ah, d w i, she's gotten used to thought so crazy. with water is a basic need for only being big. but our resources are under threat. trying to save fresh water supplies from the tibetan platter will decline if you must believe by 2060. what can we do today to mitigate domino effect of such

a problem in central and south asia, water supply system. that's what we talk about today. hello, welcome to eco india. i'm some of that i let's start in bangalore, in india, salt, over the last decade, the city has worked aggressively to build systems to treat all the fluids generate following a government directive. larger apartment complexes now have to set up food treatment plans to treat and reuse their waste water. the visitor to such plans to find out if this approach is easing bengals water was the ah, a jeep bonnie good overseas. the sewage treatment plant at his apartment complex. the software engineer lives in banga, lew india, the fastest growing city that struggling to meet its water needs. its the country's 1st to port residence in charge of their raised water. a novel approach that

explored seeking water pollution and safe, fresh water traditionally. so achievement happens in centralized treatment plans. but what daniel has done because the city has sort of leapfrogged in its development. the utilities haven't been able to keep pace with his ever growing demand for so which treatment in 2016, they introduce a mandate requiring people to treat their own sewage in decentralized. so she's been plans located in apartments. apartments in complexes like the one i g, monica calls whom 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 bengal, lou. collectively this d centralized network treats about 20 percent of the cities c. ridge households use this recycle water to flush toilets and water gardens. in 2013, we had a lake, we were our water source was well and going to another depleted totally.

and we started buying water for months or not, no longer necessity times to the complex on site to which treat plant. but many bengal lew residence, complain about the high acquisition and running costs. we are selling order on the $60000.00 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 is the, the, every day to times he used to want to and i want it to be water quality and melissa level, in addition to the operating costs and the leader to address these issues with a small scale treatment plant that is cheaper. any easier to operate when a start to finish and how do you feed the sea bass? we said let's look at nature. how did need to far from redmond nathan the most because i have this ling, i'm business or adding back to the number one is not sustainable. so how did need

to solve? so the phone and of the big back to the one from one organic on which that's not a big deal. so what is in to me back to the home, super of got and executive. and that's also going to some extent and also a phone call. stomach is a very good and it back to your mission so to speak. it can but i don't even think mimicking a cows digestive system this 90, to see it with bacteria in underground chambers. gravity moves the c ridge from chamber to chamber, the for that 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 stored 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,

but in the long run the company saves. they're far more cost efficient. central command raj and live than an enclave. that recently switched to this model. he's happy with the result of quality of the right. if you see that bless it, but it looks constantly. so during the final, when you get to clear water and we let this water photo regarding the grown water the same 6 years after the city mandated guy, which, which treatment recycle water still only accounts for 10 percent of the lose daily water consumption. more than half of the water treated on private premises remains unused, and is funneled into leaks in and around bank a little. this water is written new trains that are good for gardening, but harmful to lake ecosystems. here they contribute to toxic fung dropping 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 scares 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 possibly these are endless, but it just need acquire planning not so full outlook for other cities across india . that fees are fast approaching what to try says where innovations in least what management could make a clear difference. but the east from being the noodle, the self contained community of auto. when somebody is aiming to set the standards for the net energy for habitat. it's cool housing project. hugh once keeps isn't think we need to the community for example, collect rainwater in a unique manner. let's see how have you list open orders? how was it?

these are developing a buildings and there are roads. this is contacts a local and he's famous for building team building quality greenhouse of buildings are present with plants increase. but we don't feel that way since we've been doing only data. sustainability is very simple. just think twice the can be bought barre . oh, we really need this. it can be even photo pain. when you buy auto square for the building, you build me as an architect. she was under me an architect, an open plan, of the building, open, happy edition project in order will put gd, recorded, humans keeps. and with humans case, they had one goal. if we can build differently with different kinds of technology and planning and actually have young people live in it, you actually influenced a generation that is what human scapes of about, how to make changes for building more sustainable india. so you want

