As part of the UN's new strategy to combat sexual exploitation and abuse, this issue is for the first time being acknowledged as a system-wide one, which requires a common approach. Therefore, as part of his strategy, the Secretary-General has asked Agencies, Funds and Programmes to adopt new measures and strengthen existing ones to better prevent, detect, report and take action against personnel, who commit these inexcusable and abhorrent acts. The vast majority of staff from UN Agencies, Funds and Programmes are deployed worldwide, often in extremely dangerous environments and facing hardship themselves, to help vulnerable populations and provide humanitarian assistance, promote human rights and help countries advance towards sustainable peace and development.
