musicians compose their understanding of nature. to mark the 250000 of verse 3 of the composer's birth like sharon program advice of not you know he's good. beethoven worldwide. astral project starts to come forth on t.w. . a very warm welcome to this week's episode of africa i am sondra to nobody coming to you from kampala here in uganda the pilot of africa where we do start by asking you did you know that this is not a match of foods that have disappeared from my dad's almost completely even though they're. so resistant to environmental influences one such school is now making

a comeback in mali and this is going to interest you hi sandra yes and i can't believe it we always have many good tips here on eco africa. in the nation's capital and i just kept. let's take a look at what's coming up on the show today. the climate resistance green that's becoming popular in mali we'll tell you why the ugandan teenager who is championing climate change activism will tell you how and the women in zimbabwe training to be rangers to fight poaching we'll give you the details. the phony a green has grown in africa west africa for around 5000 years and with more and more areas being given over to rice had largely disappeared the extremely small grain can be difficult to peel but he contains many more new trends than say why bryce in mali for instance many farmers are now switching back to this form of

millet as he copes well with the i would conditions in the region making it a good option in an age of climate change where the farmers are regularly suffering crop losses. it's harvest time in the district in the central eastern region of mali near the border of book enough so the harvesting for neo a crop native to west africa a kind of minutes with small seeds and excellent properties it's one of the for. just growing crops in the world it grows in dry climates and sandy soil even without irrigation for a long time for me it was neglected but now more and more farmers are growing it again. is one of them. where you have to take land degradation into account. folio is much in demand again

now because it helps protect the soil. when you. force after the phone your husband cut the stems are left in the ground. and that helps to fertilize the soil. paramedic effectively. because the grains are small processing them is very time consuming traditionally for new is threshed on straw mats then the seeds are mixed with sound and pound it in a mortar it takes hours to extract a couple of kilos of the edible part of the grain. but things have changed here since the swiss ngo health hit us provided new machines that make it much easier to process the grains the one machine separates the grains from the stands. the other removes the husks in no time. that saves these women a lot of work now they only need to sift the grains to remove any remaining impurities. we used to have

to pound the grains till our hands got red and sore but thanks to the machines from how they're to us we don't need to do that anymore now it's far less strenuous we can just wash the grains and put them in the pot to cook. the grains are used to make porridge course course bread and also beer. ibrahim slowly month one car runs a restaurant in the capital bomb a call. for new used to be reserved for special occasions and festivities but now it's becoming a daily staple. we wash the phone you're very thorough and we prepared in such a way that people can eat it at any time. we served with 2 kinds of sources a peanut sauce. or a tomato sauce. but the most popular dish on the menu what about feeding his

mango chicken with for you. many guests come especially for that. phone you know is really the best food in mali we eat it all the time at home. i often asked my wife to make it for me but we've come here as a special treat because it's so incredibly good the way they make it here. for you is not only tasty it's also very nutritious. scientists say it has exceptional qualities making it superior to rice and corn. is a nutrition expert at the institute for rural economy in bamako. i'm nothing it is very rich in essential amino acids which are important for the body. it is a product that is very rich in fiber. so it is more digestible than other kinds of

millet rice and corn. back in tommy p.l.t. that is teaching our younger colleagues how to make calm passed. in order to facilitate the process they cover the pile with straw. the foreign you know stems protect the compost from the sun. so there are many reasons why this ancient staple of grain is regaining popularity in mali yet the demand for for new has been growing in recent years and its price has been rising to this gives farmers an opportunity to boost their income. what happens when you cut down the tree in your garden well it's one tree less you might say well what happens when thousands of trees disappear in one region they fax consume

the felt the ground dries out the humidity goes down and biodiversity is reduce not a happy event eco check has the facts and the fia's. every year around $2800000.00 hectares of forest are lost on the african continent that's about the size of equitorial guinea. and most of the forests are cleared to provide space for farming a full 93 percent for shifting cultivation. a lot of the timber is used as firewood or turned into charcoal both vital energy sources for rural populations. charcoal is also exported 40 percent of the charcoal imported to the european union comes from africa. deforestation contributes to climate change

