there is a lot that can be done to. make up your mind. have a little everyone good to see you it's a beautiful day here in lagos not sunny but just the way we like it now did you know that too much of its official life can have a negative effect on our health on the world around us i'm so you didn't think of

that we'll have more on that later on on the show welcome to the environment show eco africa a military way then to visit kano park in lagos now let's see what's coming up on the show today. we'll take a look at a cleverly designed and which stands free street sweeping device in gonna. find out why farmers in the netherlands are big fans of bad see. and hear about how people in the ivory coast are protecting baby turtle. and now we're off to kenya the east african country has a high domestic energy demand i mean many sectors including the team the street people came to find alternatives to fossil fuels kenya is africa's leading producer in cary coal country there are several t. processing companies that are using sustainable energy sources from the local area let's go have some tea.

when the sun shines the rolling landscape of times he comes to mind the fields are covered in t. . the special climate here makes its pinions most important green region. really has a plantation here is one of hundreds of thousands of small will the farmers who make a living. he is the base just north of income the main source of income i have the bullies completed from and i've been to. play nice with him but he's on the. eastern. sported to that of his son in the front tree here walk us divide up the leaves into batches and prepare them for the drank process. the factory uses

a great deal of firewood but because of deforestation wood is becoming less cuss resource in the region. so the factory has begun replacing it with a brick it's made out of sugarcane residue you. about the progress compacted more to grow a lot of storage space and it's also very easy to transport them no less bulky and from units you know we talk about we were able to you know more and i do them by word. liberal get some meat in a nearby fast tree the end made of sugar cane fibers a west product that is left over in sugarcane production sugar factories often dock there is a deal at the roadside where it trough and emits the greenhouse gases come on the yolk site and me thin. but in this processing plant it is turned into a funny resource fast the sugar can residue is dried and shredded. then

it's pressed into briquettes system made out of a west product no additional land has to be put under cultivation. brasier diaz chavez is an expert for sustainable energy and has been assessing the environmental benefits of briquettes. b.c. same language circular economy so this is what we want to promote with bio energy and bio khana me how you can really have around that cycle for biomass back to the tea factory it has been able to replace one 5th of its firewood with briquettes. and at the t. factories are following suit training their workers on how to make this week the hope is that one day they will be able to phase out firewood completely.

if they succeed it will help preserve the remaining woodlands and protects the habitat of numerous animals and plants it would also benefit to the tea plantations and homicide. he said when they use the brigades the company. uses the expensive and this is money and the money saved goes to the promise for the environment and the team produces in kenya to bring a sustainable solution with potential the potential to make even. in germany like in many other places forest fires are a growing problem so understanding how best to help for us recover i regenerate is more important than ever a group of scientists decided to see what would happen if a force destroyed by fire well left more or less change own devices for several years we may think we advance in many ways but as is so often the case when given

the chance mother nature will heal herself even from damage caused by humans like us. with beech trees maples or estens jeanette's blue murder and here are always glad to see a new member of the family arrive about 12 months ago the 2 researches began documenting changes big and small to this section of a forest ravaged by fire. we got what we hoped for i mean the ecosystem is starting to recover and certain species are quickly appearing and spreading such as these aspens they've now brought about changes to the area that are in turn helpful for other species. don't for a good 6 and in aug 28th seen a forest fire raised almost 4 square kilometers of woodland outside the town of

twine pleats in eastern germany an area larger than 500 soccer pitches the usual practice after a forest fire is to clear the entire area and replant trees as seen on this private land but not in this case thanks to a government funded project here dead trees are left standing. in local forest think it is testing an alternative solution removing most of the dead pine trees and planting other species in the place the idea is to create a mixed forest that's also home to oaks poplars and other deciduous trees. to me so i can i 1st wanted to see which species of tree i could use and how old they need to be before being transplanted carrying out tests is important to get the full picture 1st. and that's when the forest abroad in the expertise of these

researchers they're here to find out the best way for a forest to be able to regenerate and become more climate resistant with or without human assistance. the researchers take a hands off approach limiting their work to observing which plants and animals settle in the habitat it's a rare opportunity. it's now standard procedure to see to it that we repair the damage that humans have done all too frequently we do not give nature the time or space to do that itself and that deprives us of the chance to learn from nature to forgive him for all the false stuff and. among the things they have learned is that in addition to providing shade dead wood also in the hands of the soil when it falls to the ground it creates more humans which gives the soil more

