a life sustaining oasis in the middle of an unbelievable place whether in an added desert or even the idea of a settlement on the cool dry red mars hooman is have always tried to transform inhospitable landscapes into places where they can thrive this week we'll explore how these manmade or e.c.s. affect both nature and us humans this is eco india and on some of that are cool water lilies totals from ducks sneaks dragonflies and even minnows imagine if one has to clear to cool for all these species to try a group of deadly bees scientists has created a wetland which is an area between dry land and

a water body in the north of the city to provide in the leases for the region's biodiversity let's take a look at what impact this has had. the main thing on today's to do list for another gardener's biodiversity box is picking water hyacinth it is a relaxing job but it is crucial for the survival of these wetlands and northern valley. they're going to the water hyacinths may be beautiful to look out but they are a major best in india the accord to plants are originally from the amazon basin but are now some of the most deadly invasive in native ecosystems in south asia. yes a. german other bandied about that. the water flowing with the water from the yemenite have all the plant spreads very rapidly intense to cover the entire surface of the

water that stop sunlight trump an interesting down to the bottom. i do know all the plants tend to die and the in the water creatures including fish and other marine animals perish because there is not enough oxygen to survive sunlight. ok you need a meal and your body. all the work that goes into sustaining life in the park is overseen by colleges dr for yards. off to the delhi development authority acquired the area in 2002. was instrumental in transforming it from the bottom land it was into a thriving but then eco system. anything when we came here there was a small depression we had we had i find for my case one of these. this week you can you get an indicator that this is what he called historical back land which has

been filled up for sale. but says to the subsonic if it is very high. i didn't know that about you concede that it was a bit planned once upon a time it was found. to reverse this process and this team took a gentle approach to landscape the 100 acres of land so that slopes an embankment garden green water and runoff and retaining me. based on the harvest and loads in the land to develop 2 distinct dots here each of which gets unique visitors thought this is for divers especially the birds. coming here they are divers and in medicine of the 20 you get a batter's and since last 56 years after its creation of that with lime where we have restored one of the beautiful forest community that is. it was.

really a story now every year. you get more than. many and . some of the most productive natural ecosystems they don't just happen but also help in the mundane and some water levels they leave was once dotted with these wetlands that help recharge groundwater fires as well as. those flood waters every year they also help unify the water and by mandela say the loss of limbs is very closely connected to the water problems they face. residents in me right next to the biodiversity park don't have water but have to use hand pumps to extract water out of the ground they have noticed that the new butler has made a significant impact. and

they never look clean since the great plains where established sometimes they don't 2007. and within a few years are. looking dirty all the time. with. the ecosystem biodiversity functions on its own but it also benefits from an occasional helping hand the gardeners are now planting german in origin trees here to ensure that indigenous species flush they are better at retaining water and for the overall health of the ecosystem.

even the least welcoming can be turned into a home in the last week for example residents are always trying to push the limit the island of speed. is one such and the only permanently populated island in the region and american ships is now attempting the un pink over these growing fresh vegetables for the local community that lives without sunlight for 3 months of the . finally a little light every day in winter the darkness here stretches on for months it's minus $25.00 degrees celsius and the ground is permafrost there are more polar bears than humans on spitsbergen. but one of those humans benjamin did mark rose herb's and vegetables here a pioneering idea. this one i think looks good too and then this 13. 4 the 4th one is on the 3 of us then maher and his employee hey good harvest the

crops grown in the lab as he calls this room. it has an almost tropical climate in the midst of a frozen wilderness and he's planted cress basal and other plants see that we've got the human now off to remove the tower and. yet because we lift it from 20 to 45 yeah definitely. they're learning to farm in these extremes by trial and error there's no experience to draw on then mark came up with the idea because he was desperate for fresh produce one day he even hopes to grow some tomatoes they would be the northernmost crop of them on earth. it's pitch black here by 3 in the afternoon benjamin's used to that by now. he's originally from florida but 10 years ago the ship's cook washed up on the shores of the icy no region island actually enjoy the dark season but so how do we cope with the light

