Are Agricultural Values a Reliable Guide in Determining Landowners’ Decisions to Create Carbon Forest Sinks? AgEcon
Shaikh, Sabina L.; Sun, Lili; van Kooten, G. Cornelis.
This research examines the effects of various factors on farmer participation in agricultural tree plantations for economic, environmental, social and carbon-uptake purposes, and potential costs of sequestering carbon through afforestation in western Canada. Using data from a survey of landowners, a discrete choice random utility model is used to determine the probability of landowners’ participation and corresponding mean willingness to accept (WTA) compensation for a tree-planting program. WTA includes positive and negative benefits to landowners from planting trees, benefits not captured by foregone returns from agricultural activities on marginal land. Estimates of WTA are less than foregone returns, but even so average costs of creating carbon credits...

DOES INCLUSION OF LANDOWNERS' NON-MARKET VALUES LOWER COSTS OF CREATING CARBON FOREST SINKS? AgEcon
Shaikh, Sabina L.; Suchanek, Pavel; Sun, Lili; van Kooten, G. Cornelis.
This research examines effects of various factors on farmer participation in agricultural tree plantations for economic, environmental, social and carbon-uptake purposes. Using data from a survey of Canadian agricultural landowners, a discrete choice random utility model is used to determine the probability of farmers' participation and corresponding mean willingness to accept (WTA) compensation for a tree-planting program. WTA includes positive and negative nonmarket benefits to landowners from planting trees. Estimates of WTA are less than foregone agricultural rents, but average costs of creating carbon credits still exceed their projected value under a CO2-emissions trading scheme

EXPERT OPINION VERSUS TRANSACTION EVIDENCE: USING THE REILLY INDEX TO MEASURE OPEN SPACE PREMIUMS IN THE URBAN-RURAL FRINGE AgEcon
Cotteleer, Geerte; Stobbe, Tracy; van Kooten, G. Cornelis.
Due to economic and population growth farmland and to a lesser extend other undeveloped areas are under pressure in the urban-rural fringe in British Columbia, Canada. The objectives of this paper are to determine if residential property values near Victoria, BC include open-space premiums for farmland or parks or both, and to determine if using assessed values instead of market prices of the property result in the same findings. We estimate a SUR (Seemingly Unrelated Regression) model with two hedonic pricing equations, one with actual market values as the dependent variable and one with assessed property values, and compare the resulting estimates of shadow prices for open space amenities. Furthermore, we take account of spatial autocorrelation and...

Land Degradation in Ethiopia: What do Stoves Have to Do with it? AgEcon
Gebreegziabher, Zenebe; van Kooten, G. Cornelis; van Soest, Daan P..
Land degradation is a particularly vexing problem in developing countries; as forests are depleted, crop residues and dung are used for fuel, which degrades cropland. In Ethiopia, the government encourages tree planting and adoption of energy efficient stove technologies to mitigate land degradation. We use data from 200 households in Tigrai, Ethiopia to examine the adoption of new stove technologies. Adoption is an economic decision, related to savings in time spent collecting fuel and cooking, and cattle required for everyday purposes. Results indicate adopters of efficient stoves reduce respective wood and dung use by 68 and 316 kg per month.

The Ghost of Extinction: Preservation Values and Minimum Viable Population in Wildlife Models AgEcon
van Kooten, G. Cornelis; Eiswerth, Mark E..
The inclusion of a minimum viable population in bioeconomic modeling creates at least two complications that are not resolved by using a modified logistic growth function. The first complication can be dealt with by choosing a different depensational growth function. The second complication relates to the inclusion of the in situ benefits of wildlife into the analysis. Knowledge about the magnitude of the in situ benefits provides no guide for policy about conservation management. Simply knowing that people are willing to pay a large amount each year to protect a species says nothing about whether one should manage habitat to protect or enhance the species’ numbers, unless the species is in imminent danger of extinction. If willingness to pay is to be a...

