waterfalls flowing water particles into the air b, trees, sweating out up to 1000 liters of water in a day. or sea forest fires, evaporating large amounts of moisture tune in to get the answer. learn more about this phenomenon, a heavy, invisible river that flows through the sky starts march 23rd on dw. ah, with water is a basic need for all living bigs. but our resources are under threat. signed to save fresh water supplies from the tibetan plateau will decline if you also believe

by 2060. what can we do today to mitigate the domino effect of such a pro labs in central and south asia, water supply systems. that's what we talk about today. hello and welcome to eco india. i'm some of that i let start in bangalore in india, salt over the last decade. the city has worked aggressively to build systems for treat all the sewage it generates following a government directive. larger apartment complexes now have to set up sewage treatment plans to treat and reuse their waste water. we visited 2 such plans to find out if this approach is easing bengals water was not a g. bonnie good overseas. the sewage treatment plant at his apartment complex. the software engineer lives in banga, lulu india's fastest growing city that struggling to meet its water needs. it's the

country's 1st to put residents in charge of their reast water. a novel approach that explored seek and curve water pollution and save fresh water traditionally. so each treatment happens in centralized treatment plans, but what bang law has done because the city has thought of leap frog in its development. the utilities haven't been able to keep pace with his ever growing demand for sewage treatment. in 2016, they introduced a mandate requiring people to treat their own sewage in decentralized. so achievement plans located and apartments. apartments in complexes like the one a g t panica calls home. it installed a conventional sewage treatment plant to comply with the rules. it's one of more than 2 and a half 1000 small scale sanitation systems now operating in banga. lulu. collectively this d centralized network treats about 20 percent of the cities see which households use the 3 cycle water to flush toilets and water gardens. in 2013,

we other issue lay guard. we were our water source was warwell and are no longer level depleted shortly. and our view started buying more powerful monster. that's no longer necessity, thanks to the complex on site to which st and planned. but many been the lou residents complain about the high acquisition and running costs. we are selling order on the 60000 of this settlement for the average. and also end of the year. every year we need to order only the be open to working in 3 different shapes and quantum, monitoring it every day, 2 times a used to one. and then i want it to be water quality. and emily level, in addition to the operating costs and the labor required to run them, such plans also take up lots of space. who are maintenance can lead to unpleasant orders? an disturbing noise, a local start up sought to address these issues with

a small scale treatment plant that is cheaper, any easier to operate when they start to finish and how do you feed this is lisa, look at nature. how did need to far from richmond, and it's in the most because what happens when our business or adding back to the number one of a is not sustainable. so how did need to solve for the phone and of the big bacteria? one, phone, one, organism. it's less not a big on the water, send them back to the phone super time. you've got an executive where you're going to phonics and, and also the phone call. stomach is a very good and i think back to your mission so to speak. it can, but i don't want to be mimicking a cows digestive system. this plan treats seavent with bacteria in underground chambers. gravity moves the sea ridge from chamber to chamber. the farther it goes, the more the solid will settle down and the water gets cleared up until it is finally safe to use for non portable purposes. ah,

with the plan stuart of the underground residential buildings have more room for community spaces, like playgrounds, at $22.00 lack rupees or $27000.00 euros. these plans are somewhat more expensive to install it. but in the long run, the company sees they're far more efficient center, martin that raj and lived in an enclave. that recently switched to this model. he's happy with the result, the quality of the people, right. if you see that and it looks constantly or so during the final, how would you get to clear water? and we lay this water for regarding the grown water the same but 6 years after the city mandated guy, which, which treatment recycle water still only accounts for 10 percent of bangles. daily water consumption, more than half of the water treated on private premises, remains unused. and is funneled into leaks in and around. bungalow to this water is written new trains that are good for gardening,

but harmful to lake ecosystems. here they contribute to toxic fun frothing on the water surface. we find ourselves at a very interesting point in the sewage treatment starting because if the government actually find alternate uses for this water, it will not only incentivize residents to maintain their systems better and have better quality fluids. but it can also help with the water scarce the problem, the city as a whole, because it's a bring down the water that's needed for things like construction industry greening box. and as well as even thinking about aquifer the charge if it's done well. so the possible and these are endless, but it just johnny requires planning. that's a whole full outlook for other cities across india. that fees are fast approaching what prices where innovations in least water management could make a clear difference. but the 8th from being the noodle, the self contained community of auto. when somebody not is aiming to set the

