7:15 pm
salt marsh, and here there was no salt, much in front of the flood resulted in 2 breaches here, of differing sizes. this fragile looking marsh grass has been shown to provide protection against floods, which due to global warming, are set to increase in both frequency and intensity. thinking if you live in a low lane, can see like the netherlands, you will never be able to live there without dikes or bits. bits. sheila for rice and accelerating sea level rise maintenance and constriction of dice will get increasingly more expensive and to be able to keep up with the sea level rise to to keep our float safety stand. the said to keep doses with sheila for ice . nature can help us a lot a bit. we should not be dreaming and say, well we can forget about the engineering. but we have to make smart use of nature
7:16 pm
and combination with engineering. and you can really see that the growing awareness of the problem is sheila, for rice also leads to a growing awareness that said there is a need for a transition in how we cope with flood safety. and so there is a growing willingness to, to think about alternative solutions in which nature plays an important role. boma uses this wave machine to illustrate the principle to doctoral researchers. course of mark levies without chord grass erode faster. and because she well, i was trained as an ecologist, but i always show her birth as a kit already on motorcycles and all kinds of technical stuff. and so i like to play with and very happy at that point when we were designing these that we had
7:17 pm
a technician that came from industry, it was really good to implement it. so we were discussing how do we get something that makes waived, and it's cheap because we don't want one perfect wave machine we want to have multiple so that we can have replication, session variability, show important quality. so what you, she gets the big wave hitting there, and then the wave goes back and reflects several times. and by that asian metric movement of the way, federal, we get to really realistic, irregular waves. and that's the magic in this book. so the scientists firmly believes that court grass is a viable solution for coastal protection. oh, the challenge now is how to plant the grass in mudflats without it being washed
7:18 pm
away by the north sea tides. it may be hard to imagine it now. it's completely dry and the water is far away. bitter in 3 hours. sure. from now it will be completely flown with again and 3 hours before it bo, social floating boma and his team have developed an inventive and environmentally friendly construction. for the purpose, a lattice structure made of potato starch. so dish will help us to widen the marsh, and thereby exactly, yeah. so at the flood defense, this is a clear test. that's if we can support the growth of the seedlings early in their life cycle by securing their routes zone. and we can allow the mature plants to grow much deeper in the title frame, which means that marsh can expand and he longer have more protective benefit for
7:19 pm
our diets. meanwhile, on the global scale, there's a growing urgency to enhance coastal defenses. and at the same time, slow down climate change and see we could make a notable contribution here among its champions, his eco physiologist class tim amounts under t. c. c weed. as an excellent meat substitute. and it comes with a big advantage. unlike in the meat production industry, the plants emit 0 carbon dioxide point one. on the contrary, this is really the basis of the food chain. so, so are organisms like this day, you sold are lights, c, u 2 and foreign bio mass. so it's is the most simple way of forming bio mass and they're, they're really on their own. they don't need anything else than that. so it's the
7:20 pm
most efficient way to produce food. these plants stay growing salt water. there's plenty of sold water that out. a says shortage of fresh water in many areas and hence about these these said this bio mass has many characteristic to make for a suitable also to you this food for human, for him. but the problem here is that global warming poses a threat to all organic life, including seaweed. well, there are a lot of sea way to forest in the ocean. and with global warming, some of them just disappeared. so i want to know the reason that to disappeared and how much they can disappear to the polar all reducing c o 2 levels is key to putting the brakes on global warming. to say politically insisting that people abandon meet in favor of seaweed is hardly a feasible idea at the moment. as the scientist from the royal netherlands
7:21 pm
institute for c research themselves. now the generation and transportation of animal products is an area with scope for reducing greenhouse gases. and here to there was a pioneering project in the netherlands of floating farm in the city of rotterdam. hendrick compton supplements the feet for the resident cows with surplus food from supermarkets, carrots, apples and other unsold, produce another contribution to carbon footprint reduction. the water born farm is based on the concept of maximum sustainability through recycling. the minerva,
7:22 pm
this is gathering all the manner which is inside stable and then it will bring it to one point. and from that point we separated in width and dr. arts and i went to dr. parts. we make small pellets, which you can use as a fertilizer in gardens, for example, and the urine. yeah, we process it actually, and then we make clean water of it's it's, it's quite high tech. it's new. it's also our invention and had to do it like that . and then we can put it back into the harbor. all the water from the roof is collected and is it going? how with those 5 here is going down? it goes to our feller. there we are, we have a system which cleans actually the rain water, so it gets some at a dust and other parts out. and then from there we pump it up again and we found
