  • The fever dream of ‘technological sovereignty’

    I recently came across an initiative called “Industrial47”. Someone had shared a link to it on a group I’m part of, and when its card loaded, the image was of a nuclear weapon going off.

    I found on LinkedIn that “Industrial47” is a fund with the aim of “backing the forerunners of India’s Industrial Revolution”. I must say it’s quite dubious to read about a country-specific “industrial revolution” more than two centuries into a global post-industrial era. But maybe historical accuracy isn’t the point here so much as the josh elicited by those words. By this time, another member of the group had pointed out that all of India’s nuclear tests had been underground and that the one in the image depicts an American test.

    Where technology meets people

    According to its official website, Industrial47 currently funds companies developing technologies of the future. Why then did it have the image of a nuclear weapon going off? And why is there to be an Indian “industrial revolution”? *scrolls down the website* Here’s an answer — what looks like a mission statement. Let me annotate it.

    We believe India’s moment is now.

    Okay.

    Our engineers aren’t just coding software anymore – they’re designing satellites, building robots, revolutionising agriculture, reimagining defence and rethinking energy.

    There are five items listed here. The first two are factually accurate, the last two are unfalsifiable, and the third one is misleading. There’s no agricultural revolution. Let’s talk when it happens.

    They’re tackling challenges that will define the next century of human progress.

    Okay.

    The problems we solve here will ripple across eons. The companies we build here will transform billions of lives.

    The technologies we pioneer here will reshape what’s possible.

    It’s not clear where “here” is, but okay. Also there’s a grammatical problem: “The problems we solve here will ripple across eons” seems to say the problems will ripple across eons, not the solutions.

    This is more than a story of one nation’s rise. This is about humanity’s next giant leap.

    When software meets steel, when code meets craft, when bits meet atoms – therein the future is forged.

    And Industrial India will build out the next century.

    See, now there’s a problem.

    Since listening to a talk by Gita Chadha in 2020, I’ve been wary of the idea of “genius”. Among other things, I’ve noticed that there aren’t nearly as many “geniuses” in the social sciences and humanities as there are in the natural sciences. All these enterprises are littered with very difficult problems waiting to be solved but the idea of “genius” — as and when it is invoked — seems to apply only to those in the natural sciences. Even in the popular imagination, a “child prodigy” is expected to become a gifted mathematician or scientist, not a gifted poet or anthropologist. Great intellectual ability is preordained to be devoted to problems in science. Sometimes I amuse myself with the idea that problems in the social sciences and humanities simply overwhelm this “genius”.*

    If the “future” of a country is to be “forged” at the moment “when software meets steel, when code meets craft, when bits meet atoms”, and without room for where technologies meet people — which technologies, which people, when, how — it sounds like a project that expects the socio-economic and the political pieces of the “future” to fall in place in accordance with the engineering goals alone.

    You’re reading it wrong, you say. The fund only claims the future will also be forged in the solutions to engineering problems. We shouldn’t overlook these problems. I reply: Are you sure? Because I don’t see a fund to solve problems like increasing people’s trust in EVMs, improving MSPs for farmers or ensuring machines, not people, clean sewers (and I mean everywhere and in practice, not just in isolated pilot projects). How about putting the best minds together to work on the problem of developing a socio-political ideology to ultimately restore a politics of dignity and common welfare? It’s nasty, arduous, wicked work but it’s also the ultimate challenge — one that, if it succeeds, would obviate the need for most of these other interventions. But if you’d rather begin with a specific one: did you know there still isn’t a smokeless stove for rural India’s millions, leaving the country the world’s largest consumer of fuelwood for household use? Here’s a summary of Shankar Nair’s pertinent comment in The Hindu in February 2023 by ChatGPT; I hope it encourages you to read the whole thing:

    The launch of Indian Oil Corporation’s solar cook-stove at India Energy Week 2023 casts a harsh light on India’s ongoing efforts to transform household energy consumption. While promoted as a low-carbon innovation poised to reach three crore households and save costs, its steep price of ₹15,000 raises concerns about accessibility. This initiative echoes past efforts like the National Physical Laboratory’s solar cooker in the 1950s and the 1980s’ “improved chulhas” program, both of which failed due to poor design, high costs, and ineffective implementation despite government subsidies. The historical parallels underscore a recurring gap between state-led energy innovations and practical adoption, as well as the lack of focus on improving rural incomes, which strongly influence energy choices.

