A combination of ancient tectonic movements and contrary hydrology have given rise to rivers that never reach the sea, but rather flow inland to create a stunning mosaic of ecosystems.
The annual flooding of the Okavango Delta is driven not by local rainfall, but by the rains that fall in the far-off highlands of Angola. These floodwaters meander more than 1000 kilometres to Botswana, flooding the Delta before soaking into the sands of the Kalahari. Along the way they create a unique habitat for a myriad aquatic species, supporting an abundant ecosystem.
