startup entrepreneur had a specific goal to build the best optical instruments in the world. little did he know that devices bearing his name would one day feature in the moon, minding through science, into new realms. the rise of a global company, $175.00 size distorts. june 19th on t. w. o . a one. welcome to the latest he should have equal africa. the weekly environment show focusing on stories from europe and africa. i am sandra tree novia,

here in uganda and a jane me is my coast crease. yes. hello from nigeria? i am chris alarms. wonderful to have you with us and hopefully we're good to inspire you. yes. what we have coming up over the next half hour. electric rich shaws a healthy, the environment is dam filters, all st. drain strapped micro plastics to stop them and finish yours. and we'll look at the green fight to save the world's coral ribs. where start of the show with the sun, which is the plentiful so fly in africa. but not everyone takes advantage of it. only a limited number of private homes in south africa. for instance, a solar panel on the roof most are still dependent on the cold part, electricity, greed, others have no electricity at all. just think of all the former settlements. but there is hope o german start up is teaching young people about solar power. in addition to bring

in green energy to homes, it also generate jobs for younger generation. with south africa is addicted to dirty energy. it produces more than 80 percent of its power from coal, making it the 9th largest c o 2 producer in the world and creating a lot of problems. droughts are becoming more common in 2018 cape town with its millions of residents almost ran out of water. that's why south africa has set an ambitious goal of shifting a quarter of its energy production to renewable sources by 2025. that includes solar energy, but how realistic is that private investors are building giant solar parks. currently, their production capacity is $2.00 gigawatts,

around 5 percent of the countries. total power production says of africa has um, a really successful program to invest in, in utility scale solar. so massive solar farms we've been on, we've been really successful in building a program. people do that and we've got a pretty close to 60 of those forms up and running this but the country is still having trouble providing its citizens with reliable power. the state power company as com, is nearly bankrupt. frequent blackouts are almost a daily occurrence. and here at freedom farm, an unincorporated settlement near cape, down, there is no power at all. none of these homes are connected to the power grid. that's where the social enterprise i. solar comes in. their solar power units provide power to individual homes and are a small part of south africa's green transition. we st.

mrs. is the al class check on the panel, take care of it. and then you will add la along a to it's, you went the way to the dollar solar system. that was, is made you a house called for a customer. these for around 3 euros a month. you on a practice can lighten her home doc loop and not many could athletic bentley again know, can look at that unit. i can think i can do it cuz i can, you can, i'm not using candles anymore for sure. me can. i cannot switch the lights on, instead of my kids can watch a bit of tv check light tv and charging cell phones. that's the system's upper limit, but it's better than nothing and it is sustainable. i. solar has already provided affordable solar energy for around 2000 people, including you want to practice. for most households that draw power from state

sources, the investment in solar power isn't very attractive. a high capacity solar system is too expensive for many and feeding the excess power back into the state grid isn't worth it. it's just make it easier for people to register their systems. i'm and getting on the system and legally compliance. so i'm scape down is probably one of the salary that's gone for this in that regard. many other municipalities don't have any kind of system in place or you won't get paid anything for power. you feed back into the grid. but many large companies like the shopping center are opting for solar power systems, less out of concern for the climate, but more out of fear of blackouts and raising energy costs. and that's causing a spike in demand for solar panels. green solar academy teachers courses on solar panel installation useful knowledge for those and looking to qualify as solar

technicians. there also people coming here, they have no expense whatsoever. they come from a complete different industry, but they see the chance for themselves to develop an opportunity here for themselves. france, lisa is an electrician who wants to specialize. taking part in the 5 day course, cost him around $700.00 euros. i want to open my own company and be my own both. so that is the reason i'm here to follow the way to go. the economics of energy has changed a lot. so energy generation is being the centralized renew was spreading every way . it's not just any more that you have a, a cluster of coal fired power stations, inspiring the country. it's now sprayed everywhere in south africa, solar energy and other renewable energy sources like wind make up around 12 percent

