Lessons learnt from the Global reports of the Scelles Foundation. Every 2 years the Scelles Foundation publishes geographic and thematics researchs on sexual trafficking and prostitution around the globe. This white paper summarizes the risks of growing criminality, the violence supported by the victims, and the lack of political will to address this issue at the right scale. The international context in which this criminal business expands makes the challenge even more difficult. We call for a global mobilisation of public and private actors.
