In my last post, I claimed that only a small number of studies have been done on valuating eco-tourism as an ecosystem service. I was wrong. After some more digging around, I’ve discovered that a fair number of studies address this topic, though only a small number of studies actually evaluate specific regions of the world. One of the most interesting reports I stumbled upon was from the Journal of Environmental Management. In 1998, Susan Menkhaus and Douglas Lober, two researchers from Duke University, published a paper that focused on Costa Rican rainforests and their ecotourism value. If you’d like to read the whole thing, it’s titled “International Ecotourism and the Valuation of Tropical Rainforests in Costa Rica.”

Rainforests provide dozens of ecosystem services. In Costa Rica, they serve the booming eco-tourism industry.

By way of background, Costa Rica is a textbook example of effective management of natural resources, tourism, and integrated public policy. It is widely recognized as the greenest country in the world, and it remains the most visited Central American country. Covering less than 0.05% of Earth’s landmass, Costa Rica contains a whopping 5% of the world’s biodiversity, has 12 different life zones, and boasts one of the highest land protection rates in the world. Nearly half of the tourists that come to Costa Rica engage in some sort of eco-tourism activities. Needless to say, Costa Rica is the best nation to take as an example for this study, which attempts to quantify the value of Costa Rica’s rainforests from a tourism standpoint. Keep in mind, however, that the authors only sought to calculate the eco-tourism value of the rainforests—not anything else related to the forests’ medicinal, timber, or biodiversity value.

A good friend of mine has been working on developing a curriculum for sustainability lessons in Utica, and she asked me just a couple days ago for some help with the topic of ecosystem services. I thought it strange that she came to me (a hotelie, no less) for help on such a scientific topic, and I had to admit to her that my knowledge of the topic was shallow. Nonetheless, I pointed her to the UN’s 2005 Millennium Ecosystem Assessment (MA), the four-year study that is considered by the environmentalist community as the go-to resource on ecosystem services. I had skimmed the hefty 155-page synthesis report a few months earlier—I’d only initially did it because Eric Ricaurte, my research adviser, had recommended it to me—and I didn’t remember much from it. So after recommending the MA, I decided to read through some sections of it again.

Mangroves are a recognized source of ecosystem services. They buffer against storms, prevent erosion, and filter out toxins.

By way of background, ecosystem services are resources and processes that the natural environment provides for us. For example, trees provide oxygen for us to breathe, fish in the ocean serve as food, and earthworms help decompose our waste. But what caught my eye immediately from the Millennium Ecosystem Assessment was how it recognized ecotourism and recreation as important ecosystem services for humans. I couldn’t help but smile: while attempting to preserve their surrounding environments, eco-resorts around the world are also drawing upon this valuable ecosystem service by deriving revenue from it.
