we may think our water supplies will last forever. but they won't. when the rain stopped snowing starts march 20th on w. c. hello everybody and a welcome to the latest edition of eco africa i am sundra trina video coming to you from kampala here in uganda it is nice to have you with us and of course today we'll have a lot of new reports of all the different things people are doing to talk about environmental issues and we've me of course is michael presenter nia to pay sandra

it's good to see you again my name is now outside and thanks for tuning in today's program will take us on a whirlwind tour of our views of all continents africa and hero of the shed some light on the environmental threats we face with ugandan eco activists been next on the cards in the wake of a troubling visit to the world economic forum. we go to germany's cups oberlin aware we searchers have developed more plant based cement. now we go to kenya where fast growing type of grass could help farmers and the price. be. when my billing is done then but it's a negative winter don't want to depend more on living things and my she was looking forward to hearing a lot of other young playing make up to be used and just ended up on the continent and going to be about to race on the roof isn't a ship going up a 100 fold i'm not plentiful somebody's gonna leave on a young wife dumping on

a press conference in st john's just to get called town of a news agency local will be you may also see it a place i'll apologize in the meantime but up because of climate activists feel the need to even come on to all the way to voice of i'm being embraced from the climate debate not going to come back home in uganda and it off because when by to visit her. oh. so. it was a moment of joy with such events. when she discovered that i was the only for. she had been cropped out of the published group photo with other climate change activists the incident went viral in an online press conference. in the media. other activists joined in solidarity including learning new from south africa and gratitude back from sweden you're focusing on tried activism

from different corners of you know the western countries but what you're doing wrong is try as much as possible to says out and raise the voices from the global south it makes us feel like they activism and disasters in africa wouldn't be selling care for you. vanessa mccarthy lives in uganda she got involved in climate activism in december 2018 after her country was hit by unusually high temperatures the incident during her visit to the world economy forum in switzerland has not deflated her ambition or commitment. what's happened turned out to be a positive thing because of how we responded to aids as activists from africa and it has our work and most choose to stand up and rise up and demand for action as well as our work in media and the part about the dangers of climate change.

she's also taken hire activism into the classroom at this school in central uganda us she wants to inspire the next generation to get passionate about the environment . animals currently live here to protect the trees. i believe that every kid deserves an opportunity to be in such a class to clearly understand the importance of the things that they see in their environment these kids understand they clearly knew the importance of this tree but if you come into that trust and teach them and remain there that gives them a lot and our way out of the destruction that goes as that goes on in their environment and pushes them to conserve and now she's ready to take her activism to the next level she's preparing a proposal for the ugandan parliament how the goal is to get climate change

a question introduced in the ugandan schools i wish i had known about climate change at an early age i believe that my impact would have been bigger than it is right now that's why i believe that it is important for the president and the ministry of education to you to include climate change as part of the curriculum in different schools the determined dr this also wants to see schools using community energy with support from her family and donors in europe she is now supplying cream cooking stove to help schools reduce their consumption of food. this talks will not only save trees and money but also give the children 1st time the experience of using clean energy it is all part of limey to protect them by the main 2.

only a fraction of south africa's west is the recycling about it 90 percent done took things from the crushed nation into the young into the best one can be a source of disease and beef is well on its triple peak sank and it sounded to young south africans thought he was high time to tackle this problem one of them's a musician the other over cycling x. but i don't likely do what you might think well the 2 men have got together to create their own waste removal system that's it it's good to know. it's 5 o'clock in the morning. as the sun rises the stench of rotting garbage becomes unbearable. these 2 men are determined to do something about all the litter in their community. one solution is said liam

because most of the things that you find here are a 2nd impulse saw saw 60 percent of feet can be repaired to it to introduce a new bongani p.d. worked as a musician and top on morty and he worked in waste management seeing the garbage piling up they both quit their jobs and started the initiative valid green like many villages in south africa can't afford waste collection so there's letter everywhere in the valley green team go from house to house to collect plastic glass bottles and paper then they sort it all. most people in my car used to burn that waste so it wasn't easy to convince them to change their ways and keep things that can be recycled. if it's only really all the way to seriously was giving me a deep including say clean water it sells so when you tell the board to be

recycling for them it's the and us they need easier than killing a youth of i am not go about to say. but to also started what they call the eco hero program to engage with young people about environmental issues once a week they go to the local primary school to make music and dance with the students. participation is voluntary but it's fun to join em and that motivates the kids to become eco heroes. here today i've shown you in love with music and but now. incremented with all these things that i have a new global warming crowd the forest there is in the air pollution over the rivers and pollution of our oceans so you know what why not use my music and the little skills that they have and of course. some guys who have studied the

