intelligence is now spreading through our society they are will experts be able to agree on ethical guidelines to deal with this technology create deadly new more thomas weapons systems. in robot collapse stores aug 14th on g.w. . hello welcome to a brand new episode of equally india a sustainability magazine vivi tree in the spotlight on solutions to some of the most pressing problems affecting the and vibrant of our group coming to you from new delhi this week over the next 30 minutes next look at how a fishing community in mumbai has found a way to work in the cities and dirty history about why green bike taxis could be

an onslaught of albany pollution worldwide and how female comedians are breaking the glass ceiling in india one performance at the time. forced let's look at how an indigenous fishing community mumbai is in a waiting to perfect its livelihood the meteor devo once the crown jewel in mumbai storm water drainage system used to be nothing more than a school it's in kew self this is proof that the drivel has high levels of pollutants from hazardous waste but according community has found a simple yet ingenious solution to help fish breed and try in mumbai's dirty history of a. the

meaty river to day for live deborah and pollutants was once crystal clear. in the river used to be very different if we flicked a few coins and we could see them clearly. m 2 our livelihood depends on this we make our money by selling fish from the river so the pollution is a real problem. for generation. kohli and his family who are members of the cali ethnic group have lived and worked on the banks of the esther e. where the meaty river flows into the arabian sea in mumbai. but since the early eighty's the river has taken

a turn for the worse. and the. people throw all kinds of things into the miti river household appliances even biomedical wastes like used syringes and. they don't understand that we depend on this river for everything. so i hope people stop doing those. and that's what i think plastic bags and i learned so much other garbage that we can't even row our boats through it at times. our path is blocked by a large chunks of garbage floating around. the

18 kilometer long river is the dividing line between the city of mumbai and its suburbs. 70 percent of its banks on both sides are occupied by slums for whom the polluted river is the only source of water. directly which lie south of the maci is known as one of the world's largest slums it's a hub for small scale industries like honey and waste recycling. sewage industrial effluent and other solid waste get dumped into the river indiscriminately and end up flowing downstream to the estrie making it difficult for members of the colli community like to fish nobody looks certainly cares everyone. belong in a sense of pride if you. come. to me of this we were very us

turning are certainly nothing of that sort you know you'd say it's very rare to see ones i'm going to fish because it's only in the harder when the fishes come in and they really believe now there's more there's more loss of fisheries in the meatiest tree is a study. done you will find that we have lost almost all offered 99 percent for sure this was being the fisheries value of this tree has gone over. in view of the disastrous conditions the fishermen have taken things into their own hands using an age old practice the kohli's of dharavi have manually built their own ponds forming naturally enclosed areas.

where they can breed and catch their own fish. it's a simple yet ingenious strategy. to create the ponds the fishermen have to remove the silt by hand and down the sea water that flows into the estuary at high tide the mother going to make sure that the words are i was born in 1978. until then our families had worked unrestricted and yes to ari. so when the city started urbanizing and more and more people moved here. land was reclaimed to accommodate them a new one and there was no space for us to fish the 1st ponds in the community were built there and it must have the you know. there are 34 ponds today in the estuary. unknown to

most mumbai residents approachable only by boat and tucked away in the thick mangroves. the ponds have wire mesh is at each entrance which keep out the garbage flowing from upstream the mangroves to act like a natural barrier. the difference is stark between the innkeeper lack water of the rest of the river and the lighter color of the pond where the fish are thriving. a long term solution however will be possible only once the miti is cleaned if you see their material world cannot get any worse if we have hit rock bottom let's be honest. there is a plan to get them and they were back in nowhere which will allow me to become

a recreation area an area for nature and nature tourism for the city. allowing the fisherman to have their stadium at. the local government however has spent the last 13 years seeking to restore the miti after devastating floods back in 2005 ravaged everything on its banks but to no avail. its fishermen like vinayak kohli who are making a difference at the grassroots but often the 4th generation fisherman wonders how long this can continue. you can see all the garbage if nothing is done in the next 2 to 3 years we will lose everything we've had for generations. now like the ones protecting local ecosystems is definitely the need of the hour in

fact it could be quick to preempt problems of the future big for example food shortage changes in land use practices in climate could lead to loss of where to live in soil around the world but an american company is conducting a unique experiment by moving farming underwater here's how it works. are those giant jellyfish know these balloon like biosphere is a part of the world's 1st underwater greenhouse project 10 meters below the sea the name of those garden research projects looks into forms of sustainable sub aquatic agriculture which cultivated here usually only grows on land. diver jenny from tennessee regularly tends to the 40 different plants cultivated here it looks to me frankie. brady and the same time it's really hard to describe

but right now working every day a project like drawing every day and i'm so proud. the outcome so far technically. this system is not the police at all just in the sea but imagine our many a late solar on the war can really benefit this is them 6 years ago divers installed the 1st underwater greenhouses at this depth the sunlight is still sufficient for future synthesis and of course no insecticides needed in the surrounding sea water is treated and then used to water the plants the project is currently experimenting with various kinds of fruits and vegetables this is a wonderland we're all of the water over to the other inside here. this is the mystery. it was in agrees you weigh 100 bodies in the water from here to the top are these are all you. on the issues we are.

