is the 77 percent the platform for africa. please use and share idea you know, or this channel. we are not afraid to happen. delicate because population is growing. and young people clearly have the solution. the future belongs to the 77 percent every weekend on d w. d. ah, we all need foods to leave, but millions of people also produce foods to make a living. here in africa,

i recall. gotcha. is still the most important economic activity, i think provides employment to up to 2 thirds of the continents population. welcome to echo africa. i'm crease a lamps. and i am sandra to interview they on these special edition of our program . we are focusing on rethinking agriculture, and we'll learn about how we can fund more sustainably and keep the world fed. here is a quick look at what is coming up. we see how a former in germany is combating to wait agriculture. we're also he about a fruit not asked for the black good of side for us and we learn how tiny helpless of what you talk about a pesky plant in south africa. we start today shall, righty. in uganda. here in the country, we produce

a wide range of agriculture products like con, suite for the toes, so gum, coffee, and tea, to name just a few. but just how those quotes are farmed can have a big effect on the hills of the soil, as well as the harvest. as we'll see in our 1st story. with these numbers have never looked so closely at earth water. does anybody in my nutrient reach till i have always regarded these worms as dangerous? i would not have them in my garden younger whenever i see them, i get rid of them all. colace you. what was it? the one you saw was a yellow. but these worms click and hold and roll them to compose, plant debris, with their excrement. they enriched the soil to pass on this knowledge, that biologists and fond of an angio for sustainable land use. alita ben decade gives regular training courses like this one this morning. ah,

we are learning about van composting. how can we try to amend our sales using radio with los they're capable of producing for us? those soil amendments the likes of one castings. fertilizer can also be obtained from drain waste. the liquid is then simply added to water, useful aggregation. it's a very cheap and environmentally friendly fertilizer. in his training sessions, alita, ben decker explains how elements of nature work in symbiosis. each plant and animal has an important role to play. when look at the food forest system, we have the shot once. then you could see we have the total once, and then we have that the under story plants. that means that each one is contributing to each other, where we have the, the natural hedgerow of the vet,

eva, it collects and also acts as a hobby ticket for small essex that could contribute to beneficial insects. that could deter, or that could reduce the population of the dangerous pests. the farmers need to know how even minor human interventions can upset nature's balance. experts believe it can, we connect the systems and make them more vulnerable to climate. extremes by diversity in the fields is also better for humans. studies by units of, for example, showed that small farmers with few cropped varieties in the fields often suffer from poor nutrition. sciences from uganda has confirmed us in african context. you realize that also in the region. yeah. in total people eat what they produce at the person is producing one bus and 5 acres. but on that 5 acres, what else is there?

do you have the legends that you have been on the same farm? do you have animals on the same farm? you have lentils on this, and you have vegetables on them? if you don't about diversity, we don't about day vested when the fun, which is actually supposed to translate into day vested on the plate. and the day vested in the market. and the cool farmers learn why it's important to leave trees in the fields or to plant new ones. pharma, a ruby has implemented this idea and planted jack fruit trees among his vegetable crops. emmy, tina utica, into equal anger. what do you mean? i have to have the trees because their crops, which grow well in shaylee park. this trees are just windbreaker with. yeah, i will use all the class, all sorts of herbal medicine you will to treat my family against illnesses like office at the gate were like she was going to be that got into a song that got ali to been decades rained around 200 farmers in the last 3 years,

he has also founded a savings group, offering micro credit to members. some can even trade to produce in the community. they ascertain people or may not be interested into funding. but using such avenues, it becomes something that can spark off. someone is attention towards farming and then also towards being environmental cautious. alita ben j as convinced our bio diversity in fields is better for everyone. both of people's health and for nature. whoa want, uninspiring example, modern agriculture. annex reporter comes from europe. you may never part of the curb tree, but it is an undemanding plant and also goes in the joint regions. the fruit is edible, but not all farmers know what they're good for. in cyprus, i ang man, is following in his grandfather's footstool and hovered. the fit was his met in 2

