Food Production. An idea worth its salt

You turn the kitchen tap and there’s a brief splutter of brown gunk. Then nothing.


So you walk into the dustbowl you once called your garden and watch what’s happening in the street. People are queuing for water already — and you know you need to get in line soon to take your place with the rest of your neighbours, who’re already snaking along the pavements of your suburban block. The water bowser will be there at noon, delivered by the army, trying to make sure that everyone gets his or her 20l of life.


It’s the stuff of dystopian nightmares and Mad Max films. But given that the worlds of reality and dark futuristic dreams seem to be converging on the Mother City, it is perhaps not an unrealistic vision for summer at the end of 2018 there. The Western Cape’s dams teeter on the verge of being empty and its people may be finding it hard to imagine a time when baths and car washing were daily indulgences; and yet the province is a part of SA that is flanked with almost endless water — the ocean.


Desalinisation can make some of this usable, but the sea, salty as it is, might just offer another glimmer of hope to the parched province — by irrigating vegetables. Sound outrageous? How could harsh, brackish sea water be used to grow anything?...
