From UPSC perspective, the following things are important :
Prelims level: TCAS-Kavach ATP System, RFID
Mains level: NA

The Supreme Court has acknowledged and appreciated the implementation of the indigenous anti-collision system KAVACH.
What is KAVACH?
- Kavach, an automatic train protection (ATP) system, was initially named Train Collision Avoidance System (TCAS).
-
- Development commenced in 2011 as Indian Railways and Research Designs & Standards Organisation (RDSO) sought a domestically developed ATP system.
- B. Rajaram, credited with developing the Skybus Metro system, played a key role in Kavach’s development.
- Field trials began in 2014, refining the system’s specification.
- Final approval was granted in 2019, certifying Kavach for compliance with Safety Integrity level 4 (SIL-4) operations.
Working Mechanism:
- Kavach comprises trackside Radio Frequency Identification (RFID) tags, onboard locomotive equipment, and radio infrastructure.
- It communicates via radio, enabling real-time train monitoring.
- Drivers receive alerts, and automatic braking is triggered to prevent collisions.
- Kavach uses various data inputs like location, direction, and time to ensure safety.
- Event recorders retain records of interactions and incidents for analysis.
- Alerts and automatic braking ensure an immediate response to hazardous situations.
How does it help prevent collision?
- Kavach is designed to alert the locomotive pilot if they fail to notice a ‘red signal’ and continue at a speed that would surpass the signal.
- If the pilot does not slow down below 15 kmph, Kavach automatically applies the brakes, bringing the train to a halt.
Issues with KAVACH
- High Deployment Cost: Implementing Kavach costs ₹50 lakh per kilometer for the Indian Railways.
- Low Coverage: Currently, Kavach covers only 1,500 kilometers of rail routes, a small fraction of the total 68,000-kilometer network (as of November 2023).
- Expanding its coverage, particularly on high-density routes, remains a formidable challenge.

From UPSC perspective, the following things are important :
Prelims level: International Banking Institutions; Types of Inflation;
Mains level: NA
Why in the News?
The Asian Development Bank recently issued a cautionary note for India’s susceptibility to imported inflation due to potential rupee depreciation amidst escalating interest rates in the West.
What is Imported Inflation?
- Imported inflation refers to the increase in the prices of goods and services within a country caused by a rise in the cost or price of imports.
- This phenomenon occurs when factors such as a depreciating currency, higher import costs, or increased international prices lead to elevated expenses for imported goods and services.
- Consequently, producers may adjust their prices upward to offset these higher costs, resulting in inflationary pressures within the domestic economy.
- This idea connects with the theory of cost-push inflation, which means that when input costs go up, it can cause prices for final products to go up too.
Reason behind the imported inflation:
- Capital Flows: Increased interest rates in Western economies attract foreign investors seeking higher returns, leading to capital outflows from countries like India and potentially depreciating the Indian rupee.
- When a currency depreciates, local consumers require more of their domestic currency to procure foreign goods, consequently elevating import prices.
- Borrowing Costs: Indian businesses and the government may face higher borrowing costs for infrastructure projects and investments if they raise funds in foreign currency-denominated international markets.
- Inflationary Pressures: Capital outflows can pressure the Indian rupee, causing imported inflation as the cost of imported goods rises due to currency depreciation.
- Trade Competitiveness: Exchange rate fluctuations from Western interest rate changes affect India’s trade competitiveness, impacting exports, imports, and domestic consumption.

Prelims level: Easement Rights, Indian Easements Act, 1882
Mains level: NA
Why in the news?
- The Supreme Court observed that a claimant of an Easementary Right cannot claim an Easement by necessity if there exists an alternative way to access the property owned by the claimant, known as the ‘Dominant Heritage‘.
- The court referred to Section 13 of the Indian Easements Act, of 1882, which deals with easementary rights by necessity.
What is Easement Right?
- An Easement is a legal right to use someone else’s property for a specific purpose without possessing it.
- Essentially, it’s a permission or privilege granted by the owner of one property (the servient land) to someone else (the dominant land) to use the servient land in a particular way.
Legal backing for Easement Rights
- Section 13 of the Indian Easements Act, 1882, serves as the cornerstone in adjudicating easementary rights disputes.
- It mandates that such rights can only be claimed if no alternative access to the Dominant Heritage exists, providing clarity in legal proceedings.
- Understanding terms like ‘Dominant Heritage’ (represents the property for enjoyment) and ‘Servient Heritage‘ (property over which rights are sought) is crucial in comprehending easementary rights disputes.
Features of the Indian Easements Act, 1882:
- Definition of Easements: The law defines what an easement is and the different types, like rights of way (to pass through someone’s land), rights to light and air, and rights to use water.
- Acquisition of Easements: It explains how easements can be created. For example, by agreement between the parties or through long-time use.
- Rights and Liabilities: It outlines the rights and responsibilities of both the person who has the easement (the beneficiary) and the person who owns the land over which the easement exists (the servient owner). For instance, the beneficiary must not do anything to increase the burden of the easement, and the servient owner must not obstruct the use of the easement.
- Termination of Easements: It describes the circumstances under which an easement can come to an end. For example, if the purpose for which the easement was created ceases to exist, or if the beneficiary expressly gives up their right.
- Customary Easements: It recognizes certain easements that arise due to local customs or traditions.

