ah water is a basic need for all living beings, but that resources are under threat. signed to save fresh water supplies from the tibetan plateau will decline in the most the belief by 2060. what can we do today to mitigate the domino effect of such a po labs in central and south asia, local supply systems. that's what we talk about and it hello, welcome to eco india. i'm some of that i call let's start in bangalore, in india, south, over the last decade, the city has worked aggressively to build systems to treat all the fluids in generate following a government directive. larger apartment complexes now have to set up food

treatment plans to treat and dreams, their waste water. the visitor to such plans to find out if this approach is easing bengals water was the ah, a deep body 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 seek and water pollution and save 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 which treatments in 2016 the introduce a mandate requiring people to treat their own sewage in decentralized. so shape and

plans located in apartments. apartments in complexes like the one a g binding calls whom it installed a convention sewage treatment plant to comply with the rules. it's one of more than 2 and a half pounds in small scale sanitation systems now operating in banga. lulu. collectively this d centralized network treats about 20 percent of the cities c bridge. households use this recycle water to flush toilets and water gardens. in 2013, we had a lake, we were our water source was warwell and don't want to depleted totally. and we started buying water for that's no longer necessity times to the complex on sites which treat plant. but many bengal 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 or only

the be operator working in 3 different shapes and quantum monitoring his data every day. 2 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 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 planned that is cheaper any easier to operate. when a start to finish and how do you feed the image? we said, look at nature, how good news you're far from. the reason 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 did need to solve? so the phone and of the big back to the is the one from one organic, some with less, not a big on the water. send me back to the phone, separate under what and to make you aware that 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 to be mimicking account digestive system. this 90. busy seavent with bacteria in underground chambers. gravity moves the sea ridge from chamber to chamber. the far that it goes, the more the solid will settle down and the water gets cleared out 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 lac 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 quality of peter rod. if you see that and it looks constantly or so during the final, how would you get to clear water?

and we'd like 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 bangles. daily water consumption, more than half of the water treated on private premises, remains 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 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 effluent, but it can also help with the waters guess 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 aquifers charge if it's

done well. so the possibility these are endless, but it just need to quiet planning not so 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 east 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 causing project. human scapes 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 a devil of a buildings and there are roads. this is contractor local, and he is famous for building green building, or the people call it

a green house of buildings or president with branch 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 on as well as me, an architect, an open planet, to build an open habit asian 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 goes and stands on people's houses and other people don't even 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 now 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 village. 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 gl or m over there in the main area, brakes have been placed 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 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 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 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 dependents 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 and the buildings faced the static shade 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. 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 $4.00 to $5.00 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 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, you're barely scratching the surface of sustainability while constructing buildings and cities. we need to remember that the building industry is one of the major

contributors of energy in this world. in 2020 this sector accounted 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 you to . 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 on the cubs versus the gulf. so if this is formed as breaks at age to between 2 beams, in normal fire breaks, there is no steel remainder plaster needed or plastering needed, apart from the reducing steel interment. very cycle 3 important these materials in the building industry. steadwood of other ways ended up in london's 1st construction, which was crushed and used in the other 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 implement with design, so forced occupancy. how do you actually include the 15 of the 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 comfortable room but i'm a company, it's very comfortable for me here. i moved here in february. i haven't felt lonely since then because there are enough people to talk to here on days. i haven't

prepared dinner and they make dinner for me too. but i enjoy that sharing a lot and shutting it in a level because going great people sharing the useless office or utility block with an area set aside. pervasive vacation and common washing machines is included. but normally tiny, instead of buying a washing machine and spreading more on electricity, water, we have a common months here. come when i will go to bed and then on the new on the spot, most of us, he won't waste water. gene is what it is. the cycle and reuse for the garden. i didn't, i'm on the blind. when did you wonder? 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 almost a scale is the rooftop solar panels combined with an efficient building design. so how can you say it's making a significant difference in electricity consumption among the residents? what is actually the average energy consumed per person for emergency housing, which is middle income group housing that's interesting and not addressing

