From UPSC perspective, the following things are important :
Mains level: Vehicular Pollution;
Why in the News?
To tackle Delhi’s severe pollution and smog, the Delhi government started implementing GRAP Stage III on November 15, which bans BS-III petrol and BS-IV diesel four-wheelers in the National Capital Region (NCR) to help improve air quality.
What are Bharat Stage Emission Standards?
Bharat Stage (BS) emission standards are regulations established by the Indian government to control the output of air pollutants from internal combustion engines in vehicles.
The first standards were introduced in 1991, with subsequent updates leading to the current BS-VI standard, which came into effect on April 1, 2020. India has progressively aligned its standards with European norms, skipping BS-V altogether due to increasing pollution levels.
What is the difference between BS-IV and BS-VI norms?
Sulphur Content: BS-VI fuel has a significantly lower sulphur content (10 ppm) compared to BS-IV fuel (50 ppm), resulting in reduced harmful emissions.
Nitrogen Oxide (NOx) Emissions:
Diesel Vehicles: NOx emissions are limited to 80 mg/km under BS-VI, down from 250 mg/km under BS-IV.
Petrol Vehicles: NOx emissions are reduced from 80 mg/km in BS-IV to 60 mg/km in BS-VI.
Particulate Matter (PM): The permissible PM emissions for diesel vehicles have been reduced from 25 mg/km under BS-IV to 4.5 mg/km under BS-VI. Petrol vehicles are also subject to a new limit of 4.5 mg/km for PM.
Emission Control Technologies: BS-VI introduces advanced technologies such as Selective Catalytic Reduction (SCR) and Diesel Particulate Filters (DPF), which were not part of the BS-IV standards. Additionally, Real Driving Emissions (RDE) testing is implemented to monitor emissions during actual driving conditions.
Why have BS-III petrol and BS-IV diesel four-wheelers been banned in Delhi-NCR?
Higher Emission Levels: BS-III petrol and BS-IV diesel vehicles emit significantly higher levels of pollutants like NOx, PM 2.5, and sulphur oxides compared to BS-VI vehicles. These emissions worsen Delhi-NCR’s already poor air quality, especially during high pollution periods.
Combatting Severe Smog and Pollution: Delhi-NCR experiences severe air quality degradation during winter due to factors like temperature inversion and low wind speeds. Banning older vehicles helps reduce pollution sources and alleviates smog conditions.
Alignment with GRAP Stage III: The Graded Response Action Plan (GRAP) Stage III mandates stricter pollution control measures during critical air quality levels, including banning more polluting vehicle categories, to protect public health and comply with environmental standards.
Note: The Graded Response Action Plan (GRAP) Stage III has been implemented in Delhi-NCR due to severe air pollution levels, specifically when the Air Quality Index (AQI) exceeds 400.
What did the emission inventory say about Delhi NCR?
Current Challenges: The Delhi NCR region faces severe air quality issues, exacerbated by vehicular emissions, construction dust, and seasonal factors like stubble burning. The emission inventory indicates these pollutants contribute significantly to the city’s chronic smog problem.
Government Response: In response to high pollution levels, the Delhi government has implemented measures such as the Graded Response Action Plan (GRAP), which includes bans on certain vehicle categories based on their emission standards.
The Central Pollution Control Board (CPCB)recorded an average AQI of 494 (Severe plus category) for Delhi where the different scales and methods explain the gap.
A study by the Centre for Science and Environment reveals that:
Vehicular emissions are the largest contributor to Delhi’s air pollution, accounting for 51.5% of the city’s pollution;
Neighbouring districts add 34.97 %,
Farm fires contribute 8.19%, and
Dust particles make up 3.7 % of the total air pollution in the city.
What is the AQI Crisis in North India and What is the role of Climatic Conditions?
Northern India, particularly Delhi, is currently facing a severe air quality crisis, characterized by record-breaking Air Quality Index (AQI) levels. The AQI in many areas has exceeded 500, categorizing it as “severe-plus,” which poses significant health risks and limits visibility due to thick smog.
This year, despite a relatively pollution-free October and early November, the second week of November brought a sudden spike in toxic particulate matter, primarily PM2.5.
Weather Patterns: Inversions and stagnant air conditions have contributed to the accumulation of pollutants. The presence of a thick pollution blanket at around 500 meters above ground level has been linked to adverse local impacts when combined with regional emissions from stubble burning and other sources.
External Pollution Sources: The increase in pollution levels due to significant contributions from external sources, including emissions from nearby states like Punjab and Haryana.
What are the challenges in Monitoring AQI?
Inconsistent Data Reporting: There is confusion regarding AQI readings, with some private agencies reporting values exceeding 1,000 while official figures cap at 500. This discrepancy arises from differences in how pollutant concentrations are converted to AQI values based on less stringent national guidelines compared to WHO standards.
Dependence on External Data: India’s reliance on satellite data from NASA for monitoring fires and pollution limits its ability to independently assess air quality. There is a need for more localized monitoring using Indian satellites that can provide continuous coverage.
Lack of Comprehensive Frameworks: Current monitoring systems do not adequately account for regional cooperation or comprehensive frameworks that address transboundary pollution issues effectively. This lack of coordination complicates efforts to manage air quality across state lines.
Way forward:
Accelerate Transition to Cleaner Vehicles: Promote the adoption of electric and BS-VI vehicles through subsidies, scrappage policies, and robust charging infrastructure to phase out older, polluting vehicles effectively.
Strengthen Air Quality Measures: Enhance monitoring of industrial and vehicular emissions, enforce GRAP actions stringently, and increase public awareness to reduce pollution sources and improve compliance.
