The Okavango Delta, a Ramsar site and proposed World Heritage Site, is threatened by industry, farming, mining, tourism and not least the need for water and electricity in surrounding populations.
The Okavango Delta (or Okavango Swamp), in Botswana, is the world's largest inland delta. It is formed by rivers that rise in the Angolan highlands becoming the Okavango and Kwando Rivers. They create an unrivalled wetland as they disappear into the sands of the Kalahari Desert, where most of the water is lost to evaporation and transpiration instead of draining into the sea. Each year approximately 11 cubic kilometres of water irrigate the 15,000 km² area and some flood-waters drain into Lake Ngami. The Moremi Game Reserve, a National Park, spreads across the eastern side of the delta.
The area was once part of Lake Makgadikgadi, an ancient lake that mostly dried up by the early Holocene
A major part of the Delta has been designated as the Moremi Game Reserve. The Delta is a major centre of eco-tourism which is the second most important contribution to the economy of Botswana. A significant proportion of visitors are opinion formers in their own countries. However local guides have difficulties in identifying the plants and thus giving greater visitor appreciation of the ecology and conservation issues of the area.
The Delta’s flora is believed to contain at least 1350 species of plants and includes significant populations of endangered species.
