think tech, as our documentary series founders valley codes africa to meet the founders, empowering their continent through digital innovation. to transform on work and living conditions in their country and inspiring the world with their ideas. only valley africa watch now 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 widespread crop failures. around 17000000 people, roughly a 3rd of the population live below the poverty line. annie and ezekiel have got a job to do. armed with charlie, they comb through the cities garbage looking for cardboard plastic and anything else they can sell at a recycling plant. here in argentina, cut on and off,

named after the spanish word for cardboard, or a common site. 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 devastating the high inflation means they can barely make ends meet that are almost we work every day and now twice as much. but again, one south full used to be enough to buy food and but now we need to it's summer time and scorching hot on the streets of 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 wise them where it was bomb for the soul wanting forget inflation to get politics, at least now we've got 3 stars. i will get that. we know that it gives us height yet if you fight, you can win and we're 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 sac or anything though. yeah, it does. we just got lucky. what so much in one place, a stroke of luck, i'm are abby's him or is what visit the coll can't carry more than 100 kilos. of extra weight, the sac, the as

a careless securing on the roof will on them the equivalent of about 15 euros. that we get $42.00 is a poor neighborhood with a high crime rate. it's where 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 soccer. legend and giddy came out of the number to fall. i said, married zona, wherever you are div something's waterfalls. and as your hunger booked, your body, whatever. hello, just don't let them full. and it was actually wanted you were talking about the sacks of full. that now comes the hard part. soaking 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 off of one of the per terror circuits is the cradle of argentinian football. it's way play as cut that teeth and when many a discovered la, 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? well another baking hot day, infinity to any. 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, i'm going to have a lot of people don't realize what hard work this is about. they think we're lay abouts, if they don't see what we do as work, but it is several. and now 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 optimistic to get you cause begin. also only some players are still so

young, but they are well champions. sure thing. why shouldn't my dreams come true? he all my life is hard, but i've got a goal m. c. football. i have children, grandchildren, neighbors, 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. often today 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 mercy 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. architects gloria pivots her and her team from the n. g o e. k. allow me are rebuilding the houses. the new ones are

affordable and more durable. something we're here to implement our sink aluminum structure, which is by a retarded. i am in flood flood. we. we went on into ruins. i have no idea. why is this one survived? 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 maze old corrugated iron hut 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 already your brother quoted. this is what we got here. 9. very beautiful. oh,

it is our shower there. fund there. love really? sure we're here we go. we're come. i listen. oh i conway that is room. yeah, i for one room push or one shack room. and you know, that king must or more like falling down with a wrinkle, or would an overhead diction or get the rain gone through that budget time. but now you live in the beautiful place. my gosh, i don't think to go. 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 with we pre finance as much as we can of the bulls and the employee employees 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. there is 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. summer's, or hotter the winds. significantly more ferocious or the sketch and always had heavy winds. for now they, they're more sustained and more unpredictable and often much more volatile. and

even the in migration of people who are moving from the room in into the cities is pushed by the fact that sustainability and so by the ability 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 impalas shock pilot project has already billed more than 70 units. the last ones will be handed over to their new owners to day kept towns deputy maya has arrived. the city council wants to officially honor the new homes and their own. s. thank you. good back. what? oh, small future law expects. it's an important what makes the whole, right. so it makes the home that it does. are you taking friday and you know, your essence to credible and is currently we have

a population sitting at just about 4800000 people. the data suggested rules are, paul's will come close to 6000000 people. at the end of this decade. we need to plan differently with the going for friday, every near to secure partnerships to respond to the housing revenue. i mean, it's a good place to store 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 project also plans to provide solar power for the neighborhood. looking at a 3 megawatts of solar energy production in the kweisi 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 ami, a still to scarce in south africa where they're desperately needed. people like

nausicaa leeway can't wait for years for a safe place to live. the nice thing that won't get. i'm devastated colored wood. that was my 1st fire and i haven't been sleeping well since my neighbors say that is a big fire every summer. it's become normal here. what was the good times? in the last 3 years, fires and kate towns, informal settlements, have nearly doubled to 5000 a year. in super 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 hacked as 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 that. 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 to see

what happens to soils when microbes, the out of whack. we can look back to the 1930s in the united states. settlers replace native grasses with farm let 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 bowl. although farming methods have changed, somewhat soil degradation is still a global problem. what we are doing basically is destroying the soil and now not renewable restored once we have been doing so 5 years in the last 2 and the navy, ease you out at 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 are all this under our feet as top soil or most of the insects and micros live along with plant roots and small animals. one gram of this can contain millions of micros and a few worms, healthy soil have a diversity of microbes. the most common ones are bacteria and fungus. one of their most important jobs is transforming nutrients. every single nutrients, thoughtful on the planet, mostly driven by microscope, none of these cycle that really exists in a vacuum. they all interlinked, one of those nutrients cycles, as with carbon, plants and animals,

i mean mostly carbon. and when they die, they're broken down my, my groups, no microbes, no decomposition. 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 as 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 are very fine routes called hifi. the intertwined themselves with the roots at the plant. the fungus is really good at releasing things like spots for a site from flow,

which is the plan to get it. so it does the end 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 in ur, 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. boil community health is actually the foundation of all persistence, 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. you know, tell agriculture, leave soil undisturbed which allows the microbes living inside the clamps to thrive . specifically those fund guy, high fee which are important for soil structure. there can be

a kilometer of them and a grams. oil. 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. if you can do it from best take you to work the ones that the ball room, the vast amount of areas where the for me. so this grady that these mix on multi now you recover the soil in due time. here's your microbes come in, a larger scale. the most common use is bio fertilizers. they're used like chemical base fertilizer if they contain fund guy or bacteria. soil degredation is a big enough threat that bear a company known for selling i would cultural chemicals is also interested in more countries by the end of this certainly be

certainly held to review. chemical devices to 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. and the micro biome we sees something we'd, we'd really have to, to taking concentration, especially a league final jain because they spread faster and they are more easy, sheeny sank. even bare agrees. just

oh, it doesn't necessarily need an automated heat o. 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 govern soils, and we see the cheapest way to do recovery because we are covering them while we 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. 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 its environment cuisine. one specialty can be found by whom to suit those ticklish that bloom here 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. you can mix them, which trim does that eggs to make the filling will talk of
