2) India needs to develop its own emissions factor database relevant to local air pollution sources. Do you agree. Comment.(250 words)
Why this question
Air pollution is a serious issue in India and many of the world’s most polluted cities are from India. air pollution is not only a problem in Metropolitan or big cities but also in small cities, towns and even villages. in this context it is important to discuss whether there is any to develop an emission factor database relevant to local air pollution sources.
Comment- here we have to express our knowledge and understanding of the issue and form an overall opinion thereupon.
Key demand of the question.
The question wants us to express our knowledge and understanding about the air pollution problem across India. it then what was to express our opinion as to why/ why not there is a need for India to develop its own emissions factor database relevant to local air pollution sources.
Structure of the answer
Introduction– write a few introductory lines highlighting India’s air pollution woes. E.g mention about the air pollution status of Indian cities at global level.
Discuss in points as to why there is a need for India to develop its own emissions factor database relevant to local air pollution sources. E.g
- NCAP sets a target of 20-30% reduction of PM2.5 and PM10 by 2024, with 2017 as the base year for comparison.
- To achieve such comprehensive actions for prevention, control, and abatement of air pollution, NCAP requires detailed knowledge of data, research findings and time-to-time policy impact analysis.
- However, currently available knowledge on the sources of air pollution is inadequate to inform such contributions, particularly at local scale, which is a crucial input for developing city-centric strategies.
- For better implementation of NCAP, there is a need for researchers and policymakers to access robust, open-source data.
- India needs to develop a platform for reliable and timely data sharing, to understand source contribution and evaluate policy impacts at local and regional scale.
- Emissions inventory, air pollution modelling, ambient air quality monitoring, chemical characterization of pollutants and source apportionment studies are some of the conventional measures to understand source contribution and evaluate policy impacts.
- Today, except for Delhi, most Indian cities and regions lack such measures. There is minimal knowledge available for rural areas etc.
Conclusion– based on your discussion, form a fair and a balanced conclusion on the given issue.
