The Arid Zone is an interactive documentary that lets you visit the city of Mesa, Arizona, voted by MIT and UCLA universities as the most conservative big city in the United States. Using a questionnaire and an interactive map, the visitor can explore places in the city such as the Mexican border, Mormon churches, and a rodeo, as well as talk to residents about everyday life and current political issues. Filmmaker Fernanda Pessoa was an exchange student in Mesa in 2001, and returned to the city to make the project two months before Donald Trump was elected in 2016. Arid Zone is also a feature-length documentary. Shown in exhibition version in Mostra Labmis 2018 and exhibition In the present, life (is) political.
