In the present report, submitted pursuant to General Assembly resolution 76/147, the Special Rapporteur on the sale and sexual exploitation of children, including child prostitution, child pornography and other child sexual abuse material, Mama Fatima Singhateh, describes the activities undertaken in relation to the discharge of her mandate since her previous report to the Assembly (A/76/144). She also presents a thematic study on addressing the vulnerabilities of children to sale and sexual exploitation within the framework of the Sustainable Development Goals. The study includes identification of children who are at risk or vulnerable to sale and sexual abuse and exploitation under targets 5.3, 8.7 and 16.2. The Special Rapporteur also suggests measures for the protection of vulnerable groups of children within: (a) the situational status of the family; (b) the digital space; (c) institutional and alternative care. Good practices and recommendations are underscored through references to national efforts towards ensuring that no child is left behind.
