to hi, caesar was every single connection mapped out shows that you can disagree odyssey be on the board is what makes things 2 ways a mapped out, navigating a changing world. now on youtube, the arrows that's those had some pretty good ideas and some of them can even help improve people's lives today. welcome to eco africa. i'm crystal lambs joining you from lee goes. nigeria, what works best is often a combination of traditional wisdom mixed with cutting h innovations with gold both on stays. sure. i m sandra holmes,

the tween over you right to come play you gun to it is great to have you with us. here is what we have. i mean that indigenous lines provide women in united with food and income. why more wind turbines might soon be made of routes and not still? n y c shuck diagnosed to the cost of denmark, but we installed right here in uganda. oh, well me, population goals, hunt and hunt with a blooming construction sick to and that can take it stored on the environment. engineer is looking for alternatives to climate demanding materials. and they have come up with some promising ideas districts dr. pressed and multiply it in the killed, the middle sand and up until segment and

a lot of muscle power and no votes. since there's no killed, you're going to actually take stephen duco believe a switch to alternative construction materials is long overdue. when you drive through many forest, then the 40, so don't feel that darkness surrounding you. so the problem is that we need to stop fighting bricks to make, to make our house is about a quarter of each week is made us will segment bill and the simon trying to fracturing produces a lot of youtube. but the into looking brakes are easy to assemble, full, they need less them into the banking. the ones to the book that comes out is the intel ok. it looks at the top at the sides and the bottom. so by that's we, as where we reduce the amount of the same inches to deal with that structure. and that's where we are reducing the emissions by addressing the segment and the, the amount of cheese, that's all vegetation that would have been cut down to,

to know that to produce a break or to build the house. in uganda. most house is a student made out of q and fi. it breaks, which mostly use firewood, thousands of small brick making businesses like these throughout the country. and the ongoing housing shortage means the brakes are in high demand using pressed brakes and states could help save a lot of plywood. the homes are still look the same as for the home owners. they also offer other benefits constructing. we've, instead of looking groups enabled us to have our buildings in less than or 2 months, it's 15 our budget and then we also save because of the money that would the views to transport, to my, to yours. the construction industry is a major climate tequila segment. one is lecturing accounts for some 8 percent of

global coupling emissions. that's why engineers us cutting ways to reduce or eliminate segment in brick making, including my view. and what i have is that she works for echo concrete, a company that's mix simmons using of full kind of ash, traditional segment that you've made out of limestone and firing it meets massive amounts of c o 2. when you hit one kilogram of lamps, then you image a bo, it's, or 44 percent of it is comp windex. i do under 1855. so for one time, when you're within oh, as a production emissions, you find that for one time, you're in meet downloads and 100 kilograms to come by next i did about half of the it's the engineer has been working with students at market as a university income pilot on the new process. volcanic ash is plentiful in uganda,

just like an ordinary segment. the recipe calls for sodium hydroxide, but the mixture doesn't needs to be heated. so the process use is 5 times less energy than limestone. base 7th result is what's called jew pulled him up segment that test tub shows that this product could capt emissions by 80 percent compared to portman segment which is used around the world. we've been using it and looks building books. and those are done with the absorption, this and this materials up prevent to be better then we're clients and meant the engineer and the architect share. a common goal to help make uganda is construction industry more sustainable. the missouri took the book into our way towards the it's how they get to work. but to engineers is different actually have this test to innovate and reduce that come windows and emissions as someone who started in the

building profession architecture. and then we made colleagues in engineering, we're responsible for many of the design. so that 1st it's tough with us. that'd be commendations or big or the specifications or give to our clients. was steven zucker has been using his bricks for several years. my view on a new i have is a, is starting pilot production and hope to soon get the green light from local authority to it's amazing how just one good idea. it can have such a positive effect on people's lives. and next report to stay with the elements and go from water to wind power. we all know wind turbines are great source of clean energy. yes, they are, but the actual construction of the still turbines can use a lot of couple in the oxide that gold, innovative, and sweet and thinking. what about making them from a different material?

