well yes. the industry is controlling your thoughts. great 20th century. president. raising the money to get. me through w. hello and welcome to another edition of africa i am sundered 3 no video coming to you from kampala here in uganda well it has we nearly 5 years since this show focusing on environmental issues foster went on air and we're looking forward to reporting on more and more amazing projects and great ideas for protecting and improving the
walled we all leave it as well as drawing attention to the problems that i gently need solving well here are some of the topics coming up on the program. because for me transportation to knowledge even made in africa an example going to kenya. popcorn and why it's not just for eating as scientists in germany will demonstrate . until next of course of a shift in south africa you sparing young people to protect white life. but post a with head to namibia more than 20 percent of the country is on the course of asian management it is home to incredible variety over a rare and in danger of species of animal including the critters the so-called cards need a very specific kind of environment to breed can't unmaintained be aborted temperature when it gets a very high. the trouble is that they often leave me
a rural communities and cause problems for people and their livestock now a way for farmers to drastically of course reduce their livestock losses without killing the beautiful big cards. a rest sighting of wild chicest in namibia. the country has the largest free range in population of cheetahs in the world but according to recent research still the numbers are little. here the population is threatened because it doesn't occur inside of national parks but on commercially used farmland there's obviously leads to conflict as the truth ok finally prey on livestock of the farmers. teeters population numbers across africa have dropped to less than $7000.00 worldwide as the habitat it's lost to farmland and house and cost structure portion and illegal
trading caps pause a federal challenge and because attack livestock they also get killed by farmers. scientists from germany is like nets institute have found a way to reduce that conflict to spent more than a decade studying chicest in namibia part of their study involves putting radio collars on the animals and monitor indian movements the team or not is that the cheetahs always return to certain areas of practice passed on from one generation to the next they visit these territories and mark read in the territory so we call this centers of the territories not a march the trees are you call the communication hops because territorial males they used these trees and also the oldest in the region around so these territories berries. stable you know always there and even if the territory hold us
does appear die then the new territory hold us up all day exactly the same place this allows the scientists to identify areas where she just complicate the den advice to farmers not to put a life stock in those places it's about 10 percent of the area that is highly dangerous because concentrations of to cheetos is very high and about 90 per cent that is much less risky for the harmers and that. the farm is that i've moved out of harm's way now that was far fewer on the most to the big cuts. this simple adjustment reduced the livestock losses by more than 80 percent and then solve the conflict for the farmers and for the truth as in many cases. reducing the conflict between humans
and money mouse means more survive and that has other benefits to these powerful pre-dates has helped keep the populations of grass and mass under control thus preserve in a montagne india calendrical balance of disadvantage. in what incredible creatures and what a great idea to promote a peaceful coexistence between the wild animals and the humans on this report is about a really interesting bit in south africa it aims to help communities live alongside animals in the wild as well as offer professional opportunities it is called the trucker academy and as the name suggests it trains disadvantaged the rural people in the traditional skills of way of life trucking. as it is sunny and. looking for this special friends in the. bushland of the level gamers of north
of johannesburg. a group of rhinos is hidden somewhere here. this is the front to pen. them spurs on the ground twisted twigs and droppings lead them to the animals. they're professional trackers. they were doing this tracking. for meat for their hunting they do it they did they through they started we were just carrying on when they offered but in a different way because then they would do we need for food we we have do we need for the for the well not to. not to kill but to protect. tracked his play a critical role in keeping the animals in the reserves safe. so that frick as
nearly 80 percent of the world's rhino population and has been hardest hit by poaching but since 2014 thanks to strict security measures reserves have hard drive killings from 1200 animals to about 600 in 29000. to keep his animals safe conservation manager had money does not only rely on devices. but they really do a lot of monitoring work especially on. conservation important species like. some of the big ones on we will utilize various forms of technology to try and track these animals and keep tabs on these animals but technology fell on you from time to time. and then we have to revert back to the basic tracking skills. this m r a reserve is part of the great career a semi desert region with characteristic wildlife vegetation soil and climate
conditions the reserve is also one of 3 training grounds for a very unusual tracker cademy today is examination day. has to show his instructors he can track an antelope in the semi arrid career by a. different one because even when richard is in front you. plant. a good track reach the environment and develops an intuitive feeling for the ways and habits of animals droppings are just one of many signs they read. just finally label hung by to find his target hidden in the bushes. grew up in the area that night in one long. hours see in the most annoyed this mall is the ones who and then you know what are the biggest in my leg or i know everything the inside and i was getting
