The expert valuation method for assessing agro‐environmental policy

The Contingent Valuation Method (CVM) and other conventional valuation methods of non‐market goods often prove to be unsuitable for the evaluation of the benefits of agro‐environmental policy. Therefore, a new method is introduced, according to which a group of experts jointly evaluates the strengths, weaknesses and finally monetary benefit of agro‐environmental programmes. While the methodology combines expert surveys, group discussions and CVM, its theoretical background is merit good theory. Compared to CVM, the most important practical difference in its outcome is the greater openness of the results. As an example, the Expert Valuation Method is applied to two groups of agro‐environmental policy measures in Switzerland. Suggestions for more efficient levels of reimbursements are made.     

A proposed methodology for measuring incremental environmental benefits from using constructed wetlands to control agricultural non-point-source pollution

A binary response estimation procedure using contingent valuation data is proposed for estimating the incremental environmental benefits associated with the use of constructed wetlands to control agricultural waste-water runoff. The model uses two binary responses per individual while circumventing the non-independence problems associated with follow-up valuation questions. Case study results suggest that the methodology provides a potentially effective means for measuring the non-market benefits of constructed wetlands in addition to water-quality maintenance.1998 Academic Press     

Assessing the benefits of community forests: an evaluation of the recreational use benefits of two urban fringe Woodlands

In 1989 the Countryside and Forestry Commissions launched a national programme to create Community Forests on the fringes of major towns and cities in England and Wales. The assumption that such forests will be of benefit to the community at large was tested by means of surveys of two existing multi‐purpose woodlands adjacent to major conurbations. Contingent valuation, travel cost and time cost methods of environmental valuation were used to estimate the existing user benefits of the two woodlands for recreation. The study highlights weaknesses in the travel cost approach when applied to recreational facilities located near urban fringe areas which can be accessed on foot. The results of the two surveys are discussed and compared with similar results for more rural woodlands/ forests. The study suggests that on social grounds at least the concept of Community Forests should be pursued with recreation benefits alone exceeding management costs by a factor of three.     

Perceiving Patagonia: An Assessment of Social Values and Perspectives Regarding Watershed Ecosystem Services and Management in Southern South America

Research on human dimensions of ecosystems through the ecosystem services (ES) concept has proliferated over recent decades but has largely focused on monetary value of ecosystems while excluding other community-based values. We conducted 312 surveys of general community members and regional researchers and decision-makers (specialists) to understand local perceptions and values of watershed ES and natural resource management in South America’s southern Patagonian ecoregion. Results indicated that specialists shared many similar values of ES with community members, but at the same time their mentalities did not capture the diversity of values that existed within the broader community. The supporting services were most highly valued by both groups, but generally poorly understood by the community. Many services that are not easily captured in monetary terms, particularly cultural services, were highly valued by community members and specialists. Both groups perceived a lack of communication and access to basic scientific information in current management approaches and differed slightly in their perspective on potential threats to ES. We recommend that a community-based approach be integrated into the natural resource management framework that better embodies the diversity of values that exist in these communities, while enhancing the science-society dialog and thereby encouraging the application of multiple forms of ecological knowledge in place-based environmental management.     

Application of Resource Assessment Data to Policy Decisions in Developing Countries

Information about a nation's mineral resource potential is important in regional and national development planning. Unfortunately, it is usually not possible to determine the optimum levels of investment in mineral resource assessment activities in a developing country. In addition, there is a tendency for governments to initiate expensive resource assessment projects without an understanding of the types of decision that may be influenced by the assessment data. This paper examines ten major policy issues where decisions can be substantially influenced by resource assessment information. Governments can expect to increase their benefits from investment in resource assessment activities by linking resource assessments to specified policy decisions.     

Geoscientific maps as an aid to land use and regional planning

Successful regional and land use planning today requires an optimal use of available natural resources. Geoscientific maps of the natural environment's potential satisfy the geoscientific part of this requirement. These maps are presented for politicians, laymen and planners in easily understood form as simple thematic maps (for soil, groundwater, mineral deposits, geological engineering, proposals for priority utilization from the geoscientific point of view and other geological facts important to society). In this way optimal use of the geogenic potential at specific places is made possible.     

