A month we have to come out and really trim things. It just depends on the season. 09 years ago they decided their front lawn had to go. It required too much water an offer from the region of san diego came at the right time of 43. 00 bonus per square meter from the water authority. All this was long. This was all grass. And its about 1700 square feet. We took took it all out. This is all the bags them all tied by. Thats going to cover this whole area after the plants are for the cabin hours, the transformation has been worth it. They only had to put 50. 00 of their own money into the project. Theyre trying to get others interested. But not everyone cares. Some still have alarm that needs regular watering. War, they have artificial turf and rock garden. Its seal off the ground. It makes nancy angry. I always on it to save the planet. You know, its kitty. They even try to save water at home. Something also supported by the city. I. At 1st glance, everything looks normal, but there are water saving toilets in the bathrooms, as well as special showerheads. More than 600000 residents have registered with the city to take part in the program. And any little bit i can do to out my daily life, whether it be in my background, where my kitchen, outside in my yard it does tiny steps. Its only baby steps you have to take to try to conserve on monitor. Ah, the drought is here to stay. California has been suffering from a lack of water for 20 years. Any land not being watered, turns to desert, saving on drinking or ground water is no longer enough to meet the needs of cities on the u. S. West coast, thats why the worlds 2nd largest Desalination Plant was built here outside san diego. Like engineer nathan faber shows us the plant, see that he knows its Energy Intensive, a target for criticism from environmental activist. But he also knows theres no alternative and also i could be surfing in the ocean, and 2 hours later, the water is converted to Drinking Water and going to the residence of San Diego County. Wow, its 2 hours. The plant turns 190000000 leaders of sea water into Drinking Water for the region every day. It flows through 16000 filters in this pipe in a process called reverse osmosis. Is one strategy of many for securing enough fresh water. So since the ninetys are parson, water use has dropped in half, even though our population increase. And weve had these suppressors like Climate Change in route, one of the main factors is education. Teaching people in San Diego County resident audit use less water and be more efficient. So with irrigation, which showers really just changing their attitude toward the water . Use the city overseas, 500 kilometers of pipes, using sensors that found an alarm if theres a leak anywhere. Nathan favor is convinced that the measures being taken by the city work well together. Its extremely critical. The stress test showed that until 2045, and maybe even beyond that, the region has adequate supply. Weve invested in storage, weve invested in desalination. We looked at recycled water, collecting water and purifying it next to saving water. Its the issue in the san diego region, especially because it only gets around 25. 00 centimeters of rain per year. Emily and chris ear save every drop in 2 large tanks. Thats enough to take care of their garden. Theyve created a green oasis with lots of fruit and vegetables. I fear for the day were is the only way to go where we have to grow our own food because theres gonna be such water shortages in the future, especially in the western states here. This is an ongoing crisis out here. So its, its, makes a ton of sense to, to use water intelligently garden, designer brooks, arson installed and irrigation system. Under chris and emilys beds, the transports water from the house, directly to the fruit trees, how much laundry water they would be using every week. And we decided that would water about 3 fruit trees. So there is a lot of nutrients in that grey water from the soaps and from whatever is coming off of our clothes. Ah, its basically like free fertilizer depending on whether emily uses bleach for washing or organic detergent, this lever controls whether the waste water is pumped into the store or her garden. So this is actually feeding the root systems below, and its also helping feed the entire main area around here and keep the, the ground more hydrated. Like many san diego residents, theyre combating the drought any way they can because they have no other choice. Its something we all have to do. Often, moulton, once a day in germany, an average of 6 liters of Drinking Water washes the contents of our toilets down the drain, roughly a 3rd of the per capita Drinking Water consumption of 128 liters is simply flushed away. And its not just water. This wasted human excreta contains many important nutrients, which could perhaps be put to better use. Take phosphorus, its essential for plant grice each year. 50000. 