From UPSC perspective, the following things are important :
Prelims level: Mahad (Chavdar Lake) Satyagraha, Annihilation of Caste etc.
Mains level: NA

Why in the news?
The Mahad Satyagraha is hailed as the foundational event of the Dalit movement, marking the community’s collective rejection of the caste system and assertion of human rights.
About Mahad Satyagraha
- The Mahad Satyagraha, also known as Chavdar Tale (Lake) Satyagraha, was led by B. R. Ambedkar on 20 March 1927 in Mahad, Raigad District of Maharashtra.
- Its aim was to assert the right of untouchables to use water from a public tank.
- Background:
- Untouchables (Dalits) were segregated in Indian society and banned from using public water bodies and roads used by other Hindu castes.
- In August 1923, the Bombay Legislative Council passed a resolution allowing depressed classes to use government-maintained places, but it faced opposition from savarna Hindus.
- In January 1924, Mahad passed a resolution in its municipal council to enforce the act but failed to implement it due to protests.
- Satyagraha:
- In 1927, Ambedkar launched a satyagraha to assert untouchables’ rights to use water in public places.
- Mahad was chosen for the event due to its support from ‘caste Hindus’.
- Surendranath Tipnis, president of the Mahad municipality, invited Ambedkar to hold a meeting there.
- Ambedkar drank water from the tank, followed by thousands of untouchables.
- He encouraged Dalit women to abandon customs of untouchability and wear saris like high-caste women, which they embraced.
- A riot erupted over rumors of Ambedkar planning to enter a Hindu temple, and the tank was purified with cow-urine and cow-dung.
- Ambedkar planned a second conference in Mahad in December 1927 but faced legal obstacles due to a case filed by caste Hindus.
- On 25 December 1937, the Bombay High Court ruled that untouchables have the right to use water from the tank.
- Legacy:
- On 19 March 1940, Ambedkar arranged a rally in Mahad to commemorate the Satyagraha as “Empowerment Day.”

Prelims level: Science Based Targets Initiative (SBTi)
Mains level: NA
Why in the news?
- The recent gathering of major funders and promoters of the carbon offsets market in London raised concerns about the role of the Science Based Targets initiative (SBTi) in limiting the market’s growth.
- SBTi’s stringent criteria for net-zero plans have made it a gold standard in emissions accountability, but some argue it hinders the potential of carbon offsets in combating climate change.
What is Carbon Offset?
- A carbon offset broadly refers to a reduction in GHG emissions – or an increase in carbon storage (e.g., through land restoration or the planting of trees) – that is used to compensate for emissions that occur elsewhere.
- A carbon offset credit is a transferrable instrument certified by governments or independent certification bodies to represent an emission reduction of one metric tonne of CO2, or an equivalent amount of other GHGs.
|
What is Science Based Targets Initiative (SBTi)?
- The SBTi is a collaborative effort spearheaded by four international organizations:
- Carbon Disclosure Project (CDP),
- United Nations Global Compact (UNGC),
- World Resources Institute (WRI), and
- World Wide Fund for Nature (WWF).
- The SBTi focuses on assisting companies in setting ambitious and scientifically sound greenhouse gas (GHG) emission reduction targets.

Prelims level: Jallianwala Bagh Massacre, Rowlatt Act, Hunter Commission
Mains level: NA