environment and so what are we combine the 2 most need to create something that is unique and beautiful here motor jani also trains the local soccer team another opportunity to motivate young people to take part in clean up campaigns and teach their parents how to separate their trash. valid green also helps people in the village set up compost heaps to make use of organic waste residents are grateful for all these activities and that makes them more inclined to take an active part in recycling what evil have learned. it's a great initiative it helps the children after school in these crucial 3 or 4 hours when they would otherwise just sit around. with all these projects in the community they can go to find a green i'm bongani entire bangle teach them how to take care of the environment or they can do other things that will keep them busy on the school. day but in the

valley green team take what they collect to a recycling station a major challenge for their business venture is transportation to recycling station pays about 80 euros for a load half the sum goes to pay the owner of the truck so period just $300.00 euros a month in total. he says the solution is to grow the business and gauge a large group of waste collectors who will sell them the things they find. put it in as a pipe it's until they come to oz this is what it's like or worse then you. these become part needs. by inducing to say the words so do more volume we have there more when i see one trust post and leave it. for now p.d. and marty i need a saving up to buy a professional weighing scale and eventually

a truck there and. then they plan to employ dozens more waste collectors. to make and keep my cow a clean place to live. an ounce of this week's doing your bit it's hard to imagine on infrastructure projects anywhere in the world doesn't use concrete well producing cement for the concrete produces a lot of c o 2 emissions well a group of german scientists and the african partners in nigeria want to make a difference they want to make concrete production more sustainable they've made on all standing discovery take a look at this. africa's building sector is booming the continent uses as much concrete for construction as europe does but making the cement that binds it produces

a lot of carbon dioxide up to 10 percent of the world's c o 2 emissions. scientists from germany and nigeria are studying alternatives there are experimenting with remains of local plants such as kosov appeals that have been incinerated at certain temperatures. and are from the ash that we collect we develop cement like products they could be used in place of cement binder sold at local markets that would reduce the c o 2 footprint. from. ash from rice hulls and other plant remnants are also showing promising results using plant based cement is an environmentally friendly alternative. not only can an endless supply of organic waste be put to good use the sustainable eco concrete is also much cheaper to produce. it may even be more stable and durable than conventional concrete.

the scientists hope to see the 1st building made from kosov a concrete constructed as early as next year on the university campus. and how about you if you're also doing your bit tell us about it visit our website or send us a tweet. past rag doing your bit. we share your stories. reading nigeria is a big issue. 200000000 people says it's likely gotten abouta keep growing but can the environment really handle all this massive growth it may seem like an impossible task but our nomination close to showing the right way by taking small steps they are teaching the farmers how to grow organic food and how to take care

of nature one patch at a time. we have to think about all these old. organisms all this things that i live in that still use interest that's. themselves. training in organic farming has become one man's main job he likes to teach out in the field and. he's. like give us chemical to do this from and you see where and comes it was she says it in delta the river goes down to pollute the river. instead he courage is the use of organic fertilizer. and they should. then very mentalist shows the farmers how to mix and apply it correctly his organic fertilizer is made from the name tree and other pond extracts. now we've talked about climate change on the system that has been.

been. so wants to start up on their own aspect of the cultural tool caution that. in trying to 12 he founded the non-governmental organization farm awareness which advocates farming methods the don't harm the environment. the farmers also benefit from the training because using chemical fertilizers degrades the soil over time. unlike those in the conventional method of chemical fertilizers alchemy we call. the natural metals of farming using the environment that use in things around us to form inputs to form fertiliser rather than here and they go to meet the farmers in different communities like here in with. the ngo supports farmers on creating cooperative

because they provide training courses so since 2012 they're trained around 9000 farmers. oh well that's our with thoughts that are good at it but most of us we get more done as if it's a good life i mean that's what it is welcoming to create that when most of us so long there actually is most of all we improve on our family system we have to farm awareness also sells the organic fertilizer which is more affordable for the small scale farmers they need less of the liquid than chemical fertilizer and can buy it from the organization and subsidized rate of about 7 year olds a little. legs under our hands started organic farming 2 years ago after training with farm awareness the season he's mainly planting the summer using organic fertilizer. he didn't make clothes the club into but he's already watch. so we made

a 3 hour flight give me the results. the engineer would like to sell its fertilizer to nationally but it wouldn't sound as an organic product because nigeria has no organic certification system so the group is still facing challenges to friends itself. we all know that mustn't wants is a plastic waste and up in our cities luckily more and more people are coming forward with their own unique solutions to addressing the problem. you're very right near to these young passionate sailors from germany and the netherlands felt worried about the plastic invasion and came up with a very innovative idea of intercepting the trash before it is washed away a seat and now this idea is being used in what always take a look. all kinds of debris swimming in this canal in amsterdam ends up in this catchment cage. a crew from the water company rotter net comes by

regularly to empty it every week about a 1000 kilograms of stuff accumulates half of it plastic. this is how it works and there is pumped into a tube lay diagonally across the bed of the canal and escapes through holes in the tube the bubbles bring the waste to the surface the waste is then directed with the help of the current into the receptacle near the bank keeping it out of the north sea. boats and fish can pass through the bubble barrier be extra oxygen is also good for the water. the great barrier was devised by an amsterdam startup of the same name yeah right on at this point the great little barrier is responsible for the maintenance of the whole installation but that it is going to start doing research so they will start research on how much less stick is being collected and also do research on. how easy it is to be emptied the water company has crews and

