The aim of this review is to consolidate and enhance the evidence base on the prevention of, and response to, public sexual harassment and other forms of gender-based harassment in all public spaces, to understand prevalence, causes and effective interventions. It will directly inform the priority of the Blueprint work stream: Gender-based Harassment in all Public Spaces. The Blueprint approach has been adopted by Welsh Government and Policing in Wales to support delivery against the Wales Violence Against Women, Domestic Abuse and Sexual Violence (VAWDASV) strategy.