and to a loss of biodiversity. as a result of poaching on the clearing of woodlands the forest elephant population in central africa declined by 2 thirds between 20082016. but this is good news too thanks to a range of reforestation projects. 27 african countries and to plant 100000000 hectares of new forest by 2030 that's an area almost 3 times the size of germany. so are you prepared to plant trees now the situation of forests is very serious as we've heard and one young climate change campaign from uganda is taking action. and guess what she's just 15 years old yes len i'm going to haunt the ideal planting trees on the block they use instead of having the tradition ok drinks and parties

she's also the money auction from the knuckle on global leaders to come to the negative impacts of climate change we recently made the point. here that i'm a big. you're going to. be an i'm a good ways leading this protest against climate change in the ugandan capital of kabul students are taking to the streets to be a part of the global movement for ideas the future of government action to curb climate change. there is and my purpose is that we are young people and we're fighting for our future and repurchased ever afraid to face the mother nature i think people my age are coming to protest because they know they have the biggest stick in our future and they're trying to fight for it when

a time 15 last year she didn't want to kick or to party instead she decided to celebrate her birthday by planting 200 trees. you know she launched a tree to complain with the trees which go to a lot of attention since the people in uganda planted over 3000 trees. as they were given back to the planning. of. it but. it's. been. banned. but. that is suitable for a forest and much of the space is used for agriculture that is why the young

activist wants the government. to do the trees the major reason. she has also convinced some land owners. to plant trees will be a private land if i had planted. the forest. and. plant. trees. despite some resistance more and more students in uganda joining. every friday. boarding school to strike for climate justice demanding government action against the global climate crisis. the campaign is going viral on social media i want the government to know that this climate action is real and it's needed now

this is taking place so i wonder gummidge also get to see what you're going through and they also but under such a bunch of various possibilities. doesn't shy away getting her hands dirty she and i thank you for activists into lake victoria which is not far from high school. together they collected plastic wistrom it shows and encouraged locals to do the same. she also started an online campaign to force the government to ban plastic bags in uganda and then we can learn just preach and preach and so people are doing this practicing what you preach when they 1st started their live show clean ups before and a lot of rubbish because it was. and everyone would just throw our ambition their legs but since they started seeing us cleaning their legs people have now a very good chance to us when they see as their lake we are going to clean the lake

now and they're being called part 2 they know that it's known traitor for the repetition that. even with some of the rubbish on the lake cleaned up you know i'm going to face this huge challenges fortunately she can count on her family to support her how far they've been peaceful the seedlings his 1st public criticism for his daughter as activism but he say's that you'd rather see her all industry fighting for a good cause than staying silent when the planet needs the help. to the center team but houses have been built in europe for hundreds of years the surprising thing is that the houses and up on the brits are not always so very sustainable that is why some villages examinee are starting to adopt the style once again let's take a look at one of these new but only clusters houses. this picture

s. backdrop looks like something out of a fairy tale but old have tempered houses can be found in many european cities. the tradition dates back to the 12th century buildings are constructed from a wooden structure filled with brick or loam that made sense wood sand and clay were all freely available materials. this have timbered house is not even one year old yet it was built using the old methods have timbered inside and outside for owner nor about hoffman it was important to have a low energy home equipped with the latest technology but the roof too is based on a historical design it's a so-called cold roof which is well ventilated. that's an old building technique in the sense that in the past they were only called rubes and you notice

that in the old buildings where attics are not insulated in the summer it remains a quite pleasant temperature at the top of the house but that's all it down to the way it's constructed. at the same time the heating technology in the house is cutting edge of fuel cells supplies the building with electricity a solar thermal system provides warm water on the ground floor and under for heating system is being built that uses brick just store the warmth the windows are made of smart glass that darkens when the sun shines keeping out about 90 percent of the heat in summer the house was built by construction company owner. for more than 25 years he's been building have to bring houses based on old designs but with the latest technology inside. it's a real challenge people used to build very differently centuries no one was

concerned with energy efficiency is cetera these days we have to work with significantly think a walls and accommodate very different things windows have to be fitted completely differently and it all has to be done so that it's not visible outside. the wooden skeleton it's constructed in a carpenter's workshop using only timber grown in europe. just as in olden times no nails are used. instead the beams are connected with joints secured with opec's in keeping with traditional methods. this is a joint that has been used by carpenters for centuries only wood is used. the advantage is that it expands in the same way when temperatures fluctuate and that's not the case if you use wood together with metal and that can cause damage in the long term. about 12 cubic metres of wood are needed to construct

a house with an area of 200 square meters if you place the timbers end to end they would stretch almost one kilometer it might sound like a lot but wood is a lot more sustainable than other conventional building materials like concrete and cement. today's new have to merge houses fit seamlessly into their surroundings. and if their historical counterparts are anything to go by they too will that centuries ahead of. buck in africa now we've got to turn on your people call him the father or you're you know this is one of the wheel was just 16 when you started tinkering with stuff and inventing things it is still watching him loves doing and he also loves to share his knowledge we've visited his innovation hard when you ideas get developed in watches and a lot of them are environmentally friendly.

