Land Preservation in British Columbia: An Empirical Analysis of the Factors Underlying Public Support and Willingness to Pay AgEcon
Androkovich, Robert A.; Desjardins, Ivan; Tarzwell, Gordon; Tsogaris, Peter.
This study extends previous empirical research on land preservation by considering an actual land preservation scheme, the agricultural land reserve in British Columbia, Canada. The reserve was established in 1973 to ensure that development did not occur on the province’s most productive agricultural land. ‘To ensure that local food production is maintained,’ ‘the economic importance of British Columbia’s agricultural sector,’ and ‘to protect the environment’ are the most important factors that underlie support for the reserve. Aggregate, provincewide willingness to pay to maintain the land reserve is substantial, with our most conservative estimate being Can$91.18 million per year.

Many Eyes on Nature: Diverse Perspectives in the Cape Horn Biosphere Reserve and Their Relevance for Conservation Ecology and Society
Berghoefer, Uta; Helmholtz Centre for Environmental Research - UFZ; uta.berghoefer@gmx.de; Rozzi, Ricardo; University of North Texas; Universidad de Magallanes (Chile); rozzi@unt.edu; Jax, Kurt; Helmholtz Centre for Environmental Research - UFZ; kurt.jax@ufz.de.
Relationships between humans and nature take multiple forms. This is a fundamental issue in conservation but one that is often neglected, leading to poor conservation outcomes. It is thus imperative that we come to understand better the complex relationships between humans and nature. To do so, we need to examine “nature” and the often assumed dichotomy between humans and nature. We conducted a qualitative social research inquiry to explore the societal relationships with nature in the Cape Horn Biosphere Reserve in Chile. From the results, we developed a framework that illustrates how different “natures” are created in the three-way relationship among the individual, society, and the physical world. We further...

Merging capabilities and livelihoods: analyzing the use of biological resources to improve well-being Ecology and Society
Lienert, Juri; University of Basel, Department of Social Sciences, Sustainability Research Group; juri.lienert@gmail.com; Burger, Paul; University of Basel, Department of Social Sciences, Sustainability Research Group; paul.burger@unibas.ch.
Especially poor people in developing countries depend on biological resources to manage their livelihoods and to generate income. Because these resources are usually public goods, their use is often subjected to what is known as the tragedy of the commons, potentially leading to resource depletion, environmental degradation, and loss of biodiversity, which consequently undermines the availability and capacity of resources to contribute to residents’ well-being in the long run. We suggest addressing this typical sustainability issue from a new angle. Against the backdrop of identifiable shortcomings within two popular analytic approaches, the capability approach (CA) and the sustainable livelihood approach (SLA), we argue for an improved...

Nature value: the evolution of this concept Ciência e Agrotecnologia
Silva,Sabrina Soares da; Reis,Ricardo Pereira; Ferreira,Patrícia Aparecida.
More attention has been paid to environmental matters in recent years, mainly due to the current scenario of accentuated environmental degradation. The economic valuation of nature goods can contribute to the decision-making process in environment management, generating a more comprehensive informational base. This paper aims to present, in a historic perspective, the different concepts attributed to nature goods and were related to the current predominant perspectives of nature analyses. For this purpose, this paper presents the different concepts attributed to value since the pre-classical period, when nature were viewed as inert and passive providers of goods and services, this view legitimized nature's exploration without concern over the preservation...

On the Valuation of Companies with Growth Opportunities AgEcon
Dapena, Jose Pablo.
Each company faces day to day investment opportunities. Just by staying in business the company is taking a decision of reinvesting capital. These opportunities have to be fairly valued to overcome misallocation of resources. A project with high growth opportunities requires high reinvestments to take full advantage of them until it reaches its mature stage. These investments can be seen as a succession of call options on future growth. When a company with such prospects is valued using the discounted cash flow technique and growth is taken implicitly in the growing cash flows and the residual value, the value thus obtained will be higher than the true one (under certain circumstances). Technology advances and the effects of globalization create enormous...

Practical application of the Ecosystem Service Approach (ESA): lessons learned and recommendations for the future ArchiMer
Beaumont, Nicola J; Mongruel, Remi; Hooper, Tara.
An Ecosystem Service Approach (ESA) is increasingly advocated for use in both environmental management and academic applications. However, despite extensive conceptual development, there are still very few examples of the effective use of the ESA for operational management. This contribution reports on the field application of the ESA at six marine and coastal case study sites. Each case study demonstrates a variation on an interdisciplinary approach to translate complex natural science data into ecosystem service terminology, and then explores the usefulness of this information in a management context. From these experiences 6 key recommendations are made to aid the future application of the ESA: (1) Invest resources in collective planning of ESA; (2)...

RESULTS OF THE NORTH DAKOTA LAND VALUATION MODEL FOR THE 2001 AGRICULTURAL REAL ESTATE ASSESSMENT AgEcon
Aakre, Dwight G.; Vreugdenhil, Harvey G..
This report summarizes the results of the North Dakota Land Valuation Model. This model is used annually to estimate average land values by county, based on the value of production produced on that land. The county land values developed from this procedure form the basis for the 2001 valuation of agricultural land for assessment of real estate taxes. The average all land value from this analysis is multiplied by the total acres of agricultural land on the county abstract to determine each county's total agricultural land value. The State Board of Equalization compares this value with the total value assessed to agricultural property in each county. Each county is required by state statute to assess a total value of agricultural property within 5 percent of...

