4) Analyze the reasons behind the differences in performance of some of India’s large cities, with respect to transport related pollution.(250 words)
Why this question
Urban commuting has become one of the most energy- and pollution-intensive activities in India, contributing to increased greenhouse gas emissions. Transport sector is the third highest GHG contributor among all the sectors. On top of that, motorisation in India is happening at a breakneck speed. Thus it is important to understand why some cities have performed better while others fared poor in terms of air-quality standards, as is revealed by a recent CSE report.
Here we have to examine methodically the structure or nature of the topic by separating it into component parts, and present them as a whole in a summary.
Key demand of the question.
The question wants us to dig deep into the issue and bring out the reasons behind difference in the performance of India’s large cities with respect to transport-related pollution. It wants us to discuss what are the factors behind the decrease in air quality standards in the face of transport related pollution and how they lead to difference in performance of different cities.
Structure of the answer
Introduction– write a few lines about the role of transport sector in GHG emissions and air pollution in the form of release of NOx, SOx, CO2, CO, particulate matter etc.
- Discuss the performance of various big cities as revealed by the CSE report. E.g Delhi is most polluted, Kolkata least polluted among the 4 largest metro cities and Bhopal being the least polluted.
- Discuss the factors which decide the air pollution by transport sector and how they vary among different cities. E.g level of motorisation, travel demand based on population, share of different modes of transport (public transport, walking, cycling, and personal vehicles), average length of daily travel trips, and quality of vehicle technologies and fuels. Discuss what is lagging in each such city and what are the factors in favour of that city. Take the help of the article attached to the question to frame your answer.
Conclusion– Based on your discussion, form a fair and a balanced conclusion on the given issue.
