What is Overtourism and What Can We Do About It?
Part IV

I concluded the last part by proposing a tentative definition of what Overtourism is, and now I will turn to presenting a starting point to addressing it. In this Part, and the concluding Part, I will cite some literature, most of it accessible, but written in English. Few people write about management of visitation and tourism in protected areas, so nearly all of what I cite is my own work and that of close colleagues. I invite others to add to this work in responses to these essays.

To address Overtourism, a number of things are needed. We need a set of principles which underlie planning and management actions, and we need a framework to help us build our situational awareness and help apply critical thinking skills (see for example Of course, we will also need to reflect upon our own mental models of the situation and recognize that we can benefit from complexity thinking ( We need to plan more holistically, as Jon Kohl and I noted in the Future has Other Plans.
Text Box: Table 1. Principles to guide visitor and tourism management in protected areas.
Principle 1. Appropriate management requires explicitly stated objectives.
Principle 2. Diversity of social, biophysical and managerial conditions in and among protected areas is inevitable and may be desireable.
Principle 3. Management is directed toward influencing human-induced change.
Principle 4. Impacts on biophysical and social conditions are inevitable consequences of human use.
Principle 5. Impacts can be temporally or spatially discontinuous.
Principle 6. Many variables impact the use/impact relationship.
Principle 7. Many management problems are not use density dependent.
Principle 8. Limiting use is only one of many management options.
Principle 9. Monitoring is essential to professional management.
Principle 10. The decision-making process separates technical decisions from value judgments
Principle 11. Consensus among affected groups about proposed actions is needed for successful implementation.

Today, I am going focus on principles and frameworks, but this will be very brief. For about 30 years, I have operating on a number of visitor management “principles” (they are probably more like insights than princples, but principles sounds better!). They have been derived from research and professional experience with visitor management, and they have been written in such a way as to cross types of protected areas, marine, terrestrial, cultural, natural, local parks as well as World Heritage Sites. These 11 principles are stated in Table 1. I will only discuss one of them, but you can read short summaries here (

I will not say much more about these principles here, but would like to demonstrate Principle 4, impacts are inevitable consequences of visitor use. Research on the use/impact relationship by such scientists as David Cole, Yu-Fai Leung and Jeff Marion (see for example, shows that a little bit of initial use leads to a disproportionae amount of impact the relationship looks like this, schematically with use level on the X axis and impact on the Y axis

The nature of this relationship means that where we already experience high levels of use, we will have high levels of impacts, and reducing use (and only use) will have little impact. This is true in both the biophysical and social domains. For example, the visitation at Yellowstone National Park is currently over 4 million visits per year, way to the right side of this graphic. It has a certain infrastructure that will not change even if use drops to 2 million or less visitors. The impacts of past decisions are here to stay, absent some major systemic level decision.

The graph also shows that focus of decisions ought to be ( and I respectfully suggest this) on the Y axis, the amount of impact that is acceptable. Since the curve that is in the graph is an average, there is variability around it. That variability means that factors other than use level influence impact, things such as visitor behavior, type of use, season of use, soils, visitor expectations and motivations and so on. For example on my recent family visit to Yellowstone. I knew visitation would be high, so my expectation were more in terms of family togetherness and learning, and viewing landscapes, and lots of bison than having the park to myself.

This graph also means that spreading use more evenly, sometimes advocated by protected area managers and academics is probably not the best strategy for minimizing impacts.
Finally, in this brief essay, we can think where we set the standard, at what point on the Y axis and how we make the decision and how that decision is made. Important questions about the role of science and public engagement.

Lets turn to frameworks for managing visitation and providing opportunities for quality visitor experiences. There are several, including but not limited to the Recreation Opportunity Spectrum, Limits of Acceptable Change, Visitor Experience and Resource Protection, Tourism Optimization and Management Model. They were mainly developed to respond to a carrying capacity approach which has failed both in theory and practice (for a short overview, see Each of these are described here, which was originally written for American protected area managers, so the first couple of chapters may not be that informative for many ( Warning, this last document is more of a book than a short article.

Recently, the federal land management agencies in the U.S. have put together an Interagency Visitor Use Management Process, which was the subject of two TAPAS sponsored webinars. I think this would also be a good starting point for discussions about what we can do about overtourism, although again, several of the components are related only to U.S. policy and law. Read about it here:

An important note: the frameworks here are not answers or solutions. What they do is help guide us through the critical thinking needed to address the challenges of managing visitors in protected areas. They are process oriented. Those who apply them use their own special knowledge of a local protected area and apply that in the frameworks.
