Environment, security, and terrorism in the trinational frontier of the Southern Cone

This article analyzes the transformations of notions of governmentality, security, and sovereignty behind recent processes of securitization in the trinational frontier of the Southern Cone, which encompasses the cities of Puerto Iguazú (Argentina), Ciudad del Este (Paraguay), and Foz do Iguaçú (Brazil). It examines how early concerns with security that were primarily focused on the territorial integrity of nation-states have been replaced with security concerns of a more global nature, which call into question established mechanisms of control, particularly those related to the defense of national borders. It examines how environmental concerns are increasingly becoming conflated with other current forms of securitization such as terrorism, popular unrest, and narcotraffic and it analyzes devastating effects of these processes on peoples of the South, particularly the poor.
