know that there's not a natural foods that have disappeared from my dad's almost completely even though they're. so resistant and vironment influences one such school 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 to fight poaching we'll give you the details. the formula green has grown in africa west africa for around 5000 years and we've more and more areas being given over to rice had lots of disappeared the extremely small grain can be

difficult to peel but it contains many more new trends than say why bryce in mali for instance many farmers are now switching back to this form of millet 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 a district in the central eastern region of mali near the border of book enough so that harvesting for neo across native to west africa a kind of millet with small seeds and excellent properties it's one of the fall. 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 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 effectively. because the grains are small processing them is very time consuming traditionally for newest threshed on straw mats then 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 help better 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 grain and still our hands get 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 bread and also beer. ibrahim slowly among 20 car runs a restaurant in the capital bom a call. for new used to be reserved for special occasions and festivities but now it's becoming a daily staple. we wash the bone you're very thorough and we've prepared in such a way that people can eat it at any time. we served with 2 kinds of sources like

a peanut sauce. or a tomato sauce. but the most popular dish on the menu were the buffy is mango chicken with for you. 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 nothing in 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 in the p.l.t. 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 photo stems protect the compost from the sun. so there are many reasons why this ancient staple of grain is regaining popularity in mali but a man 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 in fact 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 this 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 brief forestation projects. 27 african countries aim 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 course 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 lennon haunt the ideal planting trees

on black days instead of having the tradition ok drinks and parties she's also the money auction from the knuckle on the global need is to come to the negative impacts of climate change we recently made to. you that i'm a big. you're gonna get me. you know i'm a good ways leading the spro to start gainst climate change in the ugandan coffee to have compounds students taking to the streets to be a part of the global movement for ideas for future government action to curb climate change. there is a my practice is that we are young people and we're 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 i'm going to turn 50 in last year she didn't want to kick or to party instead she decided to celebrate her birthday by planting 200 trees. she launched a tree to compete with new trees which go to a lot of attention. 3000 trees. given back to the.

that is suitable for a forest and much of the space is used. once the government. the trees in nature resolves. to plant trees. that would be quite a big furnace to buy now and this we weren't doing if someone plants. 10 crees meaning mom within 10 yards the whole forest in your view window would be back in shape again. despite some resistance more and more students in uganda i joining tours every friday and i'm going to lose her boarding school to strike for climate justice demanding government action against the global climate

crisis the campaign has gone viral on social media i want our 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 get a special group and they also take but under such a budget their responsibilities. are also doesn't shy away of getting her hands dirty she actually went to lake victoria which is not far from high school. together they collected plastic waste from its shores 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 business with practicing what you preach when they 1st started their like shockley know we're following a lot of rubbish because it was a market. and everyone would just throw our ambition their legs but since they

started seeing us cleaning their legs people have no even to us when they see as their leg we are going to clean their leg now and there they're being called part 2 they know that it's none trade for the rubbish and. even with some of the rubbish on the lake cleaned up you know i'm good. faces 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 daughters activism but he sees that he would rather see her own distributes fighting for a good cause than staying silent when the planet needs the help. so this and all but houses have been built in europe for hundreds of years the surprising thing is that these houses are not only pretty but also very sustainable

that's why some feel doesn't somebody on something to adopt this time 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 loan that made sense wood sand and clay were all freely available materials. this have timber 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 to 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 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 of fuel cells 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. 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 and cetera these days we have to work with significantly thicker 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 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 have centuries ahead of them. but in africa now we've got to turn on your people call him the father of your innovation fund that he will want just the 16 men who started tinkering with stuff are inventing things it's going to was he loves doing and he also loves to share his knowledge we visited his innovation hard

when you ideas developed in watches and a lot of them are environmentally friendly. where there's a will there's a way bernard has taken that proverb to heart largely self-taught he's an expert at devising mechanic well and the electrical devices this machine for example flattens inner tubes for a drip irrigation system walking a fine. 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. for the technology. to your mother here at home he installed this windmill to produce energy. it powers his homemade washing machine and pumps the water will

reach from a nearby borehole. 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. 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 can fight 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 as a few years ago he co-founded the turn this 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. trending in the social innovation center about 6 from the community to solve their own local challenges using local technology. the community can feel that we don't have we don't import this knowledge or use things from outside because of the things that we have we use them at home that we find in the local shops that can help us in. 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. 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 100 stores this one has used a metal folding 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 with workable way about built from secondhand material his son a water heater only course around 155 euros about half as much as a shop bought one when it comes to his creativity and skills on the planet has become a successful equal interpret near as well as an adviser to other sparing innovators . one time stick 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 to this we men are competing to join a progressive conservation program they want to be part of the uk a shingle and anti poaching unit set up by an australian soldier turned environmental activist. sorry 2007 sorry we recruited the 1st 2 or armed all female writers 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 brigands ensure the local language are willing to risk their lives to protect wildlife in zimbabwe a point 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 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 plan and so this is the chance to tell is transforming the standard of life of our women most of the women in developing the ourselves and some of them that it financially independent all approaching the ranges 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. potentially violent situations and showing people the importance of protecting wild animals and i think. this i joke cliche of winning the hearts and minds it can only truly be won 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 a woman this time 80 applicants past 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 form a trophy hunting trust so far the aca shingo have arrested 115 porches using close techniques and without firing a single shot anyone who wonders 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 in 2007 to. remember when we were pena we

did their training we were mixed in with the men and. i minister to challenge men in fiscal training even in. long run the push up the sit ups. and the dregs so i think we're just this sam 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

territory and it is a good bye for me to hear incompetent. 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. dot.
