As an increasing number of SCUBA divers impact coral reef
resources, managers
are faced with the need to take action to reduce or eliminate the problem. The
aim of this project is to help decision makers understand SCUBA diver
preferences for protecting coral resources, how divers decide between management
measures, and which combinations of management measures would have the most
overall support in the sport diver community.
The study’s objectives are to (1) identify realistic management measures for
protecting coral resources salient to SCUBA divers, (2) evaluate the relative
importance of each measure to divers, (3) estimate the importance of options for
each management measure, (4) estimate the aggregate importance of management
scenarios based on various combinations of the management measures, and (5)
examine the potential for using stated preference discrete choice models (SPDCMs) in
support of coral reef management and conservation in other MPAs.
We are studying SCUBA divers who utilize a variety of diving locations using a
stated preference discrete choice model. Traditional research designs for evaluating
management preferences ask respondents to indicate the extent to which they
prefer each individual management option. This can result in a lack of
understanding of the relative importance of one attribute to another and as a
result provides little insight to participants’ actual management preferences.
Stated preference discrete choice models are based on the assumption that complex
decisions are based not on one factor or criterion but on several factors
considered jointly and make use of hypothetical scenarios to derive recreationists’ preferences
This research project is being conducted using a community-based context. We
met with a group of stakeholders from the Flower Garden Banks National
Marine Sanctuary (FGBNMS) to better understand the potential SCUBA
diving impacts on coral resources and the various management alternatives
available for dealing with the impacts. From this, salient issues and management
attributes and levels were identified and an appropriate survey instrument
developed and pretested on divers.
Management of marine protected areas (MPAs) and coral reefs is moving toward a
new paradigm in which the greatest challenges faced involve the management of
people as well as resources. This will require a much greater understanding of
people, their use of MPA resources, and their support for various management
alternatives. An understanding of the relationship between people and MPAs is
essential for both protecting resources in an unimpaired state for future
generations and providing recreational opportunities for present generations.
This project is titled “Using Stated Preference Choice Experiments to Analyze
SCUBA Diver Preferences for Coral Reef Conservation” and has been funded by the
Coral Reef Management Program of the
National Fish and Wildlife Foundation in
Washington, D.C. with additional funding support from the Texas Agricultural
Experiment Station, Texas A&M University System.
The project began on January 1, 2004 and will conclude on December 31, 2004. Dr.
Robert B. Ditton (r-ditton@tamu.edu) is the Principal Investigator for this
project and Michael Sorice (m-sorice@tamu.edu) is the Research Assistant. Both
are affiliated with the Department of Wildlife and Fisheries Sciences at Texas
A&M University, College Station, TX. |
