How did the Netherlands, a country better known for its tulips, become a leading tomato producer and the top exporter of onions and potatoes? With more than half its land area used for agriculture, the nation is a pioneer in greenhouse horticulture. Dutch farmers are trailbrazing innovative methods that result in producing more food with fewer resources—methods that are increasingly relevant as climate change and more dramatic cycles of drought and flooding wreak havoc on traditional farming, coupled with a global population on target to reach 10 billion by 2050.
The Dutch landscape is home to swaths of greenhouses that minimize gas, electricity, and water usage along with greenhouse gas emissions while maximizing the use of sunlight and recycling nutrients. Further innovation comes in the form of the buildings themselves—construction materials, lighting, and heating and cooling systems.
But not every strategy is necessarily high-tech. Some tap the power of nature. To reduce the use of pesticides, many growers have turned to what’s known as “biocontrol” to protect their crops, using insects, mites, and microscopic worms to feed on damaging pests.
State-of-the-art technology also fuels the business of getting produce and flowers to market. Round-the-clock packaging plants and highly-automated cargo terminals at the port of Rotterdam help maintain the country’s rank as the number two global exporter of food products (by value) behind the United States.
Now the country has added knowledge and technology to its extensive list of exports. The government, universities, research institutes, and private growers and breeders are involved in food systems projects around the world. This export of knowledge also happens on Dutch soil—at university campuses where thousands of international students earn degrees to help address food security issues in their home countries.