different products. and it turns out that given all traditions alive, is definitely worth while. every year thiel finance cristo helps out with the harvest. his family taught him everything he knows about the care of tree. the ponds are ground into a powder that's a popular substitute for cocoa. it's used as a sweetener to and also as a natural adhesive who sto is studying financing, so he knows a lot about markets for decades. karen prices have been low, $0.35 per kilo a, the middle, her pure. it doesn't matter because of the war and ukraine, the price of a kilos. kara reached 85 cents this year and is expected to reach one euro per kilowatt. diaz dies. anyone who harvested care of this year will have an enormous

income because you don't spend money on growing care of. you just harvested from trees and transported to mills heidelberg when guns got dikes will are cultivating carob supposedly 0 expenses and, and it's profitable not got. i don't get of those. karen trees have been cultivated on cyprus for some 3000 years. many local families with their roots on the island own care and plantations, like george potty. he's the way that this said, please here, which is how nearly all pop out true checked us. we are planted by my grandfather. we'll go buck more than $100.00. v as a call. once the pants have been harvested, the farmer takes them to the mill in the coastal town of z, he for centuries, karen ponce known locally as black gold. we're one of cypress is main exports in the last century. cypress was the world's 3rd largest care and producer. these days

karen cultivation is no longer as lucrative as it once was. but many families have kept up the tradition. i am the last generation. my children have other jobs. they are not. so if they don't mind that body, i got your i crops because they don't pay. but now carol is making a comeback. demand has risen in recent years, not least because the flower from the pod is increasingly used in vague and cuisine, as well as various diets. the plant is versatile and can be used in its entirety from the fruit to the seeds. in an o, utah in the south of the island, karen products are ubiquitous and a stable at the local market. the government has become more aware of their value to the agriculture minister plans to boost karen production on the island

level, middle about inability. she wanted to give me the blue william cara production is very important for cyprus, because it doesn't mean much insecticide. fertilizer and water isn't at all yet. lovely books give you the money yet. this is important in terms of climate change. need someone to call to be soon as possible. just wanted to go over the appleton. it's also important because you can create a huge range of products from the cara p up. but i'd be not a militia was more care um can be found in products such as candy syrup and bank goods. and it could, once again become apprised. export and of demand continues to grow. more care of trees will be planted. reviving karen cultivation would be an investment in sustainable farming. it was profitable in the past and could be possible in the future thing in europe and talking about an ecosystem that is a climate wonder pit lawns are absolutely amazing based or a thin amounts of coupling india soil. by the way,

the biggest midland in africa is in the dear sea. it is the size of england and wells combined and stores almost $20000000.00 tons of counseling. well, the problem is sandra. we are destroying pit lance, at a crazy rate. and mostly just to extract resources or plant crops. but that releases enormous amount of c o 2, the famous there is no need. we can do both save one of the most effective carbon storage systems in the world and fund them at the same time. let's take a look. ah, good to find out how that supposed to work. we came here a farm in germany's east. all of this used to be conventional so dry farmland, but in 2015 it got turned back into pete lance wet, farmland. and this is sebastian pitney,

the guy who's in charge of it all. he re where it is $107.00, hector is completely pity, mainly grows marsh crosses to sell us horse feed, but operating in the wet new need wealth, special equipment. it's a former snow chair that used to groom ski runs, it had to be completely rebuilt. we kept mostly, the chains had to be completely replaced out of an a mountain. you had these aluminum bars which are quite aggressive, allowing you to drive up the mountain natural father. we want to work as gently as possible on the ground. so we installed wide steel struts instead of why the starting the alpha to keep his fields whit pitifully needed to completely close down his drainage system that runs through his fields. the solution was quite simple. we barricaded the gates with wood, easy and effective, plus, extremely helpful in dry somers. to the, in the, on the viet tom, it,

