The Evolution of an Ecosystem Approach: the Diamond Schematic and an Adaptive Methodology for Ecosystem Sustainability and Health Ecology and Society
Waltner-Toews, David; University of Guelph; dwaltner@uoguelph.ca; Kay, James; ;.
Over the past 15 yr, an international network of researchers has developed and tested a methodology for integrating complex systems theories into sustainable development projects. Drawing on our best theoretical understanding of complex systems and combining it with best practices of community engagement drawn from a wide variety of sources, we have developed a methodology that is theoretically sound and practically effective. AMESH, an Adaptive Methodology for Ecosystem Sustainability and Health, has emerged from, and been tested in, Nepal, Kenya, Canada, and Peru.

Stated Choice Experiments with Complex Ecosystem Changes: The Effect of Information Formats on Estimated Variances and Choice Parameters AgEcon
Hoehn, John P.; Lupi, Frank; Kaplowitz, Michael D..
Stated choice experiments about ecosystem changes involve complex information. This study examines whether the format in which ecosystem information is presented to respondents affects stated choice outcomes. Our analysis develops a utility-maximizing model to describe respondent behavior. The model shows how alternative questionnaire formats alter respondents’ use of filtering heuristics and result in differences in preference estimates. Empirical results from a large-scale stated choice experiment confirm that different format presentations of the same information lead to different preference parameter estimates and error variances. A tabular format results in choice parameter estimates with statistically smaller variances than parameters estimated from...