    Social ignorance is social harm

    Projects that offer new technological solutions these days to old problems almost never account for their social dimensions. They are instead left to the state. Isn’t this cynical? Last year’s controversy about using satellite data to track farm fires offers another good example — as does the overarching endeavour to stamp these fires out. When a new project starts up, it may advance the technology, have some companies make money, and they all move on. The socio-political and socio-economic needles almost never move. The problem of scale matters as well because of the financial implications inherent to the economic relationships between people and their technologies. At this stage of development, it is hard to give every new scheme and fund the benefit of the doubt when it ignores the question of minimising social harm and maximising social welfare. In fact, it seems like an expedient exclusion.**

    Air-purifiers come to mind. Researchers have found links between air pollution on one hand and biological and psychological development on the other. (Update, 9.10 am on January 15, 2024: Nature has just published a news feature entitled ‘Air pollution and brain damage: what the science says’.) In New Delhi (or any city with foul air for that matter), clean air is becoming increasingly vouchsafed for those with air-purifiers, which cost a good deal of money, require constant power supply, and of course owners that can pay these bills. The better and the more numerous the air-purifiers around you, the cleaner the air around you is, and the lower your risk of impaired biological and/or psychological development. Over time, people that can afford these living conditions — typically the “upper class” and, almost inevitably, “upper caste” lot — accumulate the benefits of clean air whereas those that can’t accumulate the ill-effects, and thus the gap between their fortunes slowly but inexorably widens. Every time the AQI crosses some headline-worthy threshold, New Delhi breaks out the “smog towers” and the “mist cannons” and home-appliance companies advertise newfangled air-conditioners and air-purifiers whereas state-led attempts to move towards a future in which no one needs air-purifiers flop. If I’m cynical to doubt initiatives like Industrial47, what would you call this?

    Technologisation isn’t implicitly virtuous: to succeed in the fullest sense of improving the quality of life of all Indians, it needs specific social and political conditions as well. “1947 marked our political independence, 2047 will mark our technological sovereignty,” Rahul Seth, the person behind the Industrial47 fund and “an Infantry Officer with the Indian Army Reserves” with the rank of major, wrote in a LinkedIn post (whose card displayed the nuke test). His comment and its rapturous reception assume a clean break between political and technological achievement when in fact there’s no such thing.

    Indeed, the comment is reminiscent of China’s rise as a “scientific superpower”. Part of this supposed achievement is founded on the slew of sophisticated and expensive scientific experiments it has executed, often in collaboration with other countries; its accelerating space programme; and its rapid industrialisation of the energy sector. The country is now planning to build the world’s largest hydroelectric-power dam on the Yarlung Tsangpo river, which becomes the Brahmaputra when it subsequently enters India. Until this new dam takes shape, China’s Three Gorges dam will continue to hold the torch of physical magnitude. I hope by now the dangers of building dams in the Himalaya should be clear enough to discourage unbridled enthusiasm for projects of this nature. This said, many have marvelled at the Three Gorges dam and what they claim it says about China’s ability to plan and execute such projects: as if flawlessly.

    But the country’s surveillance and censorship apparatus hampers us from knowing how people on the ground suffered as they were forced to make way for the monstrous facility. Attesting to such concerns are anecdotes that have managed to escape plus informed scholarship (see here and here, for example). Frankly, I prefer the amount of friction local movements in India have brought to bear on new “development” projects in the country. Friction is good: it ensures project proponents think twice about what they’re doing if they already haven’t. And increasingly often, they haven’t, and why should they when the current national government seems to be doing its damnedest to dilute the friction? The LinkedIn post goes: “You can be the right person, in the right place, at the right time – and yet have a few key pieces missing. Leonardo da Vinci had Lorenzo de’ Medici. Walchand Hirachand had the Kingdom of Mysore. Chandragupta Maurya had Chanakya.”* To this I’d add: India once had friction, then squandered it.

    When do we become scared?

