Intrinsic, instrumental and relational values behind nature’s contributions to people preferences of nature visitors in Germany

ABSTRACT Protected areas not only provide biodiversity conservation but also offer a multitude of nature’s contributions to people (NCP), such as recreational opportunities. Visitors to these areas value nature and NCP for various reasons, potentially leading to different arguments for conservation planning. So far, research has neglected the heterogeneity of reasons why visitors value nature and NCP in natural areas. In this study, we identified NCP preferences and elicited diverse values underpinning those preferences, i.e. intrinsic, instrumental and relational values. We analysed 127 semi-structured interviews with nature visitors of three regions encompassing protected areas across Germany including Schorfheide-Chorin (North East), Hainich-Dün (Central), and Schwäbische Alb (South West). We found that relational values resonated more broadly than intrinsic and instrumental values. We also found a connection between NCP preferences and the values underpinning them: regulating NCP were mostly associated with care and stewardship, instrumental values and social responsibility. In contrast, non-material NCP were mostly associated with therapeutic values and aesthetic values. Moreover, we found that socio-demographic factors – i.e. age, gender, income, education – and sustainable consumption patterns influenced the expression of different values. For instance, intrinsic values resonated more broadly for women than for men. We showed geographic differences in NCP preferences and their corresponding values across the regions. The results show that NCP values and preferences can be diverse within stakeholder groups and that research approaches need to be chosen carefully to be able to reveal this diversity. We conclude that value pluralism is fundamental to understanding underlying mechanisms in NCP research.

Degrowth scenarios for biodiversity? Key methodological steps and a call for collaboration

AbstractStudies show that economic growth contributes to biodiversity loss and that, after a certain threshold, it does not contribute to wellbeing. Thus, when developing biodiversity scenarios, considering societal futures where economic growth is not a pre-condition deserves special attention. However, to date, degrowth scenarios have not been explored for biodiversity conservation and human wellbeing. In this paper, we explain how the Nature Futures Framework (NFF) and other approaches could be used to generate degrowth scenarios for biodiversity, nature’s contributions to people (NCP) and good quality of life (GQL) based on multiple societal values. We present key methodological steps of such an endeavour, including: (i) producing degrowth visions for high-income countries; (ii) identifying leverage points and imagining degrowth pathways; (iii) identifying key social–ecological interactions; and (iv) modelling biodiversity, NCP, and GQL along degrowth scenarios. Our proposal is framed within current theoretical, empirical, and modelling work as well as within efforts to improve scenario development across the biodiversity and climate communities. To develop degrowth scenarios for biodiversity, NCP, and GQL, we call for collaboration across natural and social sciences, quantitative and qualitative approaches, and northern and southern perspectives. This collaboration could lead to a community of practice that tests and improves the degrowth scenarios in national and international science–policy interfaces as they set out to achieve the Convention on Biological Diversity’s 2050 vision of living in harmony with nature.

Nature's contributions to human well‐being under climate change: Evidence from Central and Eastern Madagascar

Abstract Anthropogenic climate change has an unprecedented impact on ecosystems and their services, with severe consequences for human well‐being, particularly for the marginalised and vulnerable members of society in the Global South. The well‐being of communities relies not only on material and regulating services ecosystems provide but also on non‐material services. In this paper, we unravel the diverse ways that climate change impacts affect Nature's Contributions to People (NCP) and the well‐being of rural populations in four sites in Madagascar—a biodiversity hotspot but one of the economically poorest countries in the world. We conducted participatory community workshops, mapping and semi‐structured interviews with local residents across social subgroups to understand the mechanisms of climate‐related degradation and the resulting impacts on different dimensions of human well‐being through an NCP lens. We found that non‐material services are generally more often associated with well‐being effects. Climate change degrades material and non‐material services through sea level rise, biodiversity loss, drought, precipitation and temperature variability, with consequences for materials, companionship and labour, food and feed, and physical and psychological experiences. Loss of land and forests is expressed through ecological grief. The outcome of our research provides evidence‐based information to local policymakers, conservation practitioners, and climate change agencies. This information can help improve government efforts toward holistic conservation and climate change adaptation by addressing the impacts on the physical and mental well‐being of the most vulnerable communities.

