Climate change has caused a rise in sea levels. This has increased the amount of salt in fresh water (use )on coastal farms. As a result, farmers are (gradual) unable to use fields close to the sea.
However, Mare Van Rijsselberghe, a farmer in the Netherlands is now using a (mix)of sea and fresh water (grow)healthy and tasty vegetables.
He teamed up with scientists from the Free University of Amsterdam and divided a farm eight irrigated areas. Separate pipes pumped fresh and sea water, and computer program created water with eight levels of salinity(含盐度).
The water levels and the levels of salinity were controlled by computerisedmeasuring devices called "sensors". Mr. Van Rijsselberghesaid he was able to harvest vegetables from most of the eight test areas. He said the vegetables were smaller than grown in fresh water. But he said they also had more sugar and salt, so they tasted much (good).
He found that potatoes grew better than the other vegetables in the combination of sea and fresh water. Mr. Van Rijsselberghesaid four kinds of these potatoes would be sent to Pakistan thousands of hectares of land (damage) by salinization(盐化作用)last year.