season as that's the challenge but the dark season is very relaxed don't have to do too much but when the light comes. we get very busy and you have to run all of the time. whether dark or light vid mars business is booming he's barely able to keep up with demand and capacities are limited spitzbergen is located nearly a 1000 kilometers north of the next populated settlement practically everything has to be flown in including produce this other stuff but that's expensive and bad for the environment or some greens for you. so big maher is trying to show that there are other options. talk to other chefs who also. listen to him and this is probably good to. live in for sure you know. it's amazing to. this for sure but give them all back benjamin collects the leftover plant material for composting

thank you everybody should take care of you because yes thank you. this isn't a u.f.o. it's the gardener's greenhouse in the darkness of the polar night it's 20 below in here but when spring brings back the light it'll turn lush and green we have some days you know with the midnight sun there's sun in theory 24 hours a day so it just moves around in the sky and it can get like $2530.00 degrees in here i really like to do some root vegetables carrots potatoes would be nice. german student on a capsule helps out with planting in the garden she's a little more critical of the settlement in the far north. it's been present in mining disputes back and kind of personally i don't see spitzbergen as a place where people should be living. because it's gone such an extreme climate and it's so i'm sustainable to live here but there will never come

a time when people don't live here so i think it's a very good idea to try growing your own plants here. but harbaugh says it's about more than just having fresh vegetables on spitsbergen. this technique that we developed here can be used to grow food in this inner city it can be used to grow food on different islands so it has many. applications to other places as well so if we can do it here it can be done anywhere this is the most challenging place to do it. benjamin vidmar believes that if his ideas can take root in spitsbergen they could grow practically anywhere. environmentalists destruction and pollution forces people would like to find creative solutions to sustain their traditional livelihood and indigenous fishing community in mumbai came up with the simple but effective idea by creating small. pools of clean water for fish to breathe unhindered in the city's most polluted.

the meaty river today for live deborah and pollutants was once crystal clear. in the river used to be very different if we flipped a few coins and we can see them clearly. for generations coley and his family who are 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. 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. 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 china and waste recycling. people throw all kinds of things into the miti river household appliances even biomedical waste 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 was so much other garbage that we can't even row our boats through it at times. our pay. blocked by large chunks of garbage floating around.

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. 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 may want to shout but i was born in 1978. i've 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

. land was reclaimed to accommodate them there was no space for us to fish the 1st ponds in the community were built there and in must of the. 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 ponds where the fish are thriving. it's fisherman like vinayak kohli who are making a difference at the grass roots. a long term solution however will be possible only once the miti is cleaned. the advantages of green havens are undeniable foxwoods and gardens give people food for physical activity

relaxation or even an escape from the heat the spanish city of barcelona is taking action to create more resting places like this not only for people but also for insects and animals let's see how. cradle to between lush ills and the mediterranean sea barcelona is a spain's 2nd biggest city. millions of people come here every year not only to enjoy the city's unique flair but also. to visit world famous buildings such as the family law and the south africa media both designed by architect antoni county. but now barcelona could also become famous for its green ambitions by 2030 the city council's urban ecologists are looking to create an additional $160.00 hector's of green spaces that's one square meter per resident as well.

it's a very ambitious plan that will take a lot of effort but local residents will benefit from these green spaces which will also help absorb pollutants and regulate temperatures up in the build up a turning point that is much needed during recent decades barcelona's average temperature has risen by more than 2 degrees celsius now the city is looking to tackle the issue with a change in mindset and a range of green projects at the central glorious square that involves digging deep the busiest traffic junction in the city has become a major construction site soon cars will be diverted into underground tunnels and to the surface will be transformed into green parks. and for that we want to move away from the use of private vehicles and create an environment that makes it easy to walk or go by bike or public transport.

