Peace & Security

Despite the decline in interstate war over the past several decades, armed conflicts and organized violence remain major threats to people’s lives in most parts of the world. External actors are invested in these conflicts in many ways: through their economic footprint, by protecting specific interests, or by protecting people and building peace. In our interconnected world, there is no way we can avoid having influence. Our choices have consequences that either fuel the violence or help find ways out of war.

So how do we know what works? How can we act responsibly if we do not? While Rwanda and Bosnia have shown the catastrophic consequences of inaction, our instruments to act are often flawed. Mediation, capacity-building, support for political reform and the use of military force require constant learning and sometimes fundamental change.

In our work with partners around the world, GPPi focuses on knowledge, norms and organizations in the global politics of peace and security. Currently we address four themes: (1) conflict, intervention and peacebuilding, (2) the prevention of mass atrocities, (3) the role of rising powers, and (4) organizational learning and change.
