Poor Air Quality in Mumbai
GS Paper 1
Syllabus: Geography
Source: IE
Context: Mumbai has been grappling with air quality issues, marked by prolonged periods of “moderate” or “poor” ratings on the Air Quality Index (AQI).
Mumbai’s Air Pollution:
- Air quality in Mumbai deteriorated significantly, with 66 out of 92 days between November 2022 and January 2023 categorized as “poor” or “very poor.”
- In comparison, Delhi experienced 79 days of “Poor” and “Very Poor” AQI during the same period. (Data from SAFAR – Ministry of Earth Sciences).
How Geography of Mumbai keeps it free from pollution?
Mumbai benefits from a natural cleansing mechanism due to its coastal setting. Strong surface winds prevalent in the area facilitate the rapid dispersal of pollutants. Additionally, the powerful sea breeze that sweeps across Mumbai’s landscape contributes to the removal of these airborne particles, carrying them away from the land. This coastal geography helps maintain relatively better air quality in the city, especially during most of the year when these natural processes are at work.
Reasons Behind Rising Air Pollution in Mumbai Recently:
| Factors | Impact on Air Pollution |
| 1. “Triple dip” La Niña | Last winter, Mumbai experienced an unusual “triple dip” in La Niña, related to climate change. |
| During La Niña, colder ocean surfaces absorb more atmospheric heat, leading to a cooling effect and reduced air temperature. This results in infrequent wind reversals from the sea, which usually disperse pollutants every 2-3 days. With wind reversal occurring only every 10-15 days during La Niña, pollutants remain trapped in the lower atmosphere for longer periods, worsening air quality. | |
| 2. Delay in Monsoon Withdrawal | The delayed withdrawal of the monsoon had a significant impact on Mumbai’s air quality, creating unfavourable conditions for pollution dispersion. |
| 3. Role of Transport Winds | Transport-level winds carried pollutants toward Mumbai. When they met warmer winds laden with local dust, it created a dust-filled cloud that couldn’t disperse due to calm winds, and deteriorating air quality. |
| 4. PM10 Pollution from Anthropogenic Emissions | Coarser particles, specifically PM10 (particulate matter with a diameter of 10 micrometres or less), remain a major pollutant in Mumbai. Dust emissions from various development and construction activities contribute to this issue. |
To tackle air pollution in Mumbai, the following measures should be taken:
- Prioritize long-term mitigation planning by mapping airsheds.
- Focus on reducing anthropogenic emissions, the root cause of air pollution.
- Adopt a data- and science-driven approach, relying on reliable scientific sources.
- Use green curtains at construction sites to reduce dust.
- Implement regular water spraying to dampen dust particles and prevent them from becoming airborne.
- Transition to fossil fuel-less transportation, including electric vehicles.
- Improve waste management, clean up dumping grounds, and manage industrial toxins to enhance air quality in the medium term.
What is the Air Quality Index (AQI)?
The Air Quality Index (AQI), managed by the Central Pollution Control Board (CPCB), is a crucial tool for assessing and communicating air quality in India. It takes into account eight different pollutants, including particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), ammonia (NH3), and lead (Pb). These pollutants are measured and aggregated to provide an overall air quality rating, which is then categorized into six levels: Good, Satisfactory, Moderately polluted, Poor, Very Poor, and Severe

Analysis of the Dam Safety Act (2021) in India
GS3/GS1 Paper
Syllabus: Environment/Geography/ Disaster Management
Source: TH
Context: The Dam Safety Act in India, passed in late 2021, aims to address issues related to the safety of dams, given that many of them are old and pose safety risks. However, a recent disaster in Sikkim highlights gaps in implementation.
Also read an article on a similar theme published a few days ago: Dangers of Large Dams in India
India is the 3rd largest dam-owning nation in the world. There are around 5,700 large dams in the country, of which about 80% are over 25 years old.
