This research develops the novel concept of an economic ecosystem service sustainability index from the perspective of total income theory, and presents its empirical application at the spatial unit scale of the agroforestry farm. This paper compares the results accrued from applying the refined standard System of National Accounts (rSNA) and the authors’ Agroforestry Accounting System (AAS). The AAS extends the rSNA to capture economic activities without manufactured production costs and substitutes the production cost valuations for exchange values revealed/stated by consumer willingness to pay for consumption of final products without market prices, the aim being to provide more comprehensive figures for total and environmental incomes of the agroforestry farms. Both accounting frameworks are applied to a case study of sixteen large, non-industrial, privately-owned holm oak dehesas (agroforestry farms) in Andalusia-Spain. This dehesa application provides estimates for the economic ecosystem service, total income factorial allocation, total capital and economic ecosystem service sustainability index for the aggregate and individual economic activities of the dehesa, distributed between accounts for the farmer and government institutional sector economic activities. The AAS explicit measurements of the hidden rSNA ecosystem services and environmental incomes of the dehesa allow us to further our scientific understanding of the current and future contributions of environmental income from nature to the total income of society as well as to provide information to the policy makers so that action can be taken to mitigate the depletion and degradation of environmental assets. This dehesa application reveals that environmental income measured by the AAS accounts for 67 % of total income in 2010. The dehesa AAS and rSNA ecosystem services share 34 % and 26 % of total product consumptions, respectively. Coupled with the AAS economic ecosystem service sustainability index of 0.5 and the rSNA economic ecosystem service sustainability index of 0.2, these figures indicate total product over-consumption in 2010. The dehesa case study shows that the AAS ecosystem services and environmental incomes are 2.5 and 8.4 times higher than those of the rSNA, respectively. Once the theoretic robustness of non-market product consumption simulated transaction value is accepted, as in the AAS methodology, the expected official economic ecosystem accounting framework will mainly depend on its ongoing standardization by the United Nations Statistical Division and implementation by individual governments. Thus, the challenge of standardizing and implementing such a framework is more closely linked to governmental policy measures than to the current scientific weakness of non-market product consumption valuations.  相似文献

We explore the evolutionary nature of interactions between government policy, farm decision-making and ecosystem services in Shucheng County, Anhui Province, 1950–2015. Analyses of ecological, social and economic trends are complemented by interviews with local farmers. Since the Household Responsibility System started in 1980, there has been a trade-off between rising levels of provisioning services and falling levels of regulating services with evidence that critical thresholds have been passed for water quality. Using a Framework for Ecosystem Service Provision, we argue that farmers have acted only as ecosystem service providers and have not influenced the policies that have brought about the trade-offs. Over the period, ecological degradation is best described as an example of ‘creeping normalcy’ where cumulative conventional actions by individual farmers produce unsustainable losses in regulating services. The Chinese government should act to balance the various ecosystem services through valuation and national policy. In this respect, there is a need for agencies that can provide place-based advice to farmers that will allow them to maintain productivity levels while pursuing restorative actions. Even with new policies, the draw of urban employment, high production costs and an ageing population threaten the viability of farming in these marginal agricultural areas.  相似文献

Understanding the co-occurrence of multiple ecosystem services within farming systems and how they are associated across space are relatively new topics. Quantifying ecosystem services and their interactions as dependent on cropland management can help to formulate a more effective and sustainable land use management system. However, current academic efforts and cropland management practices based on the perspective of ecosystem services bundles and tradeoffs remain limited, especially in developing countries. This paper aimed to integrate ecosystem services into cropland protection and functional zoning. Taking Cixi County in the Hangzhou Bay area, China, as the case study area, five typical ecosystem services (food supply, carbon sequestration, hydrological regulation, soil fertility and recreation potential) delivered by croplands and their correlations were quantitatively assessed. The results demonstrated a heterogeneous spatial pattern of multiple ecosystem services and diverse interactions between them, which depended on regional specific conditions and agricultural activities. Further, we adopted the framework of ecosystem services bundles as a planning tool to support the spatial strategy of cropland management. Cropland protection priority and functional zoning were determined by hotspot analysis and clustering algorithms, respectively. The croplands in Cixi were classified into three protection grades and a zoning scheme comprising four functional types with policy guidelines was proposed based on the spatial cluster results. The integrative approach used in this study is applicable to supplement the current cropland management actions by incorporating the perspective of ecosystem services tradeoff and bundles.  相似文献