    The quip about “technological sovereignty” rankles in this regard. On any day ‘sovereignty’ is a powerful word, not one to be invoked in vain. Here, the term fantasises a future in which technology reigns supreme, but its framing also leaves open the question of India’s place in the comity of nations, which the country has worked hard to attain, continues to build on even today, and will for the foreseeable future. Recall that obnoxious piece on NASA Watch where a former JPL science-worker called NASA’s decision to downsize JPL’s workforce — due in part to budget overruns by the Mars Sample Return mission — the “fall of a civilisation”. It was reckless fear-mongering: among other things, NASA, and the US by extension, are currently more beneficiaries of an international collaboration than patrons of the spacefaring world. “In this milieu, harping on sole leadership because it’s the ‘American way’,” as the science-worker insisted it was, “is distasteful” (source). In the same vein, consider the example of ISRO’s forthcoming space station and Indian-on-the-moon plans. Its scientists and engineers are working hard but what are they working towards? Prime Minister Narendra Modi issued orders from on high to ISRO to build the ‘Bharatiya Antariksh Station’ by year X and land an Indian on the moon by year Y. And then what? We wait for the next diktat?

    Imagine a future 50 years from now when it’s possible there are a few space stations in orbit around Earth and maybe even the moon, and when it’s plausibly (and relatively) more affordable, and not just in economic terms, to send people to stay and work there than to build a station of one’s own. Imagine if India owned and operated one of these stations instead of Indians having to lease time on another, you say. I reply: Sounds good, but where’s the cost-benefit analysis to this plan? Because unless you can demonstrate the benefit, we’re riding the coattails of speculation here and, importantly, you’re motivated by little more than the idea of Indian leadership rather than a proof of leadership de facto.

    It’s reminiscent in turn of the International Conference on the Peaceful Uses of Atomic Energy in 1955: it was chaired by Homi Bhabha, a representative from India, then a country that didn’t have nuclear power of its own. Conferences are not countries, you say. And leadership doesn’t demand “steel”, “craft” or “atoms”, I reply. This is in fact what the comity of nations allows us: leadership in various forms, and freedom from the tunnel vision that condemns the country to just one. The aspiration to “technological sovereignty” rankles specifically because, taken together, it offers one pointless pinnacle at the expense of others, and without the requisite justification of its presumed supremacy.

    The image of the nuclear weapon slips back into view. It’s from a promotional video in Seth’s LinkedIn post. It opens with a staccato montage of the Indian flag atop a temple tower, atop a mountain (Kargil?), atop the Red Fort, atop a glacier (Siachen?), and atop the moon.*** Perhaps the fund’s ultimate priority is national security, yet “technological sovereignty” implies even greater ambitions — as do other visuals in the video**** and the enterprises Industrial47 has already invested in. National security also exists today in a baleful avatar. Rather than inculcate something the armed forces deem worth fighting for, the government’s narratives have often attempted to cast soldiers’ “spirit and courage” themselves to be the objects of desire, the thing citizens at large must prove they deserve. The government has also invoked national security as a spectre, bolstered by periodic allegations of threats to Hindus, disinformation about the intentions of Muslims, and in general the communalisation of public life, to deny requests under the RTI Act about information as benign as the designs of scientific spacecraft. Unspecific appeals to national security have also become the basis for jailing students and academics for indefinite periods of time, expel foreign journalists, rebuke foreign governments’ comments on the country’s “internal affairs”, and deny the findings of international democracy and welfare research organisations. If this is national security, I sincerely dread a deeply technologised form.

    It’s just a video, you say, and you’re seeing meaning that isn’t there. Most of you must’ve watched Oppenheimer by now but let me call your attention to something Leona Woods asked Enrico Fermi after the world’s first nuclear reactor went critical: “When do we become scared?” Call it the naïvety of eggheads or political premeditation, Oppenheimer et al. had control of the Bomb until suddenly they didn’t. Its very existence reshaped the world order. Whether or not it actually went off was secondary. This is scope creep: when the parameters of a project are changing so slowly as to not be threatening, until one day you realise they’ve crossed some threshold, an unforeseen tipping point, and significantly altered the scope of the project. You thought you had a hand on the wheel, and maybe you did, but the car’s almost imperceptible drift to the right now has you endangering oncoming traffic, and yourself, on the other lane. Call it pithy, call it a cliché, but science and the technologies that follow need a hand on the wheel to adjust the course of their fantasies every now and then instead of going with the flow. Politics needs your other hand on another wheel to do the same thing, considering science is already a reason of state in India. Otherwise, we’re left staring at “technological sovereignty”.

    Or maybe these are all just words trading in josh on an investment fund’s webpage — although it does alert us to one particular plausibility and renders the words more potent: “The problems we solve here will ripple across eons. The companies we build here will transform billions of lives. The technologies we pioneer here will reshape what’s possible.” When do we become scared? I don’t know, but when you do, don’t ignore it. That’s all I’m asking.


