as our documentary series sanders valley africa to meet the founders in poland. they're continent through digital innovation transformer, work at home and living conditions in their country and inspiring world with their ideas. only valley africa watching out of w documentary. ah ah, welcome to global 3000 nourishing earth. why fertile soils the key to feeding our growing global population better housing?

how are africa's cities tackling the challenges of rapid growth and poverty in the land of the champions? how people in argentina coping with a long running crisis comparing prices, hunting for bargains in markets and supermarkets, food is an expensive commodity in argentina, prices, they're almost doubled over the course of a year. for years the country has been mired in economic crisis. on top of this long running droughts have led to wide spread crop failures. around 17000000 people, roughly a 3rd of the population live below the poverty line. annie and as zekiel have got a job to do armed with a charlie, they comb through the cities garbage looking for cardboard plastic and anything else they can sell at a recycling plant. here in argentina,

katanas named after the spanish word for cardboard, are a common sight. i'm getting your hands dirty, making an honest living. that's what we teach. our kids money was always tight for the couple. and now devastatingly high, inflation means they can barely make ends meet to look like almost we work every day and now twice as much. but again, one southfield used to be enough to buy food, but now we need to it's summer time and scorching hot on the streets and when osiris, but the world cup gave the country a much needed breath of fresh air. the national football team's triumph in december was an excuse for a party that lasted 3 days. ah, argentina has always been so crazy. but the world cup, when unleashed an unprecedented wave of nationwide euphoria,

after the relentless onslaught of bad news, the financial crisis spiraling inflation and the pandemic, there was finally something to celebrate and provide encouragement wide some where it was bomb for the soul. wanting forget inflation to get politics. at least now we've got 3 stars. i will get. i will know that it gives us hope jack. if you fight, you can win and why fighting? our team fought 2 and one. just let you go, jonathan. meaning i don't it doesn't take long to fill up the sack up a little bit ago. yeah, it does. we just got lucky. what so much in one place, a stroke of luck, i'm are abby's him or what visit the ca can't carry more than $100.00 kilos of extra weight. the sack, the as a jealous,

securing on the roof will on them the equivalent of about 15 years. that we get feared, ito is a poor neighborhood with a high crime rate it sway diego merit donna grew up afloat. hero of the people. a boy from the slums who rose to super stardom who made mistakes but stood unconditional love in his legions of fans. in the well cup final, when it looked like argentina might be defeated, annie turned to the late great silken legend and giddy, came out of the number to fall. i said married zona, wherever you are div something's waterfalls and does your hunger hooked your body, whatever. hello, just don't let them full in it. well, that's what you want to do. we'll hope you brought the sacks of full. that now comes the hard part. salting out the garbage. they'll be working well into the night. many of argentina's top footballers come from

poor neighborhoods. the game is an escape from poverty. when darkness fully of crowns gather to watch unofficial football tournaments as quite a bit of cash at stake at the semi legal events known as portray ross. it's how franken and his living through betting that to the idaho when i used to work and play but iron much better now than with a normal jaw. and almost i got an awful one in the per terror circuits is the cradle of argentinian football. it's where play is cut that teeth and when many a discovered ally, the cunning, the daring, the, this is where the best player start out with this matches on fire. frank, who was once approached by a tenant scout to but didn't have what it takes to go professional. he owns enough

. he had to take care of his son and survived the financial crisis. franco is a local legend, but his income isn't secure. very well. we lost that he screwed us, doesn't matter when he comes, goes and we wanted to win, but this time we didn't know it on the was it will another baking hot day in futile annie and as that yell are exhausted, they were up separating rubbish until 3 in the morning, but there's no time to rest. they need every pest. so i will, i'm going to have a lot of people don't realize what hard work this is about. they think we're lay abouts. they don't see what we do as work, but it, it said, well, i know i have to fix this to them. they're about to head for the recycling yon to see how much they can get for that concord. despite the odds they're up to mistake . forget you called me and also some players are still so young,

but they're well champions. josie, why shouldn't my dreams come true? he all my life is hard, but i've got a goal. hm. see for bye. i have children, grandchildren, neighbors, you, anything's possible to see if with a life these days is harder than ever. but as a kellen annie aren't the kind to complain. ah, to day about 1000000000 people live in africa, south of the sahara and says the u. n. that numbers set to double by mid century. in a few years, most africans will also live in urban areas. partly because many people in rural areas are moving there in the hope of a better life. the boom is also fueling a housing crisis. today about half of africa's urban population south of the sahara live in informal settlements. this poses a major challenge for growing cities. as this report from south africa's cape town

