An encampment is a site where an individual or group sets up temporary accommodation, consisting of physical structures (i.e. tents, huts, shelters built with found materials). Circumstances dictating their formation include military operations, or refuge from environmental disaster or political persecution (see Emmelhainz in SDUK09). A lack of affordable housing and limited shelter capacity in many cities has increased encampment occupancy. These communities are frequently confronted by law enforcement, who forcibly displace occupants. Anti-displacement and mutual aid organizers mobilize communities in support of accessible housing and policy change (see Xiang in SDUK09).