7:23 pm
that as to the, to the water reservoir, actually for the house. the floating farm with 37 cows on board supplies, dairy products for 2000 residents in the immediate vicinity. so this milk does not have a sizable carbon footprint from being transported all the way from the country side to the city. the cheeses are stored below the water level in a naturally cool space, which again helps to reduce the farms, carbon emissions. oh, the project has been making headlines far beyond the netherlands borders. do by is interested. floating farms could become a unique dutch export product. but are they really the future? it's a scenario that the country is already preparing for conventional farming and coastal areas is that particularly high risk from climate change and rising sea levels? despite the extensive network of levy's water from the north sea seeps into the
7:24 pm
ground water farmer of them, fine horses finds himself fighting a battle on multiple fronts. over to mike, a method roast ish along we get route periods of of the last 5 years for were dry. i was off the market and that's bad for our product holes in order that i shouldn't . but then you sometimes get severe downpours with a lot of water in a very short time available, and that means having to pump it out with all of your off of wouldn't with, with the resulting deficit in farm production says class timmons could be partly compensated by a whole new kind of see how back in the lab at the see research institute. he and a doctoral research are looking at ways of extracting proteins from c. we'd animal class. she's the aim is to create supplements and other food products. if you want to extract larger quantities, then you need to buy
7:25 pm
a refinery procedure in order to break open to bio mass. so gets proteins can be extracted and by it sounds very easy. how hard can it be? but in practice turns out to be quite complicated. and we're trying new techniques now, for example, using enzymes for marine funky that can break open to via moss, so that the proteins can be released. and b concentrates together with his team. he's examining the reproduction cycle of seaweed. after dying, it regenerates through the fusion of female and male units called spores. the science of growing see wheat is still in its infancy. we can actually bring those together in specific crushes, so their meals and females, and we can cross those. and then we can actually cross, for instance,
7:26 pm
material from here and say, lawns and with material from norway, and to see what effect it has on and on the, on the how, how the copay she looks like. so maybe they grow way bigger. so a farmer has better yields, and maybe they have higher protein content or higher. sure content, for instance, for the bio ethno industry. so, and we actually want to breed forrest, yeah. specific industry uses. the scientists want to increase the harvests of marine farmers like yost vouchers, while the seaweed sector is far more advanced in asia, he sees massive potential for europe to his farm. and the village of copper line in the coastal zealand region supply seaweed to the dutch food industry.
7:27 pm
right now it says there is no she read in the house is behind is old kind of old. our bio moss is growing on the line. so we need to clean them to goes, the lines become too heavy and they take away all the lies and all the nutrients of the series. i think when people began farming and hundreds of years ago with thousands of years ago, they also run into things that they find out and, and optimize over time. we had novaire yet. so we need to know, we need to invent little things. we're still every one is walking and see where the still kind of byron, there's a lot of things possible with theory for human and animal health to regenerate soils, to met materials like plastic. so there's a lot of applications with see. now what we see over the last years is that the
7:28 pm
demand for seaweed is growing enormously. because see, reducing need lands. it doesn't it fertilize us. and it isn't in fresh water. she can feel gross, just are tired and need sunlight and need see or to and it did said the marine nutrients that are in the water. that's all so the see really doesn't need any other resource well this disease lot problems room. you don't all dis, scott from belgium is a chef and a self styled ambassador of algae. he hosts classes aimed at breaking down people's aversion to the feel and smell of seaweed. he showcases the plant as a refreshing ingredient in a gin and tonic or
7:29 pm
a healthy salad. and on that i hope a one year every kitchen, every store. after fresh see wheat, c rita powder is very good for ever everybody special. this one. with this, we have a retreat, dosa, we call it, and when you riots and another thing, temperature that was thesis like a beacon. no omelet it bacon. widowed bacon is a future food. if seaweed can be added to everything from gloucester and bred to burger's ankles, all another aim of the shaft turned food. innovator is to unlock participants creative potential for economy for either one of the huge with office
7:30 pm
tiered boma has made a trip down to the c or a field experiment. it's a big day for the team from the royal netherlands institute for see research as they prepare to launch his custom made waves simulator. it was designed by the coastal ecologist together with engineers. and is one of a kind of a honda tailored being, you know, the mobile machine has its own name, the moby weighs more than you can get out of the way we get out of the way down. if you think about safety, then also camera manner because the whole goes, you decide what they also told.