Estimation of ecosystem service values is a hot area of research in ecological conservation and economics. However, the costs of these outputs are largely unknown. In this paper, we estimated the opportunity cost of water allocated to afforestation projects through mathematical modeling based on statistical data for all of China to provide support for restoration planning based on a fuller consideration of the true costs. To guide future ecological conservation and environmental policy development, we illustrate a neglected concept (ecosystem service costs) and use this concept to compare the ecological services provided by ecological restoration based on afforestation with those of restoration based on the conservation of natural vegetation using data obtained since 1949 in China. The results showed that afforestation and natural vegetation create annual costs related to use of the available water resources equal to 4800 and 3700 RMB ha−1, respectively, representing a water opportunity cost of 1100 RMB ha−1 for afforestation. This illustrates the rule that “there is no free lunch” for any service, including ecosystem services. Therefore, to support the development of more effective and sustainable environmental restoration policy, it will be necessary to evaluate the associated opportunity costs.  相似文献

The standard System of National Accounts (SNA) omits the costs of the environmental inputs from nature and the environmental fixed asset degradation from the national/sub-national natural working landscapes. The United Nations Statistic Division (UNSD) is currently drafting the standardization of the Experimental Ecosystem Accounting (EEA), as part of the System of Environmental-Economic Accounting (SEEA). The EEA- aims to mitigate some of the limitations of the SNA by extending the concept of economic activity and explicitly incorporating ecosystem services and environmental assets provided by nature in the estimates of net value added, adjusted according to the costs of the environmental inputs consumed and the environmental fixed asset degradations of ecosystem. However, the NVAad proposed in the ongoing draft of the EEA is inconsistent in that it omits the manufactured costs of the public economic activities of the new government institutional sub-sector of the ecosystem trustee. In addition, the ongoing methodological guidelines of the EEA do not propose to estimate the environmental income. This implies that there is not a single indicator that integrates the ecosystem services obtained and the evolution of the environmental assets in the natural working landscapes in which the private and public activities are valued. The objective of this research is to discuss conceptually and compare the measurements of ecosystem services and environmental incomes in the extended Agroforestry Accounting System (AAS), and in refined versions of the official SNA and the ongoing EEA methodologies, through a case study of privately-owned holm oak dehesas working landscapes in Andalusia-Spain. This comparison shows that the refined SNA and the refined EEA in their current state of development do not allow the complete visualization of the environmental income contribution to the total income of the natural working landscapes. We also discuss the advances provided by the AAS extended accounting methodology that would be relevant for the EEA next improvements.  相似文献

Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible.  相似文献

A series of approaches have been proposed for natural resource management and biodiversity conservation in recent decades. In the important forestry sector, two of the most dominant policy paradigms have been multi-purpose forestry and sustainable forest management. The Convention on Biological Diversity, amongst other transnational commitments, added the ecosystem approach and its related idea of ecosystem services to this succession which is increasingly becoming the basis for natural resource management, including in the United Kingdom (UK). However, this latest addition raises the stimulating question of whether in forestry the ecosystem approach and the associated ecosystem services concept really constitute something fundamentally new, or are merely an extension or re-branding of existing policy approaches. This paper contributes to a lively contemporary debate surrounding the ecosystem approach and ecosystem services, by examining how these two interrelated but distinctly different concepts are currently understood and adopted within UK forestry and in the context of established forestry policy paradigms. For this purpose, I undertook a review of the scholarly literature and legal and policy documents which have been triangulated with a survey of the attitudes, interpretations and opinions of forestry stakeholders through expert interviews. The analysis suggests that in the UK forestry sector, as elsewhere, the frequency of, often broad and ambiguous approaches to natural resource management and biodiversity conservation in general, and forestry policy and management in particular, are causing confusion amongst some stakeholders, who, unsurprisingly frequently conflate concepts seemingly without understanding the details. However, a clear understanding of the differences and similarities of these important concepts, stemming from overlapping but different disciplines, is crucially important for successful policy implementation and sustainable forest management. This article attempts to contribute to such a clarification and to further interdisciplinary understanding.  相似文献