standards for the net energy, positive habitat, it's causing project. human scapes isn't think we need to. the community, for example, collect rainwater in a unique manner. let's see, how have you ever stopped and this whole is, it is a develop the building and there are roads. this is contacts a local and he's famous for building green buildings. have other people call it a greenhouse of buildings are present with plants increase, but we don't feel that reasons we've been doing only data. sustainability is very simple, just think twice the can be bought very. i'll be really need this. it can be even photo been when you buy auto square for the building, you build them as an architect, she would be done. this was me, an architect, an open plan, of the building, open, happy patient project in order will put cheating, recorded humans cubes. and with humans case, they had one goal. if they can build differently with different kinds of technology

and planning, and action of young people live in it, you actually influence a generation that is what human scapes is about. how to make changes for building more sustainable india. so you want a sustainable building. what do you do? the 1st thing has never met the natural landscape when a drop of waterfall here, where does it go and where does it end up? you know, this is over a long geological period that water has caused the landscape and money disturbed it . what happens is, what happens in gen, every month to water goes and stands on people's houses and other people don't even have drinking water. so the best way to avoid this kind of flooding out of drugs is to manage water. most of the water that falls on our hand is what we should work like. so either under putting not rainwater hot,

this is irene water harvesting tank. we have channels in water from the roof in different areas below, dance connected to chains, chains as we can see, the chain systemic old tradition houses, the rainwater goes on to these chains and it flows without spillage. if we allow the water to hit the ground with the same force, it leads to high soil erosion. so we reduce the speed by laying bevels on the ground and the speed on the couch. mm hm. in the main or at the gallery border in the main area, brakes have been clean in between the cement blocks for the rain water to penetrate and flow. in the center, we have a board available. even if there is accessory in fall, the water will drain slowly. this is how we harvest green water. here are you pretty low and the rainwater owner hardware. wonderful. now that you understand how to build according to the topography you need to focus on the climate zone you're

going to build in humans. kids for example, is built in a hot humans on. but the main problem is heat and humidity. when these 2 come together, a person living here tends to switch a lot more than those and other regions. this directly increases ones dependency on fans and air conditioners. and indirectly, the dependent on electricity to red eustace, the architects focused on crossway installation in each house. so on the breeze, then we check for the direction of the breeze. it's in the north south direction. that's by all the openings and the buildings faced the static shade of on the face . plenty of other car. next problem is heat heat. so we look at all the sun moves, what time of the day the sun hits, which part of the building, and what do you put inside the building in those places where the sun is hitting, we bring the bill in this building. the walls are 24 centimeters. take them and are built with natural red soil. yeah. the clear type wall doesn't allow the heat to penetrate. by the time it been address 4 to 5 centimeters with the walls,

the sun has set. and so the house doesn't warm up at all between the sun and the when and the angle of the building, you're actually work out how to put various functions inside the building. and then you have comfort. it's as simple as if you were to apply just these 2 concepts to developing of in cities, your values scratching the surface of sustainability while constructing buildings in cities. we need to remember that the building industry is one of the major contributors of energy in this world. in 2020, this sector accountant for 36 percent of global final energy consumption and 37 percent of all energy related carbon dioxide emission. a huge contributor to the change is the building materials. usually we want to have building materials which have a little carbon footprint. so we look at what does it that we want to avoid, or at least reduce. for instance,

of the ceiling. they use the woodstock instead of depending on the reinforced concrete on the card faces and the surface is formed as breaks at age between 2 beam strong in normal fired bricks. there is no steel, cement, or plaster needed, or plastering, need it. apart from the reducing steel, implement the recycle 3 important base material in the building industry that would have otherwise ended up in line since 1st construction, which was crushed and used in the modern world. then to cut, don't keep, they use discarded thought quality rights that make does for the rules and baselines. don't pieces for the world. not only do these 2 materials and governing the building, but they're also cost efficient material for the belinda. the important thing is that there is no material cost in the construction as we use in scrap material. every 2 weeks we collected traps and small quantities from local shops in the week . we did this process as these materials are not found that easily. there's only so much that you can influence with design, so forced occupancy. how do you healing closer, sustainable lifestyle?

