people on our planet one to live in cities, it's access to cutting edge facilities higher b, better education to name just a few that makes city living attracted to so many of the un estimates that for more than 75 percent of the world's population. this will be a reality by the year 2015. how are cities preparing for this search? what needs to be done today to ensure that cities of the future are environmentally sustainable? that's what we'll talk about today. hello and welcome to eco india. i'm some of that i call lead start in a city i call who will buy more, more land in discourse to metropolis is being used to build residential complexes and office spaces. there's been a 62 percent increase in mobile population in the last 3 decades. a trend that's expected to continue. one of the impending questions is this. how are we going to

ensure that so many people have enough food to eat? and organization in the city is helping people do their bit to tackle this inevitable problem? the can to marsha fairly, albert is and her team. the 1st stuff is to clear that andrew day preparing the ground for the planting off to meet those chillies. be nuts and molla bar greenwich, the groups current. workplace is the grounds of a school in the middle of my bike. here are the environmental activists are setting up the latest food flores. why we need to compensate for the amount of concord days ation is that is happening. so we want beto, where we want to know everything, you know, that can happen automatically by itself. and it can automatically happen when,

especially when a lot of the see and a lot of for, you know, open spaces and what used to be, you know, green color is being taken away. the average temperature in move by has risen noticeably in recent years. that's mainly because the city has lost around 40 percent of its green spaces over the past 3 decades, along with one 3rd of its water bodies. at the same time, the built up areas have expanded by 66 percent. the food forest, which usually cover just small areas, are designed to recreate green with it all over the city. i definitely think that a full forest is an effective solution for the city because it's all, you know, creating an ecosystem by itself. adding, adding a lot of value to the green gobble, it's going to benefit a lot of fall bonds and people a sudden pencil livelihood, depending on them. the food was well conceived by georgia may deals,

and his nonprofit organization turning died. he decided to take action at 6 years ago after his mother developed respiratory problems from the poor. quality trees was something that i was attracted to as a solution to try and fight back the feeling a quality and i decided on the food for us concept. mainly because a food forest is based on a natural living ecosystem. although it takes a few years to establish, we regenerate the soil, we lea, generally the landscape. there are various ideal locations for a small pool of water in the middle of the oven jungle, from open spaces on the grounds of school, and often ages 2 strips of land between apartment blocks. this is the color neighborhood near the city center, measuring just 4 meters wide by 44 meters long. this water sniffling between buildings was established several years ago. the planting follows us specific

system, so that about 8 different layers of food use out of the are. you going to shorter to bush's shrubs grass layer, herbaceous layer root lids, that creepers and in certain bases are even the fun. and also, you know, the layover, you have water plants as well. because the main idea is to try and cover the surface of the us with some form of root system. that's east of the water infiltration and some kind of govern lansing of food costs between 15 and 30 pounds and will be all around 360 euros. the work is mainly finance, so donations once it's been set up as events and volunteers help out with the upkeep, the forest side essentially biodiversity, heart sports for insects and birds and logos benefit to in gov either. i mean, like he already, the advantage of having a food forest is that we have free access to all these fruit on it. it's quite

incredible to have this option in this, in the middle of a city like them by email. and it is especially good for the younger generation is up, was cough either. georgia medial is provides regular updates on social media. used to work in the advertising industry, but gave up his regular job to focus on the forests. in this post, he explains the principle of food for us and how it can help with waste management . in a ford forest, i can manage literally tons of wrist. we've taken over 5 tons of bio mass from the surrounding areas and we've done this thing called b marching. for most is basically like a cover like it's like having clot over your skin. it protects the soil, reduces the evaporation as it breaks down and degrades. it forms composting forms, nutrient rich layers of soil, and a habit that for all kinds of creepy girlies,

which we considered as best friends as they break everything down and create new layers of sight. lots of saplings i needed to plant up the forest. and here to there are plenty of volunteers willing to help grow you like me. and then what i didn't use is the balcony of an apartment number my family to nurture to me, doors to leave and being a plant ready for planting. i. they did decide because newspaper being alive and i am very fond of reading newspapers i came across i because i contacted him say want to be a small side of this big movement despite on the hill, it hadn't been easy for george remained us. some of the plans in the forest have died because they didn't get enough water, but his texas shows he's on that i boss. he's already planted 12 o'clock noon by

