the glistening place of long, the mediterranean it's waters connect people of many cultures. seen of almost rock enter far dual career drift along with exploring modern lifestyles and mediterranean where has history left its traces leading people hearing their dreams ready to meet this week on d. w. with water is a basic need for all living beings without resources,

out on the threat side to say fresh water supplies from the tibetan plateau will decline. it, give us the belief by 2060. what can we do today to mitigate them? domino effect of such a collapse in central and south asia, water supply systems. that's what we talk about today. hello, welcome to eco india. i'm some of that i let start in bangalore who in india, salt over the last decade the city has worked aggressively to build systems for treat all the sewage it generates falling. 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,

lew 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 raised water. a novel approach that export sake and curve water pollution and save fresh water traditionally. so which 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 this ever growing demand for sewage treatment. in 2016, they introduced a mandate requiring people to treat their own sewage in decentralized sewage treatment plans located and apartments apartments in complexes like the one as each 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 have a issue lay guard. we were our water source was warwell and are well known, widely level depleted shortly and our view started buying more powerful monster. that's no longer necessity thanks to the complex on sites who which treat planned. but many been the lu residents 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 b operator working in 3 different shapes and forms in the morning. thing is the, the, every day to times he used to want to and i want to be water quality and melissa level, in addition to the operating costs and the labor required to run them. such plants 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 planned that is cheaper any easier to operate. when a start to finish and how do you feed the theme? is me said look, i need to how did need to form from richmond. and it's in the most because i was looking at ms. smith or adding back to the number one of a is not sustainable. so how do i need to solve for the phone and other big bacteria? one from one organic, some with less, not a big on the water, send them back to the phone, separate on board and executive. and that's also present thing to some extent. and also the 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 our digestive system this 90. busy 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 stuart of the underground residential buildings have more room for communal 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 sufficient central command that roger lived in an enclave. that recently switched to this model. he's happy with the result of quality of peter rod. if you see that and it looks constantly or so during the final out when you get to clear water and we let this water photo regarding the grown water, the same met dixie as after the city mandated by which, which treatment recycle water still only account for 10 percent of the lose daily water consumption, more than half of the water treated on private premises, that means unused, and is funneled into leaks in and around, bang

a little. this water is written new trains that are good for gardening, but harmful to lake ecosystems. here they contribute to toxic fun. 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 effluent, but it can also help with the water gas, the problem, the city as a whole because it's a bring down the water that's needed for things like construction, industrial 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 to quiet planning not a whole full outlook for other cities across india. that fees are fast approaching what prices where innovations in least what management could make a clear difference. but the 8th from bang, the noodle,

the self contained community of auto will not, is aiming to set the standards for the net energy positive habitat. it's cool housing. project humans keeps isn't think we need to. the community, for example, collect rain water in a unique manner. let's see how have you ever stopped and notice how was it is that a buildings and there are roads. this is contractor local and he is famous for building green building, our liberal quality greenhouse of buildings. our president would plan to increase, but we don't feel that we're, since we've been doing only data. sustainability is very simple. just think twice the kindly part, every hour we really need this. it can be even for a pain which you buy or the square foot of building. you build me as an architect. she and her being worked and as well as me, an architect and all been plan of the building o'bonham station project in order will put cheating. they called it humans keeps and with humans,

gifts they had one goal. if we can build differently with different kinds of technology and planning, and actually of young people live in it, you actually influence a generation that is more human scapes as about how to make changes for building more sustainable india. so you want to build a sustainable building. what do you do? the 1st thing is never most of the lands 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 carved the landscape. and when you disturb it, what happens is what happens in china every month on water boards and standards on people's houses and other people don't even have drinking water. so the best way to avoid this kind of open flooding, oven drugs is to manage a water. most of the water that falls on our head is what we should work with.

so either when they're putting out rainwater hot, this is early in water harvesting tank. we have channels in water from the roof in different areas below. dan connected to chains stains. we can see that gene systemic all tradition houses. the rainwater goes on to these chains and it flows without spillage. if he 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 gl or m over there in the main area. brakes have been clean in between the cement blocks for the rainwater to penetrate and flow. in the center, we have a board available even if there is accessory in for the water will drain slowly. this is how we harvest green water here, so you put it on the rainwater owner. harvest one. 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. capes, 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. another agent, this directly increases once 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 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? it burned the bill in this building. the walls are 24 centimeters thick 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 wall, 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 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 accounting 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 reinforced concrete anika versus the gulf. so if this is formed as breaks at age 2, between 2 beam strong in normal fire breaks, there is no steel, cement, or plaster needed, or plastering needed apart from reducing steel interment. very cycle, 3 important details in the building industry. steadwood of other ways ended up in london's 1st construction, which was crushed and used in the modern world. then to cut don't keep, they use discarded. 3rd quality weights 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. but 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 post 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 was very comfortable for me here. i moved here in february and 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 enjoyed that sharing a lot on the shutting. you didn't go, nobody called me go and can people to share in the useless office or utility block with an area set aside for waste. vacation and common washing machines is included normally, tonya. and instead of buying a washing machine and spending more on electricity, water, we have common ones here. i don't come when i will go to bed and then i'm done. you in the baseball, most of us you 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 entered on mystic scale is the rooftop solar panels combined with an efficient building design. so how can we say 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's interesting and not addressing a low income group, housing it we will try for $45.00 kilowatts with about 30 percent less and more the standards and we're chipping. it can someone replicate from the mother? sure it can be done, but it can be copied as such. design books are only in this context. we have read or appeared to be of use,

