higher society, ah, computers that out some are you and governments that go crazy for your data. we explain how these technologies work, how they can go in for but how they can also go terribly, watch it now on you to a rising temperatures and heat waves. i'm making life almost unbearable in most cities. so we do ask, is there a way we can build sustainably and also keep people countable to more on that in these additional eco africa? you weekly environment magazine. my name is sandra teen over you. hi,

sandra. nice to see you and hello to all of you, viewers out there. i am chris, ill mp's. a sandra said our planet is getting hotter and that means we're going to have to make changes to the way we do all sorts of things here. so quick look at what's in store on the program out in sex could help mitigate money tricia in madagascar. and why many fishing nets indonesia are coming up empty will begin in cameroon, where we meet a young man was very concerned about the impact climate change is having on his home town and the welt, so much so that he was motivated to action. i what started us a bit to fun as now become much more than just a hobby. i

before gets into work. these kids how to wash their project supplies, which is a bit out of the ordinary. they're taking part in a workshop run by 17 year old, our sin, don't everything hastily from trash. the children will learn how to design and build their own model city out of waste. actual i'm on, of course, is on my kitchen. we're building a model of the city of to morrow, with trees and renewable energy to combat global warming for multi multi it all started with an early passion for building. our sin was unhappy at a traditional school, so his parents sent him to a technical school instead. long scenary local mom. he started to develop ideas there to do drawings that he built little things out of stuff like cardboard. gradually he got to the level he's at to day and he had a talent. and as a mother,

i wanted to encourage him to develop his his now gaining and falling online. he gives most of his muddles away, but some he sells this stadium was quickly snapped up. isn't a positive morsel. i didn't just buy it for myself. i also bought it so that i could advertise for him, but if someone wants something built and they see this model and ask who built it, i'll tell them it's the design of a talented, young architect, dribble sit, and actually tick opa don't friends enough material where he lives in yolande, the capital of come room. he goes to businesses and homes to collect trash, especially cardboard and plastic. his helps to raise awareness about recycling. i found one a clear path we didn't recycle before. it was awesome. duncan was initiative taught us how to systematically separate out trash. there's a local sanitation company,

but he can only process limited amounts. only about 40 percent of the trash gets collected. the trucks only drive on big paved streets, but most residents live along small roofs. oh, but i love when you walk to the city, you see garbage all over the place. people just throw it anywhere. every community needs us to develop a waste disposal strategy, plug it into his own industry in the sim book area, where our sin lives, at least some of the trash gets picked up by him and he needs it for his weekly workshops. ready he doesn't, i can set up on the, i'll, is it a mac, it, it's my goal to teach as many kids as possible, how to build these models out of trash and how to separate trash route. i'm and the parents learn as well. around 30 families are taking part. an interest is growing.

they just pay small fee for the tools. i've seen arsons models and they really interest me. that's why i find my son up so he can make them to give his so common . i think he started giving workshops early this year. the children pay attention to him on all his morals haven't only inspired a love of building the workshops. also make them more aware of their environment. even though the only building models of cheese on solar panels. they are learning more about environmental protection and acendo move hoops to inspire even more people. i dream of sharing my passion with the whole world and seeing one of my models being built in full scale. even if his dream isn't a reality yet. our send dog moon is tenacious and continues to forge his own heart . his already created his green district if only in model form

from model homes to the real same. megacities like lagos, nairobi, angio, burge, a groaning under the weight of population growth houses. the springing up on almost every available space but smacked a rapid construction and not so good for the environment. how can the building industry become more sustainable? will went to kenya to explore some potential solutions. i kenya's construction industry is booming. and these 3 people want to help make the sector greener. what kena moutain bay promotes a special type of sustainable temper. jane my yaki launched the green make over of a bank in nairobi. and ted, oh, tiana advises companies on how to build in a way that's better for the environment or to, you know, has an appointment at a new apartment building and had straight for the roof with the project manager or

the inner works for an n g o that helps to certify new buildings according to environmental standards. learning the company, the commission, the project has opted for solar panels and respected other criteria for green building to cover as compared to build this business. as usual, if your building is doing 20 percent of better on energy, operational energy, 20 percent better than water, 10 percent better, unembodied energy that has gone into the building. where do i then your building is considered the green building. as of 2021, there were 43 new certified green buildings in kenya. that might not sound like much, but it's twice as many as there were and 2020. so there's a trend here. but what about older buildings? can they also be made green? this branch of the opposite bank and i robi central business district, is in a building constructed over 50 years ago. what is it, jane?

