How To Feed 10 Billion People

By 2050, there are going to be almost 10 billion of us
living on this planet. And all of us will need food to survive. If we don’t change
anything and we will go on in the way we are now consuming our food, then the next 40 years, we need to produce as much food as we did over the last 8,000 years. And that’s a huge challenge. Agriculture is the largest source of non-CO2 greenhouse gas emissions. And, along with climate
change and urbanization, the resources that we
need to feed everyone, things like space and water, are becoming harder to find. That’s why scientists and
farmers across the world are finding new ways to help
us and our planet thrive. So you’re now in the central area of the Netherlands. And within this area we have
many different institutes and industries that are focusing on the big challenges in food. We like to study things in nature, try to learn from things in nature, and try to transfer this into solutions that can improve the quality
of life of humankind. Wageningen University is known as the Silicon Valley of agriculture. Students and researchers
from more than 100 countries work here in vast greenhouses and labs to determine the future of our
food and how we’ll grow it. The Green Revolution in the 20th century started by a guy named Borlaug and he was a plant breeder. And what I like about the story is that the guy got the
Nobel Prize for Peace. Not for science, but for peace. And the reason was that he came up with new cultivars of wheat that were able to produce more per plant. And, in that way, he
could offer a solution for the hunger that was quite important at that time in Asia and in Africa. The bad thing was, of course,
that these new cultivars also needed a lot of fertilizers, a lot of pesticides. And that’s the reason
why I think that we need a new Green Revolution. We need to produce more per square meter, but at the same time we need to use less fertilizer,
less energy, less water. So, more with less and better is really a summary of
our research programs. Along with the driverless tractors and agroforestry being developed here at the university’s research farm, the next Green Revolution
could rely on optimizing the most fundamental process
in every plant, photosynthesis. All life depends, now, on photosynthesis. So, it’s an essential
building block of life. For a long time, people thought this could
not be changed anymore. They thought this is a fixed thing. It already exist for
about 2 billion years, so very long time, and people thought the evolution would have taken care of this. And now it looks like it’s not. The team created a robot
filled with cameras that can image plants
while they photosynthesize using a property called
chlorophyll fluorescence. By examining photosynthesis
at the DNA level, they identified natural genetic variations in the way plants handle light. That data can be used to breed crops which are almost 50%
better at the process. Not only could that double yields, but the optimized plants
will be more efficient with resources like water
and nutrients in the soil. So, what the Green Revolution taught us how by changing the
architecture of plants, we could harvest more of the plant and that’s probably saved
humanity from a lot of trouble. Now, this new step in
looking at photosynthesis could mean the same. So, if we can improve with only a few
percentages photosynthesis, we would also be able to
improve plant productivity. And if you can do that in a
sustainable and durable way for a long time and making it
available to a lot of people, by just increasing one trait, then would give us a
tremendous boost forwards. On the other side of the world in China, improving food production to
feed its 1.4 billion people is already an urgent problem. This small-scale peasant economy means lower production at a higher cost. And, combined with food safety and sustainability challenges,
this creates major problems for the country’s agriculture industry. Dr. Li Shaohua is the research director at Sanan Sino-Science,
a joint venture between the Chinese Academy of
Science and a local LED maker. In 2016, they built this factory made up of eight three-story buildings to grow medicinal plants and vegetables. This one building covers
just under an acre of land but provides 1.8 tons of
produce every single day. Their secret? A modular planting system made up of one-meter square boards which contain lighting and
storage for a nutrient solution. The boards easily slot together and can be replaced quickly if they break. There’s no need for pesticides and the cooling system
recycles evaporated water back to the plants so that some use over 18 times less than if they were grown in a field. For now, most of the vegetables are sold to local supermarkets
across Fujian Province and one bag of lettuce costs 11 times more than others on the shelf. But the price is likely to get lower as the technology becomes more widespread. Solving problems in food production will also mean that you are
working on solving issues that affects the whole Earth. It’s a combination of feeling responsible for the environment and feeling responsible for
feeding the growing population.


  1. Dont worry,since there are many kind of people who wasting food without feeling guilty,in the name of art.just lik-

  2. Reasons like this is why I can't stand when people waste food or "food" decorations. Just a look around youtube and you can see dumb people using food as pranks, challenges, etc.

  3. I still don't get it at this point why instead of looking how to feed 10 billion in 50 years, look for HOW NOT TO GET TO 10 BILLION STARTING NOW!!!!!! are we blind? or we turn our head to pretend that overpopulation is not upon us NOW!!

    Sigo sin entender por que a estas alturas en lugar de ver como alimentar a 10 billones en 50 años, buscar COMO NO LLEGAR A 10 BILLONES EMPEZANDO YA!! estamos ciegos? o desviamos la vista para pretender que la sobre-población no esta sobre nosotros YA!!

  4. Why they looking for technology that required less man power ? less jobs = people won’t have money to buy food

  5. this is a business MOVE pushed by companies in excuse to make more money nothing more….there are lots of fresh foods thrown from supermarkets everyday because they remain in shelves…even in china! its just business

  6. If their needs of foods are fulfilled then the peace will be come cause there's nothing would make humans fight no more.

  7. If the government's around the world dont start purging the population then were gonna start seeing wars over food control

  8. Community gardens would be great to start everything up but people are lazy, selfish, stuck in their lives, and are not comprehending how serious this is.
    Just stop having babies and stop watering your lawn every damn day. Make your showers 2-5 minutes shorter use hand sanitizer fuck idk just try as an individual to make changes while also alerting others of possible changes to make to help everyone.