Why in the news?
On April 13, 1919, Brigadier-General Reginald Dyer ordered British troops to open fire on a peaceful gathering in Jallianwala Bagh, Amritsar, leaving a deep scar on India’s collective memory.
Jallianwala Bagh Massacre
- Background: Protesting the contentious Rowlatt Act
- The act officially known as the Anarchical and Revolutionary Crimes Act, 1919 was passed in 1919 by the Imperial Legislative Council.
- It had authorized the British government to arrest anybody suspected of terrorist activities.
- It also authorized the government to detain such people arrested for up to 2 years without trial.
- It empowered the police to search a place without a warrant. It also placed severe restrictions on the freedom of the press.
- The primary intention of colonial govt. was to repress the growing nationalist movement in the country.
- The British were also afraid of a Ghadarite Revolution in Punjab and the rest of the country.
- The day
- The massacre took place on 13 April 1919 when troops of the British Indian Army (Gurkha and Sikh infantry regiments) under the command of Col. Reginald Dyer fired rifles into a crowd of Indians.
- The civilians had assembled for a peaceful protest to condemn the arrest and deportation of two national leaders, Satya Pal and Saifuddin Kitchlew.
- Dyer without warning ordered his troops to fire at the unarmed crowd which included children as well.
- The indiscriminate firing went on for about 10 minutes which resulted in the deaths of at least 1000 people and injured more than 1500 people.
- Aftermath
- In protest against the massacre, Rabindranath Tagore gave up his knighthood.
- Gandhiji relinquished his title ‘Kaiser-e-hind’ bestowed on him by the British for his services during the Boer War in South Africa.
- Michael O’Dwyer, the then Lieutenant-Governor of Punjab, who had approved the actions of Dyer, was assassinated by Udham Singh in London in 1940 as revenge against the massacre.
- The heroic treatment of Dyer’s heinous act again set a benchmark of colonial arrogance.
Hunter Commission for Inquiry
- In October 1919 the Secretary of State for India, Edwin Montagu, ordered the formation of a committee of inquiry into the events in Punjab.
- Referred to as the Disorders Inquiry Committee, it was later more widely known as the Hunter Commission (Not to be confused with Hunter Education Commission).
- The commission inquiry was concluded without any significant conclusion.
- Still, there are long-standing demands in India that Britain should apologize for the massacre.

Prelims level: Indian Ocean Observing System (IndOOS)
Mains level: NA

Why in the news?
India and the US have decided to reactivate the Indian Ocean Observing System (IndOOS).
What is IndOOS?
- Established in 2006, the Indian Ocean Observing System (IndOOS) comprises moored buoys strategically placed across the Indian Ocean.
- It consists of a network of 36 moored buoys in the high seas to collect high-resolution ocean and atmospheric data for weather forecasts.
- These buoys measure various parameters like seawater temperature, salinity, ocean currents, atmospheric humidity, and wind speed.
- IndOOS originally focused on understanding and predicting the monsoon.
- It now aids in climate modelling under changing climatic conditions and predicts extreme weather events such as floods, droughts, and cyclones.
Objectives of IndOOS include:
- The primary objective of IndOOS is to provide continuous and high-quality oceanographic and meteorological data to support informed decision-making and improve scientific understanding of weather and climate.
- It aims to foster partnerships among Indian Ocean countries and beyond to enhance long-term monitoring and forecasting capabilities.
Need for IndOOS
- The Indian Ocean region, home to nearly one-third of the global population, faces significant vulnerabilities due to climate change and extreme weather events.
- Fisheries and rain-dependent agriculture in these regions are heavily influenced by the monsoon, making accurate weather forecasts crucial for mitigating potential damage to crops and livelihoods.
- The Indian Ocean’s influence extends beyond its boundaries, redistributing heat across the planet and modulating the climate in the Pacific, North Atlantic and Mediterranean Sea.
Observing Networks under IndOOS
- The framework for IndOOS comprises five observing networks:
- Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA)
- Profiling floats (part of the global Argo array)
- Surface drifters (Global Drifter Program, GDP)
- Repeat temperature lines (eXpendable Bathy Thermograph (XBT) network)
- Tide gauges
- These networks are complemented by satellite observations of surface wind, sea level, temperature, salinity, rainfall, and ocean color.
Partnerships and Support:
- IndOOS originated from discussions among scientists during the First International Conference on the Ocean Observing System for Climate (OceanObs) in 1999.
- An implementation plan for IndOOS was developed by the Indian Ocean Panel, established under the Climate and Ocean Variability, Predictability, and Change (CLIVAR) and Intergovernmental Oceanographic Commission – Global Ocean Observing System (IOC-GOOS) programs.

From UPSC perspective, the following things are important :
Prelims level: Obiter Dicta Lexicon, Misleading Advertisements
Mains level: NA

Why in the news?
- The Supreme Court ruling refusing to accept Patanjali’s MD’s unconditional apologies underscores the gravity of intentionally misleading advertisements and their repercussions.
- Despite apologies, Patanjali’s breach of its commitment not to disseminate false claims about curing various illnesses led to this decision.

The Concept of Obiter Dicta Lexicon:
- In the context of the criticism directed towards the Hon’ble Supreme Court Bench’s statement in the Patanjali case, the concept of “obiter dicta lexicon” may find relevance.
- “Obiter dicta” is a Latin term that translates to “things said by the way” and refers to statements made by a judge in passing, which are not essential to the decision of the case at hand.
- It refers to the use of language or expressions that are not directly relevant to the legal reasoning or decision-making process in a court judgment or opinion.
SC Bench Statement on Patanjali’s Apology:
- The statement “we will rip you apart” is being criticized for being overly aggressive and potentially inappropriate for a judicial setting.
- Therefore, in this case, the use of language that deviated from the core legal issues at hand and instead conveyed a sense of aggression or hostility could be viewed as part of the “obiter dicta lexicon.”
|
Understanding Misleading Advertisements:
