The Geneva International Centre for Humanitarian Demining conducted a study in early 2012 to consider the effectiveness of performing external post-clearance inspections. GICHD took into account the practices of the International Mine Action Standards, the International Organization for Standardization and the numerous mine action programs worldwide. It also worked with the Swedish company Preference Consulting to determine the mathematical probability of finding a mine/explosive remnant of war during external post-clearance inspections. Lastly, GICHD examined the normative effect of external post-clearance inspections as well as the financial cost associated with their execution.