shows. the township of muscle who millennia cape town has 30000 residents spread across nearly 40 hector's nose locally. where is sorting through the wreckage of her home. 2 weeks ago, a fire destroyed 178 shacks. here homes made of corrugated metal on a wooden frame, sol, so i ran out without knowing what the only thing i have left in my pajamas was my neighbor died in the fire. one of her friends filmed the inferno fires like these are happening more frequently. as the population grows, people are living closer together and heat waves are also more common because of climate change. dozens of homes also burned down recently in cape towns biggest township calisha and not for the 1st time architect, gloria po veto, and her team from the n. g o e k. allow me our rebuilding the houses in the new

ones are affordable and more durable. something we're here to implement, i think aluminum structure which is why retarded them are talking about m. n flood flood. we we one on into ribbons are player by is this one survive the latest fire without a trace, the sheet metal they're using as thick her. so fire can't spread as easily from home to home. economy is funded through donations. it's already billed 3500 of these new models. in the closer language economy means my home. the n g o wants to help people live in safety and dignity. cedric mays, old corrugated iron heart was replaced a year ago to her long who like to see how things are going. yeah, everything is okay. and her, as you can see, the place of rigor nearby this quoted was, is roughly about yes, 9 very uniform. but if i was our fund

love very surely. we're here we go. we're come by. listen. oh i conway that is room . yeah. for one room push or one shack room. and you know that king must or more like falling down with the wind. come with an overhead diction audit. lorraine gone through that project on, but now you live in the beautiful place. my gosh, i don't yet thanks. forgot. cedric may works as a caddy on a golf course. his employ agreed to help finance the construction cost of the round $1000.00 euros together with economy. this kind of co financing is the basis of economies funding model almost live a difficult we pre finance as much as we can of the bulls and the employee employers meet us half way. and sometimes employees also partake in that in that perhaps the employer can pay up front and in the employees pay back the employer um

at a rate that suitable to their relationship and their financial reality. the golf course paid back their interest free loan within a year economies housing initiative as part of the project by it collaboration. it helps employers provide they work is with a better home for the equivalent of about 70 euros a month. these huge demand in formal settlements will dominate africa, cities in the near future. they already home to one in 5 cape town, residence joe ball. nick is an urban development advisor. he says fine resistant homes can quickly improve living conditions and townships in times of climate change. summers are hotter the windsor, significantly more ferocious or the sketch and always had heavy winds. but now they, they're more sustained and more unpredictable and often much more volatile. and even the in migration of people removing from the room,

enters into the cities is pushed by the fact that sustainability and survivability in the rural areas is being profoundly impacted by the changes in crime economy isn't only making homes fire resistant together with the urban think tank from e t h 0. the n t o has replaced an entire informal settlement with 2 story homes. the and palace shack pilot project has already built more than 70 units. the last ones will be handed over to their new owners today. cape towns deputy maya has arrived. the city council wants to officially honor the new homes and their own is like a good the backwash. oh so you. so it's it's, it's an important mix. the home who likes the home. it makes the home that he does . but you taking pride in yo yo s, it's incredible and is currently we have

a population sitting at just about $4800000.00 people. the data suggested rules are partial composed to 6000000 people. at the end of this decade, we need to plan differently with the goal for friday, every need to secure partnerships to respond to the housing for money. i mean, it's a good place to start in an emergency. this st provides access for fire trucks and ambulances, where corrugated iron huts one stood, crammed together. they are now children playing. the potters also plans to provide solar power for the neighborhood. looking at a 3 megawatts of solar energy production in quasi park alone. i and see the potential for i think it's about 2 gigawatts of renewable energy production in kylie cha. initiatives like empower shaq and e. kyle army, us still to scarce in south africa where they're desperately needed. people like no zacalo leeway, can't wait for years for

a safe place to live. nice thing that won't get. i'm devastated gully wouldn't. that was my 1st fire and i haven't been sleeping wilson. my neighbors say there's a big fire every summer. it's become normal here. what was the guy punch? in the last 3 years, fires in cape towns, informal settlements have nearly doubled to 5000 a year. in most of whom are lily there, worried that if some is keep getting hotter, this is just the beginning. now how can we feed a world of 10000000000 people by 2050 equitably unsustainably just under 5000000000 hectares of land already being used by agriculture. that's around 37 percent of the global land surface by mid century will need to produce about 60 percent more food to ensure that no one goes hungry. in recent decades,

