The ecosystem services framework is receiving increasing attention in the fields of policy and research. The assessment of human attitudes and perceptions regarding ecosystem services has been proposed as a promising tool for addressing complex problems associated with environmental change, particularly in the context of cultural landscapes. Transhumance is not only a farming practice responsible for shaping cultural landscapes but also an adaptive strategy based on mobility that may represent a useful approach to overcoming the growing challenges posed by accelerated environmental change. A socio-cultural valuation of ecosystem services associated with the Conquense Drove Road, one of the major transhumant networks still in use in Mediterranean Spain, was conducted via the distribution of questionnaires to 416 local residents and visitors to capture their perceptions regarding the importance of 34 ecosystem services (10 provisioning, 12 regulating, and 12 cultural) for both social and personal well-being. Overall, the ecosystem services considered to be the most important for social well-being were fire prevention, air purification and livestock. Most of the ecosystem services in question were perceived as declining, with the exception of those associated with recreation, scientific knowledge and environmental education. This study revealed that perceptions regarding the value of ecosystem services differed among respondents, depending on their age, place of origin and gender. Several methodological issues, as well as the implications of socio-cultural valuation for policy making, are also discussed here.  相似文献

Through extensive research, ecosystem services have been mapped using both survey-based and biophysical approaches, but comparative mapping of public values and those quantified using models has been lacking. In this paper, we mapped hot and cold spots for perceived and modeled ecosystem services by synthesizing results from a social-values mapping study of residents living near the Pike–San Isabel National Forest (PSI), located in the Southern Rocky Mountains, with corresponding biophysically modeled ecosystem services. Social-value maps for the PSI were developed using the Social Values for Ecosystem Services tool, providing statistically modeled continuous value surfaces for 12 value types, including aesthetic, biodiversity, and life-sustaining values. Biophysically modeled maps of carbon sequestration and storage, scenic viewsheds, sediment regulation, and water yield were generated using the Artificial Intelligence for Ecosystem Services tool. Hotspots for both perceived and modeled services were disproportionately located within the PSI’s wilderness areas. Additionally, we used regression analysis to evaluate spatial relationships between perceived biodiversity and cultural ecosystem services and corresponding biophysical model outputs. Our goal was to determine whether publicly valued locations for aesthetic, biodiversity, and life-sustaining values relate meaningfully to results from corresponding biophysical ecosystem service models. We found weak relationships between perceived and biophysically modeled services, indicating that public perception of ecosystem service provisioning regions is limited. We believe that biophysical and social approaches to ecosystem service mapping can serve as methodological complements that can advance ecosystem services-based resource management, benefitting resource managers by showing potential locations of synergy or conflict between areas supplying ecosystem services and those valued by the public.  相似文献

The notion of ecosystem services is considered useful for integrating perceptions and values into decision-making on environment and nature. Sociocultural factors have been suggested to explain perceptions and values assigned to ecosystem services. We examine this by undertaking a sociocultural valuation of ecosystem services provided by the natural park of Sant Llorenç del Munt, located at the edge of the Barcelona Metropolitan Region. Four methods are used, namely a review of the literature on ecosystem services, non-participant observation, semi-structured interviews with stakeholders and a valuation survey among visitors. We assess whether visitors and other stakeholders understand the term ecosystem service, finding that the concept is rather unknown or misunderstood. Among the 28 ecosystem services identified, habitat and cultural services were the most valued. We statistically identify socioeconomic characteristics of visitors that have a main influence on their valuation of ecosystem services. We further assess diverging preferences of all stakeholders that might give rise to conflicting views about policies for protected areas. We draw lessons about the usefulness of the multi-method approach and about the management of protected areas.  相似文献

The importance of forest resources for rural communities’ livelihoods has increasingly been recognized over the last three decades. Forests provide food, generate incomes, provide supporting (nutrient cycling, pollination), and regulating (climate, diseases, water regulation and purification) services for agriculture, in addition to their aesthetic, cultural and spiritual role. However, most of the studies on forest resource use do not focus on the role of landscape organization in addressing the impact of climate variability and the risk of food insecurity. This study aims to examine the contribution of woodlands and trees towards decreasing the risk of food insecurity and the importance of landscape structure and composition in coping with food shortages. It took place in two villages in Burkina Faso, on both ends of the woodlands and tree-cover spectrum. We demonstrate that in both landscapes, ecosystem goods, such as shea nuts and fuelwood, represent a safety net for households during food shortage periods. We demonstrate that households shape their adaptive strategies differently depending on the resources available and the structure of the landscape. People living in a landscape with a savannah matrix (Sorobouly) rely on fuelwood trade to purchase cereals, while those living in a landscape with a parkland matrix (Kalembouly) rely on shea nuts. Agricultural, environmental and climate change policies that reinforce the rights of the most vulnerable to access key resources provided by these landscapes and development programs which assure their sustainable use will simultaneously enhance food security and increase their adaptive capacity in the face of climate change and variability.

