ah, listen carefully. don't know how these things you miss today. ah feel the magic discovery of the world around you. subscribe to the w documentary on youtube. ah. rising temperatures and heat whips, 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 come to put 2 more on that in

these additional equal africa, your weekly environment magazine. my name is sandra t. nobody. hi sandra. nice to see you and hello to all a few viewers out there. i am chris ill mps at suntrust 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 a quick look at what's in store on the program, how insects could help mitigate bonnie tricia in madagascar. and why many fishing nets in tamisha 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 ha. 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 hayes me from trash. the children will learn how to design and build their own models. city out of waste. actual i'm on across 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 senari local mom. he started to develop ideas

there, to do drawings. 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 he's now gaining a falling online. he gives most of his muddles away, but some he sells this stadium was quickly snapped up. is la 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. are

val wanna clear police, we didn't recycle before that he bought us and dogmas initiates. who taught us how to systematically separate out trash? there's a local sanitation company, but you 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. ah oh, but i love when you walk to the city, you see garbage all over the place and i see people just throw it anywhere. but every community needs to develop a waste disposal strategy, plugged it in his own industry, in the same book area where i send lives, at least some of the trash gets picked up by him and he needs it for his weekly workshop. so he doesn't, i can set up on the i l, e z the market. it's my goal to teach as many kids as possible how to build these

models out of trash and how to separate trash room 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 are since models, and they really interest me that so i signed my son up so he can make them to did his so can i say that he started giving workshops early this year. the children pay attention to him on of his morals, haven't only inspired a love of building the workshops also make them more aware of the environment. even though the only building models are cheese on solar panels. they're learning more about environmental protection and ascending 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 is into reality. yet,

our sin dogma 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 fame. megacities like lagos, nairobi, angio, burge, a groaning under the weight of population growth houses 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? well, went to kenya to explore some potential solutions. 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 timber jane my yaki launched the green make over of a bank in nairobi and head oh, tiana advises companies on how to build in

a way that's better for the environment or t n o has an appointment at a new apartment building and head 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 2000 as compared to build this business. as usual, if your building is doing 20 percent of better on energy, operational energy, 20 percent better in water, 10 percent better, unembodied energy that has gone into the building. what 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 an, a building constructed over 50 years ago. what is the 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 21 unknown who are able to save up to 20000000 shillings in terms of the annual electricity bills that we paid and 2022 as well. he is in 2020 as a baseline as well. ah, by half. yeah, 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 tons. 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. estimated 2000000 homes are needed right now. and since concrete and steel production amid a lot of greenhouse gases, new materials are needed. materials like cross laminated timber castile ammunition it's tim damn, gives an opportunity for the combination buildings in, in kang, the wildest ledge. 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 view c l t as the concrete of the future.

it's relatively lightweight and yet very strong and means buildings can be put up fast. it's amazingly fireproof too. 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 the secretary of the cabin is stories of the cabin and a thinking of the cabin continues. these mix buildings, cobblins, toys, increases downwards of carbon mythic, aside from the environment, increases demo of coupling western. within our building,

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 interest and project. it will be great if more people followed the lead, reducing copland emissions, and use an energy more efficiently, a crucial to protect in life on the planet, both on land and to see. speaking of the sea on next or poor, takes us to the north african coast. you are very right crease. we now had to tunisia where the fishermen are in trouble is what is left for them is getting more and more difficult. according to an ease study, the mediterranean sea house in fish stalks drop by a fog over the last 50 years. the vast majority of the native species unknown threatened by overfeed chic visitors entering the town of darzy. you 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 and 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 remember think i said if, if we discovered that a toxic species of algae is responsible for this phenomenon of the wind is enough. in 2019, there was a very high concentration of the algae species called korea brevard sniffles. on the need of all astir, said consumption. assume in 2020 it stocks the slightly lower. good. that any error i need the new blood is not 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 ports of got this. when you are the father of 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 best here. so edy and neat ultra betsy 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. oh, nice though good. we've collected

