Optimizing afforestation and reforestation strategies to enhance ecosystem services in critically degraded regions

Human activity has caused massive forest ecosystem damage, threatening the global environmental balance. Afforestation and reforestation are crucial strategies for the restoration of forest ecosystem functions. This study was conducted on Belitung Island, Indonesia, which has experienced forest degradation due to mining activity and is currently undergoing forest restoration efforts. This study aimed to identify priority areas for afforestation and reforestation using an innovative approach that integrates multi-criteria analysis (MCA) and machine-learning techniques based on ecosystem service (ES) indicators, wildfire susceptibility, and environmental pressure. This study is the first to combine long-term remote sensing data with machine learning to develop priority scenarios for afforestation and reforestation. Results show that low-priority afforestation areas cover 24,479.66 ha (20.45 %), medium-priority areas 58,703.30 ha (49.04 %), and high-priority areas 36,521.98 ha (30.51 %). For reforestation, low-priority areas cover 23,123.45 ha (30.45 %), medium-priority areas 38,197.36 ha (50.3 %), and high-priority areas 14,618.27 ha (19.25 %). This study is expected to serve as a reference for sustainable forest ecosystem restoration efforts in various regions by leveraging ES approaches and environmental conditions using remote-sensing technology.

The Integrated Analysis of Territorial Transformations in Inland Areas of Italy: The Link between Natural, Social, and Economic Capitals Using the Ecosystem Service Approach

This paper examines how spatial dynamics have impacted natural capital and the provision of ecosystem services. The units outlined by the National Strategy for Inland Areas (SNAI) have been used as the territorial units for this study. The SNAI is a public policy focused on enhancing the quality of services to citizens (such as transportation, healthcare, and education). It proposes the economic revitalization of inland areas undergoing processes of marginalization. Our focus on inland areas stems from two primary reasons: first, no previous studies in Italy have analyzed the changes in ecosystem services in SNAI areas; and second, SNAI areas are well-suited to providing ecosystem services that are in demand by urban areas. Although this study does not cover all aspects inherent to the topic, it represents a starting point aimed at understanding the links between environmental and socio-economic dynamics and ecosystem service changes. This is essential for both current and future generations. By analyzing the processes of permanence and transformation, modifications in the supply–demand balance have hereby been studied, as well as the economic variations in ecosystem services. The period considered runs from 1990 to 2018. These findings could help governmental institutions in developing sustainable governance models, in line with spatial policies and strategies.

Ecosystem Services Justice: The Emergence of a Critical Research Field

Ecosystem services justice is an emergent research field. Over the past decade, research on ecosystem services has increasingly developed a justice perspective and incorporated it into its conceptual and empirical frameworks. This perspective aims at providing a review of the emergent strands of research addressing ecosystem services justice, and at creating an outlook on future research needs and frontiers. The review departs from central critiques to the ecosystem service approach, which have been foundational for the research field of ecosystem services justice. To be precise, we address three different research strands on which justice issues arise. First, ecosystem services production, considering the (increasing) commodification of ecosystem services, the concentration of ecosystem services production assets and the role of trade-offs in production capacities. Second, the distribution of ecosystem services benefits under the aspects of unequal vulnerabilities, the consideration of accessibility and individual’s capabilities to obtain ecosystem services. Third, the recognition of ecosystem services pluralisms, including socially differentiated forms of wellbeing, plural values and knowledge concerning ecosystem services. While ES justice has strongly advanced from a scientific perspective, we are still lacking a stronger reflection of these advances in practice. Future research, we argue, needs to develop holistic procedural frameworks for integrating the complexity of ecosystem services justice, addressing the ecosystem services production under consideration of historic inequalities, the distribution of ecosystem services benefits with respect to people’s diverse needs, vulnerabilities, and capabilities, as well as diverse wellbeing-, value-, and knowledge-systems. The social-ecological understanding of ecosystem services co-production, which recognizes the dynamic and reciprocal relationship between humans and ecosystems, is identified as a crucial framing for this endeavor.