with many more plans for the future. now if you are a resident of moon by like me, dealing with torrential reasons is a part of life. but in many parts of the world, climate change among other reasons is causing unseasonal and heavy reasons where the forecasts often provide a reliable update for the wider geographical region like a city, state or country, but may prove unreliable for smaller geographies. a scientist in germany is now developing a new more precise e i supported reentry dot rubato visited him to find out how it works. one day in 2018 you leon hoffman rushed into central arkwin on his bike, a storm cloud scattered overhead of him. badani zane and monterey institute's weather radar and by the time i reached the city center and they were already

a few puddles of water and then the storm really hidden, i just half an hour later, most of the inner city was flooded. a laza, a hydraulic engineer hoffman, his meeting. maximilian knew sla from the arc and fire department on that day. he was one of the 1st to arrive at the scene. towns and villages across the region were flooded. in a matter of minutes, the emergency services were overwhelmed with calls and struggled to cope. if these birds eaten nature shows how much damage flash flooding can do right now, we're at kaiser plots. you can see that the streets here were completely flooded. drive us were taken by surprise in a situation like that, it's not even possible to important off the streets in china. we never know with the rain will be heaviest and what damage will cause. we also, thanks to technology developed by you leon hoffman often is the 1st german city with a risk based early warning system for plu, field flash floods. first,

he used to drone to create a cartography of the entire city. the heavy rainfall simulation shows that water flows to the lowest part of the city, the kaiser plants square. the data for the pilot project is supplied by a weather radar house in an industrial park on the outskirts of the city. and from there, it's a midi relaunch. decal gauge to measure or estimate rainfall or other forms of precipitation in a given area. funny ego or another need are flux oper, donaldson yet. and the way it works is it emits a signal that interacts with the precipitation and then relate back to the radar. on done, we don't follow that from either. this data allows you leon hoffman to make a precise prediction about which areas will be most affected. nas, cancer, come and, and you can see it very clearly when you look at the simulation and evaluate it.

this is rosetta secondly, the water flows along the street and goes around bends. when t o, my finances, i know is, here is a small traffic island which is factored in wood fixture. the water flows along it and then reaches a local low point on. so num lakaya teeth, this is the vest bonham station and under past that was flooded in 2018 and rendered inaccessible. mab, fabiola such an early warning system could be hugely beneficial in countries like india, where extreme rain of answer increasingly common flash flooding is a bigger threat in india than in any other country in the world. apart from bangladesh, here late inside monsoon periods, obviously have to be taken into account here. they're few langer words i time of these are much longer stretches of heavy rain. tom was under his asthma day and i could set side and the model should still be able to provide short term predictions about what the system would 1st have to be modified on movies. first hoffman plans

to calibrate it more precisely to conditions and ask him he's working together with the city of authorities and the emergency services we've got a if a hospital is affected or a private home where exactly and with the water will be making no super. it's not, it just needs to be formulated in simple terms or transition. so no meteorological jargon, property terms. everyone can understand that. and it has gotten bozeman, for example, 50 leaders per square meter, littleton, colorado, in or low water level of so in so many centimeters in your home. and that's what owns as far couldn't really help the fire department. and the general public hearing are often any little soon posits, and they can refer to the map and the forecast lock to prepare for an event. every city faces different challenges and there's no silver bullet against climate

disasters. but with his early warning system, all him now has a tool to tailor its response to any future flooding. imagine say now normally is oil and gas made the relatively small european country veggies rich law regents on more money compared to other europeans. the capital city also is a small city. about 700000 people live here. most of them like all slower because the city has invested a lot to become environmentally sustainable over the us. as low as one of europe's fastest growing cities, a challenge the norwegian capital is meeting with, among other things. innovative architecture also changed radically. the last 20 is um, the cars has been taken out of the city center. and there has been build a lot of cultural buildings as well along the harbor main menu. and then it's

