Many ways you can recycle plastic west i am in kampala uganda and as always uncle hosting with my colleague. In nigeria hello everybody im now outside were coming to you from the Conservation Foundation park in Lagos Nigeria nice to have you here with us here are a few of the topics were going to be looking out on today show i mean banks are from tanzania uses innovation to make peoples lives easier. Young people in need a push back against the certification. And the greek capital athens turns to an ancient solution to face the challenge of Climate Change. First we had to tanzania to meet someone there who is known as the father of innovation burner q i was just 16 when he started tinkering with stuff and inventing things its still what he loves doing the most and he also loves to share his knowledge who visit as hes Innovation Hub where ideas get workshopped and a lot of these ideas are environmentally friendly tickle it. Where theres a will theres a way but it has taken that proverb to heart largely selftaught is an expert advice in mechanical and electrical devices this machine for example that flattens in the tubes for a drip irrigation system rock on to find the need for the point of an invention is that it has an obvious and i realised that the environment has been neglected come even though its so important to human life so i decided to focus on technology that. For the technology. To have a good. At home he installed this windmill to produce energy. It powers his homemade washing machine and pumps the water will reach from a nearby borehole. His invention isnt just environmentally friendly it also saves a lot of time and labor. When theres no wind he uses a stationary bicycle to pump water that was his 1st invention. At home we dont use power from the National Grid we can hannas energy from the sun not you and the sun is free is the power of nature you dont have to pay anything all you need to do is get the parts that you can fight sand into power and install them and you are protecting the environment or it was i was only. One of kiwi has installed a solar cells on his roof. This so lets talk is another of his inventions. The prolific innovator shares his knowledge and passion with others a few years ago he cofounded the 20 social Innovation Center in the city of i will share here he and other Staff Members over what shops and develop new ideas like using Recycled Materials to construct a wheelchair project manager jonathan z. That is here every day he and bennett regularly consult on technical issues. The social Innovation Center about 6 from the community to solve their own local challenges using local knowledge. The community can feel that we dont how we dont import this knowledge or these things from outside these are the things that we how we use them on home that we find in the local shops that can help us the center is open to anyone in the community who wants to build or repair things it also designs a lead bus serving devices for customers many of the contracts come from firemens asking for example if it might be possible to construct a machine that plants a siblings directly in the soil planted career and other inventors try to develop Effective Solutions some customers stopped by his home to see his machinery in action many interested in his solar powered water heater. Farm we hear is the most important part of the tubes theyre difficult to get but all the other things can be sourced from local 100 stores this one has used a metal for the lead a normal iron shooting of the most difficult thing is the heating tubes but i realize that i used fluorescent bulbs someone if you paint them sorry they work but what about. Built from secondhand material his son a water heater only course around 155. 00 euros about half as much as a shop. Thanks to his creativity and skill but then it has become a successful equal interpret as well as an advisor sparing innovators. And now for something were all familiar with those situations when all you want is a clean toilet and fast but many people around the world have no access to this facility or or have to make do with overcrowded and poorly maintained facilities i mean we should have in kenya is addressing this problem with its own sanitation scheme and its even member meant to be friendly the perfect candidate for this weeks doing your bit. In informal settlements in kenyas capital nairobi after 500. 00 households usually have to make do with one shared Public Toilet they tend to be wooden huts without any water. Georgina wendy lives in a slum in nairobi a 25 year old mother was apprehensive about using the Public Toilet it was not surprised that she suddenly left him it was not cool. Gems even we were infected now she shares this new blue toilet with only 4 other household toilets made by Kenyan Companies shanachie dont rely on sewers the waste is separated into liquids and solids in removable cartridges being. The toilet theyre also relatively cheap to install in the dense alleyways of new koori can imagine the process that you have to go through to be able to lay a sewer in a place that is the table of the little polluted its the Washington Post the waterless toilet is not only clean it also helps the environment the waste is collected and taken to a Treatment Facility outside nairobi where its recycled into organic fertilizer for farmers. And how about you. If you are also doing your bit tell us about it visit our website or send us a tweet hash tag doing your bit. We share your story of. Plastic waste is a global problem affecting both land and sea so im sad to say that by 2050 our oceans will contain more plastics than fish on land to the statistics are distressing some countries dont have a regulated Waste Collection service let alone a system for recycling what we need is the notion. Come up with one he developed technology for separating on naming the product something that