even today many of them don't know the real world. they've lived with this trauma for decades. stolen children kidnapping campaign of non-si jane starts april 28th going to tell you. hello and welcome to he who africa where we highlight green topics and ideas from africa and europe. where i'm in lagos nigeria and with me is michael phelps and you've got i love that sandra hi there i'm sundered to nobody 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 will be looking out today. we look at why bring a range of you such a dangerous profession. we also see how green fingered no wage and already letting almost 1st stop them farming. and find out how blood waste is being put to use in modern. being a ranger 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 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 of warner 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. to find. but as the rangers combed the area looking for more he receives an emergency call. colleagues in another part of the park have arrested someone suspected of having killed the buffalo. in his group 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.

a spear at least. in the process of cutting and cutting where they need. cole incident and they moved in swiftly adventurous from these specific i would say. they're moving swiftly and they managed to one of. their race paras off. the storehouse poaching traps are piling up but. it's an uphill battle the more the rangers find and dismantle the more i'm made by the poachers they have people who have dedicated their lives into manufacturing these some of this. from. there was all motorbikes which are everywhere in the shops

so a person will walk into the shops as if he's going to buy spares for their model break he does not on a motorway and he asks for the acceleration of clutch cable which he can easily buy at a cheaper price and turn it into a snare and bring it into the park some of the traps recently added to the harm that they reaped. many animals also be at the painful science this elephant almost lost to the poaches there. but one of the says that such cases are common and that is why he's always on the lookout for threats every day through out 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 resources and you do not have. enough information and enough intelligence about them then you are forced to move almost everywhere to try and get to know what is happening in part of the park so that you are sure that what you are managing is intact of one is convinced the tourist push is to create 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 could get even if i went back with a meat refund you can use it for busy and i think on here might you do in the not to study but to the day when i joined in now i will do what you do in there anybody

. in mind which i'm getting from from the packing. is the warden in charge of the enforcement in march a sinful national park he says the n.c. pushing efforts already paying off and terrorism is proving he's helped to arrest and prosecute over $700.00 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 photograph a moment it is campaign to fight plastic 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 hole which is trying to bring people together to change these and here is what it called he wrote this week

. he's getting closer to his goals stephanie halasz has been paddling for 4 weeks now from the west in german city of cold lands on the rhine to the capital by lynn in the northeast of the country. 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. after. 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 designers way of making the invisible waste playing for all to see. what's on

40 of them are i took a photograph that shows a kayaker from above public on garbage this is the average amount of garbage from one kilometer of river in germany but not in asia and we have to work to reduce that because germany has a lot of kilometers of rivers. 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. 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 of people. he's joined by new volunteers at every new stretch with

nothing it's a tie it was here around 60 cleena opposite on the water and the river bank. because i think it makes total sense to not just collect waste from the rivers thought but also from the landscape around them. and i stop that i think it's important to realize that this is not just happening in the caribbean or where i 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 it could elect him so much try amazing what people can achieve but now backed off because whether the best of contemporary artistic attempts to combine innovation and age old knowledge to construct buildings that remain cool even when the sun is beating down outside indeed sandra insan ago 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 well 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. is a construction engineer he founded a company that produces bricks out of soil. the material makes it much easier to

keep buildings cool. 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. please share your stories. there are reports that africa is a dumping ground for most of the global ways so what is being done in africa to change that our young nigerian if i you by name decide it he doesn't want anymore and so he began to do something about it lagos nigeria is filmed to a number of illegal dump sites for. the 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 rule materials it's extremely hazardous work

with and water and groaned 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 affectively trash a company in lagos has come up with an alternative solution for handling waste it's called eat terra and was founded by its fine or tunnel. generates 1000000 tons of earth on it where it's talk less of what it allows importation into the countries the difficulty in our treatment and the informal harmless if 100 don't have the knowledge they don't have the tools all the machinery to safely recall paul and dismantle the. device. the terror collects discarded devices like laptops speakers and mobile phones which are then

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

so well that they seal plans to expand operations in the near future and he's happy that the items he recycles will not end up on the legal don't sites like this one. now can you imagine growing anything on this kind of sawfish like us one here or could you imagine growing vegetables in it please that's cold when the on jocko months on end and the ground is as hard as a rock i guess what i'm talking about europe so far not on the small andrew boat no engine island of spitsbergen the extreme conditions there 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 rose herb's in vegetables here pioneering idea. this one i think looks good too and then this one tree. for the 4th one is on the table. then maher and his employees. 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 chris basler and other plants so these see that we've got the human now off to remove the tower and. yeah because we lift it from 20 to 45 so yeah definitely. they're learning to farm in the. extremes by trial and error there's no experience to draw on then marc 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 is 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 no we didn't island actually enjoy the dark season but so how do we cope with the light season is just a challenge but the dark 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 you. so big maher is trying to show that there are

other options. then talk to those ships who also have received him and this is probably good to. give in to check it out. it's amazing to have this treasure trove but given back benjamin collects the leftover plant material for composting thank you everybody should take care to get good 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'll turn lush and green we have some day soon over 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 $2530.00 degrees. isn't here i really like to do some root vegetables carrots potatoes would be nice if the greenhouse and its builders have achieved a certain notoriety hello my name is benjamin vidmar 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 too i just said you know i want to have the freshest food possible. german student ana ketzel helps out with planting in the garden she's a little more critical of the settlement in the far north. it's been present in mining disputes back and kind of personally 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 unsustainable 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 technique that we developed here can be used to grow food in this inner city it 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 model gas got to be precise way before we station as a quasi impact previously 90 percent of the island was covered with forest now only a 10th of that remains according to environmental experts trees are mostly being cut down to create farmland. but now someone has come up with an alternative fuel source tell us more sandra village does alarming 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. fear done and is a small town in the highlands of madagascar it never had its own school until

a nonprofit organization called zahara made it possible for the residents to build one. founder of the hanna has come to visit. dr hunter rami 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 palm os can slowly char . ricers can also be used they need to char in this pit for 12 hours where the 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. on our lives. they want to make pellets briquettes from the coal dust. 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 child while you can really use. you know. the small talk one from these giant get asked to respond to cut you tease they don't have to go far away. the residents used to spend hours gathering firewood for cooking. people hear it right several times a day. dr planes 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 are hannah 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 the stove like this needs just a 5th of the fuel and by using bio char instead of would the embers last even longer if 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 that up to the. design a team 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 and can be done by hand but it didn't work as hoped and still needs to be optimized. we're going for love you have to clean it out every time you use it it's always blocked up. i think that it's fair to make a pin sure every funny you can have it while i'm out. there it's more fun to do you charge for. the school is also teaching the children a few i don't know enough about gardening or the plants and trees here look planted by pupils on the school garden or. the child plants 5 trees a year and then away says if greenery and spring up in the middle of the dry grass

runs. then you should go you don't like it he certainly we can call in the field from the celebs chary africa don't we can't have people that don't look and look just to mangoes because we're not that main was growing even in the dry. land strictly she's in food so just people do stupid but you'd close. design a team wants to plant $15000.00 new trees a year together with the people of fia donna. so that's it for us week a half an hour packed with lots of environmental news and yes best global practices my name is now tied with ok enjoy the show thanks and bye bye family. and goodbye from me in uganda my name is sandra to nobody and if you'd like to know more about us then of course be sure to join us on all social media platforms
