the powerhouse of man does cross all her. with ideas that are our future somehow a part of. this world our documentary stories may. hello and welcome to another edition of africa where we highlight environmental topics and ideas from europe and africa saundra to nobody on this week we'll be looking out the many ways you can recycle plastic west i am in kampala uganda and as always i'm co-hosting with my colleague. in nigeria hello everybody i'm now

outside we're 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 we're going to be looking at on today show. an inventor from tanzania uses innovation to make people's lives easier. young people in a nice way 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 asian burnout q i was just 16 when he started tinkering with stuff and inventing things it's still what he loves doing the most and he also loves to share his knowledge with visitors his innovation hub where ideas get workshopped and a lot of these ideas are environmentally friendly take a look. where

there's a will there's a way but it has taken that proverb to heart largely self-taught he's an expert at devising mechanical and electrical devices this machine for example that flattens in the tubes for a drip irrigation system you walk 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 it's so important to human life so i decided to focus on technology that works well in one of the 1st. 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 from a nearby borehole. his invention isn't just environmentally

friendly it also saves a lot of time and labor. when there's no wind he uses a stationary bicycle to comp water that was his 1st invention. at your home we don't use power from the national grid we can harness energy from the sun or you and the sun is free is the power of nature you don't have to pay anything all you need to do is get the parts that converts sun into power and install them and you're protecting the environment it was amazingly. well it has installed the solar cells on his roof. this solar storm is another of his inventions. the prolific innovator shares his knowledge and passion with others a few years ago he co-founded the trendy social innovation center in the city i will share here he and other staff members of our what shops and develop new ideas

like using recycled materials to construct a wheelchair project manager jonathan zira is here every day he and bernard can we are regularly consult on technical issues. 20 is a social innovation center that seeks to the community to solve their own local challenges using local authorities. the community can feel that we don't how we don't import this knowledge or these things from outside these are the things that we how we use them at 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 repaired. things it also designs the levers severing devices for customers many of the contracts come from farmers asking for example if it might be possible to construct a machine that plants a sibling's directly in the soil planted kiwi 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. the farm where he has the most important part of the tubes they're difficult to get but all the other things can be sourced from local hardware stores this one has used a metal folding lead a normal iron shooting of the most difficult thing is the heating tubes but i realize that i used fluorescent bulbs can work if you paint them sorry workable way about. built from secondhand material his son a water heater only costs around $155.00 euros about half as much as a shop. thanks to his creativity and skill. has become a successful equal interpret as well as an adviser sparing innovative. and now for something we're 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 or

or have to make do with overcrowded and poorly maintained facilities i mean we should save in kenya is addressing this problem with its own sanitation scheme. differently the perfect candidate for this week's doing your bit. in informal settlements in kenya's capital nairobi up to $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 the 25 year old mother was apprehensive about using the public toilet it was not surprised that suddenly it was not cool. jams even when we were in fact. now she shares this new blue toilet with only 4

other household toilets made by kenyan companies shanachie don't rely on sewers the waste is separated into liquids and solids in removable cartridges beneath the toilet they're also relatively cheap to install in the dense alleyways of new kourou can imagine the process that you have to go through to be able to live in a place that is that. it's actually. the water of the toilet is not only clean it also helps the environment the waste is collected and taken to a treatment. so the outside nairobi where it's 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.

plastic waste is a global problem affecting both land and sea so i'm sad to say that by 2050 our oceans will contain more plastics than fish on land to the statistics are distressing some countries don't have a regulated waste collection service let alone a system for recycling what we need is the notions i've. come up with one he developed technology for separating on naming the product into something that could be used in many people 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 they're 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 film 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 for you the fact that less than 2. percent of plastic film gets recycled worldwide at the moment because it's so difficult but it accounts for around 80 to 90000000 tonnes a year and it's the main pollutants of the world's oceans. are. in that trash a mid-sized 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 it's 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 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. that month most of all what is devoid of ideas and that's one reason why less than 10 percent of the world's plastic is currently recycled so plastic prevention is