  9. Lotta people think population control is a solution. We have 30 years for our population to produce the next 2 billion people. Yes, additional supply is an issue, no doubt. But, those 2 billion people are our future innovators, laborers, scientists, consumers, and entrepeneurs making this technology ever more possible. People are the solution, not necessarily the problem.

  10. I have started jack fruit trees on my property.
    The biggest fruit on earth.
    Doesn't require pesticides.
    Produces 2 crops per year.
    1000 lbs per tree.
    Drought resistant.
    I have seen it go 6 months without a drop of water.

  11. Inspirational. Of the 10 billion, some will also be innovators, creators, farmers who'll make Agri more sustainable & better yield. Post 2055, world population will plunge, never to be back to peak.

  12. That we lack resources for food is the biggest myth. I support growing food vertically and in ways that are space-efficient. This said, We DON'T lack for food or even the ability to produce food in a more space-efficient way; we waste more food than there are people actually hungry. If we adopt a zero waste to landfill policy and as consumers we find ways to eat misshapen tomatoes that aren't perfect cookie cutter veggies we could actually tackle how to feed billions of people. (Reduce Food Waste, Grow in Efficient Spaces, Smarter Usage of Water)

  13. Solutions are lazy. All you are doing is prolonging the inevitable. The extra food will just help sustain a larger population. That larger population will eventually reach the ceiling of agriculture and face starvation. Stop relying on innovation to enable your unsustainable lifestyle, and reduce.

  14. salad wont be able to feed 10 billion people, you need cereal grains, legumes and other high calorie food for that.

  15. Richer countries see declines in population. That is truly why we shouldn't focus on anything but investing in 3rd world countries. It is the most efficient way of doing quick change. Hell, if you want sustainability then invest in sustainable production in those 3rd world countries. Vertical farming is a nice idea, but it isnt cost efficient. It is surely an endgame solution but for now we should focus on bang for buck. It does feel a bit like most policies today are for show.

  16. In the 1700s they said we would never be able to feed 1 billion people. In the 50’s they said we would never be able to feed 4 billion. Here we are today, almost 8 billion and famine has disappeared outside of war zones. Humans are smart, and humanity will innovate itself out of problems, just how we always have. We are doing to today with climate change, we will do it tomorrow with food.

  17. My country has a lot of agricultural lands, but there is not enough technology in it yet, farmers can sometimes go out of business or sometimes lose value on products that cost a lot of capital. This made them decide to sell their farmland. These are very worrying that in the future the country will face a shortage of agricultural land.

  18. How to Feed 10 Billion People??
    Make the supermarkets NOT throw half of their (still perfectly edible) food every week.

  19. There's also a lab in the Weizmann Institute that works on improving photosynthesis. Specifically, making it faster.

  20. BismillahirRahmanirRahim

    The best answer is only greening desert for food forest using permaculture tehnik.

  21. Yeah, but im not a machine, I want to enjoy my food and not just eat grass, I want to eat like a human and enjoy life.

  22. America is the only nation that has the extra capacity to feed the world ,but we like $$$$$ for our produce!

  23. Bullshit. It's you sick bastards not telling people they can grow their own food and stealing their right to grow their own food and stealing all the heirloom seeds and storing them in Antarctica and replacing them with Monsanto seeds forcing everyone to pay every year… Sick bastards.

  24. All people should stop making babies, or may be just one baby. There is no food, water, land and many other resources are inadequate. Why to bring them into the world and cause them suffering?

  25. Food being grown under LED lights with recycled water, people working under LED lights drinking recycled water… sounds healthy…

  26. I think it's going to be fungi that will do the biggest work. gotta stop spraying. gotta keep those fungi alive. gotta keep the soil alive. gotta stop tilling.

  27. I know people will hate on me for saying this, but here it goes anyway:

    -We actually already produce enough food for more than 20 billion people (Not kidding) but most of it goes to feeding animals which we then eat, or some of it in the trash. Which leads to: Waste of food, waste of space, waste of energy, animal agriculture is bad for the environment AND the amount of meat and dairy products the average human consumes is far too much to be considered healthy or natural.
    -I'm not saying everyone should go vegan or whatever, just saying that if a majority of the population cut their meat/dairy consumption by at least half and switched to a more plant-based diet we wouldn't have the problem with lack of food to begin with. (And people would be healthier + have less effect on the environment)

    There you have it, 100% science based facts. But people hate the idea of change so it probably will never happen.

  28. Simple. Stop selling food on a corporate, monetary scale. Stricter regulations on what big box stores can do with edible food that does not sell. Much food waste also occurs at home in the household fridge. A product of gross consumerism. We currently grow enough food to feed 10 billion people. We just need to stop throwing it away and start giving it to the people who want and need to eat it.

  29. i would like people in these plant factories to produce something that actually has high callaries.
    we can not just live on salad.

  30. This is false the population is actually decreasing as more countries are developing there are less needs for multiple children as they wont die the first years of their life. And as more technology is being created and becoming more affordable there is no need for children to help their parents on a family farm

  31. Obviously, the answer is having an EU, European centered Globalist 4th Reich. All problems solved BTW: There's enough food, it's distribution that's the problem including governments that are corrupt or favour one ethnic group over another etc – just say'in

  32. Lets fuck the world to death. Common we are almost there. Finding Nemo;Dory voice: Just keep fucking, Just keep fucking. Quit fucking around.

  33. Maybe endless population growth is not sustainable unless you have endless resources on a finite planet.
    How many fish can you put in a fish tank?

  34. Driverless tractors, isn't that great? Seems smart to squirt out more kids when no one will have a job.
    Neutering these people would solve almost all of the world's current problems.

  35. Ordinary farmers are fkd. Seriously vertical farming is so much more efficient and the part about how it even recycles evaporated water blew my mind.
