How can sustainable peace be achieved? The book identifies potential supranational, state and non-state actors involved in peacebuilding processes. Further - more, it develops strategies to address the problems and dilemmas of international peacebuilding. An important contribution to a highly topical debate. Hopes for a less conflict-prone world after the end of the Cold War were bitterly disappointed. Instead, the international community is faced with protracted wars and violent conflicts today. In addition, social, economic and cultural insecurities as well as fragile statehood challenge the post-Westphalian environment. As a result, scholars and policy-makers alike are trying to develop viable strategies for sustainable peace. The book contributes to this debate, as it illustrates current research results on the topic and addresses the complex problems and dilemmas that various international peace - building actors are confronted with.
