Located in the northeast of Africa’s Kalahari Desert and southeast of the Okavango Delta, the Makgadikgadi Salt Pans are the largest in Africa and among the largest in the world. These expansive salt flats cover approximately 30,000 square kilometres (10,000 square miles) within the borders of Botswana’s Makgadikgadi National Park and Nxai Pan National Park, second only to Bolivia’s Salar de Uyuni in scale.
The salt pans are the remnants of an ancient inland sea, once one of the largest on Earth. Scientists believe this massive lake, known as Lake Makgadikgadi, once spanned between 80,000 and 275,000 square kilometres. Over time, tectonic activity and climate changes redirected the Okavango, Zambezi, and Cuando rivers, leading to the lake’s eventual desiccation.
For most of the year, the Makgadikgadi Salt Pans are an arid, shimmering white landscape, inhospitable to most life forms except for algae. However, the rainy season, from approximately November to March, transforms this stark environment into a vital wetland. Water flows in from the Boteti and Nata rivers, filling ephemeral ponds, watering holes, and shallow lakes, thereby creating lush, temporary grasslands.
This seasonal transformation attracts a diverse array of wildlife, including migrating wildebeest and zebras, along with their predators. The newly formed waters also become a haven for a variety of bird species such as ducks, geese, pelicans, and flamingos. Notably, the Makgadikgadi Salt Pans are one of only two breeding sites for flamingos in southern Africa.
The unique ecological dynamics of the Makgadikgadi Salt Pans make them a fascinating destination for those interested in both the natural history and the seasonal wildlife phenomena of Botswana.