ASSESSING THE ECONOMIC BENEFITS OF GROUND WATER FOR ENVIRONMENTAL POLICY DECISIONS1

ABSTRACT: The full range of environmental and economic services of ground water need to be accounted for in policy decisions. Non-recognition of these services imputes a lower value for the ground water resource in establishing policies. We describe a conceptual framework for identifying and measuring the economic value of groundwater. The valuation framework links changes in physical characteristics of ground water to services provided by ground water and the economic effects of changes in ground water services. In addition to the framework, we develop a general protocol to follow for assessing the benefits of ground water policies. Application of the protocol will aid in establishing structure and consistency across policy assessments and improve the accuracy and completeness of benefit estimates, avoid double-counting problems, and eliminate duplication of ground water valuation efforts.     

Country-scale phosphorus balancing as a base for resources conservation

In order to effectively conserve the non-renewable resource phosphorus (P), flows and stocks of P must be known at national, regional and global scales. P is a key non-renewable resource because its use as fertilizer cannot be substituted posing a constraint on the global food production in the long-term. This paper presents a methodology to establish country-wide P balances that emphasises resource use. We develop a material flow analysis (MFA) model that comprises all relevant flows and stocks of P in five subsystems, seven processes and 36 material flows. For quantification, statistical data from economic and agricultural sources as well as available information about P partitioning in natural and anthropogenic processes are used. Special attention is paid to data gaps and uncertainties. The model was tested in two case studies on P management in Turkey and Austria. MFA appears to be a tool well suited for establishing country-wide P balances, provided that national statistics are well-structured and accessible. If a common approach is used for modelling P-flows and stocks, regional and national balances can be compared and linked towards larger scale P balances for an improved management of the resource.     

Mineral resources appraisal and policy: Controversies,issues and the future

Political-economic events of the 1970s brought mineral resource appraisal to the focus of national policy. Estimates of and methodologies for mineral resources appraisal were scrutinized, revealing deficiencies in method and data and fostering considerable debate about the credibility of estimates and about preferred methodology. Since credibility can be increased through the acquisition of additional geoscience information, questions regarding methodology have more than one formulation and therefore more than one correct solution, depending upon the expected value of additional information and the conditional losses of relevant policy options. When existing information is meagre and the expected value of information is high, the optimum decision may be to defer all policy options until after the acquisition and analysis of- additional information. Decision theory offers an analytical framework that is sufficiently generalized to provide answers for highly varied circumstances of geoscience and resource information and policy issues. Our ability to perform any such analysis is limited by inaccuracies in both geologists' estimates of undiscovered mineral resources, and in economists' calculations of conditional losses of policy options for each of the relevant states of mineral resources.     

An Interpretive Approach to Developing Volunteer-based Coastal Monitoring Programmes

The concept of sustainable development has highlighted the need to involve those who use a natural resource in helping to manage and maintain it. This has prompted the development of monitoring programmes involving volunteers who collect scientific data on the state of the natural environment. This paper argues that interpretation theory and practice provide a sound basis for the design and implementation of volunteer-based coastal monitoring programmes. Integration of multiple interrelated objectives in programmes relies on sound 'audience' research, including planned evaluation procedures. Three case-studies are presented which serve to identify and highlight the benefits of broadening the primary scientific focus of monitoring programmes to include greater consideration of participant motivations, skills and knowledge in the design and delivery of programmes. Discussion in this paper focuses on coastal monitoring programmes but the stated benefits might also be expected when applying this approach to other natural resource monitoring programmes.     

The relationship between mining and socio-economic well being in Australia’s regions

This paper examines the relationship between quality of life indicators and the gross value of minerals production from Australian regions. We used quality of life indicators, aggregated for 71 local government areas containing mining activities, of household income, housing affordability, access to communication services, educational attainment, life expectancy, and unemployment. We find no evidence of systematic negative associations between quality of life and the gross value of minerals production. Instead, mining activity has a positive impact on incomes, housing affordability, communication access, education and employment across regional and remote Australia. Whilst we do not establish causality between mining activity and quality of life, our analysis prompts a rethink of the resource curse as it applies within a single country. We did not find evidence of a resource curse, at the local government level, in Australia’s mining regions. Nevertheless, we note observations by many other researchers of negative social impacts on specific demographic sectors, localities, families of fly-in fly-out mining operations, and individuals. This contrast may be a scale issue, with the regional benefits of mineral wealth masking highly localised inequalities and disadvantage. We suggest that there is a need to better understand these impacts and, more importantly, the types of policy mechanisms government and industry can adopt to mitigate or avoid them.     