    * “Leonardo da Vinci had Lorenzo de’ Medici” and “Walchand Hirachand had the Kingdom of Mysore” — and of course a wider socio-political environment that they navigated as well, but this aside: notice the distinctive singularity of “genius”, its manifestation with problems amenable to being solved by individuals, often working alone, as was once the case in some of the sciences but hasn’t been so for more than a century — and as has more rarely been the case in the social sphere, virtually by definition.

    ** I can seem like a habitual naysayer but I assure you I’m not. I can’t get onboard with new technology + business ideas if they’re ill-conceived or if their social and political implications haven’t been thought through. If I keep saying ‘no’, it’s because I’m being met with a continuous stream of half-baked ideas. I have no obligation to put up with one every now and then.

  • Keeper of the foul air

    This city is essentially uninhabitable from November to January inclusive and barely liveable the rest of the year. Should it even remain the nation’s capital?

    I realise Shashi Tharoor is frustrated here — revealing the increasingly evident gap between what the Delhi and the Indian governments can do about air pollution and the scale of improvements on the ground — but Delhi should certainly remain the national capital. Changing this designation because the existing one has become nearly uninhabitable for four months out of 12 is to say the capitalhood of the city is the problem, not the pollution itself. Low hanging fruit but still.

    The country’s mainstream press has also been cynical enough to remember there’s an air pollution crisis only when Delhi’s air becomes patently foul, not the air in any other city. Ambient pollution in places like Guwahati and Katihar is also not concentrated in the winter months, although this isn’t to say Delhi’s air is better during the summer. If the national capital moves away from Delhi, the press spotlight will move with it, and rather than deal with Delhi’s pollution now, we’ll all deal with the new capital’s pollution a few years later.

    Then again Prime Minister Narendra Modi isn’t bound to go anywhere considering he just had a fancy new parliament built for himself.

  • Starless city

    Overheard three people in Delhi:

    When you feel the rain fall, you feel the dirt pouring down on you, muck streaking down your face and clothes. It washes down the haze from the skies and you can finally breathe clean air and the sky gets so blue. The dust settles. Some 25 drops of water fell on my car and collected all the dirt in runnels. The next morning, my whole car had brown sports of dirt all over it. But the day after the rain, the Sun is really clear and bright in a nice way. You can finally see the stars at night. Like two or three of them!

  • Reporters in Delhi should get a wintertime allowance

    Featured image credit: souravdas/Flickr, CC BY 2.0.

    I recently moved out of Delhi. The air made it easier to decide to leave. What I’ve learnt is that a source of amusement to many friends in the country’s south is actually a nightmare up north, where a five-minute stroll outside can leave you with an irritated throat, watering eyes and the feeling that something is burning its way through your nose. In the week right after Deepavali, you woke up in the morning smelling something toasty; the view through your window was always more orange than it ought to be. You couldn’t go to and return from work without feeling short of breath – irrespective of how you travelled.

    The effects of the disaster are undoubtedly classist – and sometimes more than they need to be. Recently, Delhi’s chief minister Arvind Kejriwal announced that air purifiers would be installed at a few major traffic intersections around Delhi to clean up the air. Sarath Guttikunda, a scientist and environmental activist, wrote for The Wire about how insipid the idea is. His article highlights the vacuity of Kejriwal’s desperation, that he would resort to a downstream solution that would affect so few people in the city instead effecting something upstream – at the sources – that would help everyone. What about those who can’t afford air filters? What about those who live on the roads?

    The scale of changes that will have to be implemented implies that Delhi’s wintertime pollution problem will maintain its classist manifestation for a few years at least – assuming that the changes are implemented at all. To quote Guttikunda, they are broadly to increase the quality of public transportation and reduce the amount of waste sent to landfills. Now, the issue here is that – assuming you’re a middle-class person with a job that pays 25k to 75k a month – unless your boss is perfectly reasonable and considerate (or is a Kejriwal under pressure to be seen to act), you’re not going to get time off work unless the pollution makes you really sick (i.e. enough to have you bed-ridden for the day).

