and they share private sorties with us that has never been seen before. back channel starts people 20 year olds on g.w. . or. is this what the future of agriculture looks like vegetables and lettuce to start on several floors artificially let. fully automated farming ritesh from trout crossed in stride. this isn't a futuristic question. in japan this is already the reality. for a large cup in the system we can produce food and not optimal conditions with high nutritional content and good taste of the iraq war diligently balance the big

difference to working in the field of people back to. working the fields in brandenburg these thick dust clouds are due to the drought. without massive artificial eric ation there would be no harvest are these fields facing an imminent collapse. under the bridges the conditions are currently i would have to recommend my children look for a different profession. devastating drought here heavy flooding elsewhere. food production is in danger and catastrophic famines wreak havoc throughout the world researchers are searching for solutions. a tip. harvest in japan. the workers were protective suits that are hygenic leaper

care. the environment is clinical these lettuce heads are cultivated without soil and free of pesticides. in this room the temperature always remains the same. is that although i find it pretty good that i can always work indoors regardless of the weather it's ranter than in the rice fields. vertical farming is the name of this method from japan as seen here at the company spread and cure to the roots thrive and the liquid nutrients from the ocean without topsoil but with the same natural ingredients such as sodium and potassium . lamps with a similar color temperature to sunlight are used. solar collectors and the building's green facade indicate that progress is that home here. the university of chiba in japan. and this futuristic looking greenhouse experiments with vertical

vegetable cultivation are being conducted. professor to your key cause i invented this method in the 1970 s. back then he initially had problems finding the right light and had high electricity costs the breakthrough came with the technology you go show you google originally i wanted to help the small farmers who own a small land parcels cheese straight vertical farming enables one to achieve 100 times more annual harvest on a single area than with conventional farming he washed up so it's worth investing in such vegetable factories these facilities can be set up anywhere it's an important step towards sustainable agriculture there are no losses during the harvest and we use less energy for transport productivity and profitability can be increased even further with the latest technology. which. this method is mainly used for fetched to post in salads. as far as staple foods go

such as cereals or potatoes more research is still needed. to know one difficult point will bloom in japan after the cuckoo shima catastrophe there was a lot of interest in these new greenhouses because it is possible to produce all year round regardless of external influences got it from all who could make store methods of the farmers have a stable production without damage from insects or warms this. and of course the system is sustainable when you can run these beds double back trees in the middle of the city and produce local food as needed from the folks who are going to. the contrast agriculture and the fields. once again the farmers like watch are a lot of water and the weather is much too hot temperatures of up to 40 degrees celsius can dry up the soil to 2 metres deep.

large parts of germany are affected by trout in the summer. the results can be the total loss of the harvest was high financial losses. can harden and brandenburg as one of the farmers who suffer he grows potatoes and corn. his farm is located in an area with light dry soil without the help of expensive irrigation systems nothing would grow on his farm. the water already needs to be pumped from deep underground and climate experts predict that even more extreme dry periods are expected. and well if you don't board one called that if you look at the ground here there is no moisture that's no longer can survive by the front. that's why there's not much angles if it's. here are 2 miserable potatoes there are

a few more which might have been ok if they had an awful lot of like last year we are having a very dry year again it's only rained half the amount that we normally would have had at this time of year for solar so dry from last year that even the little rain we've had over the last few days is not enough for the plants because i will be flooded since we are mia. but how can the farmer's problems be solved how can we ensure that food supply in the future is safe. bunning in university in the netherlands is looking into these questions at the renowned agricultural university scientists are working on using new ideas and methods to finally defeat hunger and the 21st century they are working on the assumption that in just 30 years twice as much food will have to be produced as today but the conditions for this have become worse in order not to exacerbate the climate crisis the area available for food

cultivation should not increase new methods are therefore needed to produce food in the future. and funding and as head of the planned science department he understands how grave the situation is. so if we change nothing and we keep all consuming the way we are doing if we don't optimize the way we produce our food then for the next 40 years we will need to produce as much food as we did over the last 8000 years and i think that gives a really good impression how big the challenge is to feed the world in 2050. with its huge greenhouses the netherlands is the 2nd largest food exporter in the world and they take care of their resources. vegetable growers here need much less water to. tomatoes and elsewhere thanks to new eric ation

techniques. our research is focusing on. to produce more food but at the same time to do it with as inputs so we need to produce more nutritious food more safe food and this challenge more with less and better is really the overarching feeling of our research programs. this is how daily life looks in the spanish region of i married. under this sea of plastic tarp and then lies europe's largest special garden. artificially irrigated grown for export. millions of tons of tomatoes peppers cucumbers and other varieties are shipped from here mostly to germany. but intensive cultivation has its price. pesticides and fertilizers contribute to the fact that hardly anything grows here outside the greenhouses. and the spanish french who are farmers are running out of water the whole area is trying out.

