save the date for the d. w. global media forum 2023 in bonn, germany and increasingly fragmented world with a growing number of voices, digitally amplified. we see where this clutter can lead what we really need, overcoming divisions into vision for tomorrow's journalism. save the date and join us for this discussion and the 16th edition of d, w. c. global media forum researcher and mace long and was among the authors of the u. n's. 2021 climate change report. it's projections for sea level changes were a wake up call for governments and scientists. i guess that was my real realization like, oh wow. this is a very yeah, this is really bad slogan, is

a climatology to works at the royal netherlands institute for see research sodas tiered boma and expert in the dynamics of coastal ecosystems. who's devised a wave simulator to help improve the country's c defenses. adjusting the country to keep it safe on the long term. we are now at the states, and we need to learn how to defend the coast. their colleague, clos timmons is also committed to stemming rising sea levels. and when it comes to reducing our carbon footprint, see wheat, he says could be a game changer i ah

mm hm. coastal ecologist, teared boma specializes in reinforcing levies or dikes and says there are still valuable lessons to be learned today from the north sea flood of 1953. the devastation back then was more limited in places covered with the marsh grass. around it effectively absorbs energy from incoming waves and dampens their impact, making court grass of acute interest to researchers. no one is she a picture of it? here you have to she area. and this is the polar which is now being flawless. and what you can see here is the green area shelf, marsh, and here there was no salt, much in front of the dike. 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 and both frequency and intensity. thinking if you live in a low lane, can feel like the netherlands, you will never be able to live there without dikes or bits. with sea level rise 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 for to keep our float safety. stand this to keep those of it's 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 it's we have to make smart use of nature and combination with engineering. and you can really see that 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 incision in how we cope with flood safety. and so there is a growing willingness to think about alternative solutions in which nature placed an important role boma uses this wave machine to illustrate the principle to doctoral researchers. course of market levies without court grass erode pastor shopping because she well, i was trained as an ecologist, but i always share berg as a kit already on motorcycles and all kinds of technical issues. and so i like to play with and very happy at the point when we were designing these that we had 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, so important, any quality. so what you, she, she gets the big wave hitting there, and then the wave goes back and reflects of several times. and by that asian metric movement of the way, federal, we get to really realistic, irregular ways. and that's the magic in this book. so the scientists firmly believes that court grass is a viable solution for coastal protection. oh, i believe the challenge now is how to plant the grass in mud flats without it being washed away by the north sea tides. it may be hard to mention that now it's completely dry and the water is far away. bitter and free. our shirt from now it will be

completely closed again and 3 hours before it will 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 this will help us to widen the marsh and thereby exactly. yeah. so with a 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 our dice. 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 he 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. while on the contrary, now, this is really the basis of the food chain. so, so are organisms like this day, you sold our lights, c, u 2 and foreign bio mass. so it's, it's 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 most efficient way to produce food. these plants stay growing salt water. there's plenty of sold. what are they out? a shortage of fresh water in many areas. and hence about these he said this bio

mass has many characteristic to make for a suitable also to you had this food for humans 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 seaweed forest in the ocean and the with global warming, some of them just disappeared. so i want to know the reason that 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 institute for see 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, 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 dry parts,

ands, or where to dry parts. we make smoke pellets, which you can use as a fertilizer in gardens, for example, and the urine. yeah, we process it actually, and then we may clean water off. it's it's, it's quite high tech. it's new. it's also our invention and had to do with like that. and then we can put it back into the harbor. all the water from the roof is collected and as if going hit with those pipes here is going down. it goes to our feller they have we, we have a system which cleans actually the ring. water shall, would get some dust and other parts out. and then from there we pump it up again, and we pump it today to, to water reservoirs 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 ground water farmer of them, fine horses finds himself fighting a battle on multiple fronts. over the mac, a method drove fish along. we get drowned periods of,

of the last 5 years for were dry. i was also mock 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 for the 8th of all. and that means having to pump it out. well, thought of it, of her food with, with the resulting deficit in farm production, says clos timmons could be partly compensated by a whole new kind of sci fi. who has the back in the lab at the see research institute. he and a doctoral research are looking at ways of extracting proteins from seaweed. animal class. the aim is to create supplements and other food products. if you want to extract larger quantities, then you need to buy 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 bio ma 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 seaweed is still in its infancy. we can actually bring those together in specific crosses, so they're males and females, and we can cross those. and then we can actually cross, for instance, material from hair and say, lawns, and with material from norway to see what effect it has on and on the, on the how the copy she looks like. so maybe they grow way bigger. so a farmer has better yields,

