he goes next on d w. ah, what secrets lie behind these walls? discover new adventures in 360 degrees. and explore fascinating world heritage sites. d w world heritage 360. getting out now. ah. water it will appear is nature's most removal. resource raining down on us from the sky to replenish reservoirs above and below crowd. but more and more places on our planet fi, cbs shortages to the on eco india. we look at efforts to secure supplies that

sustain life on up. hello and welcome. i'm some of that water is central to just about all our activities from drinking, cooking and cleaning to manufacturing. and of course, growing food here in india, change in agricultural practices and inefficient. what are years i'd impacting the foot? i'd gung gabby said, with supplies about half of the country's koreans what can be done to save india's food basket. we met researchers on the quest for answers with the ganges river has been a blessing for many people in india for centers, and not just for religious purposes. the river supplies water to numerous cities to dig the ganges along with its tributaries, forms the most densely populated river busy in the wood. it is also considered the

bread basket of india. the muddy soil contains many neutrons. about half of india's grain is grown along these waterways. danish gemacht, the verde belongs to one of the many farming families, is that have lived in the auto opera dish, ganges flood plains for generations. he has a do hector farm and the ponder river, a smaller tributary of the ganges near the city of con pool. once he has harvested his wheat, danish won't have grown anything on his farm for the next 3 to 4 months. in a tiffany, this oil is so hard, it needs water, but we are unable to give that much water. when we don't want them, the crops die up and we can't harvest. so when it rains but only then we are able to so, and we stayed dependent on lynn values play the printer, look at it downstream. danishes farmers among the last recipients of voters from the areas irrigation canals. previously it was a primary source of surface water. today,

sitting and neglect have left these canals in a state of despair. here though, when you don't get water from the canal day, then there are 2 bills that people have bought and installed here and there. we use those by paying rupees 150, put our facility. that's a lot of money for the farmers, which many gone to fold due to increasing population an agricultural production. the water table here has dropped noticeably because of over extraction. now water can only be found at 85 feet compared to 60 feet just 15 years ago. scientists estimate that by 2050, over a 100000000 people might phase of food crisis because of the drop in the water levels and the ganges and its tributaries. to better understand and improve what availability in critical river business professor, rajiv sinner has included the pond,

rivers and whether it's 21 square kilometer watershed. in an observation project, it's done in co operation with an international research program called the critical zone observatory. through data collection, he had a steam, won't to understand the impact of human activities on soil and water. we would like to use the modern technologies which are available at our disposal and then don slid them all into some sort of inflammation system in a, in a very simple language which can be translated. i am given to the farmers the use of drones fitted with turman and high but a spectral cameras allow the recording of the smallest tinges from rainfall and soil moisture to press a petition and ground water level. set up that initial funding from the ministry of earth sciences. the indo ganja epic sees that oh, is also collaborating with the international scientific community.

my role is teach and you did some of the assessment information to see how we could and compliment sas, my observations with the very dense sense in that work in the sees at our regional satellite data. very important for the scientists and con, pulled the and allies it and informed the farmers about the results and actions to take. one of the key methods in which we are trying to give to the farmers is that you need to decide that the irrigation water requirements are based on how much stress this while is. and at a given time, rather than in leading the every time and running the bum gundy for my service to better managed to fish his results, the farmers need this regular information. the project is in it's 70 a now and denise devalued relies on the exchange with the scientists for his

farming work. jim was, i'm go by there when they tell us about when the predictions of that it is about to rain. for example, we then don't what are the crops that webinar in advance? they also ask us for information, for example, checking with us if there are any farming related issues we are facing at any point . they also conduct site data and the big samples from both. we end up learning from them, lay the phone vulgarly, that the farmers are also taking the scientists recommendations to heart and trying to clean up the canons. that way the water can flow freely and reach the fields. the project is important for more than just the agricultural sector and the bundle region. that's because the future of india's breadbasket depends greatly on whether the water is used more sustainably here and along the entire ganges river groundwater, stress like that in the gun, gar. biesen is something that's altered,

tumbling regions in germany, the state of brandenburg, the envelopes and berlin has been hit by 3 consecutive summers of trout that's now causing unexpected road blocks for businesses in the state. watch me clicking where i sit down to put on my friends was all water and 2005. brandon. both lakes strauss lies just outside berlin, like most bodies of water. here the lake is fed by ground water for some time the lake's been shrinking. losing around 600000 cubic meters of water annually. enough to supply $4000.00 german families for a year. though drinking water comes from hair that doesn't explain the huge annual losses. the shallow end of the swimming area has almost gone. so diving instructors, struggle to practice with beginners, i don't think because the area behind is too deep for initial training chief of staff on gov itsco fee as he won't be able to run his diving school much longer.