Fuzzy Logic and Preference Uncertainty in Non-market Valuation AgEcon
Sun, Lili; van Kooten, G. Cornelis.
In seeking to value environmental amenities and public goods, individuals often have trouble trading off the (vague) amenity or good against a monetary measure. Valuation in these circumstances can best be described as fuzzy in terms of the amenity valued, perceptions of property rights, and the numbers chosen to reflect values. In this paper, we apply fuzzy logic to contingent valuation, employing a fuzzy clustering approach for incorporating preference uncertainty obtained from a follow-up certainty confidence question. We develop a Fuzzy Random Utility Maximization (FRUM) framework where the perceived utility of each individual is fuzzy in the sense that an individual’s utility belongs to each cluster to some degree. The model is then applied to a...

Farmland Conservation in the Netherlands and British Columbia, Canada: A Comparative Analysis Using GIS-Based Hedonic Pricing Models AgEcon
Cotteleer, Geerte; Stobbe, Tracy; van Kooten, G. Cornelis.
As a result of urban development farmland in many countries is under pressure. Reasons to preserve farmland are related to cultural heritage, food safety, open space, the environment, but also slowing and restricting development is a reason. To protect farmland countries use different land use policies. This paper will look specifically at two jurisdictions: The Netherlands and a particularly rich farming area in British Columbia, Canada. For these areas we will investigate how the institutions and laws present in these jurisdictions contribute to agricultural land preservation. We will analyse farmland values in a GIS-based hedonic pricing framework to answer this question. This combination enables us to analyse direct impacts of laws and regulations...

Protecting the African Elephant: A Dynamic Bioeconomic Model of Ivory Trade AgEcon
van Kooten, G. Cornelis.
International trade in ivory is banned in order to protect the African elephant. The trade ban is supported by some range states, because it is seen as an effective means for protecting a 'flagship' species, but is opposed by states, mainly in southern Africa, because populations exceed the carrying capacity of local ecosystems. Issues concerning the ivory trade ban are addressed in this paper using a dynamic partial-equilibrium trade model that consists of four ivory exporting regions and a single demand region. Results indicate that a trade ban might not be successful in maintaining elephant populations, even if it leads to a stigma effect that reduces demand and increases the marginal costs of marketing ivory. Results suggest that the species will...

Quality of Life as an Explanation of the Divergence between Ranchers’' WTA and WTP for Public Forage AgEcon
Sun, Lili; van Kooten, G. Cornelis; Voss, Graham M..
This research provides empirical support for divergence between WTA and WTP, based on results from a 2002 survey of Nevada ranchers. WTP for public forage and WTA compensation to part with grazing rights are estimated simultaneously, with the estimators demonstrating a statistically significant divergence while enabling identification of ranch characteristics that influence the discrepancy in valuations. We conclude that ranching lifestyle (quality of life) accounts for some of the difference between WTP and WTA.

AN ALTERNATIVE APPROACH TO THE EVALUATION OF GOAL HIERARCHIES AMONG FARMERS AgEcon
van Kooten, G. Cornelis; Schoney, Richard A.; Hayward, Keith A..
Results of a study of goal orderings of Saskatchewan farmers who participate in the province's FARMLAB Program are presented. We use the method of fuzzy pair-wise comparisons which allows the respondent to indicate a degree of preference between two alternative goal statements, thereby providing more information than in the binary case. From survey data ratio-scale scores are constructed for eight goal statements, and these are regressed on a set of farm enterprise and household characteristics and a psychological locus-of-control (or I-E) score. The empirical results indicate that goodness-of-fit measures are better than those obtained by other researchers, perhaps because a psychological measure (I-E score) is included as an explanatory variable for...

ARE LOG MARKETS COMPETITIVE? EMPIRICAL EVIDENCE AND IMPLICATIONS FOR CANADA-U.S. TRADE IN SOFTWOOD LUMBER AgEcon
Niquidet, Kurt; van Kooten, G. Cornelis.
Under the U.S. Department of Commerce’s ‘changed circumstances’ review, it is possible that the countervail duty on Canadian lumber can be lowered if administered stumpage prices are based on transaction evidence appraisal – on actual auction data and regression analysis. The Province of British Columbia is implementing such a marketbased approach to set stumpage fees, relying on timber auction data from the Small Business Forest Enterprise Program (SBFEP) and OLS regression. We employ SBFEP data to estimate a truncated regression model, comparing our estimates of stumpage fees with the OLS results. It turns out that the OLS approach is biased and likely results in overestimates of stumpage in some timber stands and underestimates in others. Further, we...

