One of the key things is to ensure that in the budgets of the United Nations monitoring mechanisms there is enough funding for child- and gender-related expertise, and that this funding, particularly in places like South Sudan, leads to proper investigations with proper compiling of evidence and data so that prosecution can be pursued.
Without that, you're basically hooped, unless you have people investigating. As Kevin says, the voice of the child and the woman is extremely important, so you need to have people trained to deal with how to speak to the children so that we don't further traumatize children. That requires special training. That requires funding, and people to be dispatched to the field to do that. You need child protection officers and child protection advisers, and you need the budget to support them.
