Measuring change in place values using public participation GIS (PPGIS)

Place values, like human values, are hypothesized to be relatively stable and slow to change over time. In 2004, we conducted a baseline study of place values, called landscape values, with residents of Kangaroo Island (KI), South Australia, using public participation GIS (PPGIS). In 2010, we implemented an internet-based PPGIS monitoring study with the same households to measure changes in the importance and spatial distribution of landscape values. The empirical results indicate general stability in values both in importance and spatial distribution. But the results also suggest that land-use changes such as those resulting from human development will significantly influence the distribution of landscape values. Additional research is needed to advance understanding of landscape values for identifying land-use compatibilities and conflict, and managing public lands in a manner consistent with public values
