any invisible river that flows through the sky starts march 23rd on d w. sometimes a seed is all you need to allow big ideas to grow. we're bringing environmental conservation to life with learning pass like global ideas. we will show you how climate change and environmental conservation is taking shape around the world and how we can all make a difference. knowledge grows through sharing. download it now for, for ah, with climate change is transforming a walt causing us to question old. so tony tease and

a bond and longstanding practices to adopt, we'll need to do a rethink. welcome to this new edition of equal africa. i am sandra tree, no video joining you from counselor here in uganda. and i am chris alone saying hello from nigeria. sometimes i rethink can also mean revive in old traditions. as one of our reports shows on here is what else is coming up today? we had to tanzania to see how please amanda j. this is a vibe, despite on going drop ship, go to france, we are, researchers are turning to invasive plants to make and very mentally friendly cosmetics. and go to later connor in kenya, where the algola efficient people are fighting to preserve their way of life. our 1st report at texas certainly is here where conditions in schools are often shooting. in some cases they are no longer a safe environment for the students. mismanagement and economic was had taken

a heavy toll on public boarding schools, attended by some of the countries poorest children. now, these are often the worst affected. this is why attorneys in n g all is aiming to build a brighter future for kids by turning schools into social enterprises. the sight of students congregating in a courtyard looks much the same. the world over this boarding school in north western tunisia is different from most. it operates on a sustainable business model. project initiates a lot v. her marty aims to improve living conditions, education opportunities and future prospects. not just but unity as most impoverished children, but their families to report. oh, well i really want to we can project is quite simple as it sounds like it seeks to transform public schools into social enterprises. go through energy autonomy in

their own food, self sufficiency of them. why bhaskar? because this country was going through very deep crises, economic social, on climate crises at that of an impact on childhood agreement and therefore on future generations. they don't follow porthos in our store wasn't real. when hummadi 1st visited the school in 2012, it was in a catastrophic state. the facilities were dilapidated. the electrical systems hazardous. there was no insulation or heating, although temperatures have regularly dropped below freezing in the winter. the institution was so short of money ordering students could only have one shower among pupils for falling sick. such conditions are unfortunately common and chin as he has schools, especially in poorer rural areas. the countries once renowned education system is a lang over $100000.00 pupils, dropouts each year. but now applications at their school in the town of mac. tar

are up and absenteeism down and mainly been m. r, attended the school until last year. we believe that the school helped us realize we can dream because before we didn't dream, now we do when we are confident that we will achieve our dreams. this will help will and headman then the schools transformation is initiated by taking advantage of a plentiful resource. the sun comedies and g, i raised money to install solar water heaters, so the boarders could take regular hot showers for the 1st time. over a 100 solar panels now produce 4 times more electricity than the school uses. the excess has enabled the project to settle outstanding power bills and supply electricity to 3 more schools. insulating the dormitories also lower energy consumption and cost. food autonomy is another important pillar in the self sustaining model. and 8 hacked her farm and shows the students get healthy and

balanced meals. satler's producers sell to local shops or wholesale markets, providing the school extra income. but the land bears more fruit than that. on our current, we offered agricultural training to parents who are out of work american and now they've become entrepreneurs because we also set up an agricultural business and made them shareholders the farm employees, 8 parents who now receive fair pay and other benefits like social security, with shy of shy of has been working here for over a year. we must all lowercase the wall away. john project means everything to me. if you have it under control, i used to be unemployed for much conversion but has changed my life completely. complet morbidly, to cope with the increasingly sparse rainfall. drought tolerant vegetables have been planted and trick irrigation and stalled manners use. most of them kiss allows

us to water just along the line. the seeds have been sown was all out that way. only the amount needed is used and no water is wasted as we, as but also keeps weeds from growing glass in any movies at a butter funds generated, we're used to refurbish buildings and out features like sports facilities. basketball is one of over a dozen extracurricular activities on offer. this group is mixed gender. say that and yeah, i mean, i've been here for 2 years, and this is where all my friends and hitches are lafayette flin, my siblings. and i have been coming in to the club since i was little was if i was so happy when i heard there was going to be a basketball club there. and there are other club that i chose basketball because i love each other about ah, another popular courses, music, robotics web design and entrepreneurship or so on offer. and there's a reproductive health program. numerous civil society initiatives working to

