hello and welcome to a brand new episode of equally india a sustainability magazine tree in the spotlight on solutions to some of the most pressing problems affecting the in vibrant. group coming to you from new delhi dismayed over the next 30 minutes let's look at how a fishing community in mumbai has found a way to work in the cities and dirty history books why green bike taxis could be an onslaught of open pollution worldwide and how female comedians are breaking the glass ceiling you need india one performance at a time. let's look at how an indigenous fishing community in mumbai you know 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 sewer it's self is proof that the drivel has high levels of pollutants from hazardous waste but the corny community has found a simple yet ingenious solution to help breed even thrive in mumbai. the meaty river today for live deborah pollutants was once crystal clear. when the river used to be very different if we flicked a few coins and we could see them clearly.

until 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 members of the kohli 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. from . 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. i hope people stop doing those. plastic bags and i lie so much other garbage that we can't even row our boats through it at times. our path is blocked by 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 boat. sides occupied by slums to whom the polluted river

is the only source of water. the which lies 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. rule 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 coli community like nyack to fish nobody looks certainly cares everyone listens i want to ship a sense of belonging a sense of pride that it was if you do the order time or some even have photographs of party feels to me of this we were very western me but sadly nothing of that sort can be you know you it's very rare to see ones i'm going to fish on now because it's only in the harder when the fishes come in and they also really breed now there's no there's no loss of fisheries in them it is truly is

a study which has to be done you will find that we have lost almost all of it 99 percent of what the work for sure is was being awarded to 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. here they can breed and catch their own fish. it's a simple yet in genius 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 didn't make that butter i was born in 1978. up until then our families had worked unrestricted in the us 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 in must of the. there are 34 ponds today in the extreme. are known to most man by resident 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 water of the rest of the river and the lighter color of the palms where the fish are thriving. a long term solution however will be possible only once the miti is cleaned if you see them in. any words we have let's be honest. there is a plan. you know where which will allow you to become. an area for nature and nature tourism for the city. allowing the fisherman to have their stake in america. 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 deny 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 for example food shortage changes in land use practices in climate could lead to loss of fertility in soil around the world but an american company is conducting a unique experiment by moving farming underwater. are

those giant jellyfish know these balloon like biospheres apart. of the world's 1st underwater greenhouse project 10 meters below the sea the ninos garden research project looks into forms of sustainable sub aquatic agriculture what's cultivated here usually only grows on land. diver jenny from tony's you regularly tends to the 40 different plants cultivated here it looks to me frankie and brilliant they are the same time it's really hard for the scribe but by now working every day i see a project like drawing every day and i'm so proud of the outcome so far technically . this system is not a plague of all just in the sea but imagine our many elites all are 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 photosynthesis and of course no insecticides are needed 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 the role of the water verbalise are inside and so here we have over one this is the means green equals in agrees the way. the water from here to the home market is our own view. on the issues we're. growing inside. all the. rooms. on the wall there is flowing down. the small town of normally 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. the week gianni fontanes he checks the displays at the control center in order to make sure that the greenhouse the temperature and humidity levels are in order. here you can see and wanted to ring page with the save the general situation of the head littered with the map of the different biospheres and all the technology that is powered by solar energy solar panels up here and there when we'll we're trying to be completely green. this tree of life has the cables that connect everything to the outside world. to 2 gardeners normally make diving gear and they're now using some of the same technology in their underwater lab harvest time is set for september. and this

is all moves radios. and not just the letters to basil in the next biosphere over is also ready for picking their way to unique for writing. we actually got to just bees and then a very specific because all that was grown in a very specific and new system that we were trying out which is the technology to condense faster or saltwater into freshwater. johnny fontanes a 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 the other patient process they need to go through in order to survive to the situation and it's a bit heavy that there is going it's going on down there. so far the project has

cost 250000 euros so underwater basil is still a pricey delicacy but the operators plan to continue. there were i think the most garden has a lot of prose stable temperature fresh water for free and everything with all polluting. sea gardens and 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 by pollution is only one of the causes for this nearly 11000000 private cars in school to us on tribute to 6.6 percent of belize air pollution 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. and ears 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 berkeley also. 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 collated by tailor made software. that's already been tested in london.

this 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 for to 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. and understandable attitude 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 cleaner and. a general to promote is doing his bit by building in commercializing the city crusoe electric bike taxi adapted from victuals imation 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 he said doing good business. here especially popular with tourists who fail if the city towards the driver's offer. still has been operating a bike tuffy 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 with 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. or do you want to write what you happy. new you know you're not 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 a night to save his breath for all the talking he does during the tour. it's coming here from here you can get a good view of the front of the right star it's lit up nicely in the evening. by taxi enables passengers to access places close off to conventional taxis and tour buses like just park for example just to drive recovers

a distance of between 30 and 100 kilometers a day. rights are pretty high tech they were designed and built in the southern german state of bavaria by a company called bite cycle rickshaws originated in japan. 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 or should we test the motor and generic 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 cushier began building bike toxics 17 years ago he's even designed a solar powered version of. bike taxis can be found in 120 cities around the world including munich tokyo and caravan. some $200.00 by taxis are already on the streets of foreign lands. to whom one has just completed his 1st bite of the day. i says 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 passenger is. now india has a thriving stand up comedy scene and increase in a growing number of women have joined the using laughs and jokes to talk to some horn button topics previously considered taboo for public discussion many of them also have their own shows on the internet a corresponding song off probably got caught up with one of them in delhi and found out what it takes to make a box in what is to an all boys club. no ladies this is a in the power decision to buy guns and an unusual sight at a popular comedy club in the other country maybe even the people who work on them from our t.v. shows. so when this idea of the lovely. is

a woman talking topics usually considered like buying condoms i didn't get this is the way all these races are going we are going to work but i know we're going to say we're going to say. they were my brother in laws but not their. jokes about sex marriage love masculinity and had spent. 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. profession because you travel you're alone you're in front of drunk people. there's a barrier of exact didn't which is getting better no word and all too you know we were going to get so much attention just walking on the road who wants to put it up on stage and i actually do wonder tension 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 call them 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 stand comedy happening 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 challenge of that is of course more. well hyper masculine and doesn't treat me any believe in men's voices very much. but daily also provides rich material this is when he began her career as a comedian 7 years ago she encounters rampant sexual harassment and group reach on the city's 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 being i don't use a profession for a woman i was doing what i like doing. but then over a period of time we really started to notice the fitting into the action that you get from the audience i mean although artistry before you know you do you funny i'm more street or you're really boring party headquarters for the woman you course on stage you know use a cuss word there may largescale so you know he wasn't funny 30 or he wasn't funny woman failed women often are funny not bad woman wasn't funny it's the anti-woman quite frightening to write. comedians like need the also prompting a rethink among the predominant lean mean audiences i was refused. about a girl doing in a stand up comedy but the man we actually saw hope performing in. was absolutely

fantastic but good doing the comedy is something which is breaking that you don't have and they got a question she was raising across like using gone. and the review how we look at it how we look at female gender. so that is something which is interesting that. pushing the boundaries and challenging drives one joke at a time thank i hope you would many takeaways from today's show will be back next week with many more stories of innovation and the people making them possible good bye and have a wonderful week. in
