Since the mid-1990s the development community has focused significant attention on the potential and actual impact of development interventions on conflict resolution and peacebuilding in conflict-ridden and post-conflict zones. This has included the formulation and deployment of diverse concepts and tools of conflict sensitivity, including Peace and Conflict Impact Assessment (PCIA). Over the last 15 years the intent and application of PCIA has varied across the world. Mindful of this diversity, this article draws lessons from the application of PCIA in Pakistan, arguing that context-specific lessons are required to inform and shape the next phase of PCIA’s development and application, thus ensuring that it is increasingly beneficial to all stakeholders.
