![]() The site is an outstanding example of the interplay between climatic, geomorphological, hydrological, and biological processes that drive and shape the system and of the manner in which the Okavango Delta’s plants and animals have adapted their lifecycles to the annual cycle of rains and flooding. The Delta’s dynamic geomorphological history has a major effect on the hydrology, determining water flow direction, inundation and dehydration of large areas within the Delta system. The Okavango River, at 1,500kms, is the third largest in southern Africa. The geology of the area, a part of the African Rift Valley System, has resulted in the ‘capture’ of the Okavango River that has formed the Delta and its extensive waterways, swamps, flooded grasslands and floodplains. The biota has uniquely adapted their growth and reproductive behaviour, particularly the flooded grassland biota, to be timed with the arrival of floodwater in the dry, winter season of Botswana. Furthermore it is in a near pristine state being a largely untransformed wetland system. It is Africa’s third largest alluvial fan and the continent’s largest endorheic delta. The Okavango Delta is one of a very few large inland delta systems without an outlet to the sea, known as an endorheic delta, its waters drain instead into the desert sands of the Kalahari Basin. ![]() The inscribed World Heritage property encompasses an area of 2,023,590 ha with a buffer zone of 2,286,630 ha. ![]() The area includes permanent swamps which cover approximately 600,000 ha along with up to 1.2m ha of seasonally flooded grassland. The Okavango Delta is a large low gradient alluvial fan or ‘Inland Delta’ located in north-western Botswana. ![]()

![]() ![]() ![]() The event’s schedule resembled any corporate conference, with some fairly noticeable twists. Previous conferences have taken place in Raleigh and Denver – while Brazil, Britain and Italy have also held flat-Earth conventions in recent years. Organizers told CNN that about 600 others went too. This week, the businessman attended the third annual Flat Earth International Conference, held at an Embassy Suites hotel in suburban Dallas, Texas. Weiss’ preferred community is those who share his life-altering belief. “It’s just not something I resonate with.” “I have no problem with anybody that wants to believe we live on a ball. Now, Weiss finds it tedious to associate with the majority of people – though he “unfortunately” still has some friends who believe in a round Earth. “It literally whips the rug out from underneath you.” “I absolutely freaked out,” Weiss tells CNN in a phone interview. Ever since he tried and failed to find proof of the Earth’s curve four years ago, he’s believed with an evident passion that our planet is both flat and stationary – and it’s turned his world upside down. “Would you wake up in the morning and want everyone to think you’re an idiot?”īut Weiss is a flat Earther. “I don’t want to be a flat Earther,” David Weiss says, his voice weary as he reflects on his personal awakening. ![]() |
