leading the way, run like a small business, it is self sufficient and economically successful. for go on d, w, german w was singing with a winning offer is up in worldwide. and for every language level, learning german has never been simpler. german to go ah, a climate change is transforming a wild, causing us to question all will certainly tease and bond and longstanding practices

to adopt. we'll need to do i rethink. welcome to this new edition of africa. i am sandra tree. nobody are joining you from counselor here in uganda. and i am chris alone saying hello from nigeria. sometimes a 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 treason mother did. this is a bio, despite on going drop ship go to france. we are, researchers are turning to invasive plants to make environmentally friendly cosmetics. and go to later connor in kenya, where the l. maloof fishing 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 court yard looks much the same the world over. but this boarding school in north western tunisia is different from most. it operates on a sustainable business model. project initiates a lot for her, marty aims to improve living conditions, education opportunities, and future prospects. not just that 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 here through energy autonomy in their own food, self sufficiency of them. why fostered?

because this country was going through in very deep crises, economic social, on climate crises at that of an impact on childhood climate and therefore on future generations. they don't follow porthos in house or wasn't wiggle 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 here 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 hen month in 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, said 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. an 8 hacked half farm and shows the students get healthy and balanced meals. satler's produces salt to local shops or wholesale markets,

providing the school extra income. but the land bears more fruit than that. on acount, 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. we shy hampshire has been working here for over a year. when last all lowercase the wall away, john project means everything to me. if you have it on a contract, i used to be unemployed on multiple days. but it's changed my life completely. complet morbidly, to cope with the increasingly sparse rainfall. drought tolerant vegetables have been planted and trick irrigation and stalled monasticism. this allows us to water just along the line. the seas have been sown was all over that way. only the amount

needed is used and no water is wasted as we, as it also keeps weeds from growing the flashing anymore. is it 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 lorenz and hitches are lovely afternoon, my siblings and i have been coming here 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 fact i love there are other club that i chose basketball because i love 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 school. he's got the results have been very positive, so far, illusion and that's all down to efficiency of it by making use of what's available by exploiting the power of the sun on it. that's very important. so prism portal is for hawker says should more disease and hopefully this model can be adapted and applied in other places requiring i booked those on the wall look tree hummadi 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 the we can maxim is let's invest in children to build a better future 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. scientists are the university of mon paulia have discovered the surprising feature of the invader. as you this combine this weeks, doing your bits. 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 montpellier university are clearing the not we'd be discovered. it has surprising properties. crushed dried and ground into powder. it can dramatically speed up chemical processes.

for the 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, it put on the vegetable powder is already itself an acre catalyst. that is to say, a reaction booster, which will allow us to transform a simple molecule into a more complex molecule clicks the researchers save is so called eco catalyst. could make the manufacturer of products like face creams more environmentally friendly and wendy, cuz the field of cosmetics today, still use of 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 your start up at the university of more video. and how about you?

if you are also doing your bit, tell us about his visit our website. oh, send us a tweet. hash tag doing jo, base. we shack 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 digest at his construction sites here in africa already use as much summat, ice 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 280000000 tons of concrete waste every year. but at least this rebel will soon be repurposed into new concrete. accompany in southern germany specializes in recycling, building materials, a crushing machine turns the concrete pieces into small granules, which are sorted by size. the granules are then sold to cement manufacturers. china onside processing can save millions of truck kilometers. how many kilometers inch bon sandy used to produce concrete is usually doug from large pits, 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 pet. it's cleaned uncivil before being sorted by size. this obviously bama. everything here used to be a bridge or a floor slab or a house, and we're making something new from it called let him up. all this material would have ended up in landfills and in some dump room. and now we can use it to make high quality building products that are used in new construction project. will i use the recycled product? 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 account 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 with this name. so 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 me the way the clues will be for your other solutions are also being developed at this cement plant, for example, permeable, concrete that can absorb rain, water helping improve been climates as cuz some of the vague mazel, this interstate rainwater seems through this concrete and goes under ground one which can help improve ground water level synchron fossil household, beautiful bay. so 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. improve omagh if, if you were primarily talking about up cycling horn quantity, we want to produce a very high quality design which be 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 on limbo 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 another global new global scale l. what i want to show if fume about key see key high here to d key. see key high means leaving trees, tampa. we will start with announcements in the village, and later in the evening we will show the fuel on it. not lost in america. it's