A quantitative framework for identifying the role of individual species in Nature's Contributions to People.

It is widely acknowledged that biodiversity change is affecting human well-being by altering the supply of Nature's Contributions to People (NCP). Nevertheless, the role of individual species in this relationship remains obscure. In this article, we present a framework that combines the cascade model from ecosystem services research with network theory from community ecology. This allows us to quantitatively link NCP demanded by people to the networks of interacting species that underpin them. We show that this "network cascade" framework can reveal the number, identity and importance of the individual species that drive NCP and of the environmental conditions that support them. This information is highly valuable in demonstrating the importance of biodiversity in supporting human well-being and can help inform the management of biodiversity in social-ecological systems.

Urban pondscape connecting people with nature and biodiversity in a medium-sized European city (Geneva, Switzerland)

AbstractThe current progressive increase in urbanisation is a contributing factor to the alarming rate of decrease in biodiversity worldwide, so it is critical to propose new solutions that bring nature, and their associated benefits, back to cities. Urban ponds and pondscapes are potential Nature-based Solutions that play a crucial role in the conservation and promotion of biodiversity, as well as providing other ecosystem services. Therefore, it is important to understand people's perception of the contribution that these ponds/pondscapes make in their daily lives. The aim of this study was to assess public perception of the value of the multiple ecosystem services, here referred to as Nature's Contributions to People (NCPs), provided by urban ponds with a focus on biodiversity. To achieve it, we conducted a face-to-face questionnaire survey among 331 visitors of urban parks and nature reserves in a medium-sized European city (Geneva, Switzerland). The results show that people highly value the different contributions provided by urban ponds, and that contact with nature is the main motivation for visiting urban pondscapes. Their positive view about the provided NCPs and also their acknowledgement of an improved quality of life suggest a public acceptance of these ponds. We also found that gender and income do not influence public perception of the contributions provided by urban pondscapes. Additionally, the biodiversity of urban ponds was highly appreciated, but there was a knowledge gap relating to biodiversity conservation, as both native and exotic species were valued equally. In conclusion, ponds are Nature-based Solutions that are very well adapted and accepted in cities, and in the future they should be part of the greening (and blueing) of urban planning to conserve and enhance freshwater biodiversity whilst also providing NCPs.

Nature's contributions to people responding to landscape stability in a typical karst region, southwest China

Understanding the response of nature's contributions to people (NCP) to change in landscape stability may constrain and guide human modification of nature. However, the effects of landscape stability on NCP, in the context of active human modification, remain unclear. To address this issue, we chose the Wujiang River Basin in the Yangtze River Economic Belt of China as a study area and quantified landscape stability in 2000, 2010, and 2020 under different scenarios. Environmental protection and comprehensive development scenarios were simulated for 2030 using the patch-generating land use simulation (PLUS) model. For current and future scenarios, NCP were assessed in terms of indicators, which included habitat creation and maintenance (NCP1), regulation of freshwater (NCP6), and protection of soils (NCP8). Under the current status quo, urban expansion was 491.547 km2, and landscape stability showed a decreasing trend, with the mean value decreasing from 0.049 in 2000 to 0.015 in 2020. In future scenarios, landscape stability was highest under the comprehensive development scenario. In addition, in terms of changes in NCP, the high-value contributions declined by 16%–48% from 2000 to 2020. Our results clarified how NCP respond to landscape stability. These results can help conservation managers develop more targeted ecological strategies that will constrain human modification activities to enhance well-being.

