participants here to date it broken by renewed a pledge for a weld in peace and freedom. that was thomas barrow in balkan by den you're up to date here on d. w. and use of cost is much more now website t, w dot com and on instagram and twitter and youtube at dw. so i'm tired, rating and building have a great day. oh, what people have to say matters to us. mm. that's why we listen to their stories. reporter every weekend on d. w. sometimes a seed is all you need to allow the 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, feel free. ah, most people and nature are experiencing extreme temperatures and tramps in our cities each year threatens to bring record hate jump to. we've measured 70 to 80 degrees celsius on glass and steel. the behind here it might be 30 or 30 by, i thought, dense development concrete in ashville to become dangerous rent the 4th of it's

nearly impossible to cool them down. in the understood, it's a city of facades which reflect and tend to make the problem worse. for libya, gore's off high temperatures threatened now health. we need to cool down. i fair to say if you have a gravel roof, make agreed for as long as global warming has been a reality. so has the strain of heat on our cities. but now gardeners and architects are coming up with some cool new solutions. motion builds is 27 meters above ground, working on europe's greenest tire ice. barracks is a passionate god, not with this green facade. he's providing a natural air conditioner in the heart of the city. if run some fun, yes, anita,

leaves are starting to retract and slowly dry out and on. but thanks to our watering system, a vessel there are also a rush usa clever becomes ah, this shopping center is called clue bogan to named after diesel dos, coon, exactly shopping area. the $30000.00 horn bin plants said to call to building to happen noise and absorb carbon dioxide in there, fixed some of the plants are already feeling the heat. they're part of an effort to counteract increasing heat waves and german cities. a consequence of climate change . the whole means of only be for 6 months. so this still knew this supplied by a special irrigation system. nearly $35.00 degrees has it running with 5 leaders a day for the tubs and 15 leaders per square meter, city, michigan,

must not outside. what's that red outage most diagnosed with? it's a malfunction in the asset supply. we'll have to go to the basement and vent it with the system uses a lot of water, fonts, 1000 cubic meters here, but it has enormous benefits to city residents. uses worth of, of that water gets turned into cooling element. you noticed that when you walk around out there at one and if us near the facade, there are significantly cooler temperatures as well as humidity isn't so taken together. it's 5000 cubic meters of water that the people of dusseldorf get back through the system book on thursdays unlike of. and unlike air conditioning, the plants don't blow out hot hand to the city. kate increases have been traumatic from 1961 to 1990. the average for july was 16.9 degrees celsius. in the city is after that, it was $18.00,

an increase of $1.00 degrees. vamped in pa, twin of glass in high summer. we've measured about 70 to 80 degrees celsius on glass steel shuttle behind. here it might be 30 or 35 degrees in that i've been involved. if you look at the leaves school, they're structured in such a way that they can't get hotter than 35 or 36 degrees criminalized because the cells would burst them and the moisture would cool things down again. but that's also why they have a cooling, a fax of us. it's just how nature works. so i feel fortunate that one night you too can experience suffering. and martin pelts and his team still have what to do with the home, the implants, a few kilometers away at to source river port, the landscape gardener is working on another project. he meets with architect christoph in hovan. he designed to pub over 2 people with him on 4th. let him know about this. we don't jump right into it in the fall, but we take

a look together and decide whether we could do it before the new leaves come in the spring. just i'd like to look at it with you on site with it i might inflicted some helps to pay. i have completed many projects together in an oven, and his architectural studio have focused on sustainable building since the 19 ninety's winning many awards. now he wants to shake up urban planning on house boundaries when you build a house like this one, for example, when you're using up a piece of land, a piece of the earth, if you will. and you can think about the green mass that would be on the side as untouched forest. if you were to just leave it to its own devices for 50 years, the nation forces management. and so if we evaluate the ecological and social value of the nature that would otherwise be there, then we have to do something that compensates for us to discuss what's as long as it's like the roof with the home be implants that it's not just city centers germany's industrial zones need to become created to research is in once to land

are about to take to the sky. what's the humidity you push to 90 percent, 30 or 90 percent. and evie schneider is doing a final where the check is going to be hot and humid day perfect for her project. the measurement engineer is going to fly over some specific industrial areas from the air. she'll use a thermal imaging camera, she get precise dosher from industrial facilities, should be able to see the temperature values of individual companies, streets, and squares. these days, many industrial zones don't ever properly cool down in summer. the project is run by a non profit. the bonds, so had shown with funding from germany's ministry for education and research. the