growing inside. the roots. on the wall there is slowing down many granted in. the small town of newly in north west initially attracts lots of tourists but hardly any of them would guess that this unique underwater lab exists just 100 meters from the beach promina. 3 times a week gianni fontanes he checks the displays at the control center in order to make sure that the greenhouse is temperature and humidity levels are in order. here you can see and wanted to ring page with the save the general circulation of the habitat with the map of the different biospheres and all the technology that is powered by solar energy solar panels up here and there when will we are

trying to be completely green. this tree of life holds the cables that connect. everything to the outside world. the 2 gardeners normally make diving gear and they're now using some of the same technology in their underwater lab to harvest time is set for september. and this is almost ready i'll say. and not just the lettuce the basil in the next bias fear over is also ready for picking though it's a unique karate. we actually got to just bees and then a very specific result that was grown in a very specific and new system that we were trying out which is a technology to condense faster or saltwater into freshwater. jenny fontanes e used to turn these leaves into pesto now scientists from the university of pisa examine the underwater plant. it's hard to say that pace is the friend or not of

course this mouse is super good but the real difference is inside of the plants because of that that station process they need to go through in order to survive to this situation and it's a heavy that there is going going on down there. so far the project has cost 250000 euros so underwater battle is still a pricey delicacy but the operators plan to continue their work i think the most garden has a lot of pros stable temperature fresh water for free and everything without polluting. sea gardens are no longer just a dream these become real projects that just might lead to more sustainable agriculture. shifting focus now if you look around me it would come is no surprise that the air quality in delhi is the worst in the world will be killer deal by pollution is only one of the causes for this

nearly $11000000.00 private cars and scooters want to be. 6.6 percent of. a german company has created a tool to help city planners mitigate the adverse effects of pollution caused by increasing traffic. just breathing normally is painful here the air is foul and burns your eyes india's megacity delhi was enveloped in fix smog last november it's a problem many cities face worldwide even if not quite as extreme as this. of course it often has a lot to do with a geographic location then there's the weather and it depends as well on how people are heating their homes and if you get a calm and stable high pressure system which happens here frequently with no wind blowing then none of the filth gets blown out of the city council. that's

just the type of problem siemens is trying to tackle at the crystal it center for sustainable urban development in london here the expert air pollution reports for cities across the globe are prepared using data collected by tailor made software. it's already been tested in london. just tool do not start here. and we can access the data recorded by a london monitoring station. and we're looking at having to take action to counteract the threat of exceeding pollution limits. of their frequently unpopular measures and this tool helps city planners to say ok i'm going to have a problem and 3 to 5 days. that would mean keeping as many cars as possible out of the city those which do enter are charged a fee which increases in line with the amount of harmful exhaust a vehicle emits the cars are identified using london's road toll system which has

been in place for 14 years right now you pay 11 pounds to enter the city on a weekday. just that they come straight off your bank account yes basically straight away and in the future that will at least double that might be even more expensive for diesel vehicles. there are no tolls in german cities something else asia's got a head start on in 1975 singapore became the 1st city to levy an entry fee for vehicles today it's $1.00 of the cleanest cities in asia. on the other hand you have to see that in india or china besides the industrial production which is going on all over the city as traffic also plays a huge role and they won't get their air quality problems sorted out if they don't start taking action on their traffic. and people are increasingly migrating to the cities

a global trend siemens highlights in the crystal cities offer jobs culture hospitals it's senseless to keep polluting these increasingly important living spaces with exhaust fumes so which city would alex and ebing house prefer to live in. here in london and london's got a huge debate going on about air pollution if i think about it probably move to the countryside. i don't understand of latitude for an expert in pollution levels in major urban centers. now this is a recurring question in the 21st century how do we make our cities. germinal to promoters doing his beat by building in commercializing the city crews are unclear electric bike taxi adapted from victuals in asian countries what's more it's a. huge it's morning time in the heart of the german capital. here at the very case by top she said doing good business. here especially

