This publication is a joint UN-HABITAT and UNDP effort to investigate access to basic urban services in the Adjacent Areas (AAs) of Palestinian Refugee Camps in Lebanon. AAs are informal Palestinian gatherings that are located along the boundaries of official Palestinian refugee camps in Lebanon. In terms of access to basic urban services, AAs represent "Grey Areas" since they are denied both public and UNRWA basic urban services, given that the latter are provided within the boundaries of the official camps only.