    Delhi has four popular public transportation options: auto, bus, metro and cab (Ola/Uber). There are also rickshaws but they operate over shorter distances. Only the metro is immune to traffic jams; the others contribute to and are stuck in one regularly, especially when going from south Delhi, east Delhi and Gurgaon to central Delhi in the morning and the other way in the evening. If you want to get to work on time, the metro is your best option. Even then, however, given the number of stations together with the size of the city, your odds of finding a metro station that’s close to home as well as close to where you work are really low. You’re going to have to walk, or take an auto/rickshaw, through the crappy air over the course of a few arduous minutes.

    What’re these daily minutes of exposure going to do, you ask? Deepak Natarajan, a cardiologist in Delhi, has a list of diseases likelier to beset you after short-term exposure to heightened PM2.5 levels:

    1. Acute myocardial infarction
    2. Unstable angina
    3. Increased likelihood of heart attacks by 8-26%
    4. Heightened risk of thrombosis
    5. Endothelial dysfunction,

    and a host of other cardiovascular ailments. As Natarajan writes, air pollution kills more people every year than AIDS and malaria. The next time you’re walking through the smog, feel free to imagine you’re walking through a cloud of Aedes aegypti mosquitoes.

    Circling back to the fact that there are no laws securing anyone’s choice to not work – or at least to not have to visit the workplace – with that bilious overhang: consider the plight of journalists. Reporters among them have an especial obligation to spend time on the outside, and the more seasoned among whom hardly ever think about the pollution as a vocational hazard. It’s a job that requires a modicum of physiological fitness that’s simultaneously almost never discussed. In fact, the conversation is swept away by the pretext of a ‘reporter allowance’. I used to receive one at The Hindu, a Rs 1,600 to cover intra-city travelling expenses. But it could cover very little that my salary (then at Rs 30,000) already hadn’t. And this was in Chennai, where the cost of living is lower than that in Delhi.

    (Just the way poverty makes all the small, niggling issues in life seem more maddening, a rapidly shrinking set of class-sensitive solutions available to those labouring in wintertime Delhi can drive people similarly close to the edge: such as auto-drivers refusing rides to certain areas, a perpetual shortage of buses and surge pricing. We all know these are not immediately fixable, so how about doing a Kejriwal and heading downstream to check in on your local news-bearers?)

    The reasonableness and consideration of your supervisors and employers matters in this context because Delhi’s pollution becomes easier to live through the more privileged you are. And if your editor isn’t considerate enough, then she’s probably assuming pollution affects you the way it does her, which isn’t good if she lives closer to central Delhi. Many media houses*, almost all government offices and all the more-genteel things are located towards the centre, a.k.a. Lutyens’ Delhi, which is marked by open spaces, abundant greenery, its radial outlay and wide roads – all contributing to the reduced prevalence of dust. The cost of living drops as you move further away from this area (with a marked drop once you exit the radial areas). This means the hierarchy in a journalist’s workplace is likely to be mirrored by each employee’s residence’s proximity to Lutyens’ Delhi – evidently, a proximity by proxy to healthiness.

    And privilege, as has often been the case, often blinds those who enjoy it to the travails of those who don’t. In this case, it is established by having access to the following (at a cost that doesn’t burn holes in clothing):

    1. A house in a clean neighbourhood away from dusty roads
    2. Abundant greenery in your immediate neighbourhood
    3. An air-conditioner
    4. Air filters/purifiers/fresheners
    5. A car to commute in
    6. A proximate workplace
    7. Clean, well-maintained public spaces
    8. Sufficient time and/or resources to keep the house clean
    9. Affordable medicines and medical assistance

    Without access to them, daily life can be quite disorderly, unfulfilling and hard to establish a routine with – especially if you can’t really live dirty without such a state of affairs taking a toll on your productivity and peace of mind. As a result, Delhi’s pollution imposes high entry barriers for healthy living on its residents – barriers that become less surmountable the farther away from the city’s centre you are (to add to which you spend longer to get to the city’s centre). And if you’re a reporter, you’re likelier to have it well and truly harder than most others of your means, thanks (in sum) to central Delhi being cleaner, areas farther more removed from it cheaper, air pollution being easier to live through the more privileged you are, and there being no laws to secure your right to a clean working environment.

    To address these issues and even out inequities, reporters in wartime wintertime Delhi should receive an additional allowance as well as shorter and more flexible working hours. Other staffers should also be allowed to work from where they feel comfortable apart from receiving an allowance that will help cover medical expenses, to begin with. (These measures make immediate sense for online news establishments comfortable with decentralised work environments – but they aren’t to exonerate newspaper offices that are used to having everyone work out of a common newsroom.) Those who can’t or won’t should be kept mindful of what they’re asking their journalists to give up and compensate them accordingly as and when the opportunities arise. And even so, no amount of fondness or pride for situating themselves in the national capital can save journalism establishments from the steady toll the city is taking on their journalists.

