In super generalized terms, in 2030 of the six billion people on the earth, about two billion will live in informal settlements throughout the world. The most unwieldy and well-known places are connected to major cities such as Accra (Agbogbloshie), Mumbai (Dharavi), Cape Town (Joe Slovo) Barranquilla (Barlovento), Sao Paolo and Mexico City (The Favelas, un paraíso de las jaulas). Other settlements of the developed world are far more difficult to locate and define.
There are many settlements to name, but I came across a phrase from the poetry of Octavio Paz describing the sprawling urban landscape of Mexico City as “a paradise of cages” that struck me as perfectly non-judgmental.