why yaki is the bank sustainability officer? she's had the ground floor revamped to make it as green as possible. all of the banks, more than 80 branches across the country have undergone the same treatment. there are now energy saving, eli delights in all the rooms, water dispensers, instead of plastic bottles and water saving devices for the toilets and thinks the conversion wasn't cheap, but it's led to enormous savings. the equivalent of more than 160000 euros into $10.00 to $1.00 alone, we were able to save up to $20000000.00 shillings in terms of the annual and the trip to bills that we paid and 2022 as well is in 2020 as a baseline, as well, by half year, we've been able to get a savings of 10000000. and there aren't just financial benefits. the bank told us that the green conversion will cut its carbon emissions 420-225-6000 times what's on how green refurbishing of older buildings is vital and opened up their business

. but kenya is also facing a housing shortage. so more new buildings are necessary and estimated 2000000 homes are needed right now. and since concrete and steel production and mid a lot of greenhouse gases, new materials are needed. materials like cross laminated timber, castile ammunition, it's, tim bam. gives an opportunity for the combination buildings in, in kang, while the fledge really this is because construction and building activities contribute to approximately 39 percent of the company missions in the wild cross laminated timber, or c l t is a product made by gluing layers of wood together, panels can be created in a variety of length, width and thicknesses. many architects, you see l t as the concrete of the future. it's relatively light weight and yet very strong and means buildings can be put up fast. it's amazingly fire proof to when exposed to flames for a long time, only the outside chars build x studio

a social enterprise specialized in design and construction has put up a prototype building near nairobi with a cor structure made of c l t. unlike concrete c o t is considered a green building material that even stores carbon dioxide but it's only truly green if the trees that are used are replaced. oh, when you cut down that tree, you cleared space for another 2 to be planted as can be used in another building. and there sequestering of the company stories of the carbon and the thinking of the carbon continues. this mix buildings cobblins toys, increases the amount of carbon with secretary from the environment, increases demos of cohen, western within our buildings. kenya's construction sector grew by 6.6 percent in 2021. so there's lots of potential for many more green buildings

in kenya. those are certainly interesting projects, it would be great if more people followed the lead, reduce carbon emissions, and using energy more efficiently. a crucial to protect in life on the planet, both on land and in the sea. speaking of the sea on next are poor, takes us to the north african coast. you are very right crease. we now head to, to museum where fishermen are in trouble. what is life for them is getting more and more difficult? according to an ease study, the mediterranean sea house in fish stalks dropped by a fought over the last 50 years. the vast majority of the native species are now threatened by overfishing visitors entering the town. aziz will notice a work of art that looks more like wishful thinking than the reality on the ground . precious you fishers in tunisia bring in a decent catch these days. many simply abandoned their boats. and young people are

leaving. when this villain was looking at the current situation, i have to say that there was no future in fishing. i can only tell young people to consider a different line of work. biologists from the national institute of marine sciences and technology and fox are looking for reasons behind the dwindling fish docs. the prime suspect toxic algae on her. i dramatically a say this if we discovered that a toxic species of algy is responsible for this phenomenon of the wind is not in 2019, there was a very high concentration of the algae species called korea brevard sniffles on the need of all astir, said compress fuel in 2020 it stocks this, like he loa good, any error i need to know blood enough, a per se, but this year that increased again in eva, eva if once in a vast ya, the local, especially in the area around the course of galvez when you add, you, father,