    *Offices are becoming more spread out – but that doesn’t matter.

  • Beijing’s buildings make for bad breathing but the news from India is worse

    The Wire
    June 27, 2015

    Breathing in Beijing could be like passive smoking without the short-lived pleasure of a tobacco-high. Writing in The Guardian in December 2014, Oliver Wainwright described an atmosphere akin to one in the aftermath of a nuclear explosion – instead of radioactive particles and clouds of ash, China’s capital city was enveloped in a dense suspension of smoke and dust that refused to blow away. The US Embassy in the city has an air-quality monitor that automatically tweets its readings, and for more than two years now, it has been pinging “Unhealthy”. In January 2013, it briefly went off the charts. During the Beijing marathon last year, many dropped out so they wouldn’t have to pant in the smog.

    In fact, it was a sports-related concern back in 2006 that prompted officials to act. Chinese and American scientists were trying to understand how a worsening atmosphere could affect performance in the Beijing Summer Olympics, which was two years away.

    They found that fine particulate emissions from the nearby Hebei and Shandong Provinces and the Tianjin Municipality contributed 50-70% of Beijing’s overhang. To improve the air quality, this meant officials couldn’t focus simply on emissions within the city but within the region as a whole, considering the winds carrying the most pollutants flow into Beijing from the south and the southeast. However, the same administration that has committed to reduce coal-burning in and around the city by 2.6 million tonnes by 2017 will be disappointed to find out that a more immovable hurdle now stands in their way.

    NASA scientists used data from a space-borne radar to study how Beijing has grown, and how that has affected the patterns of winds blowing in the region. While the city has been expanding in all directions, large-scale constructions are still about to begin in some areas while in others, towering buildings are already silhouetted against the skyline. The lead scientist, Mark Jacobson from Stanford University, developed a technique to see how the wind blows around these areas.

    He found that Beijing has acquired an outcrop of buildings that are trapping the air within the city, caging it and preventing it from escaping as easily as it would have if the buildings hadn’t been there. Jacobson stated, “Buildings slow down winds just by blocking the air, and also by creating friction.” And because more buildings cover up more of the soil beneath them, there’s less water evaporating than before, heating up the ground. The result is that there are now parts of Beijing where the air is cooking its own dirt, within a dome circumscribed by retarded winds.

    The scientists write in their paper: “The astounding urbanisation … created a ring of impact that decreased surface albedo, increased ground and near-surface air temperatures … and decreased the near-surface relative humidity and wind speed.” The paper was published in the Journal of Geophysical Research on June 19. According to them, even if a city didn’t allow any sources of pollution to operate within its limits, “not even a single gas-powered car”, large structures and winds would result in similar impacts on the atmosphere – leave alone what’s happening in New Delhi.

    It’s worse in India

    A WHO survey in 2014 found that 13 of the 20 cities with the worst air on the planet were in India. The Economist used data from the survey to estimate that every year 1.6 million Indians lost their lives thanks to the plummeting air quality. The problem was, and is, the worst in the national capital, whose PM2.5 measure stands at 153. To compare, Beijing’s has been hovering between 100-135 in the last few days. PM2.5 refers to solid and liquid particulate matter that’s smaller than 2.5 microns. They are able to sink deep into the lungs and cause lung and heart diseases that can be fatal, so their levels are used by the WHO as indicators of air quality.

    To the southwest of Delhi are two other very-polluted cities: Lucknow (PM2.5 100) and Gwalior (PM2.5 144), while further down in that direction is Patna (PM2.5 149). All four cities have been rapidly urbanizing, often at a rate that the region’s electricity generation and distribution system hasn’t been able to keep up with. Many have been able to afford diesel generators for auxiliary power for their homes during power-cuts, and the fumes from those generators have also been contributing to lowering air quality, while their ozone emissions are among the leading reasons why rice- and wheat-crop yields have been falling, too. However, like with Beijing, the cities are also part of a more ‘regional’ assault.

