If I could have one wish granted, it might well be a total end to rape. That means a significant weapon of war gone from the arsenal of conflict, the absence of a daily risk assessment for girls and women in public and private spaces, the removal of a violent assertion of power, and a far-reaching shift for our societies.

Rape isn’t an isolated brief act. It damages flesh and reverberates in memory. It can have life-changing, unchosen results — a pregnancy or a transmitted disease. Its long-lasting, devastating effects reach others: family, friends, partners and colleagues.

In both conflict and in peace it shapes women’s decisions to move from communities through fear of attack or the stigma for survivors. Women and girls fleeing their homes as refugees also risk unsafe transport and insecure living conditions that can lack locked doors, adequate lighting, and proper sanitation facilities. Girls married as children in search of increased security at home or in refugee camps can get caught up in legitimised conditions of rape, with little recourse for those wishing to escape, such as shelter and safe accommodation.

In the vast majority of countries, adolescent girls are most at risk of sexual violence from a current or former husband, partner, or boyfriend. As we know from our work on other forms of violence, home is not a safe place for millions of women and girls.

Almost universally, most perpetrators of rape go unreported or unpunished. For women to report in the first place requires a great deal of resilience to relive the attack, a certain amount of knowledge of where to go, and a degree of confidence in the responsiveness of the services sought — if indeed there are services available to go to. In many countries, women know that they are overwhelmingly more likely to be blamed than believed when they report sexual assault, and they have to cope with an unwarranted sense of shame. The result of these aspects is a stifling of women’s voices around rape, significant under-reporting, and continuing impunity for perpetrators.

Research shows that only a small fraction of adolescent girls who experience forced sex seek professional help. And less than 10 per cent of women who did seek help after experiencing violence contacted the police.

One positive step to increase accountability is to make rape universally illegal. Currently more than half of all countries do not yet have laws that explicitly criminalise marital rape or that are based on the principle of consent. Along with criminalising rape, we need to get much, much better at putting the victim at the centre of response and holding rapists to account. This means strengthening the capacity of law-enforcement officials to investigate these crimes and supporting survivors through the criminal justice process, with access to legal aid, police, and justice services, as well as health and social services, especially for women who are most marginalised.

Having more women in police forces and training them adequately is a crucial first step in ensuring that survivors begin to trust again and feel that their complaint is being taken seriously at every stage of what can be a complex process. Progress also requires that we successfully tackle the many institutional and structural barriers, patriarchal systems, and negative stereotyping around gender that exist in security, police, and judicial institutions, as they do in other institutions.

Those who use rape as a weapon know just how powerfully it traumatises and how it suppresses voice and agency. This is an intolerable cost to society. No future generation must struggle to cope with a legacy of violation.