and maybe they have higher protein contains or higher. sure. content, for instance, for the bio ethanol industry. so, and she want to breed force. yeah. specific industry uses the scientists want to increase the harvests of marine farmers like yost about hers . while the c 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 see week to the dutch food industry. right now. it says there is no she read in the house is behind is old kind of old. our bio mass is growing on the length. so we need to clean them because the lines become too heavy and they take away all the lies and all the nucleus of the

syrian i think when people began farming and as of years ago with thousands of years ago, they also run into things that they find out and, and optimize over time. we're not there yet. so we need to know, we need to invent the little things. we're still, every one is walking and see way the still kind of buying. yeah. there's a lot of things possible with seaweed for human and animal health to regenerate soils to uh, make materials like plastic. so there's a lot of applications with c we. now what we see over the last years is that the demand for c read is growing enormously because see, we doesn't need lans, it doesn't, it fertilizes and it doesn't need fresh water. she can see it grows just outside

and need sunlight and need c o 2. and it needs said the marine nutrients that are in the water. that's whole. so to see if there's any, any other resource. well this is the slow process ruby don't all discourse 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 for a healthy salad number. i hope a one year every kitchen, every store i fresh see read ah, see reads. her father is very good for ever everybody special. this one, we're,

this is we have a retreat though, so we call it in riots and another thing temperature stays is like an beacon. no omelet. it bacon. widowed bacon is a future food with seaweed can be added to everything from gloucester and bread to burgers. ankles, all another aim of the shaft, turned food innovator is to unlock participants. creative potential, fully thought new, fully them. what is owner even with ha ha ha ha ha ha ha! teared boma has made a trip down to the see for 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 ecologists together with engineers. and is one of a kind no, never honda tailored thing. you know. the mobile machine has its own name, the moby ways with the other for them. and you can get out of the way that we get out of the way. i'm. if you think about safety, then also camera, mana began. behold, go, shoot aside for say, also told okay, what went wrong there, but i'm happy you're sending behind. it's helping to get off the wheel. the problem was not the wave machine itself but the winch,

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, as in the days to come. it will help them to study the delicacy plants, properties. lou, 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, 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 on 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 though, 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, hist has analyzed 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 our coasts . and on top of that, a sea level rise is not the same everywhere. this big regional differences. so if we, it's $25.00 meet centimeters on the global average. there's around the equator, it's typically higher than $25.00 centimeter day. might get 30 centimeters already . and then if you're in a country like bangladesh, which is really low, 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, 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 if he did the projections of climate scientists. this little neighborhood in amsterdam was born in 2008 years before the u ends. intergovernmental 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 and a typical, densely populated and concrete clad urban neighbourhood. 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 i in our own e j to projects, but also to design within the projects our own house. the neighborhood 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 where you have everything altogether. we collect the electricity and we do fight it for every household. we have heating panels for heating the water. it's also done by the sun, and we are recollect nutrition. so out of the loop and p, we. so we have

a black water system. as all our black water goes into a bio gas station, fac, at the field experiment headed by teared bomb, off 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 or due to the enormous forces. the simulator will be subjected to by the tides. also f o. a next do a the with and with high tide do in just a couple of hours, there is 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 an higher week. 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 court grass. when you don't want to use a so much for goes to the fence, 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 emotion on the title flats, because it's very vulnerable to erosion, the salt much, they stable, you can get the height difference. i mean, this high difference becomes too big. you'll get that lift, that's will say that 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 goes with the fence, you also know exactly which collisions well, these kind of bet processes may happen. see levels are rising as the climate continues to heat up with temperatures already of 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 and frequent a potential problem even for the world's leading see 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 at 2030 years, there's no problem with gifts and the long term as well. strategies of adjusting the country to keep it safe on the long term. we're now at the states that we need to learn how to defend our coast from a, let's say, well, her 2050 to 2100. if we will to wait till then to do this kind of research. well then there is no time left to adjust the system because we look at the nature based defense her and creating a marsh in front of a dye to help defend a dike that will take time because the plants have to trap the sediment and that has to grow with the sheila fall and that's, that's a slow process show. you have to start early enough with the knowledge phillips with
