Delhi, the city once famous for the charm of the Red Fort and the elegance of Qutub Minar, is today infamous for its pollution crisis. Ranked one of the most polluted cities in the world, the air in the city is taking a toll on its residents’ health. With over 10 million vehicles registered in Delhi, it is not surprising that the air is turning toxic. But how bad is the air really in the roads of Delhi?

In the past century, fossil fuels like petrol and diesel have powered our vehicles, machines and in fact, our world! But the era of these fuels is coming to an end; all our petroleum reserves are soon ending, and the increasing pollution due to these fuels is making the world sick. Now, our hope lies in biofuels—fuels produced by organic wastes that are renewable and eco-friendly, unlike fossil fuels.

Erik Solenheim, Executive Director of the United Nations Environment Programme visited Center for Ecological Sciences at Indian Institute of Science (IISc), Bengaluru to deliver a talk about the interface of science and policy.

In his talk titled ‘Science Policy Interface: Insights and ideas for a changing world’ Mr. Solenheim spoke about the three main environmental challenges of we face today namely; climate change, pollution and loss of biodiversity.

Researchers from the Indian Institute of Tropical Meterology, Pune, study how carbonaceous aerosols affect the different layers of our atmosphere. They find that these aerosols can have far reaching effects like instabilities in the mid to upper troposphere, bringing about a change in the rainfall patterns and causing abnormal heating of the atmosphere through radiation

India today faces several challenges, an air pollution is one of the important one’s to overcome. Four Indian cities often features on world’s top 10 most polluted cities. And lack of data has prevented us from understanding effects of the pollution and take measures to tackle them. A new study now shows that one’s daily routine can be a good indicator for the level of pollution one might face.  It has already shown us that people travelling in cars and CNG buses face a lot less pollution and could help us find a lot more solutions to our pollution woes. 

India is no stranger to air pollution, with the capital, New Delhi, being identified as one of the most polluted cities in the world, several times. The harmful effects of this deteriorating air quality can be seen in the increasing number of patients with respiratory disorders. Now, a team of scientists have designed a novel gas sensor using MEMS technology that is compact, highly sensitive, consumes very little power and accurately detects gaseous pollutants like CO, CO₂, NO₂ & SO₂.

The oceans make up 75% of our Earth and is home to a wide range of plants and animals that thrive in marine ecosystems around the world. Thanks to human actions, these ecosystems face a mounting threat, far too inconspicuous, for us to observe. Ocean pollution, raise in its temperature and rampant overfishing have threatened many species and have pushed them to the brink of extinction. On World Oceans Day, perhaps it is time to reflect what roles these oceans play in helping life on the land and think about how our activities have disturbed the fragile balance nature maintains in the deep blue seas.

Scientists at the Indian Institute of Science (IISc), Bengaluru, have conducted a study analyzing the influence of socio-demographic factors on the commuting habits of people in Bengaluru. The findings of the team, led by Prof. Ashish Verma from the Centre for Infrastructure, Sustainable Transportation and Urban Planning (CiSTUP), can be implemented in metropolitan cities to ease traffic congestion and pollution by opting for alternative and eco-friendly modes of transport.
