Borders and Walls: Do Barriers Deter Unauthorized Migration?
In 2015, borders and walls seemed to burst onto the global agenda in the context of migration and halting spontaneous movement. Countries as diverse as Austria, Bulgaria, Estonia, Hungary, Kenya, Saudi Arabia, and Tunisia announced or began work on new border barriers. This trend has continued apace in 2016, with Bulgaria, Hungary, and Austria expanding their fences, Norway building a fence on its Russian border, the United Kingdom funding a wall in Calais, France, and Pakistan building a fence on its border with Afghanistan.