could be used in many things take a look. This was made to be thrown away more than 100000000 tons of single use plastic is discarded worldwide every year with more and more of it ending up in the environment. These pellets could help remedy the problem says one expert theyre made of recycled plastic film and most importantly they have low levels of contamination so. This is high purity polyethylene the soul of a sneaker is made of polyethylene from waste plastic for. Plastic is very forgiving if you heat it you can mold it any way you want. Old plastic made new for further production if this industrially produced material to be used many times over that would use up fewer resources which would also have a positive effect on the environment more given the fact that less than 2 percent of plastic film gets recycled worldwide at the moment because its so difficult but it accounts for around 80. 00 to 90000000. 00 tonnes a year and its the main pollutant of the worlds oceans. Got it. In that trash a Midsized Company in germany sees a lucrative Business Opportunity with long term prospects this invention is a kind of giant washing machine that purifies plastic the entire process includes washing separating and drying. This is how the plastic comes out of the machine clean and extremely thin and its used to produce the pellets the purest on the market says michelle hope on the market demand for the pellets is great. This could prove a boon for german Waste Disposal firms like nails which have an Endless Supply of potentially recyclable material unfortunately lots of everyday objects are made from mixed materials and that makes the recycling process extremely difficult and an economical this is done as the its all this little toy car is a great example of how many different materials one thing can contain there are all kinds of plastic here polyethylene polypropylene and sometimes also polystyrene why did much mothers of all what is devoid of ideas and thats one reason why less than 10 percent of the worlds plastic is currently recycled so plastic prevention is now the order of the day. It is a stolen. The beautiful unpredictable and cannot be temped im talking about the deficit over 80 percent of nigeria along the country in west africa lies in the Sahara Desert and huge dunes quipping closer and closer to the capital. Bought an old young volunteers for the environment is sick and to be advancing desertification leading the fight children teens who in tone ill call raising other members of the funnies to join the coals. 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. Ybor him a man is building a series he just received an order for 50 ovens from the ngo volunteer how porn on view. Through who left this oven as 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 eat them. 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 this fuel some of the 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. How big my money boston route tells his family how to use the appliance. When. They dont. Know 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. The new oven costs about 15 euros and the ngo also gives credit to members of the ngo discuss the Digital Campaign the organization wants to plant trees and find people to take care of them its about taking responsibility and making things public off the lot also create a digital version then everyone can put their picture in the frame on their smartphone and support the campaign on the internet but its most important for us to show what people in the villages are doing a local way how theyre doing their local part to fight desertification and song to tell them the initiative has organized a very special field trip in the evening the pupils are to see with their own eyes how desertification keeps progressing and how Important Trees are they said memnon when theyre not far away from me on the bank of the river sand dunes here for the final trip will enable the pupils 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 sand. The gigantic dune of subtle ray at the gates of the capitol neon made. Some of these sand dunes wander up to 20 meters 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 say wow its awesome ive never seen anything like this ive never been here before its so beautiful. Yes it may be 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 explains what everyone can do to help stop the shifting of the dunes the students are pensive. Look after seeing this here im quite troubled. As you look at some point the sand could reach the town. That makes me afraid. Theres only sent here nothing grows here anymore its a real desert. The outing had a big effect on the pupils theyre 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. But its not just an african countries struggling with the effects of Climate Change many european cities are also having to adopt to changing conditions in the greek capito op and he twelves have increased in intensity and frequency in recent he is so the authorities are looking to open up an additional supply of water by tapping into an acute look at it on to the city but thats not all. The renowned athens acropolis seen from the top of nearby mount like a better for athenians like a better us is even more important nowadays because it still has traces of woodland 80 percent of the metropolis is a densely built cauldron of cement where summer temperatures easily hit 38 degrees celsius Climate Change is also aggravating conditions in the drought plagued arid landscape linear mirah valleys had enough their rising heat and a long period of heatwave creates drought and we have problems because also we do have. A different type of rains these days also due to Climate Change we have shorter periods of time that we have enormous amount of water coming down in a very short period of time so this creates flooding and flooding creates erosion so we have this