a sustainable building, what the 1st thing is never meant for the land natural landscape. when a drop of water falls 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 disturbing it. what happens is, what happens in gen i, every month from water goes and stands in some people's houses and other people don't new, i'm drinking water. so the best way to avoid this kind of open flooding, all of and drugs is to manage a water. most of the water that falls on our head is what we should wirklich. so even under but the rainwater hot, this is early in water harvesting tank. we have channels in water from the roof in different areas below then connected to change. we can see the chain system and all tradition houses. rainwater goes on to these genes 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 on the ground on the speed on the car. ah, in the main out of the gl or on border in the main area, brakes have been placed 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 invoice, the water will drain slowly. this is how we harvest green water here. so you put it on the rainwater on the card with wonder. 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 caps 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 care dentist with a lot more than those another agent, this directly increases wants dependency on fans and air conditioners. and

indirectly, the dependent on electricity to that 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 in the buildings, these, this static shade on the face, plenty of other cars. next problem is heat heat. so we look at all the sun moves, what time of the day the sun hit, which part of the building, and what do you put inside the building in those places where the sun is hitting it? when 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 through it. by the time it penetrates 4 to 5 centimeters to the world, the sun has set and so the house doesn't warm up at all. yeah. right. so it's between the sun and the wind 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 that. if you were to apply just these 2 concepts to developing urban cities, you're barely scratching the surface of sustainability. well, constructing buildings entities need to remember that the building industry is one of the major contributors of energy in the world. in 2020, this sector accountant for 36 percent of global final energy consumption. and 37 percent of all energy related carbon dioxide emissions. a huge contributor to the change is the building materials. usually we want to have building materials which a little carbon footprint. so we look at what is it that we want to avoid, or at least reduce? for instance, of the ceiling. they use the woodstock instead of depending on reinforced concrete on the card surface and the surface is formed as breaks at age between 2 beam strong. in normal fire bricks, there is no steel, cement or plaster needed or plastering needed apart from reducing steel. and i

meant very cycle, 3 important details in the building industrial subunit of otherwise ended up in landfills. first 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 ways, limestone pieces for the want. not only do these 2 material from the governors in the building, but they're also cost efficient material. but the believe the important thing is that there is no material cost in the construction as we use beast and scrap material every 2 weeks we collected traps and small quantities from local shops in the week. we repeated 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 actually influence a 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 comes from but i'm

very comfortable for me here. i moved here in february. i haven't felt lonely since then because that enough people to talk to here on days. i haven't prepared dinner and they make dinner for me to one. i enjoy that sharing a lot on the shutting. you didn't go, nobody called me go and people to share in the useless office or utility block with an area set aside for waste. vacation and common washing machines is included, but normally tiny. and instead of buying a washing machine and spending more on electricity, water, we have common ones here that com, when i go to bed on the, on the new in the base. but most of us, he won't waste water. jamie, what is the cycle and reuse for the garden? i didn't, i'm on the blind to can, did you? you can't keep talking about electricity consumption when you thinking of a sustainable building for the indian subcontinent, particularly terminal. one of the most reliable sources of renewable energy. domestic scale is the rooftop solar panels combined with an efficient building

design. so how can a phase, it's making a significant difference in electricity consumption among the residence? what is actually the average energy consumed person for emergency housing, which is middle income group housing that's interesting and not addressing a low income group, housing it we will try for $45.00 kilowatts about 30 percent less and more the standards and we are chipping. 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 the order of technology. what materials are available locally? how does it reflect in that climate we have got to consider all this other you know, 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 a lead 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 required a lot of water to be grown. 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 k g of drain. a special technique helps minimize this. let's see how any one who has driven through the state of punjab is familiar with this sect feels of paddy the rice cropped. 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 been job is now facing and

increasingly severe water crisis. farmers and having to figure out ways around it. like go breathing who was experimenting with a technique that is making inroads in north india. bonnie are gonna be on a via the water level of falling by 5 to 10 feet of up to 3 meters in our line. arguable only be adopted, the died at sewing of rice technique will because it requires less water level of thought. again, you started to understand how in the direct sewing technique works, though we've got to look at the older 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 me not groovy on a few decades. direct sewing or the dsr technique is the alternative where seeds are soon directly by hand or machines. more seeds may be needed for the same area, but yield remains largely on par with the traditional method. machines also save labor and related costs. an advantage in punjab weather is a labor shortage. quantity to our democracy with deicide i have saved almost 20 percent of my water and you can see here 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 version. dr. gor, they've seen kush as an independent agronomist from the region who says that dsr is of the way forward. this is very important to her. i totally know another country is, you know, did they also do the dsr? oh was, did your job, why swanky night to spears? so you soon order not any big and when sham, it's dear. i mean there's used in other places. so it should be used in north india, but they have to adapt it, adapt this to the local issue 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 lead. 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 technology. the main issue is that i need to pump the water at a particular time and what we're doing with the electricity supply feels like it often does. i crops dry and i shift shamble belongs to the majority of small