the bas wants to make ends meet with fishers, frequently resort to illegal methods, such as catching fish that are actually too young and small to sell like this swordfish at the fish market in fox. you also find cartilage in his fish like raise and sharks, which are in fact endangered and protected species. bashir saw edy and neat ultra belts are trying to reverse the trend. they want fishers to stop catching sharks and other endangered species. there part of the project med bycatch, which was launched 2 years ago and began with extensive data collection only though could we've collected a lot of data key which will use to make proposals on how to reduce unwanted by catch up of endangered species. and we'll lock up for all of tenicia in the upper

lower all the to the law. thin, easy needa for belle see has developed a good relationship with the fishing community in the port as, as ease. he tells them about the research results and provides insights into the concept of close season. this is when the different species lay their eggs and can't be fished. the evaluation of the samples makes it clear that fishing in the mediterranean must become more sustainable. one solution would be using different fishing methods. trawling can be replaced by long lining, which involves long plastic lines with sardine baited. hooks attached at around 6 meter intervals. met by catch plants to recommend this type of fishing. lin, filled up with long line in and hook line fishing canada. the fish have the choice for larry barella and then the fish that go for the bait wouldn't get caught. they

began it in the others don't. it's completely different to trawling animal which basically catches everything a machine and a woozy copper said. deborah mcgraw, preserving the ecosystem in the mediterranean, will also require more fishermen like las had been shoemaker to switch to alternative methods and not only ins are these. but across tunisia and along the coasts of other countries bordering the mediterranean sea. from an easy week course, the mediterranean to grace athens is one of the what to fit is in europe and extreme temperatures of putting public health at risk. this is one reason why europe's foster chief heat officer is this they're not long ago. we reported on the very fast heat of he said he in africa to day, we introduce you ta colleague in europe. in high summer, the sun beats down on athens, temperatures of 40 degrees celsius or more, are becoming commonplace. and that's hard on tourists and locals alike.

aline, mit easily always keeps her water bottle handy. she knows all about summer in the city, in the risks it poses, because she's athens chief heat officer, the greek capitals 1st, and the 1st and all of europe. it's her job to prepare the city for climate change . here she's descending into the cities historical underground, but together with an employee of the athens waterworks, it's home to hadrian aqueduct, an underground tunnel, almost 20 kilometers long built by roman emperor hadrian. in the 2nd century e. d. a lini, murray valley once water to flow here again, soon, engineers have already drawn up plans and they'll say that they are planning to create 20 specific points where the, where they tap into the water into the green new barks. the idea is to

create a green belt running straight through the city. the creation of parts should produce a cooling effect. the cheap heat officer is particularly proud of this small part, which was inspired by japanese gardens. that we have to choose glance that both have a lot of leaves and thick canopies and without a loser there leaves in the winter. but also can, can do not need the enormous amounts of water and can survive in difficult conditions for several years. now. extreme heat waves and grease have almost always been accompanied by forest fires, which are increasingly becoming a threat to the capitol. elaina moody really knows that time is running out. in a few decades, large parts of this city of close to 4000000 people could become uninhabitable. already,

athens is often the hottest city in europe during the summer. and we don't have a lot of barks and, and green spaces. and we have a lot of old people, the fact that the surfaces are, are we have a lot of surfaces that then to heat up. we have a lot of cars that produce even more heat and air conditioning and produces even more c. so it's actually a pretty deadly makes enough, and the heat is an issue for a geese emanuel and not just because he likes to run long distances. he's an actor and one of the most famous climate activists in greece to promote climate protection. the athenian ran 2500 kilometers from here to the world climate conference in glasgow. scotland last year. he thinks having a heat officer like a laney, buddy valley, isn't a bad idea. but that for athens, it's likely too little too late. now my babble an of your 3 a 4 year old allow me to be nice to have a new park in my neighbourhood with

