This Tiny Country Feeds the World
In a potato field near the Netherlands’ border with Belgium, Dutch farmer Jacob van den Borne is seated in the cabin of an immense harvester before an instrument panel worthy of the starship Enterprise.
From his perch 10 feet above the ground, he’s monitoring two drones—a driverless tractor roaming the fields and a quadcopter in the air—that provide detailed readings on soil chemistry, water content, nutrients, and growth, measuring the progress of every plant down to the individual potato. Van den Borne’s production numbers testify to the power of this “precision farming,” as it’s known. The global average yield of potatoes per acre is about nine tons. Van den Borne’s fields reliably produce more than 20.
That copious output is made all the more remarkable by the other side of the balance sheet: inputs. Almost two decades ago, the Dutch made a national commitment to sustainable agriculture under the rallying cry “Twice as much food using half as many resources.” Since 2000, van den Borne and many of his fellow farmers have reduced dependence on water for key crops by as much as 90 percent. They’ve almost completely eliminated the use of chemical pesticides on plants in greenhouses, and since 2009 Dutch poultry and livestock producers have cut their use of antibiotics by as much as 60 percent.
One more reason to marvel: The Netherlands is a small, densely populated country, with more than 1,300 inhabitants per square mile. It’s bereft of almost every resource long thought to be necessary for large-scale agriculture. Yet it’s the globe’s number two exporter of food as measured by value, second only to the United States, which has 270 times its landmass. How on Earth have the Dutch done it?
