River will all be out of those yeah. I am my god julia its great to have you with us on the show. Its changing and the new report from the un details the deepening crisis its a catastrophe thats not made in africa but its already hits in the continental my colleague community sends us this report from nairobi. Its a widely held belief here in africa that Climate Change is a problem for the rich its also a prize and the fridays for future protests barely gained any traction on the continent just about 10 countries participating in the events that tended to be fairly small the irony of course is that its poor an ordinary africans were most affected by the impact of Climate Change here in kenya had. Says who are running away from a persistent drought having to bring their livestock all of the way uphill just to keep them alive and in nigeria more and more people are being forced into the cities as desertification puts pressure on their land the african governments however say that they are trying and you can see that they are wind and solar farms such as this one sprouting all over the continent but the african governments say that they cant do it alone and they need the rest of the world to hold up their end of the bargain you have mentioned that theres its spreading as average temperatures go up the well doesnt just get hotter droughts and dust storms are also growing more intense our next report. On the edge of the so hot that he genes are creeping closer and closer to the coppertone you know me but some people standing in the way children and teenagers lead the fight this is. Not far away from me on the bank of the river sounder and so forth and the field trip will enable the pupils to understand the phenomenon of desertification but well also see what people can do locally to stop the spread of the desert and to anchor the sander and. The gigantic dune of subtle ray at the gates of the capital niamey the pupils only want one thing to climb on to the dune as quickly as possible. Some of these sand dunes wander up to 20 metres a year depending on the wind their height can reach 30. 00 to 40. 00 metres the pupils are overwhelmed once they get to the top. While its off ive never seen anything like this ive never been here before its so beautiful. Visually but yes it may be beautiful but its a nightmare for humans and animals so you want it you dont want to stand there instead bury your homes you have to try to prevent them from shifting. With sand drift fences for example sonny yuba explains what everyone can do to help stop the shifting of the dunes the students are pensive. After seeing this here im quite troubled. As you had some point the sand could reach the town. That makes me afraid. Theres only sand left here nothing grows here anymore its a real desert. She keeps advancing and reaches the People Living on the river now and itll be all over. The outing had a big effect on the pupils there now motivated over the holidays theyre going to environmental camps where they will set up sandra fences and plant trees anything and everything to stop desertification. Like you just saw him in that report sonny are you is the executive director of young volunteers for the environmentalists sonny welcome to africa now the young people in your project seem surprised at the deserts on the out doorstep how did you realize now how dangerous that is so. What is. The number one. Or. 2 we need. Or want. Again it will most all people. Or end it all in and i understand you have a project this weekend its a lot of festival when the faithful slaughter a sheep so what does not have to do with the desert because we had eyes that all wanted as most important that every year is like more of them or 2000 thomas would loose on the only day of people willing she was so or people in the local for. Them to see to that comes out on the 11th so its too much or weve got all i wanted all signed on things and give us the news of lewd things. And thats why im decided and im bent on getting it will is like. All to celebrate i was there and there was it isnt she and it was it in a ship or moment so thats what i mean quite deep oil or clung to the believe news the consumption would be the 1st thing is a lawyer was or would an indignity in the leg or is not the mission or the illusion so people can awaited me or they have. It and also is. Like i kind of elect ok i can make that if france. Also. Sounds like a very smart i. D. s as i can see if their act of young volunteers for the environment thank you. And there. Sunnys for. Is just one of his if hes involved in another one involves a completely new type of stove that runs on the waste people are using. To the fi the deficit. And Environmental Protection in action. Xenia is learning from master blacksmith eve rahima mana how to build an oven that works without wood all parts must fit together perfectly so that the oven closes tightly and no heat can escape. He brought him a man is building a series he just received an order for 50 ovens from the ngo volunteer how porn on feel through. This oven is a tool in the fight against desertification because its not filled with wood but with rice husks the husks cant be used for anything else not even animals a ton of i dont like but every day tons of rice husks accumulate in the state rice factory its waste with no nutritional value everyone who has an oven can get it here for free to use as fuel sunny yuba visit schools to talk about the ovens importance after all trees and bushes hold the desert sand in place so this is about our behavior we have to change our behavior and our way of using Raw Materials we have to as you said correctly use clean energy and especially use Power Sources that allow us to reduce our use of wood what. The pupils are allowed to test the oven at home for a week. How big my money bossa root tells his family how to use the appliance. I went to. The nothing but. Now we act and it seems easy to use it produces hardly any smoke and you dont need to use wood anymore thats good i want to try the oven out properly. A new oven costs about 15. 