tv Eco-at- Africa - The Environment Magazine Deutsche Welle November 18, 2017 3:30pm-4:01pm CET
magazine my name is now out. and i'm here in lagos nigeria and happy that you have joined us this week for some exciting stories my colleagues sounds it. and i'm sharing the money right from the heart of nairobi city in this very beautiful and green park welcome to today's show where we have new and fresh environmental topics from around africa and europe. on today's show we have a look at bio diesel made out of west five pound in syria us to see how people in uganda are using the backyard of their school for farming. and to learn how to make terra cotta a very fun time that's good for the environment. when we think of farming many times we never really considered the different components and how they could work together i mean we should have in port harcourt actually decided to look at how to
ensure that the entire component of the farm animal husbandry farming and all of that can depend on each other and help each other to grow so that the waste from one is used as fertilizer or is used as feed for the other let's go to rivers state . and see how this initiative is working on the plans to duplicate it to other farmstead. at first glance it looks like at all the reform bill the shanghai rivers initiative is far from its land covering an area of over three hundred hectares is cultivated using shanghai principles in other words crop production husbandry bio energy and fishing all depend on each other. circle economy tommy judger
coordinates the farm is the zero emission research initiative and the zero with system is a system that works on race. recycling of byproducts and wist products so what you have from one production center that's a whist the twist is being channeled to an auto production center where it is being put into effective and efficient use this on my farm has three important branches first this husbandry also teaches cattle pigs donkeys poultry and even snails then there's a fish farm featuring a hatchery and several homes and of course crop production. the aim is to link the different branches and all the nies them in a sustainable and environmentally friendly way nothing is considered waste. the
money or from the chickens is used to fertilize the fields and the waste water from the fish ponds it's use for irrigation killed by philosophy for hiv it's all forms of chemical fertilizers and pesticides which are considered harmful they system here is a system that with a lot of cultural practices one what the of mention in is the motion we use the dry grass is there more which will suppress the wheat so you do not you do not need to go bring they have decided to to spray here the farm also has installed a by a gas plant where crop residue and organic waste are collected when the material decomposes it produces methane gas it's odorless and can be used for good king. will try as much as possible not to with some of these byproducts effluent is
a byproduct now this effort but you know you are seeing itself is useful we haven't but you know in this farm seps us our liquid organic fertilizer. agriculture makes up over half of nigeria's g.d.p. conventional farming methods can harm the environment and the soil and in some cases even decrease yields in the long run the organic system protects the soil and increases yields gradually. why not just looking at the they would have to learn we are also looking at the environment because this coming. pesticides the insecticides they have besides decides all of them. because in today's environment some of them over the period that becomes the becomes a buildup did build up and then you can even. if you trip down down down to the
far the water and then pollute the water. the farm also serves as a training center where young people can learn about sustainable production techniques it's hope that this will help spread the ideals and the values associated with the shanghai system and eventually allow sustainable businesses throughout africa to thrive as the world's population grows the quality of the soil is rapidly decreasing approximately thirty percent of the globe's lawn affected and around three point two billion people depend on this land the area most affected is the region south of the sorrow what's causing all of this shallow well for example soil loss but also climate change and industrial agriculture which damages the soil with artificial fertilizers and heavy machinery but there are ways
to stop this process and what unquote cures six oil the solution is a very special type of that's called a teleprompter and can be made anywhere in the world we had a look in germany. it's harvest time in this experimental garden entrepreneur. is pleased with the yield because of these crops haven't been watered or artificially fertilized for ten years. they've been kept alive soley through natural rainfall and yet they're thriving the secret behind this apparent miracle is a layer of tear up on the ground the highly fertile soil mixture is based on an old indigenous formula from the amazon region the watsons of the roots need more than just moisture they transport the nutrients and need very porous earth if there's not enough air down there and because the soil is too compressed or dense they
don't grow well with taro prater the soil is loose area and moist and it contains nutrients and beneficial microorganisms. tara crater portuguese for black earth can be made almost anywhere in the world. here it's makes from locally sourced materials in this village in the frankfurt region it's made with mown grass dried leaves the remains of mushroom cultivation and manure the ingredients are then combined with a special mixture of charcoal bacteria and fungus this is covered and stored for four weeks to allow the mixture to ferment converting the organic waste into fertile soil. the claim that lavalas that if we can use a wide range of biomass types for our charcoal production and it doesn't have to be worked on we can also use things like straw or leftovers from the harvest even bones clean a whole array of carbon containing products can be turned into high grade charcoal
and this charcoal is the basic ingredient of tara prater. a look into the microscope shows why charcoal is highly porous so it can store water and nutrients the pores offer a breeding ground for microorganisms which help the plants to absorb the nutrients others transform plant remains into humus and bind carbon in the soil helping to protect the climate as well then one of the other what we'll have to feed over nine billion people by twenty fifty that means we'll have to treat the soil differently tara prater after is us the chance to at least help farmers conserve and prove their soil at a locally sustainable level. these agricultural experts from morocco share the same goals agriculture plays a fundamental role where they come from. here they can see first hand how soil improvement functions in detail that helps them find solutions for their own
environmental problems. in general our main problem is the intensification of agriculture because it also leaves us with fewer organic waste products for the money as you know if they want to use the charcoal rich terror in morocco as well it's. also into them. once the ground is contaminated or depleted it takes many years to recover so we have to find a solution to tackle that problem. and the soil we've been shown here. is an excellent solution. these riesling vines when growing well anymore many of them were small and spindly. the ground was dry and depleted so the vintner added terra prater to the soil.
