Border Security

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.

Over the past several decades, in response to the uptick in spontaneous migration flows, there has been a surge in construction of border walls and fences. This trend begs several questions: Why now? Did border walls work in the past? Do they work today? This article examines the history of border barriers and assesses how effective they are at deterring unauthorized migration.

Two years on, the Australia-Cambodia refugee relocation agreement—the first of its kind involving a traditional resettlement country relocating refugees to a country with no resettlement track record—has proven to be underwhelming in its outcomes. Only five refugees have been voluntarily relocated under the deal, of whom just one remains in Cambodia. This article explores where the deal went wrong and what lies ahead for Australia’s detained asylum seekers.

The stark contrast between the Republican and Democratic parties on immigration was codified in their 2016 party platforms, and showcased in the rosters of convention speakers—featuring victims of unauthorized immigrant crimes on the one hand, and unauthorized immigrants living in fear on the other. This article explores the evidence, even compared to earlier platforms, of two divergent universes regarding immigration.

News of the Zika virus outbreak in Latin America has raised alarm bells, resulting in scattered calls for tighter restrictions on international entries to the United States. Evidence shows, however, that closing borders and restrictions on international travel tend to have little impact on the spread of infectious diseases. This feature article explores the linkages between public health and migration in the Americas.

Movements of migrants and asylum seekers in the Mediterranean have shown to be highly fluid, adapting quickly to changing conditions at origin, transit, and destination. This article examines the shifts in flows across the three major Mediterranean routes since 2008 and the complex web of often interconnected factors underpinning these movements.
