Source of water in the Okavango Delta identified

The long-standing mystery of where the Okavango Delta’s water comes from has been solved. An international team of scientists and researchers identified what keeps the delta alive in the middle of the Kalahari Desert, one of Africa’s driest regions. The study found that a huge underground water tower has been operating quietly for thousands of years. This hidden system supplies water to millions of living things and helps protect the ecosystem in southern Africa from drought and water shortages.