Governing anthropogenic assets for nature’s contributions to people in forests: a policy document analysis

Forests support human wellbeing by providing multiple nature’s contributions to people (NCP). These are derived from an interplay of both natural and anthropogenic assets, which is a process known as NCP co-production. Like forests and NCP, anthropogenic assets are subject to modes of governance operating across multiple levels, in which policies are a central tool for executing formal governance. Here, we conduct a policy document analysis to investigate how policies refer to both the anthropogenic assets involved in NCP co-production and the modes of governance affecting these, i.e., hierarchical, scientific-technical, (adaptive)-collaborative governance, and the governing of strategic behaviour. The policy document analysis focuses on forestry and biodiversity conservation policies spanning across multiple governance levels, from the local level – two Biosphere Reserves and one National Park in Germany – to the supra-national level of the European Union. We find that policies predominantly address material and regulating NCP and refer to hierarchical and scientific-technical governance. Based on a redundancy analysis, we identify six archetypes of governance of NCP and the anthropogenic assets underpinning their co-production: (1) the governing of strategic behaviour for regulating NCP, (2) governing habitat management for experiences in nature, (3) governing habitat management for pest control, (4) collaborative governance for timber, (5) local governance for experiences in nature, and (6) promoting knowledge for habitat protection. Our analysis thereby unveils how policies intend to govern anthropogenic capitals related to the co-production of specific forest NCP. The findings, including the six archetypes, can support policymakers in designing policies across governance levels.

Co-production of nature’s contributions to people in dry rivers: a case study in Murcia, Spain

ABSTRACT Dry rivers are non-perennial rivers with no surface water in their channels except after heavy rainfall or snowmelt. The lack of water flow is often associated with a low provision of Nature’s Contributions to People (NCP) and a poor quality of life. However, recent review studies have found evidence of human communities thriving in dry rivers through the co-production of multiple NCP, although no case studies have yet confirmed this evidence. We assessed the capacity of dry rivers and their associated social systems to provide NCP. We selected three dry rivers with high natural, cultural and landscape values in the most arid part of Murcia (Spain). We interviewed 37 representatives of the most influential social groups in the study area to explore the NCP of dry rivers, their synergies and trade-offs. Four material, three non-material and eight regulating NCP were identified, as well as one unique NCP: access to villages and fields through dry riverbeds. Fifty-two synergies were identified, especially between material and non-material NCP, and eight trade-offs. This wide range of NCP and synergies is a consequence of the co-production processes between dry rivers and the social system. NCP co-production seems to be underpinned by the indigenous and local knowledge acquired by the social system over generations about the management of floodwaters, biodiversity and geodiversity. Incorporating this knowledge into research and governance can help raise awareness of the NCP provided by dry rivers and help develop strategies for mitigating and adapting to global change.

Archetypes of social-ecological-technological systems for managing ecological infrastructure

The concept of ecological infrastructure (EI) as a lens for landscape management has the potential to address environmental challenges, such as biodiversity loss and ecosystem degradation, by instrumentalizing Nature’s Contributions to People (NCP). NCPs stems from the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) and refers to the various ways in which the natural world provides benefits, values, and services that directly and indirectly contribute to the well-being, livelihoods, and cultural aspects of human societies. This research explores this potential by proposing an archetype analysis of social-ecological-technological systems (SETS) to manage EI. We derived archetypes using machine learning and clustering on a data-driven SETS framework co-produced with experts in EI management. The archetype analysis was conducted by combining K-means with hierarchical clustering on spatial patterns to generate clusters with similar configurations of social, ecological, and technological subsystems. The approach is illustrated for the canton of Geneva, Switzerland, which experiences high urbanization and ecological pressures. The resulting spatially explicit archetypes of SETS facilitate policy recommendations tailored to multifunctional landscapes, which can be used to derive coherent management strategies for EI. In addition, the approach demonstrates that by taking an integrated landscape approach and engaging with diverse stakeholders, it is possible to develop effective landscape-based management recommendations for promoting the sustainable provision of NCPs and biodiversity within the concept of EI.

Participatory mapping of local stakeholders’ perceptions of nature’s contributions to people in an intensified agricultural area in the Colombian Andes