a low income group. closing it. we will try for $45.00 kilowatts with about 30 percent less than more the standard and we are chipping it. can someone replicate some? i'm not sure it can be done, but it can be copied as design works out only in this context. we have read or appeared to be of use, the order technology, what materials are available locally? how does that reflect in that climate? we have got to consider all this to you. so that's me. and for being told that this model of human scapes will 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 really into climate change, but all to contribute, let's do it. this isn't the only solution, but it's definitely much needed start. 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 create. a special technique has minimize the let's see how any one who has driven through the state of bond job is familiar with this sect feels of paddy the rice chrome. 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 bun, job is now facing and increasingly severe water crisis. farmers and having to figure out ways around it like go policing. who was experimenting with a technique that is making inroads in not india bonnie ducking. okay. almost

every year the water level of falling by 5 to 10 feet of a lot up to 3 me does in our landlord only be adopted the dido, sewing of rise technique, good because it requires less water level. so to get you started to understand how the direct sewing technique works. no, we're going 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 me 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 also save labor and related costs, an advantage in punjab, whether is a labor shortage. on india, democracy, quit vieza. i have saved almost 20 percent of my water bill and you can see her here. this has not affected the quality of my paddy at all. i don't. how can i go? 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 the d s r is of the way forward. this is very important. i totally

know another country is, you know, they also do the dsr. oh, was fluid your job? oh, i swamped united spears, so you soon order. not any big and when sham it's dead. i am in houston or the bluetooth. so it shouldn't be used in north year, but they have to adapt it, adapt this to the local by local conditions. he means that i do mean obstacles him farmer than punjab. generally don't burn land large enough to justify the cost of machines on their own and paying for labor to plant rise by hand. especially during the labor shortage is costly. the 2nd reason is that the thing did a lot of lead wrong. if there is 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 the d. s. our crops need to be irrigated exactly 3 weeks after sewing to create the best results. ability, the main issues 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. our crops dry and die, she shamble belongs to the majority of small farmers who have not switched over yet . diggity ok you convince me to adopt dsr? i agree that it will save water, bentley, bonnie but they 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 1st 7 days you do actually do is ready rather to go to the board. so my personal linda is direct in years or so. no, so every farmer prince, switch the audio. 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 done is started 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 of be tom glaciers, the mountains are sacred. like these 7000 meter peaks at the border to the back. then the glaciers days appear to be numbered. the ice is melting. g to climate change are shown on this animation by the w w. f and the you, the glacial lakes has 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 seed sown 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, more 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 are carol wants to show an environmental expert, the situation that are facing her world left and frequent disputes with the neighboring villages. the rules for access to spring water, a strict nam gay who are expert returns tarianna foundation, helps 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. also. they also have 400 households and a population of 4 to 5000 already like so they're dipping into this water. they already been in this, 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. they don't have enough water to wash her 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 pel. 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 reinforced for all the further coming gone and all like alone. float all you do with him before window and destroying dogs. waterfall fibro, did you want to do that? or probably more than the route laundry from the village bell to water tank. to

irrigate that fields, the water comes from the mountains, 3 plastic pipes that are often damaged and landslides. and then as the elephants don't know 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 whatever we try to scare them off with noise, enter flash lights with 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. i'm really good movie. look 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 done it. he or bunch of pulled the regeneration off or it 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 residence of the mountainous kingdom, half little of a choice. some scientists predict now the walls of the future will be fought over water. many in our generation already living with the inaccessibility to portable water. the smallest individual action could help to fix that leaky tap done 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

ah, ah, with in good shape. don't be afraid for some. ready that's easier said than done fear to drive our thoughts and behaviors.

so the question is, what are the effects of fear and how do we overcome it in good shape next on d w. yeah, there's an old saying, show me how you live and i'll tell you when you are a visiting king luke fish, the 2nd varia, f noise schwann. shine. castle were given an exclusive tour by his great, great grand nephew. and get to see what remains hidden. to most your romance. a 60 minute d, w. ah ha, we're all set to go beyond the obvious. and

as we take on the world 8 our, i do all the fans. we're all about the stories that matter to you. whatever it takes, 5 policemen, a pain you don't know, we are your is actually on fire. made for mines with lack of social contact, fear of becoming infected, financial worries or grief of the deceased loved ones. more than 2 years of the coven 19 pandemic have had a tremendous impact on the mental health of people worldwide. according to the world health organization, anxiety and depression increased by.
