Context (TH | IE): Israel, through the ‘Ben Gurion Canal,’ aims to eliminate Hamas in Gaza.
Ben Gurion Canal is a proposed waterway through the Negev Desert in Israel, intended to create an alternative to the Suez Canal.
Significance
It aims to challenge Egypt’s monopoly on the shortest route between Europe and Asia.
Through the canal, Israel aims to eliminate (Hamas in) Gaza to ensure economic opportunities, peace, and political stability (in Israel alone) in the region (Palestine-less Isreal)!
Challenges
The planned route is over 100 km longer than the Suez Canal.
The canal’s military focus could potentially hamper trade in the region.
Context (TH |PIB): The GoI is providing food grains free of cost to the Antyodaya Anna Yojana households and Priority Households beneficiaries under the Pradhan Mantri Garib Kalyan Anna Yojana (PMGKAY).
The decision has been taken to strengthen the provisions of the National Food Security Act, 2013.
PMGKAY is operated by the Ministry of Consumer Affairs, Food and Public Distribution.
Objective: To feed the poorest citizens of India by providing free grain through the Public Distribution System to all eligible households under the National Food Security Act (NFSA) 2013.
PMGKAY will subsume the two subsidy schemes of the Department of Food & Public Distribution:
Food Subsidy to Food Corporation of India (FCI) – For centralised procurement by FCI.
Food Subsidy for decentralized procurement by states.
Eligible households:Primary Households (PHH) and Antodaya Anna Yojana (AAY) households under NFSA, 2013.
Provision under NFSA
Free Foodgrain: Rice, wheat, and coarse grains for a period of one year (Jan 2023 – Dec 2023).
Quantity: 35 kg per Antyoday Anna Yojana Household and 5kg per person to a Priority Household (as under NFSA, 2013).
PMGKY Vs. NFSA, 2013
Under NFSA, 2013, beneficiaries pay subsidised prices called Central Issue Price (CIP) worth Rs.1, Rs.2, and Rs.3 for coarse grains, wheat, and rice, respectively.
Under PMGKY foodgrains are provided free of cost.
Merger of PM-GKAY and NFSA
In 2022, PMGKAY was merged with NFSA and extended until December 2023.
Under this merger, the entire food grains under PM-GKAY and NFSA were made free of cost.
National Food Security Act, 2013
Coverage and entitlement under Targeted Public Distribution System (TPDS)
It covers 50% of the urban population and 75% of the rural population.
Uniform entitlement of 5 kg per person per month.
Food at subsidised prices: Rs. 3/2/1 per kg for rice, wheat, and coarse grains.
However, the poorest of the poor households will continue to receive 35 kg per household per month under Antyodaya Anna Yojana (AAY).
Identification of Households to be done by States/UTs under TDPS determined for each State.
For the purpose of issuing ration cards, the eldest woman of the household of age 18 years or above is to be the head of the household.
The Act provides for food security allowance in case of non-supply of entitled foodgrains or meals.
Coverage
The free nutritious meal to pregnant women and lactating mothers and children up to 6 years of age under the Integrated Child Development Services (ICDS) scheme.
The free nutritious meal to children in the 6-14 age group under the Mid-Day Meal Scheme.
Pregnant women and lactating mothers will receive a maternity benefit of Rs. 6,000.
Context (TH): A report published by the Parliamentary Standing Committee held that the BNSS Bill introduces safeguards to prevent the registration of cases against Armed Forces personnel for acts performed in the ‘line of duty’ without the prior consent of the Union/State govt.
The proposed provision will be in addition to the Armed Forces Special Powers Act (AFSPA) that gives unbridled power to the armed powers deployed in ‘disturbed areas.’
The CrPC protects the armed forces only from arrest, and there are no conditions regarding the registration of criminal cases.
{GS2 – MoLE – Schemes} Employee State Insurance (ESI) Scheme
Context (PIB): The recent provisional payroll data of the Employee State Insurance (ESI) scheme revealed that 18.88 lakh new employees were added in the month of September.
The ESIschemeis a self-financed integrated measure of Social Insurance embodied in the Employee State Insurance Act.
The scheme is administered by the Employee State Insurance Corporation (ESIC), an autonomous corporation under the Ministry of Labour and Employment (MoLE).