a fountain i can cool off in on hot days, vulnerable to store. but to be honest, it seems like giving a cancer patient and aspirin, alamahood, emily, rush, speeding. i get the impression that we've already surrendered. no misery unless you come up of iffy or the blue nicki my beginning, accepted the climate crisis in from with and now about we're trying to somehow live with it the border blog. i locksmith read level shuttle stories after. after all, this ancient city has survived many a crisis in its almost 4000 year long history. waste management is another big challenge for many countries and let his tool here in after pick 2. but as we'll see, release weeks doing the b service edition can play a big role in terms of effectively change after all, even something as simple as an old plastic bottle can hold any loses bah. hello. it's time to go in

these school kids until goes capital of law may have been looking forward to their outing to mazique park echo logic, a very unique education center. all of the buildings here along with the pavement, were constructed using waste materials, dead doris area, bhaskar. i love this place because things that i thought were useless ones are actually useful. so i think recycling is important and everyone should do more of it. but from now on, when i see trash, i'll collect it and bring it here. as you're there, i'm in the lights in tell go more than $2000000.00 tons of plastic waste and up in the environment each year, according to official figures. even though the country does have waste management centers, the recycling rate remains low. that's why raising awareness of the problem is critical. as it is referred for,

grows up or function that this is important to you because children learn that instead of throwing everything in the trash, i can turn some things into other useful objects. work with respect to things that have a purpose, what 3 all for for the other. but the center does more than make use of plastic bottles and rubber tires the machine park echo logic also has a bio digester. here young people can see how organic waste is turned into combustible bio gas. ah, and how about you? if you are also doing your bit jealous, visit our website or send us a tweet pastor doing your bit. we share your stories. here on equal africa, we frequently address the issue of food security. more and more people around the

world are in desperate need of adequate nutrition, but practices like livestock forming in his of a lot of resources like water and ariba land. so how can we reduce on meet consumption and still get a large protein? well, sandra, insects are an option that's been creating a lot of balls in recent years. let's take a look at what people are cooking up at a farm in madagascar. just consider it's a little taste of things to come. some people find bugs on the plate on appetizing, but these crickets are being bred by the thousands in bella farm laboratory at the madagascar biodiversity center rich in protein. the insects i'm meant to play a key role in feeding the country may not be taken from that day. yeah. now we are expanding and improving our products and we are finding ways where the necessary

materials are not so vast. we can further increase our production. this will be our contribution. i'm is to fight a money tuition in mother garza here. tina needs funds. i covered my gasket more and more forest is being cleared to grow food. madagascar has lost a significant amount of its forest cover in recent decades. some tropical wood is exported, but over half is used for cooking. many farmers also burns sections of the forest to create new fields. then there's climate change, which is also causing problems for farmers. rain, forest soil is known to be poor, but extreme weather and erosion are further degrading the land. this, coupled with increase in drought, is leading to more and more crop failures. this is where the newly founded insect processing facility comes in. here, different edible powders are produced from dried crickets and worms with the aim of

bringing insect putting on to the food market. miss fact that her where know that people have their preferences on pending. for example, the ne cut, some insects are more popular gonna meet when our role is to ensure that insects are always available. and in sufficient quantity so far, he says if under the men's and they, when the manufacturers believe they can produce enough powder for about half a 1000000 meals a year, keeping and processing the insects is simple and environmentally friendly. and the escrow means is also used to produce natural fertilizer for agriculture to isa. we're trying to vary the insect fits license for use with coffee, plants, clothes and cinema. gnome system will also luncheon into our go forestry and on that, where, because of his trees, because we use organic foot eliza, because we knew very well the money that we cannot use chemical fits laces

presented protected primary for is one of the last put on our dried and roosted insects already popular dishes in some african countries. this pop up restaurant in cape town, south africa, for example, only serves insect dishes. considered booth nutritious and delicious. freshly fried crickets or worms, sell like hot cakes here. nits, this is an delicious. what more do you want? that's all for today. we hope you enjoy the program. and to be sure to join us again next week until then is good by for me, it'll go state nigeria, take care. it is also good bye for me here in counselor, but don't forget to check in with us and all our social media platforms, or even a web site that you can find all those shows and reports as well as other interesting content that i'm sure will be helpful for you to see next week,