still early afternoon and the villages lighting their 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. they are digging here because of another movie presented belinda lindell and the lead foundation in partnership with the dutch n g o coles. just dick it, john mooney. it remembers it. well is he digs in trench and fuels it with grass seed? little from the help lumber mom again 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 bases, which we filled with seeds to help the fields recover. and that was all about in the color. while melinda wasn't ever, it's 5 pm and leaned am, lean was colleague, makes an announcement that the film screaming of taking place that evening. it's

a welcome change for the villagers. they 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 because the land became baron and that harvests got worse law. now we want to show people how to the claim that moisture so that the yields increase in they have enough posture to feed their families shell. hm. and it's finally short time. 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 am declaring war. let's do it together. i don't want to see any

more trees chopped down. i'm going you want it to rain every one in ingle rocha. 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 should 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 zenia, 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 such best since intern zeniah and kenya, people here in one euro, 50 peson, diligent workers like dina garcia, can manage 580 legacy in among 4 ones. yes, the same with a 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 liver. my then whom was i was able to let ruin my then 11 go. if we employ these practices, they helped us to take care of our life stock. and you know, 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 bases, 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 held to slow down global warming. and the people of anger luca, a doing their part was staying cane, east africa. we know, look for answers to the pressing question. how can people insure food security in the face of climate crisis? these issue is particularly argent for people who leave on the shores of lake to are continental than canyon. the elmore people have long relied on fishing, but that is becoming increasingly difficult. the entire community is under threat. we paid them on visit. alexander lin appear,

looks out over the lake. that's been the source of life for his pupil for centuries . the old more nor are an ethnic group that leave in the north of kenya's eastern province. born in 1958, lin appear has watched his car to slowly disappear over the ears due to migration into marriage and more recently climate change. and now the and more low i losing their land and suck with sites to rising water levels in lake to canna have engulfed to roughly 800 square kilometers of land over the course of a decade and letting the lake by 10 percent. bob ogo, renew my venerable bugger. them in the past. there wasn't any water hand. it didn't reach this far. i didn't. now the water has completely flooded our village. oh, there used to be roads here at the yacht. now there is only water everywhere, you look most of arming, a goddess which i swallowed up my new. ringback wave totally disappeared by me. i'm another my were the other big as rainfall became heavier and more

frequent, the lake expanded and changed the landscape so much that lyn 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 so much. so was the fresh water pumping station. now they get their water from the lake which leaves them susceptible to diseases like most here, lynn appears 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 far, the strain on local families and the children's lives are affected in other ways too. there are 2 schools at elmore la bay,

but the primary school is now partially so much brazilian county. you a quote in the past we could walk to school who had led lenses. it did, but when the flooding turned our land into an island that was no longer possible theatre took, i did then the county government, ellen provided boats for us to get there. the to, to were gay. disable an awkward, rudy. up on your way and often overlooked side effect of global warming is a school disruption. it threatens both the physical safety and cycle social well being of students and teachers. richard smarter'n is observing a drop in academic performance as well as attendance. the once crowded classrooms are often half empty. smarter'n who's been teaching for 20 years, said he's never witnessed anything like this. claimant, fin you back in average, gives them the climate change just threatening the existence of the molo tribe.

because we fully depend on the lake from fluids over my so they usually don't have fish. we suffer in, we're work, we don't have fish to sell and buy balanced. music was on. we're one of them. i get with those apples. when i be a woman, that only is a part of the valley to submerge. but so at the water, my blue didn't cover with joy existence, fresh drinking water yesterday. really? uh huh. saw the remedy to glamour idea. glinda fresh water for the animals are still fighting to uphold their traditional customs and culture. while up to a 1000 people identify themselves as and molo most awful families that have intermarried with other tribes in the region. like this o'connor, some blue and red dealer that to has diluted their unique identity. but they want to preserve what they have and a 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 renews the level of water that is going to like to corner us where us it would reduce their lotion. betty subtle, gorsling 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 communities totally 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 our brings us to the end of our show. i'm chris alarms,

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, on our social media channels, or even better write to us if you have any good ideas on how to protect the environment. so long for now. take care. a with
