Tracy McVeigh on a Dutch experiment to develop food crops that can be irrigated with salt water:
Here, on one of the Netherlands’ northernmost islands, windswept Texel (pronounced Tessel) surrounded by encroaching ocean and salt marshes that seep sea water under its dykes and into ditches and canals, an enterprising farmer has taken the radical step of embracing salt water instead of fighting to keep it out. And now he thinks he might just help feed the world.
Inspired by sea cabbage, 59-year-old Marc van Rijsselberghe set up Salt Farm Texel and teamed up with the Free University in Amsterdam, which sent him [researcher Dr Arjen] de Vos to look at the possibility of growing food using non-fresh water. Their non-GM, non-laboratory-based experiments had help from an elderly Dutch farmer who has a geekish knowledge of thousands of different potato varieties.
“The world’s water is 89% salinated, 50% of agricultural land is threatened by salt water, and there are millions of people living in salt-contaminated areas. So it’s not hard to see we have a slight problem,” said van Rijsselberghe. “Up until now everyone has been concentrating on how to turn the salt water into fresh water; we are looking at what nature has already provided us with.”
