The Effects of Scenic and Environmental Amenities on Agricultural Land Values

Ascribing land value solely to productive capacity does not accurately capture the impact environmental amenities provide on western land prices. Agricultural land prices in Wyoming are estimated using a hedonic price model and Geographic Information Sciences (GIS) data. These GIS measurements include on-parcel wildlife and fish habitat, viewscape attributes and distance to protected federal lands. A feasible generalized least squares (FGLS) approach is used to address both spatial autocorrelation and heteroscedasticity. The estimation is robust and highly significant. Results indicate that amenities as well as productivity are significant in explaining land values for the sample analyzed. Such information is useful for landscape management in the face of amenity threatening parcel fragmentation.Environmental Economics and Policy, Land Economics/Use,

Determinants of Agricultural Landowners’ Willingness to Supply Open Space Through Conservation Easements

Open space provides a range of benefits to many people of a community, beyond the benefits that accrue to private landowners. Parks and natural areas can be used for recreation; wetlands and forests supply storm-water drainage and wildlife habitat; farms and forests provide aesthetic benefits to surrounding residents. Moreover, undeveloped land can give relief from congestion. Agricultural lands are an important source of open space, but many of these lands are under great development pressure. One tool that is currently being used to aid in the preservation of open space by landowners is conservation easements. The rate of land protection by state and local land trusts has tripled since the beginning of the decade, and the West is the fastest growing region for both the number of acres under conservation easements and number of land trusts according to the Land Trust Alliance. Given the increased demand for amenities provided by private agricultural lands and the increased use of conservation easements, it is interesting to note that there is a paucity of research related to landowners’ preferences regarding conservation easements. The specific research objective of this paper is to determine important factors affecting an agricultural landowners’ potential choice regarding the placement of a parcel of land under a conservation easement. Knowing these factors could be useful to communities, public organizations and land trusts trying to provide open space to meet a growing demand for this public good. Information to construct a survey was obtained through a series of focus groups held in Wyoming and Colorado. Results from these focus groups were then used to develop twelve versions of a stated choice survey instrument. The first part of the survey included questions about the landowner’s specific community. These Likert scale questions were to designed to elicit a measurement of the respondents’ “sense of place” regarding his or her community. The second part of the survey questioned participants about their land and their land’s attributes, including what the landowner felt his land was worth, types of production and non-production activities land was used for, the types of developmental pressures being felt by the landowner, and the kinds of amenities he would like to conserve on his property. The third section of the survey included questions about the landowner’s personal knowledge of easements and two stated choice questions regarding conservation easements. These stated choice questions focused on five attributes: contract length, managerial control, wildlife habitat, access and payment. The final section of the survey asked respondents about demographic characteristics. Data were analyzed as a multinomial logit random utility model in LIMDEP. Respondents preferred an easement that was in perpetuity over an easement that was term in length. Respondents were less likely to accept an easement if public access on their property was required. As payment proportion in relation to the respondents’ perception of the value of their land went up, so did the likelihood that they would accept the easement. Landowners in Colorado were more likely to accept an easement than landowners in Wyoming. This is somewhat expected as developmental pressures in Colorado are higher than Wyoming, and thus far more easements have been transacted in Colorado than in Wyoming. Years on the land and connection to community were significant in explaining the acceptance of an easement scenario. The more connected one was to their community, the more likely they were to accept an easement. The longer a respondent had lived on their land, the more likely they were to accept an easement as well. The level of education a respondent had achieved negatively impacted easement acceptance. If an easement was already in place on a respondents’ property, the likelihood of accepting an easement scenario increased significantly.Land Economics/Use,

THE CONTRIBUTION OF ENVIRONMENTAL AMENITIES TO AGRICULTURAL LAND VALUES: HEDONIC MODELLING USING GEOGRAPHIC INFORMATION SYSTEMS DATA

Geographic Information Systems (GIS) data are used in a hedonic model to measure the impact of recreational and scenic amenities on agricultural land values. Results indicate agricultural land values are determined by environmental amenities as well as production attributes. Significant amenity variables included scenic view, elk habitat and fishery productivity.Environmental Economics and Policy, Land Economics/Use,

The host galaxies of three radio-loud quasars: 3C 48, 3C 345, and B2 1425+267

Observations with the Wide-Field/Planetary Camera-2 of the Hubble Space Telescope (HST) are presented for three radio-loud quasars: 3C 48 (z=0.367), B2 1425+267 (z=0.366), and 3C 345 (z=0.594). All three quasars have luminous (~4 L^*) galaxies as hosts, which are either elliptical (B2 1425+267 and 3C 345) or interacting (3C 48), and all hosts are 0.5 - 1.0 mag bluer in (V-I) than other galaxies with the same overall morphology at similar redshifts to the quasars. The host of 3C 48 has many H II regions and a very extended tidal tail. All nine of the radio-loud quasars studied here and in Bahcall et al. (1997) either have bright elliptical hosts or occur in interacting systems. There is a robust correlation between the radio emission of the quasar and the luminosity of host galaxy; the radio-loud quasars reside in galaxies that are on average about 1 mag brighter than hosts of the radio-quiet quasars.Comment: Accepted for publication in ApJ. 3 postscript and 3 jpeg figures.

Cognitive behaviour therapy versus counselling intervention for anxiety in young people with high-functioning autism spectrum disorders: a pilot randomised controlled trial

The use of cognitive-behavioural therapy (CBT) as a treatment for children and adolescents with autism spectrum disorder (ASD) has been explored in a number of trials. Whilst CBT appears superior to no treatment or treatment as usual, few studies have assessed CBT against a control group receiving an alternative therapy. Our randomised controlled trial compared use of CBT against person-centred counselling for anxiety in 36 young people with ASD, ages 12–18. Outcome measures included parent- teacher- and self-reports of anxiety and social disability. Whilst each therapy produced improvements inparticipants, neither therapy was superior to the other to a significant degree on any measure. This is consistent with findings for adults