so that's what we'll aim that we said we aim at a huge housing program that single couples and even small families to live together in a way that the share and what the share, the share space. i think it was very comfortable for me here. i moved here in february and i haven't felt lonely since then because they're enough people to talk to here on days. i haven't prepared dinner and they make dinner for me too. but i enjoyed that sharing a lot and shutting it in a good level. he called me go and people to sharon produces a utility block with an area set aside for re certification and common washing machines is included. but normally tanya now instead of buying a washing machine and spending more on electricity water, we have common months here. i don't come when i will go to bed on the, on the new interface, but most of us he won't waste water. jamie, what is the cycle and reuse for the garden?

i didn't plan to can, did you, you can't keep talking about electricity consumption when you thinking of a sustainable building for the indian subcontinent, particularly to me. and one of the most reliable sources of renewable energy. domestic scale is rooftop solar panels combined with an efficient building design. so how can the phase it's making a significant difference in electricity consumption among the residents? what is actually the average energy consumed person for emergency housing, which is middle income group, housing that is addressing them not addressing a low income group out. with that we will try for $45.00 kilowatt, spoke with about 30 percent less and more the standards. and we are changing it. can someone replicate from another place? sure, it can be done, but it can be copied as design works out only in this context. we have read or appear to be of use for the technology. what materials are available locally?

how does it reflect in that climate we have got to consider all this and so that's me. and for being that this model of humans, gifts with a focus on co sharing could be adopted by college campuses in the future. and that's just the beginning. sustainable buildings could help develop cities that aren't just as any to climate change, but also contribute less to it. this isn't the only solution, but it's definitely much needed stuck with the fruits, vegetables, and greens. we eat require a lot of water to we grew well in 2021, 22. india was the 2nd largest consumer of rice in the world just behind china. it takes nearly 5000 liters of water to produce one kids. you drink. a special technique helps minimize this. let's see how. or anyone who has driven through the state of one job is familiar with this field of body. the rice crop.

historically rice has been grown here just like this. the method is called paddling where crops are submerged in water for weeks. this is one of the most water intensive ways to cultivate body and the results are in punjab is now facing and increasingly severe water crisis. farmers and having to figure out ways around it like go pretty thing who was experimenting with a technique that is making inroads and not india. bonnie vacuum gayona's already every year the water level is falling by 5 to 10 feet of up to 3 meters in our landlord only be adopted the died at sewing of rice. dick need good because it requires less water level of thought. again, you started to understand how the direct sewing technique works. now we've got to look at the old method 1st. traditionally, saplings of rice are grown in a nursery for weeks and transplanted into the field which are flooded. but rice is

not actually an aquatic crop. it just has a great ability to tolerate being submerged. the what is mean role is to repel pests and works as a natural we decide. in an on 5 month, the crops can be harvested and done into rice in the form. we know. but this method uses up to 5000 liters of water per kilogram of rice and has been jobs. water tables shrinks, it is predicted that rice may not groovy on a few decades. direct sewing or the dsr technique is the alternative where seeds are so indirectly by hand or machines. more seeds may be needed for the same area, but yields remain largely on par with the traditional method. machine to save labor unrelated cost, an advantage in punjab, whether is a labor shortage quantity to our democracy with deicide, i have saved almost 20 percent of my water and you can see her here. this has not

affected the quality of my paddy at all. i do not get i got the punjab state government is now offering farmers compensation for bees 1500 around 18 euros a season to switch to the new method to conserve water landscape. mrs. fears is the mother of her in the restroom. dr. gur, they've seen kush as an independent agronomist from the region who says that dsr is of the way forward. this is very on board to inter, i totally know in other countries, you know, did they also do the dsr? oh, was fluid your job or it won't unite to spears. so you say in order not any big and when shim it's dead. i mean there's used in other places. so it shouldn't be used in north to near. but they have to adapt it or not