ABSTRACT Intensification of agricultural land use in traditional Andean production landscapes has led to changes in the provision of nature’s contributions to people (NCP) that can threaten people’s wellbeing. Understanding local stakeholders’ valuation of these NCP is crucial for improving land use decisions. We implemented a spatially explicit and participatory NCP valuation method, using semi-structured interviews and participatory mapping, followed by a spatial multi-criteria decision analysis, to identify priority areas for NCP provision in a highly intensified production landscape in the Colombian Andes. We considered multiple value types, ecological, economical and sociocultural, and the points of view of different actors, orienting this towards decision-making on land use. Our results show that local actors can identify and value a wide range of NCP. However, there are also significant differences between actors. Environmentalists attached special importance to regulating NCP, while agricultural laborers focused more on agriculture-related material NCP. As we expected, tourism entrepreneurs especially valued non-material NCP related to their business experiences. Small-scale farmers tended to put more importance on regulating and non-material NCP than big farmers did. Although there was a consensus between actors as to the importance of natural ecosystems for NCP provision, agricultural actors tended to attach more importance to material NCP in areas deemed important for regulating and non-material NCP by other actors. Our main results confirm the importance of involving different stakeholders in spatial NCP valuation exercises, recognizing their different points of view to help identify possible trade-offs and synergies related to land use.

Knowledge coproduction to improve assessments of nature's contributions to people.

Sustainability science needs new approaches to produce, share, and use knowledge because there are major barriers to translating research into policy and practice. Multiple actors hold relevant knowledge for sustainability including indigenous and local people who have developed over generations knowledge, methods, and practices that biodiversity and ecosystem assessments need to capture. Despite efforts to mainstream knowledge coproduction, less than 3% of the literature on nature's contributions to people (NCP) integrates indigenous and local knowledge (ILK). Approaches and tools to better integrate scientific and ILK knowledge systems in NCP assessments are urgently needed. To fill this gap, we conducted interviews with ILK experts from Abancay and Tamburco, Peru, and convened focus groups and workshops during which participatory mapping, a serious game, a Bayesian belief network based on ILK were introduced. We inventoried 60 medicinal plants used to treat different illnesses, and analyzed the spatial distribution of the 7 plants that contribute the most to a good quality of life, and delineated their nonmedicinal uses. Based on the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services conceptual framework, we defined dimensions of a good quality of life according to indigenous and local worldviews. Medicinal plants contributed strongly to health and household security, among other contributions. Climate change and overexploitation were the main perceived threats to medicinal plants, despite the existence of formal and customary institutions to regulate trade. Our approach was flexible enough to integrate diverse forms of knowledge, as well as qualitative and quantitative information from, for example, the Bayesian belief network.

How to synergize ecological restoration to co-benefit the beneficial contributions of nature to people on the Qinghai-Tibet Plateau?

Understanding the magnitude and spatial distribution of ecological restoration requires a precise assessment of the beneficial contributions of nature to people. However, where the restoration areas should be located and whether the natural contribution of a compensation area can satisfy people's needs in the context of ecological degradation remain unclear. To address these issues, we selected the Qinghai-Tibet Plateau as the study areas, utilizing the offset portfolio analyzer and locator model to identify the compensation sites that offset the losses of ecosystem services and biodiversity resulting from ecological degradation. These compensation sites were developed through two offset types: restoration and protection. Then, based on the offset sites, we assessed nature's contribution to people (NCP) under the current status and future scenarios in terms of various aspects, including the habitat (NCP1), climate change (NCP4), and water quantity and flow regulation (NCP6). This study found that the area impacted by agricultural development was 7.15 × 105 ha, and the required compensation area was 5.5 × 106 ha under the current status. The ratio of the impacted area to the required area was approximately 7.0 in the future scenarios. The average habitat qualities were 0.14 and 0.30, while the mean NCP1 values were 2.69 and 0.51 in the protection and restoration offset sites, respectively. Moreover, based on the offset sites, the high-value contributions in NCP4 accounted for 18.64%–22.69% and 38.87%–46.17% of the total offset sites in terms of the restoration and protection offset types, respectively. Additionally, the estimated high-value contributions in NCP6 accounted for 58.35%–59.02% and 84.40%–95.86% of the total offset sites in the restoration and protection offset types, respectively. Our findings highlighted the significance of ecological restoration in showcasing the role of NCPs. These results could aid conservation managers in developing more targeted ecological strategies to enhance human well-being.

