Living on the roof. Over. My god julia its great to have you with us on the show. Its changing and the new report from the u. N. Details the deepening crisis its a catastrophe thats not made in africa but its already hits in the cons and then todd my colleague david cmon he sent 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 in 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 how does. You 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 a 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 a spreading as average temperatures go up the well doesnt just get hotter droughts and dust storms are growing more intense our next report. On the edge of assad as it. Creeping closer and closer to the coppertone yami 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 sand dunes have formed the final trip will enable the peoples to understand the phenomenon of desertification but will also see what people can do locally to stop the spread of the desert and to anchor the sander and. The gigantic duno of subtle ray i think gates of the capitol neon made 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. Wow its awesome ive never seen anything like this ive never been here before its so beautiful. Visually. Its good maybe beautiful but its a nightmare for humans and animals so you want if 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 but. Theres only sand left here nothing grows here anymore its a real desert. So if it keeps advancing and reaches the People Living on the river now and itll be all over. Such that ill put off. 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 like its of director of young volunteers for the environment sonny welcome to africa and 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 i. Want is to be the number one through oh. Were going to need new. Or well. Were. Well ok i met one more oil busy all people. And 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 that have to do with thats it yeah because we had eyes that all wanted. Every year is like law again or 2000 thomas would lose on the only day off people really and she was so all the people in the mobile or all the seats in that comes out on the 11th so its too much or weve got all on to also had on the news and give us the news of rude things. And thats why im decided and im bent on getting it will is like neat also still it waits i was there and there was citizenship and it was it in a ship or mono so thats why you keep on or come to the lead use the consumption would be the 1st thing is a lawyer or winning big me is more like well is not their mission or their own religion so people can awaited me or they have. It and also is. Like i kind of elect ok. If france where that also. Sounds like a very smart idea to sunny i use as i could have direct young volunteers for the environment thank you. And there. Sunnys for there. Is just one of this its of hes involved in another one involves a complex lean new type of stove that runs on the waste he put in the years and then to defy the basket. And Environmental Protection in action. Xenia is learning from a master blacksmith ebro he my mama 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. Ibraheem a man is building a series he just received an order for 50 ovens from the ngo volunteer no porn on field. 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 annoyed 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. The pupils are allowed to test the oven at home for a week. His family how to use the appliance. When. 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. New oven costs about 15. 00 and the gives credit. And my next guest. Is from the university of hes studying the environment across south africa. Thanks a lot for your time now your project studies several ecosystems which mostly dry. Thats whats happening that well we study it. And compassing all the different ecosystems. Is a. Very diverse so we have to distinguish. Well in short we. 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. Affecting each other. Human activities are expanding we see disappearing. Forests. Really dramatic changes really calls for action by politicians. Down the river as drying up 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 and whose city and the reason was a lack of rainfall in westons mbia and eastern angola many months before and that caused less water and as im busy river and finally ends a car riba dam so that the remaining water have to be used for agriculture irrigation to avoid food problems and no more water was a lot to runs through the generator systems to give electricity so you see there is a cascading effect there 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 will be dramatic this will have to a metric Economic Impact and again must set up management of the 2nd systems. Dramatic problems you go nobody for you go refer station has been proposed as one of the ways out of a 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 plonk trees there as a regions you wouldnt like to fill with trees is a beautiful africans of venice was older animals shouldnt disappear because of open areas of trees. All the areas that have been de forest during the last decades by human use should be replanted and there again we need political activity to make it happen ok well noted professor jurgens from the south African Science Service center thank you. Thats it for now from v. W. News offer got you can catch all stories on the web sites on the Facebook Page we leave you with the look at africas wide open landscapes so it means again of a great weekend. The for. Them and publics under for humble on our series on tomorrow today.
