1
The Netherlands is the second largest exporter of agricultural products in the world, despite being only a little bigger than the state of Maryland.
2
How does a country this size even come close to the U .S., the world's top exporter?
3
By devoting more than half of its land to farming, and focusing on high -value goods like eggs,
4
meat, cheese, tomatoes, and peppers.
5
We are sweet and tiny.
6
It's in our genes, you know, it's our DNA.
7
In 2024 alone, the Dutch farmed goods worth over $140 billion.
8
The country pioneered greenhouse growing and now uses robots and algorithms that predict yield, optimize water use, and can even tell when a tomato is ripe.
9
But its position at the top is being threatened.
10
Soaring energy prices, labor shortages, and new rules limiting pollution or squeezing the industry.
11
So how did the Dutch become a global agricultural powerhouse?
12
And more importantly, what can its model teach the rest of the world about how to grow more with less?
13
In the 13th century, nearly a fifth of what is now the Netherlands was underwater.
14
So the Dutch built dikes to hold back the sea and pioneered the use of windmills to pump out the leftover water.
15
Over centuries, a complex system of pumps kept low -lying land dry.
16
And from this reclaimed land, small family farms fed the country.
17
But that all changed during
18
World War II, when Nazi Germany took over.
19
In 1944, Dutch rail workers went on strike, protesting the occupation.
20
In response, the Nazis cut off food supplies.
21
Over five months, 20 ,000 people died from starvation.
22
It became known as the winter of hunger.
23
After the war, food security became a national priority.
24
Under the new agricultural minister, Siko Mansholt, the government industrialized farming.
25
He subsidized important agricultural products and merged farms into bigger, more efficient ones.
26
Public investment in research and education transformed Wageningen University into the country's secret weapon.
27
Its research has been used in over 150 countries.
28
Over the years, it has spun off dozens of startups.
29
This one gathers electricity from living plants, and this one builds robotic harvesters.
30
You can find
31
Dutch -inspired greenhouses covering thousands of acres in Spain, Canada, and China.
32
It all started in Westland, an area just outside of Rotterdam, with one of the world's largest concentrations of greenhouses.
33
After dark, they light up the horizon in orange, purple, and green hues from the powerful lamps used to speed up plant growth.
34
Some people say it will never be really dark in Westland.
35
Here, Marguerite Looye runs a third -generation tomato farm called Looye Kukers.
36
How did your grandfather grow vegetables?
37
I'm guessing it didn't look like this.
38
No, no, not at all.
39
It was completely different than in these days.
40
In these greenhouses, plants can grow a foot a week.
41
Marguerite's team prunes, wraps, and lowers each one by hand.
42
If you didn't control the vines...
43
Oh, yeah, then you will get the jungle.
44
The Netherlands exports more than 900 ,000 tons of tomatoes a year,
45
despite having a climate that's naturally too cold and rainy for these warm weather fruits.
46
While high -tech solutions help them grow faster and year -round, they still need bees to pollinate every plant.
47
You cannot do it without them.
48
So they are probably one of the most important tools that we have in our glass house.
49
When they're not pollinating, they live in these bee hotels.
50
In each box are around 800 bumblebees.
51
You can hear them making more noise.
52
Now they are still cool.
53
Overhead, LED lights mimic the sun and create optimal summer conditions year -round.
54
Developed by scientists at Wacheningen, these lights run more efficiently than older sodium bulbs.
55
With the same electricity, you can get almost double light.
56
Watering these plants has also become more efficient.
57
Over the last two decades, greenhouses have reduced their water usage by as much as 90%.
58
The water will fall here and it will go back at the end of the row
59
and then it will go into a drain, silo.
60
We will clean this water and we will reuse it.
61
That means it takes just four liters of water to grow a kilo of Dutch tomatoes, compared to the global average of more than 200 liters.
62
While tech has optimized much of the growing process, humans still pick tomatoes better than robots, which struggle to see the fruit through these dense vines.
63
It's ready to be harvested when the last tomato, this one, is completely red.
64
For example, these two are just perfect.
65
These are ready to be harvested because that's the moment when they have the best taste.
66
Workers follow this chart to harvest tomatoes at peak flavor.
67
This is green, so it's color number three, so not ready.
68
This, oh, then this is quite red, but it's still not red enough.
69
It's color number eight, so this one will be harvested with the second round this week.
70
Because Loya only picks ripe fruit, it has a small window to get it into cold storage before it spoils.
71
Today the tomatoes came, we packed them in the night shift and tomorrow morning everything goes away with the trucks.
72
So to help speed up production, this tomato camera.
73
He's looking for damage, split.
74
The machine takes two pictures, one from the top and one from the bottom.
75
This one we see there he had found one split. Must be somewhere.
76
Workers still check the bigger tomatoes by hand.
77
We are checking for the size.
78
It must be between 47 and 62 millimeters.
79
If you see like this, here you missed one tomato.
80
It's not so nice.
81
And when you look like this, and then we say this is nice but this too are too small.