that's because the water shrinkage also has consequences for advanced divers around 30 kilometers away in berlin is the likely it's institute of fresh water ecology at mcgaffey here. eco hydrologist. dr. yog live and off ski, does his research. monday to my at 1st, when you see this much water, you think berlin is water rich type it, but at the same time, berlin is really water poor because there's very little precipitation. deutschland we are in a region of germany with the least amount of precipitation. and as a result, berlin will have big problems with quantities in the long term thing to the left. because climate change is magnifying the problem, it's likely that less ground water recharge is taking place because water is not seeping in. it's already evaporated beforehand for it, and so if i don't city it, this is already having simple consequences for forests and box chief forrester jo

donna is on his way to the lucas a lake look rhythm district. forrester peter pollack leads him to a spot where just a few years ago, they would have got their feet wet. but this bark is a living body, one that shrinking understanding here my boots are getting wet, but it's actually 2 meters below the water level. but the lake used to have the it wasn't on which puffin either by mutual in my case, my head would be under water. but that shows you the extent of the situation on yonder stellers. when major carbon sinks like felons, dry out, they release their carbon into the atmosphere that drives climate change, putting more pressure on the lakes. but the forest is spot another problem. the huge structure near by which surely requires a lot of water. meanwhile, at berlin's muggers a lake, there's more evidence of the growing water shortage and the impact that it's having

there for him. very early in the year, the threat level for forest fires was relatively high here. we have to which again shows we don't have enough water in math. in march, there shouldn't be any risk of fires. scientists have been tracking the growing water shortage here for decades. all their money. so if you look at this graph which covers a period of 50 years, you can see that water levels are dropping in many areas. lemon douglas versus thinner. for more than 20 years, ground water levels have been sinking more noticeably across germany, enough to dry out an inland lake, for example, a little so it's quite horrifying to see seconds within the flu. is shawn? it's something that when i think of my children, is going to be a big problem in the future, or lumens of some get for the diving school at lake styles. that problem has already arrived. stephan kavitsky is heading to

a training platform. a few years ago. it was at a depth of 4 meters, and now his computer shows it's now just to me to 7 deep the platform that's used to practice rescuing people from the c bed, for example is now no longer deep enough. but the diving school instructor says climate change isn't the only problem here. he criticizes the local water authority that draws on ground water for public drinking supplies and local industry was ruined. andrew, what i'd like does what i'd like people to take her seriously and also ask to hear us and do something about the water shortage, which is being caused by human behavior. ah, for the fog would settle it, but he's worried things will only get worse. now that automaker tesla has moved in testers, 6000 square meter giga factory, sits in a water conservation area and consumes as much as a small town. i'm with hello hintock of harm. if you've got to bear in mind that

there will be expansion, and that will bring further influx, fully financed. you've got the automotive supply industry and a whole raft of people who will move in and they will all boost water consumption. oh, for was at the lou say lake. the moreland is parched. forrester peter pollack has been watching the developments for 20 painful years. it makes him angry, frustrated a bit sad to polly kurt the official explanation is climate change, although it's never been thoroughly investigated. but groundwater here is being pumped out of the region. peter pollack tells us that a major part of that water goes to one of brandon berg's biggest tourist attractions. the tropical islands result result managing director thorsten christopher young. doesn't see a connection whereby um, yet from fairly just because we happen to be in the move is a region which has now dried out. i don't think we can take the blame for it. i