Environmental and legal aspects of the armed aggression of the Russian Federation against Ukraine

The article examines the environmental and legal aspects of the armed aggression of the Russian Federation against Ukraine. The problems of bringing the aggressor state to responsibility for ecocide are analyzed. Having found a legislative enshrinement in the national criminal law (Article 441 of the Criminal Code of Ukraine), ecocide has not been enshrined in international criminal law. It is not recognized as a crime either in the Rome Statute of the International Criminal Court or in any other international legal act. As of today, Russian crimes against the environment can be investigated by the International Criminal Court as war crimes. The author of the article supports the proposal regarding the need to include the crime of ecocide in the Rome Statute. The ecological and legal aspect of the formation of an international compensation mechanism is studied, the components of which are: 1) an international register of damages; 2) compensation commission (which will consider individual applications for compensation by the Russian Federation for losses from citizens, companies and the state); 3) compensation fund (which will accumulate funds to pay commission decisions, including at the expense of confiscated Russian assets). The mechanism of compensation for environmental damage caused as a result of the armed aggression of the Russian Federation against Ukraine is analyzed, and ways of its optimization are proposed. The future compensation mechanism should be based on the «ecosystem services approach», which will significantly increase the amount of environmental damage that the Russian Federation will pay to Ukraine. The international practice of compensation for environmental damage caused by the aggressor as a result of military actions and temporary occupation was studied and analyzed. The author emphasized the need to reform the state environmental monitoring system. Without reliable monitoring data, it is difficult to prove a causal relationship between the illegal actions of the aggressor state and the damage caused to the environment.

Examining the Mediating Effect of the Rural Economic Dynamization between the Socio-Environmental Heritage and Sustainability of Protected Areas

This study examines the mediating effect of rural economic dynamization between socio-environmental heritage and the sustainability of protected areas in the buffer zone of the Serranía de las Quinchas Regional Natural Park, located in the municipality of Otanche, Boyacá Department, Colombia. The study population includes families that are part of the productive units in this area. The methodological approach of this study is based on partial least squares structural equation modeling. The working unit was established in the regional protected areas of Colombia, specifically in the Serranía de las Quinchas Regional Natural Park. A sample of 172 participants was selected using a non-probabilistic intentional sampling method, covering academics, company representatives, social leaders, local authorities, and representatives of non-governmental organizations. The study variables were measured using a scale with satisfactory psychometric properties, which included 12 items for socio-environmental heritage, 17 items for rural economic dynamization, and 11 items for the sustainability of protected areas. These were structured into subcategories based on the ecosystem services approach (factors that demonstrate social and economic dynamics). Responses were collected using a five-point Likert scale. The sample was analyzed using SmartPLS 3.3.3 software, applying a reflective–reflective hierarchical component model to evaluate the first- and second-order relationships among the variables. The results demonstrate the importance of socio-environmental heritage for local communities as a strategic component that facilitates the rural economic dynamization of protected areas based on sustainability. This research contributes to understanding the relationship between socio-environmental heritage and the sustainability of protected areas, mediated by rural economic dynamization, highlighting the relevance of in situ conservation strategies and prospective planning of these territories to implement sustainability dynamics. It is concluded that rural economic dynamization acts as a significant mediator in the relationship between socio-environmental heritage and the sustainability of protected areas, emphasizing the need to integrate these dynamics into the management of natural resources and the promotion of sustainable development in rural communities.

Ecosystem Services Approach in Turnicki National Park Planning: Factors Influencing the Inhabitants’ Perspectives on Local Natural Resources and Protected Areas

