Women’s sex work migration and human trafficking are seen as severe manifestations of global gender inequality and has received mounting international attention. Simultaneously, women constitute more than half of the worlds’ migrants and contribute significantly to the development of their poor home countries and communities. The project explores these forms of migration and their relation to the EU’s increasingly restrictive migration policies seen from the perspective of the Global South. The project analyses two flows of migration over time: Thai women’s sex work and marriage migration and Nigerian women’s irregular migration to the European sex industry. The research project stimulates theoretical rethinking within migration studies by creating a dynamic approach, which combines social transformations and migration restrictions in a gender perspective. Additionally, migrant societies’ perspective on sex work migration and human trafficking over time will be investigated.