the older 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 human scapes 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 left to it. this isn't the only solution, but it's definitely much needed stock. ah, the fruits, vegetables and greens, we require 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 has minimize the let's see how anyone who has driven through the state of punjab is familiar with this sect feels of body the rice

chrome. historically, rice has been grown here just like this. the method is called puddling, 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 on not having to figure out ways around it. like good breed thing. who was experimenting with a technique that is making inroads in north india? bonnie vacuum gayona's already every year the water level is falling by 5 to 10 feet or up to 3. me does, in our landlord only be adopted the died at sewing of rise technique good because it requires less water level of thought. again, you started to understand how the direct sewing technique works. so 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 in 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 as been jobs, water tables shrinks. it is predicted at 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 yields remain 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 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 model for the ration dr. gur, they've seen kush as an independent agronomist from the region who says that d s r is the way forward. this is very on board to inter. i totally know another country is you know they, they also do the dsr. oh, was fluid your job or it won't unite your spheres. so you see an order? not any big convention. it's dead. 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 conditions 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 shambles belongs to the majority of small farmers who have not switched over yet. tv. okay, you convince me to adopt dsl. i agree that it will save water badly about anybody, but my father and grandfather has 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 1st who do i do actually do is growing rather since voted in boerger. so my personal lenders in years or so?

no, sir, really, robert, prince switch do not actually 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 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 want a 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. then 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 jo ann, the glacial lakes have become a major flood threat. nearly 20 mountain lakes are currently at rest. in the south,

every time 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 returns, population has no access to clean drinking water. we had out to see the source of the villages water supply some 16 kilometers away. village leader. none that al carol wants to show an environmental expert. the situations are facing her world with less frequent disputes with the neighboring villages. the rules for access to spring water, a strict nam gay who works, but returns tarianna foundation hopes to improve water management head. 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 take. they also, they also have $400.00 households and a population of $4.00 to $5000.00. what 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 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 your coach. and because of that only give to all sorts of skin diseases and 31 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 dawn. and then all like alone, floated williams fernando and destroying the waterfall. fibro did you want to go? a preliminary report to him. i'm here, the village belt a water tank to irrigate that fields. the water comes from the mountains 3 plastic pipes, but they are often damaged and landslides. and then as the elephants it was 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 water. we try to scare them off with noise enter flashlights,

utopia gillum. and the electric fence is being held to keep the elephants out. that way the hurts will stay in their natural habitat where they have an important role to play. with 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 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 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 the 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 is it okay to simply make music in times ah, an encounter with ukrainian store conductor, sonali, ne, celebrated by audiences in by voice. son, albany,

on balancing part and who aren't 21 in 30 minutes on d. w. small acts can inspire big changes, meet the people making a possible go africa joined them as they set out to save the environment. learn from one another and work together for a better future. ah, many thoughts to you all for choosing it to africa. on d w. oh, hello guys. this is the 77 percent. the platform for africa. you to defeat issues and share ideas. you know, on this channel we are not afraid to dedicate young people clearly have the

solution. that future belongs to the 77 percent. every weekend on d w in mind, when you were an architect local on land or not at all, women in architecture. why are they so invisible to the larger publisher? we decided to ask them and help women go up with the inefficient home model. if they can't identify with certain professions about their guiding principles basis. and what is the poetry, the secret of the houses and i'm homes about their motivations. architecture does so much to you, it means you the goal of architecture is to create happy dad for human about their struggles and dreams cannot sponsibility of human to they have so much

to lose shattering the glass ceiling women in architecture. this was, this has to be really, really good. start september 30th on d, w. ah, ah, this is the w news coming to live from berlin. plans for a referendum in russian held castle are put on hold. pro moscow officials had been discussing a boat on the region, joining russia, but ukraine's counter offensive means their plans are quote on pause.
