The Transcript
Contagious is a good word. Even in the times of H1N1, I like the word. Laughter is contagious. Passion is contagious. Inspiration is contagious. We've heard some remarkable stories from some remarkable speakers. But for me, what was contagious about all of them was that they were infected by something I call the "I Can" bug.
So, the question is, why only them? In a country of a billion people and some, why so few? Is it luck? Is it chance? Can we all not systematically and consciously get infected? So, in the next eight minutes I would like to share with you my story. I got infected when I was 17, when, as a student of the design college I encountered adults, who actually believed in my ideas, challenged me, and had lots of cups of chai with me. And I was struck by just how wonderful it felt, and how contagious that feeling was. I also realized I should have got infected when I was seven.
So, when I started Riverside school 10 years ago it became a lab, a lab to prototype and refine a design process that could consciously infect the mind with the "I Can" bug. And I uncovered, that if learning is embedded in real-world context, that if you blur the boundaries between school and life, then children go through a journey of aware, where they can see the change, enable, be changed, and then empower, lead the change. And that directly increased student wellbeing. Children became more competent, and less helpless. But this was all common sense.
So, I'd like to show you a little glimpse of what common practice looks like at Riverside. A little background: when my grade five was learning about child rights, they were made to roll incense sticks, agarbattis, for eight hours to experience what it means to be a child laborer. It transformed them. What you will see is their journey, and then their utter conviction that they could go out and change the world. (Music)
That's them rolling. And in two hours, after their backs were broke, they were changed. And once that happened, they were out in the city convincing everybody that child labor just had to be abolished. And look at Ragav, that moment when his face changes because he's been able to understand that he has shifted that man's mindset. And that can't happen in a classroom. So, when Ragav experienced that he went from "teacher told me," to "I am doing it." And that's the "I Can" mindshift. And it is a process that can be energized and nurtured.
But we had parents who said, "Okay, making our children good human beings is all very well, but what about math and science and English? Show us the grades." And we did. The data was conclusive. When children are empowered, not only do they do good, they do well, in fact very well, as you can see in this national benchmarking assessment taken by over 2,000 schools in India, Riverside children were outperforming the top 10 schools in India in math, English and science.
So, it worked. It was now time to take it outside Riverside. So, on August 15th, Independence Day, 2007, the children of Riverside set out to infect Ahmedabad. Now it was not about Riverside school. It was about all children. So, we were shameless. We walked into the offices of the municipal corporation, the police, the press, businesses. and basically said, "When are you going to wake up and recognize the potential that resides in every child. When will you include the child in the city? Basically, open your hearts and your minds to the child."
So, how did the city respond? Since 2007 every other month the city closes down the busiest streets for traffic and converts it into a playground for children and childhood. Here was a city telling its child, "You can." A glimpse of infection in Ahmedabad. Video: (Hindi) So, the busiest streets closed down. We have the traffic police and municipal corporation helping us. It gets taken over by children. They are skating. They are doing street plays. They are playing, all free, for all children. (Music)
Atul Karwal: Aproch is an organization which has been doing things for kids earlier. And we plan to extend this to other parts of the city. (Music)
Kiran Bir Sethi: And the city will give free time. And Ahmedabad got the first child-friendly zebra crossing in the world.
Geet Sethi: When a city gives to the children in the future the children will give back to the city. (Music)
KBS: And because of that, Ahmedabad is known as India's first child-friendly city.
So, you're getting the pattern. First 200 children at Riverside. Then 30,000 children in Ahmedabad, and growing. It was time now to infect India. So, on August 15th, again, Independence Day, 2009, empowered with the same process, we empowered 100,000 children to say, "I can." How? We designed a simple toolkit, converted it into eight languages, and reached 32,000 schools. We basically gave children a very simple challenge. We said, take one idea, anything that bothers you, choose one week, and change a billion lives.
And they did. Stories of change poured in from all over India, from Nagaland in the east, to Jhunjhunu in the west, from Sikkim in the north, to Krishnagiri in the south. Children were designing solutions for a diverse range of problems. Right from loneliness to filling potholes in the street, to alcoholism, and 32 children who stopped 16 child marriages in Rajasthan. I mean, it was incredible. Basically again reaffirming that when adults believe in children and say, "You can," then they will. Infection in India. This is in Rajasthan, a rural village.
