India announced a host of measures yesterday to combat the toxic smog engulfing its capital New Delhi, including spraying water over the city, restricting vehicles on the road and providing free buses.

The pollution crisis, which has shut down schools and driven thousands to hospitals, has been blamed on vehicle emissions, burning of crop stubble and the onset of winter, which traps pollutants in the atmosphere.

"Sprinkling water is the only way to bring down the dangerous pollution levels," Reuters reported Ms Shruti Bhardwaj, the Environment Ministry's official in charge of monitoring air quality, as saying. The plan involves spraying water from a height of 100m, although it was not clear how it would be executed.

The Delhi government - led by Chief Minister Arvind Kejriwal, who has referred to his city as a "gas chamber" - is planning to reintroduce the odd-even car scheme from next Monday to Friday. Under the system, cars with licence plates ending in an even number will be allowed on the roads on even-numbered dates, and cars with licence plates ending in an odd number can be used on odd-numbered dates.

To encourage commuters to use public transport, an additional 500 new buses will hit the roads next week, offering free travel. Parking fees were hiked to 80 rupees ($1.70) per hour from 20 rupees.

Meanwhile the country's National Green Tribunal yesterday rapped the state authorities for not taking action earlier. The court had banned all construction activities in Delhi until next Tuesday. It had also directed that water be sprayed in severely polluted areas and that the roads be cleaned after spraying.

This week, India's capital, which has a population of over 16 million people, has seen pollution levels spike, with the Indian Medical Association calling it a health emergency.

The Centre for Science and Environment said some of the measures the city needs include a massive augmentation of public transport, stringent monitoring of emissions in industrial estates and a transition to natural gas and clean fuels.

Meteorologists yesterday said pollution levels, though still in the severe category, were starting to come down as winds were picking up over the city, dispersing pollutants.

"As per our prediction, although it is still severe, it will drop down considerably. We are expecting it will go down further tomorrow," said Dr Gufran Beig, chief scientist at India's state-run System of Air Quality Weather Forecasting and Research. He forecasts that by Monday, PM2.5 levels - which measure the concentration of fine particulate matter in the air - would fall from 500 micrograms per cubic m currently to 240mcg per cubic m. These very fine particles are linked to higher rates of chronic bronchitis, lung cancer and heart disease.

Residents of Delhi yesterday continued to take precautions.

Mr Nikhil Pahwa, founder of mobile and digital news portal MediaNama, ventured out yesterday after days of remaining indoors, and said he wore a face mask at all times. "I have spent 80 per cent of my time in a single room with two air purifiers... Today is the first day I have stepped out since Sunday. I had a work commitment, otherwise I am not stepping out at all," he said yesterday.