a lot of data up key which will use to make proposals on how to reduce unwanted by catch of endangered species. and we're luck up for all of tenicia, given me up law all who took the law thin, easy lead us rebel, see, has developed a good relationship with the fishing community and the port as are these. 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 plans to recommend this type of fishing. little product with long line and in and hope line fishing. laura,

the fish have the choice there, 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 in the she had a woolsey. papa said deborah mcgrew, preserving the ecosystem in the mediterranean will also require more fishermen like las had been chewing her 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 200, we cause the mediterranean to grace. athens is one of the what a cities in europe and extreme temperatures are putting public health at risk. this is one reason why europe's fast chief heat officer is this. they're not long ago. we reported on the very fast heat of he said he and africa today we introduce you to calculate in europe. ah,

in high summer the sun beat 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. it re capitals 1st and the 1st in all of europe. it's her job to prepare the city for climate change. here she's descending into the city's historical underground, 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 ag aline. mighty volley once water to flow here again, soon, engineers have already drawn up plans and they'll said that they are planning to

create 20 specific points where the, where they tap into the water into the green new parks. the idea is to create a green belt running straight through the city. the creation of parts should produce a cooling effect. the chief heat officer is particularly proud of this small part, which was inspired by japanese gardens. that we have to choose plants that both have a lot of leaves and thick canopy that 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 increase have almost always been accompanied by force 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 parks 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 produces even more heat. so it's actually a pretty deadly makes enough. and the heat is an issue for a gas emmanuel 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 leaning buddy valley isn't a bad idea, but that for athens,

it's likely too little too late. now my babble and of jo, 3, a floor yard and them it'd be nice to have a new park in my neighbourhood with a fountain i can cool off in on hot days on the 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 normally is realistic . come up of iffy or the blue nikki might mean accepted the climate crisis in from with and now about we're trying to somehow live with it to the bottom blog. i'll actually written up a 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 a let is tool here in after pick 2. but as we'll see in this week's doing, to be serious editorship, complete a big role in terms of effecting change. after all, even something as simple as an old plastic boatley can hardly any loses.

ha, hulu. it's time to go in these school kids and toe goes capital of low 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 collected and bring it here. as you're there, i'm in the light 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. risk. as the, as it is referred for goes up or socially, this is important to you because children learn that instead of throwing everything in the trash, they can turn some things into other useful object. spoke with respect to things that have a purpose, what theory office of others. but the center does more than make use of plastic bottles and rubber tires. the machine pock echo low chic also has a bio digester. here young people can see how organic waste is turned into combustible bio gas. oh, and how about you? if you are also doing your bit, tell us about it, visit our website, or send us a tweet. hash tag doing your bit. we share your stories. here are 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, farmington is up a lot of resources like water and ariba land. so how can we reduce on meet consumption and still get enough protein? well, sandra, insects are an option that's an increase in 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 by law law farm laboratory at the madagascar biodiversity center rich in protein . the in said some meant to play a key rule in feeding the country men up it's,

i can so got are they? yeah. now we are expanding and improving our products. and we're finding ways where the necessary materials are not so vast. we can further increase our production, so this will be our contribution enemies to fighting 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 factor, we know that people have their preferences on him. for example, the ne, some insects are more popular gonna meet with our role is to ensure that insects are always available and insufficient quantities. ro farmer 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 on processing the insects is simple and environmentally friendly. and the escrow meant 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 on cinema. now system will also launching into agro forestry on and that

way because of his trees because we use organic foot eliza, because we knew very well the model that we cannot use chemical fits lasers presenter, protected primary for it on at 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. knit seizures and delicious. what more do you want that so for today, we hope you enjoy the program and to be sure to join us again next week until then is good bye from may indigo state nigeria take care. it is also good bye for me here in complex, 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, sometime someplace for eco africa. bye bye. ah ah ah, ah ah, ah, with
