Financial Times, 15 November 2018:
Air pollution in India illustrates the consequences of unregulated growth (“ How to power India”, The Big Read, November 5). Of the 20 most polluted cities in the world, 14 are located in India. In Delhi the level of small particulates (PM2.5) averages 143 microgrammes per cubic metre of air (the annual World Health Organization limit is 10). At this time of year, stubble burning by farmers produces peak levels up to 1000, equivalent to smoking 50 cigarettes a day. Such levels render Indian cities unfit for human habitation and particularly dangerous for pregnant women. Studies in Delhi have demonstrated that each 10 microgramme increase in the level of PM 2.5 decreases birth weight by 4 grams. As with smoking low birth weight results in lower IQ.
The tragedy is that no one wishes to accept responsibility. Unlike China, politicians in India have no strategy for improving air quality, and local politicians have no interest. In September the Ramphal Commonwealth Institute organised an international conference on Toxic Air and Megacities, but no delegate from the State of Delhi was willing to participate.
India seems equally oblivious to the dangers of climate change. Why would a country with up to 3000 hours of sunshine annually continue to rely on fossil fuels for 90 per cent of its energy? Prime minister Narendra Modi’s version of nationalism does not seem to include any concern for the health of the population, nor for the prospects of future generations.
