Introduction:

Climate change, a formidable environmental challenge, casts an extensive impact on various elements of the Earth’s ecosystem, with air quality being a primary concern. The alteration in temperature patterns, precipitation, and an increase in the frequency of weather-related disasters contribute to deteriorating air quality, manifesting in increased pollutants and fostering health and environmental crises.

Correlation between Climate Change and Air Quality:

• Meteorological Influences: 
  • Climate change influences meteorological variables like temperature, wind patterns, and precipitation, which play critical roles in dispersing or accumulating air pollutants in the atmosphere. 
  • For instance, increased temperatures intensify the occurrence of ground-level ozone, a harmful pollutant.
• Extended Wildfire Seasons: 
  • Climate change has led to hotter and drier conditions, especially in forested regions, causing more frequent wildfires, which significantly deteriorate air quality. 
  • The smoke from these fires carries pollutants across vast distances, affecting larger regions beyond the fire zone.
• Amplification of Dust Storms: 
  • Changing climate patterns have intensified dust storms, especially in arid and semi-arid regions. 
  • For example, parts of North India face severe air quality issues exacerbated by dust storms that originate from the deserts, carrying large amounts of particulate matter.

Effectiveness of Policy Initiatives in India:

• National Clean Air Programme (NCAP): 
  • Launched in 2019, the NCAP aims to reduce particulate matter (PM) pollution by 20-30% by 2024 from 2017 levels. 
  • It brings together multiple initiatives but faces challenges in implementation, including insufficient funding, technical capabilities, and coordination between governmental bodies.
• Pradhan Mantri Ujjwala Yojana: 
  • This initiative aimed to reduce indoor air pollution by providing cleaner cooking fuel (LPG) to below poverty line families, thus targeting a reduction in the health impacts linked to poor indoor air quality.
  • It has seen substantial success in terms of distribution but still faces challenges in rural adoption due to the recurring cost of LPG cylinders.
• Afforestation Initiatives: 
  • Projects like the Green India Mission, which aims to increase forest cover, indirectly contribute to improved air quality by increasing the sink for carbon dioxide. 
  • However, the effectiveness is often marred by issues like improper site selection and the planting of non-native species.
• Odd-Even Scheme: 
  • Cities like Delhi have experimented with the odd-even scheme to curb vehicular pollution, especially during times of severe air quality deterioration. 
  • The short-term policy has shown immediate relief benefits, but its long-term effectiveness remains questionable without the support of robust public transportation.
• Renewable Energy Push: 
  • With policies favoring renewable energy expansion, India has made strides in reducing its reliance on fossil fuels, a significant contributor to air pollution. 
  • The effectiveness is ongoing, with ambitious targets; however, the challenge lies in managing the transition without compromising energy availability.

Conclusion:

The interlinkages between climate change and air quality are complex and multidimensional, necessitating a holistic approach to policy-making. While India has initiated several policies targeting the improvement of air quality, their effectiveness is contingent on addressing ground-level execution challenges, ensuring inter-departmental coordination, and securing community engagement. Moving forward, integrating climate change mitigation and air quality objectives, enhancing scientific research, public awareness, and international cooperation will be pivotal in sculpting a sustainable future with cleaner air.
