even today many of them don't know who their real names were. they've lived with this trauma for decades. telling children the kidnapping campaign of non-si journey starts april 28th going to tell you. hello and welcome to who africa where we highlight green topics and ideas from africa and europe. and i'm in lagos nigeria and with me is my co-host and you got a little bit sandra hi there on sunday to know we are here in kampala uganda and in this week's show we go to germany to meet a month who's hoping to turn the tide when it comes to plastic pollution in the way

that he has some other topics we'll be looking at today. we look at why bring a raincheck in such a dangerous profession. we also see how briefing that no wage and hour unloading almost 1st stop them from inc. and find out how blood waste is being put to use in much augusta. being a ranger it can be a dangerous job some $100.00 wildlife guardians lose their lives each year in their line of duty many of them in east and central africa well accidents account for about 50 percent of those fatalities porches were responsible for the other half we went to months and forced national park here in uganda to meet julius or one now the warden in charge of law enforcement there he has been confronting these day in day out for more than 20 years.

in the morning roll call julius one a tells his men that poachers have set traps during the night to capture animals. they have to move fast to save the animals lives after covering a few kilometers and foot with his men. but as the rangers combed the area looking for more he received an emergency call. colleagues in another part of the park to rest someone suspected of having killed the post below. in his group and got away. the rangers confiscate the meat of the animals here have protected status no hunting is allowed. that came from their communities of course. they came with.

spears. and in the process of cutting on where they need. coal for the incident they moved in swiftly at ranges from these specific outpost. they moved in simply and they managed to one of. their race. at the storehouse piling up. but. it's an uphill battle to move a radius find and dismantle the more i'm lead by the poachers there are people who have dedicated their lives into manufacturing these some of the scenarios. from. words of motorbikes which are everywhere in the shops

so a person will walk into the shops as if he is going to buy spares for their model break he does not on a motorbike and he asks for the acceleration of clutch cable which he can easily buy at you pop price and we turn it into a snare and bring it into the park some of the traps getting rid of the harm that the. many animals also be at the painful science this elephant almost lost a truck to the poachers. of one of this is that such cases are common and that is why he's always on the lookout for threats every day through the park. out there we know we have people who will always want to force themselves into a protected area to try and get these resources and. where they come

to get these are sources and you do not have. enough information enough intelligence about them then you are forced to maul almost everywhere to try and get to know what is happening in part of their park so that you are sure that what you are managing is intact. of oneness convince the tourist poachers to quit the illegal wildlife trade by offering them work. people like out that. he's happy with his transition from poacher to gamekeeper of the lone buffalo almost killed him on foot patrol. he knows exactly the movements of the poachers because when i was putting nothing i couldn't get even if i went back with the meat in a 400 you can use it for pussy and i think i had it my to do in the not to study but to the time when i joined in now i would do it you didn't hear anybody in school in

money time getting from from the parking. but does possibly one is the warden in charge of law enforcement in march is unfolding national park he says the anti pushing efforts are already paying off and tourism is good. has helped to arrest and prosecute over 700 poachers in the area julius obama has witnessed the population of elephants grow in the last 25 years from less than 400 of the animals to over 1600 today. someone 4 to graf a house mounted an inspiring campaign to fight plus the pollution around the world $322000000.00 tons of plastic is produced each year and you can find plastic was literally anywhere much of it ends up in the rivers stephon which is trying to

bring people together to change these and here is our call here this week. he's getting closer to his gold stephanie halasz has been paddling for 4 weeks now from the west in german city of copeland's on the rhine to the capital by lynn in the northeast of the country. the doors are falling as even or as on the greatest thing and this was a trip of 750 kilometers it was to come up against your limits when you think you'll never make it then you get a 2nd wind and then you do it because this is not my shaft to being. he started out doing the collecting on his own he'd make an arrangement of the garbage from the rivers photograph it and put it on display it's the photo designer's way of making the invisible waste plain for all to see. up on

for 2 of them are i took a photograph that shows a kayaker from above paddling on go. ridge this is the average amount of garbage from one kilometer of river and it will be different in germany but not in asia and we have to work to reduce the odds that germany has a lot of kilometers of rivers trying to reach the feet of who's going to make it. in total around 7300 kilometers and stefan horse has only travelled a fraction of them so far. alongside exhibitions he also organizes regular cleanup events 7 cities are taking part in this one like oberhausen on a tributary of the rhine. and what you have to look closely i pull out pieces of plastic all over the place to look just like the stones my boats already full up. he's joined by new volunteers at every new stretch with nothing it's sawing resin

here around 60 cleena opposite on the water and the river bank. i think it makes total sense to not just collect waste from the rivers thought but also from the landscape around them. and their eyes. i think it's important to realise that this is not just happening in the caribbean or wherever be aware that it starts here with us i'm saying this. after just 2 hours they've gathered around 2000 liters of garbage. stephanie halasz needs as many fellow campaigners as he can get because that's plenty of work to do. but he's happy to have come this much closer to his goal of clean water waves.

