dot com ah ah, most people on our planet one to live in cities. it's access to cutting edge facilities, hire pate, better education, to me, just a few that make city living attractive to so many of the you an estimate that for more than 75 percent of the world's population, this will be a reality by the year 2015 how was it is preparing for this search? what needs to be done today to ensure that cities of the future are in was mentally

sustainable. that's what we'll talk about today. hello and welcome to eco india. i'm sorry. 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 more shalley, albert is and her dean. the 1st stuff is to clear that our base androids preparing the ground for the planting off to meet those chillies,

be nuts and mala bar bridge. the groups current. workplace is the jones of a school in the mid last. mom by here are the environmental activists are setting up the latest food forest. why we need to compensate for the amount of concord days ation is that is happening. so we want that all where though we want to, you know, everything you know, that can happen automatically by itself. and it's gone automatically happened when, especially when a lot of the sea and a lot of for, you know, open spaces and what used to be, you know, green cover is being taken away. the average temperature in mom 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,
3:05 am
which usually cover just small areas, are designed to recreate green with all over the city. i definitely think that a food 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 grim gobble, it's going to benefit a lot of fall bonds and people and hence livelihood, depending on them. the food products were conceived by georgia, my ideals, and his non profit organization turning died. he decided to take action 6 years ago after his mother developed respiratory problems from the poor qualities. threes was something that, you know, i was attracted to as a solution to try and fight back the feeling a quality and i decided on the food forest 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,
3:06 am
we regenerate the landscape. there are various ideal location for a small pool of water in the middle of the oven jungle, from open spaces on the ground, a school, and often ages 2 strips of land between apartment block. this is the call a 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 a specific system, so that about 8 different layers of food. you start off with your tall trees, you go into shorter trees, bushes, shrubs, grassley, habitually, the rootless. there are creepers and in certain places as even the family. and also, you know, the near where you have water plants is when was the main idea is to try and cover the surface of it with some form of a root system that sees to the water infiltration and some kind of cover planting
3:07 am
of food for it. cost between 15 and 30 pounds and repeat, or around 360 euros. the work is mainly financed through donations. once it's been set up, residency volunteers help out with the upkeep. the forest sad, essentially biodiversity hot spots for insects and birds and locals benefit to go pilots. i mean like the idea of the advantage of having a food forest is that we have free access to all these through it. i think it's quite incredible to have this option is in the middle of the city like combined it's up and it is especially good for the younger generation is a was cough either george remedial is, provides regular updates on social media. he 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
3:08 am
. in a food 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 mulching. so much 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 compose to forms nutrient rich layers of soil and a habit that for all gains 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 me. and then what i didn't use is the balcony of an apartment number to nurture to me, doors to leave and being a plant ready for planting i there. but just because in newspaper being alive
3:09 am
and i am very fond of reading newspapers i came across, i because i contacted him say wanted to be a small part of the 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 ice boss. he's already planted 12 o'clock noon by with many more plans for the future. now if you are a resident of room 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. rebuttal visited him to find out how it works. one day in 2018 you leon hoffman rushed into central arkwin on his bike. his storm clouds gathered overhead, open badani zane and monterey institute's weather radar with one. by the time i reached the city center and there 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 lava, a hydraulic engineer hoffman is meeting maximilian new sla from the arkan 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 struggle to cope. of these

birds either sunday church shows how much damage flash flooding can do right now we're at kaiser plot. 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 horton off the streets in china. we never know with the rain will be heaviest and what damage will cause. 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 of her. it's a meaty relaunch decal. gauge to measure or estimate rainfall or other forms of precipitation
3:12 am
in a given area. funny ego, what are some of them need are flux oper? dustin and yet in 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 radar. this data allows you leon hoffman to make a precise prediction about which areas will be most affected. no guns common 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 ben's when t on the finish. i know is here is a small traffic island which is factored in which 6 or the water flows along it and then reaches a local low point on. so now look on teeth. this is the vest bonham station an underpass 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 via their feel. 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 . however, 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're gonna say if a hospital is affected or a private home where exactly and with the water will be taken by your supervisor, we will not have it just needs to be formulated in simple terms of penetration. so no meteorological jargon, robbery terms. everyone can understand that,

and he says on investment, for example, 50 leaders per square meter, littleton, colorado, in or on the 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 of him and his little soon forgotten. they could refer to the map in the forecast log 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. emergency now normally is oil and gas made the relatively small european country veggies rich la regents on more money compared to other europeans. the capital city also is a small city. about 700000 people live ship. most of them like all slow because the

e killer to this isn't just about new technologies. what it's about a new way of thinking that we need here, and greece, 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, pasta, you rides his bike where he can. 3 colors become known as the countries bicycle, friendliest town. the otherwise of age, community of over $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 step 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 say young creative start up, settle here. usually with the right thinking we can stop to migration to the big cities. and when the young people back to push, like his women, george's crystal moto says in the vanguard of the young tech elite,
