Australia's fires | Okavango Delta at risk

Posted by: The Conversation Global

Editor's note

This has been a difficult week for Australia’s Prime Minister Scott Morrison and his government. The powerful coverage of devastating bushfires has intensified pressure on a government already on the back foot over its climate policy, Michelle Grattan writes, which has exposed it as poorly equipped to deal with complex policy problems.

The Okavango Delta in southern Africa is a mosaic of water paths, floodplains and arid islands, created by various natural processes in a delicate balance. Its unique ecosystem, and the huge array of wildlife it attracts, have earned it World Heritage status. Michael Murray-Hudson and Olivier Dauteuil explain how some imminent changes, like higher global temperatures and the diversion of water for irrigation in upstream countries, could disrupt the balance.