Video: Child: (Hindi) KBS: First time, a rally and a street play in a rural school -- unheard of -- to tell their parents why literacy is important. Look at what their parents says.
Man: (Hindi)
Woman: (Hindi)
KBS: An inner city school in Hyderabad.
Girl: (Hindi)
KBS: Girls and boys in Hyderabad, going out, pretty difficult, but they did it.
Woman: (Hindi)
Woman: It was a revelation for me. It doesn't strike me that they had so much inside them.
Girl: Thank you ladies and gentlemen. For our auction we have some wonderful paintings for you, for a very good cause, the money you give us will be used to buy hearing aids. Are you ready ladies and gentlemen? Audience: Yes! Girl: Are you ready? Audience: Yes! Girl: Are you ready? Audience: Yes!
KBS: So, the charter of compassion starts right here. Street plays, auctions, petitions. I mean, they were changing lives. It was incredible. So, how can we still stay immune? How can we stay immune to that passion, that energy, that excitement? I know it's obvious, but I have to end with the most powerful symbol of change, Gandhiji. 70 years ago, it took one man to infect an entire nation with the power of "We can."
So, today who is it going to take to spread the infection from 100,000 children to the 200 million children in India? Last I heard, the preamble still said, "We, the people of India," right? So, if not us, then who? If not now, then when? Like I said, contagious is a good word. Thank you. (Applause)
The founder of the Riverside School in Ahmedabad, Kiran Sethi has launched an initiative to make our cities more child-friendly.
Why you should listen to her:
Kiran Bir Sethi's early training as a designer is clear in her work as an educator -- she looks beyond what exists, to ask, "could we do this a better way?" In 2001, she founded the Riverside School in Ahmedabad, designing the primary school's curriculum (and its building) from the ground up. Based around six "Beacons of Learning," the school's lesson plan focuses on creating curious, competent future citizens. The school now enrolls almost 300 children and has franchised its curriculum widely.
Sethi's latest project, inspired by dialogue with the children of Riverside, is called AProCh -- which stands for "A Protagonist in every Child." Fighting the stereotype of modern kids as rude and delinquent, AProCh looks for ways to engage Ahmedabad's children in modern city life, and to revamp our cities to make room for kids to learn, both actively and by example.
"It is possible to organize cities to teach usefulness, social responsibility, ecological skill, the values of good work, and the higher possibilities of adulthood."
With wisdom and wit, Anupam Mishra talks about the amazing feats of engineering built centuries ago by the people of India's Golden Desert to harvest water. These structures are still used today -- and are often superior to modern water megaprojects.

TRANSCIPT
For emotions, we should not move quickly to the desert. So, first, a small housekeeping announcement: please switch off your proper English check programs installed in your brain. (Applause)
So, welcome to the golden desert, Indian desert. It receives the least rainfall in the country, lowest rainfall. If you are well-versed with inches, nine inches, centimeters, 16 inches. The groundwater is 300 feet deep, 100 meters. And in most parts it is saline, not fit for drinking. So, you can't install hand pumps or dig wells, though there is no electricity in most of the villages. But suppose you use the green technology, solar pumps -- they are of no use in this area.
So, welcome to the Golden Desert. Clouds seldom visit this area. But we find 40 different names of clouds in this dialect used here. There are a number of techniques to harvest rain. This is a new work, it's a new program. But for the desert society this is no program; this is their life. And they harvest rain in many ways. So, this is the first device they use in harvesting rain. It's called kunds; somewhere it is called [unclear].
And you can notice they have created a kind of false catchment. The desert is there, sand dunes, some small field. And this is all big raised platform. You can notice the small holes the water will fall on this catchment, and there is a slope. Sometimes our engineers and architects do not care about slopes in bathrooms but here they will care properly. And the water will go where it should go. And then it is 40 feet deep. The waterproofing is done perfectly, better than our city contractors, because not a single drop should go waste in this.
