Nature‐Based Solutions for Europe's Sustainable Development
Pursuing economic targets of job creation, growth, and innovation while tackling global environmental challenges, has long been seen as impossible. However, any long‐term economic competitiveness and security depends on the extent to which natural resources are used sustainably. Therefore, the European Union is investing in nature‐based solutions to achieve this double goal. The difference between the prevailing economic model and a sustainable resource use has long seemed insurmountable. While many debates are paralyzed or radicalized, nature‐based solutions could offer a transition path with realistic, incremental steps toward a sustainable economy as envisaged by the EU Horizon 2020 vision. This paper outlines the basics of a nature‐based scenario for Europe, and proposes criteria to focus, guide, and evaluate the implementation of nature‐based solutions, geared at production of wide socioeconomic benefits, provision of jobs, and low‐carbon technology innovations.
Soybean Trade: Balancing Environmental and Socio-Economic Impacts of an Intercontinental Market
The trade in soybean, an important animal feed product, exemplifies the environmental and socio-economic impact of global markets and global agricultural policy. This paper analyses the impact of increasing production of soybean in the exporting countries (deforestation and grassland conversion) as well as in importing regions (decrease in permanent grassland by substitution of grass as feed). Ecosystem services monetary values were used to calculate the environmental and socio-economic impact of observed land use changes. This is balanced against the economic value of the global soybean trade. The results prove that consumption choices in one region have real effects on the supply of ecosystem services at a large spatial scale. Conclusively, solutions to make this global market more sustainable are discussed.
Measuring ecosystem multifunctionality across scales
Multifunctionality refers to the capacity of an area to supply multiple ecosystem functions or services. While many conceptual and methodological advances have focused on defining and quantifying multifunctionality, the challenge of dealing with cross-scale dynamics of multifunctionality remains open. This study proposes a new way of measuring multifunctionality across spatial scales, illustrated with a European-wide dataset of 18 ecosystem services. Our assessment captures not only the diversity of ecosystem services supplied within each municipality (alpha-multifunctionality), but also the unique contribution of each municipality to the regional ecosystem service diversity (beta-multifunctionality). This cross-scale analysis helps better understanding the spatial distribution of ecosystem services, which is required to design management and policies at the right scale. Our analysis shows that alpha-multifunctionality follows a latitudinal gradient across Europe and strongly decreases towards the city centers of metropolitan areas. By relating alpha- and beta-multifunctionality to land use intensity, we show that low-intensity management systems support higher ecosystem multifunctionality across Europe. Municipalities of low alpha-multifunctionality often contribute significantly to regional multifunctionality, by providing ecosystem services of a specific value to the region. Our method to measure both alpha- and beta-multifunctionality thus provides a new way to inform reconciliation of competing land uses when maximizing alpha-multifunctionality is not reasonable.
Keep it real: selecting realistic sets of urban green space indicators
With increasing urbanisation, urban green spaces are expected to be crucial for urban resilience and sustainability, through the delivery of ecological, economic and social benefits. In practice, however, planning, management and evaluation of urban green spaces are rarely structured and evidence-based. This represents a missed opportunity to account for, track and foster the multiple benefits that green spaces are expected to deliver. To gain insight into this gap, this study assesses the availability and uptake of relevant evidence by city governments. Interviews, focus groups and quantitative surveys were applied in four medium-sized European cities: Coimbra (Portugal), Genk (Belgium), Leipzig (Germany), and Vilnius (Lithuania), covering the main governance and climatic gradients in Europe. Using straightforward data exploration and regression, we analyse which ecological, economic and social indicators are typically chosen by cities and why. Together with the city stakeholders, we derived a common set of benefit categories and key performance indicators which can be adapted to diverse local contexts. We conclude that cities tend to make pragmatic decisions when composing their indicator sets, but nevertheless cover multiple urban green space dimensions. Finally, we explore how indicator choice could be optimised towards a complementary and credible indicator set, taking into account a realistically feasible monitoring effort undertaken by the cities.
Why do we work together? Motivations for collaboration in multifunctional conservation-oriented landscapes
Around the world, many environmental and social problems often appear together, such as biodiversity loss, soil degradation, and livelihood precarity. Integrated landscape approaches have emerged as a powerful way to tackle these intertwined crises at the scale of whole landscapes, but success depends on a factor often overlooked: the motivation of people to collaborate. The objective of this study is to review and synthesize the available scientific evidence of the reasons why actors choose to collaborate in multifunctional protected landscapes. Building on existing literature, we developed an analytical framework that views collaboration as a dynamic interplay between actor-level motivators (ranging from non-material relations to nature, community or organizational ties, to material benefits) and network-level motivators (shared goals, interdependence, trusted networks, effective interactions, and clear achievements). These drivers are further shaped by broader forces such as agency, legal frameworks, social and political context, the socioeconomic conditions, and biophysical contexts. Our findings reveal a crucial insight: sustainable collaboration cannot rest on a single motivator, such as financial gain, but thrives when a “bundle of motivators” is activated. To help organizations unlock this potential, we identify seven practical levers to strengthen collaboration and maximize the impact of integrated landscape approaches. By understanding and intentionally fostering these layered motivations, landscape management can move from fragmented efforts to transformative, long-term solutions for both people and nature.
