After nearly 30 years of humanitarian mine action, Cambodia has a mature, efficient, and sophisticated Mine Action sector which applies a ‘top-down and bottom-up approach’ to ensure that clearance resources are directed to the most impacted communities and clearance itself addresses the needs and priorities of the affected communities. This is in line with the principle of ‘needs-driven, people-centered’. The following briefing paper aims to provide the reader with an understanding of the mine clearance planning and prioritization process that is being implemented by the mine action sector in Cambodia.