Despite changing paradigms in nature conservation, protected areas, such as national parks, remain key tools for nature conservation. Today, protected areas are perceived as socio-ecological systems, therefore using an ecosystem services approach may help in their designation. Here, we focus on the planned Turnicki National Park located in the far eastern part of the Polish Carpathian Mountains and conflict between proponents of the park establishment and local stakeholders. We used an ecosystem services-driven questionnaire survey among local communities to analyze interactions between the perception of ecosystem services and opinions about national parks, and the role of social and economic status in shaping these opinions. We found links between opinions towards national parks and other factors: age, life span in a municipality, level of education, and an average net income. Respondents who perceived benefits from nature were more positive towards national parks in general and the Turnicki National Park specifically; however, those who prioritized provisioning services were more skeptical. Also, we distinguished four Fuzzy-Set Qualitative Comparative Analysis models which describe factors shaping opinions on national parks, respectively. The study has shown that the ecosystem services lens perspective can help in exploring the factors crucial while establishing the protected areas in specific social and economic context. The main implication for the study is careful consideration of the role of national park to protect the local environment in harmony with social needs and economic development.

Review of forest ecosystem services evaluation studies in East Africa

The East African region hosts diverse forest ecosystems, such as woodlands, highland forests, and coastal mangrove forests. These ecosystems are crucial for biodiversity and support various plant and animal species. They provide essential resources, benefiting livelihoods directly and indirectly. Examining regional and global variations in forest ecosystem valuation, especially regarding livelihood benefits, is crucial for sustainable resource management aligned with forest-based climate solutions. The aim of this review is to assess how regional contextual factors and global trends impact the valuation of ecosystem services (ES) in East Africa, with two main objectives (1) to identify the most evaluated ES in East Africa and (2) to identify the preferred ES valuation methods and approaches applied in East Africa. Data from the Web of Science/Clarivate platform was used in the systematic review process using the Reporting standard for Systematic Evidence Syntheses to retrieve and analyse 222 articles. The ES were categorized using the Millennium Ecosystem Assessment framework and the Common International Classification of Ecosystem Services in order to create a review database. Provisioning services i.e., wood biomass and food production were the most assessed at 55%, followed by 30% regulating services i.e., carbon storage, 8.6% support services i.e., habitat and 6.4% cultural services i.e., ecotourism which reflected communities’ direct reliance on forest resources. The preferred direct ES valuation techniques included market price at 14.9% for assessing provisioning services and travel cost methods at 10.4% for cultural services. Amongst the indirect ES valuation techniques, remote sensing at 14.7% were preferred as they proved efficient for large and remote tropical forest areas. Participatory methods such as interviews at 11.8% were also preferred because they offer holistic perspectives on community priorities. This review provides spatial context on the regional priorities of ES valuation which is vital for safeguarding natural resources for future generations.

Disentangling soil-based ecosystem services synergies, trade-offs, multifunctionality, and bundles: A case study at regional scale (NE Italy) to support environmental planning

The explicit use of ecosystem services (ESs) assessments has been called as a way to guide environmental decision making, yet the promise of the ES approach lies behind its potential. A way to consolidate the approach could be to introduce some aspects into the ESs assessments which might have been neglected so far. Such aspects are mainly: (1) a focus on the complex ESs relations (such as synergies and trade-offs) that can impact the supply of multiple SESs (soil ecosystem services), and (2) focus on potential drivers of SESs relations. We applied bivariate and multivariate approaches to SESs indicators derived from a solid pedological knowledge of the Emilia-Romagna study area in NE Italy. We focused on 7 SES: (1) habitat for soil organisms, (2) filtering and buffering capacity, (3) contribution to microclimate regulation, (4) carbon sequestration, (5) food provision potential, (6) water regulation, and (7) water storage capacity. These SESs were estimated through a combination of point observations, and pedotransfer functions (PTF) estimates spatialised over the area of interest with geostatistical simulation techniques. We found that SESs bivariate spatial relations could be categorised mainly in three types of patterns at regional scale, either: (1) synergistic SESs relations dominating at the region level, (2) trade-offs dominating, or (3) both kind of relations more or less equally frequent. Interestingly, in some cases the dominant regional SESs relation switched at a local level, and such switch was driven by soil properties. For the multivariate case (>2 SESs), two main results are highlighted. First, the combination of properties of some soils is so characteristic that they conform a single SESs bundle, as in the case of the rich SOM soils of alluvial origin in the NE of the region with low agricultural productivity, but high value in regulating SESs. Secondly, some SESs such as potential food provision and water regulation are more important than others to determine locations with high multi-services value at a regional level. This suggests that attention must be paid when ascribing high multi-services value locations as this is not independent of SESs relations. Overall, our results highlight the importance of soils in the potential supply of ESs and show that SESs relations are useful in the implementation of the concept in environmental assessments.

