Using Choice Modeling to estimate the effects of environmental improvements on local development: When the purpose modifies the tool

A Choice Modeling (CM) study was chosen to assess specific management actions related to bird-watching on the Portuguese island of Terceira in the Azores. The usual willingness-to-pay measure was replaced by the willingness-to-stay (WTS) longer on the island for bird-watching, given changes in the site attributes. Results of the valuation study were presented to stakeholders and policy-makers using an innovative method. In particular, CM results were incorporated into a modeling tool which simulated the impact of alternative policy packages. For each selected scenario, users were able to understand birdersʹ WTS and its impact on the local economy. The tool provided a fast and clear way of communicating relevant information, resulting in a more informed and inclusive deliberative process. Furthermore, we were able to see how results were used by the final users and came to the conclusion that local managers had preconceived ideas which did not match birdersʹ preferences. This work led to a shift regarding prior beliefs about the relevance of bird-watching activities on the local economy as well as management actions likely to promote it. The underlying participatory approach was found to be an essential feature for the success of this science and policy interaction.
