http://www.montrealcampus.ca/la-misere-des-riches: Recently an article on Slum tourism appeared in French on the website of Montrealcampus, mainly regarding the ethical aspects of the subject.
Left at the Crossroads: Ogling the poor: Slum tourism was also the subject of a column by Marc Saint-Upéry, discussing the ethics of slum tourism and linking favela tourism to tourism in Victorian times.
Towship tourism: A mixed blessing: Not so much an article on township tourism, but a photographical slideshow that depicts the concept of township toursin South Africa fairly well.