Utility-scale Wind Power: Impacts of Increased Penetration AgEcon
Pitt, Lawrence; van Kooten, G. Cornelis; Love, Murray; Djilali, Ned.
Intermittent renewable energy sources such as wind, solar, run-of-river hydro, tidal streams and wave fluxes present interesting challenges when exploited in the production of electricity, which is then integrated into existing and future grids. We focus on wind energy systems because they have an emerging presence, with new installed capacity approaching 8 GW annually. We survey many studies and compile estimates of regulation, load following and unit commitment impacts on utility generating assets with increasing wind penetration. Reliability (system reserve), observed capacity factors and the effective capacity (ability to displace existing generation assets) of wind energy systems are discussed. A simple energy balance model and some results from...

Bio-energy from Mountain Pine Beetle Timber and Forest Residuals: The Economics Story AgEcon
Niquidet, Kurt; Stennes, Brad; van Kooten, G. Cornelis.
In light of the large volumes of pine killed in the Interior forests in British Columbia by the mountain pine beetle, many are keen to employ forest biomass as an energy source. To assess the feasibility of a wood biomass-fired power plant in the BC Interior it is necessary to know both how much physical biomass might be available over the life of a plant, but also its location because transportation costs are likely to be a major operating cost for any facility. To address these issues, we construct a mathematical programming model of fiber flows in the Quesnel Timber Supply Area of BC over a 25-year time horizon. The focus of the model is on minimizing the cost of supplying feedstock throughout space and time. Results indicate that over the life of the...

Economics of Forest Ecosystem Carbon Sinks: A Review AgEcon
van Kooten, G. Cornelis; Sohngen, Brent.
Carbon terrestrial sinks are seen as a low-cost alternative to fuel switching and reduced fossil fuel use for lowering atmospheric CO2. In this study, we review issues related to the use of terrestrial forestry activities to create CO2 offset credits. To gain a deeper understanding of the confusing empirical studies of forest projects to create carbon credits under Kyoto, we employ meta-regression analysis to analyze conditions under which forest activities generate CO2-emission reduction offsets at competitive ‘prices’. In particular, we examine 68 studies of the costs of creating carbon offsets using forestry. Baseline estimates of costs of sequestering carbon are some US$3–$280 per tCO2, indicating that the costs of creating CO2-emission offset credits...

Economics of Forest and Agricultural Carbon Sinks AgEcon
van Kooten, G. Cornelis.
As a result of the Kyoto Protocol (KP) and its so-called "flexibility mechanisms", climate change and mechanisms to mitigate its potential effects have attracted considerable economic and policy attention. A major reason for this attention is that the KP has a complex set of instruments that enable countries to achieve emissions reduction targets in a wide variety of ways, some of which are unlikely to lead to real, long-term reductions in greenhouse gas emissions. One purpose of this chapter, therefore, is to provide an overview of economic reasoning applied to climate change and to illustrate how terrestrial carbon uptake credits (offset credits) operate within the KP framework. Attention is focused on the feasibility of terrestrial carbon sinks to slow...

Wind Power Development: Opportunities and Challenges AgEcon
van Kooten, G. Cornelis; Timilsina, Govinda R..
In this study, the prospects of wind power at the global level are reviewed. Existing studies indicate that the earth’s wind energy supply potential significantly exceeds global energy demand. Yet, only 1% of the global electricity demand is currently derived from wind power despite 40% annual growth in wind generating capacity over the last 25 years. More than 98% of total current wind power capacity is installed in the developed countries plus China and India. Existing studies estimate that wind power could supply 7% to 34% of global electricity needs by 2050. Wind power faces a large number of technical, financial, institutional, market and other barriers. To overcome these, many countries have employed various policy instruments, including capital...