popular with tourists who fail if the city towards the driver's offered. has been operating at by touch feet for 13 years. this is a super job for me i've always loved cycling and i like to get moving and i get paid for it i'm never bored of it and i get to show people the city and they're usually really impressed with not every job is like that. he charges $45.00 euros for a tour of the city. where you want to write what you have a. new you know you're not a life you're as light as a feather. together the driver passengers and bike weigh about $350.00 kilos. if an extra boost is required there's a manually operated electric motor. that's nice to save his breath for all the

talking he does during the tour. so it's coming here from here you can get a good view of the front on the right star it's lit up nicely in the evening on. the bike taxi enables passengers to access places close off to conventional taxis and tour buses like just park for example just to drive recovers the distance between 30 and 100 kilometers a day. ikes are pretty high tech they were designed and built in the southern german state of the very a by a company called bike cycle rickshaws originated in japan by has given them a modern twist it takes 2 hours to charge up the battery for the motor. considering it can ferry 3 people 2 in the back plus the driver. has

a range of 60 kilometers it's could replace a car. bike employs 6 people. guys will surely test the motor and geneive stefan cush was designed the bike taxi a quick check to make sure everything's in order before it took over 8 years to develop the prototype. bike taxi will set you back 10000 euros. to sweeten the deal the engineer has designed a vehicle to accommodate. bike gets a small part of the cost most of the admin new goes to the driver it takes about 5 months to pay back the value of the bike taxi. stefan cush have begun building bike tuxes 17 years ago he's even designed a solar powered version. bike taxis can be found in 120 cities around the world

including munich tokyo. some $200.00 by taxis are already on the streets of fairyland. to whom one has just completed his 1st bite of the day. as a session it was really great and everything was well explained i'm sure we'll do it again sometimes it was. for to lie it's time to find his next passengers. now india has a thriving stand up comedy scene and increase and a growing number of women have joined in the using laughs and jokes to touch upon some horrific button topics previously considered taboo for public discussion many of them also have their own shows on the internet our correspondents got caught up with one of them in delhi and found out what it takes to make a bomb in water steam and oil boys club.

this is a hill the this is. an unusual sight at a popular comedy club in delhi the other going to live even though we're going to go from our. so in this idea of leveling asking all condoms is like a woman tackling topics usually considered like buying condoms for her brother and then given to those he always wishes are going with me feel like i'm going to what . they were always. they got my brother. but not that. jokes about 6 matter of love masculinity and had assumed calling out 6 of them and gender biases in the process she's well known in india's comedy circuit largely a boys' club the dissuades women from joining in it's

a tough profession because you travel you're alone you're in front of drunk people . there's a barrier of exact didn't we just getting better no word and also you know we women get so much attention just walking on the road who wants to put it up on stage and i actually do wonder tention we're taught from childhood to not draw attention to ourselves so it's very hard to get over that mindset. i think we've got a fairly decent crowd and those hurdles are all too familiar to you during the day she runs a film production company evenings the office doubles up as a venue for comedy events the difference is that the shows here are only meant to aspiring female comics delis hostile as a space for women in either sex ratio has that of the. women feeling safe enough to come out in the evening stunned comedy happy in the evenings at night even something as small as that can be a huge barrier that men never have to consider and of course jenny the baggage of that is of course more. well hyper masculine and doesn't treat me any believe

humans way says very much. but daily also provides rich material this is when the p. began her career as a comedian 7 years ago she encounters rampant sexual harassment and group reach on the city streets and channels it into such article jokes act the stories and witty one liners. at a favorite cafe it's the perfect place for observing people where he honestly when i started out movement or both this me and i knew it profession for a woman i was doing what i like doing. but then over a period of time where you start to notice the difference into the action that you get from the audience a male or a artist point me toward you know you do you funny i'm more street or you are you boy card ahead of where you're from the woman you of course on stage you know use a cuss word their male artist failed so you know he wasn't funny today or he wasn't funny woman fails women are not funny not back home and wasn't funny it's the

anti-woman guy frightening. right. comedians like need to also prompting a rethink on the predominantly mean. by was refused. about a girl doing you know stand up comedy but the man we actually saw hope performing in. was absolutely fantastic the good the doing the comedy is something which is being busy today and they got a question she was raising across like using gone. and the view how we look at it how we look at female gender. so that is something which is interesting. pushing the boundaries and challenging biases one joke at a time thanks i hope we would many takeaways from today's show we'll be back next week with many more stories of innovation and the people making them possible goodbye and have a wonderful week. economies