Linking seed networks and crop diversity contributions to people: A case study in small-scale farming systems in Sahelian Senegal

CONTEXTSmall farms rely on a range of nature's contributions to people (NCPs) provided by crop diversity, covering both material and immaterial dimensions that are crucial for livelihoods and well-being. The maintenance of these NCPs over time, despite perturbations, is a key component of small farms' resilience. However, the processes involved in farmers accessing the different NCPs provided by crops are largely unknown. Such knowledge would be instrumental for evaluating the vulnerability or resilience of farmers to potential disruptions that affect these distribution channels. OBJECTIVEIn this study, we analyzed how the seed provisioning networks used by farmers to access crops relate to the different NCPs they receive from these crops, through a case study in Sahelian Senegal. METHODSField surveys were conducted with 85 farmers, half men and half women, from two villages. The surveys documented which varieties of three important staple crop species (pearl millet, cowpea, peanut) farmers grew. Farmers were asked to cite their motivations for cultivating each variety as a proxy for NCPs, and to explain from where they obtained the seeds of each variety of these three species. We mobilized recent developments in Social-Ecological Network research, representing the relationships between social entities (i.e., farmers and seed sources), ecological entities (i.e., crops), and NCPs (i.e., motivations) as networks. We applied a block model clustering approach to analyze these relationships by testing if particular seed sources were associated with particular motivations, and if differences existed between men and women. We also analyzed households' profiles according to the motivations they cited and the seed sources they were connected to. RESULTS AND CONCLUSIONSWe found that some crops contributions were related to different seed sources, for instance crops associated to food provision were sourced through markets, peers, and legacy, while other contributions were related to one seed source type, for instance crops associated to attachment were sourced exclusively through legacy. Women relied on a more limited pool of seed sources than men, and they preferentially source seeds from peers. Last, two groups of households were differentiated based on the number of crops contributions and of seed sources they mentioned. SIGNIFICANCEOur study brings insights on how the observed social-ecological network patterns affect the access of men and women farmers to NCPs, and the consequences for the maintenance of NCP provision in the face of perturbations. It contributes to unraveling the processes involved in the resilience of small farms that rely on crop diversity for their livelihoods.

Indicators to monitor the status of the tree of life.

Following the failure to fully achieve any of the 20 Aichi biodiversity targets, the future of biodiversity rests in the balance. The Convention on Biological Diversity's Kunming-Montreal Global Biodiversity Framework (GBF) presents the opportunity to preserve nature's contributions to people (NCPs) for current and future generations by conserving biodiversity and averting extinctions. There is a need to safeguard the tree of life-the unique and shared evolutionary history of life on Earth-to maintain the benefits it bestows into the future. Two indicators have been adopted within the GBF to monitor progress toward safeguarding the tree of life: the phylogenetic diversity (PD) indicator and the evolutionarily distinct and globally endangered (EDGE) index. We applied both to the world's mammals, birds, and cycads to show their utility at the global and national scale. The PD indicator can be used to monitor the overall conservation status of large parts of the evolutionary tree of life, a measure of biodiversity's capacity to maintain NCPs for future generations. The EDGE index is used to monitor the performance of efforts to conserve the most distinctive species. The risk to PD of birds, cycads, and mammals increased, and mammals exhibited the greatest relative increase in threatened PD over time. These trends appeared robust to the choice of extinction risk weighting. EDGE species had predominantly worsening extinction risk. A greater proportion of EDGE mammals (12%) had increased extinction risk compared with threatened mammals in general (7%). By strengthening commitments to safeguarding the tree of life, biodiversity loss can be reduced and thus nature's capacity to provide benefits to humanity now and in the future can be preserved.

Inequity in nature’s contributions to people in Ōtautahi/ Christchurch: A low-density post-earthquake city

