Lessons from past droughts could shape future of Namibia
Some of the driest, hottest and dustiest parts of the world are set to experience even tougher conditions in the decades ahead, according to the latest forecasts of climate change.
One of the countries thought to be most vulnerable is Namibia which is in the grip of a severe drought. More than half a million people are receiving food aid, and so much dust is being blown into the atmosphere that it could affect the climate.
But there are hopes that lessons learnt from past droughts could help the country to move forward.
The BBC's science editor David Shukman reports.