that motivation of i want to go to the 2 to learn about those in the money and everything the academy is an injury that off is free training to $24.00 young rural people from various african countries each year realizing that only a few traditional trackers remained in southern africa onyx when you 1st started the school 10 years ago with the help of a private sponsor meanwhile the academy gets thousands of applications paid here. we are trying. because to do for the benefit of conservation and for the benefit of an ancient culture and to improve the lives of the students that come through our program the kids and yes and it is proving successful reign was 94 percent of all graduates are employed and the track is on need it many iconic animals like crocodiles leopards and cheetahs remain critically endangered. after a long day of working and learning in the felt the pupils returned to the boarding house will suffer for many of them heard of the tracker cademy through people from
their villages who went through the program and subsequently found work in the reserves they hope that they too will one day be a role model for their peers back home. the ones who'll be on the vonage boom in solar energy in 2018 accounted for 2 percent of one white in the christie use it and its share is growing fast experts say solar and wind are said to be the most sustainable sources of renewable energy in the southern hemisphere the international renewable energy agency sees that over the past decade it costs for solar have dropped by 80 percent let us now go visit an energy provider that he's building the biggest solar park in germany. these panels are pretty easy to install but there are thousands of them still to go
. in the countryside near berlin germany's biggest solar park is taking shape. half a 1000000 modules built on mount full frame. 100. posts . 250 kilometers of cable. 150 fishers working on behalf of one of germany's biggest energy companies. book we definitely have the potential to complete projects of this scale but rather than size it's the viability of the project that counts. this solar park is the size of 225 soccer pitches facilities in europe tend to be smaller because they compete with agriculture for the land but solar parks alone aren't enough here in germany there are 19000000 apartment buildings and houses
a lot of roof space. and an ideal place for solar panels. on entire industry has been built around installing. now adays the systems are very affordable and economical to run since you basically don't have any maintenance costs. have become so affordable to install that they quickly pay for themselves what is your what. mugshots owns a house with a rooftop solar system in many cases the system actually produces more energy than a household needs. does one of the things that makes it financially worthwhile is that the costs of heating your house or heating your water are pretty low.
the equipment paid for itself in just a few years. after that the electricity produced is essentially free. marks for us as energy needs do exceed what he produces though that is because his family have 2 electric cars that need to be recharged. off. solar energy is expected to see significant growth interim and. by the time the last coal fired power station is switched off and 2030 ac there would have to be 5 times as many rooftop solar systems on parks as there are now to cover energy needs . solar energy would then account for a quarter of the country's power i would push. back to germany because solar park
project 10 years ago the operating company was one of the biggest nuclear power producers in the country. still a bunch several coal fired plants but that will soon be a thing of the past. 39 interview in this new book these new energy sources will have to fill the gap they've become a central pillar in our portfolio. since 2012 we've seen growth in all new and renewable segments including wind both offshore and onshore as well as solar. you know these technologies will account for about half of our output by 2025 i mean. the solar panels just keep on coming day even on day as. talk so sustainable mobility tend to focus on the big cities in ways to reduce
traffic congestion and pollution and of course make life better on you give me basis on protecting you and what if you get off because well it's not so good do you need to you know a since it was developed you take. these handcuffs off in a way several 100 kilos and here in kenya's capital nairobi exultant noise are another problem for day laborers. kenneth plant ties invention could make life easier it's an electric powered car that goes faster and can carry more event in a system that. is because. to sylvia charge where do you wish to commit that. if you're looking to get more people who know that war is equal to gender so
even if you doesn't use doesn't bother you very well we'll see if you cook. dinner dishes to spare in the environment the new vehicle can get up to 7 kilometers an hour without using much manpower it's ability to power itself it is kinetic energy at its best and a big help for use this. month in the us there's only one by you our problem and everything is pathetic quite then. cream to achieve this squanto i developed electric rickshaw unlike noisy diesel took took this version rode through nairobi almost silently and without emissions it also carries fine of instead of 3 people you want to diversify to. utilize what they cannot and emitted can be made it can be in buses while we will be able now all of it up one of the midget electric more beautiful company you know africa
on top of that it's produced sustainably since all components of the electric vehicles come from the region. and taliban you know if you're also doing your bit tell us about it this is how websites oh send us the tweet. hash tag doing you hoping. we shackle your story. a little the things we use in our day to day life i made my point nothing on you was was you view was modelled on the back of the empire itself from the cars and from plastic prosecuting real since all flying high. and also just examples he's a terrible thing. scientists are looking for alternatives and sometimes come up with great ideas. there is a professor at mit doing. much of the things we call.
