Potato growing even in sea water may be a revolutionary step to save the food crisis

ByTommy Hemmert Olesen

One of the causes of the food crisis in the world,Salt wateringIt is said that there is a shortage of fresh water necessary for cultivation. In the past countermeasures were adopted a method of removing salt from sea water and the like to produce fresh water suitable for agriculture but potato growing even in seawater developed in the Netherlands revolutionized the production of future crops You may wake it up.

Potatoes are cultivated experimentally in the northern part of the NetherlandsTetheleAn area called Texel. Although it is an area that is influenced by salt all the way to be surrounded by the sea on all sides, potatoes are grown in an environment where crops do not grow if it is common by the development which has been advanced mainly by Mr. Marc van Raesselberge of 59 years old It is.

Mr. Van Raesselberger said about the current situation of fresh water shortage: "89% of the world's water is salt water, 50% of the farmland is in danger of salt watering, and hundreds of thousands of people I live in areas that have suffered salt damage.With these considerations, it is obvious that we have problems. " To this problem, Mr. Juan Reyselberge said, "People have focused on converting salt water to fresh water, but we decided to turn to the ones that nature already has." I talked about the efforts made with a new viewpoint.

Mr. Fan Reiserberger will establish a company "Saltfarm Texel" to develop technology,Free University of AmsterdamWe collaborated with research team of Tag to develop. Dr. Arjene de Vos at the same university tells the significance that "With this technology, salting water, which was conventionally regarded as a" problem ", will change to" opportunity ".

The mainstream current countermeasures against saltwatering are to treat salt-containing seawater to fresh water, and in the UK and London suffering from water shortagesSeawater desalination plant openedIn Saudi Arabia, 70% of the drinking water is covered with desalinated seawater. However, removing sea water components dissolved in water is costly and consumes a lot of energy at the same time. Therefore, it is true that many of the developing countries do not have enough physical strength to introduce facilities.

Pakistan is one of the areas suffering from salt damage, but in order to change such situation, test cultivation of potato developed by Mr. Van Rajselberger will be started. If we know that this experiment is successful and adaptable to the climate of Asia, there is a strong possibility that it will change the lives of people in the world who suffer from salt damage, as well as the food situation in Pakistan.


Mr. Van Rajselberger explained that he tried and tried to repeat his own efforts. "We are never a group of scholars, but a group of weird people who believe they can make a change, I hope to be partners with ordinary farmers."

"In the Netherlands, one-third of the country faces a crisis of salt damage, I made an embankment and made irrigation (irrigation) to make farmland, the other side of the levees belongs to fishermen , I thought that this side belonged to a farmer, but from now on, both sides need to work together to think about the way of new food production, "he says he needs to change the approach of food policy I will.


According to Mr. Fan Rajselberger, the salt that is sucked up from the roots passes through the interior of the potato and accumulates in the leaves. Therefore, even if you eat a lot of potatoes it is considered that it is almost impossible to fall into excessive salt.
