Border Security

In an era when countries are increasingly exposed to the opportunities and risks associated with the rising global movement of people, policymakers are rethinking approaches to border controls and border management. These policies and programs run the gamut—from facilitating legitimate mobility of people and trade to thwarting unauthorized movements, the latter a significant preoccupation in the post-9/11 era and as publics have become ever less accepting of unauthorized immigration. The research offered here examines the management of borders, enforcement policies and initiatives, and border security technologies.