Assessment of vegetation restoration impacts on soil erosion control services based on a biogeochemical model and RUSLE

Study regionLoess Plateau, China Study focusThe potential soil erosion has commonly been estimated using the revised universal soil loss equation (RUSLE) under bare land conditions. In few studies, biogeochemical models have been employed to simulate natural vegetation dynamics and assess the effects of regional vegetation restoration on soil loss control. In this study, a biogeochemical Biome-BGC (BBGC) model was developed to simulate the potential vegetation dynamics. The soil erosion rate and erosion control indices under both the current land use/cover (A, ERI) and the potential vegetation conditions (A’, ERI’) were estimated using the RUSLE model and an index-based ecosystem service approach, respectively. The effects of vegetation restoration on erosion control services were ultimately evaluated. New hydrologic insights for the regionThe BBGC model performed well in simulating the potential vegetation dynamics. The average annual soil retention increased by 84% after vegetation restoration since 1999. The increased erosion control services accounted for 62% of the Loess Plateau. Erosion control services increased to a high degree (ERI-ERI’ >0.4) in the southeast. Our results demonstrated that vegetation restoration effectively improved the erosion control services on the Loess Plateau. The results could provide a guidance in quantifying the regional effects of vegetation restoration on ecohydrological services and protecting the soil conservation function of watershed ecosystems.

Economic trade-offs of harvesting the ocean twilight zone: An ecosystem services approach

The mesopelagic or ocean twilight zone (OTZ) in the ocean contains huge numbers of fish in a relatively pristine environment and may therefore attract interest as a commercial fishery. In this study we evaluate in economic terms, the likely trade-offs between the different services provided by the mesopelagic layer in the Bay of Biscay and the societal benefits of its commercial exploitation. Benefits arise mainly from the likely use of this group of species as raw material for producing fishmeal and fish oil. Costs are derived from the loss in climate regulating and cultural, services, but also from the loss in the provisioning service of other commercial species. To do so we compare the current non-exploited status with a situation in where mesopelagic fishes are harvested at levels capable of producing the Maximum Sustainable Yield. Results suggest that if mesopelagic fishes are harvested, a mean value of 1.2 million Euro loss in a year will be created in the Bay of Biscay, although in a range between 42 million Euro loss and 48 Euro million benefits. This uncertainty comes, mainly, from the limited existing knowledge of the mesopelagic fishes’ biomass but also from the uncertainty on the biomass of the rest of the species of the studied ecosystem. The large range indicates that a better understanding of the mesopelagic ecosystem is needed, however, results also show that ecosystem services under no exploitation provided by the OTZ could be more valuable than the fishmeal and fish oil that potentially could be obtained from the fishes harvested in this sea layer.

An early career researchers’ perspective on inequality in ecosystem services research in Asia

The ecosystem services (ES) approach has been widely applied for assessing nature’s values and human-nature links. Over the past two decades, this research approach has experienced remarkable growth, exerting global influence on the sustainability policy agenda. Recent literature indicates that North America, Europe, East Asia, and Australia are major contributors to ES research, while other regions are progressing at a slower pace. Many countries in these regions remain under-represented due to various factors, including but not limited to knowledge transfer gaps, disparities in research capacities, as well as distinct needs and challenges among researchers in the Global North and South. Although the ES literature in Asia is growing in topics, methodologies, quality and quantity, many Asian researchers, especially Early Career Researchers (ECRs), still face problems typical of the Global South while conducting ES research. In this paper, we outline four major challenges from the perspective of ECRs. They include: 1) Inequality in career prospects and capacity-building, 2) Inequality and challenges in data access & knowledge transfer, 3) Circulation of research findings in global scientific publishing, 4) Challenges in funding. This perspective paper draws special attention to the challenges faced by ECRs in ES research in Asia. By presenting recommendations, we strongly advocate that the research community work together to make ES research a level playing field for ECRs like ourselves working in Asia and elsewhere.

