beethoven is for us. beethoven is for. beethoven 2020 the 250th anniversary year on dio you. had to know 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 sure 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 identity kind of 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 ambitions 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 t.v. industry people came to find alternatives to fossil fuels. is africa's leading producer in cary coal country there are several tea processing companies that are using sustainable energy sources from the local area as to how some see. when the sun shines the rolling landscape of times it comes to light the fields are

covered in t.-bone. the special climate here makes its king his most important grain region. he say archy big ruling has a plantation here he's one of hundreds of thousands of small will the farmers who make a living going to. the east pastis north of income the main source of income i have the buoys completed and i've been to. 4 points of support he certainly. should not have been. oughtn't to that have a sunny day factory here walk us divide up the leaves into batches and prepare them for the drying process. the truck tree uses a great deal of firewood but because of deforestation wood is becoming us cause for source in the region. so the fact she has begun replacing it with

a brick it's made out of sugarcane residue you. about the recruits compactor more to grow a lot of storage space under it's also very easy to transport them no less bulky and from units we talk appear to be able to you know more and i do them by a. liberal get some made in a nearby factory the end made of sugar cane fibers a west product that is left over in sugar can production sugar factories often dump the residue at the roadside where explored and emits the greenhouse gases come on the yolk side and me thin. but in this processing plant it is turned into a file you pull resource fast the sugar can receive is dried and shredded. then it's pressed into greek it's system made out of a west product no additional land has to be put under cultivation.

diaz chavez is an expert for sustainable energy and has been assessing the environmental benefits of briquettes. this is in 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 other t. factories are following suit training their workers on how to make the switch 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 the tea plantations

and families like in saqib it. is that when they use the brigades the company also uses the expenditure and this is money and the money saved goes to the farmers. for the environment. like in many other places forest. so understanding how best to help forest recover. this side of it to see what would happen. to several yes we may think we are many ways but so often the case when given the chance mother nature of. humans like us. with the beech trees maples or aspen's.

and. 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 the forest ravaged by fire. we got what we hoped for 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 help for other species. goods he said in august 28th seen a forest fire raised almost 4 square kilometers of woodland outside the town of 20 it's an indecent in germany an area larger than $500.00 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 standing. local forests to do. i think it is testing an alternative solution removing most of the dead pine trees and planting other species in their place the idea is to create a mixed forest that's also home to oaks poplars and other deciduous trees. for me so i can i 1st wanted to see which species of tree i could use and how old they needed to be before being transplanted carrying out tests is important to get the full picture. 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. to give it's now standard procedure i just 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 salon. 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 humus which gives the soil more moisture the work has carried out on his test areas is on a smaller scale and is common in conventional forest management they're barely accessible by car and he's a wreck did

a fence around the forest to keep 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've seen large scale force. fires in the region and that's going to continue so we need to learn how to respond. and that's why researchers in it 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 collated at her university and it was filed in near bilin but it happened habits like death data shows that natural reach even nation far exceeds the number of trees planted by humans. we've seen up to 3 times the amount of

naturally resettling compared to the fine trees that were planted on the area. i think of wooden. the researchers are also part of an international network they're eager to hear about the experiences of colleagues in the u.s. and mediterranean countries and to learn if and how forest ecosystems can be made more robust. to go on is arts 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 the 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 are equal africa love people who take initiatives to help protect the environment our next report looks at a young innovator who has a truck with a view of 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 here's this week's doing. this is no ordinary if i can trade on. this weeping bicycle collects trash as it travels the streets of a crime its inventor frank darko is on a mission he wants to help clean afghan us capital. and i'm not happy when i go outside. and i see so many robberies from the ground up to suicide and i want to see someone is from another country go cannot run i feel like fighting but i want to be tough in the regime so believes my new venture i am i believe has come if i

can build a country all i can put an end to do something to do that to restrain a response from the streets. he puts his 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. from dhaka 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 tell us about it visit our website or send this or tweet. after doing your bit. sharing your stories. 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. gazing at the sky resplendent with stars. something many people around the world are sadly no longer able to enjoy. and events thanks to artificial light while there are no up to date figures available in 2014 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. christan hers it would help if advertising signs and building facades weren't eliminated all night 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 fold 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 seem to have found a solution to this by creating special refugee who is flying mammals and that isn't to keeping the bats safe they also make sure the. system is preserved. and there's one. and then especially on a figure against. far away from the bright lights of amsterdam ducted commute is after creature that likes to operate under the cover of darkness . he is studying how lights are affecting bath