while they were equal to the so much trosch amazing what people thought can achieve but now bucked. because whether the best of contemporary attempts to combine innovation and age old knowledge to construct buildings that remain cool even when the sun is beating down outside indeed sandra in santa go a group of young engineers and architects have joined forces instead of congress they use oil to make compressed earth breakers it's an economical and sustainable building method now let's have a look see how far their work has gone. in senegal the summers are swelteringly hot without air conditioning life can get unbearable especially if you live in a concrete building. do jem is a construction engineer he founded a company that produces bricks out of soil. the material makes it much easier to

keep building school. level to one of the benefits is that the thermal insulation stops cool air from escaping where a cement instantly lets heat in so you have to use air conditioning all the time you can't switch it off because as soon as you do the walls absorb the heat and let it in. the red soil and senegal is perfect for making compressed earth blocks. after $21.00 days left to dry in the sun there ready to be deployed. building with soil is a traditional technique but over the years the method has been refined the mixture used here contains 10 percent cement making the bricks more stable and water resistant building using earth bricks is far better for the environment than using pure concrete. production of the brick involves a far lower rate of c o 2 emissions plus residents have less need for air conditioning.

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. there are reports that africa as a dumping ground for most of the global ways so what is being done in africa to change that our young nigerian if i abide decide it he doesn't want any more and so he began to do something about it. lagos nigeria is filmed to a number of illegal dump sites free weights for many local people the refuse is a vital source of income of the taking of poets t.v.'s computers and other devices by hands they resell the components as raw materials it's extremely hazardous work

with and water and ground severely polluted by heavy metals and toxic chemicals some electronic devices come from developed countries in the form of the nation's unfortunately only a fraction of food and functional the rest is effectively trash a company in lagos has come up with an alternative solution for handling the waste it's called eat tara and was founded by if klein or tunnel nigeria usually generates $1000000.00 tons or tonic with talk less of what it allows importation into the country the difference between our treatment and the informal homeless if i want to live don't have the knowledge i don't have the tools all the machinery to safely be caught and dismantle. the device. the terror collects discarded devices like laptops speakers and mobile phones which

are then checked over at the company's material recovery for 30 those parts that can still be used i restored and mostly d.n.a. to this charity the rest is dismantle the terror has invested in the range of machinery it allows the workers to dismantle the waste in a way that is safe for the environment and for themselves and exhaust hood is used to contain the toxic feed. you're not blurred you can have so many carcinogenic materials that are trapped there sucked out and trapped trapped inside it's our diminishing tricks are effectively detoxified while we dismount. so all of the glass and all of the. plastic. parts of being dismantled the waste is separated in shreds they're all material salvaged such as i live in the glass and i and the company's main source of income. business has been doing well

for the company so well that they seal plants expand operations in the near future and he's happy that the items he recycles will not end up on the legal dump sites like this one. now can you imagine growing anything on this kind of sawfish like bush one here or could you imagine growing vegetables in it please that's cold windy on top of months on end and the ground is as hard as a rock i guess what i'm talking about europe's fun off on the small angry boat no engine island of spitsbergen the extreme conditions that make you apologize for research as i venture is like benjamin britten his mission to boldly grow what no one has grown before that's good check it out. finally a little light every day in winter the darkness here stretches on for months it's minus $25.00 degrees celsius and the ground is permafrost there are more polar

bears than humans on spitsbergen. but one of those humans benjamin did mark grose herb's in vegetables here a pioneering idea. this one i think looks good too and then this one tree. for the 4th one is on the 3 of us and then maher and his employee hey give harvest the crops grown in the lab as he calls this room. it has an almost tropical climate in the midst of a frozen wilderness and he's planted cress bezel and other plants think these see that we've got the human now off to. the military and. yes because we lift it from 20 to 45 yeah definitely so they're learning to farm in these extremes by trial and error there's no experience to draw on then mark came up with the idea because he was desperate for fresh produce one day he even hopes to grow some tomatoes they

would be the northernmost crop of them on earth. it's pitch black here by 3 in the afternoon benjamin's used to that by now. he's originally from florida but 10 years ago the ship's cook washed up on the shores of the icy norwegian island actually enjoy the season but so how do we cope with the light season as that's the challenge but season is very relaxed don't have to do too much but when the light comes. we get very busy and you have to run all of the time. whether dark or light vid mars business is booming he's barely able to keep up with demand and capacities are limited spitzbergen is located nearly a 1000 kilometers north of the next populated settlement practically everything has to be flown in including produce this other stuff but that's expensive and bad for the environment some greens for the. soviet mar is trying to show that there

