We are now in a position to consider some of the possible new approaches which are showing promise and might contribute to a truly international programme for tackling the scourge of human violence. We have overviewed a range of biological, psychological, and social factors which play a role in causing violence, and knowledge gained from each of these perspectives can be drawn upon to devise interventions within the overall public health framework. As described in Chapter 1, this approach has encouraged and underpinned a growing global perspective on violence. Governments in virtually every country around the world have seen it as a core part of their role to establish national laws which maximise safety within their jurisdiction. Some richer countries have gone further and developed extensive national public health and clinical programmes to tackle the problem. Public policies at the national level are now seen as a key element of an effective prevention programme (D’Inverno et al., 2018), and instruments to convert these policies into effective programmes are increasingly available (Centers for Disease Control and Prevention, 2018). However, concerted and synchronised international action to deal with violence has appeared only in the past twenty years since the UN and its constituent body, the WHO, turned their attention to the problem.
