Conceptual Approach work. Accordingly, the purpose of tertiary prevention is to hinder the re-emergence of tensions and the recurrence of violence. To be successful, conflict resolution efforts should ideally be based on local strategies and initiatives that take place within existing political systems and societal practices. In line with the UN’s sustaining peace agenda2, the CPC’s tiered approach to conflict prevention emphasizes the need to be holistic, cross-cutting, and implemented throughout the conflict cycle. Sustainable peace and transition, therefore, relate to a wide and diversified set of measures targeted at reducing the risk of relapse into violent conflict. Building sustainable peace includes, most importantly, the strengthening of local capacities and institutions at all levels to address root causes of instability, as well as the promotion of open, diverse, and tolerant societies that are resilient to violent crises and conflicts. The OSCE works toward these goals by providing participating States with advice and practical support for societal, political, and legislative reforms, including by strengthening the functionality, transparency, and accountability of democratic institutions in line with good governance and the rule of law. In 2011, the OSCE decided through Ministerial Council Decision No. 3/11 that “post-conflict rehabilitation and peacebuilding must involve efforts to address violations of human rights and fundamental freedoms, intolerance and discrimination, and the absence of strong democratic institutions and the rule of law”.3 2  UN (2017). 3  OSCE (2011a). 14
