time the they are peers and rivals with one daring goals to help smart nature, the more likes watching it. on youtube, dw documentary, the climate change con, jeopardize anti economic sectors and take away people's livelihoods. but in many cases, sub solutions can help us to adapt and opportunities to make life better for roles . welcome to a new edition of a cool africa. i'm present lens, an idea. once again, we're both upon show for you today. let's dive straight to coming up. empowering

goals, how also followed backpack is changing lives a ro, uganda glorious food, city, dwellers, week, steam, pollution crises, we haven't got it installed, proper. got past. we'll meet the woman by, you know, read eco friendly for us collection of recycling in kenya via a smartphone. now, can you imagine catching fish with palm leaves? it's part of an issue and fission methods used of tanisha is kick in the islands called shop the odds, especially in the environment to me frankly come join the also to see how echo offer eco went there to watch these amazing technic of the sea is alika board 2nd time. today he's once again heading out to going fishing, using an angel technique found only here on the kind of items often busy as east

coast. it's cold, sophia, and involves catching fish with the help of palm fronds. almost shortly. for lenny i'm, i've always worked, etc, etc. but when i was a kid, i went fishing with my dad, the unavailable, and when i finished my studies and returned home, my automatically went back to fishing them. each sophia is arranged as a triangular battery. a palm fronds can be seen in the shot, a waters around the occupy, like a fishing technique relies on title comments to drive the fish into the traps. unlike fishing troll is the shot fia don't com, the marine environment. instead they present a bio diversity. they have an active but i think that the, the problem with a drag note says that they don't allow anything to escape with the palm branches, fish, find holes to swim through every hotel and activity that people is friend

. i mean guinea does is also on board. he's not a fisherman, but an artist. and he's fascinated by this ancient fishing technique. traditionally, it involves the use of date, palm branches for guinea, does they to a part of the kind of islands, cultural heritage in his studio, he creates various products to sell using different parts of the palm. this nadine has by the basis of the care, kenny and shot c. a is a cage that inspired me to create decorative objects for indoors and outdoors. i tried to retain the original look how was i that he sees himself as an ambassador official here in 2020 unesco, declare that part of humanity is intangible cultural heritage. it's also linked to angel traditions and cultural practices. walk up on i was using this method as a basis for my project without really knowing how it works. if you,

once i learned more, i fell in love with the c panel. but times have changed. some now use plastic traps is the cheapest. others of abandon the practice altogether. is time consuming. and industrial fishing has decimated fish stokes. so the whole and the shelf you as also plummeted. but some fishermen are actively campaigning to preserve the tradition, especially because it works in harmony with nature. and the palm branches get fish somewhere to hide and live. it's an ecological method that preserves and respects the environment and we'll have a valid via this fisherman, the lead shot fia will continue just on the test of time us the fish cool this way, a far superior to the catch from industrial fishing. good. what's the sure brought to assure a live that's why they're considered to be of better quality than those caused by other means. you know, you to put on high quality fish is an important source of income for the occupant

of go on an added draw of a tourist to visit the islands. but for allie, a couple, sophia fishing is more than a trade. it's positive. good can is unique cultural identity that's now at risk of disappearing. well, let's look at the past all our ancestors how to shop to obviously if government, if the view came in, they would build it up over the summer months. it shouldn't them. but today, having a shots here requires significant financial capital and affordable money that many unable or unwilling to invest. and so she fishing continues to dwindle, even though it's so sustainable. that's why climate change poses huge challenges for many economic models. reducing the impact on the environment can also be a business opportunity, generally making a difference. well, also making

a profit without heads to kenya to meet one's very resourceful woman with a vision to promote a secular economy of social enterprise, collect waste, recycle plastic, and the storage safety of them bustler. and it's all done with a mix of old and new technology or an app for trash. entrepreneur teva hygiene e wants to use it to reduce plastic pollution in mombasa, anyone can register to have their plastic waste collected from home. you are able to book waste management services on the go on the mobile application using authorized waste manages. then you are able to trade or do nature plastics and we have full cash incentive. kenya's coastal city is drowning in plastic garbage. it's trashing up the streets and polluting the ocean a year and

