Botswana's Okavango Delta is one of Africa's most scenic and unspoiled wilderness areas, however, it is losing its wildlife at an alarming rate.

According to research, the species decline is the result of human encroachment, game fences and poaching. The most potent factor, however, is seen to be drought.
