Modelling species distribution and abundance is important for many conservation applications, but it is typically performed using relatively coarse-scale environmental variables such as the area of broad land-cover types. Fine-scale environmental data capturing the most biologically relevant variables have the potential to improve these models. For example, field studies have demonstrated the i...

100 words max): This article estimates the impact of the 2007-2008 residential housing market bust on farmland values, using parcel-level farmland sales data from 2001-2010 for a 50-county region under urbanization pressure in western Ohio. Hedonic model estimates reveal that farmland was not immune to the residential housing bust; the portion of farmland value attributable to proximity to urba...

There is a growing awareness that farmland provides a host of nonmarket services, or amenities. Amenities are external benefits of farmland, i.e., beyond commodity production revenues, accruing to all types of residents (or “amenity consumers”) in rural, suburban, and urban areas. Farmland amenities may include aesthetically pleasing views, habitat provision, groundwater recharge, and a lack of...

Using plastic mulching for farmland is booming around the world. Despite its benefit of protecting crops from unfavorable conditions and increasing crop yield, the massive use of the plastic-mulching technique causes many environmental problems. Therefore, timely and effective mapping of plastic-mulched farmland (PMF) is of great interest to policy-makers to leverage the trade-off between econo...

The research question for this study is estimating the public’s willingness to pay for the public goods generated by farmland, and exploring respondents’ heterogeneity in their preferences for these goods. The approach used is a choice experiment, using respondents from the city of Wuhan, China. Six attributes representing public good values (farmland area, farmland fertility, water quality, ai...

Highway construction has accelerated urban growth and induced direct and indirect changes to land use. Although many studies have analyzed the relationship between highway construction and local development, relatively less attention has been paid to clarifying the various impacts of highways associated with farmland loss. This paper integrates GIS spatial analysis, remote sensing, buffer analy...
