Africa

In Africa the colonial powers abolished slavery in the nineteenth and twentieth centuries. However, in areas outside their jurisdiction, such as the Mahdist empire in Sudan, the practice continued to thrive. Now, institutional slavery has been banned worldwide, but there are numerous reports of women sex slaves in areas without effective government control, such as Sudan,^[67] Liberia,^[68] Sierra Leone,^[69] northern Uganda,^[70] Congo,^[71] Niger^[72] and Mauritania.^[73] In Ghana, Togo, and Benin, a form of religious prostitution known as trokosi ("ritual servitude") forcibly keeps thousands of girls and women in traditional shrines as "wives of the gods", where priests perform the sexual function in place of the gods.^[74]

 

Asia

In January 2010, the supreme court of India stated that India is "becoming a hub" for largescale child prostitution rackets, and suggested the setting up of a special investigating agency to tackle the growing problem.^[75]