Coverage
The ESI scheme is designed for non-seasonal factories (factories and other establishments like Hospitals, Roads, Cinemas, etc) employing 10 or more persons.
However, the threshold limit for coverage of establishments is still 20 employees in some states.
Eligibility

{GS2 – MoTA – Schemes} PM-PVTGs Development Mission
Context (PIB): PM launched the Pradhan Mantri Particularly Vulnerable Tribal Groups (PM-PVTGs) Development Mission.
PM-PVTGs aims to improve the socio-economic conditions of the particularly vulnerable tribal groups (PVTGs) by saturating PVTG families and habitations with basic facilities such as:
Safe housing
Clean drinking water and sanitation
Improved access to education
Health and nutrition
Road and telecom connectivity
Sustainable livelihood opportunities
Under the scheme, several ministries will collaborate to implement development projects. The schemes include Pradhan Mantri Gram Sadak Yojana, Pradhan Mantri Gramin Awas Yojana, and Jal Jeevan Mission, among others.
The Ministry of Tribal Affairs (MoTA) is the Nodal Ministry for overall policy planning and coordination of programs for the development of STs.
Particularly Vulnerable Tribal Groups (PVTGs)
PVTGs are a more vulnerable group among tribal groups in India.
These groups have primitive traits, geographical isolation, low literacy, zero to negative population growth rate and backwardness.
They largely depend upon hunting and a pre-agriculture level of technology.
In 1973, the Dhebar Commission set up a separate category for Primitive Tribal Groups (PTGs).
In 1975, the Centre identified 52 tribal groups as PTGs. In 1993, 23 more groups were added to the list.
In 2006, these groups were named Particularly Vulnerable Tribal Groups (PVTGs).
Population of PVTGs
Currently, 2.8 million PVTGs belong to 75 tribes across 18 states and UTs in India.
According to the 2011 Census, Odisha has the largest population of PVTGs, followed by Madhya Pradesh and Andhra Pradesh (including Telangana).
The largest PVTG is Odisha’s Saura community, numbering 535,000.

{GS2 – Polity – IC – FRs} Right to Privacy: Seizure of Digital Devices
Context (TH): The SC expressed concern over the arbitrary seizure of digital devices and asked the Centre to frame guidelines to govern such actions by agencies.
The legal Position
Journalists do not have any legal protection against the seizure of their digital devices.
Under Sec 165 of CrPC, if there are reasonable grounds, the police can search devices during a probe.
Section 102 of CrPC gives police the power to seize any property that may be found under circumstances that create suspicion of the commission of the offense.
The IT Act of 2000 mandates the creation of a hash value for electronic evidence before forensic analysis, ensuring its integrity.
The hash value is unique, much like a fingerprint. It changes if a document or file is planted on the device, allowing the owner to determine if it has been tampered with.
SC’s Position
The SC, in many cases, upheld the importance of a journalist’s device.
In 2022, a Delhi court held that an investigating agency hasno right to seek the passwordof the electronic device of an accused without their consent.
In July 2023, the Kerala HC said that the policecannot seize a journalist’s phone in connection with a case without following the due procedure.
In November 2023, the SC asked the Centre to frame guidelines to govern the seizure of individuals’ devices, particularly media professionals.
Issues
Tampering: In many seizures, journalists were not provided with hash values. Officers can plant files on a device without the owner’s knowledge.
Confidentiality at Risk: It’s possible that seized devices could be used to identify journalists’ sources.
Affects the personal life: Officers often ask journalists to provide passwords to their work and personal accounts.
Affects professional life: Many journalists record shows or write articles on their phones.
Press Freedom Infringement: Actions against journalists infringe on the freedom of the press.
The right to privacy is a fundamental right.
Way Forward
The press is considered the fourth pillar of democracy, and if it can’t function independently, it will harm the foundations of our democracy.
Excessive government powers without proper guidelines would be dangerous. Therefore, GoI must formulate guidelines to govern the seizure of devices, with an emphasis on safeguarding privacy.
The guidelines must include the following key elements:
Judicial Warrants: Law enforcement agencies should be permitted to seize or search devices without a prior judicial warrant specifying the information sought.
Protection: Journalists should not be compelled to provide passcodes/biometric data.
