This Tiny Country Feeds the World

[Holland's indoor,] climate-controlled farms enable a country located a scant thousand miles from the Arctic Circle to be a global leader in exports of a fair-weather fruit: the tomato. The Dutch are also the world's top exporter of potatoes and onions and the second largest exporter of vegetables overall in terms of value. More than a third of all global trade in vegetable seeds originates in the Netherlands.

... by 2050, the Earth will be home to as many as 10 billion people, up from today's 7.5 billion. If massive increases in agricultural yield are not achieved, matched by massive decreases in the use of water and fossil fuels, a billion or more people may face starvation. Hunger could be the 21st century's most urgent problem, and the visionaries working in Food Valley believe they have found innovative solutions. The wherewithal to stave off catastrophic famine is within reach, van den Ende insists. His optimism rests on feedback from more than a thousand WUR projects in more than 140 countries and on its formal pacts with governments and universities on six continents to share advances and implement them.

A conversation with van den Ende is a white-knuckle ride on a torrent of brainstorms, statistics, and predictions. African drought? "Water isn't the fundamental problem. It's poor soil," he says. "The absence of nutrients can be offset by cultivating plants that act in symbiosis with certain bacteria to produce their own fertilizer." The soaring cost of grain to feed animals? "Feed them grasshoppers instead," he says. One hectare of land yields one metric ton of soy protein, a common livestock feed, a year. The same amount of land can produce 150 tons of insect protein.
