UNESCO and UN Women’s handbook on tackling violence against women and girls in sport is a practical toolkit for policy makers and sports practitioners looking to grasp the scale of this human rights violation and the tools to tackle it effectively. It is the first policy toolkit to consolidate and analyze a wide range of sources to map out the risks, opportunities, governance structures, legal and institutional sport frameworks, as well as the progress made in and around the sport ecosystem to address gender-based violence. It provides much-needed policy guidance by sharing data, impactful testimonies, case studies and detailed recommendations for different key stakeholder groups, including on the design of preventive strategies, regulations, incentives and sanctions to address violence against women and girls in sport. Policy makers and sport practitioners around the world are encouraged to join the movement to tackle and upend this violence by picking up these recommendations and rolling them out in countries and communities around the world.