goal is to reduce heat from industrial areas, making the more sustainable. unless it's as though alcohol cool, you can see that there is no cooling left. but frightening was if you can tell what it built up areas like, and whether there are differences, whether fresh air can pass through, whether trees or a river have an effect. and how permeable surfaces are you can see a difference between tara and paved, or if it's paved with granite, because that heats up quite differently. the differences are there to see. to see this. the thermal image is a precise with cooling areas, blue and hotter pots red down on the ground. uncle valentine is in the bowl halt, industrial zone. the thermal images help us. you convince local authorities and companies to make changes. because industrial areas are quite literally hot spots either. there anyone who knows industrial areas knows that they have many parking

lots and a lot of wide roads for the trucks and lots of stationary vehicles. yeah. there's a lot of space that simply covered with asphalt, which also means there's a lot of potential to change things with rising temperatures, the heat in these areas increasingly affects the people who work here to in germany, around 56 hectares of nature and countryside lost every day that's the size of 76 football fields. the government had aim to reduce this figure to 30 heck to his by 2020, but that's now been postponed to 2030 this wild plant bed was only planted in the spring on co valentine is here to make business owner cottage, folic, and gonna t o grungy in law, never get to see if the plants of already made a difference. provo at off, my hus. let's see what the airplane brought us have the read or it is the hotter it

is. is the highest. and we're here. oh, here's the bed. oh yes, nice and blue. oh, oh money i understand. i'll come. you might think it's the effect of summer passing . but the cooling effect is still really big compared to the street, which is bright red canada water. it was worth it happy. all right? yes. are there any other places where you think you could change a couple of things? yeah, of yes, one problem is that our office buildings are quite warm, letty farmers, and even more so on the production floor. sharlack is a medium sized family business that produces machinery. when temperatures outside your extreme welding can make the workplace seem like a furnace current malik wants to change that mental it is that high when it's really hot,

employees have the option of starting an hour earlier and leaving earlier in the afternoon. better working conditions. one thing, but if greener, industrial zones can reduce heat in the outer suburbs, it will also have an impact on the climate and the city centers. that's why the company aimed to gradually replace seal surfaces with greenery. anchor valentine, also convinced the young entrepreneur to invest in a green roof. the 140 square meter flat roof is well suited to provide natural cooling right next to the factory. as i can see, it's great that something like this is possible and these sorts of buildings or holt is one of 10 pilot municipalities aiming to transform new industrial straits as response to climate change. the i'm, you can, would, would be, well, what's, it's going to be a modular system here in another class. these boxes click together with just some

matting underneath. and when and the boxes will be lined up one after the other. if water, it's easy to see the advantage you normally rainwater would flow right into this drain. but this system can retain 20 leaders of rainwater per square meter fossil us. that's all god that will provide additional cooling. because the measurements show that the gravel, he was 29 degrees even with cloud cover. i think even these few plants a 3 degrees cooler. e v i v, i'm not sure. of course it would be ideal if there were greenery everywhere. i will have to speak to the neighbors again, dana tomato is working on a director vehicle. then it would have an effect on the street our. it's just the 1st step, like every little step helps you to manage that every little surface kind of the greening system, costs around $70.00 euros per square meter. with the council,

providing 10 is the subsidy. it's a start in other places, such efforts have long been standard practice the singapore government, supporting targeted efforts to bring nature back to the city. the city state is a pioneer. it's been greening high rise building since the 19 sixty's. mm. their gardens parks and greenery on all levels. architect thomas shrugged the research is the effects such buildings have on people and the urban climate. the unknown decor boy, the here at the interlaced complex, the arrangement of buildings contributes to optimal ventilation. the complex itself is already on a hill and we're also not far from the sea. off the i showed that there is always a very nice breeze passing through, which is used at the level of the complex as