dis, to the local condition. by local conditions, he means that i do mean obstacles him farmer than punjab. generally don't own land large enough to justify the cost of machines on their own and paying for labor to plant rice by hand, especially during the labor shortage is costly. the 2nd reason is that it did a lot of need. if there's no water weeds compete with plants and best attack freshly. so in seeds, this incidentally is why more seeds are needed for the same yield. controlling weeds and pests also requires more labor and we decides and pesticides. these can be expensive and also bad for the soil in the long run. it's a tough choice between saving water and protecting soil. but there are other reasons. testing has shown that d s. our crops need to be irrigated exactly 3 weeks after sewing to create the best results employee. the main issue is that i need to

pump the water at a particular time. and what do i do with electricity supply feels like it often does. i cropped dry and i she shamble belongs to the majority of small farmers who have not switched over yet. giga g, okay, you convince me to adopt dsl. i agree that it will save water badly about anybody, but my father and grandfather have been practicing badly every day. how can i let go of our traditional practice? the state needs to find a way to conserve water, but equally the concerns of farmers need to be addressed from the affordability of machines to the right li decides, and electricity issues before. there can be a large scale adoption the from 1st it does in the direction you do is growing rather since volleyball game. so my personal feeling is good so, so no, so really, robert prince switch to your so the 1st steps have already been taken and

supporting farmers and making the switch will take the state and of goals of water conservation. a long way who done is touted for its gross national happiness and its positive carbon balance sheet. but this hasn't shielded it from the drastic effects of climate change. the country is struggling with a water crisis. it's residents oscillate between having too much water or too little water. how would a tackling this, let's find out for the people happy tom glaciers, the mountains are sacred. like these 7000 meter peaks at the border to the back of the glaciers days appeared to be numbered. the ice is melting. g to climate change, as shown on this animation by the w w. f and the you. the glacial lakes have become a major flood threat. nearly 20 mountain lakes are currently at rest. in the south of the town, the monsoon season is normally in july, but in recent years,

the heavy rains have come to sit on tight earlier in the month of may. the seats owned by local farmers, were washed from the fields. and the rain water vanishes almost as suddenly as it appeared. springs of running dry and mountain streams have slowed to a trickle. according to the un or than 60 percent of the towns population has no access to clean drinking water. we had out to see the source of the village as well to supply some 16 kilometers away. village leader. none that our corral wants to show an environmental expert. the situations are facing hair with. they've been frequent disputes with the neighboring villages. the rules for access to spring water, a strict nam gay, who were expert returns tarianna foundation, hopes to improve water management. her the project received support from the

international climate initiative is what this water belongs to. another group of, we've already spoken many years ago that we can share the water for cultivation everything, but she wrung to you. they also have $400.00 households and a population of $4.00 to $5000.00 or so they're dipping into this water a good in this, at least they share the drinking water with us, but it's not a solution with drinking, but the young students who attend setting tase central school are also affected by the water shortage. the 860 students have just one source of water for bathing and laundry. you don't have enough water to wash your body and that they have for water to wash their cold. and because of that only give to all sorts of skin diseases and 31 big challenge. the narrow valley in the south would return near the border to india has a sub tropical climate. at the valley's edge lies the village of dutch and pal ray

. the water supply is a problem here to the monsoon has become irregular, and when it does rain, the torrential downpours often wreak havoc when the impulse for all the further coming gone and all like alone, float little uniforms before window and destroying dogs waterfalls. 3 feed, roger, you want to rule that are properly more than the read laundry from i'm here, the village belt a water tank to irrigate that field, the water comes from the mountains 3 plastic pipes that are often damaged and landslides. and then as the elephants don't, what own way they come into the village almost every night your small groups of young elephants are usually they tear off clusters of bananas or bamboo plants. 5 minutes later they leave water. we try to scare them off with noise. enter flashlights, utopia gillum, you will get an electric fence as being dealt to keep the elephants out. that way

the hurts will stay in their natural habitat where they have an important role to play with some really good movie. but the elephant is an architect off to for us. he decides what the forest is going to look like. and if there is a tick pushes, ah, he just going to trample it, and he opens up for the regeneration of 4 returns. forests are important to the countries water supply. they also play a vital role in maintaining bio diversity and protecting the climate. tiny baton is doing its best to adapt to climate change. the residents of the mountainous kingdom, half little of a choice. some scientists predict that the wars of the future will be fought over water. many in our generation are already living with the inaccessibility to portable water. the smallest individual action could help to the fix that leaky tap