of the energy mix. another 4 percent comes from nuclear power, but the country to reach its goal, it will have to double those numbers by 2025. staying with solar pause. sudan is one of the largest economies in africa, was been ravaged by conflict of recent years. the standard of living remains low for many and now to warn ukraine as also lead to higher oil and gasoline prices. so how about solar powered vehicles? we make an innovator who's electrically part 2 tubes already saving money and benefiting the environments rush hour into dan's capital. cartoon. many people traveling to work or back home, go on foot or take the bus. few can afford a car of their own. that's why motorized rick shows or took talks are often used in the city which has over 6000000 inhabitants. but rising gasoline prices mean that

driving them, increasing me doesn't pay. sudan also has severe fuel shortages. drivers have to stand in line for hours just to philip in mohammed sammy as work shop mechanics are working on an alternative. electric rick shows some even have a solar panels on the roof after all, electricity and sudan has also become more expensive. and there are often power outages, we felt we'd go out over the electricity problems will affect our vehicles. to get me any more, when power is unavailable, hadley, our drivers will be unable to charge them for a listener. i'm a little more back, so we installed a solar panel system and i talked talk so well, what a lawyer that enables the vehicles to increase their range by up to 50 percent for lead to something depending on their cargo. they can travel 80 to a 120 kilometers. last year, mohammed sammy as sold over a 100 electric,

took talks within her geek the leather that we considered sir dan sustainable development goals. in our model. we've been able to create jobs and we manufacture a means of mobility that uses renewable energy and produces fewer emissions. i said, he's convinced that transporting cartoon will go completely electric, at some point, making the city quieter and its air cleaner. cool, fancier ride in one of those. next we head off to europe for not a less visible traffic related issue. cause aunt bosses are of course, major polluted. but notice on account of emissions. michael plastics. it's generated by taiyah and we're from old, sonic, and up, you know, see, was a phenomenon that someone reflected once the bread zone and beasley doing gibbons

bah, more and more cars means more and more tire where the resulting particles contain now just rubber and steel. let micro plastics to through storm drains these tire particles, get into the sewers and flow into the sea to stop them entering the water at all. researchers at berlin's technical university developed a special filter with support from the audi environment foundation. the urban filter is installed in storm drains and converts you wired to listen to this. our goal was to address micro plastic shop, mainly from tire abrasion. but of course, the waste water from our streets contains much more litter in all the plastic packaging the gets thrown away vacaville from van. so the scientists also put larger particles through the filter. recently, after 18 months of testing,

they installed the 1st filter on a busy berlin street and discovered to their surprise, that most of the fine particles littering our roads are magnetic, with andrea guns into some coil. interestingly, we found out that magnets actually do interact with these, especially fine particles into again. so now we're in the process of integrating such magnets need no armor hominid magnetism enter these shafts and are filter concept concept in degree m. intelligent networking with the st cleaners is also planned. is heavy rains are forecast, streets should be swept beforehand to keep drank and micro plastics out of the water altogether. and how about you? if you are also doing your best, tell us about it, visit our website, or send us a tweet. past tag,

doing your bid. we share your stories back to africa now of fishing communities here and around the world are starting to feel the impact of extreme weather and the coastal erosion. hundreds of residents of the total islands off the coast of sierra leone of honda, to resettle on the mainland, the government, hans dick and oxen. but will that innovation be enough? with a couple of years ago, it was possible for the people of young guy i'm and to walk along this stretch without getting wet. but the rising sea level has split one of sierra leone. st turtle islands, in to more than half of the island, has disappeared. the archipelago was once a bustling fishing community. now 500 people have been forced to leave in the past few years because their homes were washed away by floods. warm

one of them is suleiman cover. he is already built 2 houses on the island. now even the 2nd one is threatened by rising water. most of his belongings, he says, have already been carried out to sea vivia grapple. this is where i grew up, and i have lived all my life here. what told me it's where i built my house. and miss 1st the water washed away the last trees. so and then off my i took my house with it, hold us, i will. i will said to. i built another house more, but the water will soon take that one too. oh, missing. now i have left the island and settled on a larger one, so that is nearer to the mainland silliman cab. i can't afford to re settle the whole family on the mainland immediately. his wife still lives on the young guy,

