community liaison refers to the systems and processes used to exchange information between national authorities, mine-action organisations and communities on the presence of mines, unexploded ordnance and abandoned munitions. it enables communities to be informed about planned demining activities, the nature and duration of the tasks, and the exact locations of marked or cleared areas. furthermore, it enables communities to inform local authorities and mine-action organizations about the location, extent and impact of contaminated areas. this information can greatly assist the planning of related activities, such as technical surveys, marking and clearance operations, and survivor-assistance services. community liaison ensures that mine-action projects address community needs and priorities. community liaison should be carried out by all organizations conducting mine-action operations.
