ah, most people and nature are experiencing extreme temperatures and drought in our cities each year threatens to bring record hate jump to. we've measured 70 to 80 degrees celsius on glass and steel mill behind here it might be 30 or 30 by the dense development concrete. an ash melt become dangerous reservoirs of hayes. it's nearly impossible to cool them down because in the understood, it's a city of facades which reflect, reflect, and tend to make the problem worse. problems here goes off. high temperatures, threaten now health. we need to cool down as ice. bear for 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.

with russian builds is 27 meters above ground working on europe's greenest, high rise barracks is a passionate god, not with his green facade. he's providing a natural air conditioner in the heart of the city. if runs and fun gets annually, the leaves are starting to retract and slowly dry out. none. but thanks to our watering system, a vessel there are also fresh usa clever become mm . this shopping center is called crude bogan, to named after diesel dose coon, exactly shopping area. the 30000 horn beam plants said to call to building to hampton noise and absorb carbon dioxide in their 1st summer plant. so already

feeling the heat, their part of an effort to counteract increasing heat waves in gym in cities. a consequence of climate change. the whole means of only be for 6 months. so this still new, this applied by a special irrigation system all nearly $35.00 degrees. has it running with 5 leaders a day for the tubs, and 15 leaders per square meter city, michigan, to muster outside. what's that red outage most for the august? i'm sure 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, a here. but it has enormous benefits to city residence. worth of, of that water gets turned into cornell woman. 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 and unlike a condition of the plants don't blow out hot am to the city heat increases have been traumatic from 1961 to 1990. the average for july was 16.9 degrees celsius in the city years after that, it was 18.3. an increase of 1.4 degrees, vamped in part one of glass in high summer. we've measured about 70 to 80 degrees celsius on glass and steel shuttle behind. here it might be 30 or $35.00 degrees at 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 from the ice because the cells would burst them and the moisture would cool things down again. city. but

that's also why they have a cooling, a fax of us. it's just how nature works. so i feel fortunate not one night you too can experience suffering. and martin belts and his team still have work to do with the home the implants, a few kilometers away at to source riverport, the landscape gardener is working on another project he meets with architect christ of engine hovan. he designed to put a boat in 2 people with him on fort la re mcnair. how 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 visit i might inflicted some helps to pay. i have completed many projects together for me 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. and how's balling, did you, 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 well d. 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, nation forces management. so if we evaluate the ecological and social value of the nature that would otherwise be there, than we have to do something that compensates for us toward does docile to as long as it's like the roof with the horn bean plants. but it's not just city centers. chimneys industrial zones need to become created to research is in once to land are about to take to the sky. and what's the humidity you push to 90 percent, cynthia 90 percent. and evie schneider is doing a final with a check. it's going to be hot and humid day perfect. the head project, the measurement engineer is going to fly over some specific industrial areas.

it from the it should use a thermal imaging. can she get precise tonisha 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 bone summit shop 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 does the alcohol, you can see that there is no cooling left. that's frightening, less if you can tell what a built up area is 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 the

thermal images, a precise with cooler areas, blue and hotter parts red. down on the ground, uncle valentin is in the book 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 increasing the affects, the people who work here too. in germany around 56 hectares of nature and countryside and lost every day. that's the size of $76.00 football fields. the

government had aim to reduce this figure to 30 hector by 2021 that's now been postponed to 2030. this wild plant bed was only planted in the spring. and co valentine is here to make business owner cotton sharlack and gardner t. o. grunge, timor, very good to see if the plants have already made a difference. more at off, my ross on, let's see what the airplane brought us have the read or it is, the harder it is. is the highest. and we're here. here's the bed on it. oh yes, nice and blue. oh, oh money i understand. um you might think its 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 that's what it is that high when it's really hot, employees have the option of starting an hour earlier and leaving earlier in the afternoon. it's occurred 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 in 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. without guns, it's great that something like this is possible and these sorts of buildings. oh holt is one of 10 pilot municipalities. i mean to transform new industrial states as response to climate change, young kim would, would be well with it's going to be a modular system again and i get like these boxes click together with just some matting underneath and wendy's a kiss. 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 meters, roughly. that's all got it. that will provide additional cooling because the measurements show that the gravel he was $29.00 degrees even with cloud cover. i think even these few plants

a 3 degrees cooler. e ivy, 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. it's just the 1st step like every little step helps eda, banish that's fair, 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 1960 s mm.

