Paragliding is an unforgiving sport: you're gliding, hoping to find updrafts to give you some more altitude so you can reach high enough to cross to another spot that hopefully also has an updraft, etc.

At a guess, this guy was hoping that he'd find a last-resort updraft in this area. OP, do you live maybe in a small-ish built area surrounded by fields or forest? Those tend to get hotter than their surroundings and are great for updrafts. But generally you don't want to land in residential areas, there full of obstacles which make for unpleasant landing conditions.