Farming communities are increasingly expected to manage their agricultural activities in ways that ensure sustainable flows of a wide range of ecosystem services for society. The land use and management choices that farmers make are dependent upon their socio-economic characteristics and background, and in turn have important implications for the landscape and associated ecosystem services. Thus, a better understanding about the linkages between the characteristics of farmers, farm management and land use is important for managing multifunctional agro-ecosystems. In this paper, we first develop a typology of farmers for Torrealvilla catchment in Murcia, Spain, according to the characteristics of their households and farm management (e.g. the farmer’s age, household income, water access, land tenure and farm labour). This analysis distinguishes six types of farmers. Secondly, we analyse the link between farmer typology and the farmers’ responses to a number of scenarios. The scenarios describe different likely changes to agriculture in the catchment in terms of environmental constraints (irrigation water availability and rainfall pattern) and environmental policy regulation (water taxation and subsidies). This exercise enables us to explore the range of future land use changes that are likely to occur in the study area. The results indicate that: rain-fed agriculture is expected to experience gradual but extensive abandonment; vegetable/fruit farming and pig/animal rearing are likely to stagnate or even decline; and growing of grapes is likely to expand. Thirdly, we qualitatively evaluate how future land use changes are likely to affect key ecosystem services in the study area including future agricultural production and associated local income generation, erosion control, maintenance of the groundwater table and various cultural services associated with a heterogeneous agro-ecosystem. Particular changes such as expansion of grape production will increase food production and local income at the cost of further depletion of the aquifer and increased risk of salinisation. The outcomes of the study highlight that, to be effective, the design of agri-environmental schemes and other government interventions (e.g. specific compulsory regulations on farming practices and associated water use) should carefully take into account the characteristics of the farmers within the area of interest, their land uses and the possible diversity of responses to policy and environmental drivers. Opportunities exist for future studies quantifying the extent of the impacts of ecosystem service provision through formal models combining farmers’ land use decision-making and spatially explicit modelling of landscape processes.  相似文献

Many regulating ecosystem services exhibit non-excludability and non-rivalry characteristics akin to public goods. This makes it unlikely that such regulating ecosystem services will attract a price in the marketplace. Policymakers, therefore, find difficulties in determining a correct economic valuation for regulating ecosystem services, with potentially severe consequences for aligning policy for ecosystem service provision with public preferences for service delivery. This research used a choice modelling approach to estimate public preferences for delivery of two regulating ecosystem services; reductions in the flood risk to the British city of York (implemented by filling in drainage ditches in peat moorland further up the catchment), and a reduction in CO2 emissions (implemented by planting Poplar trees for biomass either locally in the study area or elsewhere in the UK). The choice experiment presented respondents with options providing different levels of CO2 reduction, implemented locally or nationally, and different levels of flood risk reduction, at a range of different prices, with a tax as the payment vehicle. Subsequent analysis with latent class (LC) models showed considerable heterogeneity of preference among respondents, particularly with regard to the location of tree planting for CO2 reduction. One LC segment showed a significant preference for achieving a high level CO2 reduction through national, as opposed to local tree planting, potentially indicating the existence of NIMBYism. The same LC segment displayed a preference for moderate reductions in the flood risk to York, even though this would deliver no personal benefit for a substantial proportion of the segment. This could, therefore, indicate altruistic behaviour towards geographically proximate beneficiaries.  相似文献

