Before Ghost Cartels, it was a free city run by cartels and pretending to be Colombia; until 2073, when Aztlan started seeding toxic SURGEd trees because they could. Amazonia, known for loving trees and hating people, discovered it's love for people and hatred for trees that eat them and launched an attack on an Aztlan hospital because a snickering snitch told them they totally do experiments with gentech there (actually they were patching up little children). Apparently they let Sirrug do the planning, because they don't seem to have gathered any intel or anything.
Aztlan cries foul bloody murder and goes to war in 2074, flattening half the city because they could and a good deal of the surrounding jungle with masses of heavy vehicles. Amazonia fought back, using the
surrounding jungle to their full advantage. This developed into a stalemate, a situation War elaborates on. Also, keep in mind Bogotá has immediate access to the sea for shallow waters DIY cartel submarines and is a major seaport.

Judging from the outtakes from Stormfron, Aztlan will win the war and Bogotá by 2075.
Bottom line: Do yourself a favor and and read
the wikipedia entry on Bogotá to get a better picture of the city than War offers. You can still use the info in it, I guess, but the wiki article and maybe an online travel guide will massively help you with things like maps and getting a feel for the location.
