Human trafficking is a crime that creates alarming figures for the international system. It is the second largest crime in the world and moves around 150 billion dollars of profits for criminals by the year. It is a practice that subjects more than 800 million victims every year, it is also a serious human rights violation. There are global and governmental public policies that think and creates strategies to the fights against human trafficking as well as international regimes and organizations that aim the same objective. That said, the inability to face the crime in an effective way is at least unsettling to researchers and public servers. This dissertation aims the reflection about the main reasons that justifies the existence of the crime. Even though there are public policies to fight it for almost a century, it identifies that among the countless methodological challenges, the inability to monitor the crime at a global level presents greater risk of hindering the implementation of these strategies in all its spheres, whether they are: awareness, investigation or criminalization. The inability to solve the problem itself creates restlessness and a desire for a change. In this line of thought, the research proposes a dialogue with the main actors in the agenda of fight against contemporary human trafficking to try to align speeches and identify similar difficulties to think about possible alternatives to this unfolded challenge.