城市绿地生态功能综合评价体系研究的新视角   总被引:2,自引:0,他引:2  
在对城市绿地生态系统评价研究中人们关注的焦点主要集中在城市绿地为人类提供的生态服务功能,而忽视绿地自身运转功能。构建科学、完善的城市绿地生态系统功能综合评价体系,对于重新认识城市绿地生态系统的综合功能,提升绿地建设和管理水平具有重要的意义。本文分析了目前城市绿地生态系统功能评价容易忽略的绿地数量和面积与生态功能的关系、人工绿地生态系统与自然生态系统生态功能的差异、对城市绿地特殊生存环境和后期科学管护的忽视、只重视城市绿地功能和价值而忽视建设和管护成本以及绿地建设的内涵在城市园林绿化中被曲解等几个问题,在此基础上从绿地生存环境优良性、绿地健康状况、绿地综合效益评价、居民对绿地感知认识出发,探索并构建城市绿地生态系统功能综合评价体系,以反映城市绿地与城市环境之间的适应性和绿地是否能有能力提供足够的生态服务以及居民对绿地生态效益、景观效益、社会经济效益的感知和认同,旨在为城市绿地规划、建设和管护提供有力支撑和指导,更好发挥城市绿地生态系统综合效益。  相似文献

The aim of this study was to identify and evaluate major terrestrial- and marine species-based provisioning ecosystem services (PESs) provided by the socio-ecological production landscapes and seascapes (SEPLS) of Lefke Region located in North Cyprus. The objectives of the study include: (1) identifying major terrestrial-based PESs collected from the SEPLS (e.g. wild plants) and (2) recording major marine-based PESs caught (e.g. fish species), and (3) proposing several policy responses based on the results of (1) and (2) and on a review of the literature and current policies. The method of the study consists of two parts. Primarily, a conceptual framework for understanding the linkages among the SEPLS, PESs and landscape planning in Lefke Region was developed. Secondly, a participatory research approach was implemented to identify major PESs gathered from the SEPLS in the region. A range of data collection tools (e.g. a questionnaire and semi-structured interviews) were used to collect data on the research questions in 12 villages from December 2015 to March 2016. The precise data on the PESs were obtained from 106 participants that responded to the questionnaire. Assessment of the questionnaire showed that the local people collect various terrestrial (49 plant and 5 mushroom species)- and marine (30 fish species)-based PESs from the SEPLS for a variety of purposes (e.g. private own use, income generation and nature experience). Finally, potential policy responses for better conservation and sustainable management of the PESs and the SEPLS (e.g. development of a national landscape planning strategy for North Cyprus and integration of the concept of ecosystem services) of the region were examined. It is expected that the results of this study can draw attention of policy-makers, planners and natural resource managers to better understand the feedbacks between SEPLS and associated ecosystem services in terms of biodiversity conservation, food production and sustainable livelihood development in Lefke Region and elsewhere.  相似文献

ABSTRACT

Urban planning has become a widely concern for minimizing the negative effects of urban expansion on terrestrial ecosystems. We developed an interdisciplinary modeling framework to evaluate the effectiveness and shortcomings of urban expansion management strategies. A three-step method was applied to Yinchuan Plain in the northwestern of China, including (1) analyzing the relationship between landscape pattern and ecosystem service values through mathematical statistics; (2) predicting landscape pattern and ecosystem services change under different scenarios based on cellular automaton model (SLEUTH-3r model); and (3) designing and validating optimized scenario through integrating historical analysis experiments and future multi-comparison suggestions. Results have suggested that landscape composition and configuration can significantly affect regional ecosystem service values, especially the connectivity and shape of landscape. Compact urban growth policy and medium environment protection policy are the appropriate setting for urban expansion plan. Optimization validation of the combined designed scenario implied the reliability of this method. Our results highlighted the significance of integrating application of landscape pattern analysis, ecosystem service value evaluation, model simulation and multi-scenario prediction in urban planning.  相似文献

As part of a larger study to quantify and map ecosystem services in southeast Australia, we estimated carbon stored in biomass and soils and the net ecosystem carbon exchange between the land surface and the atmosphere in the Australian Capital Region (ACR). Our aim was to understand and quantify how different human-modified landscapes provide an essential ecosystem service: the exchange and storage of carbon in the landscape. Using a remote sensing based modelling methodology, we obtained values of Net Primary Productivity (NPP), total carbon in soil and biomass and carbon turnover from meteorological and terrain inputs and vegetation attributes. We obtained a set of maps of NPP, total carbon (C) storage and C-turnover for the ACR. We superimposed a land use/cover map to assign the uptake, storage and release of carbon to different land use/cover types. Our results support the hypothesis that human-intensive land uses significantly affect the ability of terrestrial ecosystems to provide an important ecosystem service in the form of carbon storage.  相似文献