this thing is we're here in an area where vineyards have existed for almost two thousand years without crop rotation in principle an extensive period of monoculture. that will definitely leave some areas a bit worn out the soil has to be reactivated we can't continue like this for another two thousand years. the initial results are very promising this ancient farming technique clearly has a bright future. when i had to zimbabwe where we met with more than i she has led to produce an innovation that will keep the environment clear by cutting down on energy consumption it's a bug that keeps your food warm and it's made from crush see how this inventive lady and her family from zimbabwe are doing their bit for the environment.
did you know you can save energy by cooking in a temperature bag. stara phone litter has become a huge problem worldwide. clean up is expensive and once broken up into pieces the plastic can clog the digestive systems of animals. in zimbabwe has found a way to help a temperature bag. if you use a styrofoam granules insulation. produces the bags in her family business. here's how it works you cook your food for a few minutes then put the part in the back the temperature back takes over until the food is ready using the traps heat.
depending on this the bags cost between fifteen and forty u.s. dollars in the end you save both money and energy. and joy. like that. if you are also doing your best to tell us about it. this is our website or send us a tweet. hash tag doing more then we hear your stories. when i got to the ugandan capital kampala where there's a lack of land to grow crops like in many other cities around the world people are starting to do our been farming now even schools are getting in on the act they are encouraging the vast students to use the limited space in school yards for farming the lambing important new lessons it's also
a lot of our reporters so a jew luciferian is harvesting spinach and mangold chooses to do to a high school in the ugandan capital kampala. linked to the school is an area of land just a hundred square meters in size where the students can grow vegetables angel uses old plastic containers for plant pots as a way of recycling waste so most of these and then they do not become poised so instead old either buying them and producing small country. or maybe buying them in the ground that has been destroyed the show that museums cutting cycle them and use them to grow crops which. angel and her classmates mostly grow cabbage spinach and spring on. the boarding school of the outskirts of compound is a pioneer in urban farming and encourages students to take their schools home with
them. got the lessons take place once a week. find a placement if israel fight. the charges all consumed at screen also to members of the public on visits and the head teacher says the project is a huge success maybe ninety percent of the girls i have raised in the urban area and this is critical for us because they have to be active somebody on money in. a small place and money regardless of how small a place can be. the initiative is paying off angel has even inspired the parents to grow vegetables which. they retired so they have enough time to take care of the plants. because it's days if i'm preparing my breakfast i pick if you're if you're leaves and then i cut and put in my ford. a lot well you find that
every day i spend our own toso than three cellar that we're very good like if you have them around home. a lot. of farming is still in its infancy in uganda. the students hope to get financial support from the government as the initiative is rolled out to other schools the minister of education is already full of praise for the project. feeding the children would not become a problem saving the environment would be very important i mean it would be very we would be done because we have seen the way they are using the policing and the old teens and so on so we should not be polluting the environment there will be a two lazing those very things the users that is on the verandah. whatever they don't consume the students sell on visiting days one large cabbage and the school around one us dollar for monies paid together and used to help pay for food at
boarding school on a larger scale urban farming has the potential cycle food insecurity and unemployment but for the students growing their own crops is first and foremost a lot of fun. if you think of england what's the typical dish that first comes to your mind when i think of fish and chips and preparing this national dish requires quite a bit of cooking oil in london flat bars and restaurants the use of millions of litters of cooking oil every year and most of that used oil ends up in the sewer system which clone things up and cause a serious blockage of how disgusting right empty oh most definitely sharon or believe it or not these so-called fat birds can be used as a resource now a british company is turning them into green bio diesel let's have
a look at how they're doing it. if you're going to venture down into london so as you don't want to be too squeamish sewage for millions of homes flows through these tunnels restaurants and snack bars also flush millions of liters of cooking oil down the city's drains every year this discarded fact has led to a festering problem in the sewage system liquid grease congeals into a tough slimy mass these so-called fat burks can cause serious blockages british company arjun energy is transforming this waste fat into bio diesel dickon pozen it is the company's director of corporate affairs is the only one in the world that can handle such degraded horrible smelly raw materials including some birds the fire dug out of sewers and out of water treatment works the flattened scum that comes out of that we can deal with that we can turn it into an