00 euros and the in geo also gives credit. And my next guest professor. From the university of hes a study in the environment across south africa. Thanks a lot for your time now your project studies several ecosystems which up mostly dry but not yet basket whats happening that well we study it. Up to northern angola and zambia. And compassing all the different ecosystems and we learned that africa is a. Very diverse so we have to distinguish. Well in short we real desert if you cations a proper sense as its expanding in south africa and the maybe especially during the last 5 years there was a perfect storm of Climate Change and intensified land use. Those affecting each other wife has a nose and as a venice human activities are expanding we see the forest disappearing. Forests. And there are really dramatic changes really calls for action by politicians. Down the river as drying out what concrete effects people live in that. Well again a wide diversity let me take 2 levels in lusaka zambia several times where we experienced up to 48 hours power failure per day there was no electricity in the capital under whose city and the reason was a lack of rainfall and westons mbia and eastern angola many months before and that caused less water and Zambezi River and finally ends a kind of riba dam so that the remaining water it to be used for agriculture irrigation to avoid food problems and no more water was allowed to runs through the generator systems to give electricity so you see there is a cascading effect yassar on nexus being very different areas and more important in the country where people clear forests for charcoal they still believe forests are never ending however from our country relations we would say and 5 to 10 to 20 years the different groups will meet in the middle between 2 roads and then there will be no more forests this very dramatic this will have to a metric Economic Impact and again must set up management of these ecosystems. Dramatic problems not of the more you go nobody for you go refer station has been proposed as one of the ways out of the Climate Crisis briefly as a viable solution. Sometimes yes sometimes not a single its over estimated theres a reason why there are no trees in many areas because the soil is sale and you cant clone trees there as a regions you wouldnt like to feel with trees is a beautiful africans of venice was older animals shouldnt disappear because of open areas of it was trees however all the areas that have been de forest during the last decades by human use say should be replanted and there again we really need political activity to make it happen ok well noted professor jurgens from the south African Science Service center thank you. Thank you so for thats it for now from v. W. News africa you can catch all our stories on our web sites on the Facebook Page we need you when you look at africas why its all been landscapes so it means again a great weekend. Robots are still in the Development Phase 5 so its going to happen when they grow. Will humans and machines be able to peacefully coexist or are we on the verge of a robot collapse. If we just bumble into this totally unprepared with our heads in the sand shooting to think about what could go wrong then lets face it its probably going to be the biggest mistake in history. Artificial intelligence is now spreading through our society chaotic will experts be able to agree on ethical guidelines or will this Technology Create deadly new autonomous weapon systems. Going to school robot collapse starts aug 14th on d w. Hello and welcome to news from the world about some culture and music bias to this edition starting with what has to be the longest instrument in the world at a Music Festival in switzerland also. A spectacular light installation that visualizes what the into night internet might look like. And we take a look at georgian composer nikolaus and his mesmerizing music making machine. If you live in a mountainous region like the alps and you need to speak to a friend living on the next peak nowadays you just pick up the phone back in the day though you had to travel right down into the valley and then up the next mountain or you could blow your horn the alp hold out a kind of morse code of sound sequences which conveyed your message across the valley today its soothing tones and just used musically and weve been to the biggest outpolled festival in the world in of course switzerland. Switzerland has amazing mountain panorama its. Breathtaking. And a Musical National symbol
