Sport mega-events, such as the Olympic Games or World Football Cups, are publicly broadcasted via various media channels and receive high amounts of attention worldwide. Such sport mega-events are also accompanied by far-reaching consequences for the different populations located in host cities. In his ARC-GS lecture, Professor Philip Hubbard (Professor of Urban Studies at King's College, London) explained how the urban sex work market, and those involved in it, are shaped and affected by changes that occurred in the context of the World Football Cup, which took place in Rio de Janeiro in 2014, and the subsequent Olympics of 2016. How did these sport mega-events and their related urban policies impact individuals within in the sex sector? Which changes did those individuals encounter, and how were their work practices affected? Which strategies did they develop to deal with and navigate the new legal regulations? Hubbard and his colleagues engaged in extensive fieldwork to analyse the impact of the World Football Cup and Olympics on the sex work sector and the agency of individuals located in that field. The research included interviews, document analysis and observational data, among other methods.