Threats faced by Dams in India:
| Threats | Description |
| Ageing | Over 80% of India’s 6,000+ dams are over 25 years old, and more than 200 are over a century old, making safety a top concern. By 2025, over 1,000 dams will be 50 years or older. |
| Accumulation of Sediments & Siltation | The buildup of sediments in reservoirs reduces their capacity and lifespan. Siltation, the accumulation of silt and debris behind dams, also reduces storage capacity. |
| Structural Issues | Many of India’s dams are earthen, constructed from layers of compacted earth, making them susceptible to ageing and deterioration. |
| Flooding | India’s concentrated annual rainfall patterns, as opposed to distributed rainfall, increase the vulnerability of dams. Flooding has been responsible for 44% of dam failures in India. |
| Seismic Threat | Dam systems in the Himalayas, like the Tehri Dam, face seismic risks due to the region’s active tectonic movements and changing terrain |
Issues with the implementation of the Dam Safety Act (DSA), 2021:
| Issues | Description |
| Lacunae in Legislation | The DSA does not promote risk-based decision-making and fails to incentivise transparency |
| Jurisdiction Question | The Act applies to all specified dams in the country, but there’s a question of whether Parliament has the jurisdiction to regulate dams on rivers entirely within a state. |
| Standardized Safety Evaluation Issue | The DSA mandates comprehensive dam safety evaluations but lacks standardization in how failures are analyzed and reported. |
| Transparency and Accessibility | The Act does not sufficiently provide easy access to information for various stakeholders |
| Government employees and project engineers dominate decision-making | |
| Absence of early warning systems | During the glacial lake outburst flood (GLOF) in North Sikkim’s South Lhonak Lake (Oct 2023), there was the absence of early warning systems and preventive measures as required by the Act. |
| Pattern of Neglect | Frequent and large-scale dam-related disasters indicate a pattern of neglect in addressing dam safety. |
| Poor compliance at all levels, including dam design and spillway capacity, is highlighted by the Sikkim incident. |
Way forward:
- Risk Assessment: Comprehensive risk assessments, including climate change and geological stability, are essential. Regular reviews update safety measures.
- Hazard Profiling: Hazard risks are influenced by climate change and urbanization, but reviews are often overlooked or not shared publicly.
- Transparency: Transparency in dam safety, with rigorous implementation and transparent reporting, is paramount.
- Community Involvement: Engaging local communities for insights into environmental and social impacts.
- Early Warnings: Advanced early warning systems are crucial for detecting hazards and minimizing damage.
- Maintenance: Regular maintenance and upgrades for ageing infrastructure are necessary.
- International Collaboration: Cooperation with neighbouring countries in the Himalayan region is vital for addressing shared risks in dam safety and disaster management.

Context: China has implemented export restrictions on certain graphite products, citing national security concerns, as part of its broader efforts to control critical mineral exports.
- China is the world’s largest producer of natural graphite, accounting for two-thirds of global supply.
- While Mozambique, Madagascar, and Brazil are significant non-Chinese producers, China also refines over 90% of the world’s graphite for use in EV battery anodes
About Graphite:
Graphite is a naturally occurring crystalline form of carbon. It’s made up of stacked layers of graphene. Graphite is the most stable form of carbon under standard conditions.
Graphite is a mineral that’s found in metamorphic and igneous rocks. It’s extremely soft, cleaves with very light pressure, and has a very low specific gravity.
Graphite is a good conductor of electricity and heat. It’s also lighter than diamond, smooth and slippery to touch.
Graphite, a key component in electric vehicle (EV) batteries, has seen a surge in demand due to the growth of the EV industry. The battery end-use market for graphite has grown by 250% globally since 2018
Manual scavenging
Facts for Prelims (FFP)
Source: Deccan Herald
Context: The Supreme Court of India has expressed distress over deaths occurring during sewer cleaning due to the practice of manual scavenging and issued a directive to government authorities.
- Over the past five years, 347 people have lost their lives while cleaning sewers and septic tanks in India.
Directives:
- Required to provide compensation of Rs 30 lakh to the families of individuals who lose their lives while cleaning sewers.
- The court also stated that those who suffer permanent disabilities during such work should receive a minimum compensation of Rs 20 lakh, while those with other disabilities caused by sewer cleaning should receive Rs 10 lakh.