Assessment of Coastal Cultural Ecosystem Services and Well-Being for Integrating Stakeholder Values into Coastal Planning

Coastal areas provide ecosystem services (ES), including a wide range of cultural ecosystem services (CES). This study aims to operationalize the ES approach for integrated assessment and mapping of coastal CES through the case of the eastern Baltic Sea coast in Latvia. It explores an interdisciplinary approach to enhance coastal planning, leveraging the strengths of plural disciplines to ensure a more holistic representation of coastal CES. A set of methods and techniques from landscape ecology (e.g., landscape characterization, quality assessment, biophysical mapping) and social sciences (participatory GIS, stakeholder engagement events, nationwide survey) are developed and tested, particularly demonstrating links and correlations between landscape character and CES values and well-being dimensions. The results illuminate the main perceived well-being benefits that people gain from the coastal areas, highlighting the different perspectives of stakeholders. Finally, the integrated assessment results helped to construct proposals for sustainable tourism development in the area. The outcomes of the study are intended to assist planners and decision-makers in evaluating the potential for development and trade-offs in coastal regions. This research contributes to the advancement of coastal spatial planning methodologies, emphasizing the importance of stakeholder engagement and ES assessment for informed decision-making.

Identification of River Ecosystem Services through Water Utilization at Merapi Volcano, Indonesia

Merapi volcano is renowned as one of the world’s most active and densely populated volcanoes. Despite the constant high risk it presents, local residents continue to inhabit the Merapi slopes, primarily due to the ecosystem services that sustain their lives. River ecosystem services in this area are particularly vulnerable to landscape changes, largely driven by volcanic eruptions and human activities. This study aims to define the river ecosystem services by exploring the water utilization in Krasak River, which has been affected by Merapi eruptions from 2010 to 2023. The evaluation of water utilization was conducted using an ecosystem services approach, involving semi-structured interviews with 42 informants in six villages located along the upstream, middle stream, and downstream of the Krasak River. Content analysis was employed to explore water utilization practices and categorize river ecosystem services. The results revealed that water utilization in Krasak watershed comprises the use of springs and wells for supplying drinking needs and domestic needs as well as the use of rivers for irrigation water, fish ponds and recreation activities. Variations in Krasak River water utilization in different segments were influenced by water quality, quantity, accessibility, and the availability of alternative water sources. Based on local perspectives, the prominent river services encompass provisioning (e.g., irrigation, fish ponds, rural water supply, sand and stones), regulating (e.g., water quality maintenance, groundwater quantity), supporting (e.g., primary productivity), and cultural (e.g., recreation, aesthetic value) services. Challenges to river ecosystem services include concerns about river water utilization’s impact on perceptions of the river’s value and the roles of local communities and government in Krasak River management. These findings would contribute valuable insights for enhancing sustainable water resource management in the Merapi area.

The free energy of an ecosystem: towards a measure of its inner value

Based on a free energy approach, we propose the estimation of an ecosystem’s Inner Value, which is both non-instrumental and objective, reflecting the ecosystem’s value for itself as a natural entity, abstracted from any human valuation. The ecosystem services approach has become the dominant criterion for studying human and natural relationships, but this and similar approaches concentrate on the human advantage giving little or no regard for the well-being of the ecosystem. Although there is concern about preserving and recuperating damaged ecosystems, we seldom consider how much the ecosystem values itself. Then, we propose that Inner Value could be a tool to evaluate and model ecosystems’ health before any anthropic disturbance, allowing comparison with the impact these disturbances may have in the future. We also suggest that it should be a requirement for any Environmental Impact Assessment.