modern agricultural methods of lead to greater harvests. but it's been at the expense of the soil, in many regions of the world, large areas of arable land and now under threat. and yet a healthy soil is essential for successful harvests and for a healthy planet. right now, these are living on your body. but don't worry, they're supposed to be there, they're microbes and the planet is covered in them. and there are tons of them in the soil because they literally make fertilizer for plants. these are some of the only things on earth that can do this. we depend on soil for almost all of the food that we eat. and because 90 percent of the planet's oil could be degraded by 2050 scientists and even agribusiness think microbes could be key to averting of food crisis. so let's take a journey to the invisible world right under our noses and our feet. me to see

what happens to soils when microbes the out of whack. we can look back to the 19 thirty's in the united states, that there's replace native grasses with farmland and then intensively tilt which killed microbes and degraded soil after a series of droughts. the damage soil was easily picked up by the wind and turn it to so called lack blizzards. millions of tons of tops, well, just blew away in what came to be known as the dust. although farming methods have changed, somewhat soil degradation is still a global problem. what we are doing basically is destroying the soil and now and not renewable for what we have been doing so far in the last 2 and the navy e d u soil out as the strike to grow plan. we've been under valuing them and expecting them to stay healthy, but tilling over using chemicals and climate change are harming our soil. this is

a problem for growing food, as well as resources for clothing and construction. soil is also key to storing carbon and filtering water. to make so else healthy again, we need to start seeing them as what they are. entire ecosystems, teaming with hidden life, all run by my groups. all this under our feet as top soil where most of the insects and microbes live along with plant roots and small animals. one gram of this can contain millions of microbes. and a few worms, healthy soil have a diversity of microbes. the most common ones are bacteria and fungi. one of their most important jobs is transforming nutrients. every single nutrients cycle on the planet, mostly driven by microscope, none of these to cycle that really exist in a vacuum. they all into one of those nutrients cycles. as with carbon, plants and animals are made mostly of carbon. and when they die,

they're broken down my micro no microbes, no d competition. the microbes use some of the carbon to reproduce, storing it in the soil, and be the rest of it out, sending it back to the atmosphere. another nutrient cycle happens with the nitrogen, which makes most of the air around us, and is one of the main nutrients plants used to grow. plants can't get it from the air by themselves, so they partner with microbes. and we can find evidence of the nutrients cycle by looking at certain plants like these beans, which are considered nitrogen, fixing the beans create these little root nodules that become home to a certain type of bacteria. in return, they change nitrogen into a form that plants can access microbes, specifically, fund guy, also exchange other nutrients of plants. they very fine routes called hifi. the intertwined themselves with the roots of the plant. the fungus is really good at releasing things like spots for the site from flow, which is called the plan to get it. so it does that and exchanges that with the

plan in return for things like sugar, which the plant can make tricks. there's also some evidence this relationship makes the plant more able to withstand drought and disease in a degraded soil. these new chain cycles aren't working as well as they could be. climate change is one cause of degrading soils with drought and extreme weather, causing them to dry out in a road intensive. agriculture can be another cause. as pesticides and err, besides kill off beneficial microbes and reduce their activity. the more degraded soil is the more chemicals are needed to grow stuff degrading the soil even further . this whole plot of land was intensively farm for 30 years. and you can really see it in the soil. it's super sandy, dry and degraded. degraded soils also lose their ability to hold and filter water are more susceptible to erosion and have less of those beneficial microbes,

meaning plans don't grow as well. but soil health is about more than just our food security. boyle community health is actually the foundation of all acre system, but natural and man. if the nation of something crumble, everything else comes tumbling down and agriculture might actually hold the key to making our soils healthy. again. the same plot of land, not so far from the degraded bit years of regenerative agriculture have brought back a lot of microbial activity. the soil looks completely different. this farm is a best practice example. no chemicals are used and the soil microbes, arthur riving. just look how beautiful these 2 meters are. know, tell agriculture, lead soil, undisturbed, which allows the microbes living inside the clamps to thrive. specifically those fund guy, high feet, which are important for soil structure that can be a kilometer of them and a grams,

