discovered. subscribe to the documentary. hello and welcome to another edition of africa while we highlight environmental topics on ideas from europe and africa saundra to no video on this week we'll be looking out the many ways you can recycle plastic west i am in kampala uganda and as always uncle 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 out on today show. an inventor from tanzania uses innovation to make people's 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 thinking 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 flattens inner 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 realized that the environment has been neglected become even though it's so important to human life so i decided to focus on technology that works well in one of the 1st. before the technology. to your mother here 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 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 pump water that was his 1st invention. at home we don't use power from the national grid we can hanna's energy from the sun not 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 convert sun into power and install them and you're protecting the environment or it was i wasn't. one of kiwi has installed the solar cells on his roof. this so let's talk is another of his inventions. the prolific innovator shares his knowledge and passion with others a few years ago he co-founded the tender social innovation center in the city. here he and other staff members of our what shops and develop new ideas like using

recycled materials to construct a wheel chair project manager jonathan z. that is here every day he and bennett can we are regularly consult on technical issues. 20 of those which are innovation center about 6 from the community to solve their own challenges using local facility. the community can feel that we don't have we don't import this knowledge or these things from outside these are the things that we how we use them at home we find in the local jobs that can help us the center is open to anyone in the community who wants to build or repair things it also designs a level serving devices for customers many of the contracts come from firemen's 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. 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 hundreds toes this one has used a metal for the legs and normal iron shooting the most difficult thing is the heating tubes but i realize that used fluorescent bulbs someone if you paint them. built from 2nd hand 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 but then it has become a successful equal interpret as well as an advisor to other aspiring innovators. 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

facility 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 and it's even member meant to be friendly 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 a 25 year old mother was apprehensive about using the public toilet it was not surprised that 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 don't rely on sewers the waste is separated into liquids and solids in removable cartridges being. if the toilet there 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 to be populated it's just watching. the water list toilet is not only clean it also helps the environment the waste is collected and taken to a treatment facility 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 of.

plastic waste is a global problem affecting both land and sea so i'm sad to say that by 2050 oceans will contain more plastics than fish on land through the statistics are distressing some countries don't have a regulated waste collection service let alone a system for recycling what we need is solutions. come up with one he developed technology for separating on naming products it is 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 pallets could help remedy the problem says one expert they're made of recycled plastic film and most importantly

they have low levels of contamination. 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 if you can mold it any way you want. old plastic made new for further protection 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 or given 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 $80.00 to $90000000.00 tons a year and it's the main pollutant of the world's oceans. look at it. 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 the 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 to understand it's like 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 by the month most of all it is devoid of why did it 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 stolen. the beautiful unpredictable and cold no big tent 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. bought an old young volunteers for the environment is sick and the advancing desertification leading the fight children teens who intel on alcohol raising other members of the a funny to join the coals. and environmental protection in action. xenia is learning from master blacksmith ebro human 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 . it for 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 eat on. them 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 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 . sorry use of wood what. the pupils are allowed to test the oven at home for a week. how bad my money boston route tells his family how to use the appliance. when. they don't. always act and it seems easy to use it produces hardly any smoke and you don't need to use wood anymore 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. at large 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 a local way how they're doing their local part to fight desertification and solving the problem of 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 memnon when they're not far away from me on the bank of the river sand dunes have formed the field 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 doune of subtle ray at the gates of the capitol neon many. some of these sand dunes wander up to 20 meters a year depending on the wind their height can reach 30 to 40 meters the pupils are overwhelmed once they get to the top seed 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 if you don't want sand there instead bury your homes you have to try to prevent them from shifting. with sand drift fences for example going to sunnier you but 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 send 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 adapt to changing conditions in the brick capito op and hit waves 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 i sent a kid up to 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 thin aeons 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 with summer temperatures easily hit 38 degrees celsius climate change is also aggravating conditions in the drought plagued arab landscape linear mirror valleys had enough there rising heat and the long periods

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 of has disrupted the area's microclimate as well the downpours of recent years turned roads he into want water tarrant's 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 a rare antiquity the final stretch of a fully functional aqueduct dating back to the year 125 a channel's $5000000.00 tonnes of water a year which until now simply drained. unused into the at and sue 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 the hydrants arca 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 says 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 the greek parliament sits is the beginning of one of athens main shopping for affairs 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 then you need water like i made 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 rest including one ities and many rare bloods are trying to travel to the islands where they are working to preserve the. conservation out of pigs are coming forward to the region. people are back where

a bit harder to get. the islands off ivory coast are protected conservations own west of the capital abidjan. national park rangers regularly go out on patrol. so there is a risk of approaching 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. here we are. 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 take anything with you and don't leave anything behind in court. the islands are home to rare flora and fauna the scene of this species of plant is endangered in a city that it's one of 38 that are endemic to the west african region. where software . the biodiversity is more or less intact and can be appreciated by locals and visitors alike. rejected 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 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 are we are late again. still fishing and legally. sometimes the transgression is only minor the borders of the zone aren't always obvious and. i reeled in my net but what with the waves of the current it's not straight forward and back 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 1st. time clock a national park in the islands which have a surface area of just $720.00. masters and would jeopardize the

ecosystem. you must. be a youngster we control all the traffic in and out of the past in order to protect its resources its. supper 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 this week's 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 so i will 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 africa till then goodbye from. a wonderful week ahead.