the wind power is environmentally friendly, but building the towers isn't the materials have a big carbon footprint, especially when that towers are made of steel as nearly all of them are nowadays. that's why the swedish company moxy has to turn to a traditional construction material. what is the motive? it's built out of full modules which are assembled into a tube section to restock them on top of each other. and in the end, you get a total tower for month fee on the sky limit. man, before you're going to build up to 214 meters. the 1st commercial turbine is already been erected in scott on the northeast of golf and burke. it's not quite that tall yet, just 105 meters. the towers made of layered, laminated wood vets bent into shape. as in the muscle doing what together is much

stronger than bolting or screwing. it must be on says the what is fine sustainably . the 1st commercial tower is equipped with the 2 megawatt turbine and like steel wood can also with the stand the harsh conditions of offshore operation in the water and still don't go together with them more to work. great. together we protect out house with the code to you on the outside so they can withstand the climate and see or they can move. in 2021. the danish company invest us invested in the mark beyond start up. they also built the turbine in scott off, if the innovative would turbine towers catch on. it could help make wind power even greener solutions like that can really low a you mind. for a next report, we stay in contact with you and to head to an island what a body in denmark, the looks beautiful, but in fact has almost no marine life left to need. that is because the water is in

very poor health. the, the baltic sea, with its stunning nature, is one of northern us most popular travel destinations. and the coastline along by the field is one of denmark's most expensive residential areas. but it's superficial. beauty is deceptive. he's weekly fishing trips continued to show fish las amigos in how the feud is slowly dying. below the surface l. d. 's blooming clouding the water and depriving fish and underwater plants. the vital lights and oxygen. scientists footage shows how the bottom of the fuel it has become nearly devoid of life in water. is that one split full of cod flounder and lum fish. it used to be a real fish, as paradise says nicholson. but now there are almost no fish left.

he's been going out to sea for over half a century because then had hoped to continue fishing off to retirement, to supplement his pension. now, taking the boat out is not really worth it anymore. somebody that has a new plan. he makes me both angry and frustrated. nobody is really doing anything special. no it, it seems like those who should be taking action are only trying to shift the blame of the 2 point. oh, excuse me. no, no, no, no, i didn't make a since mine. denmark's farm is to blame. the small country with just under 6000000 inhabitants is home to twice as many cows and pigs. and many farm is used fertilizers on the fields that eventually end up in the sea. fishing on the mountains, finalize only a few kilometers from the fjord. he says he has already cut the use of nitrates to

the bare minimum. he uses a satellite images to monitor which fields need to be fertilized and which can do without. but he thinks it would be impossible take about fertilizer is altogether i think it's a good thing that we have reduce the nitrogen, but i don't think we can get any further. i think we are the lowest limit that we can accept as a from plants need nutrients to grain one grow without them since the pharma and since reducing the use of fertilizers. his plans are already only surviving on what is left in the ground. mads fields christianson is aware of the problem. as a nature manager, he's only saying a project and restoring the ecosystem invite. yes, your, you know, is the hard facts and numbers at this point, we know for

a fact that the 80 percent of the new since emitted to why that's what it comes from funding. we also have 10 percent today from, from the up in waste water. and maybe 10 percent from from fish farming, but that is the range. and that's uh tell us a little bit about where we need to have the nitrate run off regularly closes out the growth to explode. the balloon covers everything in the field. even killing that you gross due to like the probation that same you across is one of the most important elements in the ecosystem along the baltic sea coast. it produces oxygen and provide habitat for smaller fish. that's why christianson and his team from the municipality. i've taken to planting you beds of you grass invited your fuel, but the restoration project is complicated. artificial rapes are being built and muscle fonts, created these blue muscles filter dirty water,