improve chin as your schools. but the waller, we can project as seen as unique by many, for it's long term vision with sustainability at at school. he's got the results have been very positive so far, illusion and that's all down to efficiency. i think by making use of what's available by exploiting the power of the sun or as well that's very important. so suppose appleton is bianca says should moody's and hopefully this model can be adapted and applied in other places requiring i thought those all the while look she her marty, has his sight, sat on exactly that, he plans to replicate the model developed her in 3 other regions and ultimately throughout gina's here, after all the while we can maxim is let's invest in children to build a better feature. over. we've often reported on eco africa above the damage done by invasive plants, such as water high seas. in france,

japanese not wheat is also in famous for displacing native plants. species scientist at the university of mon paulia have discovered the surprise and feature of the invader as you discover in this week's doing your bit. bah! every country helps with japanese. not weed has spread all along the, a little river in southern france. be invasive. species has displaced many native plants here. and it's shallow roots are putting the river banks at risk of erosion . researchers at mumford, yay university. are clearing a not we'd be discovered. it has surprising properties, crushed dried and ground into powder. it can dramatically speed up chemical

processes. whether i assume it's either the roots or the leaves which are rich and minerals, metallic minerals of interest to them, they'll be thermally treated to obtain this vegetable powder, put on the vegetable powder is already itself an eco catalyst. that is to say, a reaction booster, which will allow us to transform a simple molecule into a more complex molecule. plex the researchers save is so called eco generalist, could make the manufacturer of products like face creams more environmentally friendly and wendy, cuz the field of cosmetics today still uses mineral, or petrochemical catalysts. now, this idea of plant base catalyst has never been developed before. jemma to develop the of the researchers have already developed at least 60 plant based catalysts. they're now being marketed by a startup at the university of more video. and how

about you? if you are also doing your bit, tell us about is visit our website. oh, send us the tweet. hash tag doing jo, base. we share your stories whoa, new product from nature. we also need new products for nature. in other words, we need to rethink our production methods to ensure we don't cause even more environmental devastation. for example, the construction industry is responsible for almost 40 percent of c o 2 emissions worldwide. that is right grease and concrete, which is made with summit, is the climate killer largely responsible for diet. a statistic. construction sites here in africa already use as much summat as in europe and not upward trend look said to continue. so it is high time to start recycling this building material. a

few farms in germany, a doing just that. germany creates 218000000 tons of concrete waste every year. but at least this rebel will soon be repurposed into new concrete. accompany and southern germany specializes in recycling, building materials. a crushing machine turns the concrete pieces into small granules, which is sorted by size. the granules are then sold to cement manufacturers, which either onside processing can save millions of truck kilometers, how the kilometer inch bomb. sand used to produce concrete is usually dug from large pants, then transported hundreds of kilometers. the same is true for gravel. the 2nd component in concrete,

but sand and gravel are becoming scarce. as this construction recycling plant, old red roofing tiles are also used to produce concrete, recycled sand is taken from an old construction pit. it's cleaned uncivil before being sorted by size of the of a bomb. everything here used to be a bridge or a floor slab or a house and we're making something new from it. hold them up. all this material would have ended up in landfills on, in some dumb and i now we can use it to make high quality building products that are used in new construction projects. will i use the recycled products? so then delivered to customers like to this nearby concrete manufacturer. this company is different than most of its competitors, because globally, only 2 percent of building materials get recycled. but this company depends on recycled materials, which accounts for 30 percent of its entire production and the recycled concrete is

less expensive to the materials a mixed in this plant and then delivered to customers. the final product will look like this. a building material that many customers prefer over conventional products. this new tool, while it's becoming more popular because people understand that we have to conserve resources. and that's why demand is now greater than before, middle away liquids will be for your other solutions are also being developed at this cement plant, for example, permeable, concrete that can absorb rainwater, helping improve urban climates. this could somebody, they mazel this interstate, rainwater seeps through this concrete and goes under ground one which can help improve ground water levels include fossil household, rita, for basal ah, this could help prevent concrete deserts, with completely sealed surfaces and recycled. construction materials are also

