green building society community garden. 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 grow up to. it's a nice way of engaging them. all of these green spaces are open to the public and the residents from the surrounding buildings can use them just as much as the people who live here, of course, that increases the value of the neighborhood where these kinds of buildings are located on thomas trotter works at the future cities laboratory at the singapore university of technology and design during the pac gimmick, most employees are working from home. and i evaluate dr. collected from the buildings often surprising, resolved themselves on their own does. for example,

we look at what bird species are found to expect, and we find that in terms of bio diversity, buildings like these actually perform much better. besides the boy nicole was this even though there densely inhabitants, and you also find a lot of bird species there that you wouldn't expect this about as well as great a bio diversity to buildings help to cool this surroundings. persons consume less energy and are able to enjoy new social spaces. ah, he's a boy, doesn't mind them. i don't. 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 is does. germany can also look at this combination as proved that density isn't automatically bad for the environment. for the most part, ideas from singapore can be applied to german cities,

especially the realization that more greenery is a good response to climate change. several construction. so it's motion builds, it's working towards the green. a city high rise building is getting a roof of plants. using compressed air, the plant soil is transported to the 9th floor. a logistical challenge. fills is one of the $160.00 employees that assume based in the city of charlotte, which specializes in these sorts of projects. you would, 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 them from the door to the feet

of the top floor of this plan to tell eventually be a small the go, the great 6 floors up with no elevator at my house. i can see today i have to check the plant trons. the gray plans and boxes on the buildings roof and sides will soon be help me to hi plan all by me with a demo it looks very good. the drains are clean and tidy as planned. there's nothing in the way. let's go around the corner again. bill is a meticulous plan or even a zip fish. 77 large trees with us about 380 smaller trees and a few 1000 shrubs and grasses and bushes and smaller plants of exit. to secure the large order of trees, shrubs and bushes, heads to the netherlands. he's worked closely with the tree farm here for years.

they share the same notion of policy. ah, this is no simple shopping trip, as well as martin belts and your colleague landscape architects and the investor are all involved in this. this is the northeastern side. here's the tree right on the corner. in that position, it's an important tree and sean, so let's take a look at it this way. he's, it took me the tree farm, covered the total of $500.00 full generation family business. ah, in the old market. cooper, the superintendent expert, he knows everything about his lance. you can already see the fruit forming books on

that. so it's a 55 year old military, especially tolerant to have. martin bells carefully selects the right tree from the lower row. the old, the tree, the more expensive it is. they can cross several 1000 euros. so there's some heart bargaining. it's here. there'd be an additional price of $8.00 or $900.00 additional. yes or no way. that's honestly, that wouldn't be good value, but he chooses another tray that they always come to an agreement. this is number 56 for now. yet, colonial heat wave central. something has to change or cities won't be livable anymore. the bill for the hotel trees is over 800000 euros. and d o j o. this

will give the children of the thank marine kindergarten to stream put the 100 and what are we going to catch that? pearl tadpoles. ok now, or maybe frog one about flows. neither is an issue in the region. a few years ago it was a stinking concrete drainage canal. it's now been re walled it a lot of power, so i get a bucket full of water. oh look at what's hanging there for it into the boat. yeah. yeah, yeah. my look, i got something here. i caught a baby sales get a magnifying glass. is that a ripple bug? again,

that often come here to cool down shade and the water keeps you cool. who you can feel the difference on this map when shown down. they don't include, you can see the kids eyes light 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 course, wait in the region, the re while they get this. yeah. and there are so many animals here when i'm impressed that everything grow so fast, i'm vicks the box as part of the regional project that aims to make waterways contribute to sustainable cooling. yeah, that's the kindergarten play area, was specially designed by clowns, yukon, and only pet. so from the mc 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. and i hope the energy warm it's enough. my hands are still wet from the hose and i can feel them getting cooler when i move them 1st. so the water evaporates and cools them. it's the same principle with our system. we said water evaporates and cools what's around it. it's nice to me, that's what we're aiming for. to harness the water and keep it here. so it cool things down through evaporation. don't take us here by the fortress. she was 225 percent of local since the water in this way by 2040, in an effort to keep presidents. cool. ah,

the same principle is being used in town to next door to the kindergarten watery channel, directly from the church roof into the sloping meadows. ah, it's a natural air conditioner, even on a busy street chest into i shan't on germany's water management. and the population in general are going to face challenges from increasing climate change drought and significantly lower rainfall, especially on summer via we're in danger of seeing drinking water being ration. i'm come that's as well. not after long dry spell. there may not be enough water to meet the demands of industry agriculture and the people thing for us for, for food on as many places in the rule region a completely rethinking how they treat and use water for over a century. the em, she was heavily polluted, but that's changing. the risk flows from dorman through the

will region for ac kilometers. before joining the ryan need in slack and in the future, waste water will be blue sheet through special close canal. while everything else will find a different way to look it up, we moved just under 700000 cubic meters of earth during construction in boston. so you got us from pittsville instruction often they should water. so she's also working flat out to restore the with the flood plain me. oh, the house on a white of the plans. it's somewhat revolutionary. interesting. so unlike in the past, today's ecologists give an approximate meandering path and then hope that the river and the water will find their own way. i know the nature will do the work and it will develop on its own animal. fortunately, this step she tested to spend the last 6 years rehabilitation of is up to

forward in class. this is where the little rings. clover came to visit us on the building side of the she's missing. i did method and bread successfully booted a focus on how to box it had gone again. we could keep working on so we do things hand in hand with nature on every step of the way she was with them. but if you, he is flooding will take place and perhaps the cooling floodplain reaches far so the house and ah, i can do some of the city sounds, moonbeam bushes that getting a last prune that survive to have their 1st summer leaves are starting to turn event shoots are better than grain. ah, he's in class to help cool. the said he seems to be working. architect crystal is who is placed on just as an item was

either 3 of us and the city of decile dog has many facets. even then, especially when it comes to the drama as opposed to war, west germany, duncan, but i'm back the reconstruction. this new buildings going up in the fifty's and sixty's. oh bout lloyd bowed for element. it's clear, the city could use a lot more greenery, just like every german city or every city full stop use that there is no city that couldn't do with a few 1000000 more trees. people just have to push for it, then it will happen and that the stuff in the clock is ticking me catastrophic climate change out in a city can only remain livable. there's a massive shift towards new greenaway building. the

the news. the news in africa. the great marine law and the hell when it's finished, it will be more than 15 kilometers wide and a 1000 kilometers long. a nice green thread to combat deserved vacation. what's been accomplished since 2007. how can the initiatives be improved?

we talked to the projects director incentive on the far out in the north, the germany's only island on the open sea. a day trip is nice, but it's better to stay 2 or 3 days on the island that makes the real difference is the ideal place to slow down and check in in 16 d, w. o. the, it's about billions. it's about power. it's about the foundation of the world order, the new silk road,

china to expand its influence with this trade network. also, china is promising its partners rich profit. in europe, there's a sharp warning you wherever accepts money from, the new super power will become dependent on in china's gateway. year starts july 1st on d, w mm . the welcome to another edition of africa. you'll be hearing about some very special people in today's program. i am under 3 of you and jane by my co presenter.