and his children are with relatives. starting a new life is expensive. most people here live on no more than $0.10 a day. slim uncover now tries to save some of the money he makes from fishing. so one day the rest of his family can join him. now he lives on shore bro. island, but even there he is afraid of flooding. the threats of rising sea levels is very real. a few years ago, waves broke through the flood war in order to restore the damage seashore the municipality, and the government found international partners to finance this large scale project . and this time they want to do it better, says the mayor, we are worried that her, if we are a pro active to take such him to she shows, you know, to restoring the c face wall onto also and showing that we maintain

a while green mound. roof over, it could be disastrous for our people, our shuttle island. this new embankments will be almost 2 kilometers long and one meter taller than the highest tide measure it so far. now the authorities have started to involve the local population in measures to protect the climate. mangroves are being planted fishermen alford are low, looks in on the young mangrove plants nearly every day. he says the roots will bind the soil and protect it from being washed away in the rainy season. for suit to my, these mangrove roots will help the ground become stable again tomorrow. but if we don't plant here, then the problems will remain. houses will be lost and people will have to my great again. the mangroves and the embankment project give him hope, says alpha jello. but he knows that a lot more will need to be done to protect the homes and livelihoods of the

thousands of people who still live on show bro, and the smaller turtle islands. and while a sea levels are rising, our oceans a home to a precious aunt, endangered shelter for the marine life coral reefs are one of the most by a day vast ecosystems on the planet. but climate change onto destructive human activity might soon see them disappear completely, researchers and are trying out some very unconventional pushes to make the highly sensitive reefs more resilient. coral reefs are unlike anywhere else on earth. they're home to mind blowing. biodiversity, the world's reefs are shown here with red dots. they cover less than one percent of the ocean floor, but they actually support over a quarter of all marine life considering these staggering statistics. it's easy to forget that they're actually built from tiny animals. coral polyps, corals

a great deal of their magic and their beautiful color to a complex cooperation between organisms. algae live in the polyps, tissues and provide nutrients to the coral in exchange for protection. but this delicate teamwork is under threat from climate change. c, o 2 emissions dissolve in the seas, making a waters more acidic and weakening coral skeletons. and that's not all. as global temperatures, sore, coral reefs suffer through ever more frequent and intense ocean heat waves. extreme temperatures caused the algae to produce harmful chemicals, prompting the coral polyps to kick them out. this is coral bleaching where vibrant polyps turn white from heat stress, a process that can eventually prove fatal. and global warming is already driving vast bleaching events today. so we have to have multiple strategies in addition to

marine protected areas. this is lizzy mccloud whose global coral reefs lead at the nature conservancy. researchers like lizzie mccloud, are going one step further in the quest to help leaves resist climate change by investigating how to actually toughen coral reefs up with. and so some of the strategies people are using is, are taking corals that are we call express hardened. so they're better able to deal with ocean warming and actually transplanting and moving them from those areas to other areas. with holsted, they'll pass along that trait to their offspring and help the corals in that new area be better able to cope with warming. one way of doing this is to find naturally, heat resistant corals that have survived hot waters before into transplant them from one reef to another. and these aren't the only cutting edge techniques other teams are also hoping to toughen up the individual corals

themselves. in my research, we are mostly focusing on increasing the, the tolerance of corals to heat. this is ecological geneticist, madeline van up. and she's investigating a range of approaches to make corals more resistant to rising temperatures. for example, selectively breeding. to toughen up the pol of animals, or alternatively, tinkering with the algae that give coral their colors. the micro, i'll get a lift inside the carl tissue. we can take him out of the coral and most of these can be cultured in the lab. and in the lab, we can increase the rate by which these l gate evolve. madeline run up and used this approach to create heat resistant algae, which when put back into polyps, created more heat resistant corals. if we implemented every tool in our tool box today from marine protected areas, reducing pollution using some of these more active interventions,

stress hardening or manipulating the genetics of quarrels. it will not be enough to save cor, reeves, if we do not reduce emissions that is absolutely central. the truth is that coral reefs are incredibly sensitive to warming waters in 2018. the inter governmental panel on climate change warned that even if the world limits global warming to $1.00 degrees, coral reefs could decline by 90 percent. if temperatures increased by 2 degrees, that figure is 99 percent or higher. our environmental decisions around the world, whether that's reducing plastic use or limiting global warming, could make all the difference for the future of the world's reefs. we know a sophist when next land best report. zimbabwe loses around $300000.00 haters of forest every year. one reason would is bond to kiwa tobacco,