slew dependence void without submission because we have done the beauty of and continue to do. yeah, others, all we care to take an alternative approach. i don't know to leave out to say some 80 percent of the pool water is recycled using state of the art filter technology. but one fundamental problem is that many of brandon bergs groundwater exploitation licenses were issued more than 30 years ago. long before economic mega developments like tropical islands or tesla arrived on the scene. now back to the base, recreational divers and diving instructors are in agreement about the ground water laundering. a change of approach is necessary. we have to rethink things. our resources are limited. we need to take care of what we have on auto versus how this and his or does it look like. it's simply not the case that we don't have the chance to enact

a better approach. we're just not doing it of the amazon. and it's also a problem that those who make the decisions are hard to reach and can comp. as the result, more and more often, decisions are being made to help expanding businesses despite climate change and the dire consequences for groundwater and the environment. in addition to climate change, rapid nobela zation is a key driver of water shortage. a city on the outskirts of one by has founded increasingly hard to secure a stable your round supply. we met one man working to revive a centuries old water collection network that has the potential to solve the problem. oh, these women's families have been farming this land for decade. they belong to integrate in community in by say, the down 20 kilometers outside one bay city limits is feeling the pressure of globalization and it's water supply is under threat if, but just as wasa,

we can som without it, we wouldn't have livelihoods. ringback over the past 70 years, my face population has increased 17 fold, due to an influx of migrants drawn by jobs and moonlight. to day, the town is home to more than 2000000 people, but its basic infrastructure. ringback ringback like the supply of clean water. ready has failed to keep base, we observed, i'm a 43 year ordinal, and we observed that the development was only in the dumps all the buildings and bringing the population here. nothing is absolutely nothing of that is know that a fountain, no varnish, or they know the basic requirements, lake of water, the electricity, the lord of the bronze borders has done the blended system. nothing. and of course, the main issue is the drinking water that says mix of oven residential and farming populations rely on the same. what a supply half comes from distant dams. the other half is delivered by tanker

operators, community taps and bells that drawn local ground water. a finite resource that needs regular reasoning. such a mighty has lived in my say on his life. he believed the town hall is the key to solving. it's what a problem. by tapping into a defunct network of artificial, what a body's called balcony was 8 us on that. and because i received about 2000 should 2200 milliliters of rainfall every year. since the land itself has a slant from east to west time. most of this water naturally runs off into the ocean of order to conserve this run off water and to make it available for human use. our ancestors crated man, made lakes and balconies. lo, i knew balcony continued nikki. oh, bow cuz we're built all across la. say 200 years ago, but became increasingly neglected in recent decades. many were filled up for the construction of houses and apartment blocks. and with fuel wilkins, engaged in farming because came to be seen less as an essential water source and

more as dumping spots the waste well, as i dug deep in order to draw water from underground aquifers, bough cause a shallow with a large surface area. the optimize the collection of rain, water, and allowable collision to replenish aquifers. such in my di singlehandedly began working to raise awareness about the essential rolled bow, coldplay in detaching the ground water aquifers. he has since recruited friends to help protect. and if i have neglected bogus, the organized cleanups and maintenance programs that involves the local community that i me just a place that'll allow me a thick organized zone that we go step by step to build consensus and plan action. we go to each house near the bow call and explain our ideas until we meet together

and finalize the plan. oh my god, job register knew she did was i was then we pick holidays to do the cleanups. so the younger people can get involved a garden, as every traffic article on him of came on the work can take 3 to 4 hours a day and last 2 to 3 days at a stretch for lug. but i did, i do, she is off somebody's whole programmable of cleaning is only the 1st step, the volunteers then blunt need to vegetation, to restore the bulkhead surroundings. deacon, suddenly a by households and urge them to stop dumping garbage in the pond. finally, they looked to divert waste, bought a drains away from the bulk of the entire process, is been sneaking and can dig up to 3 years of dedicated book when completed about kelkins store water recharge aquifers and boost biodiversity by attracting an airy of species, enduring reptiles, insects and birds o,

until now such and mighty and his friends have successfully restored eat balconies in different parts of a site. ringback and militia, thumbs up on ye. bow collier was i, he's on the, in the future. you know, if we don't take care of the remaining 800 bell calls night, people here could face the situation. sir, myrtle chan, i think you were. groundwater has completely run out of georgia, is you could as brazil, j this umbrella bo, but unlike big cities such as china and mundane, lesaine has inherited a li to steve off the water graces with its network of balconies. such might be wants to lighten restoration effort by convincing authorities and mondays residence that there is a treasure under their feet as valuable as the buildings they call home to latin america. now we're water shortages at a factor daily life. in the costa rican capital of san jose, who had seen plenty of room in its wet season openings, ition deforestation,