Useful indicators of urban sustainability: Some methodological issues

This paper considers methodological questions concerning indicators of sustainability, which have arisen in the course of an EPSRC-supported project investigating a systems approach to assessing the sustainability of cities. The project aimed: (a) to develop a methodology, the Reference Sustainability System (RSS), for representing the energy, resource and material flows, on which the environmental sustainability of cities depends; (b) to show how this methodology could contribute to a more systematic assessment of the potential of technological and resource management strategies to enhance urban sustainability. Systems models of the material or resource flows caused by the household demand for paper, energy, water and bottled water have been constructed. The project has highlighted the complexity of assessing the contributions of specific technologies and strategies to enhanced sustainability. Particular issues raised include the relative merits and problems of using externality valuation methods compared to physical indicators, the difficulties of aggregating environmental impacts, the question of where system boundaries should be drawn in a life cycle analysis, and the need to consider both distant and local impacts which arise from the end-use demands of urban populations. The paper explores these issues, through the use of modelling results from the case studies. Particular emphasis is placed on the communication of research results to policy makers, interested organisations and the public, drawing on recent experience with the dissemination of results from the project's first case study relating to waste-paper management options.     

Valuation of Ecological Resources and Functions

/ Ecological resources are natural resources that provide certain necessary but overlooked system maintenance functions within ecosystems. Environmental economics is in search of an appropriate analysis framework to determine economic values of such resources. This paper presents a framework that estimates and compiles the components of value for a natural ecosystem. The framework begins with the ecological processes involved, which provide functions within the ecosystem and services valued by humans. We discuss the additive or competive nature of these values, and estimate these values through conventional and unconventional techniques. We apply the framework to ecological resources in a shrub-steppe dryland habitat being displaced by development. We first determine which functions and services are mutually exclusive (e.g., farming vs soil stabilization) and which are complementary or products of joint production (e.g., soil stabilization and maintenance of species). We then apply benefit transfer principles with contingent valuation methodology (CVM), travel cost methodology (TCM), and hedonic damage pricing (HDP). Finally, we derive upper-limit values for more difficult-to-value functions through the use of human analogs, which we argue are the most appropriate method of valuation under some circumstances. The highest values of natural shrub-steppe habitat appear to be derived from soil stabilization.KEY WORDS: Natural resource economics; Ecological economics; Ecological resources; Shrub-steppe; Environmental valuation; Cost; Benefit; Value     

Community values for environmental protection in a cane farming catchment in northern Australia: a choice modelling study

Choice modelling is an emerging approach to estimating the non-use values of environmental services with multiple attributes. In this paper, results are reported of a choice modelling study conducted in the Herbert River District of North Queensland to estimate the value placed on the protection of natural vegetation in areas suitable for cane production by the local community. Resource use options that vary in the level of environmental protection and the level of agricultural production were presented as a series of choice sets and respondents were asked to choose among a set of three discrete alternatives in a given choice set. The alternatives in each choice set were described by four attributes, pertaining to the area of teatree woodlands, the area of vegetation along rivers and in wetlands, regional income from cane production, and an environmental levy. The responses were analysed together with socio-economic data using a nested-logit discrete-choice model to estimate the community willingness-to-pay for the protection of natural vegetation. The results indicate that the environmental values of wetlands are comparable to returns from commercial production of sugar cane and that the values of teatree woodlands are comparable to returns from extensive grazing. It is argued that land allocation policies should recognise these values in tandem with commercial benefits of production to ensure that resources are used more efficiently.     

Methodology of industry scale analysis under the constraint of regional resource capacity using HSY algorithm

This paper develops a methodology of proper scale analysis for regional industry development, which can be used in industry planning with the consideration of regional resource capacities. In the face of different data sources and even data scarcity, alternative methods based on linear programming and quadratic programming algorithms for calculating the resource intensity factors are designed. Based on the empirical study of industrialization, initial scenarios of industry development were set. Using HSY algorithm, sensitive industries that may cause exceeding regional resource capacity can be identified, and the risk of exceeding can be predicted and expressed in probability. Furthermore, a proper scale range can be designed for these sensitive industries according to resource capacity. Taking the case of Dalian city in China, this paper estimated the regional urban development plan, various resources capacities were studied, and land resources were estimated to be the most critical resource for the city. The land resource depletion intensities of different industries are calculated by quadratic programming algorithm. Under the constraint of 427.56 km² available industrial land resources, the electronic and power industries have the most significant impact on total land use, if the scale of power industry exceeds 1.27 billion USD, the probability of land resource capacity breakthrough will be 50%.