which in turn allows mold light to penetrate data. fuel gross can return and therefore produce oxygen. but when too many nutrients are flushed into the sea again, causing the algae to return, the fragile balance is thrown off and the nature manages concerns not restricted to divide the feud. we have hit this breaking point the, the system has collapsed within the last 56 years. so that's just the beginning. we will see this, this situation is over the baltic. along the coast, the eco system of the inland sea has become disrupted lots of mucous, and so he's little other than crowds in the nets. he puts out in the value fuel of the since they no longer have any natural enemies, they have become a plague. destroying that, you gross eating the muscles and killing the young fish dead cod

makers in hopes that everyone in the region would take more responsibility and act to save his fuel. because the problem, denmark is currently looking to solve is already threatening the boating seas entire coast. that is certainly a watering situation. we all need to take responsibility for the good of a planet and talking of responsibility here in africa it's, we, women will certainly curry and lots of it up to roll. we're still very often the ones who look up to the home and the fun me, including of course, preparing meals and the fresh produce for those meals often come from the markets, which is great. but in the heat to low fee, it's full quickly. luckily though, there is a very cool solution that has the pot to make the problem. i've seen of the past

on the outskirts of lagos, fruits and vegetables, i be going for the more than 15000000 inhabitants of nigeria largest city. there hasn't been room for that within the city limits for a long time. now wrap it up and growth means it takes long got to get produce from the farms to the customers. that means the harvested vegetables have to be delivered quickly as there was a lack of refrigeration facilities across the country. lots proportion of fresh produce wells. the fluid can be sold for that is something that's frustrated. ramos out loud. okay. ever since you opened up business 13 years ago, this is the time that we try to sell you produce before the end of the next day. and when it's very sunny, we call batteries. so each one's politically kinda saying no, the price drops when it's no longer fresh. and i'm before i sold these for almost

10000 now, but now i have to sell them less than 6. so on there. once they've spoiled, we have to, to them out. it's a waste news money. at the same time, many people, the illegals haven't got to enough to eat macro. so the is a found, the biggest food bank that distributes food to those who need it. he says food waste is increasing. i have written down was talking about warner, i need to night, kilograms of foot by year. more than 40 percent of the for the produce is lost across the entire agriculture volume. if i knew a food that goes to waste, right, and one is more then several, and also about time, i don't have that capacity to stuff and for a long fuel stand for future, say a lot of food are into open land, fuel costs, easy, greenhouse gas emissions that affect the climate. there is one solution to the lack of cold storage space. cold tops was developed by my julian starts up financed by

a wide range of international investors. we intend to extend the shift life of this for this form to, to about 20 to one days. so this schedule has been helping a lot to solve the program. of course, have this little face on food with gold hubs now operates in 28 states in nigeria and has over 6000 customers. the walking cold rooms are located next to markets are on farms and i cooled entirely using solar energy. customers like trade copy rooms to pay the equivalent of $0.20 a day for us to crate the vegetables to him. it's worth it now. he can charge higher prices for his produce because it stays fresh for much longer. when i do close to one, when they keys, i see and tie in one, i'm not the full. we used to buy small quantities just enough to that show would sell out the same day. okay? cuz then you wouldn't do that. but now do we have the cold room?

i mean, we've been buying a bulk installed in without any problems at any time that kinda can meet the customer's needs. and by simply setting what the last 4 of the toner and sort of asking them to come back the next day for them is that can you can as you can see it on my side, i thought it did kind of see me if that was the it would be so many trait is how is it cold? storage remains a dream home. the shoes like gold top steel is very limited and there's a numerous demand. some 220000000 people living in nigeria and the population is going faster than almost any other country in africa. we're staying with the topic of food in the next report in many rural communities. and so hilde rate and women are re discovering individuals planned start to grow wild, which will once unimportant parts of the around says those diets in terms of climate change. these have many benefits. the women of scale,

that plucking the leaves off the twisted branches of jacob trees and the village of dun boot, uh they are in demand. the women can harvest the leaves all year round, using them to cook or to sell at the market in the nearby town. those in the and that when i bought it in, before we used to go into the bush to cost would double, could sell to buy food. and then one day i went to sing differ from there. all my relatives took me to so hard, so helpful in the neighborhood and told me that the by i do have foods does that dates. so i started selling these to them because people had to him left to me. so why would anyone by i do a fruits, but then to at this drawing to me, you know, for 2, we mean do we to the idea to have is to knock at native well plants came from joseph. got to be he grew up in the j long been thinking about the benefits of