but a key player in the strategy to ease the effects of climate change will be an increase in the number of vertical gardens and the fountains of rooftops that were once a place where neighbors would meet to drive their clothes and habitat for one but another martine they are a game changer. back then the. bus alone as infrastructure is already built so it would be hard for us to fit in new gardens now we're. going on terraces rooftops and facades are some of the only opportunities that are left for us as a city. before the roof can undergo such a transition the structure of the buildings needs to be checked and apartment owners have to contribute financially to the project but the city authorities are choosing plants that are extremely heat resistant and only need a little water that ideally is provided by rainwater collected in tanks the new

greenspace can reduce the heat on the roof by up to 50 percent cooling down the apartments below and reducing the need for air conditioning as well as heating bringing nature to barcelona is a huge undertaking. this is about creating resilient spaces that can cope with the disruption that climate change is causing green spaces both private and public ones are really important and that's why we need to commit to policymaking that ensures the green areas in the city increase. soon it may no longer be necessary to climb the hills if you want to get some fresh air and enjoy the beauty of nature. deforestation and the loss of habitat of wild animals is a global issue often forest land is exploited and abandoned after many years of intensive cultivation leaving the loss of soil fertility

a couple of the western caucus proved that it is possible but don't such a waste land into a flourishing forest to get. an eel and pamela malhotra regularly check the camera traps it allows them to monitor even the extremely shy leopard. more than $200.00 endangered species live in their sanctuary called the save animals initiative it covers 1.2 square kilometers of forest in southern india. it's the. life's work about 25 years ago the couple began to buy land here piece by piece with their own money. what was here in 95 were basically plantation lands or abandoned rice fields many areas were relatively barren of any

type of tree cover because of having had coffee growing on them. today what is here now all of those lands have basically recovered they created india's 1st private protected area and reforested it on a large scale. this is also what we have gone to along with thousands of all good sapling and different going to preach. that they might mean to do trees good this area. we have had a number of scientific studies done within the sanctuary grounds and native trees soak up much more carbon dioxide than the exotic stew so this helps to medicate or question the effects of climate change the man who are letting the forest grow dead trees also enrich the soil with nutrients. their pride and joy

are some centuries old rain forest giants. they are fighting to grow forest in other parts of india as well they call them companies and business people to follow their lead. but all these inventive been are surrounding his dog to provide the optimum conditions for exercise i'm sure many of you run on a window facing treadmill or go for a swim at the people if you don't have access to a leak or the sea the danish capital of copenhagen has good work to a trash burning facility into well a ski slope let's see why and how. $450.00 metres of fun koeppen hill is an artificial ski slope on the waterfront in denmark capital copenhagen. without any snow so we can stay open year round.

with no mountains for natural skiing this 85 metre high slope is pretty impressive . it's a little bit to get used to the paper sometimes it really hits. you differently than the. little. bit. so maybe this is the new way of skiing in 2000 piece to. this unique ski slope was built on a waste to energy plant in copenhagen the industrial port facility but the steam here doesn't pose any health hazard this cutting edge plant numbers among the world's cleanest and most modern. of the world famous architectural firm. group helped bring the vision to life.

living 500000 people. every year. through the norway sweden. there's no possibility so. a building that is. in the middle of. whatever equipment at a shop at the base of. a conveyor. in ski lift take them out. skiers and snowboarders can show off their skills on the slalom course or in the fun park at the bottom of the slope and the surface. feels like real snow.

coming through. surface and that surface has a. lot of different materials and this was the one. skiing on snow the most copenhagen is one of europe's most environmentally friendly cities many here get around by bike car. now is meant to improve the quality of life here even more the architect's bright idea of combining a waste to energy plant and a recreational facility one of the german sustainability award and koeppen hill isn't just for skiing enthusiastic hikers in joggers can follow a trail to the top of the entire area was built for recreation and bringing people closer together. we don't need a function of the city where you have people living in one place people working somewhere else. everything have

a much more. fun city but also because instead of you having to travel to go everywhere with transportation just walk around and have all the different facilities of a city within a close distance. does koeppen hill have to stop for a copenhagen landmark in any case it does make good marks capital even greener. well. if you have an idea. tell us about it. we'd always looking for. i hope you enjoy it to be is episode we'll be back next week until then good bye.