- The court emphasized the need to completely eradicate manual scavenging and noted that the Union and state governments have a duty to ensure this practice is eliminated.
Manual scavenging is the practice of manually cleaning, handling, and disposing of human excreta and other waste materials from dry latrines, open drains, and sewers. It has been officially banned in India since 1993

Context: The Ministry of External Affairs (MEA) in India has responded to Canada’s claims regarding India’s call for diplomatic parity, urging that its actions are in accordance with Article 11.1 of the Vienna Convention on Diplomatic Relations and do not violate international norms.
About Vienna Convention:
The Vienna Convention on Diplomatic Relations is a United Nations treaty that defines the rules and regulations of diplomatic relations between countries. The treaty was adopted in 1961 by the United Nations Conference on Diplomatic Intercourse and Immunities in Vienna, Austria.
- The treaty sets common principles and terms on how countries must treat each other’s diplomatic representatives.It also defines the privileges that diplomats enjoy in other countries.
The treaty provides a framework for:
- Establishing, maintaining, and terminating diplomatic relations
- Ensuring friendly relations
- Maintaining proper communication channels between countries
Visa Shopping
Facts for Prelims (FFP)
Source: IE
Context: The practice of ‘visa shopping’ has been gaining popularity in several Indian states.
- “Visa shopping” is a practice where individuals obtain visas for countries, they may not visit during the visa’s validity period.
Reasons for Visa Shopping:
- The objective is to use these visas as a means to enter their preferred countries, particularly in Europe, even if they already have a visa for another European nation.
- People also buy visas for countries they don’t intend to visit immediately to increase their chances of getting visas for their preferred destinations in the future. This practice is prevalent in India, particularly in Punjab, and it has raised legal implications.
Example:
- One of the examples of visa shopping is the “Schengen Visa,” which allows travellers to explore multiple European countries without requiring separate visas.
- Under the Schengen system, an agreement among European countries, travellers can move freely within the Schengen Area without border controls. This allows entry into 27 countries, including 23 EU members and some others.
Legal issues can arise if a traveller obtains a visa for one country but stays in another or uses it as an entry point rather than their actual destination.
SIM cards
Facts for Prelims (FFP)
Source: TH
Context: The growing use of mobile phones have highlighted the importance of SIM cards, or Subscriber Identification Module cards, which are essential components for connecting mobile phones to cellular networks following the GSM standard.
- The SIM card contains information, such as the International Mobile Subscriber Identity (IMSI), the subscriber’s location, a list of preferred networks for roaming, emergency numbers, and, space permitting, the subscriber’s contacts and SMS messages.
- SIM cards adhere to international standards (ISO/IEC 7816) maintained by organizations like the International Organization for Standardization.
Functioning:
The SIM card hardware features an integrated circuit connected to metal contacts on the card’s surface. These contacts serve specific purposes, like power supply, clock access, data transmission, and grounding, as defined by ISO/IEC 7816-2. The SIM card plays a crucial role in authenticating a phone’s place within a cellular network.
Evolution of SIM cards:
SIM cards have evolved in size, from full-size SIMs to nano SIMs. The latest development is the eSIM (eUICC), where the SIM software is preloaded onto the mobile equipment, eliminating the need for a physical card.
This reprogrammable eSIM is environmentally friendly and enhances security, as it is not physically removable, making it harder for malicious individuals to access the SIM application. However, it can potentially allow network operators to track users’ data more comprehensively, even within apps on the device.
Ghost particle
Facts for Prelims (FFP)
Source: Frontline
Context: China is constructing the world’s largest “ghost particle” detector, a massive underwater telescope in the South China Sea, designed to detect neutrinos, which are often referred to as “ghost particles.”
- The telescope, named “Trident,” is expected to span 7.5 cubic kilometers and be 10,000 times more sensitive than existing underwater telescopes.
- It is being built in the South China Sea to detect neutrinos, which can interact with water molecules.
The significance of detecting neutrinos lies in their mysterious behaviour and their potential role in solving scientific mysteries.
Neutrinos are subatomic particles that have very little mass and no charge, and they interact very weakly with other particles, making them challenging to detect