farmers who have not switched over yet. digger d. okay, you convince me to adopt dsr? i agree that it will save water, bentley about anybody but my father and grandfather had 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 we decides, and electricity issues before there can be a large scale adoption. the 1st who do i do actually do is growing rather since voted in boerger. so my personal lenders, in years or so most every wardrobe prince switch daughter. so the 1st steps have already been taken and supporting farmers and making the switch with take the state and of goals of water conservation. a long way would done is touted on 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 are they tackling this? let's find out. for the people of be 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, the jo ann, the glacial lakes have become a major flood threat. nearly 20 mountain lakes are currently at rest. in the south of britain, 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. it springs, running dry and mountain streams have slowed to a trickle according to the un or than 60 percent of returns, population has no access to clean drinking water. we had out to see the source of the villages hall to supply some 16 kilometers away village liter. none that our corral wants to show an environmental expert, the situation they're facing here with less frequent disputes with the neighboring villages. the rules for access to spring water, a strict nam gay who works, but returns tarianna foundational hopes to improve water management. her the project receives support from the international climate initiative is what this water belongs to. another group we've already spoken many years ago that we can share the water for cultivation. everything. but she wrung tell you also they also have $400.00 households and a population of $4.00 to $5000.00, or do they like?

so they're dipping into this water, dealt with at least they share the drinking water with us, but it's not a solution with the drinking, but the young students who attend setting tay 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 coach. and because of that, when you get all sorts of skin diseases and 31 very big challenge, the narrow valley in the south of baton 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 down and all like alone, float williams fernando and destroying the waterhole. 3 fibro. do you want to do that or to live in the regal on different? i'm here, the village belt a water tank to irrigate that feels the water comes from the mountains 3 plastic pipes, but they're often damaged and landslides. and then as the elephant didn'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 what we try to scare them off with noise. enter flash lights, utopia and electric fence as being dealt to keep the elephant south. that way the hats will stay in their natural habitat where they have an important role to play with. i'm really good movie. but the elephant is an architect of to for us. he decides what the forest is going to look like. and if there is a tick pushes,

ah, he just go in with 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 have 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 fix that leaky tap. turn off the running water while brushing your teeth. have shorter showers. i leave you with that and see you again next week. good bye. and thanks for watching.

with blue. ah, with

ah! with oh neighbors. more enemies on the russian border lies the finished village of their center, where the residents are deeply divided. some of them want nothing to do with their russian neighbors, while others see them as human beings, not warmongers. focus on europe. in 30 minutes, w into the conflict zone with sebastian russia.

jewish community has been watching the war in ukraine with mounting alarm. but most of the island fearing state reprisals, the senior figure in the community help but silence was the moral. the think us go to read and he wants all jews in russia to get out. now the conflict zone in 90 minutes on d. w. o. m. i, when you were an architect all in or not at all. women in architecture. why are they so invisible to the larger publisher? we decided to ask them. and for women go up with an inefficient model. if they can't identify with certain professions about their guiding principles. messes and

what is the poetry the secret of a house? and i'm hollins about their motivations. i can fax you guys so much to you. it needs you. the goal of architecture is to create habitat for human, about their struggles and dreams, sponsibility of humor. they have so much to lose shattering the glass ceiling women in architecture. does this have to be really, really good? start september 30th on d, w. ah

ah ah, this is dave. any news live from berlin? i renewed commitment to helping you crime in the long term. we will work together to train your crimes for fish. for the long haul, we work together to help get a great ukraine's capability and bolster its joint operations. for the long haul west and allies made in germany.
