prints. the out with. fantasy. with. secret. starts december 25th. in the field of science has been helping humans understand the world and has need our lives easier from prehistoric inventions to want to learn communication technology watch me also use science to give back to me by studying renewable

sources of energy by building satellites that help us on the ground water levels by turning we use to improve new simple fields for me just a few want to be sure we introduce you to some people and projects who are using scientific inquiry to help the and why that alone welcome to equal india on something that i. for stock to be. invested in this region is one of the worst places in the country to be a farmer was distant droughts and green for many a farmer who give up farming and become an industrial. but if scientific data could accurately predict weather patterns and provide farmers with information they could still have a short and their primary like an organization in the region helping farmers best exactly.

a look at a smartphone past all he needs to know. now is the ideal time to fertilize his fields he also knows which fertilizer to use and in which quantity the 40 year old resident of shift village uses the farm precise app which especially developed for farmers in the indian state of maharashtra the app improves by making cultivation and livestock farming easier to organize. when speed and direction the sounds of the birds and when they make these sounds my final generation's used to use these as indicators to identify climate patterns will it end tomorrow we live in the day after will it rain at all this is how our elders used to predict the weather when a few years later we got the information via the radio then through the television

after that through newspapers our farming practices would be entirely based on that most of the time these estimates were incorrect. they were 20th on the. the mainstream weather forecasts kabul entire regions but local weather conditions can be complete. different. climate change is also making the weather increasingly unpredictable. dime and again droughts and floods lead to harvest failures in recent years. the watershed trust look for ways to help these. regions the result was precise and easy to operate up which functions even with only a weak signal. initially released. in strong argumentative weather stations in the program realizes so has to make

a community of it and we have trained locally who you would hope using baking observation from. shared with the community as their technology are the ones. we started getting online on an hourly basis. or put it to use to noted down the daily information about the. forecast and shared with the community. the fun precise op offers 5 day weather forecasts and up to date information for good field management all in simple language and easy to use. and resist i wonder whether we used to use any fertilizer or pesticide that we could get our hands on. but with the farm precise if i don't have enough information about a particular fertilizer or pesticide i can just take a photograph of the crop and post it on the chrissy some mud for them in the op.

within an hour we receive feedback and advice about what we should do about it or if we should use a particular substance in a particular proportion i do particular time of day. in 2014 farmers in the state of maharashtra to predation were hit by weather related losses totaling some 900000000 euros. since then the app hasn't only provided assistance for planting fertilization and harvesting crops. the farmers can also find the latest market prices and work out the best time to sell their produce as a result osgod mostly has reduced his losses and he's even turning a profit now. mino she mostly also lives in the region and uses the op to tend to whole farm as well. she says barely a thought of all women here on a smartphone she shares her knowledge and wants to motivate other women to take

advantage of the available tools. for what i mean by the language climate change is making farming more and more difficult and we need technology to help us with this i started a self-help group for 15 women and i encourage them to use this because i've learned a lot from it and they and their families can learn a lot from it they're starting to appreciate it and see its benefits. there we. found precise developers see over $3500.00 farmers now use their free app which is so fast still only available in hindi. that number could easily rise when the watershed organization trust our online in another t.v. languages. now we may not know it but a lot of the use in our daily life from fossil fuels undoubtedly is a detriment to the bobbit plastics in the ocean or mountains of biodegradable

waste scientists have been looking for substitutes gong to be strict and sometimes they've been successful we met a professor in germany who seemingly magical things. in a working substitute for. this building is getting added thermal insulation and damp roofing from polystyrene for every year over 10000000 tons of the synthetic material are 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 and our waters. plus. this man has a plan to replace the plastic polluted since 2008. poor and his team have

been looking into an environmentally friendly alternative popcorn. similar to polystyrene phone. if it 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 research 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 maze 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 eat it and it tastes a lot like popcorn except there's no sugar or truck with of course so the taste is

a bit boring. and. the granules have been pressed together to form sheets panels with plum proceeding providing the bonding agent as opposed to synthetic chemicals this makes the material compostable and even suitable as animal fodder. for the team pioneers in the field. they also used a horse egg 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 could use it in particular in areas of india to provide buildings with