Public Health Prioritization: A health-centric approach should prioritize the well-being of citizens by implementing measures that reduce exposure to harmful pollutants, particularly for vulnerable populations such as children and the elderly.
Multidisciplinary Solutions: Addressing air quality issues necessitates collaboration across various sectors, including transportation, urban planning, and public health. This multidisciplinary approach can foster innovative solutions tailored to local contexts while addressing broader climatic challenges.

Q What are the key features of the National Clean Air Programme (NCAP) initiated by the government of India? (UPSC IAS/2020)
From UPSC perspective, the following things are important :
Mains level: Importance of Middle Eastern countries;
Why in the News?
Saudi Arabia recently hosted a summit of Arab and Islamic leaders, urging an immediate halt to Israel’s military actions in Gaza and Lebanon while addressing the broader Palestine issue.
What were the key outcomes of the Riyadh summit on the Gaza conflict?
Condemnation of Israeli Actions: The leaders from Arab and Islamic countries condemned the Israeli military’s actions in Gaza, describing them as “shocking and horrific crimes,” including accusations of genocide and ethnic cleansing.
Call for Investigation: They demanded the establishment of an “independent, credible” international committee to investigate these alleged crimes committed by Israel.
Support for Palestinian Statehood: The summit urged for measures to end the Israeli occupation and called for the establishment of an independent Palestinian state based on the borders prior to June 4, 1967, with East Jerusalem (Al-Quds) as its capital, aligning with the two-state solution and the Arab Peace Initiative of 2002.
How does the summit reflect changing dynamics in regional politics?
Shift from Normalization: The summit reflects a significant shift in regional politics where Arab nations, which had previously moved towards normalising relations with Israel (as seen in the Abraham Accords), are now re-emphasizing the importance of addressing the Palestinian issue as a prerequisite for peace.
Collective Arab Stance: The gathering showcased a united front among Arab leaders in response to Israel’s actions, indicating a collective anger and a strategic pivot back towards supporting Palestinian rights rather than sidelining them for diplomatic ties with Israel.
Impact on Saudi-Israel Relations: Saudi Crown Prince Mohammed bin Salman’s strong condemnation of Israel’s actions signals a deterioration in potential normalization talks with Israel, as any future agreements are now explicitly linked to resolving the Palestinian question.
What is the possibility of the Arab World Joining the war?
Unlikelihood of Military Action: Despite heightened tensions and strong rhetoric, it is highly unlikely that any Arab nation will engage militarily against Israel. Historical precedents show that while Arab states have condemned Israeli actions, they have refrained from direct military confrontation since 1973.
Focus on Diplomatic Solutions: The current sentiment among Arab nations leans towards seeking diplomatic resolutions rather than military involvement, especially given their previous moves towards normalizing relations with Israel.
Strategic Realignment: The recent developments suggest a subtle realignment in West Asia’s strategic landscape, where Arab states may prioritize internal stability and regional cooperation over direct military engagement, even as they express solidarity with Palestine.
What can India do to resolve the Gaza conflict?
Mediation and Dialogue Facilitation: India can leverage its strong relationships with both Arab countries and Israel to act as a neutral mediator, facilitating dialogue and promoting peaceful negotiations between the conflicting parties.
Support for International Initiatives: India can advocate for a renewed focus on the two-state solution within international forums like the UN, aligning with global efforts to establish a sustainable, independent Palestinian state alongside Israel.
Way forward:
Strengthen Diplomatic Efforts: Arab nations should focus on reinforcing diplomatic pressure on Israel and the international community to address the Palestinian issue, promoting dialogue and supporting peaceful resolutions.
Support Palestinian Unity: Arab countries should work towards fostering unity within Palestinian leadership to present a coherent political front and advance their cause for statehood in international forums.

Prelims level: Western Honey Bees
Why in the News?
Western Honey Bees widely used for boosting pollination has led to unintended ecological consequences.
Now they inadvertently carry and transmit Thai Sacbrood Virus to native bee colonies.
AboutWestern Honey Bees
Scientific Name: Apis mellifera
Introduced globally for their pollination abilities and honey production. In India, they were introduced in 1983 to enhance honey yield.
Widely used in agriculture, particularly for pollination of crops like fruit trees, crops, and vegetables.
Thai Sacbrood Virus Outbreak
The Thai Sacbrood Virus (TSBV) outbreak in China and Vietnam has severely impacted honey bee populations.
In 1991-1992, a Thai sacbrood virus outbreak devastated around 90% of Asiatic honey bee colonies in South India and re-emerged in 2021 in Telangana.
The virus primarily infects honey bee larvae, leading to their high mortality rates.
As a result, the affected regions experienced significant declines in bee colonies, which in turn affected pollination services and honey production.
The movement of bee colonies for commercial pollination and honey production has facilitated the spread of the virus.
AboutIndian Bees and Their Habitat
Indian bees are predominantly Apis cerana indica, a species of Asian honey bee.
They are found in a wide range of habitats, including forests, agricultural land, and urban environments.
They thrive in areas with abundant flowers and nectar sources.
Indian bees are important for pollination, especially for local flora, and contribute to the ecosystem by supporting biodiversity and food production.
They face threats from habitat loss, pesticide use, and competition from Western Honey Bees, which may outcompete them for food and nesting sites.
Significance of Honey Bee:
Pollination and Food Security: Honey bees play a crucial role in pollinating crops, contributing to the production of fruits, vegetables, and nuts, ensuring global food security and agricultural sustainability.
Biodiversity Conservation: By facilitating plant reproduction, honey bees support ecosystem health and biodiversity, maintaining the balance of natural habitats and enhancing the resilience of ecosystems.
