all the ideas is on its way to bring you more conservation. how do we make cities greater? how can we protect habitats? we can make a difference. global ideas, the environmental series in global $3000.00 on t w and online. ah, water it would appear is nature's most renewable resource, raining down on us from the sky to replenish reservoirs above and below crowd. but more and more places on our planet phase, serious 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, changing agricultural practices and inefficient. what are use are impacting the foot? i'd gung gabby said, with supplies about half of the countries koreans what can be done to save india's food basket? we met researchers on the quest for answers. ah. the ganges river has been a blessing for many people in india, for centuries, and not just for religious purposes. the river supplies of water to numerous cities to day the ganges along with its tributaries, forms the most densely populated river basin 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 month. m 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 stay dependent on when a values play the print, let me look at a downstream danishes, farmers among the last recipients of water from the areas irrigation canals. previously, it was a primary source of surface water to day sitting and neglect have left these channels 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 $150.00, 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 a 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 center has included the pondered 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 esteem, want 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 translate 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 terminal and high, but spectral cameras allow the recording of the smallest tinges from rainfall and soil moisture to press the partition and crown water levels. 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 know,

some of the satellite information to see how we can compliment. that's my observations, with their very dense sense and network in the see at our regional satellite data already important for the scientists and con, pulled the analyze it and informed the farmers about the results and actions to take. one of the key masses is 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, and a given time that i, that in knitting the, every time and learning the bomb, going to vote by service to batter managed to 1st 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 scientist for his farming work. them 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 way we know 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 desktop and they take samples from both. so we end up learning from them later assembled, particularly that for 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 in 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. and the gun, gar, biesen is something that's also 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 click here 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 here 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 stefan 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 light minutes institute of fresh water ecology at magazine. here, eco hydrologist. doctor yog, live and of 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 see it yet, this is already having simple consequences for forests and box chief forrester jo dilner is on his way to the luke say lake rhythm district. forrester peter po lake,

leads him to a spot where just a few years ago, they would have got their feet wet. because this bog is a living body, one that shrinking understanding here, my boots are getting wet, but it's actually 2 meters below the water level that the lake used to have. 3 of us are shunt beach puffinburger, either by mutual. in my case, my head would be under water, but that shows you the extent of the situation on yonder duluth. 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 foresters spot another problem, the huge structure nearby, 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 em. 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 mouth in march. there shouldn't be any risk of fires. scientists have been tracking the growing water shortage here for decades. or vermont, if you look at this graph which covers a period of 50 years, you can see that water levels are dropping in many areas. liam, and they're going to us our spinner. for more than 20 years, groundwater levels have been sinking more noticeably across germany. enough to dry out an inland lake for example. well, it's quite horrifying to see seconds within the flu is on it. something that when i think of my children is going to be a big problem in the future. probably musical, some get for the diving school at lake styles. that problem has already arrived. stephan. gov it's scott 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 restaurant. andrew, what i'd like just thought i'd like people to take us seriously and us will ask to hear us and do something about the water shortage, which is being caused by human behavior off of a 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 our own 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 it 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. it was a poet, 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 bugs biggest tourist attractions . the tropical islands result result managing director thorsten christopher young doesn't see a connection who of while i'm yet from fairly just because we happen to be in the loop 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 them go to his and

continue to do. yeah, others. all we can to take an alternative approach either not even 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 random bugs 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, are resources are limited. we need to take care of what we have one daughter rose high as any sort of dismiss little kids simply not the case that we don't have the chance to enact a better approach. we're just not doing it again with her. and it's also a problem that those who make the decisions are hard to reach and shrunken. 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 wrap, and urbanized nation is a key driver of water shortage, a city on the outskirts of one by has found it 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 decades. they belong to integrate in community embassy. the down 20 kilometers outside more by city limits as feeling the pressure of globalization and it's water supply is under threat if, but if there's water we can farm without it. we wouldn't have livelihoods. ringback

over the past 70 years, my se, se population has increased 17 fold, due to an influx of migrants drawn by jobs in moonlight. to day, the town is home to more than 2000000 people, but its basic infrastructure. 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 of the buildings and bringing the population here. nothing is absolutely nothing. it's that is nor that a phone, no varnish or 3rd of the basic requirements, lake, a water, the electricity that a lot of the bronze water has, has been the berman system, nothing. and of course the main issue is the drinking water. ah, the says mix of urban, residential and farming populations rely on the same water supply. half gums from distant dams. the other half is delivered by tanker operators, community types and wells that drawn local ground water. a finite resource that

