Indian subway is growing grass

The quality of the air in India has been making headlines for years. Delhi, the capital, was once named as one of the most polluted cities in the world by the World Health Organization. What if subways could help greening cities?

This is what the Indian city of Pune is trying to do by introducing its new subway into town. First of all, the subway will reduce a little the problem of the traffic in the city where more than 3 million people currently live. Second of all, the subway authorities have put plans in place to make it green. The pillars will have vertical gardens, which will serve a dual purpose:

  • The first purpose is mainly an esthetic one, it will help to add a little green in the city as an esthetic aspect
  • The second one is the one that will be able to reduce a little bit the pollution problem present in India. The gardens will purify the air and help reduce the harmful effect of pollution.

Pollution’s rate in India

According to the World Health Organization, in the top 20 of the most polluted cities, 9 of them are cities in India. PM (Particulate Matter) 2.5 refers to fine particles (2.5 micrometers or smaller in diameter), which are produced by combustion, including motor vehicles, power plants, forest fires, and some industrial processes. Still, according to the report, some cities in India have a PM that goes from 113 to 176. Way over the “fine” limit.

According to a study by the Health Effects Institute, in 2015, over a million deaths could be attributed to air pollution in India the same study says 25% of the total deaths linked to air pollution around the globe. India’s air pollution problem has steadily worsened over the past 25 years, as its economy has grown.

This is not the first time that such initiatives appear in the country. In the city of Nagpur, where more than 2 million people live, some subways are already equipped with gardens. Trials were conclusive so they are planning on expanding it to other cities in the future.