Local and Regional Partnerships in Natural Resource Management: The Challenge of Bridging Institutional Levels

Although collaboration and multi-stakeholder partnerships have become a common feature in natural resource management throughout the world, various problems are associated with attempts to up-scale community-based natural resource management from the local to the regional level. To analyze the reasons behind these problems, this article reports on two examples of collaboratives in Australia: local Landcare groups, and regional natural resource management (NRM) bodies. Recent government-induced changes have shifted the focus from local Landcare group action to strategic planning and implementation by regional NRM bodies. Two typologies of collaboratives are applied to analyze the characteristics of both these groups. The study uses data from 52 qualitative interviews with key informants at the local and regional level in Victoria and Tasmania, participant observation, as well as literature and document analysis. The article illustrates how the groups’ distinct characteristics can cause conflicts when the different types of collaboratives operate in parallel. In addition, the article reports how stakeholders perceive the level of community participation in decision-making processes. The key message is that the benefits of community participation and collaboration that arise at the local level can be lost when these approaches are up-scaled to the regional level unless there is an intermediary or ‘mediating structure’ to facilitate communication and create the link between different types of collaboratives.     

Sustainable urban planning and the brownfield development process in the United Kingdom: Lessons from the Thames Gateway

Over recent decades urban and regional development agendas in the United Kingdom have become dominated by the discourses of sustainable development, holistic regeneration and community capacity-building. It is in this context that brownfield development has emerged as a core feature in strategies to regenerate urban areas. Bringing brownfields back into use tends to be, a priori, presented as a 'good thing' that will have broader economic, environmental and social benefits. This paper assesses the role that brownfield development plays in urban and regional policy agendas in the UK. It begins by identifying the rationales for, and concerns associated with, the brownfield development process in the UK, before discussing the trajectories of policy under the New Labour government since 1997. It argues that at present too much is expected from brownfield-led regeneration programmes and that wider benefits will only accrue if these programmes are embedded within a wider and more comprehensive set of development projects and policy agendas.     

Perceptions of Community Benefits from Two Wild and Scenic Rivers

Wild and Scenic Rivers provide a host of psychological, social, ecological, and economic benefits to local communities. In this study, we use data collected from recreational users of two Wild and Scenic Rivers to examine perceptions of the benefits provided by the rivers to local communities. Our purposes are (1) to determine if similar perceptions of community benefits exist across the two rivers, (2) to determine if individuals’ proximity to the rivers are related to the benefits they perceive, (3) to determine if individuals’ prior recreation experience on the river is related to variations in perceived benefits, (4) to determine if users’ sociodemographic characteristics are related to perceived community benefits, and (5) to determine if the influence of these characteristics on perceived community benefits is similar across the two resource areas. Perceived benefits were found to be analogous across both rivers as individuals consistently ranked ecological/affective benefits as well as tangible benefits similarly. Recreationists living further from the river ranked ecological and affective benefits as significantly less important than those individuals living closer to the river. Women perceived the community benefits produced by the resource areas to be significantly more important when compared to men. Significant relationships were also found between perceived benefits and recreationists’ previous use of the river, their age, and their level of education. With the exception of resource proximity and prior use history, the effects of user characteristics on perceived community benefits were not statistically different across the two rivers. These findings imply similar patterns of perceived community benefits exist across distinct resource areas and that the relationships between user characteristics and perceived benefits are also similar across the study rivers.     

Evaluating the accuracy of the benefit transfer method: a rural water supply application in the USA.

Due to declining federal, state, and local government budgets, there is an increasing need to analyze the benefits of government funded programs to determine where increasingly limited funds would best be spent. The benefits transfer technique is analyzed for the development of a rural water supply system and guidelines for successful benefits transfer are presented. Benefit transfer appears to provide reasonably accurate estimates of natural resource benefits if a broad based benefit model is used. The benefits-transfer-based estimates are accurate as long as a model based on data from a wide variety of conditions is used or the model is based on data from a very similar region. The wide-based data modeling approach has the greatest practical application. These findings are based upon contingent valuation data obtained from four sites in the western USA.