Climate Proofing Cities by Navigating Nature-Based Solutions in a Multi-Scale, Social–Ecological Urban Planning Context: A Case Study of Flood Protection in the City of Gothenburg, Sweden

Due to unsustainable land management and climate change, floods have become more frequent and severe over the past few decades and the problem is exacerbated in urban environments. In the context of climate-proofing cities, the importance of nature-based solutions (NBSs), obtaining relevant outcomes in the form of ecosystem services, has been highlighted. Although the role of ecosystem services in building resilience against negative climate change effects is widely recognized and there is an identified need to better integrate ecosystem services into urban planning and design, this has proven difficult to operationalize. A critical limitation is that modeling is a time-consuming and costly exercise. The purpose is to roughly estimate the ecosystem service of water run-off mitigation through simplified, cost-effective, and user-friendly modelling at three nested biophysical scales, under four climate change scenarios. Using the Swedish city of Gothenburg as an example, we propose an approach for navigating NBS-oriented flooding adaptation strategies, by quantifying the ecosystem service of water run-off mitigation at three nested biophysical scales, under four climate change scenarios, hence, proposing an approach for how to navigate nature-based solutions in a multi-scale, social–ecological urban planning context against present and future flooding events. Our findings validate the effectiveness of employing an ecosystem service approach to better comprehend the significant climate change issue of flooding through user-friendly and cost-efficient modeling.

Material flows as Earth politics: Concepts, methods, and approaches for transdisciplinary diagnostics and repair at Muizenberg East, Cape Town

Muizenberg East, in Cape Town, South Africa, is a peri-urban landscape that encompasses sewage works, tourist beaches, a nature reserve, a waste dump, a Ramsar site for the protection of migrating birds, shack settlements, and a corporate office park. The complex and contradictory uses of this land demonstrate the limitations of social-ecological analysis and ecosystem service approaches to environmental governance. Mapping contemporary struggles over food, housing, aquifer contamination, air pollution, conservation space, safety, and farmland, the study proposes that a new materialist approach combining emerging transdisciplinary fields that focus on material flows and metabolism offers a big-picture science for landscape diagnostics and repair. It is argued that the Earth processes such as metabolism, thermodynamics, and flow offer an integrative basis for environmental governance based on partnerships with Earth processes. Such a constitutional shift in approaches to local governance offers the possibility of amplifying habitability without inserting new modes of profit-taking into the web of life.

A process perspective of conceptual innovation: Integrating equity in applications of the ecosystem services concept in Ireland

The ecosystem services (ES) concept emerged as a metaphor to demonstrate humanity’s dependence on the natural environment and is increasingly applied to frame human-nature relationships in conservation science, policy and practice. This paper aims to enhance understanding of how the ES concept is applied for ecosystem management and biodiversity conservation in the Irish context, with further applicability to international contexts. Semi-structured interviews were conducted with stakeholders involved in ES research, policy and practice to understand and reflect a variety of perspectives. Three contexts of ecosystem management in Ireland are examined as focal points for the ES framing: natural capital and ES research; Agri-Environment schemes as types of Payments for ES; and collaborative forms of governance for peatland conservation. Specifically, we examine the idea of conceptual innovation as a process where concepts evolve in time and space as they are applied by different societal actors. The contexts examined demonstrate a variety of perceptions and show the scope for agency in how concepts are applied when they meet local realities. The research also demonstrates how alternative concepts and ideas are continuously emerging in societal discourse, and suggests the need to develop ‘networks of concepts’ that can work together to manage the politics, power relations and inequities inherent in the application of any concept. Fostering transparency and reflection on values, language and how knowledge is produced helps make visible power dynamics underlying the ES concept and encourages the development of ES approaches that are effective, inclusive and actionable. Developing concepts from a process perspective has implications for changing the course of a concept as its future unfolds. Following from this, we suggest the need to map an emancipatory future agenda for ES research that centres the voices of those researching, participating and acting ‘from the margins’.

A shift from individual species to ecosystem services effect: Introducing the Eco-indicator Sensitivity Distribution (EcoSD) as an ecosystem services approach to redefining the species sensitivity distribution (SSD) for soil ecological risk assessment.

