Delhi's Fireworks and Air Pollution Issues

Article Summary

Summary of Key Points

Judicial Rulings and Constitutional References

Supreme Court of India:
- November 2016: Suspended licenses for the sale of fireworks in NCR due to PM2.5 levels exceeding 700 µg/m³.
- September 2017: Relaxation of suspension to protect license holders and livelihoods.
- October 2018: In the Arjun Gopal and Others vs. Union of India judgment, allowed reduced-emission "green crackers", banned joined firecrackers ("laris"), and imposed a two-hour window for bursting.
- Latest order permits next-generation joined green crackers but does not enforce a total ban, citing public sentiment.

Environmental Data and Pollution Sources

Air Quality Metrics:
- In 2025, the PM2.5 average post-Deepavali reached 488 µg/m³, highest since 2021, with hourly concentrations peaking at 675 µg/m³.
Contributors to Pollution:
- Major sources include construction dust, vehicle emissions, stubble burning, and climatic conditions. Fireworks are not the sole contributors but can cause acute spikes during severe pollution periods.

Government Schemes & Environmental Research

Green Crackers:
- Promoted by the Council of Scientific and Industrial Research-National Environmental Engineering Research Institute (CSIR-NEERI), which forecasts a PM10 reduction of 45%-60% with the new generation.
- However, actual pollution reduction gains may diminish with increased usage of these "cleaner" options.

Challenges in Implementation and Regulation

Enforcement Issues:
- The Commission for Air Quality Management has reported unauthorized sales of QR codes used for verifying manufacturer legitimacy.
- Lack of testing facilities in Delhi complicates enforcement of the regulations.
- Past challenges included police difficulties in distinguishing green crackers from conventional ones during 2018-2019.

Implications for Public Health and Policy

There is a collective need for manufacturers to transition to the formal sector and ensure regulations are practiced effectively.
Public awareness on the health impacts of fireworks must be enhanced to mitigate air and noise pollution levels during festive seasons.

Conclusion

The interplay of legal decisions, pollution metrics, and regulatory challenges highlights the ongoing struggle in Delhi and the NCR, where public health, environmental sustainability, and regulatory enforcement converge amidst the festive use of fireworks.

Summary of Langur Problem in Chhattisgarh's Devgaon Village

Background: The village of Devgaon, located in Bemetara district, Chhattisgarh, has been facing significant issues with grey langurs, which have increasingly intruded into residential areas over the past decade. Residents report frequent disruptions from langurs raiding kitchens and causing property damage.
Wildlife Protection Act, 1972: Grey langurs are protected under Schedule II of the Wildlife (Protection) Act, 1972. This act prohibits their hunting, capturing, or harming, and constitutes a criminal offense.
Incident Overview:
- Recent viral video claims that 22 langurs were killed, triggering a Forest Department inquiry.
- Villagers allegedly hired a 'hunter' for rice to manage the langur population, a move that has raised significant controversy.
- Reports suggest the issue affects around 50 villages in the Bemetara-Nawagarh block, indicating a broader regional challenge.
Community Responses:
- The village has employed a security guard to patrol the area, marking the second instance in ten years where such a measure has been taken to deter the animals.
- Residents have attempted various methods, like laying thorny twigs on roofs, to protect their property from langur intrusions.
Health and Safety Issues: Residents report physical injuries and safety concerns due to langur interactions. For instance, a 65-year-old resident injured her foot while trying to escape a langur encounter.
Contributing Factors:
- Experts indicate habitat loss due to agricultural expansion as a primary reason for increased human-animal conflicts. The destruction of natural bunds and trees has forced langurs into human habitats as they seek food and shelter.
- Effective solutions suggested include providing safe habitats for langurs to encourage them away from human settlements.
Forest Department's Role:
- Forest officials have verified claims of frequent complaints and interventions but express that numerous villagers do not consult or inform them before employing personal guards.
- The Superintendent of Police emphasized that hiring guards requires the district collector's permission, which was not obtained in this case.
Current Status: At present, the village continues to grapple with the langur issue, and frustration among residents is growing due to a perceived lack of effective solutions and support from authorities. Many feel abandoned in addressing the persistent wildlife conflict.

This case illustrates the complexities of human-wildlife interactions, the importance of wildlife protection laws, and the necessity for community cooperation with regulatory bodies for sustainable coexistence.

Wildlife Conservation Incident: Black Panther Cub Trapping in Kerala

Incident Overview:
- A black panther cub, approximately two years old, was trapped in Kulathumon, Kalanjoor panchayat, Pathanamthitta, Kerala.
- This event is noteworthy as it represents possibly the first instance of black panther caging in Kerala.
Background:
- The trapping was initiated due to ongoing human-wildlife conflicts involving leopards in the region.
- The Chief Wildlife Warden (CWW) of Kerala issued an order for cage trapping on August 5, 2025, in response to reports of a “problematic, straying leopard.”
Health and Release Protocols:
- Upon capture, the cub was to be assessed for health and subsequently released into the wild, as per guidelines stated by the National Tiger Conservation Authority (NTCA).
- Wildlife advocates have expressed concern that the cub was transferred to the zoological park in Thrissur instead of being released back into its natural habitat, arguing that the animal had only minor injuries.
Wildlife Conflicts:
- The area has reported multiple incidents of leopard sightings, dognapping, and animal-human encounters.
- CCTV footage and pug marks confirm the presence of leopards; at least four have been captured in prior years.
Expert Opinions:
- Wildlife enthusiasts and experts argue that the cub may have had no role in the recent conflicts and that adult leopards could be responsible.
- The Divisional Forest Officer (DFO) stated that the cub would be observed in the zoological park and noted the existence of leopards in the vicinity of abandoned rubber plantations, emphasizing habitat establishment.
Conservation Measures:
- The move to relocate the cub instead of immediate wild release has drawn scrutiny related to adherence to established protocols for handling captured wildlife.
- Advocacy reflects concerns for animal welfare and the practicality of post-capture integration into natural ecosystems.
Government Policies:
- The guidelines set forth by the NTCA are crucial for the management of wildlife interventions, emphasizing rehabilitation of captured animals back into their habitats.
Conclusion:
- The situation underscores ongoing challenges in wildlife management in Kerala, particularly involving leopards, human interaction, and the welfare of wildlife during conservation practices.

This incident highlights the importance of adhering to wildlife protocol and reinforces the need for balancing human-wildlife coexistence in conflict-prone areas.
