Background
The problem of air pollution in Delhi is not new; its roots can be traced back to the rapid industrialization and urbanization that began in the latter half of the 20th century. The Green Revolution in the neighboring states of Punjab and Haryana, while boosting agricultural output, also led to increased stubble burning after the harvest season. This practice, combined with vehicular emissions, construction activities, and meteorological factors, has consistently contributed to Delhi's air quality woes.
The introduction of the Graded Response Action Plan (GRAP) in 2017 was a significant step towards addressing the issue in a structured manner, outlining specific measures to be taken based on the severity of pollution levels. Before GRAP, various ad-hoc measures were implemented, but lacked a comprehensive and pre-emptive approach.
Latest Developments
In recent years, there has been increased focus on long-term solutions to Delhi's air pollution. The Commission for Air Quality Management (CAQM) has been actively involved in coordinating efforts between different states and agencies. The promotion of electric vehicles (EVs) and the expansion of public transportation are key strategies.
The government is also pushing for the adoption of cleaner fuels and technologies in industries. Furthermore, there's a growing emphasis on addressing the issue of stubble burning through incentives and alternative uses of crop residue. The future outlook involves stricter enforcement of environmental regulations, increased public awareness, and greater collaboration between stakeholders to achieve sustainable improvements in air quality.
The CAQM is also exploring the use of artificial intelligence and data analytics to predict and manage air pollution episodes more effectively.
Frequently Asked Questions
1. What is GRAP, and why is Stage IV being revoked in Delhi?
GRAP stands for Graded Response Action Plan. Stage IV of GRAP is being revoked because Delhi's air quality has marginally improved to the 'very poor' category.
2. What are the key restrictions that remain in place despite the lifting of GRAP Stage IV?
Even with GRAP Stage IV revoked, restrictions under Stages I, II, and III continue. These include bans on construction and demolition activities, and restrictions on BS-III petrol and BS-IV diesel vehicles.
3. How does the improvement in air quality impact the daily lives of Delhi residents?
Marginal improvement allows for the lifting of the truck entry ban, potentially easing supply chain issues. However, continued restrictions like work-from-home and school closures for younger children still impact daily routines.
4. What is the significance of the 50% work-from-home directive for offices in Delhi?
The 50% work-from-home directive aims to reduce vehicular traffic and, consequently, air pollution. It is a temporary measure to manage air quality during periods of high pollution levels.
5. What recent developments led to the CAQM's decision to revoke GRAP Stage IV?
The CAQM revoked GRAP Stage IV due to a marginal improvement in Delhi's average Air Quality Index (AQI). However, the CAQM also expects air quality to remain in the 'very poor' category for the next three days.
6. What are the long-term solutions being implemented to combat air pollution in Delhi, as per the provided context?
Long-term solutions include promoting electric vehicles (EVs), expanding public transportation, and adopting cleaner fuels. The CAQM is also coordinating efforts between different states and agencies.
7. In the context of Delhi's air pollution, what role did the Green Revolution play?
The Green Revolution in Punjab and Haryana led to increased stubble burning after the harvest season, contributing to air pollution in Delhi.
8. How can the effectiveness of GRAP be improved?
Based on the information, improved coordination between states, stricter enforcement of regulations, and public awareness campaigns could enhance GRAP's effectiveness. Also, promoting long-term solutions like EVs is crucial.
9. What are the key facts related to the lifted truck entry ban that are important for the UPSC Prelims exam?
The key facts are: the truck entry ban was lifted in Delhi, the air quality improved to 'very poor', GRAP Stage IV was revoked, and GRAP Stages I-III restrictions continue. Also, remember the 50% work-from-home directive.
10. Why is Delhi's air pollution a recurring issue, and what factors contribute to it?
Delhi's air pollution is a recurring issue due to rapid industrialization, urbanization, stubble burning in neighboring states, and vehicular emissions. These factors combine to create a complex problem that requires sustained and coordinated efforts to address.
Practice Questions (MCQs)
1. Consider the following statements regarding the Graded Response Action Plan (GRAP): 1. GRAP is implemented solely by the Central Pollution Control Board (CPCB). 2. GRAP outlines measures to be taken based on pre-defined air quality thresholds. 3. The measures under GRAP are uniform across all states in the National Capital Region (NCR). Which of the statements given above is/are correct?
- A.1 only
- B.2 only
- C.1 and 3 only
- D.2 and 3 only
Show Answer
Answer: B
Statement 1 is incorrect because GRAP is implemented by multiple agencies under the CAQM. Statement 3 is incorrect because measures can be tailored to specific areas within the NCR. Statement 2 is correct as GRAP is based on AQI thresholds.
2. Which of the following factors contribute significantly to air pollution in Delhi during the winter months? 1. Stubble burning in neighboring states 2. Vehicular emissions 3. Construction activities 4. Low wind speed and temperature Select the correct answer using the code given below:
- A.1 and 2 only
- B.2 and 3 only
- C.1, 2, 3 and 4
- D.1, 3 and 4 only
Show Answer
Answer: C
All the listed factors contribute significantly to air pollution in Delhi during winter. Stubble burning, vehicular emissions, construction activities, and unfavorable meteorological conditions exacerbate the problem.
3. With reference to the Commission for Air Quality Management (CAQM), consider the following statements: 1. It is a statutory body constituted by the Ministry of Environment, Forest and Climate Change. 2. It has the power to impose environmental compensation on industries violating pollution norms. 3. It coordinates efforts between different states in the National Capital Region (NCR) to address air pollution. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
Show Answer
Answer: D
All the statements are correct. The CAQM is a statutory body, has the power to impose environmental compensation, and coordinates efforts between states in the NCR.