brought to this southern german company. they are constantly testing new stone formulas in the lab, experimenting with different colors, shapes, and components to increase the portion of recycled content, which is 30 to 40 percent. the recycled look is intentional and performed. give a film. we're primarily talking about up cycling, the horn quantity. we want to produce a very high quality design. b, this tile pattern creates an entirely new surfaces. you look on the, on the gun loyal booklet. this is what it should look like, a new generation of recycled site, walk with lots of green grass sprouting up in between and space for water to seep into the ground. this is what many customers now, once a new growth market for the concrete industry, many regions of africa also have ground surfaces which don't lead water through

before completely different reason. it is because the rain seasons fail, living much of the grown dry and hardest concrete. so when it does rain, the water can be absorbed and simply one so. so what conform is due? next report takes us to the russia region in pennsylvania, where an initiative is putting a simple but is victim idea into practice. here in ingle, luca village, not than tanzania, hardly any one has the tv. that's why i leaned am limbaugh brings a small more bell cinema with her. she was here a few months ago on behalf of the lead foundation. it tanzanian conservation organization. i am on doesn't love a robot and the global scale. what i want to show a film about key see key hi here to d q. c key hi means leaving trees, tampa. we will start with the long lines in the village,

and later in the evening we will show the fuel on it not lost in america. it's still early afternoon in the villages lighting the a fuel digging in the born dry it holes in the f as far as the i can see, it seems like all 7000 residents are out and about be are digging here because of another movie presented by linda lingle and the lead foundation in partnership with the dutch n g o coles. just dick it. john mooney, remembers it. well is he digs it, trench and fuels it with grass seed little for little grandma, while my going get on the film told me that you can do something about the dryness and drought of recent years for like a day or glove. we can tell the land and create water basins, which we fill with seeds to help the fields recover, and that will come by the look on the coil. melinda mars's and it's 5 pm, and linda m liam was colleague, makes an announcement about the film screaming of taking place that evening. it's

a welcome change for the villagers. the only get to see a film every few months. the children excited to see what's coming. yes, an emma, this feler explains how to protect your land from drought. people have cut down the trees many times in recent years with god the land became baron and that harvests got worse. now we want to show people how to the claim that moisture so that the yields increase in they have enough posture to feed the family on my shell. hm. and it's finally showtime. it starts with j. manya is very popular. comedian interns idea. well let me catch you cutting down any more trees or fry. you like an egg in my hand. i'm declaring war. let's do it together. i don't want to see any

more trees chopped down. i'm can you want to rain? every one in ingle luca, once rain in the film is well received. people here have become familiar with drought over the past few years. what it means to be thirsty all day long. the feel showed the village of the small shrubs or trees toms can grow into large trees. if given a chance. first viable plans are selected. next, the approved so that the only strong as should remain. then the trees must be marked for every one to see any fortunately, the plant must be protected from hungry kettle. according to the campaign, this method is managed to save over $9000000.00 trees. intern zeniah, a re greening measure of this magnitude has an impact on the local weather and can also bring rain. this means the country will pull down and crop yields will improve

. at least in theory, in anger, it's still a dream door. the last month it seemed less precipitation than in previous years, which is one reason why the digging rein. bessemer, according to the campaign, they are now over $200000.00 such bisons intern, sonya and kenya. people here in one euro, 50 peson, diligent workers like dina garcia, can manage fife, eddie mckenzie in among for ones. yes, the same with her. we make money and digging. now. later when the grass has grown, it will benefit both our kettle in us because we save our cells, the trouble of carrying food to the kettle. never mind anyone was i was able to let ruin my then 11 go. if we employ these practices, they help us to take care of our life stock. now to say, dear man, in full rainwater normally evaporates on the dry soil,