now the order of the day. it is a stunning good beautiful unpredictable and can not be temped i'm talking about the death that over 80 percent of niger along the country in west africa lies in the sahara desert and huge dunes are quipping closer and closer to the capital niamey bought an old young volunteers for the. it is sickening to be advancing desertification leading the fight children teens who intel on alcohol raising other members of the funny 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. ibraheem a man is building a series he just received an order for 50 ovens from the ngo volunteer how porn on feel. to food left in the well this oven is a tool in the fight against desertification because it's not filled with wood but with rice husks the husks can't be used for anything else not even animals a ton of i don't like but every day tons of rice husks accumulate in the state rice factory it's waste with no nutritional value everyone who has an oven can get it here for free to use as 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 bad my money bossa route tells his family how to use the appliance. when. you know we act and it seems easy to use it produces hardly any smoke and you don't. need to use wood any more that's good i want to try the oven out properly. the new oven costs about 15 euros and the in geo 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 it's about taking responsibility and making things public. would 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 it's most important for us

to show what people in the villages are doing locally how they're doing their local part to fight desertification one really thought about 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 this is. not far away from me on the bank of the river sand dunes have formed 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 dunes. the gigantic dune of settler a i think gates of the capital niamey. 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 it's awesome i've never seen

anything like this i've never been here before it's so beautiful. it's good maybe beautiful but it's a nightmare for humans and animals so you want it you don't want send there instead bury your homes you have to try to prevent them from shifting. with sand drift fences for example you know that sunny are you explains what everyone can do to help stop the shifting of the dunes the students are pensive. after seeing this here i'm quite troubled. as you look at some point the sand could reach the town. that makes me afraid. there's only sand left here nothing grows here anymore it's a real desert. the outing had a big effect on the pupils they're now motivated over the holidays they're going to environmental camps where they will set up sandra fences and plant trees anything

and everything to stop desertification. but it's 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 capital offerings he twelve's have increased in intensity and frequency in recent years 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 that's not all. the renowned athens acropolis seen from the top of nearby mount like a better house for athenians like a battle says 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 the 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 depletes the land and creates land there over 3 years ago 40 percent of the area's 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 as has disrupted the area's microclimate as well the downpours of recent years turned roads he into want waters taunts now athens is responding we're 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 that's why the head of the city's waterworks is showing leonie a rare antiquity the final stretch of a fully functional aqueduct dating back to the you 125 a channel's 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 80s but the quality of the water then was not that great so now that we have a very good serious system we can speak again about using the water of 300 as i could not for drinking but for other non-portable uses like for example the watering plants irrigation also washing roads

or washing. waste bins so these are things that we right now often use drink of the water to do things that is actually a great waste the aqueduct is still intact here because it runs underground for 20 kilometers it's 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 city's bustle it's also important for the local climate the aqueduct is already irrigating the gardens that in turn cools the surrounding air. syntagma square with a great parliament sits is the beginning of one of athens main shopping for a famous water will also play a key role in combating heat here leonie amir

a village is having 16 water fountains installed. you need say you need good areas to give them protection then you need water and you need that public water fountain. so that people can drink water. water and woodlands to cool baking cities in athens and around the world. bucked africa now on the islands which lie in the huge good between gun and ivory caused the 6 islands are national park and home to a large number of respite including one a tease and many ramp odds are trying to travel to the islands where they are working to persuade. a conservation out of cigs are coming forward to the region to create. people back where it's harder

to get. the islands off ivory coast are protected conservations owned west of the capital abidjan. national park rangers regularly go out on patrol. as a risk of fishing even illegal tourism. fishing people come here to freshen the channels separating the islands and lay shrimp traps for. them i keep coming back to check what's in the traps and. he and i promise in a couple of he'll be. 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 you're hot they don't have to take anything with you and don't leave anything behind in court. the islands are home to rare flora and fauna you see this species of plant is endangered when i see that it's one of 38 that are endemic to the west african region. west africa. the biodiversity is more or less intact and can be appreciated by locals and visitors alike. since about security checks in these areas is very important i think. i've learnt that it plays a vital role in protecting the ecosystem as someone who lives in a city i don't often think about the importance of nature. local communities allow the governments 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 tramp traps of reality began. still fishing and legally. sometimes the transgression is only minor the borders of the zone aren't always obvious. i reeled in my net but what with the waves of the current it's not straightforward these are still waters. the lines of communication are always open between the rangers and the fisherman and that's one reason why the

conservation project works on the whole about 10000 people live on the islands everyone is co-operative 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 it's 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 don't get out of hand. park a national park in the islands which had a surface area of just $720.00. masters and jeopardize the

ecosystem. must. control all the traffic in and out of the possible in order to protect its resources is to. say. 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 the show i hope you enjoyed it i learned a bit about the environment if you want to know more join us on our social media platforms and comment thanks for watching on the call the vision foundation in lagos nigeria and be sure to tune in next week for a new episode of africa till then goodbye from. a wonderful week ahead.
