Integrating spatial patterns and driving factors of cultural ecosystem services into territorial spatial governance: A case study of the Horqin Sandy Land with multi-ethnic settlements

Although the spatial patterns of cultural ecosystem services (CES) are often considered in land use management, there is a noticeable disparity in research coverage compared to biophysical ecosystem services (BES). Moreover, there is a lack of research focusing on human perceptions of CES. To address this gap, this study proposed a CES-BES framework that integrates spatial patterns, driving factors of CES, and their interactions with BES, based on the general framework of social and ecological systems. To alleviate the dual pressures of ecological degradation and cultural preservation, this study utilized the constructed CES-BES framework to offer land use recommendations aimed at promoting sustainable development in the Horqin Sandy Land. CES and BES were quantified through a combination of questionnaire surveys, SolVES model and process modeling, including aesthetic, biodiversity, cultural, economic, future, and historical values, as well as net primary productivity, crop production, wind protection, and sand fixation. The results revealed that CES in the Horqin Sandy Land exhibited a discernible pattern of "high in the west and low in the east." Notably, the factors perceived by respondents exerted a more substantial influence on CES than non-perceptual factors. Female respondents showed relatively lower sensitivity to CES overall, but higher sensitivity to biodiversity. Han respondents tended to prioritize biodiversity, while Mongolian respondents were more sensitive to cultural and historical values. Herders exhibited higher sensitivity to biodiversity, while respondents from other occupations showed higher sensitivity to cultural and future values. The influence of land use, topography, and accessibility on different CES was generally similar. All CES showed a positive correlation with elevation, slope, and distance to water, while they showed a negative correlation with distance to roads. Based on the results, the Horqin Sandy Land has been divided into five regions, with development recommendations provided for each region to ensure sustainable development. This study provides a novel perspective and methodological framework for CES supporting territorial spatial governance and land use management, contributing to a more comprehensive understanding of CES.

Troubled waters: Riparian ecosystem services and community opposition to the largest dam removal project in Europe, Vezins Dam, France

The largest Dam removal project in Europe occurred in 2019 with removal of the Vezins Dam on the Sélune River in Normandy, France. The French State ordered removal of the 36-m high Vezins Dam and the 16-m high la Roche-qui-Boit Dam along the Sélune River to restore ecological and longitudinal connectivity to improve riparian water quality, and especially to restore migratory species of Atlantic salmon (Salmo salar) and eel (Anguilla anguilla). We examine community opposition to removal of the Vezins Dam through the lens of riparian ecosystem services and stakeholder values. Primary data sources includes fieldwork, interviews, and an online survey of local stakeholders. Text analysis and interview coding occurred with ATLAS.ti 22, and highlight themes related to federal-local communication and riparian ecosystem services. The French State ineffectively communicated with local communities regarding dam removal benefits and riparian stakeholder values. While the state focused on biophysical ecosystem services, experiential ecosystem services, such as place attachment, were more important to riparian stakeholders. Often portrayed as a positive benefit, here dam removal lacked community support. Failure of government authorities to effectively incorporate stakeholder values along a continuum of ecosystem services substantially compromises future large-scale federal environmental management projects dependent upon local community support. By examining how local actors experienced dam removal, study results increase understanding of environmental governance and the local consequences of national policy decisions, of use in future dam removal projects – including for large dams – in France and internationally.

Influences of climate change and land use change on the interactions of ecosystem services in China’s Xijiang River Basin

Ecosystem services (ES) emerge from the complex interactions of diverse ecosystem components. In turn, the provision of ES is influenced by how they are put to use and environmental drivers such as climate change and land use change (CC-LUC). Researches into CC-LUC impacts on ES have so far focused on biophysical supply rather than ES interactions, making it difficult to design appropriate strategies for natural capital investment and the consequent ecosystem benefits for human well-being. In this study, we built networks from correlations among climatic forcing, land-use intensity and ES for the Xijiang River Basin in southern China, a rapidly urbanizing region with rich endowments of ecosystem assets. The variations in network structure were evaluated under different climate and land use projections up to 2035. We found that the CC-LUC-ES networks were more sensitive to land use change which affected the network structure either by directly influencing biophysical ES supplies or indirectly through altering ES interactions. Sustainable land-use management (i.e., ecological protection priority scenario) coupled with the RCP4.5 emission scenario showed higher improvements for both water-erosion prevention and regulating services. Whereas increasing land-use intensity (i.e., economic development priority scenario) with RCP8.5 resulted in losses of ES synergies and a more heterogenous network of greater integrity. Our approach provides a comprehensive view of the relationships among multiple ES and how they respond to CC-LUC, which can be applied to advance mechanistic hypotheses for ES variations. The results of this study can inform sustainable management strategies by regulating ES interactions in watersheds.

