Border Security

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