a half ago. table hygiene e started her own business because the city wasn't providing adequate sanitation services. one of the major challenges in almost a county is the indigo dump. think of mix plastic, wasting open spaces. she's providing incentives to counter this by paying participants, depending on the type of plastic about one euro for 10 kilos. for business now has 10 full time employees. first they inspect the plastic to make sure it's been properly cleaned and sorted by the apps users, then they weigh it. finally, they shred it with an eco friendly shredder that run solely on muscle power. the startup cells, most of it's collected plastic to businesses who further process it to shreds can be melted and molded into plastic boards, like those they use in their own hand cards. the startup has already collected more than $11000.00 kilos of plastic drink or pilot phase. we've been able to on board more than 1608. use us onto the mobile app in,

in old town in cooperation with my boss, accounting, department of environment and funded waste management. we've been able to collect waste from about 6000 households, one and a half years later today, seeing how successful this project has been filled me with so much joy and pride as smooth and made of plastics. the chaise. physical packets might be handy, but they quickly found in the garbage bin and they don't roles. you know, web special. we chose the journey of such a sashay from the origins that the rule materials it's made from to its ends on the rubbish sheets. we find out why the number of such chase is growing and why that's so lucrative, so businesses and so disastrous for op, trying to find out more d w dot com slash plastic. that's one impressive woman. and we have both to meet and now the basics eco hero comes from uganda. for more than a decade,

a non profit organization has been empowering girls to take control of their lives and become king, make cuz she has developed a small bag with multiple functions to make it easy for girls to go to school each day. us to do the studies when the sun goes down, the young woman eagerly await it, but it's no visit by naples or relatives, shown cousins, the indian i'm would you have an order with the customer the the to sort of technicians installed a sort of more to here a little while ago, now the light bulbs are flickering properly due to the intimate flow of electricity . they have to find out where the problem lies. the job gives them new prospects of

good some money from the, from the system. like to is to them being what says enabled us, that we have really, really a message the this process. so for you to the main, the 1st seal fuels into the main. so that's the, to initiative this. the susan, the tuneful also benefits from solar energy. but in a different way, the 15 year old school go onto the backpack with an integrated community solar panels. it can charge a lamp. this helps the study at night, in turn, the lumpkin load for, for the cell phone. they said that the safety trade may looks like you don't have a dish, the tomb as you see you so. so have me to send my buffalo lease. i'm going to pass my exams the 3 young woman with introduce can think to me, lemme on just

a social, into a premier, from the condom capital compiler, for the experiences with solar energy. my andrea self gets involved when the employees look for plastic bags on the side of the road as the solar backpacks made of recycle plastic carpets is a big problem and compiler. so we try and make a difference in using these recycling these plastic words. i'm showing the community we are coming from very easy to recycle with the the, with the, with us system. after the plastic bags happened, clean their turn into solar backpacks with cute water proof material. on the outside about 20 women i employed for jamila, my and just foundation. they receive about $5.00 but packed, packed, some of the backpacks a sold for more than $20.00, but for women and girls can get them for free. as more than a $1005.00 parts have already been sold for. donated the backpacks,

allow the young woman to be able to disagree sleeping, permanent hygiene supplies to school. many teenage girls would otherwise stay home during that period, causing them to suffer academically. the disease. you must a should to you on the bus to that cause. the problem is the school, so the us to get a better school back to susan. she also has to do work around the house after school. and she's only allowed to study once it's dark out, which would be impossible without the solar lab. the next morning on her way to school for solar lamp in her backpack is recharged. susan has shown improvement, according to a teacher, will also cause

a scientific and environmental subject. she's pleased at the solar backpack is a convincing practical example of plastic recycling. the bugs upfront with smart deals, so it does become impractical. but what use a good grades default is to look for to unemployment, as is so often the case for young women and you kinda and there is another way, goes was tools office a solution, a program set up by social interest for now to me. lemme younger young women, can you see vocational training certificates for supposedly typical meal? okay, patients sure

loan can use uh his personal receipts solar modul training here. now the 22 year old. so the technician started up on business and she has no solve the problem with a flickering lights, all of the cleaning up the solar module enough and tricity is now, so we do it. then after a minor difficulty, the night reliably stays on solar. paul is one renewable and i just saw. so that's part of a clean, a green, a future here in africa. we're all familiar with wind energy and i drew paula to what did you know the ocean's can also, so also saw so far, oceans cover more than 70 percent of a planet. so we're talking about an almost bound list results here. but technology is not fully developed yet, and there are still some questions. but let's take a look at how it could work. that is