the situation in africa is even more extreme especially south of the sahara. the reason an increase and weather catastrophes. it's almost impossible for the poor and hungry to lift themselves out of their misery without external help says the secretary general of german agro action. zeidan yards wide since 2014 the number of hungry people has continued to rise and currently 821000000 people suffer but we can see quite clearly that about 30000000 people have been affected as a direct result of the climate change this claim of hundreds. personally and very acutely affected by this because the storms currently hitting these countries were. previously completely unknown and this is just such

a sign of the destructive force of the changing climate to contribute and how the people in the countries where we walked quite defenseless and at the mercy of the elements all the difference and. catastrophes drought and floods destroying not only the living spaces of inhabitants but also valuable agricultural land. was. also crowded in bourke from recurring harden can solve his trap problems with technical help supported by the e.u. he nevertheless has pessimistic about his future. with legal resources i regain ssion is the only way we can still grow things here you try the grain cultivation is actually not feasible anymore and we are no longer competitive worldwide to be reviewable but tadros that we irrigate are sold here in the region where we still have a market that we can sell to with the recall that we are including. back in japan

at the company spread and kyoto headquarters for the new world of agriculture spread as currently the world's largest farm for vertical production. an employee of the company on her way to work. her clothes are more similar to what people wear and an operating theatre than on an outdoor farm. here hygiene regulations are very strict. all precautions are used to prevent germs from the outside entering the production as the food should be claimed and unspoilt. in this closed sterile environment the plants grow without the use of pesticides and fertilizers. a good $50000.00 heads of lettuce leaves the factory every day this hall is only used for packaging others are used for growing very special post including mushrooms and exotic curbs. the selection is large. none of the producers watched as there are germs in the watcher that may cause the vegetables to spoil

another advantage of this type of indoor farming is that the chance thrive on several floors above each other and each very little valuable floor space the cultivation and some of the house is already fully automatic. she found at the factory 15 years ago you could do the not so good in me fact that climate change or the explosion of the world's population was not a big issue in so doing or was there a market for factory grown vegetables well you may be more but now we make a good profit. i don't think that factories will replace conventional farming completely and book but i think that our way of farming will play a central role in 20 or 30 years ago if we want to share the technology with poor countries so that they can produce their own food or so good you'll stop just. thanks to the short distances to supermarkets and restaurants no goods or spoiled train transports unlike in conventional supply chains. on the other hand

conventional agriculture in japan is also in a deep crisis. farmers use pesticides as a necessary tool and rice cultivation price which is sacred to many japanese is heavily subsidized in japan the market is largely protected by high customs duties price imports are considered an attack on cultural heritage. but the areas under cultivation are dwindling the average size of a japanese farm is just $1.00 hectares which makes it difficult for farmers to make ends meet. that is why there are hardly any young people farming was the average age of a farmer being 66 years old cooperatives are formed in many places in order to be able to far more effectively but the increase in natural disasters is also causing them problems. the war.

to avoid being held hostage by these changes the farmer. was inventive will grow up and this is my aquaponics system he proudly explains and his small greenhouse he is trying out a new form of agriculture aquaponics here fisher bread and large tanks ikea each has 250 starches and his facility. what. the fish excrement is pumped out and used to spread to lies or her various vegetables the water purified by the plants is then returned to the fish tanks. from rice farmer to modern aquaponics farmer almost all vegetables thrive here all year round and are independent of climate changes the greenhouses even withstood an earthquake. the neighboring farmers have already suffered this year it rained too

much and their plants did not get enough sun. i kid out over can still carry his harvest to the market. and dreams of an even bigger plant. such as this one in the show never back to strict in berlin. and the grounds of an old industrial complex greenhouses professional growing in the middle of the city. groups of visitors from all over the world come here to learn about the goings on inside. this is also an aquaponics farm but on a grand scale. the current product capital city. grown with the excrement to fish president these tanks. the fish that is marketed in berlin is of course called capital city perch. with one thought we want to

produce where people consume so we don't have long supply chains or long cold storage time zone and we have a much better c o 2 ballots so it's why i think our fish the capital city perch is the freshest best you can buy here in berlin. the principle as old as the hills the water that is polluted by the fish is extracted and used as manure for the plants and has been used this way for centuries in china and by the mayans of central america. the plants grow faster on shelves are in raised beds in these rooms than in a natural environment the young entrepreneurs produce $1500.00 basil pods per week for a supermarket chain so won't take long before the costs for the 1400000 euro construction are recovered. 7.8000000000 people currently live on our planet in a mere 30 years it will be 11000000 more and more people are leaving the real areas

and according to united nations study 2 thirds of the world's population will be living in cities and 2050. or more of these fires will have to be felt especially and asia. there the mega-cities already extend over huge areas without any agriculture more plants and more greenery is needed and the cities. urban planners face a new challenge the inhabitants of mega-cities not only have to be supplied with living space watcher and energy they also need room for growing food. the district of architects just talking and movement and his staff are planning huge presidential and office complexes and almost all the world's megacities and they need to make them attractive to live in. dallas and. it's we have to deal with

