Borders and other debates (Paperback)

What happens on Brazil's borders? How does the city of Foz do Iguaçu, in Paraná, articulate with Ciudad del Este, in Paraguay? How did the poor population of Ciudad del Este unite to combat food shortages during the pandemic caused by the Covid-19 virus? How the introduction of the QR Code could become a trap for technology users? How did South American geopolitics play out between Brazil and Argentina during the border conflicts in 1952? These topics are addressed in this book, which may enrich the reader's knowledge and reflections.