The ecosystem services (ES) framework reveals ecosystems’ benefits to society and presents a fundamental natural resource management approach. In the last several decades, it has gained increasing attention from the research community, and it recently reached the political agenda. However, does the concept have the capacity to cause institutional change in environmental policy? To answer this question, we developed certain criteria for an “ideal” ES-driven policy. Based on these criteria, we analyzed the main water and biodiversity acts, current policy developments, and future trends within the US and the EU. Our analysis shows that most acts cannot be explicitly characterized as ES-driven policies, but parts of the concept are already included. The ES framework, increasingly a driver in several policy fields, can be assumed to be a major future influence for shaping existing environmental policies in the coming decades. We discussed the results based on its strengths for existing environmental policy conceptually, e.g., cross-sector cooperation and ES win-win and trade-off considerations, and its weaknesses operationally, such as measurability and governance changes.  相似文献

We argue that to support agriculture–environmental policy decision making, stakeholders need ‘quantitative back‐of‐the‐envelope’ analysis that is timely and sufficiently accurate to make informed decisions. We apply this concept to the analysis of the supply of ecosystem services from agriculture. We present a spatially explicit production model and show how it can be used to derive the supply of ecosystem services in a region. This model shows that the supply of ecosystem services can be derived from the spatial distribution of opportunity cost of providing those services. We then show how this conceptual model can be used to develop a minimum‐data (MD) approach to the analysis of the supply of ecosystem services from agriculture that can be implemented with the kinds of secondary data that are available in most parts of the world. We apply the MD approach to simulate the supply of carbon that could be sequestered in agricultural soils in the dryland grain‐producing region of Montana. We find that the supply curve derived from the MD approach can approximate the supply curve obtained from a more elaborate model based on site‐specific data, and can do so with sufficient accuracy for policy analysis.  相似文献

Urban regions are important places of ecosystem service demands and, at the same time, are the primary source of global environmental impacts. Although there is broad agreement on the importance of incorporating the concept of ecosystem services into policy strategies and decision-making, the lack of a standardized approach to quantifying ecosystem services at the landscape scale has hindered progress in this direction. Moreover, tradeoffs between ecosystem services and the supply/demand ratio of ecosystem services in urban landscapes have rarely been investigated. In our paper, we present a method to quantify and map the supply and demand of three essential provisioning services - energy, food, and water - along the rural-urban gradient of the eastern German region Leipzig-Halle. This urban region has experienced significant socio-economic dynamics and land use changes since the German reunification in 1990. The results show that both the demand and the supply of ecosystem services changed considerably during the time span under consideration (1990-2007). We identified an increasing supply/demand ratio of food and water but a decreasing supply/demand ratio of energy. In addition, the pattern of ecosystem demands shows a levelling of rural-urban gradients, reflecting profound modifications of traditional rural-urban relationships. The changes of ecosystem service supply gradients are determined more by land use intensity, such as the intensification of agricultural production, than by land cover changes such as urban sprawl. The comparison of supply/demand ratios and rural-urban patterns of ecosystem services can help decision-makers in landscape management in striving for a sustainable balance between resource supply and demand.  相似文献

The Governance of Rural Land in a Liberalised World   总被引:1,自引:0,他引:1  
Liberalisation of agricultural policies reduces the influence of policy on land‐use decisions, but environmental policy objectives remain. Governance provides an approach that recognises the role of institutions and collective action. The formulation of environmental policy objectives in terms of the provision of public goods raises questions as to the role of economic valuation and as to whether the definition of ‘goods’ may misdirect policy attention. An alternative approach relates to ecosystem services and sees management issues in terms of ecosystem resilience and the adaptive governance of socio‐ecological systems. Governance involves a mix of regulation, markets, government incentives and collective action. Regulation sets the domain within which markets operate and social judgements as to property rights are required as a basis for exchanges. Depending on commodity prices, agri‐environment schemes may be required either to reduce agricultural production intensity or to keep land under production. The diffuse nature of the environmental benefits and costs of land uses, the complexity of ecosystems and the need to co‐ordinate land management decisions indicate a role for local adaptive co‐management of land resources. Governments play a major role in supporting the institutional framework within which this can take place.  相似文献