become a more lively, open and welcoming city i, i suppose, architect anna, muddy. linda has been watching the development of aust, lowe's urban planning for some time. right. up to the late 19 ninety's shipping containers and heavy traffic dominated the bureau to be go waterfront quarter to 8 people culture and the environment take precedence. one example is the diamond bureau to pick a library. the building causes very low emissions and thus meets the norwegian, passive house criteria. it's 6 floors offer a variety of spaces to work and study in some feel like an urban living room. it's a melting point, a vibrant, hopeful, the citizens of all slow. everybody can come here, but it's also m sustainable in the way it's built, but also like you can't park f when since you have to use public transport. that so many aspects within the, which is really sustained, not far from the library in the neighbourhood accurate, but again,

is the new national museum. the facade is covered with norwegian slate, a highly durable natural material. pass low plans to become climate neutral by 2030. among other strategies, the city has a mobility concept that favours bicycles and public transportation. there are purchase subsidies and lower vehicle taxes for electric cars, as well as a good e car sharing infrastructure. another showcase project is bulkhead. it used to be an industrial park, but now the area is car free with energy efficient, residential and commercial building, and a market whole with an integrated power plant that generates energy for vulcan from geothermal and solar panels. what's really special about the can is that it's, it's a city within the city and it's a mis mixture between the re use of old industrial architecture. and then

i mixed with new buildings. so it's kind of a really vibrant tub within our slow. i'm with this remarkable mixture between you and old animals also stand to benefit from maslow's green strategy. the keeper, alexander dorothea, keeps 45, hives on os. lowe's, roof tops, thriving bees help keep ecosystems intact. a so called b highway runs through our slow supplying pollen for the bees that be highway a works like that. we have a plant, it be friendly, flowers in a inner road as crossing the whole slo seat the centre. so that beast can ne, flying around dead without to a get problem to find day. and nick resources that we have in other cities can learn a great deal from oslo banded sustainable concepts for the future trick

allah was an average town in greece with about 60000 inhabitants until it got a new mayor in 2040. he started to change it into a modern smart city. jones for transportation of medicines, are being tested, intricate at the moment, and apt to connect the elderly and disabled to caregivers is being tried out. we visited the city to find out how technology is helping solve solve its common problems. tree killers mad demetrius papist a. you won't let an occasional internet crash canter him. not even with a delegation from his german sister city looking over his shoulder. they are gathered in the town halls control room from here. the 1st smart city in greece is operated. local ross of the german guests are impressed.

ben, yes, over in from a computer scientist myself, and to be honest, there a step ahead of us. we can learn something from them. this was my was was on the can and v lennon. from here, the staff can monitor how many parking spots are occupied. the municipal water pumps power usage for the street lighting, and even how full the dumpsters are. puppets to you is aiming for a green and energy efficient town. he admits he'll need far more than a high tech control room in the book. you know, this isn't just about new technology, is what it's about, a new way of thinking that we need here, increase your discipline, we've seen, or the old thinking got us, you keep up with me. for example, breaking the habit of going everywhere by tom mer passed. are you rides his bike, where he can? 3 colors become known as the countries bicycle, friendliest town. the otherwise of age, community of as an $80000.00 in the central greece is exploring other tech

solutions such as the electron mobiles, the man brought in for the towns. officials a modest 1st stamped towards what he envisions as a greek silicon valley. ah, after was, wouldn't you know, we have the advantage of our central location and greece, man, i'd like to see young creative startup, settle here, usually with the right thinking we can stop to migration to the big cities. and when the young people back to push booming his women, george's crystal moto says in the vanguard of the young tech elite, he's helping the regions farmers achieve better crop yields. there with gun measure all the humidity that a lady from me to deal with atmosphere. there she made it the in the soil, the temperature here, the bottom of the pressure and cover customer solutions for the farming. and because we have the mayor that these open minded that to keep them as you ac at the town hall, the open minded man is showing his guest from. i'm back the next innovation,