Incorporating the ecosystem services (ES) approach into soil ecological risk assessment (ERA) has been advocated over the years, but implementing the approach in ERA faces some challenges. However, several researchers have made significant improvements to the soil ERA, such as applying the species sensitivity distribution (SSD) to discern chemical effects on the soil ecosystem. Despite the considerable contributions of SSD to ERA, SSD fails to relate chemical impact on individual species to ES and account for functional redundancy as well as soil ecosystem complexity. Here, we introduce the Eco-indicator Sensitivity Distribution (EcoSD). An EcoSD fits ecological functional groups and soil processes, termed "eco-indicators," instead of individual species responses to a statistical distribution. These eco-indicators are related directly to critical ecosystem functions that drive ES. We derived an EcoSD for cadmium as a model chemical and estimated a soil ecosystem protection value (EcoPVSoil) based on the eco-indicator dataset for cadmium from the literature. The EcoSD identified nitrogen cycling as the critical process disrupted by cadmium. A key advantage of EcoSD is that it identifies key ecological and chemical indicators of an ES effect. In doing so, it links chemical monitoring results to sensitive ecological functions. The estimated EcoPVSoil for cadmium was slightly more protective of the soil ecosystem than most regional soil values derived from this study's dataset and soil guideline values from the literature. Thus, EcoSD has proven to be a practical and valuable ES concept with the potential to serve as an initial step of the tiered ERA approach.

Mapping the knowledge of ecosystem service-based ecological risk assessment: scientometric analysis in CiteSpace, VOSviewer, and SciMAT

The ecosystem services approach offers a more ecologically relevant method to establish environmental conservation goals and implement ecological risk assessment (ERA). The emergence of bibliometrics has facilitated the development of new systematic review techniques. In this study, we utilised CiteSpace, VOSviewer, and SciMAT software, based on the Web of Science database, to qualitatively and quantitatively analyse the ecosystem service-based ecological risk assessment (ESRA) literature knowledge map spanning from 1994 to 2023. This article explored the field’s evolution from macro to micro perspectives, incorporating background information, current trends, and knowledge structure. The findings demonstrate that ESRA has progressed from an initial stage to a phase of global cooperation and policy applications. This transition between stages has been characterised by a shift from focusing on natural processes to understanding human impacts on ecosystems. Key themes identified include ecosystem services, landscape ERA, aquatic ERA and ecosystem health. The overall development of ERA can be observed as a progression through different periods, namely, the traditional era, regional era, and landscape era. Currently, landscape ERA methods based on changes in land use and land cover are widely employed. The study also revealed various challenges in the ESRA field, such as data availability, scale issues, and uncertainty. Future ESRA studies should consider holistic ecosystem services, interdisciplinary approaches, ecological models, and advanced technologies to address complexity. Using big data and informatisation for research offers new opportunities but requires integration and innovation. It is anticipated that ESRA holds promise for ecological sustainability and human wellbeing.

Conceptualizing ‘green’ in urban and regional planning – the cases of Oslo and Helsinki

ABSTRACTIn recent decades, nature has been increasingly acknowledged in the urban environment for its importance to people’s well-being and quality of life, as well as for its role in building sustainable cities. The idea of nature in cities and the conceptualization of ‘green’ (e.g. green structure, green fingers, green infrastructure, parks and ecosystem services) are correlated in planning approaches. This study explores the conceptualization of green by analysing the concepts used in the two regions of Oslo and Helsinki, and by investigating their current master and regional plans through quantitative and qualitative analyses. The findings exhibit a variety of green concepts and complementary features (between planning concepts introduced earlier and newer ones). Over the years, and in the light of evolving ideas of nature, the master and regional plans of both regions have set up a multi-functionality framework, more recently influenced by ecosystem services approaches. The study contributes to understanding the evolving conceptualization of green in urban and regional planning approaches. The discussion is linked to place-specific contexts and regulatory practices, and connected – to some extent – to the wider international debate and planning ideas that incorporate nature.