insulation from the heat or cold. houses with the panels in the walls or on the facades. or you can also use them as insulation for solid building . the. material also performs better in the flammability test 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. in this case the damage was limited to the. grandson it being singed. kalyan patch is the design in the teens. she started experimenting with popcorn 2 and a half years ago and has now many affected her 1st pieces of furniture with the

revolutionary material. and we might soon be seeing child sized chairs and tables like these replacing their plastic counterparts. when they can other children have grown out of the furniture it can be shredded and recycled to create another new material. in movement and after being replenished it can in turn be made into a new items on to be done on the object of the house have a stage where the research team is working with a number of partners in the packaging and construction industries who realize the potential only reason the poor is happy to pass on the fruits of years of research on the material. in the op he hopes to see environmentally friendly products made from pop corn 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. fossil fuels cause harm to our planet yes we all agree to that but to grow means on a large scale as an alternative to plastics we need large areas before thailand which would otherwise be used for inable crops in the real world how feasible are environmentally friendly substitutes let's ask specialist researchers in germany to find out more. the seeds of the rape seed plant healed food oil and feed for livestock. has developed

a means to combat we based on the toil it's eco friendly and could replace the plastic foil and toxic chemicals standardly used to protect crops. those men here compared to a standard total herbicide such as plastic mulch for oil and natural material that inhibits real growth would be preferable. to the. maze is a staple food in much of the world it's also the source of ethyl alcohol used as a bio fuel for cars and trucks it's said to be less damaging to the environment than regular gas so maize and rapeseed it too important natural resources. at the campus of the technical university of new nick a team of scientists want to determine under what conditions use of these resources is truly sustainable. the broom has developed contains rake seed starch and other naturally occurring substances. it can be sprayed on the ground

around crops such as vines to inhibit the growth of we. it's an alternative to the plastic mulch foil much used in farms around the world the foil helps maintain moisture in the soil and prevent. most of it is made from conventional plastic which is made from petroleum. hitching his own alternative has considerable advantages. it's made entirely of naturally occurring raw materials most are renewables and are sealed to neutral. and water. made it so reverse the tile yielding oil food feed and biofuel materials made from expanded corn might eventually replace palestine in insulation and packaging that would reduce c

o 2 emissions is that enough to make a natural result sustainable. it is not just about emitting less as. we also consider social criteria fair remuneration in the respective countries. or your regarding the agricultural context where does the maize come from from a land that is biologically high value with a lot of biodiversity or fields where old growth forests or rain forests used to be . a further criterion for sustainability is where the materials can be recycled most conventional plastics company p.t. from say bottles can't be used. but much too much plastic waste and stop littering the environment slowly crumbling into ever smaller fragments. from micro plastics can be found in the soil just about everywhere they come from a range of sources rubbish dumps and sewage sludge used as fertilizer on fields we

don't yet know what effect these particles have on the structure of soils or whether they affect. the spray on rape seed mulch by contrast eventually washes away at a predictable pace. as long as i'm up there in our materialist biodegradable plastic foil often soiled and contaminated with other chemicals and has to be disposed of or recycled with great care our material can stay out in the field. as it decomposes all that remains there are a few nontoxic seltzer to kyron they check anyway it's a home that's product deprived. there's definitely a lot to consider. before finding the wealth effect vollmer too old for substituting plastics but what if you want to look at existing supply and demand models and find a solution that big bang will make for example it has had

a long tradition of joint production and cultivation but today follows a producing excess joint and knocking about the same all of it leaving behind a huge surplus a local scientist seems to have found the well fix solution to this problem. it looks like plastic it feels like plastic but it isn't it's a plant based product. part about you like you can make had this thing it would be the pool packaging materials that could be done or more packaging material you could with the government by getting material it would be the. shopping bag single you from paying back as. khan has spent years coming up with a substitute for plastic the raw material he works with is jute from which he creates a water soluble base 40 he then adds our natural starch based binding agent. most

