In particular, it is important to build socio-cultural and political support for women's participation within security system institutions amongst the general public and within particular institutions such as the police and the armed forces. This can be done through education, training and awareness-raising as well as promoting women role models. Increasing the balance of women and men at all levels of an institution increases operational effectiveness and ensures diversity of opinions and approaches, however, male and female personnel with gender expertise are still necessary to ensure the full integration of gender issues. Preventing and adequately responding to these violations will improve the work environment, increase public trust and enhance the accessibility and delivery of security and justice services. Gender-responsive codes of conduct, sexual harassment policies and/or policies on sexual exploitation and abuse are essential.
