For centuries, present-day Arizona’s desert borderlands have been corridors connecting northern and southern peoples. These passages themselves have undergone transformations – cycles that included times of lesser and greater violence. In this presentation, Dr. John F. Chamblee, a long-time Humane Borders volunteer and head of their mapping project, will discuss a most recent borderlands transformation by providing a historical view of the migrant death mapping project’s data. By looking at changes in death rates and locations, he will explore connections between globalization, border policy, drug trafficking and increasing mortality rates over the last decade within Arizona’s undocumented migrant travel corridors.