7:31 pm
okay. goodman wrong there, but i'm happy you're sending behind. it's helping to get up to really the problem was not the wave machine itself, but the wench. but there are no casualties, and the moby wave is also unscathed. the team now pushed the contraption to the edge of a small patch of cord grass before lowering it into the water out of marketing out in the days to come. it will help them to study the delicate c plants, properties blue, amish, long and daily commute to the institute takes her along one of the many dikes lining the dutch coast. the netherlands is a global front runner and coastal protection management. but the scientist warns against being lulled into a false sense of security for the netherlands, sea level change, i guess, is one of the biggest consequences of climate change,
7:32 pm
or at least one of the, the biggest things we're watching out for. because a lot, a big part of the country is below sea level and we have these huge dikes like the ones we're cycling are now that protect us. this area would be flooded otherwise. and with sea level rise, the risks of flood are increasing. so what our height that we now see only once in a century, by the end of this century, we will see that same water hides approximately every 2 to 10 years. so all of these water hides are, are increasing. we will see those much more often. ah, ah, the climatology has analyzed
7:33 pm
a range of studies on global warming and its consequences and concluded that sea levels are likely to rise $25.00 centimeters by the middle of the century. and that already disturbing estimate is merely the average figure. so in the netherlands, we are in a pretty privileged position. we have money and technologies to help us prepare against sea level rise. even though we are a low lying country, we have a very high protection level, probably the highest in the world for our coastline. but of course, there's other nations that are less rich and have less options to defend that coasts. and on top of that, a sea level rise is not the same everywhere. this big regional differences. so if wits, $25.00 meet centimeters on a global average. there's around the equator, it's typically higher than $25.00 centimeters per day. might get 30 centimeters already. and then if you're in a country like bangladesh, which is really low,
7:34 pm
really poor and doesn't have any protection against sea level rise, they, they are more in trouble. and actually they're paying the price for the the development we've already had in the western world. slung and lives near the institute for see research, but wants her address to remain undisclosed. she now chooses to publish her insights only rarely on social media to avoid the hate messages. and worse that she and her fellow researchers have been subjected to colleagues of mine have gotten thread said lots of of more famous climate change scientists. and they, they actually get threats and as even some in the united states, for instance, that have gotten death threats. i'm so really quite severe. i said,
7:35 pm
a real public figures, but in my case it was more like, are you're lying, you're selling. it's all not true, it's all. yeah. a bunch of lies. you're telling me, but there are now projects on the ground or rather in the water that have heated the projections of climate scientists. this little neighborhood in amsterdam was born in 2008 years before the u ends. inter governmental panel on climate change, recommended building homes on the water. it's a concept with a twofold advantage. there's no disruption to nature. plus, rising water levels are less of an issue for floating settlements. the vulcan, your family used to live in a regular apartment in a typical, densely populated and concrete clad urban neighbourhood.
7:36 pm
well, i mean it all started to be one person, me on the block see use a friend of us and she had a dream of living in a sustainable of the grid floating neighborhoods. and i then with a group of friends, we went to the local authorities, amsterdam be asked, can we build summer in the water? this is our dream and everybody build his own house. like i'm an architect's, it for me, it was a double dream. so it was a dream to live in a group of friends and her in our own unique shades of projects, but also took design within the project. our own house, the neighbourhood is now home to over 140 people and generates a significantly lower carbon footprint. than conventional housing, we have like electricity panels on top. we have like a smart grid system. wherever you have everything altogether,
7:37 pm
we collect the electricity and we do fight it for every households. we have eating panels for heating the water. it's also done by the song, and we are recollect nutrition. so out of the loop and p, we. so we have a black water system that's all our black. what goes into a bio gas station, fac, at the field experiment headed by tiered boma. the team is now taking the opportunity during low tide to set up a tank for testing the weight machine. the walls need to be firmly anchored record due to the enormous forces. the simulator will be subjected to by the tides. also f o, a flex with and with high tide do in
7:38 pm
just a couple of hours. there's no time to lose. so again, with the water arrives quietly but steadily on the moby wave, t managed to get set up in time. they've also attached sensors to the test tank which are connected with their computer, enabling them to gather data for and in higher weak it's now time to turn on the machine. the simulated waves in the test tank will provide the researchers with insights into the impact of the waves on the
7:39 pm
court grass. when you don't want to use a so much for coastal defense, you also need to know how far they can grow. and i, well, one of the mechanisms that they can retreat again is due to play formation. so when your mice gets lotion on the title flats, because it's very for level 3 erosion the salt much, they stable, you can get the height difference. and when this high difference becomes too big, you'll get that lift dental site for a long time, and the cliff erodes backwards. so if you want to know, well, if you want to really be able to use so much for go, so defense years also know exactly are in the which conditions. while these kind of bad processes may happen, sea levels are rising as the climate continues to heat up with temperatures already a full degree celsius higher than in the pre industrial era. a further increase of 2 or 3 degrees would see extreme weather conditions becoming increasingly fierce
7:40 pm
and frequent a potential problem, even for the world's leading sci defense system. i think that it's delta is one of the best defend the delta in the world. so if we talk about today and the coming 21st year says no problem, but given the long term and well, a strategies of adjusting the country to keep it safe from the long term. we're now at the states that we need to learn how to defend, that goes from a, let's say, well, a 2050 to 2100. if we will wait till then to do this kind of re shirts. well then there is time left to adjust the system because we looked at the nature based, defends her, and creating a margin front of the dye to help defend the dike. this will take time because the plants have to trip the sediment and that has to grow with the sea level. and
7:41 pm
that's, that's a slow process. so you have to start early enough with the knowledge, the phillips. mm. ah ah, what people have to say matters to us. mm. that's why we listen to their stories reporter every weekend on d w. hey guys, it's evelyn sharma. welcome to my podcast, love the matter that i and by celebrities influences and experts to talk about all playing loved effect from day to day. nothing less because all these