a key cost group in the country, but that also contributes to greenhouse emissions. what are sustainable alternatives? industrial, hemp might be one, but efforts to process the plant are still at an early stage. we decided to take a closer look at the concept of growing hamp on a large scale. it takes a lot of wood to heat this drying tower. each year, farmer tuck murray, missouri horner burns, 60 truckloads full to cure some 4 tons of tobacco. as well of more than 100000 small tobacco farmers in zimbabwe, he earns a good living from his crop danny, my quote on when i sit in is i've been growing tobacco for close to 7 years now and is shandra lew and it's transformed my life completely oh, casa no ting. i ran a moonbeam. i've managed to buy my own cattle, my own,

and my own car. my tongue was you going to listen a little one result of growing tobacco. it is that sourcing firewood is now a challenge to needs are old and it's a routine to remove voice tobacco farming earns and bob weigh more than $780000000.00 us dollars in revenue in 2020 but as far as have paid a heavy price, it's estimated that zimbabwe loses $60000.00 hector's of woodland each year to tobacco production alone. these plants a meant to put a stop to the deforestation, industrial, hemp, zera's i. m or a vicki, give up a job of the dentist to convince the countries farmers to cultivate hemp. then she, she believes it can save, not only the forest, but the climate to an acre hecta of trees absorbs 4 times less of carbon dioxide compared to industrial hemp. and we know that industrial, hemp grows much faster than trees. that means our him forests can do much more

in a shorter space of time in helping us absorb swear, remediate, and, and look away. cabin hamp is also very hardy. it's less sensitive to rising temperatures and it's easier to care for than tobacco. but in contrast to tobacco, you can't smoke. this hem hem farming is still in its infancy in zimbabwe. there just $100.00 hector's of hamp plantations in the whole country ticket t gun easy is. i have pioneer his 2000 ham plants i intended for the cosmetics industry. he grows them in his own greenhouses, and his harvest goes to customers in asia and europe. he's hoping to earn a healthy profit, as every part of the hem plant is valuable. the hem you use from this seed, from their leaves, from this talk in the root also, so you don't throw in anything out of it. the tobacco, they used so many chemicals in the also the usa, the pro and the cost of producing tobacco. ah, were, is actually higher than the cost of producing

a him. so it's going to if i take tobacco in the next 5 to 10 years, if we promote it, will he call be right in 2019 the global market for industrial hampers. what some $5000000000.00 us dollars and demand is growing. camp fibers, i use the construction and auto industries and for fashion accessories, hemp seed for food and drink. so the prospects are good for farmers looking to make the switch. but in zimbabwe, they still need to buy a license to grow hemp and many can't afford that. so as i am or a week, he has brought together a few farmers to try to convince them of the benefits of cultivating hemp you. my pity took a more im was a herana is here to you, my pity you can let grammy the to me to, to the so to death on a something so because of the changing weather patterns from wiser woody mile finally for you. i now wish to compliment my tobacco foreman with other brazilian

crops she knew in their own remark, mcclain me to lose so much either with or with the day with them and that our government can come in and support us farmers and growing crops like hemp to the may holiday, that's when it will become a success new sunday, sitting by g with the in all over. there are my paper there as i am or a vicki has come to this trade fair and below i owe money kits and bubbly 2nd largest city. many international exhibitors are here and she's hoping to find new clients as well as farmers will try their hand at growing him. the 1st ecs one has given me 3 tons of him flower into switzerland where we are seeing the numbers in pieces i. they may be dated to until we almost getting to 20 tons with them and they're old, destined for export because them probably has no professional hemp processing industry. just a few enthusiast cunningham fibers into handmade paper and that's not enough. if hemp is saved, the country's forest, ah,

and don't run so another shoe pocked with information innovation and ideas. hope you had a lot of takeaways. thank you for watching and good bye from uganda. thanks also from me. stay tuned and don't forget to visit us on our social media channels shown on your screen. have a lovely week at bye. from lagos, nigeria. ah ah, ah, ah, with
