Delhi Breathes Easier: Winter Action Plan and Reduced Stubble Burning Keep AQI in Check

Delhi Environment Minister Gopal Rai has some good news for the capital after stating that so far this year, the Air Quality Index did not even go close to the dreaded "Severe" level. Mr Rai credited a combination of preventive measures and favorable environmental conditions for having improved the air quality of the capital.

One such measure has been the implementation of the Winter Action Plan by Delhi. This plan of action focuses on curbing pollution in several ways. "This time, efforts are being made to prevent pollution under the Winter Action Plan," Rai said. Among the measures include restrictions on construction dust, anti-smog guns, and more frequent checks on the emissions from vehicle emitters. These steps will control many of the major polluting factors that pose a threat to winter pollution in Delhi.

A more recent development was that Rai mentions a reduction in stubble-burning cases in neighboring states. The latter was among the most significant contributors to particulate pollution in winter months, and it had largely determined Delhi's air quality for years. The drop in cases reduced the risk that the air in the region would degrade quickly.

Warm temperatures and wind have played a supportive role in contributing to dispersing pollutants, from keeping AQI levels from reaching severe," Rai explained. Winds help in dispersing the pollutants while warmer temperatures reduce the effect of winter inversion in which cold air traps pollution close to the ground.

These factors, therefore, have been combining to bring about a short-term respite from the ordeal of Delhi's air for its citizens, even as the minister spoke of sustained effort toward further improvement in air quality.
