A study done by UCLA geographer have stated that they believe Osama Bin Laden to be hiding in a certain building in Parichinar, Pakistan. They came to this conclusion using spatial theory called distance-decay therory. The New York Times states:
Distance-decay theory states that as one goes further away from a precise location, there is an exponential decline in the turnover of species and a lower probability of finding the same composition of species. The theory of island biogeography states that large and close islands will have higher immigration rates and support more species with lower extinction rates than small isolated islands.
These theories can be applied over varying spatial scales to posit bin Laden’s current location based on his last reputed geographic location. Distance-decay theory would predict that he is closest to the point where he was last reported and, by extension, within a region that has a similar physical environment and cultural composition (that is, similar religious and political beliefs).
I new geographers would be the ones to find him!