    Over 40% of Indonesia’s greenhouse gas emissions are due to peat smoke. Peat is a form of partially decomposed vegetable matter, and the archipelago is home to swaths of peatland that are burnt every year to clear space for the profitable oil palms that fuel a $50 billion industry in the country. As Mike Ives reported in January 2015, the resultant smoke contains large amounts of PM2.5 that’re blown into the mainland, carried into currents that then blow across southeast Asia.

    Similarly and closer home, crop-burning is widespread in Punjab, Haryana and Uttar Pradesh despite the fact that the activity is prohibited by law in these states. They border New Delhi to the north south and east. The crop-burning came to light recently when images taken by the NASA Aqua satellite were released, in November 2013. They showed a large cloud of smoke floating over western Uttar Pradesh, “obscuring the satellite’s view of cities such as … Lucknow and Kanpur”. The petitioner who took the matter to the National Green Tribunal, Vikrant Tongad, later alleged that had the cloud not wafted over to Delhi to afflict the people of the city, the government wouldn’t have bothered to check on crop-burnings in the three states. In rural areas, the issue is compounded by the widespread use of fuelwood for cooking and heating.

    While Beijing may have a better grip on air pollution control than New Delhi does, its problems are indicative of the world’s growing centres of urbanization. As much as civil engineers and planners try to accommodate gardens and lakes into their ideas of the environmentally perfect city, the winds of change will continue to blow in just as strongly from the farms of Punjab, the power plants of Shandong and the peatlands of Indonesia. The problem speaks to the greater challenge of being environmentally conscious about all the developmental projects we undertake instead of thinking about emissions only in terms of the cars in our cities.

  • Curious Bends – air pollution, menstruation, self-admiration and more

    1. The air that Indians breathe is dangerously toxic

    “Last year the WHO assessed 1,622 cities worldwide for PM2.5 and found India home to 13 of the 20 cities with the most polluted air. More cities in India than in China see extremely high levels of such pollution. Especially to blame are low standards for vehicle emissions and fuel. Nor, for different reasons, are rural people better off. Indoor pollution inhaled from dung-fuelled fires, and paraffin stoves and lights, may kill more than 1m Indians a year. The WHO says the vast majority of Indians breathe unsafe air. The human cost is seen in soaring asthma rates, including among children. PM2.5 contributes to cancer and it kills by triggering heart attacks and strokes. Air pollution is likely to cause vastly more deaths as Indians grow older and more obese. Indoor and outdoor pollution combined is the biggest cause of death, claiming over 1.6m lives a year.” (5 min read, economist.com)

    2. In India, girls almost never talk to their coaches about period problems

    “In a country where menstrual blood is widely considered impure and inauspicious and barely 12% of women have access to sanitary napkins, how do sportswomen in physically demanding sports deal with menstruation and its taboos? How much do periods impact their games? Anju Bobby George, India’s long jump champion from Kerala, won three golds, two silvers and two bronzes at major international competitions between 2002 and 2007. And she is convinced she could have added two more medals to her kitty if it had not been for menstruation.” (6 min read, scroll.in)

    3. Wealthy Chinese kids are twice as likely to be nearsighted as the poor

    “East Asia’s high levels of childhood myopia, also known as nearsightedness, has long been a mystery: It affects as many as 90% of urban 18-year-olds. Researchers have identified possible causes including intensive studying, less time spent outside—even the Chinese language itself. And now a new study has made the mystery even stranger.” (2 min read, qz.com)

    4. Mongolians have decided the country’s future by text message

    “Mongolians received a text message last week. It asked them to reply to vote for one of two futures for the country: budget cuts and economic austerity, or the controversial expansion of copper and gold mines, which could bring in billions of dollars in foreign investment.” (2 min read, qz.com)

    5. When Indian scientists can’t show humility, what can you expect from its politicians?

    “India’s most famous and highly decorated scientist is C.N.R. Rao, a Fellow of the world’s most prestigious scientific academies, and a recipient of his country’s highest honour, the Bharat Ratna. Some years ago, an admirer decided to lobby the Bangalore Municipality to name the circle outside the Indian Institute of Science (of which Rao had been director) after the great man. Now circles and roads are normally not named after living people. But here was C.N.R. Rao in the flesh, actually present when a circle named after him was being inaugurated.” (7 min read, telegraphindia.com)

    Chart of the week

    “No one knows how long the change will take. Lots of bright ideas exist for tackling air pollution. Their widespread implementation, however, depends to a great degree on how much the public makes a fuss about inaction. As lorry drivers might say, honk please.” (More on economist.com)