in years like we're having now with this drought is this water here is worth its weight in gold as possible. see it. so if we retain the water here over a large area, then everyone benefits from n lafond lamb, because in the end, the water moves around to the that is also an important function of the bogs. the thing is as all, not only carbon storage, but also as a water reservoir, a quick quote you quote of spite over and over as far as like, despite the enormous re wedding efforts, the water level here varies a lot from 50 centimeters above ground to 60 centimeters below, during dry summers. this can still lead to c o. 2 emissions in pete lens. but how did the glance trap carbon in the 1st place? so we just took this out of the ground. and you just grip this piece of earth and squeeze it against the orange waters calling all that

and that's basically what makes caitlin's. so climate friendly the water because below me are thousands of tons of that plant. but because people are wet, they don't decompose the microorganisms who usually do that, don't have enough oxygen to take care of that. so the carbon remains in the soil. and when all this dries up, the plants suddenly decompose much faster. and the oxygen in the air attaches to the carbon in the soil and you get c o 2. and the scale is mind blowing between 5 and 10 percent of all men made greenhouse gas emissions come from damaged pete lands. this new approach of combining agriculture with pete land meadows is called polluted culture. and this also has advantages in terms of productivity loiter in this way. i ensure that the degradation of my pete land is as close to 0

as possible the summit, meaning i still have an area on which i can continue farming. my la photo is in the other advantage is water attention. there is mean, even in the dry isd years if i can still get a decent harvest inflation wall. one of the fountain cup and hay isn't the only thing you can produce on pete lens. alternatives include common, read, and bull rush, which is also grown in these tots here at the university of glass vase, where scientists try to find out everything about growing stuff in wetlands. here they scan roots and measure every millimeter of plant growth with these funky machines. they have x ray vision, but wouldn't it be better environmentally if we'd give pete lens completely back to nature and not found them the long? well, as long as routes are being produced and the more wedding this

a new piece should build up again as mystic most. and the thing is the water level is if the mores where much it's good for the climate. whether we then farm it or not, it's just a question of what we want to do with it. fog of us when viewed and so you don't need to revert completely to nature to reap benefits from the peak loans. a you case study looked at the climate effects of different water levels in pate lands, raising the water level in degraded pete lens world wide by a few centimeters, would already reduce emissions by 65 percent. that represents 1.3 percent of global c o. 2 emissions sebastian pity also owns 35 water buffaloes. they mature slowly, but every once in a while he slaughters them and sells the meat. he's been doing this for a fair while now. doesn't pay off compared to intensive conventional farming. although i'm from a purely financial perspective. no. oh,

but when i think of it as an investment, the future then yes. because i am showing that the land was to be productive in 20 or 30 years. time rises. yon not to watch off of them, but not hotly, but compared to the revenues of intensive crop farming, the current cost of re wedding pete lens and buying new machinery. most farmers will be better off financially if they stick with intensive families. away to make polluted culture more profitable would be that government stop paying for the climate benefits that re wetted pete loans provide. this could help get more farmers interested in the idea of polluted culture. and it's environmental benefits. something quite helpful when you know that 300000 square kilometers of crop land need re wedding globally. that's the size of italy stain on the topic of rethinking agriculture. our next report comes from an area of

ivory coast, also struggling with severe some farmers there and are banding together to protect their fields from winged and unpredictable weather conditions. here is the seeks doing your bits, blue, ha! oh, how can we protect fields that are exposed to both drought and heavy rain in northern ivory coast farmers used to simple methods the small stone wools that building across their fields retain water. the walls stay run parallel, but snake back and forth. they use a level not to check whether the ground is even but to find out which way the land is sloping. the stones and then laid said that they will catch the water runoff.