00 tons of it end up in Sewage Treatment plants. Many countries are already starting to use human feces to produce bio gas and research is underway into its potential use in agriculture. Thats not yet permitted in germany, but a revolution isnt away. Time for the morning trip to the toilet up is Music Festival in northern germany. These toilets are collecting a valuable resource fecal matter. Here its not considered waste, rather a rule material during the summer sanitation startup veneto has been sending the toilets from festival to festival that explains the empty hole at the companys office in evas volunteer. Berlin, leaving c e. O. Florian augustine, with time to tinker. The washed alaska raw materials, were talking about our urine and of course a feces thats collected here in all just enormous amounts of nutrients. Its good stuff that comes out of us. This is complex. I thought, you know, i wasnt, but we just flush it away and dont want to have anything to do with it. But its something we really have to start dealing with again. Ah, continued on, so they are thats exactly the goal of the state sponsored research project, sir. Failure bar, which benito is also a part of a v i. A cows are coordinates the project for gather human waste from public toilet, and turn it into a usable resource. Instead of flushing the waste with water, its covered with pulverized straw. I can do a demonstration as if someone were peeing and it inside the toilet. The urine runs into a separate container. That means the feces stays dry. Keeping them separate makes them easier to purify. One extra good element of the project is to collect human waste and to bring the nutrients in it on to the fields as fertilizer. Theres huge recycling potential in human waste aspect. Circling, Balance Research happens here on the edge of a this valley. This is where nutrients such as potassium, phosphorus, nitrogen, and many others that people excrete every day are being recycled. Turning the plants that feed us back into fertilizer, the collected fecal matter is combusted along with green waste and transformed into human fertilizer agriculture. This followed by men after why did we want to recycle new transport . If we look at mineral, such as phosphorus or potassium, we typically get them from mines. And when it comes to phosphorus, resources are extremely scarce. Nitrogen is another neutral that will really need to be recycling because its an essential nutrients that every plant needs to grow. And that would normally be extracted in an Energy Intensive way. During composting bacteria create heat. So were currently at 67. 00 degrees up. Her goal is to reach 75. 00 degrees because thats when you have the greatest an activation rate for pathogens out of her con, guzzling up killing of the pathogens is key. Thats just one of the things monitored by claudia costing of lap team at the bio Mass Research center in lexi share my telephone. Heavy metal should definitely not be present. We also check there is no mercury or lead or traces of medication or resistant germs, that when all goes well, theyre usually killed off during the purification process and the temperatures in the compost. If i opportunity regulations in germany currently forbid the use of human waste in agricultural fertilizers, thats due to hygiene concerns. And thats when your pipe, we want to show that its safe and that its possible to eliminate pollutants and comply with all the limit values in line with the regulations in effect. And to show that after the composting and purification processes, you can use this material as fertilizer on fields. Id o simply following her initial analysis, Claudia Kirsten is optimistic sulkily of our receive special permission to use its fertilizer. Now the corn on the trial field is ready for harvesting earlier than expected due to the drought. The soil mixed with the experimental fertilizer appears to have done a better job it supplying moisture to the corn than the untreated soil. Safely above plans to focus next on using urine as a resource, which right now still has to be disposed of in the sewage system then hm. The exit perfect. The carmel would actually be the perfect combination. If we were able to bring all the nutrients we excrete together again in the form of agricultural fertilizer thats used to produce more food added. This now has a good smell of soil. That means for composting has gone well. The material has turned back into soil ada. The team is working on improving an automating urine composting in order to start processing larger amounts. Ionic houses and florian augustine, never lose sight of the big kitchen to make their products so good and so clean that theyll be put to use on fields on the festivals of providing more than enough raw material with ah, 2 children to countenance one giant problem. And molina in on it is she, a bit chilly in the miami navy will be tracing delay food. Exactly. How will Climate Change affect us and our children learn more at d, w dot com slash water. Its time to head to thailand, to replace the sink. Ah, bangkok, over 8000000 people live here in the capital of thailand, but even more come to visit with over 20000000 tourists arriving every year. Hancock is the most visited city in the world. One of the things its most famous for is