Despite the importance of neotropical cloud forests as providers of ecosystem services to society, they are one of the most threatened ecosystems in the world. We analysed the importance of three cloud forest reserves in central Colombia as providers of ecosystem services, as well as the social support to conservation actions in these ecosystems through willingness to pay (WTP) and willingness to give up time (WTT) estimates. Our results highlight the high commitment of all users of the cloud forest areas towards the conservation of the ecosystem services provided by these strategic ecosystems. We found that the most important perceived ecosystem services were water supply and habitat maintenance for species. Our findings also suggest that the respondents’ ecological knowledge (measured as the awareness of the ecosystem services supplied by cloud forests) was an important factor in determining both WTP and WTT for conserving cloud forests. Moreover, our results indicate that WTT should be a viable technique to explore individual preferences of different stakeholders towards conservation activities in cloud forests. Based on our results, we propose a conservation strategy of cloud forests that considers different users’ socio-economic and environmental characteristics, in which both experimental and experiential knowledge should be incorporated in order to promote collective action.  相似文献

Facing the challenges of global and regional changes, society urgently needs applicable and broadly accepted tools to effectively manage and protect ecosystem services (ES). This requires knowing which ES are perceived as important. We asked decision-makers from different thematic backgrounds to rank 25 ES on the basis of their importance for society. To test whether perceptions are varying across regions, we surveyed three Alpine regions in Austria and Italy. The ranking of importance showed a high variability amongst experts but was not influenced by region or thematic background. ES that satisfy physiological needs (‘fresh water’, ‘food’, ‘air quality regulation’) were indicated as most important. ES that relate to safety and security needs were ranked in the middle field, whereas cultural ES were perceived as less important. We used principal component analysis (PCA) to identify ES bundles based on perception of importance. In order to investigate whether research intensity follows the perceived importance, we related the interviews with a comprehensive literature review. ‘Global climate regulation’, ‘food’, ‘biodiversity’, ‘fresh water’ and ‘water quality’ were studied most often. Although ‘habitat’, ‘energy’, ‘primary production’, ‘tourism’, ‘water cycle’, and ‘local climate regulation’ were ranked as important by decision-makers, they did not receive corresponding research attention. We conclude that more interaction between research and stakeholders is needed to promote a broader application and understanding of the ES concept in practice. The use of ES bundles could help to manage its inherent complexity and facilitate its application.  相似文献

New approaches have emerged in integrating ecosystem services, their structure and function for ecological restoration. As the concept relating with ecosystem services has become widely accepted in last decade in China, its linking with ecological restoration will provide good opportunities and make substantial progress towards sustainable development. By analyzing the traditional ecological restoration procedure in China, we developed a framework of ecological restoration based on ecosystem services valuation. Relevant researches of ecological restoration based on ecosystem services are also carefully reviewed. China’s ecosystem services studies and payments for ecosystem services (PES) experiences were extensively discussed to show the ecological restoration strategy and its change. Two case studies in China were presented to show the framework for ecological restoration based on PES. We suggested that despite the limitations of valuation uncertainties at present, PES could be an opportunity for ecological restoration by evaluating the trade-offs of different stakeholders. In current state in China, challenges and opportunities coexist and scientists should work together in the integrated research of sustainable ecological management and economic development policies.  相似文献

Abstract

Miyun County, located in the northeast of Chinese capital Beijing, was underwent remarkable variations in land use in recent years. This paper aimed to detect changes in land use of Miyun from 1997 to 2005, and to qualify the response of ecosystem to LUCC based on ecosystem services valuation. With two-periods TM images, we got land use change data, and then ecosystem services values were calculated using ecosystem services valuation coefficients proposed by Chinese scholar Xie Gaodi. Results showed that water area, farm land and unused land decreased while residential land, forest land, grassland and orchard land increased during the study period. The loss of ESV was RMB 206 million and the main reason was the decrease of water area and farm land area. As for spatial variation, there were most dramatically land use change and ESV decline in reservoir ecological protection region. The coefficient sensitivity analysis indicates that valuation coefficients used in the study are suitable and results are reasonable. The driving forces of ESV loss were rapid population growth and economic development. More work should be done to make eco-environment stay healthy.  相似文献
