hello, yes, little surprised. hi. i was shopping and i am ready to dive into the hands of the gentleman who to us. you have you have a one to talk to me before you go to the spas. i'm the i'm expected sides of the roads. 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 chris, a lens. joining you from league goes nigeria. what works best is often a combination of traditional wisdom mixed with cutting h innovations with gold both on stays. so i m, sandra holmes, the tween over,

you write it in complex, you going to it is great to have you with us. here is what we have. i mean that indigenous bonds 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 started right here in uganda. oh, well me, population goes hunting hunt with a blooming construction sick to and that can take it stored on the environment engine is looking for or the tennessee used to climate demanding materials. and they have come up with some promising ideas. the districts dr. pressed and did not try it in a kiln. they 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 steven duco believe a switch to a tentative construction materials is long overdue. when you drive through many forest, then the 40, so don't feel that documents 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 out of segment bill and the simon trying to fracturing produces a lot of the youtube. but the into looking brakes are easy to assemble. full, they need less, i meant them breaking the ones to the book that comes out is the intel. okay. 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 or vegetation that would have been cut down to,

to know that to produce a break or to build a house. in uganda, most houses a student made out of q and fi, it breaks, which mostly use firewood. there are 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 and 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 as 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 to factoring 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 on a new one hand is that she works for echo concrete, a company that's mix simmons using of full kind of cash. traditional segment you've made out of limestone and firing it meets massive amounts of c, u 2. when you hit one kilogram of lamps, then your image of bullets or 44 percent of it is going dukes. i do under 1855. so for one time, when you put in all of the production emissions, you find that for 110, you may download 100 kilogram to come by next i to the about how for the it's the engineer has been working with students at martinez a unit above the t 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 uses 5 times less energy than limestone. base 7th result is what's called jew pulled him up segment the test tub shows that this product could capt emissions by 80 percent compared to ports and then 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 these materials up prevent to be better then brooklyn cement the engineer on the architect, share a common goal to help make uganda is construction industry more sustainable then missouri to be broken 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's studied in the building profession

architecture. and then we've made colleagues in engineering, we are responsible for many of the design. so that 1st it starts with a that'd be commendations a bit or that specifications or give to our clients. was steven zucker has been using his bricks for several years. may i have you on a new i have is a, is a starting pilot production and hope to soon get the green light from looking forward to it's amazing how just one good idea can have such a positive effect on people's lives. us and next for pull 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?

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 this swedish company model has to turn to a traditional construction material. quote, if somebody says it a more davidson built out a 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 mont, beyond the skies, but limit man, because you're going to build up to 214 meters. the 1st commercial turbine has already been erected in scott on 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 of

lead muscle cluing. 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 a 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. would have more to work right together, so we protect out house with the coach on the outside so they can withstand the climate and see or they can move in 2021. the damage company, best us invested in the might be on scarred 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 the you mind. for our 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, what

a 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 life and oxygen. scientists footage shows how the bottom of the fuel it has become nearly devoid of life in waters that once but 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 on the 2 point. oh, excuse me. no, no, no, no. the nicholas ends mine denmark's farm is to blame. the small country with just under $6000000.00 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 c christian medicines finalize only a few kilometers from the field. he says he has already cut the use of nitrates to

the bare minimum. he uses 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 fertilizes, these plans are already only surviving on what is left in the ground. the mads, she has the christianson is aware of the problem. as a nature manager, these are the seeing a project and restoring the ecosystem invite yes, your, you know, is the odd facts and numbers. at this point, we know for

a fact that the 80 percent of the nutrients emitted to why the fuel 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 gross to explode. the balloon covers everything in the field. even killing that you gross due to like the probation that same you grass 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 new 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 more light to penetrate deeper 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. you fuel. 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 to begin, let's see, has become disrupted. lots of mucous inside these 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.

then cut 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 baltic seas entire coast. that is certainly a warring 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. it 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. a large proportion of fresh produce wells before we can be sold. it's something that's frustrated. ramos out loud. okay, ever since you opened up business, 13 years ago the my thought is that we try to sell new produce before the end of the next day when it's very sunny model because our rates. so it's going to quickly just say no. the price drops when it's no longer fresh, but i'm before i sold these for almost 10000 now,

but now i have to sell them for less than 6000 there. once they've spoiled, we have to to them out. it's a waste news money. at the same time, many people, the layouts haven't got enough to eat. mack of somebody that is a found the biggest food bank that distributes food to those who need it. he says food waste is increasing a hybrid and you don't wish to about water. i need to make, you know, grams of foot by year. more than 40 percent of the food we produce is lost across the entire agriculture of value. the value of food that goes to waste, right? um, on one of the men julia is more then several and also about time i don't have that capacity to stuff and for a long um, fuel stand for future say a lot of food that ends up in launch 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 invest that we intend to extend the shift life of this for this one to, to about 20 to one days. so this courtroom has been helping a lot to solve the problem. of course, how this little face on food with gold hops 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 store trait 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 the keys y c, n k i n one. now, before we used to buy small quantities, the just a nice to and i sure 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 us for, for the toner and sort of asking them to come back the next day. and the guy portal is that good you can cuz you can see it unless i added the guy to me. if that was he would be looking for any trade is. however, 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 hill bridge and women are re discovering in fiji. those plans start to grow wild, which will once unimportant part of the process. those diets in terms of climate change. these have many benefits. the women of scale,

that plucking the leaves off the twisted branches of good trees as a village of dun boot, uh they are in demand. the women can have is 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've had 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 the, for a foreigner, all my relatives took me to so harass, so helpful in the neighborhood and told me that the by i do have thoughts, does that dates. so i started selling these to them is because there's 2 plots from left to me. so what would anyone by i do it for me it's but then to what is drawing to me, you know, for, to women do we to get to harvested market native? well, plants came from joseph, got to be, he grew up in a j and a 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 leaves fruits and seats. and they've learned to appreciate them. new years ago, we had the special ed training program and we were showing them different recipes, different ways of preparing homes up and making a nice, vicious,

nice news from it. and that's really is 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, you know, 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 wants it. so how does that help food says with activities in the region says 2014 and these days works with 1500 small farm is 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 are now sold around these. you have some of them also exported a dot net by as 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 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 good 3 quotes 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 why i was, i would. why do we have taught them a lot of things such as how to cancer with souls made from home to jews, which did in new tons of power rich? which did you didn't know either on to, to bayport's biscuits and them basically would set them a lot of recipes, homeless available. why do i, can i'm go what i'm 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 reselling them using a direct feeding method side as to how food successfully we planted 160 local varieties in this way. the farmer's fathered suit, share the communion of dog. oh, but the 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 w p. 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.

joseph gobby also teaches at the university of linda. he works together with dr. i do not do. the topic of local wild fence is also on his curriculum and it's already been sending students to train with enterprise since 2018. they do ment decide as a how to read the sawhorse. i have food side has become a training ground for our students and was they to deal? it's where they go to learn about the plans that are most often found in the carriage and semi arid zones. here in the shared is one, see me. i see one is yeah. after 10 years and the vendor region, gabby's project is flourishing. many spoke to the farming families on the x that's on 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 go 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 with blonde and load again this week. we hope you've enjoyed the show as much as we did. i m sandra holmes, that we never knew signing of from complex right to you got the a and i of chris 11. see an idea. thanks so much for joining us. and don't forget to head to equal oper go online for more insight to stories and drop off a line at ego dw dot com. so you again, next week the
