for power in traffic plummeted an entire continent into chaos and violence. this is the journey back into the history of slavery. our documentary series slavery routes starts march 9th on d w. a very warm welcome to this week's episode of africa i am sondra to nobody coming to from kampala here in uganda holland of africa where we do start by asking you did you know that there's not a match of foods that have disappeared from my dad's own most completely even though they're. so resistant environmental influences one such quote is now making

a comeback in mali and this is going to interest you hi sandra yes 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's championing climate change activism will tell you how and the women in zimbabwe training to be rangers in the fight poaching will 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 it had lots of disappeared the extremely small grain can be difficult to peel but it contains many more nutrients than say white rice in mali for instance many farmers are now switching back to this form of

millet as it 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 that harvesting for new a crop native to west africa a kind of military with small seeds and excellent properties it's one of the for. just growing crops in the wild it grows in dry climates and sandy soil even without irrigation for a long time phoney it was neglected but now more and more farmers are growing it again. is one of them. we have to take land degradation into account. is much in demand again now because

it helps protect the soil. so really when you. force after the phone you know has been cut the stems are left in the ground. and that helps to fertilize the soil. paramedic effective use it. because the grains are small processing them is very time consuming traditionally for new expression on straw mats than the seeds are mixed with sand and pounded 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 healthcare to us provided new machines that make it much easier to process the grains the one machine separates the grains from the stems 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 grain and still 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. he brought home slowly month one card runs a restaurant in the capital bamako. for new used to be reserved for special occasions and festivities but now it's becoming a daily staple. we watch the phone you're very thorough and we're 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 would look buffy is

mango chicken with 4 new. many guests come especially for that. phone you know is really the best food in mali created 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 noise 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. and. 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 teach our younger colleagues how to make calm passed. in order to facilitate the process they cover the pile with phony or straw. the phony 0 stems protect the compost from the sun. so there are many reasons why this ancient staple of grain is regaining popularity in mali 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 infect 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 important 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 aim to plant 100000000 hectares of new forest by 2030 knots an area almost 3 times the size of germany. so are you prepared to plant trees now the situation of forest is very serious as we've heard and one young climate change campaigner 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 block they use instead of having the tradition ok drinks aunt

parties she's also the money auction from the local and global leaders to come to the negative impacts of climate change we recently made to. get that many. you're going to. unum a good ways leading the sport to spec gainst climate change in the ugandan capital of kabul students taking to the streets. be a part of the global movement for ideas for future government action to curb climate change. there is a my purpose is that we are young people and we are facing 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 you turn 15 last year she didn't want to kick or her

party is did she decided to celebrate her birthday by planting 200 trees. you know gust she launched a tree to come pain 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 planet. of. cheese. with. many ugandans. 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 the trees in nature reserves she has also convinced some land owners. to plant trees or private land if i had planted. the forest. plants. to increase. the whole forest. despite some resistance more and more students in uganda joining. every friday. to strike for climate justice government action against the global climate crisis. become pinas gone viral on social media i want our government to know that this climate action is real and it's needed you know oh

this is taking place so i wonder gummy also get to see what you got through and they also take but understood but to various possibilities. also doesn't shy away her hands dirty she. used to late victoria which is not far from high school. together they collected plastic waste from its shores and encouraged locals to do the same. children 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 don't do this without practicing what you preach when they 1st started the lecture cleanups will find a lot of rubbish because it was there and everyone would just throw rubbish in the legs but since they started seeing us cleaning their legs people have now a very good chance to us when they see as their leg we are going to clean their leg

now and they're being called pride to you they know that it's non-trade for the revelation that. even with some of the rubbish on the lake cleaned up you know i'm going to face his huge challenges. fortunately she can count on her family to support her how far they've been peaceful the seedlings his fist public criticism for his daughter's activism but he say's that she would rather see her own districts fighting for a good cause than staying silent when the planet needs the help. so these are no houses have been built in europe for hundreds of years the surprising thing is that these houses are not only places but also very sustainable that is why some villages in germany are starting to adopt the style of once again let's take a look at one of these new but own fashion 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 timber houses not even one year old yet it was built using the old methods have timbered inside and outside for owner nor bought off money it was important to have a low energy home equipped with the latest technology but the roof to is based on a historical design. it's a so-called cold roof which is well ventilated this is. that's an old building technique in the sense that in the past they were only called roos 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 a fuel cell supplies the building with electricity a solar thermal system provides warm water on the ground floor and underfloor 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 heiko schultz 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 is 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 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 $200.00 square metres 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 have centuries ahead of them. but in africa now we've got to count on your people call him the father of your you know they should funded the wheel was just 16 when you started tinkering with stuff and inventing things it's been still watching not doing more and he also loves to share his knowledge we visited new 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 his and next but that's device thing mechanic well and the electrical devices this machine for example flattens inner tubes for a drip irrigation system you look at one of. the point of an invention is that it has an obvious benefit i realized that the environment has been neglected. even though it's so important to human life i will so i decided to focus on technology that works well into your home. before your technology. to your mother get. at home he installed this windmill to produce energy. it powers his homemade washing machine and pumps the water will reach from a nearby bobble. 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 or you and the sun is free is the power of nature you don't have to pay anything all you need to do is guess the parts that converts sand into power and install them and you're protecting the environment it was amazing you did prolific innovators 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 a wheelchair project manager john is here every day he and bernard can we are regularly consult on technical issues. 20 is

a social innovation center about 6 to empower the community to solve their own local challenges using local authorities. 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 in . many of the contracts come from famines asking for example if it might be possible to construct a machine that plan. it's a sibling directly in the soil planted an average inventors try to develop effective solutions some customers stop by his home to see his machinery in action many interested in his solar powered water heater if you give up. the farm where he has the most important part of the tubes they are 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 of it the most difficult thing is the heating tubes but i

realize that you used fluorescent bulbs can work if you paint them signing up work but what 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 skill on the planet has become a successful equal interpret 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 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 these men are competing to join a progressive conservation program they want to be part of the uk a shingle and empty porch in units set up by an australian soldier turned environmental activist sorry 2007 sorry we recruited the 1st 2 or armed or 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 vaca shingle which means the british ones in china the local language are willing to risk their lives to protect wildlife in zimbabwe a point on the wildlife area but they're 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 use you as 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 family and so this is the 1st to tell is transforming the standard of life of all women most of the women in developing the ourselves and some of them that it financially independent all 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 collating potentially violent situations and showing people the importance of protecting wild animals and i think. this i jog cliche of winning the hearts and minds it can only truly be won when we engage the local community from everything off saying and through 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 passed 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 porters since the establishment of the squad 3 years ago in the wildlife area elephant poaching has dropped by 80 percent in the former trophy hunting trust so far the aca shingle have arrested 115 porches using close techniques and without firing a single shot in 11 days to match the female rangers does saw as their peril main aim was to me and the world and i jane did this project of high pressure that in 2007 i remember when we were kenya we did their training where mixed with the men and. i minister to challenge men in fiscal training even in. long run the sit ups.

and the dregs so i think we're just the same 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 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 good but. i just kept old surgery until it is a good buy for me to hear incompetent saunter to no avail and i hope to have your

company once again next week for another amazing episode of africa till then do take care of yourself and goodbye don't. know.
