Posted Over recent years few countries have made significant progress toward sustaining peace. It is important to better understand what works and what does not in conflict-affected countries. Here I will present a summary of my research on peace-building efforts in Haiti throughout the period 2004-2015, as well as some additional considerations of the political crisis of 2016 and ongoing crises since. UN/MINUSTAH/Jesús Serrano Redondo, CC BY-SA 4.0 Can we avoid a conflict relapse? The answer is complex and, to a large extent, case sensitive. The research I carried out in Haiti focused on one methodological tool, the Post Conflict Needs Assessment (PCNA), which is, in many ways, a sort of Transitional Plan. The PCNA is usually led by World Bank and the United Nations, together with national and international counterparts. Since 2000 this methodology was developed in more than 15 countries, including Soudan, Somalia and Georgia. https://www.un.org/peacebuilding/policy-issues-and-partnerships/partnerships/un-worldbank-partnership The PCNA tool was applied to Haiti following the minor conflict outbreak in 2004. In retrospect, did it work?
