Tourism & the Triple Bottom Line

"After several decades conducting and directing research about the social, environmental, and economic impacts of tourism on destination communities, I have concluded that the tourism engine is greatly underutilized.  I firmly believe the tourism industry can be a powerful force for enhancing the triple bottom line."

Research History

Most of Dr. Tyrrell’s work over the past thirty years has been to determine the economic impact of tourism on various communities.  However, almost every economic research project has revealed environmental, social and economic issues beyond the scope of the research that were of much greater importance .  A broad, transdisciplinary approach to the dynamics of community development and the role of tourism in this development is clearly needed.