Nature’s contributions to people (NCP) include the regulating, material, and non-material benefits of urban vegetation that improve well-being. It is increasingly important to plan cities that provide multiple types of NCP equitably to all residents of the city. However, due to historical legacies and planning policies, it is common for the most socially and economically vulnerable urban residents to suffer reduced access to the benefits of urban ecosystems. Previous studies of urban NCP have drawn attention to inequity in one or several types of NCP, but few have analysed a broad range. Here we analysed inequity in nine diverse forms of urban NCP across an index of economic and social vulnerability designed specifically to characterise vulnerability to environmental pressures. Furthermore, we used spatial analysis to map co-variance in vulnerability and a composite indicator of urban NCP, thus highlighting priority regions for future investments in green infrastructure. We applied this approach to the city of Christchurch/ Ōtautahi in Aotearoa/ New Zealand, which provides a valuable case study due to its multicultural population and recent history of widespread damage and regeneration following the 2011 earthquake. Overall, the distribution of urban NCP is inequitable to the disadvantage of more vulnerable residents. Residents of more vulnerable neighbourhoods experienced reduced provision of carbon stock, runoff retention, air quality enhancement, shade, educational green space, public outdoor space accessibility, private green space, and bird biodiversity contributions. Conversely, more vulnerable neighbourhoods had greater provision of erosion mitigation (although negligible in magnitude). The wide range of indicators used and assessed in response to vulnerability, coupled with an assessment of the type of vegetation cover (i.e. grass, tall trees) provides greater insights into how inequities in urban NCP can be addressed in future redevelopment.

Operationalizing the Nature Futures Framework for ecological infrastructure

AbstractScenarios are useful for considering development pathways under different future conditions. To manage a functioning ecological infrastructure (EI) as a network of natural and semi-natural habitats that can promote biodiversity and provide nature’s contributions to people (NCPs), one needs to understand future biophysical and socio-economic influences on its development. However, scenarios often do not incorporate the reciprocity of biophysical and societal changes. This has prompted new proposals from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) on the importance of creating nature-centered multiscale scenarios that include a normative dimension accounting for diverse human–nature relationships. In this contribution, we operationalize the Nature Futures Framework (NFF), developed under IPBES, into integrated normative and exploratory scenarios framing the development of a functioning EI in Switzerland until 2060. We follow a two-stage participatory approach methodologically aligned with the IPBES development. First, we elaborated positive visions for future EI with stakeholders in four regions of Switzerland. We then collaborated with experts to create integrated normative and exploratory scenarios through a process comprising literature research, workshops and a survey. By positioning status quo and future scenarios within the Nature Futures Framework, we demonstrate the diversity of nature values in a specific context of EI in Switzerland, thus contributing to the global set of Nature Futures scenarios. Integrating both plausible and desirable developments, these scenarios will serve as a valuable tool in the planning of long-term measures to ensure a functioning EI in Switzerland.

Pluralizing environmental values for urban planning: How to uncover the diversity of imaginaries about socio‐natures from Vitoria‐Gasteiz (Basque Country, Spain)

Abstract Cities have pushed forward re‐naturing initiatives in local planning agendas. Discourses and rationales for such interventions tend to follow instrumental framings often narrowed down to the economic, health and ecological benefits of nature's contributions to people (NCP). Yet, diverse urban residents often connect to other socio‐nature framings that are associated with a plurality of values held for nature, including relational, intrinsic, and instrumental values. Focusing mostly on urban NCP, we used Q‐methodology to explore the perspectives and expressions of urban residents' diversity of values for urban greenery and broader human‐nature relationships. We explore the role of both instrumental and relational values, as well as certain potential disvalues of urban NCP. In light of the recent IPBES values assessment (IPBES, 2022) we follow a call for empirical studies and methodologies to explore, elicit and visibilize plural values about nature. We base our study in the Basque city of Vitoria‐Gasteiz, Spain (2012 European Green Capital) where we identify four distinct perspectives, all of which relate to a diversity of values about urban nature. Urban residents mostly perceive positive values for NCP as directly connected to their wellbeing. Yet, NCP that impact social bonds within their social community, expressed for instance through community‐related values, are perceived differently across the four perspectives. We conclude that planners and decision‐makers should pay scrutiny to include the four, partly differing, perspectives about the plural values of (urban) NCP in policymaking processes to assure just and inclusive outcomes. Here, intersectional and participatory approaches are needed beyond dominating framings of NCPs and related values, especially those that can take into account the needs and preferences of marginalized social groups. Special emphasis should be put on integrating relational values as nourishing such values through planning can play an important role in creating place‐rooted connections with local urban landscapes and the community.