overheated city those cities are significantly warmer and hotter and the surrounding areas are rich for dealing with sitters that are not only dense so to speak but also sealed so no offices there is little contact between the environment and the awful with correspondingly. negative consequences due to the influx of people and of a crowd or by the physical it is no longer possible to ignore this problem with me so the idea of revenge attention and of green architecture equal to a major role in the wheelchair to war from the being in the war for no. this residential and office complex in singapore as high as the president television tower is an example of the descent of architects work. 20000 people live and work here a small town in a single building complex. in the middle of it is it green heart 350 different plans species help to provide better air and a better climate. never think of the room for this is certainly not the solution

for normal rural central european areas it is the solution for high density locations where you know of course if you plan to create a green area you can also use it to produce food so you have to have facts of life you have to shading a factor and the fact that the food is produced here and so you have the benefit of oxygen production about and an additional advantage is that if the project has grown here you also save c o 2 june additional to transport roads what we are going to stop the hands green areas and not just for recreation agricultural producers grain food and high rise buildings or on roofs next to huge office towers just really i wouldn't dismiss it although it does of course aim bizarre because i think that from a central european perspective it's difficult to imagine the density and intensity is one of the difficulties many of these cities will face in the next 50 years

because what comes next is to achieve this with a quality that enables the people to live healthy lives there on a permanent basis for. what sounds like a futuristic dream is already a reality in asia. but also in europe more and more people are moving to the cities and the transport supply chains for food are getting longer. in the center of tokyo dickinson the main shopping street of the metropolis home to the large japanese corporations and long established institutions. a rice field in the middle of it on the roof of a high rise building. a secular brewery grows the raw material for its rice wine here. in japan psyche is not just an alcoholic beverage it is an indispensable part of the country's culture just like rice. which is why sackey and rice belong right

in the heart of tokyo for this program. it is also an experimental field for new varieties the roof of a high rise building as an agricultural alternative. that body. in the beginning they didn't take us seriously no rice would grow here it's much too right here at night with a cut on the roof it's much too hot. but our experiments have been good and we're harvesting more and more the rice grows well here i think it's right that in japan they are looking for different ways to grow rice and vegetables it's a challenge. and after all the rice is part of our tradition let's start back if they're not on. each season the brewery produces 50 particles of sackey from a small rice field on the roof of. the historic building hope in the center of berlin. right next to the museum's

entrance hall as a restaurant. illuminated glass cabinets are not just part of the decor i inside grow harps and salads. and it's really start up based in berlin has placed these plant cabinets in various restaurants in the city as well as in the stores of a supermarket chain they function similarly to the plant factories in japan and ensure that the project is fresh on the table. there are 50 sets many greenhouses and berlin alone and about $200.00 already distributed throughout europe. 2 square meters of space in the plant cabinet corresponds to 250 square meters of regular farmland and this food is wasted in the kitchen because you only harvest what is necessary for the dishes that guests have ordered their off the stage from our farms 2 or 3 times

a week we don't have to wash up because it doesn't have any dirt it has just water it wants so it's perfect for for the cooking also but i guess this is for example it's true so let's 1st of all it's there does this very hard to get in there in the market so well you can see that it's over 6 feet and the fact that you just you are harvesting it and putting it straight into the plate it makes a huge difference but the other thing and i think this is the most the bottom one is that you have access to the flavors and to plants that you cannot get anywhere for example this one is small stuff and it's something that you cannot get in the market and things to really like must stop the cycle it's sharp and spicy. admittedly this kind of special preparation is more for the enjoyment of a metropolitan minority presently these greenhouses are not your plan for mass

production in germany. at least the lettuce here doesn't travel far to be put on the table. factory plans grown under artificial sunlight without earth and with little watch or. an important step for the nutrition of the future and the challenge for conventional agriculture. real will work with nature if you look around here marx are singing the insects are flying around but that isn't the case in these facilities i believe that this is not what you want in the future it's not nature it's just an artificial product i just can't imagine it but it has nothing to do with my ego's as a farmer who in the army for me farming is having an area of land here where something is growing that i can take care of what artificial farming goes against the philosophy of what i want to represent with my soul as a farmer. but do we have another choice classical agriculture alone will

not be able to supply the growing world population without the help from the oratory for much longer with plants that develop in a controlled way without the use of fertilizers and pesticides and with less water . so you know we'll be a world population of 10 or 11000000000 people we can't imagine how big the cities will become and at the moment it's almost considered progress if you can successfully cope with overcrowding at all it is an essential part of 21st century technology then we achieve this because if we don't all survival on the planet may not happen what do you want do you want to produce is such a way that you have. and you use you need to use a bigger surface and that means that you have to destroy nature or you want to have your. square meter so my opinion. is that we use our agriculture fields in such

a way that we optimize the growth in order to save the environment. our research is still just starting however in the coming decades cities throughout the world will need to host critical agricultural safe clean and sustainable prides. if we are to prevent the food from becoming scarce. complete.