it st. Food. Its always busy at amada, market. Sassy gone . Some. Ron opened her stall here one year ago. She sells a snack. Many people love, but only a few still make. Come home crock business is good. Quad and i chose to make this snack because its hard to find and i like eating it. So i studied how to make it the dough is traditionally made from coconut milk, rice flour, baking soda, and a little sugar. The recipe hasnt changed since it was 1st invented, while the halves of the dough balls are baked in the special con um cropped, pan sassy thorne sovereign takes care of the toppings. In addition to fresh coconut shavings, theres corn and spring onions on offer. After about 5 minutes, the canon crocks, or golden brown crispy on the outside, but still soft on the inside. The haves are cut out individually, then assembled into balls. Theyre sold in cardboard boxes of 7. 00 to 10. 00 pieces each for the equivalent of about one euro and 0. 10. Sassy lorn sam ron doesnt just like making the snack she enjoys eating them too. Oh wow. And people like eating it because the flavor is consistent and traditional making. You also get the nice smell of coconut milk. Let them think that and the texture of the colon and coconut makes it mellow and delicious. I sassy thought some. Ron sells about 50 pans a day, like the recipe. The spiritual shape of cannon crocks hasnt changed a bit. Literally translated con on crock means, snack mortar. While a mortar is not used to prepare the dish, the round shape of the snacks is like that of a mortar bowl. And so the tradition still lives on today. Over time, only the savory fillings have changed. Oh, no, never. I see the snack. I buy it immediately. You know . Wow. When i do, i love you to eat and its tasty. Its anti snack that i often a growing up and i, and even now i still eat eat, its not messy and its easy to eat. Cannot crop taste best when the balls are still hot out of the pan. Enjoy an average of 19. 2 kilos. A fish are consumed per person per year. Thats about twice as much as 50 years ago. There are also twice as many people on the planet as back then, which means that overall Fish Consumption has effectively quadrupled the u. Ns, food and Agriculture Organization reports that 31 percent of the worlds fish. Stocks are over finished. Could aquaculture be the answer . Today, half of all the fish we consume comes from controlled breeding farms, but that doesnt always mean it sustainable. The construction of fish farms often means the destruction of natural fish habitants, chemicals, antibiotics, and excrement create pollution. Conventional agriculture also contributes to over fishing. The farmed fish are often fed wild fish and not all marine creatures can easily be bred in captivity. We had to mexico, where scientists are trying to do just that with one particular local species. The octopus, a type of several. A pod is a fascinating creature. It has 3 hearts and 8 arms. Those arms also contain most of its brain with 500000000 nerve cells and real superpowers. Octopuses are highly intelligent, depending on their environment. They can change their shape, color pattern, and even the texture of their skin. When they can turn into rocks, looking like theyre covered in algae or make themselves huge and turn completely red williams, the needles, the raw hole and an anom University Satellite campus in the mexican coastal town of seesaw. Biologist carlos rose. Us is researching the octopuses ideal living conditions, william m. U. Results. So far, the sensitive animal reacts dramatically to rising water temperatures by laying fewer eggs. This could become a problem if Climate Change progresses or in the us having what we know today that the caribbean, c, m, the gulf of mexico are warming because of Climate Change. The way we want to create models that can predict whether the number of octopuses will decrease in the future, gave environment above even im in oregon, feel if there are still plenty of them here along the coast of the yucatan. But that could change demand for the low fat delicacy is rising worldwide. And in some asian regions, theyve already been over fish for octopus catcher. Antonio cock in cecil business is better than ever this season. It always depends on how long you want to work it. So im usually full by 1 pm, and i earned around 5600. 00 pesos. The people who stay out all afternoon make 2000 or 3000 pesos, either or to the worth of gravel. A barbara is anybody, is dr. Lisa. But antonio coffee is also worried about whether extensive fishing can go on forever. Thats why hes working with the universitys scientists to sell octopus raised in a breeding station instead of capturing them out at sea. Is this is this, or who isnt . Its an ambitious project, but it will work. Moon when we, when we, when rub off was or not. I was a good recall fortunate farming. Octopus is one of the Biggest Challenges facing the global seafood industry. Unlike salmon and shrimp, theyre sensitive to captivity and die quickly. But the mexican researchers have one advantage the local species the maya is particularly robust. Home will be those