so far his team has found that the 19 species of bat found in the netherlands react in widely different ways. let's have a very strong response to light there's 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 risky however if you're a bat that flies very fast and is very low you don't need to be afraid that much for predators so you actually taking away. from the slow flying species an extinct giving it to do this already common. but species and that's one of course not a good thing in terms of biodiversity you actually reducing biodiversity. nocturnal species are sensitive to the blue range of light as they have evolved to use the moon to navigate the brighter 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 lamp posts around the country that shine a range of colors. if you take away to the new part of the spectrum and and compensate by a bit more rant which you actually see here. it may actually be less intrusive for these not the most species not all species may not perceive this light as interns 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 and often farmers are nickel and carlos phase are also members

of the community fighting for darkness and it's 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 eat lotsof 3 1st and the 1st 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 our roots to treat so. that's why we like bats. that's what is natural best decides and are an essential part of how the ecosystem of the arch and functions of. this farm even has a bad hotel to make the mammals feel extra welcome. you can see over here.

that is that there are vets living in the back total because the civil rights over here on the move. there excrements have proved the community around has installed special back friendly lights in the area to make sure the animal stay put as night falls. on the. around 10 pm the bats check out of the hotel and disposed through the farm ready for a meal and to play their role in the ecosystem. of all animal. mari's donner's is a researcher at signifies that the company in the design the lights around the orchard. you know. he explains that lighting is more than merely installing glowing lamps. we need lighting but we do solution do it in

a really or sustainable way. show obviously in energy efficiency. in. great to cradle solutions but also in the direct effect is fighting enough and we have to optimal effect on their own the whole ecosystem and not just on the people. but some districts in the netherlands have in fact become darker as a result of such initiatives as satellite images show giving some of its residents and its resident bats their beloveds night sky back. like these beautiful birds returning to africa we had to a beach in the southwest could the water 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 marine reptiles spend most of your lives in water but

often those lives depend on them surviving a treacherous call to the surf after hatching on the sad just as well they've got help us to help them make it safely and that epic little journey. doc misses fallen in granbury be a coastal village and take the every night these men are out scar in the beach looking for sea turtles their wildlife conservation is. by morning they fixed up around 30 baby turtles found in a nest. the tiny creatures would release he made these rocks. west on where. we have been unlucky part of the beach but there is many rocks or places to take over so we look at them to the rocky sports where they can write

from we detest the song. and the lucky. ones have many not to our movies but online and in. the pilot tell you that's not enough that the gathering at n.b.c. there are sharks and fish and on the beach craps all bets and snakes all prey on terrible winds and then the filthy female sea turtles return to lance and lay their eggs in the sand after 18 months in cubase and the freshly emerged hatch then scott on the cross the beach towards the sea name more than 5 percent to reach maturity the figure used to be even smaller of all their practices humans about far the worst. until just a few years ago sea turtles and the eggs were hunted and eaten in granbury i think you are i was a poacher i would sell lots of them 5 or 6. we hunt them at night with machetes and touch like that often with the help of dogs while you do things when i see you talk

to. my baby brother or sister or my mother if you like family to me i the n.g.'s see and has been active in granbury obese since 2010 i sensitized locals is one of its main challenges i maritime police play a big part in the project they supervise the region's waters and clamp down on anyone in the gally hunt and sea turtles. i have judged that i max and go have a regular and inspect fishing vessels returning some land. in a depression at the pressure there are 2 types of fishermen got these a guy nance with fishing nets so sometimes when they're fishing the catch turtles but they don't do it on purpose seeing

a lot. as well but there are also liberians who use fish in lang's just the lines they can cook. it demur in please don't catch them sharon saw the tuttles sea in a property by and on the eve of a. 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 enabled her to sue a state capture. i these divers of 40 sea turtles but their intentions are strictly scientific. demo. marine biologist 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 feeding and migration habits.

all said we know almost nothing about their lives in the sea of us that's where they spend 99 percent of good time what it is difficult to research the how to ski . the data collected will help in planning and maintaining a conservation say for the species ultimately codifies environment ministry and corporation with the n.g.o.s is working to turn the country's largest sita to invest in an area into a vast moving. it's amazing to think that those kids but the 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 enjoy the program to be sure to join us again next week and until that stay safe and be kind to others whether flora off out by.
