In this southern corner of the Netherlands, a grain of Ember day looks like the last place you’d expect to see a revolution in food.
But in these vast greenhouses,things are happening that could change lives half a world away.
Usually, it takes huge amounts of water to grow tomatoes, but here they’re reduced virtually nothing and they even grow the fruit in insulation material rather than soil.
We use only rainwater and a recycled water.
And you could do this with any vegetable?
Yeah, you can. It can be a solution to to bring food into other places in the world where there’s a problem now.
The tiny Netherlands is already the world’s largest exporter of tomatoes.
This though has an application not for western supermarkets,but for the world’s hungry.
What they’re onto here is regarded as really exciting,because if you can grow vegetables with no soil and with almost no water, then you can grow them anywhere.
You can grow them in the desert or where there’s been drought. And so there’s a growing realization that this technology could be used to fight famine.
The combination of population growth and climate change are making a terrible situation in parts of the world even worse.
And desertification of agricultural land is turning many into climate refugees.
At this leading university,they’re finding yet more radical solutions like extracting the bacteria from plants which can cope in the deserts and putting them into crops.
Incredibly,the scientists believe the deserts of the world are a huge agricultural opportunity.
They think there are two years away from planting crops in the sand.
