Trafficking in human beings is modern-day slavery, involving victims who are forced, defrauded or coerced into labour or sexual exploitation. Those involved in the illegal trade conduct it in such a seemingly decent manner and ease that their victims do not suspect any foul play. Although it is a complex form of an organized crime involving well-structured criminal groups, trafficking is usually perceived by traffickers as low-risk and promising high returns. Two main types of trafficking exist in the sub-region: trafficking in children mainly for domestic work and for farm labour across and within national borders; and trafficking in women and children for sexual exploitation mainly outside of the sub-region. Where is this seemingly limitless supply of trafficking victims coming from, and what factors contribute to sustaining this supply? The objectives of this monograph are within the framework of the aim of sustaining and increasing the possibility of fighting against the phenomenon of human trafficking in Nigeria. It is an outcome of research work on menace of human trafficking in Nigeria.
