The number of girls that are being exploited for prostitution in Nepal has increased in recent years, and girls suffer a high risk of being exposed when they come from already poorly conditions. Previously, uneducated girls could be found in the adult entertainment sector, but nowadays even educated girls are being exploited. This thesis aims to gain further understanding to why girls are being exposed and why it is difficult to protect them. By conducting qualitive interviews with employees from several NGOs working to protect girls from being exploited for prostitution, insights has been given about socio-structural factors that influences the situation for girls. By examining these factors with support from theoretical approaches that highlights social injustice, gender discrimination and structural oppression this thesis presents how different factors affect the work of protecting girls, and how the same factors also are contributing to why girls get exposed. The state of Nepal shows several efforts in trying to eradicate the problem and have ratified both the Convention on the Rights of the Child and the Optional Protocol to the Convention on the Rights of the Child on the sale of children, child prostitution and child pornography. The state has also made changes in national law that shall promote and strengthen children's rights. Although the laws are strong, the protection for girls is insufficient and girls are vulnerable to being exploited by traffickers. The Government of Nepal, NGOs and several other authorities are working together to eradicate the problem, but the work needs be strengthened, coordinated and responsive to influencing factors simultaneously in order to achieve a long-term solution. This thesis suggest that cultural norms need to be challenged more and that the Government of Nepal needs to oversee how structural injustices affect opportunities for girls to take part of social benefits. In addition, knowledge about legal and moral rights needs to be increased among girls and in society as a whole, moreover the knowledge about trafficking and prostitution needs to be spread.
