Sangita Vyas’ research focuses on the causes and consequences of child health and well-being in India. She is broadly interested in the politics and economics of inequality and making services work in India.
In this TEDxWalledCity2015 event, she shares the unheared and little understood reality of open defecation in India.
Sangita Vyas – TEDx Talk Transcript
India has a lot to be proud of: Its democratic tradition, its diversity, its contributions in art, architecture, and science, and yoga. But images like this one taint India’s reputation.
So why is this image associated with India?
Well, if this circle represents all of the open defecation that happens in the world, this is the fraction that happens in India. And this is the fraction that happens only in rural India.
65% of rural Indians defecate in the open. So what that means is that most of the open defecation that happens in the world happens in rural India and most rural Indians defecate in the open.
Every day 500 million people in villages in India go in the fields rather than use a toilet or a latrine. That’s bigger than the population of the United States. And this is a really important issue because open defecation is really bad for child health.
Every year, hundreds of thousands of children die in India because of exposure to the bacteria in feces. And those that survive are physically and cognitively stunted because of that exposure. This lives with them for the rest of their lives.
So why do so many people in India defecate in the open?
If it’s such a bad problem, if it’s so widespread and it’s so poor for child health, why does it persist? That’s the question that my colleagues and I sought to answer when we started our SQUAT survey two years ago, a survey of sanitation quality, use, access, and trends.
Some of you may be thinking that, “Well, India is a poor country and, you know, maybe people in India just can’t afford to build latrines.”
I visited a village in Uttar Pradesh last December, and I was walking around the village looking for a household that had a latrine. So I was wandering all throughout the village and I just couldn’t find anyone that had a latrine until I entered one hamlet, and I saw all these covered pits all over the place.
I got excited because latrines have pits and I thought that these were latrines. Until I started talking to someone who lived there. So I approached a man and I asked him whether he had a latrine. He said he didn’t.
Though I was a little puzzled and I asked him, “Well, if you don’t have a latrine, then what are you using this pit right here that’s in front of your house for?”
He said that he and his family had built this pit so that the water that they use for dish washing and cloth washing, and bathing could just flow into the pit and soak into the ground rather than going into the streets and making the village dirty.
This household could have definitely afforded to build a latrine. A latrine just has a pit with a slab in a seat on top of it. They had built most of that infrastructure already. They just didn’t prioritize one. In fact, many households in rural India don’t prioritize having a latrine.
So let’s compare India to some other countries in the world. On the vertical axis of this graph, we have the rate of open defecation in the country, and on the horizontal axis, we have GDP per capita. Each circle on this graph represents a country and the size of the circle represents the size of the population.
So there is a trend line here which means that richer countries tend to have lower rates of open defecation than poorer countries do. But India is really far from that trend line. India is an outlier.
Of the 55 countries that are poorer than India on this graph, 46 of them have a lower rate of open defecation. And these are countries that are poorer than India.
So let’s take Bangladesh as an example. Bangladesh has a GDP per capita of less than one half of India’s. But in Bangladesh, only 4% of households defecate in the open while in India 53% do. So the reason why income doesn’t really explain open defecation in India very well is because simple latrines that safely confine feces in the ground are actually very inexpensive.
So in Bangladesh, we’ll commonly find latrines that look like this. And many people use latrines like this all over the country in Bangladesh. These latrines cost about 50 dollars or 3,000 rupees.
In Kenya, people commonly use latrines that look like this. This costs even less than 50 dollars. These latrines are incredibly simple. They have a pit which is about 50 cubic feet or a cylinder in the ground of about three feet by six feet deep. And on top of that, there’s a slab with a seat in it.
Every five years or so these pits have to be emptied, and in pretty much every developing country in the world where latrines like this are used, they are emptied by hand. So the WHO recommends the use of latrines like this because they reduce the amount of germs in the environment.
And in most developing countries, latrines like this are commonly found all over the place. Except in India. In India it’s more common to find latrines that have pits that look like this. And I can promise you, my colleague, Nikhil is not a short man. So Nikhil and I met this household in Godhra last year, and we asked them why they were building a pit this large, they were in a process of constructing it.
This household told us that they wanted to build a pit that would last them a generation. So I asked them, “Why do you need a pit that lasts a generation? I mean, can’t you just build something that’s smaller and cheaper and empty it out periodically?”
They were completely astonished at this question. How could they empty a latrine pit by hand? If they did so they wouldn’t be able to go to the temple, they wouldn’t be able to perform their rituals, they would be completely ostracized from their society. That’s why they wanted to build a pit this big.
And this household isn’t unique in feeling that way. In fact, many households in rural India feel the same way. While the WHO recommends pits of about 50 cubic feet in size, what we found in a SQUAT survey is that people tend to build pits that are five times the recommended WHO pit size.
And when we asked households what they would ideally like to build, they told us that they wanted to build pits that were 20 times that size. And you can imagine pits this large are quite expensive to build, so latrines that people use in India are much more expensive than the kinds of latrines that are commonly used in most other developing countries in the world.