and agriculture are disrupting the city's water balance. no matter how much i had a ruby turns, the tat nothing comes out. he'd like to wash his hands after a long day at work. not there was in court often we've had water in the morning before work, but then not in the afternoon general in order of the family to nothing comes out of the tap. and then we have to wait until 678, or even 9 at night before we get any effort, if the, if thou. so the dishes will have to wait too. it's the same for this entire neighbourhood. one reason is increasing urbanized zation. there aren't enough pipelines and a modern water treatment plant is still under construction. over half of costa rica population lives here in the greater metropolitan areas surrounding san jose. increasingly, it's encroaching on nature. if the real,

this river originates high up in the central volcanic mountain range, but in the middle of the forest it but immediately runs from farm land and meadows . new stories love star, a. look it then right after that comes the edge of the city which is steadily creeping. aquila, but they are gonna like and i it up and straight after that it gets swallowed up by the dense urban area cuz it can be out there in when i saw an awful van of about manuel guerrero's water fund, agra t co works to protect water source is by bringing together pharmacy public institutions and civil society. and you can drink the water from this river. it's completely contaminated in many places, toxic chemicals are dumped into it for you. ah, a went this a yes and the lake that's a waste from agriculture. what the breeding of livestock waste from urban areas or industry is all discharged into the river le industry. alice found

a forte though. oh yeah, no, there is no system in place yet to treat the water properly, and there's no system to collect and reclaim the water. that'd be the us read through all if you i'd, i'll up blank. but i mean treating the water is one thing. but manuel guerrero and his partners are mainly concerned with how water is used and protecting the supply . so they work with farmers and support their efforts to develop sustainable farming methods that includes protecting woodlands. 3 decades ago, large swathes of forest were still being cleared to make way for grazing land. to day, the farmers know that forests a key to protecting water sources. this farms 200 cows are always put out to pasture in different places to give the grass time to recover. this also helps to spread their dung and urine more evenly reducing water contamination. thinker

roblis is a model for sustainable farming in the region, especially as the effects of climate change become more obvious within it, they are mentally cambia clean. must have we're definitely affected by climate change. yes. in that it rains less now here's how it and we used to get more rain, especially during the rainy season cycle. and the dry season is now dryer still and say over the years the climate has changed. okay. had passed, but then and when the grass doesn't grow, we have to buy feed and that increases our costs, located nothing claim and then those costs ah, carla brailey and her family have committed to keeping one 3rd of their farm covered with whitland. in return one of agra t cuz partner organizations pays them compensation equaling roughly 5 percent of their income

a was as it had been for the front of what can the forest is so vital ask because that's where the water reserves we rely on. i found both, if i more, there are many water resources in these woods, the trees preserved this water by absorbing it up that is. so for us this results is hugely important. so it's open put a bank, and those are funny to combine pastures woodlands on our terrain. and the trees provide shade in some places and conserve water and others. i don't know if i do long articles here to buy a la pharmacy transform part of their land into a forest ecosystem. can play a key role in protecting costa rica. water supply says manuel guerrero. yeah, those are they just some, in the farmers realize that they stand to benefit from adopting these environmentally friendly practices and moving away from traditional style intensive farming enough, which produces many harmful substances practica unless i'm godless, while i mean you can both as

a rule sca and this then reduces the sources of pollutants entering the water of young. yes, on the deck. that's what he put us. so de la mueller went to the island, but there's still a long way to go before that will soon be sure to reach the cities at 6 o'clock in the evening. ricardo rubies still hasn't seen a drop more in our we're is similar. we are, the water is the symbol of life. while one of the boy you can't live without waterfalls. if it's frustrating factor. that he at least stored a little water in advance, both for himself and his 2 dogs. he collects water for them in plastic jugs. because here, every drop counts, expose beneath was of the future will be fought because the water are extracted actions already affecting people around us. today. 2000000000 people live in countries experiencing high water stress. what are you doing to make sure the duck collective access to this basic need is not threatened. do let us more eco,