They collect 100 thousand liters in one season. And this is pure drinking water. Below the surface there is hard saline water. But now you can have this for year round. It's two houses. We often use a term called bylaws. Because we are used to get written things. But here it is unwritten by law. And people make their house, and the water storage tanks. These raised up platforms just like this stage. In fact they go 15 feet deep, and collect rain water from roof, there is a small pipe, and from their courtyard. It can also harvest something like 25 thousand in a good monsoon.
Another big one, this is of course out of the hardcore desert area. This is near Jaipur. This is called the Jaigarh Fort. And it can collect six million gallons of rainwater in one season. The age is 400 years. So, since 400 years it has been giving you almost six million gallons of water per season. You can calculate the price of that water. It draws water from 15 kilometers of canals.
You can see a modern road, hardly 50 years old. It can break sometimes. But this 400 year old canal, which draws water, is is maintained for so many generations. Of course if you want to go inside, the two doors are locked. But they can be opened for TED people. (Laughter) And we request them. You can see person coming up with two canisters of water. And the water level -- these are not empty canisters -- water level is right up to this. It can envy many municipalities, the color, the taste, the purity of this water. And this is what they call Zero B type of water, because it comes from the clouds, pure distilled water.
We stop for a quick commercial break, and then we come back to the traditional systems. The government thought that this is a very backward area and we should bring a multi-million dollar project to bring water from the Himalayas. That's why I said that this is a commercial break. (Laughter) But we will come back, once again, to the traditional thing. So, water from 300, 400 kilometers away, soon it become like this. In many portions, water hyacinth covered these big canals like anything.
Of course there are some areas where water is reaching, I'm not saying that it is not reaching at all. But the tail end, the Jaisalmer area, you will notice in Bikaner things like this: where the water hyacinth couldn't grow the sand is flowing in these canals. The bonus is that you can find wildlife around it. (Laughter)
We had full-page advertisements, some 30 years, 25 years ago when this canal came. They said that throw away your traditional systems, these new cement tanks will supply you piped water. It's a dream. And it became a dream also. Because soon the water was not able to reach these areas. And people started renovating their own structures.
These are all traditional water structures, which we won't be able to explain in such a short time. But you can see that no woman is standing on those. (Laughter) And they are plaiting hair. (Applause) Jaisalmer. This is heart of desert. This town was established 800 years ago. I'm not sure by that time Bombay was there, or Delhi was there, or Chennai was there, or Bangalore was there.
So, this was the terminal point for silk route. Well connected, 800 years ago, through Europe. None of us were able to go to Europe, But Jaisalmer was well connected to it. And this is the 16 centimeter area. Such a limited rainfall, and highest colorful life flourished in these areas. You won't find water in this slide. But it is invisible. Somewhere a stream or a rivulet is running through here. Or, if you want to paint, you can paint it blue throughout because every roof which you see in this picture collects rainwater drops and deposit in the rooms.
But apart from this system, they designed 52 beautiful water bodies around this town. And what we call private public partnership you can add estate also. So, estate, public and private enterprise work together to build this beautiful water body. And it's a kind of water body for all seasons. You will admire it. Just behold the beauty throughout the year. Whether water level goes up or down, the beauty is there throughout.
Another water body, dried up, of course, during the summer period, but you can see how the traditional society combines engineering with aesthetics, with the heart. These statues, marvelous statues, gives you an idea of water table. When this rain comes and the water starts filling this tank, it will submerge these beautiful statues in what we call in English today "mass communication." This was for mass communication. Everybody in the town will know that this elephant has drown, so water will be there for seven months or nine months, or 12 months. And then they will come and worship this pond, pay respect, their gratitude.
Another small water body, called the [unclear]. It is difficult to translate in English, especially in my English. But the nearest would be "glory," a reputation. The reputation in desert of this small water body is that it never dries up. In severe drought periods nobody has seen this water body getting dried up. And perhaps they knew the future also. It was designed some 150 years ago. But perhaps they knew that on sixth, November, 2009, there will be a TED green and blue session, so they painted it like this. (Laughter) (Applause)
Dry water body. Children are standing on a very difficult device to explain. This is called kund. We have, in English, surface water and ground water. But this is not ground water. You can draw ground water from any well. But this is no ordinary well. It squeeze the moisture hidden in the sand. And they have dubbed this water as the third one called [unclear]. And there is a gypsum belt running below it. And it was deposited by the great mother Earth, some three million years ago. And where we have this gypsum strip they can harvest this water.
