ABSTRACT
The peri-urban interface (PUI) is one zone of cities that has commanded a mounting volume of attention among geographers during recent times (Allen, 2003). The designation PUI suggests that it refers to where urban areas interface around their periphery with non-urban areas, usually assumed to be rural. It thus suggests three categories of land: urban, rural and peri-urban (the latter presumably could equally be accurately called peri-rural interface).