a machine for printing official documents and forms. for now, it just prints tests sheets. the greek government won't accept electronic signatures. this also left the, instead of supporting us as a government and it's agencies are always tossing wrenches in the works that the muslims could. so we try to find ways to get around the government agencies and we're not going to let them slide down the ideas to make dealing with the city government. unlike the federal agencies as an bureaucratic, as possible for the people of tree color. whether applying for building permits or marriage certificates. every email receives a prompt answer like a given i thought my application by internet and i picked it up today completely processed. citizen services also play a major role in parking in town. drive is confined and pay for parking spot using an app tree can, i won't be resting on its laurels. a self driving mini boss will be in service here . ideas like these have brought praise for tree color and money to energy

and cost efficient management of help the town reduce its dead burden by almost half 3 can i is setting an example for the rest of greece. the way out of financial crisis is the smart way. those of us who live in concrete jungles understand the value and the need from green spaces, box and gardens help improve a quality and a micro climate of cities. but in wyoming real estate markets, and with soaring land prices, their de privatized an alternative to create green lungs in cities may still be available. let's see how this design a hotel is a green oases in the middle of the german capital. it features a garden in the courtyard, plants on the roof and ivy on its facade. the project is the brainchild of berlin bass architect you oh, elmwood grin, to answer. and amanda grew into the gotten excited garden also has

a nice climate to touch. very quiet here inside the courtyard and the humidity is pleasant for. he can only have the moment you walk in it, does you good? oh, the stablish man is said to open soon as a hotel in the center of bill in it used to how's a detention center for women and juveniles. this form of prison wing is now the hotels corridor. all state prison cells have been turned in some modern hotel rooms . traces of the past are visible everywhere, and the building is classified as a historical monument. of course, you need a great deal of sensitivity and you have to make a lot of your case by case decisions about what to keep on what to change and how to change it. the be the most crucial part was the moment of transformation, creating a positive atmosphere and banishing the element of fear in the buildings is on for months and i'm calm shafts we above in the numerous plants and trees create an

update ambiance inside and out. the architect, you are deliberately incorporated them and they cover nearly half the surface area . and then he'll want a shot. if you look down here, you can see how we've added plenty of greenery to every space possible. as we've removed courtyard flooring and planted vegetation. and it benefits the whole urban ecosystem. when architects build new buildings or convert old ones, this way i can abide mom. and the coach out of a architecture firm is very green to the jew. a has been collaborating since 1991. in addition to studying the impact of plans on people's well being and the environment practice, they also instruct theory at a university. palmetto grew into and even wrote a book about the topic, entitled quoted texture. the term comes from the latin word for garden, ho tooth and the english would architecture hashed in edison. probably him have, it's clear, there are problems. he stays with lots of rainfall, for example,

and air quality. and so it's just nice to encounter places with nature in our private lives are at work. it boosts our quality of life, limbs, quantity to us on the architecture means not just incorporating plants, but consisting of plan ah, out plants. green architecture is also meant to protect the climate. one famous structure is the bosco, vertically or vertical forest. the milan, italy, boasting or the $900.00 trees. it was conceived by italian architect stephano bodhi . ready across europe, visionary buildings are springing off where plants play a major role like the grained waste incineration plant. a coven hill in copenhagen by danish architect, bianca ingles, or curb bergen sy, in dusseldorf, by german architect, chris of england. hovan. a building shall holding 30000 hedges across the globe designs by the single po based whoa ha, aquatics shine as green superlatives like this multi story luxury hotel with

swimming pool conceived as a grain oases. right in the middle of densely populated cinnapool back in berlin. the latest project by green to answer is a public park on the top of a private building. construction is about to begin with. it has it in no global. it's really a global challenge. and that's why there are architects worldwide tackling at a net. and i think we should network more. ok, i want to develop strategies together to better address the need to add extensive green spaces to building. i'd like to incorporate these demands and policy making world wide. and they all stand to benefit quote, to texture presents a sustainable architectural style for the cities of the future. ah, the time to build green spaces is now the time to use technology to foster environmental sustainability is now the time to act on moving away from fossil

fuels is now i hope this episode has given you some perspective on how environmental sustainability in cities is possible and already under way, i'll see you again next week with many more such thought provoking stories until then goodbye, and thanks for watching the news. news . news. news. news. ah, ah. with
