grasslands increased. We performed a systematic literature review on the multifunctionality of permanent grasslands in Europe, examining the effects of land use and management on 19 grassland ecosystem service indicators. Based on the evidence in 696 out of 70,456 screened papers, published since 1980, we found that both land use change and intensification of management decreased multifunctionality. In particular, preventing conversion of permanent grasslands to croplands secured the delivery of multiple ecosystem services. A lower management intensity was associated with benefits for biodiversity, climate regulation and water purification, but impacted the provision of high-quality animal feed. Increasing the number of species in the sward enhanced multifunctionality of permanent grassland without significant trade-offs such as losses in production. Our review covered many aspects of land use, management and ecosystem services, but we also identified areas with no or only few studies. The most prominent gaps were related to comparisons between permanent and temporary grasslands, and effects of management practices on the provision of cultural values, and on erosion and flood control. We suggest that, despite apparent changes in human dietary preferences, the protection of permanent grasslands in Europe must be prioritised. At the same time, considering the need to reduce ruminant livestock’s contribution to climate change, the time seems ripe to increase support for low-intensity grassland management to optimise the provision of essential ecosystem services from Europe’s permanent grasslands.

Plant functional traits as measures of ecosystem service provision

AbstractDespite the relevance of ecosystem services (ES) to society and modern ecological research, current methods of measurement and mapping remain inconsistent and often lack primary data in estimating and modeling ES. A key player in our understanding of ES and their measurements are plant functional traits—chemical and physical aspects of plants—which are often cited as one of the drivers of ecosystem processes and functions. In order to better quantify the ES–plant functional trait indicators, we outline existing evidence of this relationship and identify gaps between the best predicted ES and the most valued ES. This study offers an up‐to‐date review of plant functional traits' direct or indirect relationships with ecosystem service provision and discusses the quantitative evidence these traits might hold as indicators. With this review, we seek to (1) offer a current summary of the quantitative evidence on ecosystem service–plant functional trait relationships, (2) identify which traits have been used to successfully indicate ecosystem services, and (3) identify research gaps, and ecosystem services or traits that receive little attention or have weak criteria as indicators. In a comprehensive literature review of the 19 services that were searched for, genetic materials, medicine, and cultural services had no relevant plant functional trait indicators, while the remaining 16 services had a range of traits associated with them. We found that functional traits showed varying relationships to ES, with some depending on the ecosystem type they were found in, while others appeared to remain consistent across ecosystems and conditions. This indicates that there could exist a subset of traits that are “universal” indicators across all ecosystem types, while others are ecosystem dependent. Our review suggests the need for more research on less clearly defined ES (such as cultural, educational, and refugium services) both by more careful definitions to make quantitative measures more applicable, and through increased quantitative and qualitative studies to better understand the nature of ES indicators for these services. This summary shows how plant functional traits can quantitatively and reliably predict and provide details on a subset of ES.

Spatiotemporal valuation of cultural and natural landscapes contributing to Pakistan's cultural ecosystem services.

Cultural ecosystem services are the non-material benefits that people obtain from ecosystems and these services are subject to tremendous anthropogenic and climatic pressures. This study evaluates the spatiotemporal economic valuation of selected cultural and natural landscapes in Pakistan using net present value method. The results indicate that both cultural landscapes and mountain ecosystems are the most significant contributors to Pakistan's cultural ecosystem services. The net present value of our study area was USD 96/ha, while this value is ranged from USD 0.000242/ha to USD 138,997/ha in the 42 previous studies selected for comparison. Service flow, population, and visitor numbers were the most significant indicators of cultural ecosystem services. The promotion of cultural ecosystem services as an inclusive service and the application of discounted rates are identified as key approaches for ensuring sustainable resource use and enhanced intergenerational benefits by incorporating cultural ecosystem services into the national policy framework.

Spatial scaling of land use/land cover and ecosystem services across urban hierarchical levels: patterns and relationships

Land use/land cover (LULC) patterns seriously affect ecosystem services (ESs), especially in highly developed urban agglomerations. Exploring how LULC and ESs change spatially across urban hierarchical levels and understanding the possible mechanisms can promote the sustainable planning of urban landscapes. By mapping the spatial patterns of LULC and ESs in the three largest urban agglomerations of China, this study aimed to (1) identify the scaling relations of LULC and ESs across different urban hierarchical levels, (2) explore the possible mechanisms of these two types of spatial scaling, and (3) examine how the scaling relations of ESs relate to LULC and the policy implications. Based on LULC, we used the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model and other biophysical models to quantify ES indicators. Then, scalograms were used to quantify the scaling relations of LULC and ESs with respect to changing spatial extent. Developed land and cropland exhibited the most predictable responses with changing spatial extent. Compared to other ESs, provisioning services were the most predictable. The predictable scaling relations of ESs at different urban hierarchical levels fell into two general types: power laws at the city proper level and exponential relationships at the metropolitan region and urban agglomeration levels. The scaling relations of both LULC and ESs varied across urban hierarchical levels. The spatial scaling of ESs was closely related to LULC patterns. Integrating the scaling relations of ESs into land use planning can help decision-makers formulate multi-scale landscape conservation strategies.

CPSDv0: a forest stand structure database for plantation forests in China

ABSTRACT Forest stand structure is not only a crucial factor for regulating forest functioning but also an important indicator for sustainable forest management and ecosystem services. Although there exists a few national/global structure databases for natural forests, a country-wide synthetic structure database for plantation forests over China, the world’s largest player in plantation forests, has not been achieved. In this study, we built a country-wide synthetic stand structure database by surveying more than 600 peer-reviewed literature. The database covers tree species, mean stand age, mean tree height, stand density, canopy coverage, diameter at breast height, as well as the associated ancillary in-situ topographical and soil properties. A total of 594 published studies concerning diverse forest stand structure parameters were compiled for 46 tree species. This first synthesis for stand structure of plantation forests over China supports studies on the evolution/health of plantation forests in response to rapid climate change and intensified disturbances, and benefits country-wide sustainable forest management, future afforestation or reforestation planning. Potential users include those studying forest community dynamics, regional tree growth, ecosystem stability, and health, as well as those working with conservation and sustainable management.

Assessment of ecosystem services for urban regions in the context of the Sustainable Development Goals exemplified by the Bonn/Rhein-Sieg region

Abstract The implementation of the Sustainable Development Goals (SDGs) and the conservation and protection of nature are among the greatest challenges facing urban regions. There are few approaches so far that link the SDGs to natural diversity and related ecosystem services at the local level and track them in terms of increasing sustainable development at the local level. We want to close this gap by developing a set of indicators that capture ecosystem services in the sense of the SDGs and which are based on data that are freely available throughout Germany and Europe. Based on 10 SDGs and 35 SDG indicators, we are developing an ecosystem service and biodiversity-related indicator set for the evaluation of sustainable development in urban areas. We further show that it is possible to close many of the data gaps between SDGs and locally collected data mentioned in the literature and to translate the universal SDGs to the local level. Our example develops this set of indicators for the Bonn/Rhein-Sieg metropolitan area in North Rhine-Westphalia, Germany, which comprises both rural and densely populated settlements. This set of indicators can also help improve communication and plan sustainable development by increasing transparency in local sustainability, implementing a visible sustainability monitoring system, and strengthening the collaboration between local stakeholders.