82
Robots do a lot around here.
83
This machine on the main factory floor helps sort out tomatoes that are too small or too yellow for the premium brand.
84
The green one we throw away because it costs too much time and it's older tomatoes, the taste is not so well.
85
Machines also sort the reddest and sweetest tomatoes one last time.
86
Then workers package them by hand at these stations so they're ready to ship out.
87
But tomato greenhouses aren't the only ones relying on lots of tech.
88
Just a few miles away,
89
Arnaud de Van Dijk runs one of the largest pepper operations in the country. to keep them healthy.
90
So it asks every day a lot of attention to the nature.
91
Nature is a very complex thing.
92
Every year, Wiedi Holland grows 85 million peppers.
93
Like tomatoes, these peppers are grown hydroponically, meaning not in the ground.
94
And here too, computers monitor and adjust everything from temperature and watering schedules to lighting.
95
These yellow cards track pests, like white flies or thrips.
96
The insects are tracking to the color of the green.
97
They are being taken by the color of the green.
98
And soon cameras will be able to read the sticky cards themselves.
99
We are going to a situation where we can monitor which insects are in the store.
100
And the sooner we detect a plague, the better and easier we can keep these biologists under control.
101
Together these innovations have allowed
102
Dutch growers to achieve yields 12 times higher than the average pepper farm globally. Since 2007,
103
the company has also used automated carts guided by wires in
104
the floor to move harvested peppers from the greenhouse to the processing hall.
105
On the packaging floor, AI -powered cameras take pictures of each pepper, comparing the images to a database of ideal fruit.
106
That information is used to sort the peppers by size, weight, shape, and color.
107
Ones with small imperfections don't go to waste.
108
The company sells them to salad producers and other food processors.
109
The ones that do pass the camera stage go on to packaging.
110
This machine drops nearly 400 pounds of perfect peppers into each crate.
111
More and more automatic palletizing and self -driving forklifts are replacing humans in this factory.
112
The Netherlands is facing a growing labor crisis, with two -thirds of businesses struggling to find workers.
113
VD Hollen introduced all this new technology to automate as much of the packaging process as possible.
114
As much as 95 % of Wiede Holland's bell peppers are exported, and about 60 % of all crops produced in the Netherlands leave the country.
115
Its position on the North Sea makes it easy to ship from giant ports in Rotterdam and Amsterdam.
116
Germany is the top buyer, but Dutch produce also reaches the UK, China, and the US.
117
Producing and packing all of this food requires a lot of energy.
118
Greenhouses across the Netherlands use nearly 107 petajoules, enough to power more than 2 million homes a year.
119
And not everyone's happy about this.
120
Some studies estimate that a greenhouse -grown tomato could have six times the carbon footprint of a field -grown one.
121
But that largely depends on the energy source used to grow them.
122
That's why Dutch growers are trying to change how their farms are powered.
123
Until recently, much of their energy came from Russian gas.
124
But the war in Ukraine forced the Netherlands to cut off imports.
125
Energy prices soared as a result, forcing many greenhouses to look for alternatives.
126
Loja already had its own power plant on site.
127
Heat from the energy producing process actually warms the greenhouse, and any extra energy is sold back to the power grid.
128
Vidi Hollen, meanwhile, turned to a different source.
129
50 % of the warmte -behoefte is not made as a earth -warmte.
130
The company invested $46 million, along with a few other growers, to drill for the renewable energy source.
131
We have our gas -use use, and we have been in the warmte.
132
I'm proud of that.
133
Wageningen University is working with growers to reduce their energy consumption.
134
Leo Marcellus is largely credited for the widespread use of LED lights in Dutch greenhouses.
135
Without light, there is no plant growth.
136
Custom LED light recipes have helped farmers grow strawberries, cucumber and asparagus faster.
137
His research on these lights got glasshouses in the country to cut their power usage by nearly half.
138
And now Leo and his team are seeing if they can take it further.
139
The question is, can we make as efficient use of the LED lighting as possible?
140
Now he's studying how LED light color, intensity and timing can influence growth and lower energy bills.
141
And here we are doing an experimental setup where we are growing lettuce with different light.
142
In this lettuce trial, his team figured out that by increasing the light intensity in the final week before harvest,
143
they can raise vitamin C and sugar content and extend shelf life.
144
What gives a good growth?
145
What gives a good taste?
146
What gives a good nutritional value?
147
But also, what is most sustainable in terms of less use of energy?
148
And usually that can be a balancing act.
149
In another room, his team is working with the Singapore Food Agency on bok choy.
150
Here I can choose any condition.
151
If I give them low light and a low temperature, they will grow slowly.
152
By adjusting temperature, CO2 and light, they can speed up plant growth.
153
Many of these testing rooms are pink because red LED lights are better for growing plants.
154
Red LEDs are the most efficient in converting electricity into light.
155
So a high fraction of red is normally, I would say, advisable.
156
But it has to be the perfect balance of red, blue and white light.
157
For example, this bok choy likes a little more white light.