this building is getting added thermal insulation and damp roofing from polystyrene for every year over 10000000 tons of the synthetic material turned into everything from facade cladding to disposable bowls and cups and packaging. but one extremely useful the downside of the material is that it is essentially non-biodegradable and takes centuries to break down and as it does it releases miniscule particles into the ground water supplies. this man has a plan to replace the plastic pollutant since 2008. poor and his team have been looking into an environmentally friendly alternative popcorn. similar to polystyrene phone. consists of a mass of cavities filled with air. can see them when you dissect
a piece of popcorn and examine it under the microscope. that's what makes it so light. like the mark the researcher and his team have already used popcorn to create kitchen furniture they are showing many factories the range of potential applications for popcorn the 1st step is to turn it into a massive granules all the same size the original maize is grown in germany well that is land intensive on the plus side the material will help to reduce fossil fuel consumption. and you can read it and it tastes a lot like popcorn except there's no sugar or chocolate of course so the taste is a bit boring. thank the granules have been pressed together to form sheets or panels with plan proceeding providing the bonding agent as opposed to synthetic chemicals this makes the material compostable and even
suitable as animal fodder of the team are pioneers in the field. they also use a hot air gun to compare the thermal conductivity of polystyrene foam to that of popcorn and then measure the heat that penetrates through to the back in the case of polystyrene foam the sensor reads 28 degrees celsius while the popcorn board is even better at absorbing the heat here the reading is under $25.00 degrees. you can clip wood houses with the panels in the walls or on the facades also or you can also use them as insulation for solid wall building. demarc. tiriel also performs better in the flammability test the polystyrene burns up at a frightening speed immediately beginning to melt and release toxic gases.
subjected to the same flame the panel of popcorn barely catches fire. only reason the poor is happy to pass on the fruits of years of research on the material. or he hopes to see environmentally friendly products made from popcorn replacing polystyrene foam on a large scale and the sooner the better. the 1st popcorn packaging is due to go on the market in the fall of 2021 and will hopefully help to reduce the world's growing mountains of plastic waste. and new technologies can certainly make our lives easier but when the internal combustion engine was developed in the 19th century no one even the air pollution on serious
health issues it will be later that his white many you know they just call me to the finding it will be a waste of pouring machines on. when these innovations help to counteract play make change then wait to see for yourself. we that corn husks aren't uncommon in round out these days the current drought has lasted months and the increasingly extreme weather threatens the libel hood's of local farmers especially those in the eastern part of the country who are not quote could be attributed it's apparent that climate change is real and increasingly dangerous the farming seasons that people are used to are not longer predictable at times it trains where one expected drought well route instead of rain and it's confusing you can just farm and have hope over having harvest and what if you were an issue and when you aren't paying a couple. is one family who has been fortunate during these hard times have filled me a river so she's been able to pump sufficient water to her crops. but they do so needed
to power the pumps is expensive and the exhaust that is a need to as a result contributes to a greenhouse effect the researchers and technology experts from a random start up have developed a solar powered irrigation system. they had to project was financed by a u.s. aid organization and they run the government the new irrigation plant came at just the right time for 40 families from authorities in the district the drug made agricultural more difficult and the cost of renting the diesel pumps nearly consumed on east. to those fancy we ended up spending much of what planning on buying fuel while using the fuel pump into narrators ira with those little left for our livelihood now we have gotten great of all those expenses we only need to deplete someone to
water the plants. of the kurdish just. due to the more affordable it again. promise cannot attend a larger areas of land and keep farming they used a much higher a so resolved. but. i did call a hole i was only have a sting 50 kilograms of beans in 2 bags of saw them seize on now with so let irrigation the yield volume has multiplied by 3 when i am considering expanding my farming even on that one i'll be focused on the solar powered irrigation system should be out in bonding in all of party districts in the country by the end over 2020 this tucked up the bills the sun not even gets in system has also developed a system to michele the temperature and moisture of the soil since those calculate the exact amount of water needed by the plants. farmers i've been
notified by and up about when and how much they should water their crops the plants need to get the optimal or what they mean that's why we believe when they use this technology to improve their production. and it does been tested to be a success new the play which has robin doing. these pilot system is powered by solar energy a swim now the farmers know exactly which plants need water and how much of the need for the time being they improvising with plastic bottles which will soon be replaced by what to horses. it looks like technological advances will be key to all future that is all for today's show thank you all for being with us hope to see you again then i will be back with more exciting stories about the nature and of course of a should i understand a 3 no bill signing off in compiler care in uganda. do