This is the same dry water body, Now, you don't find any kund; they are all submerged. But when the water goes down they will be able to draw water from those structures throughout the year. This year they have received only six centimeters. Six centimeter of rainfall, and they can telephone you that if you find any water problem in your city, Delhi, Bombay, Bangalore, Mysore, please come to our area of six centimeters, we can give you water. (Laughter)
How they maintain them? There are three things: concept, planning, making the actual thing, and also maintaining them. It is a structure for maintain, for centuries, by generations, without any department, without any funding, So the secret is "[unclear]," respect. Your own thing, not personal property, my property, every time.
So, these stone pillars will remind you that you are entering into a water body area. Don't spit, don't to anything wrong, so that the clean water can be collected. Another pillar, stone pillar on your right side. If you climb these three, six steps you will find something very nice. This was done in 11th century. And you have to go further down. They say that a picture is worth a thousand words, so we can say a thousand words right now, an another thousand words. If the water table goes down, you will find new stairs. If it comes up, some of them will be submerged. So, throughout the year this beautiful system will give you some pleasure. Three sides, such steps, on the fourth side there is a four-story building where you can organize such TED conferences anytime. (Applause)
Excuse me, who built these structures? They are in front of you. The best civil engineers we had, the best planners, the best architects. We can say that because of them, because of their forefathers, India could get the first engineering college in 1847. There were no English medium schools at that time, even no Hindi schools, [unclear] schools. But such people, compelled to the East India Company, which came here for business, a very dirty kind of business ... (Laughter) But not to create the engineering colleges, but because of them, first engineering college was created in a small village not in the town.
The last point, we all know in our primary schools that that camel is a ship of desert. So, you can find through your Jeep, a camel, and a cart. This tire comes from the airplane. So, look at the beauty from the desert society who can harvest rainwater, and also create something through a tire from a jet plane, and used in a camel cart.
Last picture, it's a tattoo, 2,000-years-old tattoo. They were using it on their body. Tattoo was, at one time, a kind of a blacklisted or con thing, but now it is in thing. (Laughter) (Applause) You can copy this tattoo. I have some posters of this. (Laughter) The center of life is water. These are the beautiful waves. These are the beautiful stairs which we just saw in one of the slides. These are the trees. And these are the flowers which add fragrance to our lives. So, this is the message of desert. Thank you very much. (Applause)
Chris Anderson: So, first of all, I wish I had your eloquence, truly, in any language. (Applause) These artifacts and designs are inspiring. Do you believe that they can be used elsewhere, that the world can learn from this? Or is this just right for this place?
Anupam Mishra: No, the basic idea is to utilize water that falls on our area. So, the ponds, the open bodies, are everywhere, right from Sri Lanka to Kashmir, and in other parts also. And these [unclear], which stored water, there are two type of things. One recharge, and one stores. So, it depends on the terrain. But kund, which uses the gypsum belt, for that you have to go back to your calendar, three million years ago. If it is there it can be done right now. Otherwise, it can't be done. (Laughter) (Applause)
To promote smart water management, Anupam Mishra works to preserve rural India’s traditional rainwater harvesting techniques.
Why you should listen to him:
Anupam Mishra travels across water-challenged India studying rainwater harvesting methods and learning from the people behind them. He presents his findings to NGOs, development agencies and environmental groups, pulling from centuries of indigenous wisdom that has found water for drinking and irrigation even in extremely arid landscapes through wells, filter ponds and other catchment systems.
A founding member of the Gandhi Peace Foundation, Mishra is working to bridge the gap between modern water management technology and india's heritage of water harvesting, so that every community is self-sustainable and efficiently safekeeping an increasingly scarce and precious resource.
"In [him] lives a spirit, of quiet service, that once existed freely in our politics and our activism, a spirit that has been completely excised from one sphere and remains gravely threatened in the other."