misses this one is already 2 months old as thus per seal copels mother. As the maya octopus is a very pleasant specie, little out of, for me, they dont one thing. They have no problem being in these tanks together. Thank no song wed better cody as they get along very well and god bless. And besides, they dont emerge from the angle of females. Hatches larva, but as are fully developed, its tiny octopuses song when people gather sarielle, other octopus species are born as para larvae at that stage of development. Massive numbers of them tend to die here and see. So where the hatchlings skipped the larval stage, they breed surprisingly well. The heart of the University Station soon knew little maya octopuses will emerge from these eggs. If you look closely, you can see small black dots, the tiny eyes of the baby creatures and new eggs are already on the way. Again. Animals level 32. 00 tanks here and each one there. So pregnant female think were now were waiting for them to lay their eggs. Some of the food on rucker . Yeah, this whole the scientists capture the pregnant females in the open sea. Theyre just one year old and die after laying their eggs. They starved themselves to death, here in the breeding station, as in the wild, but keeping octopuses in captivity, even if only at the end of their lives is always a source of controversy. The animals are so intelligent that critics consider it morally wrong to confine them. Carlos rose, us sees things differently is good. Ill put both hello money saddle. Weve anthropomorphized the ought to push through movies and other stories that are spread, the full mother equal. So unless he and thats a problem. Yes. Or is that the good . Ok, this is a problem in southern mexico, the octopus is regarded as a resource. Its a source of income and food for many people in the village. I would it in a moment, youll see how delicious this is or the cock family is having it for lunch today. It was for voice like hearing a in here in yucatan. Youll be offered. Oh i do is i every way you go is also in restaurants in a little the thought on face. Sylvia cock serves fried octopus with her eskimiya che sauce. In other mexican regions, octopus is served in sushi, a popular dish in mexico. The worlds appetite is huge. Some 420000 tons of octopus are eaten annually. Antonio and sylvia caulk come to the anom University Research facility every day, and volunteer to help raise the octopuses. Theyre learning how to successfully breed and raise them in this artificial environment. On your point. 1. 6 grams wing of 1. 8 grams. Las vegas, the very small ones get stressed out very quickly as well. The scientists focus on their research and collect data. Antonio cock and his wife have now founded the maletchko. So my ab cooperative to expand, octopus farming. Commercially, the other catchers in the village were not very enthusiastic about the project. At 1st. A youth, lithium, they said it was crazy. Just a waste of time. Its alarming in us up and then they didnt believe in the project. I am now almost 10. Octopus catchers are organized within the cooperative with the help of support funding. They were recently able to finance their own site. The tanks are already in place, but they still need money to get things up and running. I was telling was expand our project so that we can increase our market, i think, selling nationally and internationally. Thats my dream in the money preferably starting tomorrow for this project could secure the future for many fishing families and perhaps become a model for other regions affected by over fishing and Climate Change. And that so from global 3000 this week it was great to have you with us, drop us a line and tell us what you thought of the show. You can reach us at global 3000 at d, w dot com and we are on facebook to dw global ideas. See you next time. Take care. Ah ah ah ah ah, using tom to combat particulate matter. Researchers want to purify the air with natural method. The results from preliminary tests conducted under real world conditions, ah hope and is this cleaning method also useful on building experimenting to create a better quality of life in cities tomorrow to connect w o. M. When you work as an architect that go all in or not at all, women in architecture. Why are they so invisible to the larger public . We decided to ask them. And if women grow up with insufficient little models, they cant identify with certain professions about their guiding principles. Massis i, what is the poetry of the secret of a house . And im house about their motivations. I think im gonna texture does so much to you in the real goal of the architecture is to create habitat for human about their struggles and dreams. Responsibility is huge. They have so much to with shattering the glass ceiling. Women in architecture dismiss has to be really, really good. Start september 30th on d, w. Creating a green oasis inside a road tunnel. What can this experiment teach us about making cities more livable thrust stress in the city . What effect distress . Half on all bearings and good mood, food come what you eat, make you happier