needs regular reasoning. such a mighty has lived in must say on his life. he believed the town hall is the key to solving. it's what a problem. by tapping into a different network of artificial, what buddies club balconies, ah, was aid. a saw that on the sy receives about 222200 milliliters of rainfall every year, which since the land itself has it's land from east to west time, most of this water naturally runs off into the ocean. now we've got to conserve this run off water and to make it available for human use. our ancestors crated. manmade lakes and balconies. hello. i'm balkan antonio nikki bow cuz were 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 fewer, lucas engaged in farming. mach has came to be seen less as an essential water source and more as dumping spots, the waste wells at dug deep in order to draw water from

underground aquifers. bough cuz a shallow with the large surface area, the optimize the collection of rain water and allow book relation to replenish aquifers. such in my di singlehandedly began looking to raise awareness about the essential rolled bow, coldplay in detaching the ground water aquifers. he has in secret, at friends to help protect and drive. i have neglected bogus, de organize cleanups and maintenance programs that involves the local community that i me stay for his dental. oh, a lie me a thick. oh god zone. and 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. i knew she did was that it was then we pick holidays to do the

cleanups. so the younger people can get involved. i got an, as having tried to cut it off. i mean, mother 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 this out. surveys overcome roblis. cleaning is only the 1st step in the volunteers, then blunt neat to vegetation, to restore the bulkhead surroundings the consult near by households, and urge them to stop dumping garbage in the bonds. finally, they looked to divert waste water drains, away from the bulk of the entire process is been sticking and can take up to 3 years of dedicated book. when completed a balcony stool water recharge aquifers and boost biodiversity by attracting an array of species, enduring reptiles, insects and birds. ringback o, until now and such, and marty and his friends have successfully restored 8 balconies in different parts

of the site. are bobby shut thumbs up on easy bow collier was they? he's on the, in the future. you know, if we don't take care of the remaining 800 bell calls, nice people here could face a situation similar to chin. i think you were. groundwater has completely run out of georgia, is you could ask virginia to somebody like but unlike big cities such as china and mundane, lassie has inherited a li to steve off of auto crisis with its network of balcony. such might be wants to lighten the restoration effort by convincing authorities and massey's evidence that there is a treasure under their feet as valuable as the buildings they call home over to latin america now, where water shortages are the fact of daily life in the cost of he can capital of san jose, who had ceased, plenty of them in its wet season openings, ition, deforestation, and agriculture are disrupting the cities. water balance no matter how much they

cut a ruby turns, the tap, nothing comes out. so he'd like to wash his hands after a long day at work north him was in court. often we've had water in the morning before work. well, but then not in the afternoon, joe, in all of them, apparently nothing comes out of the tap. and then we have to wait until $67.00, about 8, or even 9 at night before we get any output, if the if so. so the dishes will have to wait too. it's the same for this entire neighborhood. 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 live strata a locust then right after that comes the edge of the city which is steadily creeping. aquila but they unequal. like and i had up and straight after that it gets swallowed up by the den suburban area cuz it can be out there in when i saw an awful van of about manuel guerrero's water fund, agra t her works to protect water sauces by bringing together pharmacy public institutions and civil society and you can drink the water from miss river your it's completely contaminated in many places, toxic chemicals are dumped into it for you. ah, a went with a yes and the reg, that's a waste from agriculture. what the breeding of livestock waste from urban areas or industry is all discharged into the river left in the sea. alice found a forte though. 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 be awesome or through i'll, if you, i'd, i'll up blanket up. 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, the forest was still being cleared to make way for grazing land. to day, the farmers know the forests sack 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 that in it they are mentally cambia heckling must have. we're definitely affected by climate change. yes. in the it rains less now 2 years. how it and we used to get more rain, especially during the rainy season cycle, and the dry season is now dryer. still that, that i with the finance, i mean over the years the climate has changed. okay. help us both and. and when the grass doesn't grow, we have to buy feed, and that increases our cost. okay, and i think i'm in fennel's, costa noon, carla brailey and her family have committed to keeping one 3rd of their farm covered with whitland in return one of ag, what he cause partner organizations pays them compensation equaling roughly 5 percent of their income a was bigger than the for the month of what again, the forest is so vital. westgate 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 preserve this water by absorbing it. they've got that. so for us, this results is hugely important cortisol, it's open, put about in those. they're funny to combine pastures woodlands on our terrain. and the trees provide shade in some places and conserve water in others. i don't know if i do long arcos hit by a la pharmacy transform part of their land into a forest ecosystem. can play a key role in protecting costa rica as water supply. says manuel guerrero. yes. those who they just. i mean, the farmers realised 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, my family godless. while i mean, you can both as a rule sca and this then reduces the sources of pollutants entering the water and

youngest on the deck. thus when he was us. so de la muma 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 way if see maria water is the symbol of life. while one of the boy you can't live without wanted of if it's frustrating, but 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 out 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 india at to d w dot com until next week?