a way to turn the oceans and then on limits at post. all you need to something like this. plus really warm and cold water. let's see me, leave me a wreck to us. technology is called ocean demo energy conversion. so oh tech. and so i mean, it takes advantage of the temperature difference between gold and cold water. when you look at the surface of the ocean, the water here can be quite new because it's keeps it up by the sun in tropical waters that can be around 26 degrees celsius. but the deeper you go and everyone who swims and a lake or dives in an ocean experience, is that the kona, the water gets at 1000 meters deep. the temperature reaches roughly 4 degree celsius. and this difference in temperature is what ocean thermal energy conversion utilizes. it's quite simple, you need a heat exchange of the warm surface. what's the heat? so fluid that has a load boating point. usually that's ammonium, that fluid evaporates aging is theme, and that's the runs

a turbine generating electricity similar to a regular steam. and then this thing gets cooled by the deep sea water back into a liquid, and the cycle repeats. well, see what i itself doesn't boy like here with this thing, my hands on now basically the same water which now heats up the fluid inside. and as it can see, it goes up and bear with me a tom on in there. it was spent. this process can run for 24 hours, 7 days a week, unlike other renewables such as wind or soda. and when you have a great to a temperature difference with water surface water like this one here process can run even quicker and create more energy the wow. 5 that is so quick. the groundwork for this technology was late in 1881 by french businesses. zach i've seen done some bought

a student jobs clothes that actually built the 1st book, unsuccessful low tech land in cuba. in 1930 late interested no tech peak. when oil prices exploded during the old crisis. in 1918 us president jimmy caught the signs of law to ensure the production of 10000 megawatts of electricity from tech in the next 2 decades. the problem here is that you need to get that cold, deep sea water up to the surface or on show where the heat exchanges from major limits. in fact, the is that we need a big temperature difference between the surface and the deep sea water. the one surface water is available only around and a tropical equitorial zone. that's crucial because a smaller temperature difference means less power generates it. yes, so the mission is to dress a real problem in getting people to generate leads basically how well this is dan greg. his company's looking to build the biggest

outtake platform, to date, a $1.00 megawatt unit and sell to me and print to pay what we have. we take it because we've been pulling this really close to kind of thing. well, 523 school and south the white top. we also have the highest lease from grace and the credit ratings. and many of these islands, navy equates uh, rely on diesel generates of power tech put, change that oldest studies estimate that if you disregards practical and financial huddled outset could pile the entire wells. hypothetically it today estimates for a $100.00 megabyte. tech pond can range from $718000000.00 to $1500000000.00 us dollars. a big unknown is called quite today hot plastic pipes,

2 to 3 meters in diameter, a pretty standard before a 100 megawatt pontoons pipes almost 4 times that size. and pipes that big haven't been developed yet. it has proven so tricky that a floating opec near the indian state of tommy and nato did not succeed because of cold water pipe failure. and even if it works, storms can destroy the entire thing. that's what happened to one of the 1st part of plants in 1930. this uncertainty has even driven away companies with more than 40000000000 u. s. dollars in revenue, lockheed martin was set to develop the biggest tech consul dates in china. but drop the project because of the costs. another big question mark is the actual effect on the environment. because you're moving insane amounts of water. we're talking about 4300000000 kilograms of warm water and 2200000000 kilograms of cold water per day for small plants. that's about 16000000 best tops on what's out. there are

a lot of question marks about attacked the economics, the environmental side effects, the cold water pipe, and today's ponds. i'll just wait to tiny to figure anything of that out. and in the last 10 years, not much. this happened. so until series money is put into it will take probably won't be taking off any time soon with inflation driving up for prices across africa and around the world mania struggling to put food on the table . fresh fruits and vegetables come be especially expensive. so how about growing your own and government project into on this vague, it shows that it was how to produce how the food that's how i'm able to turn the thing to operate as the facilities benefits of the community nestled up to the highways offices of downtown johannes, but lies lawrenceville, but it's no high income neighborhood. in south africa, food prices are used by 14 percent this year. and residents here,

