There have been several attempts at moving icebergs to end droughts.
In 2017, the UAE was experiencing severe water shortages and a project was set up to tow an iceberg to the region.
These plans involved harvesting icebergs from Heard Island, around 600 miles (1,000 kilometres) off the coast of mainland Antarctica.
The only details provided at the time, was that towing would be the most likely method.
South Africa in 2018 is experiencing its worst drought for a century.
A renowned marine salvage master from the country also believes towing an iceberg could be the answer.
Cape Town-based Nick Sloane, director of Resolve Marine, wants to tow a rogue iceberg 1,200 miles form the Antarctic ocean to Cape Town.
He intends to do this by using a material skirt, made of a specialist geotextile, which would fit around the underside of the huge chunk of ice.
In order for this to be successful, the iceberg must be of specific size and shape, with steep sides.
Huge tankers would guide and pull the iceberg through the water and the skirt would help reduce evaporation.
A milling machine would then then cut into the ice, producing a slurry and forming a saucer structure that will speed up the natural process, he said.
The removal of the salt from the water would require huge desalination plants, and a large injection of cash to build plants capable of processing several thousand tonnes.
