"(INDIAN EXPRESS) After playing odds and evens,the challenge is sustainable improvement, so that no special effort is needed in future.
• The current situation in Delhi is alarming with regard to its air quality as well as its traffic. Sustainable long-term solutions need to be implemented to make quality of life better for Delhi’s residents. It’s not without reason that the scientific and technical community is worried about the process and data points being used to gather usable information from this trial run for developing real solutions for the future.
• Air pollution is measured by many parameters, like CO and PM2.5, and India has come up with an Air Quality Index (AQI) to give an aggregate sense of how bad the air is.
• Pollution is caused by many factors, including traffic, construction dust, burning of agricultural byproducts, weather, emissions from power plants and industries.
• Therefore, more than just a vague rule that restricts traffic, we need a solution that achieves the holistic goal of better long-term AQ.
• These are: One, encouraging and incentivising clean fuel, hybrid and electric cars; two, car-pooling is a good option and special zones and lanes should be created; three, walking and cycling paths; four, restricting construction activity in winter months and obligating contractors to keep the construction area dust-free; five, vacuum-cleaning road dust; six, greening unpaved parts of roads and open spaces; seven, educating farmers about the hazardous effects of burning agricultural waste; eight, restricting the transit of trucks through Delhi and imposing heavy fines on non-PUC trucks; and last, analysing the outcome of the odd-even experiment critically and by experts. The exercise should become more technically focused and go slow on the publicity hoopla.