a barely scraping by every day and tides, sometimes 8 or 10 as you can see, the green people. i see last time i usually buy the books big favor on last week i go to the, i see the books, it was 75, run the waiting up to fulton shortly. go up. there's a little short little app. so hes managing nowadays. if to cut one way out of the predicament could be urban agriculture. the victoria yards present in lawrenceville is just one example of what could be possible in john is, but this revamped industrial sites much the piece of market bonnie wants to motivate urban dwellers to grow and process their own food. just beautiful, this is mean. it's very good. you can even put it on tv. so you want to be in new i t. i love to so much. here, john, his book self proclaimed dream leading. it's the green business college. a police

dedicated to inspiring people to get their hands dirty in the soil, and we can live in from it. the good economies, big. so as a college, much as a cover, all those sectors that, that i mentioned was touch with a new food. and then the new foods we started, the beginning, and the beginning is foods for about $75.00 euros. the college offers a 5 day workshop teaching skills to grow organic food, cool kids, and preserve it today. my company's teaching has students to be paid, sharpening on how to pick a which device will storage. it's done with household staples like vinegar, sugar also. but the green business college also goes beyond planting cooking on preserves. and we cut part of this training with business skills and exposure, because we're a business coordinator. and do also want them to be and type in us who doesn't go beyond doing this type things for themselves. i attended class that's towards me

that you can also have make a garden on the head stuff. these you cannot see, i don't have space. they've got these also tires. actually, that's what i learned, that we can actually convey to allow waste into something for dad to south africa can produce enough the physics population putting 2021 in full. how soon? so when hungry, because of the rising costs. making healthy food. affordable was one reason can offend poco, got into agriculture, was that since he graduated from the green business college 4 years ago now runs a small urban farm in the north of johannes. but yeah, the trained musician believes that people in cities like i need to really learn how to grow their own food on his plots. he regularly teaches young glucose, basic farming principles. i hope to see everyone not complaining about, hadn't died anymore. you know, customer take this to big get guidance and so that everyone has a smaller, as,

as more than a piece of what we have, you know, and, and then is this pepsi opportunities, that costs, you know, 100 codes of stomach outside does a lot of oil put you into teasing of this so much money. you can pull good offers these cookies for free. did somebody today? another local woman has come to show how to make self watering planted out of old plastic boxes to grow vegetables and herbs at home. valuable, green skills and hard times. okay. all right. so with this group, i say that's an id and that would be heavy. and for this, do i after training more than 2000 students, it's success stories such as venus that inspire months, a piece of my company to spread her green message. what is everything that's right, that's everybody has to corporate or no corporate limits. in order to images,

papa tunnel cover 2 people have to it and everyone. it's going to the president, each new guardian, something and every garden mean listen much more than just help people to meet the needs. at the same time that we gain from in skills, boost vital insect and prompt biodiversity, an air quality in urban areas. while spreading the seats of local empowerment to so when waiting for roll, what a tip for just the same point they should, they can make thanks for joining us today. to check out it. go off or go online to find many movies for each of those stories. it's time to say good bye. i have chris a lens and legal slides area. do join us again next week by the

situation to as a temp, the legacy of dictatorship never entering a new year history but also for the world representatives were elected to compose the draft. this relationship between the economy and the date would be changed. the 1st time that indigenous peoples were put on a level with everyone else is today in society reading, change the 75 minutes on d w. the

systems can be used across different jo, this is the real challenge. it's off whose needs to be incredibly scarce. waste, what the heck us booming business is real new deal and lots, just green washing. what's no cost for almost a bunch of zeros on. it's wanted to say a weapons and he knows how to use this to me and pretend this guy knows about energy in a way that these as much functions have no idea. it's been pretty clear, especially of late. the energy often tend to be the printer symbol. that's what

menu deals for warnings to fix that. but just a glimpse behind the facade of this energy time tell us, gosh, from russia's political weapon starts february, 3rd on d. w. a fateful encounter in the late 19 seventy's former concentration comes in my general, most meisner meant the man who had to maintain him go stump bog known as the beast of sophie bore. shame on you. tell the truth. 2 years later, vaux was dead. and investigation concluded that it was suicide, but the fire give rise to don't really have to go see starts january 27th on the