Assessing ambitious nature conservation strategies in a below 2-degree and food-secure world

Global biodiversity is projected to further decline under a wide range of future socio-economic development pathways, even in sustainability-oriented scenarios. This raises the question how biodiversity can be put on a path to recovery, the core challenge for the implementation of the CBD Kunming-Montreal Global Biodiversity Framework. We designed two ambitious global conservation strategies, ‘Half Earth’ (HE) and ‘Sharing the Planet’ (SP), and evaluated their ability to restore terrestrial and freshwater biodiversity and to provide nature's contributions to people (NCP), while also limiting global warming below 2 degrees and ensuring food security. We applied the integrated assessment framework IMAGE with the GLOBIO biodiversity model, using the ‘Middle of the Road’ Shared Socio-economic Pathway (SSP2) with its projected human population growth as baseline. We found that the HE strategy performs generally better for terrestrial biodiversity (biodiversity intactness (MSA), Area of Habitat, Living Planet Index, Red List Index) in currently still natural regions. The SP strategy yields more improvements for biodiversity in human-used areas, for freshwater biodiversity and for regulating NCP (pest control, pollination, erosion control, water quality). However, both strategies were insufficient to restore biodiversity and corresponded with considerable increases in food security risks and global temperature. Only when we combined the conservation strategies with a portfolio of ‘integrated sustainability measures’, including climate change mitigation and reductions of food waste and animal product consumption, our scenarios resulted in a restoration of biodiversity and NCP while keeping global warming below two degrees and food security risks below the baseline projection.

Projected landscape-scale repercussions of global action for climate and biodiversity protection

Land conservation and increased carbon uptake on land are fundamental to achieving the ambitious targets of the climate and biodiversity conventions. Yet, it remains largely unknown how such ambitions, along with an increasing demand for agricultural products, could drive landscape-scale changes and affect other key regulating nature’s contributions to people (NCP) that sustain land productivity outside conservation priority areas. By using an integrated, globally consistent modelling approach, we show that ambitious carbon-focused land restoration action and the enlargement of protected areas alone may be insufficient to reverse negative trends in landscape heterogeneity, pollination supply, and soil loss. However, we also find that these actions could be combined with dedicated interventions that support critical NCP and biodiversity conservation outside of protected areas. In particular, our models indicate that conserving at least 20% semi-natural habitat within farmed landscapes could primarily be achieved by spatially relocating cropland outside conservation priority areas, without additional carbon losses from land-use change, primary land conversion or reductions in agricultural productivity.

Multidimensional Ecosystem Mapping: Towards a More Comprehensive Spatial Assessment of Nature’s Contributions to People in France

Ecosystems are experiencing significant pressure from human activities, with 1 million species at risk of extinction. This is threatening to undermine the resilience of ecosystems, which provide multiple benefits to support human existence and are essential for the support of life on Earth. A number of conceptual frameworks have been developed as a guide for the assessment of ecosystem services (ESs) and nature’s contributions to people (NCPs), including Millennium Ecosystems Assessment, The Economics of Ecosystems and Biodiversity report, France’s National Ecosystems Assessment, the Common International Classification of Ecosystem Services, and the Global Assessment of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. In this paper, we compare the existing conceptual frameworks for the assessment of ESs and NCPs and derive a unified structural framework. Several indicators for characterizing the ESs/NCPs provided are selected and integrated through normalization. On this basis, and enriched by a number of culture-specific indicators, we conduct a mapping exercise illustrating the ES/NCP provision for the whole of France in a spatially explicit form based on a 1 × 1 km scale. Finally, we generate integrated maps depicting distribution patterns of different services and contributions across the landscapes of France focusing on economic, social and ecological dimensions. The results indicate that a non-monetary assessment of the complexity and diversity of NCPs is feasible and presents tangible advantages as compared to monetary frameworks. The paper concludes that provisioning, regulating and cultural services and contributions are geographically unevenly distributed and further analysis is required to assess the degree of complementarity, feedback loops and tipping points among different services. Our pilot research clearly illustrated the feasibility of conducting a highly disaggregated multidimensional assessment of ESs/NCPs at the national scale to inform decision making.
