0:12 - 0:16MAKING THE FUTURE
-
0:16 - 0:20Indoor Farming
-
0:21 - 0:22Thank you very much.
-
0:22 - 0:26There are quite
some misconceptions about growing -
0:26 - 0:29and today I would like to help you to overcome
-
0:29 - 0:33at least seven of these misconceptions.
-
0:33 - 0:36So the first misconception is
that we can keep feeding -
0:36 - 0:38the world's expanding population
-
0:38 - 0:43with the existing agricultural technology.
-
0:43 - 0:46When we have a closer look at the world,
-
0:46 - 0:48we see that we are growing
-
0:48 - 0:52from 7 billion to 9 billion,
and that we are moving -
0:52 - 0:55to live more and more in cities.
-
0:55 - 0:59To produce enough food for all these people,
-
0:59 - 1:04water is the most important asset.
-
1:04 - 1:07In future, water will be more important
-
1:07 - 1:10than fossil fuel or energy is today.
-
1:10 - 1:12In order to produce enough food,
-
1:12 - 1:19we will create new land
for growing food in sub‑optimal conditions. -
1:19 - 1:24In those conditions, plants are not very happy,
and they will become ill. -
1:24 - 1:26They will get pests and diseases.
-
1:26 - 1:31We will take more and more pesticides,
chemicals, to treat them. -
1:31 - 1:36Another thing: even if our trucks
would run on water in future, -
1:36 - 1:4135 % of the trucks on the road are busy transporting
-
1:41 - 1:46food or food parts from A to B,
and probably, in the end, back to A. -
1:46 - 1:52So we have to change the way
that we feed the world today. -
1:52 - 1:57The second misconception:
we must make plants adapt to nature. -
1:57 - 2:04This is not true. In nature,
and even in the best Dutch greenhouses, -
2:04 - 2:08plants only use 9 % of their potentiality.
-
2:08 - 2:12In real nature, they maybe use 2 or 3 %.
-
2:12 - 2:17So plants are so very smart
that they are able to adapt any circumstances -
2:17 - 2:20in order to survive.
They can do that with very little -
2:20 - 2:26of their potentiality. But that opens
a lot of possibilities for us. -
2:26 - 2:31If we would know how to make plants
really happy, they are able to bring -
2:31 - 2:38much more to us. We started back in 1989,
23 years ago, studying plants -
2:38 - 2:44as they grow in the fields, in greenhouses.
We have worked for almost -
2:44 - 2:4710 years on producing mathematical models,
in order to understand them. -
2:47 - 2:51The more we understood about plants,
the more we started to see -
2:51 - 2:54that plants could do much better.
-
2:54 - 2:59The third misconception is,
this is paradise for plants. -
2:59 - 3:06It's not true ‑‑ this is paradise for us.
If plants were to choose, -
3:06 - 3:11they would say, "This is paradise."
Plants don't like sunlight. -
3:11 - 3:15They have used to live under the sunlight,
but the only light -
3:15 - 3:21that they take up from the sunlight is red and blue,
and a little far red. -
3:21 - 3:26So this is what plant paradise really looks like.
It's a merger of plant -
3:26 - 3:33physiological know‑how and high technology.
We give plants only red, -
3:33 - 3:39blue and far red LED light,
and we combine that with very sophisticated -
3:39 - 3:48climate control. By doing so,
we are able to grow crops in this kind of buildings. -
3:48 - 3:51We call this a plant production unit. It's a multi‑layer
-
3:51 - 3:54production unit and we can make it multi‑layer,
-
3:54 - 3:56because we don't want any sunlight.
-
3:56 - 4:02In the unit itself,
there is only this mixture of red and blue. -
4:02 - 4:04And in front of the unit where the people are working,
of course there is daylight, -
4:04 - 4:09or white light. Otherwise, you couldn't see
the real colors of the crops. -
4:10 - 4:15If we would have to produce
200 grams of fresh vegetables -
4:15 - 4:18and fruits for one person a day,
-
4:18 - 4:21it only takes one square meter in this sort of building.
-
4:21 - 4:28So in order to feed 100,000 citizens,
it would only take a plant production unit -
4:28 - 4:34the size of 100 times 100 meters, in 10 layers.
-
4:34 - 4:40And if you take a closer look at the production unit,
this way of producing -
4:40 - 4:43enables us to be totally secure and safe.
