For the most part, the article is exactly what you would expect. I am not that it is a bad article or that this is not a significant news story, just that the situation (indigenous and local peoples suffering by shortsighted pursuit of the economic success of governments and international businesses) is one that has played out in this exact way many times before. The article does mention one really interesting thing at the end though that I thing holds the solution:
There is a “legitimate concern that Cusco’s travel infrastructure is at its limit,” says Mark Rice, the author of Making Machu Picchu: The Politics of Tourism in Twentieth-Century Peru. But the location of the new airport will do a “lot of damage to one of the key tourism offerings of Cusco, which is its scenic beauty”.
The problem is that Machu Picchu is “so singularly dominant for the Peruvian tourism offering”, he says. “The best way I can describe it is if people going to Britain only went to Stonehenge.”
It is never a good idea to base an economy on a single industry or to base an industry on a single product (citation). I think that a better move for Peru would be expanding its entertainment industry, especially music. Non-english songs have received a lot of success in America, so the language barrier is not as much a deterrent as it used to be. Many anime dubs still use the same openings as the original. Building venues for large performances can be a huge return on investment, diversifies the economy, and enhances local culture rather than destroy it.