their gardens parks and greenery on all levels architect tolmas shop. the research is the effects such buildings have on people and the urban climate. the unknown data over 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 ice cream off. the usher that there's 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 apartments. where you have really nice cross ventilation keeps the building cool to support through ha, ah, 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 shop 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 draw up there. so it's a nice way off engaging them because 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 thomas short for works at the future cities laboratory at the singapore university of technology and design. during the pandemic post, employees awaken from home they evaluate data collected from the building so, so often with surprising results themselves from buyers for them. they 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 boy nickel was a dish, even though there densely inhabitants. and you also find a lot of bird species there that you wouldn't expect, or mr. bar 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 a man. 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. shift. 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 builds is working towards the greenest 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 a $160.00 employees at a firm based in the city of hooper, child, 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 the material, is going to store water and then slowly release at russell gifted lung them from dusseldorf to the cathedral city of cologne. the top floor of this

plant hotel will eventually be a small, far saw the great explorers. up with no elevator admired a hayley gun suite. a day i have to check the plant draws through the grey plant and boxes on the buildings. ruth and site will soon be house me to high plants. likewise, if all about me, body of the dim arkansas wouldn't, it looks very good. oh, the drains are clean and tidy as planned. then there's 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 and a since and a few 1000 shrubs and grasses and bushes and smaller plants of exit. to secure the large 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 theory the tree right on the corner there on the account for me in that position. it's an important tree. and beastie boggles fish on sophomore. let's take a look at it 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 the folks on that. so it's

a 35 year old metal, a tree, especially tolerant to hate martin belts carefully select the right tree from the long road. the old, the tree, the more expensive it is. they can cost several $1000.00 euros. said this some hot bargaining. gooding it's your, there'd be an additional price of $8.00 or $900.00. was me additional? yes or no way that 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, junkie. oh, good, james. again, i'm d. o a.

the children of the st. marine kindergarten to stream could the hun and back up and what are we going to catch that po? tadpoles. ok. now bore medi frogs with hon. about close neither river m show in the 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. i'm sure it into the ball. yeah. i look, i got something here. i caught a baby nail. my my, i get a magnifying glass. i is that a ripple bug? i again that i often come here to cool

down. there is shade and the water keeps you cool too. i can feel the difference on this one. shouldn't even touch it. does this? yeah, i mean 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 re while did you get this? yeah, 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 cooling. 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 the islam, it's enough. my hands are still wet from the hose and i can feel them getting cooler when i move them a fast. so the fixer cooler, the water evaporates and cools them, it's your, it's the same principle with our seaboard system for doing that. water evaporates and cools what's around it. as i showed us, assume 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 like to see until fossil school by the portraits are. 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. give us over just into 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 the we are in danger of seeing drinking water being ration from come as us or not after long dry spells which of ice there may not be enough water to meet the demands of industry of agriculture. and the people think 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 close 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 involved that of song against us. legally pet sullen steph shots off from the am sure water authority. we're also working flat out to restore the rivers flood plain ne ohausen, a traditional white of the plans, a somewhat revolutionary sheets of we are unlike in the past. like as all today's ecologists give an approximate meandering path, and then hope that the river and the water will find their own way. i'm going vixen . nature will do the work on it, and it will develop on its own animal. fortunately dis, deputy national has spent the last 6 years rehabilitating the river the for the price forwarding plan for this is where the little rings. clover came to visit us on the building side of the syllabus and i had nested and bred successfully

concluded a focus on to how to boast when it had gone again, we could keep working on. so we do things hand in hand with nature on every step of the way. we should 1st with on board in 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 better than great. um he did with his implants, to help cool is it he seems to be working with architect christopher in home is pleased one moment of an item um and was it not resolved just not on the for the city of diesel. doff has many facets. eden,

especially when it comes to the dramas of post war west germany. they've gotten guns from bahama, this deutsche not creek reconstruction. the new buildings going up in the fifty's and sixty's. oh bout lloyd bowed for sale. they say our mud, it's clear, the city could use a lot more greenery on just like every german city or, or every city full stop usa. 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 and that this bus you the clock is ticking me catastrophic climate change out in a cities can only remain livable with is a massive shift to put new green ways of building

with with the war has forced more than 4000000 ukrainians to their country, like a 36 year old business owner who left to the company and employees behind people who continue to rely on him for a salary. will his enterprise be able to survive the war? a d w business special quickly. next on d,

w. and to the conflicts own with tim sebastian pressure allegation with cranium pavilions outside of rock with russia really care what the world with i guess with very few other conflict in 60 minutes on d. w. with a more and eternity time. it can be measured precisely.

and yet every one experiences it differently as if there are different forms of time. time, a phenomenon, a dimension, if we know we won't live forever, an illusion. about time presenting future's past starts april 14th on d, w. ah . abandoning nearly every thing a fate death, millions of ukrainians have had to encounter so far. on the show, we meet a filmmaker who managed to flee the war and is now worried not only about his business, but about the lives of his employees to 70 percent, or fill in a crate or against some of them. i.