sat paramedic fair to the dealers that allows us to fertilize the soil because the compost takes put his shot and the ditches. we have already dug. if you can fill up with water, easy to set up li. oh, they have all say planted trees to act as wind brakes. they are regularly pruned to keep them in check, lays out of grown up lack did that my did. the trees we planted help to shield the soil from the wind. the small walls we are building to distribute to run off. there's your data silly loss so that the water doesn't wash away the soil and create deep channels, which would make the land useless in the long run to sell a lot there. so ah, the farmers and al feeling more connected to they realize they can only protect their fields together. oh man, how about you? if you are also doing your bit, tell us about it, visit our website, or send us

a tweet. patch tag doing your bit. we share your stories in today's mode and interconnected world agriculture. as a big business must the force have probably eaten food that our grandparents never even heard of or had the opportunity to taste. but as a sheep proved use and goods around the world, sometimes other plants and animals go along for the ride. and in some cases, that can cause huge problems in their new homes. as we'll see in our next report from south africa. ah, a green mass where open water should be for decades. the problem now to base put down in northern south africa has been growing exponentially. the lake is overgrown with water hyacinth, a plant from south america. now clogging bodies of water throughout africa,

the invasive plant grows extremely fast. the ecological consequences are dramatic, combating the plant has been difficult despite intense research. high is one of the world's morris to am problematic classic liter. it's been present on how to pittsburgh dam since the 19 seventy's, and it's a massive problem. and they've tried to remove it manually through herbicide applications. but it's still a massive problem am and because it can cover up to 40 percent of the damn survey researchers in south africa have been trying to control the invasive planned for years well sealed off from the environment. scientists are looking for the water hyacinth natural enemies. and they've made a big find that's only 4 millimeters in size. the inconspicuous water hyacinth

plant hopper is also a native of south america. the insect reproduce just as rapidly as the water hyacinth. and the little guys have a big appetite. one of the major concerns we haven't, biological control is that in sick that me release could feed another plant species . so we mitigate that in this facility by testing this candidate insert on various plants species including native species and crop plants. and we need to do this testing to make sure that the insects that we released odd will be co host specific . this testing is very thorough and sometimes can take years. it's important for this because once it is roneesh, recontact him back. the tests for the water hyacinth plant hopper are finally complete. the bugs are now being collected and packed for transport. together with a leaf of their favorite food, they're on their way to the heart to be sport dam. rosalie smith of the center for

biological control sees to it herself that the insects reached their destination. the denser the water hyacinth scroll, the better it is for their little enemy. they can multiply here quickly. oh i preach with releasing the plans. i am using them as a green herbicide sir as many as releases as possible early in the summer. i that allows their populations to build a cookie and that also just allows them to damage the. * plans as soon as possible, so that the plans try and expand their growth over the damn water high is since form dense mats that drift across the lake. when they collide, their underwater roots become entangled and block out any light. gradually, a huge dense carpet of plans forms. they can completely over gro bay areas,

which is not only an ecological problem, but in economic one too many people at the damn live from tourism. each year columns of workers removed the plants from the water with long rakes. it's a slow and laborious process that only works on smaller waters in huge areas like this though, the tiny helpers have to step in. the traces of their work can be seen on the water hyacinths leaves. holes and brown areas testify to the success of the organic pest control. the nibbled on and dead plans dropped to the ground and slowly decompose under water. you can also see them from space. within 2 years, the growth on the dam has decreased from 40 to just 5 percent. this is a site to where we did frequence inundate of releases of the plans hopper am. and

we know they're here in high numbers because they dump around as i pick up of plans . and what they damage looked like is they caused their leaves to become brown. the leaves also, i'm recall on themselves. and so the plants in the sites is heavily damaged. and that's basically what we would like for the rest of how to be as put them in the evening light. the success of the operation can be seen particularly well. swarms of plant hoppers fly over the water hyacinths. nevertheless, the plant will probably never really disappear. it spreads too quickly. even so large open water areas have re emerged on the heart of baseboard dam since their introduction. this promising result could lead to the plant opera is being used on other infested waters. rethinking agriculture and how to use in nature or plants in a different way is something that affects everyone around the planet. i hope you

enjoyed or in depth look at the topic. sadly, it is time to say good by already. i am sandra. we know you're in uganda tuning next time next week. thanks, sandra. it's also time to say farewell from nigeria. if you want to know more join us on our social media or right to us. i am chris ellipse ticket. ah, ah ah, ah, with