Cultural ecosystem services caught in a ‘coastal squeeze’ between sea level rise and urban expansion

Sea level rise and urbanization exert complex synergistic pressures on the provision of ecosystem services (ES) in coastal regions. Anticipating when and where both biophysical and cultural ES will be affected by these two types of coastal environmental change is critical for sustainable land-use planning and management. Biophysical (provisioning and regulating) services can be mapped using secondary data. We demonstrate an approach to mapping cultural ES by engaging stakeholders in iterative participatory mapping of personally and communally valuable cultural ES. We identify hotspots where highly valued cultural ES and high values for biophysical ES co-occur and generate spatially-explicit projections of sea level rise and urban expansion through 2060 to quantify impacts of the ‘coastal squeeze’ on ES. We study Johns Island, South Carolina, USA as an example of a vulnerable community in a low-lying region experiencing both rising water levels and a rapid influx of new residents and development. Our projections of environmental change through 2060 indicate that on Johns Island, cultural ES face disproportionately greater risk of decline than biophysical ES, with almost three quarters of the island’s cultural ES affected. We find that hotspots for cultural ES, such as community heritage sites and scenic vistas of oak-lined roads and marshes, rarely co-occur (only 3% area) with biophysical ES such as high values of carbon sequestration and agricultural production. This confirms the importance of engaging with local stakeholders to map cultural ES and puts them on a more level playing field with biophysical ES in decision-making contexts. Projected declines and limited overlap between biophysical and cultural ES highlight the need for tighter coordination between conservation and community planning, and for including locally valued cultural ES in assessments of threats posed by the ‘coastal squeeze’ of sea level rise and urban expansion.

Mapping heritage ecosystem services in ecological restoration areas: A case study from the East Cascades, Washington

Systems-based land management frameworks such as ecosystem services can improve cultural resource management and outdoor recreation in natural areas. We analyzed data from a participatory mapping survey of forest values from an ecological restoration area in the East Cascades, which provide conceptual and methodological tools that can be utilized in land management more widely. We also consulted archaeological, paleo-ecological, and traditional land use data to link heritage values with cultural landscapes. Heritage benefits mapped by respondents were associated with connections to landscapes, sites and resources, and with outdoor recreation. Respondents noted connections to historic vocational identities such as mining and logging, as well as sacred and spiritual activities associated with American Indian Tribes. These heritage connections and benefits were closely tied to natural resources, such as timber, mountains, watersheds, and forest products. In some cases, heritage and biophysical ecosystem services share synergies with regard to potential land management effects, while others would result in tensions or trade-offs for various beneficiaries. Integrated resource management provides a more holistic and informed view of land values that move beyond cultural and biophysical dichotomies, expanding the potential for managing outdoor recreation and heritage.

BESTMAP: behavioural, Ecological and Socio-economic Tools for Modelling Agricultural Policy

Half of the European Union (EU) land and the livelihood of 10 million farmers is threatened by unsustainable land-use intensification, land abandonment and climate change. Policy instruments, including the EU Common Agricultural Policy (CAP) have so far failed to stop this environmental degradation. BESTMAP will: 1) Develop a behavioural theoretical modelling framework to take into account complexity of farmers’ decision-making; 2) Develop, adapt and customize a suite of opensource, flexible, interoperable and customisable computer models linked to existing data e.g. LPIS/IACS and remote sensing e.g. Sentinel-2; 3) Link economic, individual-farm agent-based, biophysical ecosystem services and biodiversity and geostatistical socio-economic models; 4) Produce a simple-to-use dashboard to compare scenarios of Agri-Environmental Schemes adoption; 5) Improve the effectiveness of future EU rural policies’ design, monitoring and implementation.

