The purpose of this activity, implemented by UNIDIR in cooperation with UNLIREC, was to carry out the second regional training-of-trainers workshop on the ISACS Assessment Tool in Lima, Peru. By the end of the workshop, thirteen staff members from UNLIREC, the Organization of American States (OAS) and the UN Mine Action Service (UNMAS) Colombia were trained on how to use the ISACS Assessment Tool and how to train others in its use. The workshop focused on using the ISACS Assessment Tool to guide operational work on small arms control in the Latin American region in areas such physical security & stockpile management, marking & record keeping, and border controls & law enforcement cooperation.