oil and put it through the body's a process bio diesel can be produced from a range of oil based materials with most of the world's supply made from soybean oil producing bio diesel from waste fat isn't new but arjun says their facility can transform even the most rotten of raw materials like animal fat food waste and sewer grease into bio diesel urgent sourcing manager heather sweyn bank is responsible for gathering the putrid wrong material. my will with an ounce of energy is actually to go out there speaks the words companies to make money factories and different people who are putting this stuff down. and bringing his watch and you to make biodiesel ansermet so i guess you call me a fact hunt. and this is how it works first the sewer grease is saved and filtered to remove any solid materials. in a second stage another system renewed the water. then the
oil is processed through a chemical reaction and turned into raw bio diesel after cleaning the bio diesel it's blended with conventional diesel and supplied to bus companies around the country there's a sustainable fuel this facility near liverpool cost eighty five million euros but arjun says it was worth it the carbon savings that we get out of this plant alone is just under a quarter of a million tons of carbon every year which is the same as one hundred twenty thousand cars off the road in. the company believes there's enough fat in britain's to as to keep them in ready supply the hope is that in the long run the bio diesel produced from london's fats oils and grease could be used to power buses in the capital and chances are good that the plan might work a few years ago the biggest ever fat bird was found in the sewage it weighs about
one hundred thirty tonnes the company estimates that could provide enough raw material for up to ten thousand liters of bio diesel. now let's head to the children national park in botswana to visit a special wildlife project to always come to the area to see animals but even left unprotected the wildlife will die out and so world tourism luckily there's a large in the park that is more than just a police officer to stay it's a pound in were billeted on its staff members how was rational policing the hard for the ross let's go take a look at. the truby river in northern botswana farms the country's natural border with namibia while fishing and agriculture dominate on the namibian side botswana has put its side of the river under protection but it was fifty years ago and my child be botswana's first national park. early morning
is perfect for watching wildlife. in my life and that's why you know. seventy thousand jobs in botswana depend on the tourists to visit the country's wildlife reserves but for gold the much it easy working as a park ranger is much more than just a way to earn money. together with the i'm lost means everything in means everything to what i've just told is so close everything is the most important thing we have to level and you have to protect the environment and i'm happy to be one of those people that do that in our country. the high pitched whine of an electric motor. this game the year is one of the first electric safari vehicles on the african continent and besides he cars show became large also boasts a fleet of silent solar powered boats and besides that it's also managed
to cut down on ninety five percent of its waste and garbage. running it tourism and focusing on it. is going to be paramount you're crevel of these days are becoming also more responsible and they would like to make sure that if they do go on holiday that they do support sustainable holiday destinations and operators. with two million visitors every year what's one as tourist industry ranks second after diamond mining conservationists around the world commend its complete ban on hunting and fierce stance against poaching across africa hunting and the growing human population of forcing wildlife out of their natural habitats many of the most fabled species have been driven to the brink of extinction conservationist robert sutcliffe who collaborates with the
chubby game large is worried. even in botswana road construction poses a serious threat to wildlife. one of the main reasons is habitat loss. i don't have elements around a lot of there is being. and. there is no plan for farming and i'm developing like the same cosigning and pushing these animals out of the areas where they have it. in twenty twelve chhobi river and its national park became the center of the coven goes on b.c. trans from t. a conservation area this is the home of one quarter of the global population of endangered african wild dogs. it's africa's largest reserve and spans five countries the aim to enable animals to migrate naturally and freely.
the effort is paid off while giraffe numbers are dwindling in other parts of africa here bestival numerous. that it's so important that we work to try to conserve to this population that this could be as the stronghold for forward here and it's amazing to see them moving into zimbabwe moving back into botswana and. there's no barrier to that than the one state which is it's wonderful to see. that roughly five percent of g.d.p. eco tourism is still in its early stages in botswana but the sector is growing fast providing a steadily increasing contribution to the wellbeing of the country and its people. what inspiring luck less of that a lot more projects like this well that's it for this edition of africa the environment a magazine my name is thank you so much for watching and see you again next week.
