Botswana is a landlocked nation that houses the Okavango Delta, the world’s largest inland delta system. Instead of flowing into an ocean, the Okavango River empties directly into the sands of the Kalahari Desert, creating a 15,000-square-kilometre seasonal oasis in an otherwise hyper-arid basin. To protect this fragile ecosystem, Botswana enforces a strict low-volume, high-yield tourism model, purposely limiting lodge capacities to maintain one of the lowest environmental footprints and highest concentrations of free-roaming elephants on Earth.
