Top 100 spectacular natural landmarks of the world (P.98) Okavango: The vast verdant oasis in the middle of the arid continent


( The delta is one of the Seven Natural Wonders of Africa.

The Okavango Delta in Botswana is a swampy inland delta formed where the Okavango River reaches a tectonic trough at an altitude of 930–1,000 m in the central part of the endorheic basin of the Kalahari.


The Okavango Delta is as complex as it is beautiful. Surrounded by desert, it’s completely sustained by seasonal rains that nourish a staggering range of plant and animal life. Seasonal flooding swells and replenishes this verdant oasis, attracting huge numbers of iconic wildlife that move between fertile plains, marshlands, and huddles of shaded islands. When the floodwater recedes, the Delta shrinks, concentrating animal numbers and making for some of the very best game viewing in the world.


The delta is very flat, with less than a 2 m variation in height across its 15,000 km2, while the water drops about 60 m from Mohembo to Maun. Thus, Okavango offers an extremely large and majestic view for anyone who visits. This is even more exact at dusk and dawn.


The Okavango Delta is renowned as an extraordinary ecosystem of high biodiversity, listed as both a Ramsar and World Heritage Site, with part protected in the Moremi Game Reserve. This extensive floodplain ecosystem has 444 recorded bird species, with just under a quarter of these waterbirds, including at least 16 breeding and 4 threatened (1 endangered, 3 vulnerable) species. Despite the global importance of this ecosystem and its transboundary nature, there are surprisingly few long-term assessments of the status of the ecosystem or waterbird communities, a key indicator of ecosystem health, with threats such as upstream water extraction, and climate change threatening its outstanding biodiversity.


The delta was named one of the Seven Natural Wonders of Africa, which was officially declared on 11 February 2013 in Arusha, Tanzania. On 22 June 2014, the Okavango Delta became the 1000th site to be officially inscribed on the UNESCO World Heritage List.