a whole, to cool the outdoor spaces. but also in the individual apartment where you have really nice cross ventilation keeping the building. cool. before the crew, high singapore requires buildings to have at least as much green space as was cleared to make way for construction. otherwise, there will be no building permit truck for and his colleague also research the effects these green buildings hat society community garden for quite interesting. it's an extremely pleasant space for them to actually come together. they also do the thing about community cooking, where whatever produce, they go up there. so it's a nice way off engaging them. because accounts all of these green spaces are open to the public. so the residents from the surrounding buildings can use them just as much as the people who live here. yes, of course, that increases the value of the neighborhood is where these kinds of buildings are

located. origin toner, struck for works at the future cities laboratory at the singapore university of technology and design. during the pandemic post employees, a working from home they evaluate data collected from the building so often with surprising results themselves. from by fernando want us all, for example, we look at what bird species are found to us victories. and we find that in terms of biodiversity on buildings like these actually perform much better the size of oil. the course of this, even though they are densely inhabitants, and you also find a lot of bird species there that you wouldn't expect installed. mr. bach as well as great a bio diversity to buildings, helped to cool this surroundings. residents consume less energy and are able to enjoy new social spaces. dessert is a good boy,

doesn't mind about. i think these buildings are great examples of how dense and have a taishan can go hand in hand with quality of the space been up to one of irish. thus, germany can also look at this combination as proof that density isn't automatically bad for the environment. list for the most part, ideas from singapore can be applied to jim in cities, especially the realization that mo greenery is a good response to climate change. at central construction sites, motion belts is working towards a green, a city. this high rise building is getting a roof of plants using compressed air, the plant soil is transported to the 9th floor. a logistical challenge

bills is one of the $160.00 employees at a firm based in the city of hooper town, which specializes in these sorts of projects. just given out of everything will grow soon. right now it looks completely dry, like it's just dirt on top of it, but the material is going to store water and then slowly release that vessel gifted lung them up from dusseldorf to the cathedral city of cologne. the top floor of this plant hotel will eventually be a small, far saw the great 6 floors up with no elevator at my age. either holly against me today, i have to check the plant draws the gray plant and boxes on the buildings. ruth and sides will soon be house me to high plants. likewise, if all by anybody of the duma kinds of wood, it looks very good. oh, the drains are clean and tidy as plant. then there is nothing in the way of it. i'm

a, let's go around the corner again. yeah. belts is a meticulous planner. zima zip the 77 large trees were fuss about 380 smaller trees under since and a few 1000 shrubs and grasses and bushes and smaller plants of exit. to secure the larger order of trees, shrubs and bushes, belts heads to the netherlands. he's worked closely with the tree farm here for years. they share the same notion of quality. ah, this is no simple shopping trip, as well as martin belts in his colleague landscape architects and the investor are also involved in them with this. this is the north eastern side, or does the fears the tree right on the corner there on the account of home in that

position. it's an important tree. and beastie boggles fish on sophomore. let's take a look at it. it's this way. he's a victim. the tree farm covers a total of $500.00 heck tis. it's full generation family business. ah. was looking at the market. cool brigade is the resident expert fellow. he knows everything about his clients on the yeah, you can already see the fruit forming books on that stuff. it's a 35 year old metal, a tree, especially tolerant to hate. marching belts carefully selects the right tree from the long row. the old of the tree, the more expensive it is. they can cost several $1000.00 euros. so there's some hot bargaining good near to your there'd be an additional price of $8.00 or $900.00. was me additional? yes or no where? that's honestly, that wouldn't be good value, but he chooses another tree that they always come to an agreement. this is number

56 for now. yes. current cologne is heat, wave central. something has to change your cities won't be livable. any more. mm. the bill for the hotels trees is over a $100000.00 euros. good junky. oh, good. i guess i'm d. o a. the children of the st. marine kindergarten to stream could the 100 by one. and what are we going to catch that po? tadpoles. ok. now, or medi frogs with hon. about close me, the river im sure in the rue region. a few years ago it was a stinking concrete drainage canal. it's now been re wild it she made a lot of power, so i'll get a bucket full of water. oh look at what's hanging there.