soil and cover crops planted to leave in the ground. right? micros of carbon to chow, down on as well as producer rosen and nutrient las unfortunately, this kind of farming just isn't possible everywhere. you can do it from best thinking of what we want. but the ball room is the fast, the mountain areas where the ball and the so the grady that these techniques on the now to recover the soil in due time. here's microbes come in a larger scale. the most common uses, bio fertilizers. they used like chemical base fertilizer if they contain fund guy or bacteria. soil degradation is a big enough threat that bear a company known personally, i will. cultural chemicals is also interested in, in the countries by a good alternative is certainly we need

help to review kevin for the company is also investing in seeds that have been infused with microsoft because delivering microbes along with seeds is the most targeted way to apply them. seats can also be planted with a coating of microbes, conservation organizations are using this approach to restore ecosystem. a problem with commercial microbial products is that the microbes are not specifically adapted to environment. non native microbes could find it hard to survive, rendering the process useless. and because these are living organisms, they could cause an imbalance in the micro biome. we sees something we, we really have to do taking concentration, ashery, li, file jain because they spread faster and they are more easy. shinji sank. even bare agrees. oh,

it doesn't necessarily need a automatically oh, since soils are different around the world, we would ideally develop microbial products for specific regions. but that will take time and more research. unfortunately, our soil health is an emergency. we are going to movies because we actually cover soils and we see the cheapest way to do recovery because we are covering them while we are, are maintaining the ged to for large farms, bio fertilizers are a step above chemicals and where possible. agriculture that relies on helping native my groups like on this farm is the way to go. all reposes have been tracking down tasty snacks again. this time in indonesia, ah shimoda on a multicultural port city on the north coast of java has been shaped by european

chinese arabic and japanese cultures. and that's reflected in it's vide cuisine. one specialty can be found by him to see those ticklish, that lumpy is a kind of sweet or see re spring roll trees. look, p o version was created, went on to him who said those chinese grandfather and in bernisha grandmother combined their recipes more than 100 years ago. now their grandson runs a snack bar and is sharing the olympia recipe with us. all the room argue that we washing cook the bamboo shoots into their soft at home. then we bring them here and mix them. which trim does that eggs to make the filling? will you talk with it all goes into

a large walk where it's quickly stirred and fried then the mixture is spread onto a length of go. now they have to work quickly. it's very popular with guests. with produce 500 loopy, on weekdays, and twice as many on holidays where i'm a lumpy, are served fresh or friday. the price stays the same with before the corona virus pandemic customers used to line up at the stand and eat right here. the look p a was served with a save re coconut sauce. ah, today the lumpy spring rows are only sold impractical to go boxes. a lot of

us let i know every time i go to simmering. i have some of these lumpy. it's famous, a legend to young and the doctor now, and that is just a legendary snack with a long tradition. and that is a little from us that global 3000 dis, thank you. thanks for joining us. we'd love to hear from you. so right to us at global 3000 at d, w dot com and come and find us on face that j. d. w global ideas. see you next time and until then, take kath, ah ah, [000:00:00;00]

with my car is made in germany for decades. they were a symbol of excellence and reliability with what they are glamorous image is getting its blemishes are cost cutting measures and

a focus on efficiency affecting quality german cars. when will they lose their sterling reputation? read it on d. w with one a winning offer. he's available worldwide and for every language level, learning german has never been simpler. german to go. jeremy has had 1111, not a single one. mission is then the 1st female jam. israel has

the gender gap in space exploration. germany's 1st female astronaut. it has been waiting for years to get her turn. a private initiative is pushing to make it happen. me personally. it's just a dream. i was sad. i've always wanted to see the us for destiny for space starts more changed on d w. so i was just rescuing the dog from a farm. this one this body go with i found it like this and i couldn't just leave it there. should. 2 2 2 be this is such a great bird with it was so dirty that cleaning it, turn the entire bathroom into a mess. this is the water birds 1st. well, one of the most beautiful moments i've ever experienced with

w series about our complex relationship with animals. well, i think i will live long enough to witness the factory farming the great debate this week on d. w or ah ah, this is dw news. why? but from berlin? tit for tat violence in the west bank and israeli man has been killed in a new shooting. it follows attacks by israeli settlers that left one palestinian man dead. and that violence came after 2 israeli settlers were shot dead on sunday