158
If it is only red, most plants don't like that.
159
Leo's colleague Elena Vincenzi is studying how barely visible red light affects a tomato's plant's ability to convert light into energy.
160
Here you can see that there is a chamber
161
that can be clipped on a leaf and then because the chamber is transparent,
162
the leaf can still receive the light that we give to our normal treatments
163
and we are able through the machine to actually see what is the rate of photosynthesis.
164
If the photosynthesis rate is higher, then perhaps the plant with the same amount of light can grow more and faster.
165
She's also trying to reduce water use.
166
Swapping in different kinds of growing bases for tomatoes can help with that.
167
They're also studying how more robots can help reduce labor costs.
168
Several things are studied.
169
One of them is about robotic harvesting of the plants.
170
There's a lot of interest, of course, in replacing the manual labor by robots.
171
Much of what's discovered at Wagening ends up back on farms like Loja and Wiede -Holland.
172
Growers often also partly fund the research that we're doing here.
173
This tight feedback loop between scientists and farmers may be the secret to what makes
174
Dutch agriculture so efficient.
175
It dates back to the post -war era, when the Dutch government encouraged researchers and farmers to work together.
176
When I was a kid, my father, every Monday or Tuesday evening, I think, he had a study club.
177
And then they were with a few growers and they visited their greenhouses.
178
I think things like that were very, very positive for the development of our industry.
179
Now Wageningen's research is pushing innovation beyond growing plants.
180
The Netherlands is Europe's top exporter of meat, raising 4 million cows, 13 million pigs and 104 million chickens every year.
181
All that livestock, especially cows for beef and dairy, comes with a high environmental cost.
182
And it's not just carbon emissions.
183
The bigger issue here is ammonia, a nitrogen -rich gas released from fertilizers, manure and urine.
184
In 2017, the Netherlands emitted more ammonia per hectare than any other European country.
185
Why?
186
Because it has the highest livestock density on the continent.
187
Environmentalists say this type of pollution is stressing the native ecosystem.
188
Excess nitrogen means tall, fast -growing grasses overtake more delicate native species.
189
And it causes algae blooms in waterways.
190
To cut emissions, the Dutch government started buying out high -emitting farms
191
but calls to limit these emissions have triggered mass protests across the country.
192
One place trying to find a solution is Wageningen's dairy campus.
193
This is not a commercial dairy farm.
194
It's a research center.
195
Campus manager Kies de Koning and his team are focused on reducing nitrogen emissions from cows, starting from the ground up.
196
They're testing floors that separate pee from poop, since mixing these two releases more ammonia.
197
We can run trials where we separate the urine and the solids.
198
The separated waste is stored in tanks under the barn to prevent emissions from escaping.
199
They've also experimented with robot cleaners, but each one costs nearly $30 ,000.
200
A steep price for most farms, which would need at least two.
201
The more accessible solution?
202
Changing the cows' diets.
203
So, can we feed cows in such a way that we have less ammonia emission or less nitrogen losses?
204
They're testing different feed combinations with the help of AI -powered troughs,
205
which track how much each cow eats and how much methane and ammonia it produces.
206
They've already found that replacing fermented grass with maize or fresh grass helps cut methane emissions.
207
And when they lower protein and nitrogen levels in the feed itself, the cows will release less ammonia.
208
Researchers are also using AI to track cows' health.
209
The technology can spot issues like foot rot and identify low emission cows for breeding.
210
The Netherlands turned its flood -prone country into an agricultural powerhouse and exported that knowledge around the world.
211
But does Dutch innovation hold the secret to feeding the globe?
212
The fact is that there is almost a billion people on the planet that go hungry every day.
213
Jonas Jägermeier is a climate scientist and crop modeler at Columbia University.
214
He points out that half of the calories humans eat come from crops that are grown outdoors.
215
Grains like wheat, rice and corn.
216
But we're not going to grow staple crops or calorie providing grain crops in a greenhouse environment anytime soon.
217
Simply because of financial requirements.
218
To reproduce an equal number in harvest, in caloric production, say in a desert environment,
219
coupled with a desalination plant that is using renewable energy, that is a sci -fi scenario that is promising,
220
but we're not quite there yet.
221
So to replicate those millions and millions of hectares of cornfields somewhere indoor is simply not feasible.
222
The farms of the future will have to rely on more than just tech.
223
They'll need water, seeds, energy, local knowledge, and adaptable systems.
224
There is no silver bullet.
225
Any implementation strategy that would help change how farmers do practice, how food is processed and transported,
226
and how food is then brought to the consumer needs to be in a locally tailored strategy.
227
Jonas is now building AI tools that can give farmers early warnings of seasonal forecasts, fine -tune water use, and more importantly,
228
connect growers across continents, allowing them to share insights in real time.
229
Maybe the real
230
Dutch export isn't tomatoes, beef, or robot harvesters.
231
It's a mindset, one that values collaboration over competition and policies that drive efficiency.
232
The Dutch can't feed the world alone.
233
but they've forever changed the way it feeds itself.