adore it into the bowl. now my look, i got something here. i caught a baby nail. my, my, i get a magnifying glass. i is that a ripple bug. i often come here to cool down their shade and the water keeps you cool too. you can feel the difference on this mac when shown down in tennessee does this. yeah, man, you can see the kids eyes light up as they discover everything. you have a completely different quality of life when there's water around and the kids develop in a different way than 300 kilometers of waterways in the region of being rewarded

here. get daisy and there are so many animals here when i'm impressed that everything grow. so fast, yeah, i'm next. the one about is part of the regional project aims to make waterways contribute to sustainable calling. the kindergarten play area was specially designed by class yukon and only pet. so from the hampshire water authority, they saw that there was no reason for rain water to go into the sewage. instead, it floods the area and then slowly drains. so it provides both natural cooling and a cool place for the kids. i have to, if mom is enough, my hands are still wet from the hose and i can feel them getting cooler when i move them. a fossil, a 6, a crew to the water evaporates and cools them. it's your, it's the same principle with our seaboard system. but with that, water evaporates and cools what's around it, as long as you're, that's awesome,

that's what we're aiming for. to harness the water and keep it here. so it cools things down through evaporation. it won't, don't like to see until financials. good bye. to puerto a star, she wants to harness 25 percent of local surface water in this way by 2040, in an effort to keep residents cool. ah, the same principle is being used in town to next door to the kindergarten. water is channel directly from the church roof into a sloping meadow. rainwater is a natural air conditioner, even on busy streets, because of a chest into a chandel, germany's water management and the population in general are going to face challenges from increasing climate change drought. and significantly lower rainfall, especially in summer, via also in we're in danger of seeing drinking water being ration from co does as or not after long dry spells which of ice there may not be enough water to meet the

demands of industry agriculture. and the people sing, fossil fuel, knows many places in the rural region, a completely rethinking how they treat and use water for over a century. the m shoe was heavily polluted, but that's changing. the river flows from dorman through the rural region for 80 kilometers. before joining the rhine near didn't slacken in the future. waste water will be routed through a special closed canal. while everything else will find a different way. we haven't looked up. we moved just under 700000 cubic meters of earth during construction, and involves that of song guns or stuff. really pet sullen steph shuttle off from the am sure water authority. we're also working flat out to restore the rivers flood plain ne ohausen on the right of the plans. a somewhat revolutionary

jo sheets of we are. i'm unlike in the past like is all to days ecologists give an approximate meandering path and then hope that the river and the water will find their own way. i know vixen nature will do the work on it, and it will develop on its own animal. fortunately dish deputy national to spend the last 6 years rehabilitating the river the for the by forwarding plan for this is where the little ringed clover came to visit us on the building side of the syllabus. and i had nested and bred successfully rooted, a foreclosure on how to boast when it had gone again, we could keep working on them. so we do things hand in hand with nature on every step of the way should 1st within a few years, flooding will take place and perhaps the cooling flood plain reaches far as ohausen . ah, i can dusseldorf, the 30000 wound being bushes getting

a last prune that survived the haste of if this summer if the leaves are starting to turn a bit, the shoots are battling great. um he did with his implants to help cool is it he seems to be working with architect crystal in and home is placed in front of them under the hood an item of was it that to resolve the left out on the, for the city of diesel doff has many facets even then, especially when it comes to the dramas of post war west germany. they got them gunston drama. fis deutsche and knock creek reconstruction. the new buildings going up in the fifty's and sixty's. oh bout lloyd bowed for sale. they say i want it's clear, the city could use a lot more greenery on just like every german city or, or every city full stop yourself. there's no city that couldn't do with a few 1000000 more trees. people just have to push for it. well then it will happen a bit. this bus. yeah. the clock is ticking. made catastrophic climate change out

in a cities can only remain livable with is a massive shift to ports, new green ways of building with

who freedom and security are essential to their way of life. but how is that affected by their proximity to russia? let been verified as the happiest people in the world. most of them believe in peace. but would that change if there erratic labor is feeling for those

3? 15 minutes on d. w. on the green fact that you feel worried about the planet to? i'm the host of the on the green fence post and to me it's clear we need to change . join me for deep dive into the green transformation for me, for you, for the plan with. ah

ah, rearing to read. ah, everyone who loves books has to go insane. ah, the dw literature list, 100 german must reads ah, it's a race against time. how quickly can vest on countries cut their reliance on oil and gas from russia? the united states, north dakota is the 3rd largest oil producer. and here the tensions playing out in the energy sector are on full display. will the clock be turned back? there is a greater voice for fossil fuel or low green energy can real momentum. we call the

saudi.