ECONOMIC VALUATION OF ECOSYSTEM SERVICES: A CASE STUDY FOR SUSTAINABLE MANAGEMENT OF DEGRADED PEATLANDS IN LATVIA

Ecosystem services (ES) are the benefits that people obtain from using ecosystems and can be divided into the following three categories: provisioning, regulating and supporting and cultural services. The strategical importance of ecosystem services is set by the EU Biodiversity Strategy, which put ecosystem services firmly on the EU policy agenda. The aim of the paper is to present and discuss the model for economic (monetary) valuation of ecosystem services for sustainable management of degraded peatlands in Latvia. Based on an economic valuation of ecosystem services (ES), it is possible to compare different territories and different management scenarios. Peatland ecosystems globally represent a major store of soil carbon, a sink for carbon dioxide and a source of atmospheric methane. Climate change may threaten these stocks due to the peat oxidation caused by the draught in areas where the peat extraction has been carried out, as well as the increased risk of forest fires. In Latvia, currently there have not been developed a strategy for the implementation of standard approaches and basic principles for the management of degraded peatlands. There are several options for re-cultivation of degraded peatlands, but for sustainable land use, it is very important to choose the most optimal option from the economic, ecological and society perspective. The research was based on data obtained from a biophysical ES assessment for 28 indicators for 3 scenarios from a 5, 25 and 50-year perspective. The collection of primary data, as well as an aggregation and comparative assessment of secondary data have been carried out by using approbated scientific research methods and ES assessment indicators. The obtained data were adapted to the Latvian socio-economic situation by using correction factors. Depending on ES category, the following assessment methods were used: the market pricing method; the benefit transfer method and the direct market pricing method; the avoided costs method. Economic valuation of peatland re-cultivation scenarios assists land-use planners and policymakers in making ecologically, economically and socio-culturally sustainable land-use decisions, where ecological and economic data are used for a calculated assessment of the land-use options.

Integrating supply and demand in ecosystem service bundles characterization across Mediterranean transformed landscapes

Humans continually transform landscapes, affecting the ecosystem services (ES) they provide. Thus, the spatial relationships among services vary across landscapes. Managers and decision makers have access to a variety of tools for mapping landscapes and analyzing their capacity to provide multiple ES. This paper characterizes and maps ES bundles across transformed landscapes in southeast Spain incorporating both the ecological and social perspectives. Our specific goals were to: (1) quantify ES biophysical supply, (2) identify public awareness, (3) map ES bundles, and (4) characterize types of ES bundles based on their social-ecological dimensions. Biophysical models and face-to-face social surveys were used to quantify and map ES bundles and explore the public awareness in a highly transformed Mediterranean region. Then, we classified ES bundles into four types using a matrix crossing the degree of biophysical ES supply and the degree of social awareness. Results mapped seven ES bundles types representing diverse social-ecological dynamics. ES bundles mapped at the municipality level showed mismatches between their biophysical provision and the public awareness, which has important implications for operationalizing the bundles concept for landscape planning and management. ES bundles characterization identified four types of bundles scenarios. We propose an ES bundles classification that incorporates both their social and ecological dimensions. Our findings can be used by land managers to identify areas in which ES are declining as well as priority areas for maximizing ES provision and can help to identify conflicts associated with new management and planning practices.

From instantaneous to continuous: Using imaging spectroscopy and in situ data to map two productivity-related ecosystem services

Spatially well-informed decisions are essential to sustain and regulate processes and ecosystem services (ES), and to maintain the capacity of ecosystems to supply services. However, spatially explicit ES information is often lacking in decision-making, or exists only as ES maps based on categorical land cover data. Remote sensing (RS) opens new pathways to map ES, in particular biophysical ES supply. We developed an observation-based concept for spatially explicit and continuous ES mapping at landscape scale following the biophysical part of the ES cascade. We used Earth observations in combination with in situ data to map ecosystem properties, functions, and biophysical ES supply. We applied this concept in a case study to map two ES: carbon dioxide regulation and food supply. Based on Earth observations and in situ data, we determined the ecosystem property Sun-Induced chlorophyll Fluorescence (SIF) to indicate ecosystem state and applied scaling models to estimate gross primary production (GPP) as indicator for ecosystem functioning and consequently carbon dioxide regulation and food supply as ES.Resulting ES maps showed heterogeneous patterns in ES supply within and among ecosystems, which were particularly evident within forests and grasslands. All investigated land cover classes were sources of CO2, with averages ranging from ‐66 to ‐748g C m‐2 yr‐1, after considering the harvest of total above ground biomass of crops and the storage organ, except for forest being a sink of CO2 with an average of 105g C m‐2 yr‐1. Estimated annual GPP was related to food supply with a maize grain yield average of 9.5t ha‐1 yr‐1 and a sugar beet root yield of 110t ha‐1 yr‐1. Validation with in situ measurements from flux towers and literature values revealed a good performance of our approach for food supply (relative RMSE of less than 23%), but also some over- and underestimations for carbon dioxide regulation. Our approach demonstrated how RS can contribute to spatially explicit and continuous ES cascade mapping and suggest that this information could be useful for environmental assessments and decision-making in spatial planning and conservation.

