The area likely to be affected by a proposed project, including its ancillary aspects, such as power transmission corridors, pipelines, canals, tunnels, relocation and access roads, borrow and disposal areas, and construction camps, as well as by unplanned developments induced by the project, such as spontaneous settlement, logging, or shifting agriculture along access roads. For a larger and more complex infrastructure project, this area of influence may include people, land, and bodies of water that are in proximity to or even far from the proposed project sites. For example, the area of influence may include the watershed within which the project is located; any affected estuary and coastal zone; off-site areas required for resettlement or compensatory tracts; the airshed (e.g., where airborne pollution such as smoke or dust may enter or leave the area); migratory routes of humans, wildlife, or fish, particularly where they relate to public health, economic activities, or environmental conservation; and areas used for livelihood activities (e.g., hunting, fishing, grazing, gathering, and agriculture) or religious or ceremonial purposes of a customary nature.
