I think the management of quadriped animals on a population per continent versus a population per country/area is unrealistic. You may be able to partially manage fish and migratory birds on a continent wide basis,if you could get all parties to the table. With as many countries as Africa has, you would have as much chance of getting a consensus of opnion as Hillary does of getting the NRA endorsement for POTUS in 2008. Snowball fights in Cairo are a more likely scenario.
Whether it's elephants in souther Africa or whitetails in the Cleveland, Ohio MetroParks, an overpopulated animal segment does not usuall disperse enough to balance it's population. Some of the animals will migrate to an area with a lower population density and more available food sources, while many will stay behind and starve, become sick, or start finding other food sources which then creates human conflict
Relocation by people of overpopulated animals isn't always successfull, either.