Some External Costs of Dairy Farming in Canterbury AgEcon
Tait, Peter R.; Cullen, Ross.
Intensification of agricultural practices is occurring in Canterbury. Dairy farm conversions continue with land use increasing 132% since 1995. Current concerns emanate predominantly from issues of water quantity and quality, in particular the degradation of lowland streams. These and other costs are not transmitted through markets for dairy products, these negative externalities represent allocation and equity concerns for regional policy makers. This study canvassed regional policy administrators, assembled available valuation studies and performed rudimentary calculations based on reviewed New Zealand literature to form an estimate of the external costs of dairy farming in Canterbury. External costs are estimated at $28.7 to $45 million annually. Using...

Stated Choice Experiments with Complex Ecosystem Changes: The Effect of Information Formats on Estimated Variances and Choice Parameters AgEcon
Hoehn, John P.; Lupi, Frank; Kaplowitz, Michael D..
Stated choice experiments about ecosystem changes involve complex information. This study examines whether the format in which ecosystem information is presented to respondents affects stated choice outcomes. Our analysis develops a utility-maximizing model to describe respondent behavior. The model shows how alternative questionnaire formats alter respondents’ use of filtering heuristics and result in differences in preference estimates. Empirical results from a large-scale stated choice experiment confirm that different format presentations of the same information lead to different preference parameter estimates and error variances. A tabular format results in choice parameter estimates with statistically smaller variances than parameters estimated from...

The Benefits of Air Pollutant Emissions Reductions in Maryland: Results from the Maryland Externalities Screening and Valuation Model AgEcon
Austin, David H.; Krupnick, Alan J.; Burtraw, Dallas; Stoessell, Terrell.
This paper reports the results of policy simulations of environmental and human health externalities arising from the production of electricity. The primary purpose of this paper is to illustrate the Maryland Externalities Screening and Valuation Model, developed for the State of Maryland's Department of Natural Resources. A secondary purpose is to estimate likely Maryland benefits from Title IV emissions reductions at electric power generation facilities. Sources and scope of benefits, and the potential of policy to achieve specific environmental and human health goals, are suggested by the results. We find that expected health benefits from reductions in power plant emissions dominate the estimated benefits of improved recreational visibility and...

There is an increasing emphasis on the restoration of ecosystem services as well as of biodiversity, especially where restoration projects are planned at a landscape scale. This increase in the diversity of restoration aims has a number of conceptual and practical implications for the way that restoration projects are monitored and evaluated. Landscape-scale projects require monitoring of not only ecosystem services and biodiversity but also of ecosystem processes since these can underpin both. Using the experiences gained at a landscape-scale wetland restoration project in the UK, we discuss a number of issues that need to be considered, including the choice of metrics for monitoring ecosystem services and the difficulties of assessing the interactions...

The economic cost of wetland destruction AgEcon
Schmidt, Carmel Elizabeth.
Wetlands are often refereed to as the ‘kidney of the river’, but what is the value of the water filtration they provide, and what is the cost of wetland destruction? This paper determines the economic value of wetlands for water filtration. It demonstrates that wetlands are of considerable economic value, even where the volume of water filtered is in excess of that required for domestic consumption. It argues that if legislation required those who destroy natural wetlands to replace the water filtration process the wetlands once provided, it would be necessary to construct water filtration plants at significant cost.

THE INFLUENCE OF SPATIAL LAND USE PATTERNS ON RURAL AMENITY VALUES AND WILLINGNESS TO PAY FOR GROWTH MANAGEMENT: EVIDENCE FROM A CONTINGENT CHOICE SURVEY AgEcon
Johnston, Robert J.; Bauer, Dana Marie; Swallow, Stephen K..
This paper reports on a contingent choice study in which residents of a rural Rhode Island community were asked to express their preferences for packages of growth management outcomes, where surveys presented both spatial and non-spatial attributes of growth management outcomes. Survey results provide insight on the extent to which estimated willingness to pay (WTP) for marginal changes in specific landscape features or land uses may be influenced by spatial considerations. Results also characterize the potential impact of spatial context on public preferences and WTP for coordinated packages of growth management outcomes. Keywords: Land Use, Spatial, Contingent Choice, Growth Management, Economics, Valuation

The Payment Vehicle Used in CV Studies of Environmental Goods Does Matter AgEcon
Ivehammar, Pernilla.
This paper examines the effect of the payment vehicle on the valuation of an environmental good with the contingent valuation method (CVM). Results from three CV studies comparing different payment vehicles by using split samples when valuing environmental encroachment caused by roads in Sweden are presented and compared to results from other such split-sample studies of payment vehicle effects. The results are consistent and show that the payment vehicle affects the valuation, but not always the way expected when considering incentives to behave strategically.

Using Experimental Auctions for Marketing Applications: A Discussion AgEcon
Lusk, Jayson L..
The present article discusses general issues associated with experimental auctions and their relative advantages and disadvantages over other marketing research techniques. Experimental auctions create an active market environment with feedback where subjects exchange real goods and real money, which is not generally the case with other methods. The article also discusses four experimental design issues associated with experimental auctions: auction mechanism, market feedback and bidder affiliation, demand reduction and wealth effects, and multiple attribute valuation. Each of these experimental design issues, if not properly controlled, have the potential to create serious flaws in marketing recommendations.