moisture the work is carried out on his test areas is on a smaller scale and is common in conventional forest management they're really accessible by car and he's a wreck to defense around the forest to keep the larger animals at bay he left a number of dead trees standing leaves have also been spread to keep the soil moist and protected during drought. we're seeing large scale forest fires in the region and that's going to continue so we need to learn how to respond to. that and that's why researchers in that blue murder is here she's been collecting data on soil humidity and temperature which plants and animals settle there and how all these factors impact on the ecosystem 8 other research institutes are also involved in the project the data gathered over the project's 5 year time frame is being collected at her university and it was filed in nearby lynn but he doesn't have it strike death data shows that natural reach even nation far exceeds the number of

trees planted by humans. we have seen up to 3 times the amount. naturally resettling can head to the rhine or oak trees that were planted on the area. after i think a found wooden. the researches are also part of an international network there we get to hear about the experiences of colleagues in the us and mediterranean countries and to learn if and how forest ecosystems can be made more robust. starts and if you wish to go on zotz cooling our work is really important it can help us to compare biomes or large ecological zones so that we can discuss common patterns or and also told. one thing a number of studies show is that even the remains of trees killed or damaged in

severe fires help the forest ecosystem rebound which supports the argument of letting nature be. now we've got equal africa love people will take initiatives to help protect the environment our next report looks at a young innovator who has a truck with of a finding cost effective solutions and sustainable wants to do the problems facing his community his latest suit will bring jobs a bicycle that doubles as a little sweep up here is this week's doing. this is no ordinary thought i can trade. this sweeping bicycle collects trash as it travels the streets of a crowd on its inventor frank darko is on a mission he wants to help clean afghan us capital. but i'm not happy when i go outside of our day and i see so many reviews from the ground is so sad and i want

to see someone east from another country go can i run i feel like fighting but i want to topple the regime so really is my new invention i am i believe i come if i can build a country all i can put an end computer something to do that to restrain a response from the streets. people it is sweeping bicycles together from discarded bikes and scrap may so. it takes the south to engineer around a month to complete one. it's just one of several inventions he's working on. frank talk and hopes he will one day own a factory and his eco bike idea will sweep across the nation. and how about you if you're also doing your bit jealous about it visit our website or send us a tweet. pastor doing your bit. sharing

your story. pollution is a problem all over the world and comes in a range of forms some obvious like plastic waste in our rivers and oceans all of a cloud of smoke billowing out of factories but even some things we consider useful can be the souls of pollution and have their own kind of impacts on our wellbeing we shed a little light on the issue in a new segment called eco day. gazing at a sky resplendent with stars. something many people around the world are sadly no longer able to enjoy. and advance thanks to artificial light while there are no up to date figures available in 24 team the skies over hong kong were already 82 times brighter than they might be naturally. we suffer

sleep deprivation from too much artificial light including that emitted by smartphones. it also disrupts the orientation of nocturnal birds and insects. our energy consumption could also be cut drastically by ensuring responsible outdoor lighting. for starters it would help if advertising signs and building facades were to limit aided all my long. and if nighttime lights were used only for the places where it's really needed. some cities have already committed to minimizing artificial light such as fulda in germany it's among the $29.00 places so far to earn recognition as international dark sky communities. cities like these make it possible to see the

starlit sky again and reset the. body clocks of us creatures to their natural rhythm. doctors not only helps us get a better night's sleep it's crucial for maintaining a balance in nature light pollution poses a serious threat. to scenes like bots however scientists in the netherlands found a solution to this by creating special refuge areas for the flying mammals and that isn't to keeping the bats safe they also make sure the. system is preserved. and there's one. and their special one a figure at least. far away from the bright lights of amsterdam dr commute is after creature that likes to operate under the cover of darkness.

he is studying how lights are affecting bats so far his team has found that the 19 species of bat found in the netherlands react in widely different ways. and that's have a very strong response to those actually driven by mostly by fear of predators so if you're about that flies very slowly you better hide away and don't show yourself in the light because it's it's risky however if you're a bat that flies very fast it's very agile it don't need to be afraid that much for predators so you actually like taking away. from the slow flying species and giving it to these already common. but species that's what course not a good thing in terms of biodiversity you actually reducing biodiversity. not total

species are sensitive to the blue range of light as they have evolved to use the moon to navigate and brag to the blue the more distracting it is to test how species respond to other parts of the spectrum the researchers have put up almost $200.00 posts around the country that shine a range of colors. if you take away the blue part of the spectrum and and compensate by a bit more rant which you actually see here 'd. it may actually be less intrusive for these not the most reaches not all species may not perceive this light as intense and that's exactly what we have observed. the world over brightness and luminosity are growing at a rate of 2 percent per year. as the night gets more illuminated studies are linking light pollution to destructive natural cycles as well as mental health