-
4:43 - 4:46Without changing anything about the genetics,
-
4:46 - 4:50but just by optimizing the environment
where plants are living, -
4:50 - 4:53we can make them more beautiful
and even more nutritious. -
4:53 - 4:58And we can secure a very great taste,
much better than we were used to. -
4:58 - 5:04We are able to improve the yields
by two, three times the best greenhouse. -
5:04 - 5:08And even 30-40 times compared to the open field.
And very important, -
5:08 - 5:13we are able to save at least 90 % on the water use.
-
5:13 - 5:19The big gift to us was that we never had
any pests or diseases. -
5:19 - 5:25So it appears to be true that
when plants are very happy, they never get ill. -
5:25 - 5:28They are not susceptible to pests and diseases,
-
5:28 - 5:30so we don't use any pesticides.
-
5:30 - 5:35That also solves the fourth misconception:
-
5:35 - 5:40Growing food is done horizontally and takes a lot of water and pesticides.
-
5:40 - 5:45It's not true. We are able to grow any crop.
-
5:45 - 5:51It doesn't matter if it's tomatoes,
lettuce, strawberries, cucumbers. -
5:51 - 5:55We can do anything ‑‑ even medicines ‑‑
medical herbs, for instance. -
5:55 - 5:58This is how it looks like.
-
5:58 - 6:01(Music)
-
6:01 - 6:03This is, of course, the image.
-
6:03 - 6:08And this is a plant production unit
that we have built over two years ago. -
6:08 - 6:14And it's up and running now 24/7
for more than 100 weeks. -
6:14 - 6:18It works perfectly
and we are able to control these units long distance, -
6:18 - 6:23by uploading growing recipes automatically.
-
6:23 - 6:28Those growing recipes
take care of every minute set point -
6:28 - 6:33to grow perfect lettuce, perfect tomatoes,
and even guaranteeing -
6:33 - 6:36that the nitrate content of that lettuce is very low.
-
6:36 - 6:40As you see, they are really green
when they come out. -
6:48 - 6:53The fifth misconception is that food must grow
where nature is kind to it, -
6:53 - 6:58and then we transport it.
That's why we grow 10,000 hectares of tomatoes -
6:58 - 7:03in the south of Spain
and then we transport these tomatoes to Moscow, -
7:03 - 7:06for instance. We have to harvest them five days prior
-
7:06 - 7:08to the consumption moment.
-
7:08 - 7:10Otherwise, they wouldn't be able to be transported.
-
7:10 - 7:13But that is very bad for taste and nutrition.
-
7:13 - 7:18So we want to grow them just where we live,
where the consumers are. -
7:18 - 7:22We want to change foodmiles into foodsteps.
-
7:22 - 7:26We want to go back to the old concept
where we consume food -
7:26 - 7:30that is just harvested. That makes a lot of difference.
-
7:30 - 7:35In this system, we are able
to harvest exactly at the right moment, -
7:35 - 7:38in the right quantity, meaning we have no waste.
-
7:38 - 7:43And we can do this no matter what climate,
no matter what season, -
7:43 - 7:48day or night and any place. We can do this in desert,
-
7:48 - 7:52at the polar circle or inside the city.
-
7:52 - 7:57Then there is a sixth misconception:
food must be grown large scale. -
7:57 - 8:01That's not true either.
We could do it in the center of cities -
8:01 - 8:04or even at the fresh department of your supermarket.
-
8:04 - 8:09Or growing lettuce or herbs inside your restaurant.
-
8:09 - 8:15Or even smaller, you grow your own herbs
in your kitchen -
8:15 - 8:19or you pick your tomatoes from your kitchen drawer.
-
8:19 - 8:23Then the last, and seventh, misconception.
-
8:23 - 8:27It will take years before this is going to happen.
-
8:27 - 8:33That's not true. We are totally ready
to do this, actually, today. -
8:33 - 8:36Within the coming one, two years,
-
8:36 - 8:39we will start rolling out this concept.
-
8:39 - 8:44Especially in Asia, China, India, Africa, etcetera.
-
8:44 - 8:48Indoor farming is the next generation of growing
-
8:48 - 8:51and we are totally there to do it today.
-
8:51 - 8:53Thank you very much.
-
8:53 - 8:56(Applause)

- Indoor planting - Gertjan Meeuws at TEDxBrainport
- Description:
-
Gertjan says we are using too much land, too much water, too much pesticides and too much transportation to deliver fresh food. He is managing partner of PlantLab, where he and his partners are not looking for improving the existing supply chain, but for creating a totally new and better one, based on their invention: Plant Paradise.
