Multiple Impacts of Tourism Activity

This chart here taken from “Global Trends in Coastal Tourism” prepared by the Center for Eco-Tourism and Sustainable development shows in detail many of the most prominent effects of tourism on an area. Road development is not specifically mentioned but facilitates all of these by providing access to the tourist. The outcomes all tend to be negative such as “acid rain, or vandalism” and give the impression that tourism is essentially bad for everything in a region except for the economy.

Tourism Western Australia site suggests that road infrastructure is crucial to the spread of tourism beyond major gateways. According to a study done by Tourism Research Australia, driving holidays make up 77-93 percent of domestic overnight trips taken in Australia. Below is a tourism map that indicates the highways, major state roads, and other roads and tracks in Australia.

While many main roads already exist, Tourism Western Australia suggests an investment into road construction and improvements. Increased infrastructure has the potential to increase tourism; however, are consequences such as environmental impacts being taken into consideration?

Machu Picchu Railway


Since its discovery in the early 1900’s the ancient Inca site of Machu Picchu has been studied extensively by archaeologists and eventually has become one of Peru’ popular tourist destinations bringing in thousands of tourists from around the world each year. While the tourism industry surrounding Machu Picchu in Peru has been very successful and helped local economies, the environmental impacts of tourism in the area are unmistakable.  In 2008 Machu Picchu was listed among the top 100 most endangered sites due to environmental degradation. One of the sources of this environmental degradation has been the construction of a railway to bring tourists and their luggage into Machu Picchu. This has increased the number of people walking around the site and has led to serious environmental degradation of the area. This site compares some of the costs and benefits of the railway and the map above shows the path that the railway takes. Do you think that the construction of this railroad was a worthwhile Endeavour? Why or why not?

Cities of tomorrow

Check out the two links above. The first stresses the need for cities to grow upwards rather than out; the second provides a neat article about urban farming. While these links do not talk in depth about transportation and urban roads, implementing the changes put forth would have drastic effects. The need for roads would be greatly reduced without the need to ship food into cities and commuters would not need roads in order to get to work if they lived an worked in the same building.

Impacts of Development on Watershed Areas

This website, created by the Oregon Environmental Council, is designed to educate people about the impacts that development can have on local watersheds. It illustrates the impact that even a small, one family home can have on a local ecosystem. The construction of a single family home can create impervious surfaces on anywhere from 25 to 60% of the property. The amount of impervious surface needed to cause a significant amount of damage to an ecosystem is often less than 10%. This figure is only for a single family home. When we talk about the impact of urban developments that can have close to 100% impervious surface cover the damage to the ecosystem is unavoidable. It is important to realize the widespread effects that development can have on local watersheds and the surrounding ecosystems. Take a look at this website to look at some of the other ways that ecosystems can be damaged by urban development.

Do Parking Lots Cause More Traffic?

In an article by Slate Magazine, Tom Vanderbilt explores whether planning policies mandating a minimum number of parking spaces when building urban and semi-urban areas is really a good idea. These policies took hold around the 1960’s, meaning they do not factor in the other forms of transportation that have developed since then and the initiatives of environmentally people to utilize them. Creating large parking lots fragments urban areas and makes walking unpleasant or impractical, which in turn leads to more people driving and then can lead to the need for more parking lots.

Some cities have already begun reducing the number of policy mandated parking spots, such as in Columbus, Ohio where they have reduced parking minimums for malls by 20%.

Structural Organization of Urban Areas Affects Public Transport

I found a study conducted in Milan, Italy that concluded the nature of urban expansion influences the degree of urban mobility and the competitiveness of public transportation. Urban sprawl, which results in more dispersed and less structured development, represents one of the least environmentally acceptable solutions in the study and is associated with the lowest level of public transport. A link to the study is provided at the bottom of the page. A NASA webpage that examines the impacts of fast growing urban areas provides a useful connection between the study that I found and the spatial extent of the environmental impacts of urban sprawl. There is a neat reconstruction of the growth of Baltimore over the past 200 years. Enjoy!

Urban Mobility and Urban Form

Across Europe, Irking Drivers is Urban Policy

As the city of Zurich has made harder for people to drive cars into the city, it has also improved public transport, with an elaborate and ever expanding system of trams.

According to “Across Europe, Irking Drivers is Urban Policy,” an article found in the New York Times, a car takes up about 4,000 cubic feet of urban space in Zurich while a person only takes up 3. Large cities in the United States have the tendency to alter their cities to accommodate driving; however European cities such as Zurich Vienna, Munich, and Copenhagen have been taking steps to make cities more livable for people. The idea is simple: to create environments that are openly hostile to cars thus forcing people to use more environmentally friendly forms of transportation. In Zurich measures such as adding closely spaced red lights on roads to create delays, removing pedestrian underpasses, and banning cars on some blocks are being taken. Results have shown that these methods are proving to be effective. Households without cars have increased from 40 percent to 45 percent and car owners are using their cars less. US cities such as San Francisco and New York are slowly taking similar action, but are still lacking fundamental support and policy. I leave you with the following statement made by a city official, “I feel like I am always waiting to cross the street. I can’t get used to the idea that I am worth less than a car.”

Global Health Map

Linked is a site with a detailed Healthmap. This map represents all of the current notable disease activity throughout the globe and the level of activity at this area. A casual glance at this map shows that there is a definite correlation between developed areas (i.e; east coast of USA, Middle Europe) and the frequency of disease outbreak. This could be attributed to population mobility and/or density which are both products of developed areas. Oppositely, the more severe outbreaks occur in more secluded areas such as mid-west Africa and western Brazil. This may be an indicator of how much access these areas have to pharmaceuticals.