The Integration of Ecosystem Services in Planning: An Evaluation of the Nutrient Retention Model Using InVEST Software

Mapping ecosystem services (ES) increases the awareness of natural capital value, leading to building sustainability into decision-making processes. Recently, many techniques to assess the value of ES delivered by different scenarios of land use/land cover (LULC) are available, thus becoming important practices in mapping to support the land use planning process. The spatial analysis of the biophysical ES distribution allows a better comprehension of the environmental and social implications of planning, especially when ES concerns the management of risk (e.g., erosion, pollution). This paper investigates the nutrient retention model of InVEST software through its spatial distribution and its quantitative value. The model was analyzed by testing its response to changes in input parameters: (1) the digital terrain elevation model (DEM); and (2) different LULC attribute configurations. The paper increases the level of attention to specific ES models that use water runoff as a proxy of nutrient delivery. It shows that the spatial distribution of biophysical values is highly influenced by many factors, among which the characteristics of the DEM and its interaction with LULC are included. The results seem to confirm that the biophysical value of ES is still affected by a high degree of uncertainty and encourage an expert field campaign as the only solution to use ES mapping for a regulative land use framework.

Revealed social preference for ecosystem services using the eco-price

Ecosystem services have predominately been valued from the perspective of individual preference, where the willingness to pay of an individual is measured either directly or indirectly. However, when one observes where money is spent on increasing ecosystem services, preserving them, compensating for their loss, or replacing lost services it is almost always through collective action of governments, corporations, or non-governmental organizations. This work suggests that revealed social preference is the most appropriate economic perspective for institutions to use in analyzing the value of ecosystem services, particularly when the scale of inference is large, the decisions to be made are multiple, or the final use of the ecosystem service is uncertain. The eco-price collates instances where society has paid for an increase in ecosystem services, to avoid their loss or restore damages, in the form of $ paid per biophysical unit of ecosystem service. Eco-prices are categorized by type of biophysical work done (i.e. water, carbon, nutrients, soil, and biodiversity). Applying the categorical eco-prices to biophysical ecosystem services flows for average forest and freshwater wetland conditions in Maryland yields an estimate of the annual ecosystem service benefit of $5,767 per hectare of forest and $9,693 per hectare of freshwater wetlands.

Ecosystem services assessment and compensation costs for installing seaweed farms

In a global context of promotion and expansion of blue growth initiatives, the development of activities such as aquaculture calls for the assessment of the potential impacts on biodiversity at different levels and associated services. This paper presents an assessment of the potential impact of the installation of seaweed farms on ecosystem services and the induced compensation costs. Biophysical and socioeconomic indicators have been developed for helping decision makers to select the most suitable locations. The approach considers a multi-criteria approach based on Geographical Information Systems (GIS) and Habitat Equivalency Analysis (HEA). The former is used to obtain biophysical ecosystem services and socioeconomic indicators and the latter to evaluate the costs required to compensate the loss of cultural and provisioning ecosystem services. A case-study in the Normand-Breton (Saint Malo) Gulf, France, illustrates this method through the analysis of hypothetical locations of seaweed farms. Results highlight the differences between alternative locations regarding biophysical constraints (in terms of distance and depth), potential risks of conflicts with existing uses, impacts on habitats and the ecosystem services delivered, and compensation costs. This case-study illustrates the flexibility of this approach which can be further adapted to include other indicators in order to deliver integrated information to coastal planners.

Allotment gardens and parks: Provision of ecosystem services with an emphasis on biodiversity

Urban areas, in particular, present unique challenges for the conservation of ecosystems. Allotment gardens (AGs) are an important greenspace feature of urban landscapes in Europe which have the potential to offer multiple social and bio-physical ecosystem services in addition to food production. This study is an attempt to assess and compare the ecosystem services provided by AGs in Manchester, UK, and Poznań, Poland as well as a comparison to city parks. The surveys included a detailed land cover characterisation and an assessment of cultivated and spontaneous plant species. There are differences in the land use characteristics in the two cities with a preference for vegetable growing and water recycling in Manchester, and a greater number of trees and a higher focus on recreation in Poznań. The consequences of these basic differences are discussed in terms of the ecosystem services that are provided by the two different AG types, and parks. In terms of ecology, there is higher species richness on AGs with a greater proportion of neophytes, which may potentially spread into cities. The species recorded in parks and AGs contained a lot of native characteristics of urban, ruderal plant communities.