where there's a will there's a way bennett has taken that proverb to heart legibly self-taught is a next but it's device thing mechanic well and the electrical devices this machine for example flattens inner tubes for a drip irrigation system in iraq one of. the point of an invention is that it has an obvious identity 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. 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 and nearby bogle. 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. to really walk 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 sun into power and install them and you're protecting the environment it was amazing in the prolific innovator shares his knowledge and passion with others a few years ago he co-founded the 20 social innovation center in the city of i will share here he and other staff members of our what shops and develop new ideas like using recycled materials to construct i will share project manager john is here every day he and bennett can we are regularly consult on technical issues. trending

in the social innovation center about 6 to empower the community to solve their own local challenges using local technology. 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. 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. family here 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 folding lead a normal iron sheeting of it the most difficult thing is the heating tubes but i

realize that used fluorescent bulbs can work if you paint them so i mean a workable way about. built from 2nd hand material to his solar water heater only course around $155.00 euros about half as much as a shop bought one thanks to his creativity and skilled organic kiwi has become a successful equal interpret new york as well as an adviser to other sparing innovators. fantastic ideas i wish we all could think of something simple and smart to protect our environment and also make the world a better place but now we move from one very clever man to a bunch of very tough women in zimbabwe yes you're right we're going to an all female training camp for the wildlife rangers their admissions criteria are strict but the employment chances for the women are good we looked in on them to see what

the training is like. this may look like basic training but in fact to this we men are competing to join a progressive conservation program they want to be part of the uk a shingle amanti porch in unit set up by anna strange and soldier turned environmental activist. sorry 2007 sorry we recruited the 1st 2 or armed all female ranger squads here in zimbabwe and the programs in our ground we've gone from looking after one reserve to being looking after 4 with a total of a 1000000 acres of the aca shingle which means the brave ones insure not the local language are willing to risk their lives to protect wildlife in zimbabwe or pond on the wildlife area but they are also united in a desire for independence and self-determination many of the women are victims of sexual assault and domestic violence someone abandoned by their families my husband used to abuse me years it was i can just simply say he was an abusive mean he was

very violent to me but i had no option i have to move from that plan and so this is the chance to turn to transforming the standard of life of our women most of the women in developing the ourselves and some of them to it financially independent all our catching the rangers come from communities near the area they patrol so they know the locals and also have a different way of connecting with them they are often more adept than their male counterparts at escalating potentially violent situations and showing people the importance of protecting wild animals and i think you know this i joke cliche of winning the hearts and minds it can only truly be won i mean guys the local community from everything off saying in 3 decades of law enforcement across 3 continents the best way to engage the local community and to get them on source is to work with the women this time 80 applicants plus their recruitment test and are

now starting their 6 months training during that time the women also train with rifles in case they do have to engage heavily armed poachers. since the establishment of the squad 3 years ago in the world less area elephant poaching has dropped by 80 percent in the former trophy hunting trust so far the acas shingle have arrested 115 porches using close combat techniques and without firing a single shot in $11.00 days to much the female ranges does saw as their peril man am i still am a woman and i jane did this project off i question that in 2007 i remember when we were in kenya we didn't have the training we were mixed to with the men and. i managed to challenge men in fiscal training even though i knew.

long run the pushups the sit ups. and the dregs so i think we're just this am because what they can to eq into and in some cases even better another factor in the women's favor is that there has not been a single incident of corruption there because shingle have been a success on various fronts and the model is now set to be expanded by 2025 its founder wants to have a 1000 female rangers in the field patrolling 20 packs. i hope this edition of the show has convinced she of the importance of caring for trees and maybe get you to rethink the use of firewood and i hope you found a mixture of topics as interesting as i did for now is goodbye. i just kept old territory ont it is a good life for me to hear incomparable i am saundra to know and i hope to have you

company once again next week for another amazing episode of africa till then do take care of yourself and goodbye.