Targeting of agri-environmental measures (AEMs) is a key to increasing the cost-effectiveness of governmental support for biodiversity conservation and the provision of ecosystem services from agriculture. Existing literature, however, often focuses on single measures without considering that policies are usually bundles of different measures addressing multiple non-marketed goods and services. Thus, interaction effects of a set of policies in a given policy mix may influence the cost-effectiveness of single measures. Recently, Swiss agricultural policy was redesigned using the Tinbergen rule as its basis, i.e., a single measure for each policy goal, including additional targeted direct payments. This facilitates testing for interaction effects of multiple targeted AEMs. Here we use a social-ecological, agent-based modelling framework to assess interaction effects of these agricultural policies while accounting for climate change impacts in our analysis. The results from our case study in a mountain region show that ecosystem service provision increases with targeted payments. However, interaction effects of the different targeted policies affect the provision levels of all goods and services. In particular, changes at the extensive margin, i.e., the total amount of land that is under production, largely determine the amount of ecosystem services provided. Thus, climate change driven productivity increases and policies that keep land in production may substantially support the provision of non-marketed goods and services in marginal agricultural production regions with a high potential for land abandonment. Consequently, the effectiveness of targeted policy measures should also consider changes at the extensive margin and be assessed in the context of bundles or portfolios of different policy measures.  相似文献

The ecosystem services concept is increasingly considered as a policy tool to achieve the sustainable use of natural resources. However, it is still not sufficiently integrated into land use planning. We assessed five land use types (Tetraclinis articulata woodlands, Pinus halepensis plantations, Shrublands, Cereal-almond crops and Cactus groves) in a semiarid area of northern Morocco using empirical data on 17 ecosystem services whose weights were established by 67 stakeholders. The analysis included MCA and direct ranking of the five land uses. Three groups of stakeholders (scientists and managers, collaborators, and direct users of natural resources) were particularly concerned by water supply, protection against erosion and floods, soil fertility and food provision. Multi-criteria analysis showed that the three groups concurred in that Tetraclinis woodlands, crops and cactus fields were the most suitable land uses for the area, regarding ecosystem service provision. Direct ranking confirmed this tendency but showed some divergence between the three groups, as collaborators and users were more inclined towards crops and cactus. The integration of the ecosystem services concept in land use planning is needed to be more practical and easily perceived as a logical response to environmental exigencies and social aspirations.  相似文献

In this viewpoint we draw on insights from participatory agri-environmental policy making, spatial planning and collaborative approaches to environmental management. We propose steps for planning, design and implementation of agri-environmental payment schemes that will encourage collaboration and co-ordinated actions at a landscape scale to contribute more effectively to the continued provision of ecosystem services.  相似文献

The ecosystem services concept and its political applications have been characterised by many scholars as manifestations of a neoliberal governmentality. However, the notion of ecosystem services can be linked to quite different policies and may thus lead to contradictory outcomes, depending on the context. It is largely unknown how policy-making in the field of nature conservation and landscape management in Germany will be influenced by the growing salience of the ecosystem services concept. The present study aims to close this gap by analysing the recent project “Natural Capital Germany – TEEB DE”. The objective is to examine the problematisations and rationalities of governing produced so far in the context of TEEB-DE and to assess them in the light of different ‘arts of government’. The most important finding is that the TEEB-DE discourse includes a relatively coherent neoliberal subdiscourse in terms of problematisations of governing, whereas with regard to rationalities it appears to be more polyphonic. The increased recognition of the ecosystem services concept in Germany as epitomised by TEEB-DE has so far not generated a consistent programme of neoliberal policy proposals. This is because TEEB-DE ties in with previous discourses in Germany that were mainly characterised by sovereign and disciplinary governmentalities, and interweaves them with the neoliberal framework of ecosystem services and natural capital.  相似文献

This study represents a first analysis of citizens’ willingness to pay (WTP) for agroecosystem services in a Baltic country (Lithuania). Since it is part of the European Union, Lithuania applied environmental agriculture schemes to support the production of agroecosystem services by farmers. Therefore, understanding the demand of such services may help policy makers to allocate funds. This study revealed that Lithuanian residents are concerned about environmental problems that may be caused by agriculture. Moreover, while the provision of agroecosystem services is demanded, citizens show very different tastes concerning these services. The application of a latent class model highlights three groups of citizens with different tastes and levels of WTP. Among the ecosystem services tested, the landscape provisions show the highest level of heterogeneity across the class. This study’s findings provide quantitative information concerning the demand for improvements in agroecosystem services through agri-environmental protection programmes. The obtained data supports the conclusion that choice experiments are a reliable tool to analyse consumers’ preferences related to environmental protection in Lithuania.  相似文献