but now it can collect in the basins. this gives the water more time to see if into the soil, and this allows vegetation to grow, not only inside the basins, but also around them. this re grinning program is in full swing and gaining in popularity. strategies like this one have an impact on the global climate and could even help to slow down global warming. and the people of anger luca, a doing their part was thing came east africa. we know, look for answers to the pressing question. how can people issue food security in the things of climate crisis? this issue is particularly argent for people who live on the shores of lake to kind of northern canyon. the elmore people have long relied on fishing, but that is becoming increasingly difficult. the entire community is on the threat . we paid them of visit alexander lin appear,

looks out over the lake. that's been the source of life, of the people for century, the more know or an ethnic group that leave in the north of kenya's eastern province. born in 1958, appear has watched his carter slowly disappear over the eas, due to migration into marriage. and more recently climate change. and now the mall are losing their land and suckling sites to resume water levels in lake to kind of have in golf to roughly 800 square kilometers of land over the course of a decade and letting the lake like 10 percent. bob ogo mcdaniel burger. then in the past there wasn't any water here. it didn't reach this far. i didn't. now the water had completely flooded our village who they used to be. roads here. now there is only water everywhere. you look. most of i just swallowed up my. ringback they've totally disappeared, my knee, my neck, my why?

dog, the egg, as rainfall became heavier and more frequent, the lake expanded and changed the landscape so much that lynn appears. village was suddenly situated on an island. many moved as a result the others had to make major adjustments. not only was the path to the mainland, now some must. so was the fresh water pumping station. now they get to the water from the lake, which leaves them susceptible to the season. the like most here, lynn appeared, has been a fisherman all his life. but ironically, the expanding lake has actually devastated his livelihood. before the waters rose, he would catch about a 100 fish a day. now he averages less than 10. fish can be found in deeper waters, but the boats are in safe enough to take out that far less fish means less income and less to eat. putting a further strain on local families the children's lives are affected in other ways too. there are 2 schools at and malo bait,

but the primary school is now partially submerged. gazillion id, you a quote. in the past, we could walk to school who had leg causes it did, but when the flooding turned our land into an island that was no longer possible theater took, i did then the county government jaelyn provided boats for us to get there. the 22 . okay. disable and elk literally a banging vine, and often overlooked side effect of global warming is a school disruption. it threatens both the physical safety and psycho social well being of students and teachers. richard smarter'n is observing a drop in academic performance as well as attendance. the ones crowded classrooms are often half empty. smarter'n who's been teaching for 20 years, says he's never witnessed anything like this claimant thing. that even average the exist than the climate change,

just threatening the existence of the molo tribe. because we fully depend on the lake from fluid overwhelming. so they usually don't have fish. we suffer. we're one, but we don't have fish to sell and buy balanced music was on was on my get with those apples. when a beer warmer than not only is part of the village submerged, but so at the water, my bluetooth didn't come up with my joy existed fresh drinking water yet to be really. uh huh. so the remedy the glam radio glenda, fresh water for the elmore low, are still fighting to uphold their traditional customs and culture. well, up to a 1000 people identify themselves as and morello most awful families that have intermarried with other tribes in the region. like this o'connor some bull route and reveal it, that too has diluted their unique identity. but they want to preserve what they have and looking for ways to make the situation more tenable. francis medea

is a climate scientist based in the lake to kind of base him. he says, putting in trees would be one relatively simple, yet effective step in the right direction. it will reduce the level of water that is going to like to garner. i swear us into the newspaper, lotion, and that is also hoarsely to another level. planting trees could help, but it would also mean giving up arable land, and most importantly it wouldn't help immediately. the fate of this small community, starkly, illustrates the severity of the climate crisis. the elmore low have lived in this area for 2000 years. if nothing changes, it could all be lost in, within just one decade. if we don't manage to mitigate the effect of climate change would might so all but facing the same challenges as the old model. people that's food for thought for me and for all of us. and that brings us to the

end of our show. i'm crystal omes, simon, though, from ogen states nigeria. and it is a good buy for me to sandra to nobody here in uganda. and of course, don't forget you can always stay in touch with us on all our social media channels, or even better, right, to us if you have any good ideas on how to protect the environment. so long for now, take care. ah, with ah, with