Participatory identification and selection of ecosystem services: building on field experiences
The concept of ecosystem services (ESs) has become a popular tool for science that aims to support decision making for sustainable management of natural resources. With the aim to integrate nature’s diverse values in decisions and to reach effective actions, it is recommended that valuations begin with a participatory identification of the most relevant ESs to be included in the assessment. Despite being a crucial step directly influencing decision making, experiences of researchers with real-life applications are seldom reported. Our aim is to advance the organization and implementation of participatory ES identification and selection by providing a self-reflective description and discussion of 5 case studies (CSs). A self-evaluation workshop was organized among the researchers involved in the CSs to gather factors of success and failure encountered throughout the process. From this reflection, we suggest a list of 11 recommendations. We use a wide range of the literature on participatory research evaluation to guide our reflection and demonstrate the relevance of participatory science to the field of ESs. Reflexivity proved to be an essential aspect of sharing lessons learned and advancing methodology toward real-life impact.
Synthesizing plausible futures for biodiversity and ecosystem services in Europe and Central Asia using scenario archetypes
Scenarios are a useful tool to explore possible futures of social-ecological systems. The number of scenarios has increased dramatically over recent decades, with a large diversity in temporal and spatial scales, purposes, themes, development methods, and content. Scenario archetypes generically describe future developments and can be useful in meaningfully classifying scenarios, structuring and summarizing the overwhelming amount of information, and enabling scientific outputs to more effectively interface with decision-making frameworks. The Intergovernmental Platform for Biodiversity and Ecosystem Services (IPBES) faced this challenge and used scenario archetypes in its assessment of future interactions between nature and society. We describe the use of scenario archetypes in the IPBES Regional Assessment of Europe and Central Asia. Six scenario archetypes for the region are described in terms of their driver assumptions and impacts on nature (including biodiversity) and its contributions to people (including ecosystem services): business-as-usual, economic optimism, regional competition, regional sustainability, global sustainable development, and inequality. The analysis shows that trade-offs between nature's contributions to people are projected under different scenario archetypes. However, the means of resolving these trade-offs depend on differing political and societal value judgements within each scenario archetype. Scenarios that include proactive decision making on environmental issues, environmental management approaches that support multifunctionality, and mainstreaming environmental issues across sectors, are generally more successful in mitigating trade-offs than isolated environmental policies. Furthermore, those scenario archetypes that focus on achieving a balanced supply of nature's contributions to people and that incorporate a diversity of values are estimated to achieve more policy goals and targets, such as the UN Sustainable Development Goals and the Convention on Biological Diversity Aichi targets. The scenario archetypes approach is shown to be helpful in supporting science-policy dialogue for proactive decision making that anticipates change, mitigates undesirable trade-offs, and fosters societal transformation in pursuit of sustainable development.
Indicators for relational values of nature’s contributions to good quality of life: the IPBES approach for Europe and Central Asia
Relational values are values of desirable relationships between people and nature and amongpeople (through nature). We report on the approach to capture relational values of nature’scontributions to people in the regional assessment for Europe and Central Asia of theIntergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES).We present a framework considering indicators along four relational value dimensions aboutpeople’s relationships with nature: security and sovereignty; health; equity and justice; andheritage, social identity and stewardship. The framework has been operationalized for threenature’s contributions to people (NCP): regulation of freshwater quality and quantity, foodand feed, and physical and psychological experiences derived from nature. We identify waysto empirically assess relational values of nature’s contributions to people at regional andcontinental scales with social-ecological indicators and proxies, ranging from biophysicalindicators to indicators that intersect socio-economic with biophysical data. We concludethat many of the identified indicators can be considered as useful proxies of relational valuesin a quantitative way. The analysis shows that relational values are essential to consider at thescience-policy interface as they are an important set of values that people hold about natureand that go beyond instrumental relations.
Advancing research on ecosystem service bundles for comparative assessments and synthesis
Social-ecological interactions have been shown to generate interrelated and reoccurring sets of ecosystem services, also known as ecosystem service bundles. Given the potential utility of the bundles concept, along with the recent surge in interest it is timely to reflect on the concept, its current use and potential for the future. Based on our ecosystem service bundle experience, expertise, and ecosystem service bundle analyses, we have found critical elements for advancing the utility of ecosystem service bundle concept and deepening its impact in the future. In this paper we 1) examine the different conceptualizations of the ecosystem service bundle concept; 2) show the range of benefits of using a bundles approach; 3) explore key issues for improving research on ecosystem service bundles, including indicators, scale, and drivers and relationships between ecosystem services; and 4) outline priorities for the future by facilitating comparisons of ecosystem service bundle research.
Mapping wetland loss and restoration potential in Flanders (Belgium)
With the case of Flanders (northern part of Belgium) we present an integrated approach to calculate accurate losses of wetlands, potentials for restoration, and their ecosystem services supplies and illustrate how these insights can be used to evaluate and support policy making. Flanders lost about 75% of its wetland habitats in the past 50–60 years, with currently only 68,000 ha remaining, often in a more or less degraded state. For five different wetland categories (excluding open waters) we calculated that restoration of lost wetland is still possible for an additional total area of about 147,000 ha, assuming that, with time and appropriate measures and techniques, the necessary biophysical and ecological conditions can more or less be restored or created. Wetland restoration opportunities were mapped according to an open and forested landscape scenario. Despite the fact that for 49,000 ha wetland restoration is justifiable by the actual presence of an appropriate spatial planning and/or protection status, the official Flemish nature policy only foresees 7,400 to 10,600 ha of additional wetland (open waters excluded) by 2050. The benefits of a more ambitious wetland restoration action program are underpinned by an explorative and quantified analysis of ecosystem service supply for each of the two scenarios, showing that the strongly increased supply of several important regulating and cultural ecosystem services might outweigh the decrease of food production, especially if extensive farming on temporary wet soils remains possible. Finally, we discuss the challenges of wetland restoration policies for biodiversity conservation and climate change.
