Delhi this week over the next 30 minutes lets 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 along so to albany when you should worldwide and how female comedians are breaking the Glass Ceiling in india one performance at a time. But forced lets look at how an indigenous Fishing Community in mumbai is in a waiting to protect its livelihood the meteor b. Of a once the crown jewel in mumbai storm water drainage system used to be nothing more than a sewer its self this is proof that the river has high levels of pollutants from Hazardous Waste but the cordy community has found a simple yet ingenious solution to help fish breed and thrive in mumbai. The meaty river to day for live deborah and 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. Coley and his family members of the coli 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 eightys the river has taken a turn for the worse. From. The. People throw all kinds of things into the miti river Household Appliances even biomedical wastes like used syringes. They dont understand that we depend on this river for everything. In this i hope people stop doing that. And thats what i think about plastic bags and i lie so much other garbage that we cant even row our boats through it at times. Our path is blocked by large chunks of guard. Beds 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 occupied by slums for whom the polluted river is the only source of water. Dharavi which lie south of the maci is known as one of the Worlds Largest slums its 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 that it was if you. Are to be of this we are very best but sadly nothing of that sort can be you know its very rare to see ones im going to fish because its only in the harder when the fishes come in and. Theres no theres no loss of fisheries in them it is a study. Done you will find that you have lost almost all offered 99 percent of what the work for should is 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 kohlis of dharavi have manually built their own ponds forming naturally enclosed areas. They can breed and catch their own fish. Its 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 could but its a i was born in 1978. Have been told that our families had worked unrestricted in the us to ari. So when the city started urbanizing and more and more people moved here. About land was reclaims 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 estuary. Are known to most money 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 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 them if they were going on any words if we have hit rock bottom lets be honest. There is a plan to get them if 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 fishermen to have their stadium. 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 of the grass roots 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 well lose everything weve 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 fertility in soil around the world but an American Company is conducting a unique experiment by moving farming underwater heres how it works. Are those giant jellyfish know these balloon like biosphere is a part of the worlds 1st underwater greenhouse project 10 meters below the sea the ninos Garden Research project looks into forms of sustainable sub Aquatic Agriculture much cultivated here usually only grows on land. Diver jenny from tonys you tends to the 40 different plants cultivated here it looks to me. That the same time its really hard to describe but by now working every day a project like drawing every day and im so proud. The outcome so far technically. This system is not a police up all just in the sea but imagine how many early 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 photosynthesis 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. Verbalise or inside here. This is the means green equals in a greasy way. The water from here to the home market is our own view. On that i wouldnt use we are wines growing inside without any solid all the. Roots. On the wall there is flowing down. The small town of normally in North Western intially 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 in 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 situation 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 the wind well were trying to be like blue green green. This tree of life holds the cables that connect a. Everything to the outside world. The 2 gardeners normally make diving gear and theyre now using some of the same technology in their underwater lab to harvest time is set for september. This is almost 3 year old say. And not just the lettuce the basil in the next biosphere over is also ready for picking their way to unique for writing. We actually got to just basal in a very specific base all that was grown in a very specific and new system that we are 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 under water plants its 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 the situation and the lets say the heavy that there is going 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 their work i think the most garden has a lot of pros stable temperature fresh water for free and everything without 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 deal by pollution is only one of the causes for this nearly 11000000. 00 private cars and scooters on 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 indias megacity delhi was enveloped in fix smog last november its 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 theres the weather and it depends as well on how people are heeding 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. Thats just the type of problem siemens is trying to tackle at the crystal it center for Sustainable Urban Development in london here expert air pollution reports for cities across the globe are prepared using data collated by tailor made software thats already been tested in london. This tool do not start here. And we can access the data recorded by a london monitoring station. We are 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 im 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 of vehicle emits the cars are identified using londons 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. 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 asias got a head start on in 1975 singapore became the 1st city to levy an entry fee for vehicles today its 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 wont get their air quality problems sorted out if they dont start taking action on their traffic. And people are increasingly migrating to the cities a global trend siemens highlights in the crystal citys offer jobs culture hospitals its senseless to keep polluting these increasingly important Living Spaces with exhaust fumes so which city would alex and ebing house prefer to live in.