a fleet of boats that go around and pull trash out of the city's waterways last year that included more than 40000 kilograms of plastic the hope is that bottle barriers will make the job easier and more effective. that's what this test installation in operation since november should determine. the inventors spent years developing the bubble barrier. there were various challenges such as how to position the tube and resulting screen of bubbles so as to direct traffic to a collecting point and how to make best use of currents. the diagonal path is key. for people set up the company they now have a staff of 10. there's been a lot of resonance the technology is not particularly complex or expensive and it

should prove to be very scalable philip horne is one of the inventors of the system and he's continuing to develop it he's currently working on improving the catchment part of the process. micro plastics are a serious problem worldwide and jeopardize the food chain none the less offshore it isn't the european union for example and yet obliged to clean their waterways of plastic despite the health risks. michael classics because that's a more direct threat to our health that's something when we start to wake up if it's already hurting the environment is usually not enough. but there is still the bad chair around to to get plastic out of the water so that stephanie. challenge fires as as. plastic trash is a global plague that bubble barriers could help combat the team see a lot of potential for expansion. move towards europe within this years and 2020

but also move towards asia once you have a solidified partnership with parties in asia they hope to set up the 1st the bubble barrier in asia by 2023. what are smart solution for plastic pollution here is another great idea this one from kenya right next door often times people graze cattle in local woodlands which can have a negative impact the crowd rational more nutrient rich napi a grass could help ease the pressure of the forests as well as boosting dairy yields on cutting greenhouse gas emissions a win win situation. green testi healthy and pest resistant mapua grass. the hills around kenya's mouth forest offer ideal conditions for these highly nutritious plants which can grow several beaters

told. but the local farmers prefer to graze their cows on wild grassland. kenya has 2000000 small scale dairy farmers with herds of 10 cows or less. all together that's a huge number of animals emitting a considerable amount of methane gas well they just in their food. and farmers are still cutting down forests to gain grazing land for their cattle the biggest problems we're having now about climate change is land use change and land use changes where you are converting forests that are actually talks of carbon and this couple when it is released into the atmosphere actually needs to claim a change so when you cut down forests. to change it into a crop plan or a 4 grassland for livestock then you are releasing a lot of carbon into the atmosphere which leads to climate change. together with 2

european universities the center for international forestry research has conducted a study in kenya to find an alternative that could benefit both the farmers and the environment they can. pair of wild grasses forest grazing and silent 4 da led from locally grown maize there is such as investigated how the cows diet affects the amount of meth and they him eat while keeping a close check to on the animal's health and productivity. glass is one that if you can use very good quality. then it is a very good supplement that. they just a bill to the animals. produced a big boost the next task for the researchers was to convince small scale farmers to change their habits by spelling out all the advantages of the nappy grass they succeeded even though many farmers still want to let their cattle graze on not here

fields they are at least prepared to give them the and for. school in the old days we used to graze our lives still in the forests and on. me. now we feed them on the cuts not the grass and the productivities has improved. but . i can support my family as well as my neighbors. with. the cows now provide about 50 percent more milk than before and the hardys also healthy overall. it's getting so old. then these are decided they saw some. tests takes most you get them from the grass it's very hard to fade the.

map your grass has the shop edged leaves and secrets a slimy substance to try to pass when they land and keep them. healthier cows mean higher revenues and winning equation for the farmers and one with benefits for the environment too had speeding or not produced to want to have percent less greenhouse gases. another reminder that looking after the environment always pays off sadly for you that's all we had for you today but thank you for joining us so long for me from kampala goodbye until next time by nearer to. why for now sandra was the pleasure of co-hosting the show with you i know it's a way signing off from lagos nigeria see you again next week.

to. the for. good shape. what effect of climate change have on our health for me is the g.p.s. it's a very important. key to the future and one of more i see. the whole body is. 30 minutes. old.

how's your view of the world. where i come from that all is that glitters is gold it's just like this chinese food doesn't matter where i am always reminds me of home after decades of living in germany chinese food is one of the things i miss the most but that taking a step back i sees things i need to look differently now. plentiful it's a process not a correlation that exists as a part of the laws haven't been implemented in china that's we've not had a chance of people wondering if they're going to save lives but if you can have our lives to learn from all that is this is a job a job that of the my how i see it i don't this is why i love my job because i tried

to do it exactly the hour a day by name of the uninsured and i was added up to. 2 this region any it was full of surprises slow to move the ball out. to some simpson wanting to be in the footsteps of the great britain india and northern most town to please strict. law. played. 3 times wanted to still very much alive to be a challenge to specialists in germany. recognizing where exactly. was fun and the last hours. culture history of. d.w. travel extremely worth a visit. to. the
