Trophy hunting can play an essential role in the conservation of African wildlife, according to a growing number of biologists.
Now some experts are calling for a program to regulate Africa's sport-hunting industry to ensure its conservation benefits.
According to a recent study, in the 23 African countries that allow sport hunting, 18,500 tourists pay over $200 million (U.S.) a year to hunt lions, leopards, elephants, warthogs, water buffalo, impala, and rhinos.
Private hunting operations in these countries control more than 540,000 square miles (1.4 million square kilometers) of land, the study also found. That's 22 percent more land than is protected by national parks.
As demand for land increases with swelling human populations, some conservationists are arguing that they can garner more effective results by working with hunters and taking a hand in regulating the industry.
Sport hunting can be sustainable if carefully managed, said Peter Lindsey, a conservation biologist with the University of Zimbabwe in Harare, who led the recent study.
"Trophy hunting is of key importance to conservation in Africa by creating [financial] incentives to promote and retain wildlife as a land use over vast areas," he said.
In an upcoming edition of the journal Conservation Biology Lindsey and an international team of colleagues call for a plan to increase the conservation benefits of sport hunting, including a certification program to more tightly regulate the industry.
"To justify the continued existence of [protected] areas in the context of increasing demand for land, wildlife has to pay for itself and contribute to the economy, and hunting provides an important means of achieving this," Lindsey said