reviving native trutland trees, such as the wild tons of species. and they used to have hands out. they used to eat tons of it only in times of hardships. so when we started working that with them, we started buying their hands at 1st, they were reluctant, they didn't think we were serious, but they realized that we were actually serious. we were actually buying it. and they got involved in harvesting lots of homes and delivering to us. and they became very happy from the extra income they could make. but we weren't quite satisfied because they were harvesting in order to sell us. but they were still considering it something that they'd rather not eat themselves. now there's thought to, to change their minds as a social enterprise. so how does to help foods raise as a way that's in local communities about native trees that can provide nutritious needs. fruits and seats, and they've learned to appreciate them. years ago we had the special ed training program and we were showing them different recipes, different ways of preparing hands up and making a nice, vicious,

nice news from it. and that really is the struck on. so the year after they said that they had very little homes up to sell us. and the reason they said was, that's well basically, now they were eating the hands of themselves. so instead of selling it to us, they'd rather keep it for their own needs. exactly the result he'd wanted. so herself food says with activities in the region says 2014 and these days works with 1500 small farmers and 80 villages because they supplied. there was fruits and meetings from over 20 local 10 species which are then used to produce oil, jam spices and pastry. 60 products that are sold around these, you know, some of them also exported a net behaviors up until today. many people thought that these, the students are just local stuff and don't have any particular value. they. so those about them because they just grow wild in the bush. but now people have begun

to understand the product. so useful. for example, adult to is it sunday or national hospital prescribe foods for my show, such as hands up storage, which helps diabetics product that you want. so how does that, how foods could 3 close is a popular today instruct uh how i have blue is showing the women what they can do with hundreds of fruit. it has a high protein content. the well that's where i was i would. why do we have taught them a lot of things such as how to cancer with souls made from home for to tooth? which to new tons of power rich, which did he didn't know either on to do bayport biscuits and basically we thought them a lot of recipes is available. why do i, can i'm go what i'm going. joseph got if you learned

a lot for me is no region father. on a gobby was a young man when he immigrated to initiate with his wife. he began collecting seeds from indigenous plants and re sewing them using a direct feeding method side as to how food successfully we planted 160 local varieties. in this way. the farm was followed suit here, the communal toggle of 5 kilometers drums into many of the trees were planted by the farmers themselves. the whole idea of diag sitting is that you can teach it to the farmers, and the farmers can teach each other. and um, and then once you get the at the, what we call the v c. economy established, it will have its own momentum. and i would like to inspire people not only here, but all over the world to use their indigenous perennials.

just of god, the also teaches at the university gives into your works together with dr. i do not do the topic of local while fans is also on his curriculum. and it's already been sending students to train with enterprise, since 2018 durham, and decide as to how to read this a. her, a saw her food site has become a training ground for our students and was the to deal. it's where they go to learn about the plans that are most often found in the arid and semi arid zones here in new jerry's and see me, i need to see when is yet after 10 years of agenda region, gabby's project is flourishing. many small world of farming families and extracts and various local t variety and how to care for them and not passing the insights onto the children. because i see, you know, a child, well what you from a very young age, i might have to understand that it's with the income from these efforts that will

buy them certain items. so she follows you know, full steps. and that's why, from time to time, she feels trees to mean that you still have the regular income. i can feed her family well. she's even being able to build her own house that the small seeds have borne fruit. so there is still a lot of work to be done. well, we blonde and load again this week. we hope you've enjoyed the show as much as we did. i m sandra holmes, that we, nobody is signing of from complex, right to you got to and i am chris 11. see an idea. thanks so much for joining us. and don't forget to head to equal oper go online for more insights and stories and drop off a line at eco dw dot com. see you again. next week. the