in humans. and they are outside eindhoven farmers on a cold and carlos phase are also members of the community fighting for darkness and its bouts for reasons of their own we try to. kill well you would say the harmful insects in a natural way so we use. insects to cool to kill other insects and that's where also the bats common because birds eats lotsof 3 1st verse they actually eat the roots off to fruit trees especially the apple trees and so if the bets in a lot of schaefer's we don't have those terrible groups in the ground eating on the roots of the trees so. that's why we like best. that work is

natural pesticides and iron essential part of how the ecosystem of the arch and functions of. this farm even has a back hotel to make the mammals feel extra welcome. you can see over here. that the that there are better living in the better trial because the civil courts over on the move. there excrements their prove the community around has installed special bat friendly lights in the area to make sure the animal stay put as night falls. but if you don't eat. around 10 pm the bats check out of the herd and disposed through the farm ready for a meal and to play their role in the ecosystem. while. maurice donner's is a researcher and signifies at the company in the design the lights around the

orchard. no. he explains that lighting is more than merely installing glowing lamps. we need lighting but we do solution do it in a really sustainable way. so obviously energy efficiency. in. great to cradle solutions but also in the direct effect is fighting enough and you have to optimal effect on their own the whole ecosystem and not just on people. but some districts in the netherlands have in fact become darker as a result of such initiatives a satellite images show giving some of its residents and its resident bats the beloved's night sky back. like these beautiful birds returning to africa we head to a beach in the southwest could the watson meet another group of people who invest

a lot of time and energy to help keep animals safe is birds are having fun here in this case sea turtles these mayan reptiles spend most of your lives in water but often those lives depend on them surviving a treacherous call to this earth after hatching on the the sand just as well they've got help us to help them make it safely and that epic little journey. dog mrs fallen in granbury of the a coastal village in cape of wa every night these men are out skier in the beach looking for sea turtles their wildlife conservation ists. by morning bass picked up around 30 baby turtles found in a nest. the tiny creatures would release here near these rocks. west on their way up like

a bad man to have been an unlucky part of the beach with very many rocks or places to take over so we look at them to the rocky sports where they can hike from 3 d. to the dock there to see. the lucky. star throwers had many not to unloose both online and and it was him that i knew that i thought enough of the ganga there to see there are sharks and fish and on the beach craps all bets and snakes all prey on temple if they want and then the filthy female sea turtles return to lance and lay the eggs in the sand after a 2 month incubate in the freshly emerged hatch then scott on the cross the beach towards the sea name more than 5 percent will reach maturity the figure used to be even smaller of all the prejudices humans about fog the worst until just a few years ago sea turtles in the eggs were hunted and eaten in granbury the i always think you are them i was

a poacher i would say lots of them 5 or 6. we hunt them at night with my churches and torchlight washes often with the help of dogs the lawyer does this when i see a total issues like my baby brother or sister or my mother if you like family to me . the n.g.'s c.n.n. has been active in granbury be synced. 2010 i sensitizing locals is one of its main challenges i maritime police play a big part in the project based supervise the region's waters and clamp down on anyone in the gally hunts and sea turtles. was just what i next in globe a vegan and inspect fishing vessels returning to land. in a bid to depeche the depeche or there are 2 types of fishermen these again the

answer fishing nets so sometimes when they're fishing the catch totals but they don't do it on purpose seeing a lot in a lot. as well but they're also liberians who use fishing lines to cross the lines they can cook totals demur in please don't catch them at the show and sell the tuttles sit in a property buy and on the 11th. 6 maritime police patrol here in addition to monitoring illegal fishing they also raise awareness and distribute special nets provided by the c.m. that enable turtles to escape capture. i these divers of course the sea turtles but their intentions are strictly scientific they're marine biologists and will return the reptile to the sea in a few alice sea turtles are a threatened species the research is attach a g.p.s.

so they'll be able to keep tabs on the turtles feedin and migration habits. i. also highly know almost nothing about their lives in the scene as well as where they spend 99 percent of the time what it is difficult to research the hundreds get. the data collected will help in planning and. same in a conservation same for the species ultimately did was environment ministry in cooperation with the engineers is working to turn the country's largest c to 2 nests in an area into a vast moving reason. it's amazing to think that those cute but helpless little creatures will grow to weigh as much as 700 kilo are you active in animal conservation yourself write and tell us about it you can find us on instagram twitter and facebook that's all for this edition of eco africa i hope you