are other options. talk to those ships who also have received in this common good to. have been to make sure you know. it's amazing to have this treasure trove. given back benjamin collects the leftover plant material for composting thank you every country should take care you could go yes thank you. this isn't a u.f.o. it's the gardener's greenhouse in the darkness of the polar night it's 20 below in here but when spring brings back the light it will turn lush. green we have some days you know with the midnight sun there's sun in theory 24 hours a day so it just moves around in the sky and it can get like 2530 degrees in here i really like to do some root vegetables carrots potatoes would be nice for the greenhouse and its builders have achieved a certain notoriety hello my name is benjamin button mar and doing this tour with

you today we were nearly every day he has a lot of curious visitors. i didn't started to save the world i didn't start it i just said you know i want to have the freshest food possible. german student helps out with planting in the garden she's a little more critical of the settlement in the far north. it's been physically seminude us bits back we're certainly i don't see spitzbergen as a place where people should be living. because it's got such an extreme climate and it's so i'm sustainable to live here but there will never come a time when people don't live here so i think it's a very good idea to try growing your own plants here. but harbaugh says it's about more than just having fresh vegetables on spitsbergen. this techniques that we develop here can be used to grow food in this inner city can be used to grow food on different islands so it has many. applications to other places as well so if we

can do it here it can be done anywhere this is the most challenging place to do it . benjamin did not believe that if his ideas can take root in spitsbergen they could grow practically anywhere. from i see no way so africa so modern gas got to be precise where the forward station as oak washing impact previously 90 percent of the island was covered with forests now only a 10th of that remains according to environmental experts trees are mostly being cut down to create farmland or. but now someone has come up with an alternative fuel source tell us more sandra village elders are launching a new process in which they can tell on plant waste on dry grass into fuel pellets it is so much better than cutting down the mall. fear done and is

a small town in the highlands of madagascar it never had its own school until a nonprofit organization called zatanna made it possible for the residents to build one. founder of the hana has come to visit. talk to run me on tania revoke wants to increase environmental awareness and make sure that it's established in the school curriculum. the team is prepared a series of workshops. and the rambles on runs a course on bio char a charcoal produced from plant matter. the residents collect drawing grass and leaves press them in to predict holes in the ground and carefully light them. they then quickly seal the hole to cut off the air supply so the biomass can slowly char . rice husks can also be used they need to char in this pit for 12 hours with a restricted air supply says it looks good but the waste from the rice harvest has

charred nicely we can empty out the contents now to process it. leaves them. they want to make pellets and briquettes from the coldest. they are diluted clay to the biomass to glue together so they can then need it into bio char. it's a far better fuel source than would be burns for 10 times longer and using bio char also has another advantage. to make charcoal i usually use. you know so we fit with the small talk one from these 2 i get asked to respond to cut you tease fear don't have to go far away. the residents used to spend hours gathering firewood for cooking. people hear it rice several times a day. dr plains now cover the land where forests used to grow everything has been

cut down. there are only trees in the town now which the organizations ahana replanted. the best way to burn bio char is in special clay ovens protected from the wind. and the runnels on teaches the residents how to make them. the women are already using the ovens to cook at school. but the zohan a team wants to convince everyone that a stove like this needs just a 5th of the fuel and by using bio char instead of would the embers last even longer the old habits die hard though winning people over takes patience despite the many advantages what do you all know musea saves a lot of fuel. stays inside. and it's much faster to cook. is testing out

a new machine that could help them produce by a char. it was highly praised by technicians from the provincial capital. the machine is supposed to press and compact the bio mass in the cylinders more effectively than can be done by hand but it didn't work as hoped and still needs to be optimized. in for love you have to clean it out every time you use it it's always blocked up. i think that is fair to make you can shoot every fun you can have a while and. it's more fun to do you charge by. the school is also teaching the children a few i don't know about gardening or the plants and trees here were planted by pupils on the school garden or. each child plants 5 trees a year and in a way says of greenery a spring up in the middle of the drawing grasslands. then you see you

go you don't like the surface we can come over in the sheen from disallow and cherry i forget i don't think and have people that don't look and look just to mangoes because we're not that many was growing even when they're dry. land strictly she's a poof so just people do stupid but she drew. design a team wants to plant $15000.00 new trees a year together with the people of donna. so that's it for us week half an hour packed with lots of environmental news and the year's best global practices my name is now tied with i hope you enjoy the show thanks and bye bye from lagos and goodbye from me in uganda my name is sandra to nobody and if you'd like to know about us then of course be sure to join us on all social media