double phenomenon of dryness and a lot of water which also. The land and creates land there over 3 years ago 40 percent of the areas annual rainfall gushed down here in only 5 hours and washed away most of the topsoil. Athens is one of the european cities most at risk from drought and farce fires the deforestation of the slopes of mount like a bit of has disrupted the areas microclimate as well the downpours of recent years turned roads into want water chance now athens is responding were replacing all the asphalt of the road that goes up and down the hill which is a proximately 3 kilometers taking it off and putting a special type of material that is what the permeable water is a key element when it comes to cooling athens down thats why the head of the citys water works is showing a linear average antiquity the final stretch of a fully functional aqueduct dating back to the year 125 channels 5000000 tonnes of water a year which until now simply drained. Unused into the at and su is we tried as a duck to use it in the eightys but the quality of the water then was not that great so now that we have a very good Sewerage System we can speak again about using the water of the hydrants are. Not for drinking but for other nonportable uses like for example watering plants irrigation also washing roads or washing. Waste bins so these are things that we right now often use drink up all want there to do things that is actually a great waste the aqueduct is still intact here because it runs underground for 20 kilometers its unique in europe groundwater trickles into it along its entire length which can be accessed at over 200. 00 locations downstream the National Gardens in athens is not only in a way since of retreat from the hot citys bustle its also important for the local climate the aqueduct is already irrigating the gardens that in turn cools the surrounding area. Syntagma square with a Great Parliament sits is the beginning of one of athens main shopping therof is water will also play a key role in combating heat here leonie amir villi is having 16 water fountains installed. You need say you need good areas to give them protection i believe in water cities in athens and around the world. Bucked africa now on that island which lie in the huge good between gun and ivory caused the 6 islands are National Park and home to a large number of rest including one a tease and many rare bloods are hard to travel to the islands where we are working to pursue a career. Of conservation out of cigar forest to create. People back where it is. The islands off ivory coast are a protected conservation zone west of the capital abidjan. National park rangers regularly go out on patrol. As a risk of sharing fishing even illegal tourism newsmedia the fishing people come here to freshen the channel separating the islands and lay shrimp traps for their peers are going to. Keep coming back to check whats in the traps and that he had night. Fishing in the National Park is illegal fish lay their eggs in the tangled roots of mangrove trees usually only research boats are allowed in these waters. Tourists can only visit the islands as part of guided tours they have to be accompanied by rangers and have to abide by strict rules because youre hot they dont take anything with you and dont leave anything behind court. The islands are home to rare flora and fauna. This species of plant is endangered in us and its one of 38 endemic to the west african region. The biodiversity is more or less intact and can be appreciated by locals and visitors alike. Rejects in these areas is very important i think. Ive learnt that it plays a vital role in protecting the ecosystem as someone who lives in a city i dont often think about the importance of nature. Local communities allow the government to turn their islands into a National Park. Yet the fishing ban in the 25. 00 metre conservation zone around the island is still often ignored by the villagers. Not only do the park rangers patrol the area they also raise awareness of Environmental Protection in local villages. During our patrol we saw the trim traps of we are late again. Still fishing and legally. Sometimes the transgression is only minor the borders of the zone arent always obvious. I reeled in my net but what with the waves of the current its not straight forward and back these are still waters. The lines of communication are always open between the rangers and the fisherman and thats one reason why the conservation project works on the whole about 10000 people live on the islands everyone is cooperative and the conservationists also have the support of the village chiefs. Today they have a gift for the park ranger a boy to mark the 25. 00 metres own village chief. Wants to teach the Younger Generation about the importance of conservation. When we were young we never did what our elders told us to do but today its different i know that our young people will follow our example. The Conservation Program ensures that fish stocks remain healthy so the fishermen benefit to the rangers also make sure tourist numbers dont get out of hand for. Parking a National Park on the islands which have a surface area of just 720. 00 if you had says mass towards them would jeopardize the ecosystem. There must. Be wrong so we can control all the traffic in and out of the possible in order to protect its resources its. Resource. The National Park is over 40 years old and has proved successful thanks to the respect shown by visitors rangers and people who live in the protected area. Welcome to the end of this week the show i hope you enjoyed i learned a bit about the environment if you want to know more join us on our social media platforms and some of the comment thanks for watching from the call the Vision Foundation in Lagos Nigeria and be sure to tune in next week for a new episode of off till then goodbye from kampala a wonderful week ahead.
