What will you do with the belt if you are dropped in a desert with only a belt on?
I'd probably die of dehydration while wondering what to do with the damned belt.
Maybe I could use it to make a perpendicular and cast a shadow, so I can determine a direction by the shadow and not walk circles...
Also use the buckle to reflect the sun and try and signal someone. Hopefully another naked person who happens to be a lady
Though I'm sure if your out there long enough it will stop looking like a belt and you could end up eating it lol
Tighten the belt around cactus and other plants to try and squeeze water out of them.
Honestly, I would simply try to find a road and during the day I would want shade.
Carry it with me and use it as a weapon if need be
probably hang myself with it
