oh after 100 lives the ideals of the bombs are more relevant today than they were a 100 years ago visitors shapes things to come because people understood the sign as a way of shaping society. because for 3 part documentary starts nov 14th on t w. hello and welcome to another edition of africa where 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 quest 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 out on today show i mean venture 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 bernard 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 who 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're going to find the need for the point of an invention is that it has an obvious benefit i realized 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 were invariable go. for the technology. to have a game. at home he installed this windmill to produce energy. it

powers his homemade washing machine and pumps the water full reach from a nearby bogle. thanks to. 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 the 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 converts sand into power and install them and you're protecting the environment or it was amazing you. managed 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 10 day 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 john is here every day he and bennett regularly consult on technical issues. which are innovation center that seeks to the community to solve local challenges using local authorities. the community can feel that we don't have we don't import this knowledge or views things from outside these are the things that we have we use them at home 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 the levers saving 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 tried to develop effective solutions some customers struck by his home to see his machinery in action many interested in his solar powered water heater. the farm we hear is the most important part of the tubes they're difficult to get but all the other things can be sourced from local hardware store as this one has used a metal for the lead a normal iron shooting the most difficult thing is the heating tubes but i realize that used fluorescent bulbs can work if you paint them. but what 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 but then it has become a successful equal interpret as well as an advisor sparing 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. 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. the genome a 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 we were infected now she shares this new blue toilet with only 4 other households the toilets made by kenyan company shanachie don't rely on sewers the waste is separated into liquids and solids in removable cartridges big. if the toilet they're 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 polluted it's the washington post. 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. plastic waste is a global problem affecting both land and sea so i'm sad to say that by 25th oceans will contain more plastics than fish online 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. all of 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 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 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 tonnes a year and it's the main pollutant of the world's oceans. that it was. 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 i hope i'm 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 linus that's 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 my mother's 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 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 quipping closer and closer to the capital niamey bought an old young volunteers for the environment is sick and the advancing desertification leading the fight children teens who intel on other members of the funny to join the coals.

and environmental protection in action. xenia is learning from master blacksmith even 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 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 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. you know we 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. 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 a local way how they're doing their local part to fight desertification. to tell them what 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 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 it's awesome i've never seen anything like this i've never been here before it's so beautiful. it's good may be beautiful but it's a nightmare for humans and animals so you want if you don't 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. and. 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 country is struggling with the effects of climate change many european cities are also having to adopt to changing conditions in the brick capito op and her 12 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 that's not all. the renowned athens acropolis seen from the top of nearby mount like a better house for athenians like a better 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 arid landscape linear mira 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 get the 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 leaves 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 fast fires the deforestation of the slopes of mount

like a better so has disrupted the area's microclimate as well the downpours of recent years turned roads into white 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 leonie a rare antiquity the final stretch of a fully functional aqueduct dating back to the year 125 it channels $5000000.00 tonnes of water a year which until now simply drained. unused into the at and su is we tried 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

architect not for drinking but for other non-portable 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 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

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 villi is having 16 water fountains installed. you need say you need good areas to give them protection and you need water like any 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 coast the 6 islands are national park and home to a large number of respite including one a tease and many rare bloods are starting to travel to the islands where they are already working to preserve. a conservation out

of seeds are covering stories to create. people back where it's hard to get. the islands off ivory coast are protected conservations own west of the capital abidjan . national park rangers regularly go out on patrol. as a risk. fishing even illegal tourism newsmedia. fishing people come here to freshen the channel separating the islands and lay shrimp traps for. the pit and i keep coming back to check what's in the traps and been pointed out here and i promise in a couple if you're. 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 the devil take everything with you and don't leave anything behind any court. the islands are home to rare flora and fauna you see this species of plant is endangered in this and it's one of 38 that are endemic to the west african region along with off into. 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 be again. still fishing illegally. 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 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 for. them to park here in the national

park and the islands which have a surface area of just $720.00 if you had says mass tourism wouldn't jeopardize the ecosystem. are going to live there must risk. their will control all the traffic in and out of the park 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'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 some of the comment thanks for watching 'd on the call the vision foundation in lagos nigeria and be sure to tune in next week for the new episode of