certainly in one part. then we use some other chemicals i'm not mentioning this chemical because that is there more part of this that if you create and then we get this. final. product which can then be made into a for oil now con is hoping that his invention dubbed the sauna will draw global interest. this is their different political and you can see that morning if you could reproduce that drop this if. you can prove that before demonic particularly embraced the 20th bond this might finally. if there is no drop or plastic here just like they perceive after a while ash is all that remains. this is

a. land where probably more jute will be grown like here the plant is the number one natural fiber grown in bangladesh it's composed primarily of cellulose the main component in sauna. party is one of 3000000 jute farmers in bangladesh what he's harvesting now only sowed 4 months ago . the climate in bangladesh is ideal for growing this crop which requires plenty of water heat and humidity. to do. the jute fibers are found inside the stands and have to be separated from the rest of the plant. it's painstaking manual labor the whole family lends a hand. once again it's not been a good year for the pharma floodwaters washed away a part of his crop and prices have dropped so he won't get as much for what he's

managed to harvest. you have to borrow money just to make ends meet. prior to that was i have no idea what will happen alternately i guess jeered and they tell me the government isn't buying much because demand from foreign markets is down so they don't offer us good prices but i have to sell it to them anyway. around 40000000 people in bangladesh make their living from jilt either directly or indirectly. the project could change their lives but. at the moment it's still at the experimentation stage. the government is funding the pilot. production at this factory. with this new machine will soon be producing a ton of sonali a day. is that maybe somebody's going to. go for

a hole or because they decide. the juice industry is one of the biggest economic sectors in bangladesh. it's viewed as a kind of national treasure closely linked with the state's founding and for many years its only export many here hopes on early could help breathe new life into the industry. the digital revolution and the big it has provided us with has given us a big push to be more and more environmentally friendly young people around the world leading this trend and are more aware and deliberate about protecting them. in the next. 50 years we met one such group of students let's take. the. military limit livable is best achieved with the help of people who live here via when using new technology to

contribute to better understanding of traffic. i would like to see the city authorities and the general public taking care of the trees. these students are applying their coding and programming skills to the development of applications and devices to make cities more ecologically sustainable. it looks relaxed but they're actually taking part in an intensive summer school at city lab . the veterans have almost doubled around us is full of technology and had microcontrollers like this you can see how much of it though both invisible and indispensable in a. every day lineups what's really well hey we want to make things with them selves . at various workshops during the 9 days of the summer school

the participants develop all kinds of ideas and inventions all in a relaxed atmosphere outside of the classroom the city lab is a venture that brings people in berlin together to work on sustainable urban development with new photos for months i like the summer school for massive we meet outdoors in the fresh air and work on a pretty interesting technology and topics. yet so much we've got in the on line you have some online lectures but now we're working together on group projects so cool when it's a misstep because everything has been remote since the coronavirus here now at long last we can work together again as the topics are interesting and something to. $54.00 students from 4 berlin universities took part in the summer school this year . this online lecture by professor colonnade was about digitalisation and sustainability she says urban development processes need to be more inclusive. and day to be made available to very different groups in society including people

who don't have much experience with the internet who can't write computer programs how can they nonetheless access data and use it to develop something new and because. most of the workshop participants are studying business information systems and are already used to working with technology and computer programs. they relish the opportunity to brainstorm and work on innovative sustainable and eco friendly projects. yeah your line on going to combine ends on up on it i've used a solar panels and a lithium battery to build a device to charge a mobile phone i'm on small run a development board and a lot order. looking spots that lets you work even when there is no external source of electricity compared to way off grid and.

among the projects developed by the students at the summer school. a new system of hydro panics for city plants and a digital map of sustainability initiatives. to did you tell us your name is there a long time digitize ation wasn't considered to be very important in germany and that includes the government it requires major investments so if you want to digitalize an entire country it takes a lot of herself says that's also the case with promoting sustainability and there's still a long way to go off as if you know me upside. these students are seizing the moment to press ahead to make land perhaps eventually the larger world smarter greener and more sustainable. the you was of science and technology can help intentional action for the good of the i hope even cottage 2 to be could use

your scientific book to help. in what a big or small town i'll leave you with that party and see you again next week until then good bye.
