It sounds to me as though you may be taking on too broad a subject. You might be able to write a much more effective report if you limited your research to one form of human trafficking. This would also make your review of the literature much easier to handle. Otherwise you might get so involved in identifying the different forms of human trafficking that you wouldn't be able to discuss any one of them in significant depth. You probably have an interest in one particular form of human trafficking, and you might learn more and contribute more by limiting your topic to that problem.
