Abstract We develop a Perl script to administer an experimental WWW survey (http://bluehen.ags.udel.edu/survey) analyzing public preferences for farmland protection. The survey first explains a public purchase-of-development-rights (PDR) program under which farmland owners may bid to sell their development rights to a state farmland preservation board. Sellers retain possession of their land, but it can never be developed. Survey respondents evaluate five hypothetical offers to sell development rights, as if they were serving on the farmland preservation board. Each respondent makes a series of pairwise choices between farms, portrayed both graphically and verbally. Each mouse click on the image of a preferred farm is trapped by a CGI function in the script and passed to an insertion sort algorithm which determines the next logical comparison pair and displays it using standard HTML table formatting. The script determines a complete preference order for the five farms from 6-8 pairwise comparisons, then elicits a final numerical rating for each farm in the preference order, and e-mails the responses to the authors.
The survey is based on an orthogonal experimental design consisting of 25 farms described by nine attributes: total acreage, percent forest, farm type, adjacency to other protected farmland, road frontage lost to development, farm income, local development pressure, long-term viability of agriculture, and the owner's offer price for the development rights. A statistical analysis of preliminary response data yields plausible preference weights for the farm attributes, demonstrating the technical feasibility of this survey technique.
