Under the blazing Colombian sun, Germán Balera pushes a small cart loaded with a few thermoses of coffee and packs of cigarettes across a derelict airport runway and into a labyrinth of ramshackle huts of corrugated zinc, plastic sheets and cardboard.
Balera is a resident of La Pista, Colombia’s largest informal settlement that is home to approximately 14,000 people on the outskirts of the city of Maicao in north-east Colombia. They are crammed into 12 makeshift blocks spread along the 1.2km runway of the dusty city’s abandoned airport, in the arid Colombian province of La Guajira.