Data Safeguards: Ensure the security of devices and data, preventing leaks, tampering, or unauthorized sharing.
{GS2 – Polity – IC – Reservation} Sub-categorisation of SCs
Context (TH): PM announced the formation of a committee to consider sub-categorization of the Madiga community within the Scheduled Castes (SC) in Telangana.
TheChinnaiah casedid not allow governments to introduce sub-quotas for the more backward SCs and STs.
In the Chinnaiah case (2005), the SC said that:
The governments cannot introduce a sub-quota within the SC and ST quota in favour of a few castes or tribes more backward than others on the list.
The SC said that the object of Article 341 of IC was to eliminate political factors in the identification of SCs, and the government had no power to “disturb” the presidential list.
It was held that the SCs and STs specified in their respective lists form a class by themselves, and regrouping or reclassifying themviolates the Constitution.
The state governmentdoes not have the power to sub-classify SCs.
Under Article 341 of IC, the President notifies a list of SCs for each state, which can thereafter only be modified by Parliament and not the state legislature.
Since the state government could not add or remove a caste from the list, it could not allot separate sub-quotas to various castes in the list either.
In Davinder Singh’s case (2020), the SC disagreed with the Chinnaiah case verdict and referred the issue to a larger bench for reconsideration.
In Davinder Singh’s case (2020), Justice Mishra said, “In a federal structure, the state government cannot be denied the power to make laws to give preferential treatment to sub-categories within the reservation list.“
Commission for sub-categorisation of SCs
A national commission was constituted by GoI to examine the issue of sub-categorisation of SCs in Andhra Pradesh.
The commission submitted its report in May 2008 recommending amendment of Article 341 of the Constitution to provide for sub-categorisation of SCs.
States’ opposition to the sub-categorisation
In 2020, fourteen states have opposed the Centre’s proposal to sub-categorise SCs and only seven have supported the move.
Backwardness Data
In Nagaraj and Jarnail Singh, a Constitution Bench of the SC held that before the government introduces any reservations for communities other than SCs and STs, it must collect quantifiable data that show that those communities are backward.
No such data collection exercise is necessary for SCs and STs who are presumed to be backward once they are included within the lists under Articles 341 and 342 of the Constitution.
Way Forward
Treating the entire list of SCs in a state as a homogenous category and presuming that each caste within the list was as backwards as the other SCs is not correct.
There are several castes included within the presidential list of SCs in a state, but some of them may be ahead of others.
Hence, sub-classification within the SC community:
Ensures equal distribution of benefits to every community.
Prevents the dominant community from monopolizing them.
Sub-classification of OBCs
In M.R. Balaji v. State of Mysore (1963), the Constitution Bench of SC held that this sub-classification of OBCs into backward and more backward was impermissible. The court said that Article 15(4) of IC only allows reservation for the really backward classes.
The SC in Indra Sawhney v. Union of India case (1992) held that sub-classification was permissible among OBCs.
{GS2 – Vulnerable Sections – STs} Community Rights and Forest Conservation
Community rights refer to a community or group’s collective rights and interests.
They recognize the rights of communities to:
self-determination
self-governance
control over their own resources and development
They are based on the understanding that communities are more than just groups of individuals; they are distinct entities with unique identities, cultures, and interests.
Importance of Community Rights
Self-determination and empowerment
Protection from exploitation and marginalization
Sustainable resource management
Preservation of cultural heritage
Promotes social justice
Environmental protection
Conflict resolution and peacebuilding
Reduction in man-animal conflict
How FCA 2023 Undermines Community Rights?
Exempting Forest Lands from the Purview of the Act
The Act adds more activities that are excluded from the restriction on dereservation, such as:
zoos and safaris under the Wild Life (Protection) Act, 1972,owned by the government or any authority,in forest areas other than protected areas
eco-tourism facilities
silvicultural operations(enhancing forest growth)
any other purpose specified by the GoI
The Act will now apply exclusively to areas categorized under the Indian Forest Act of 1927 and those designated as such on or after October 25, 1980.
The Act exempts certain types of land from the provisions of forest law. They include:
Forest land along government-maintained rail lines or public roads, providing access to habitation or rail, with roadside amenities, up to a maximum size of 0.10 hectares.
Forest land within 100 km along international borders, LOC, or LAC, intended for strategic projects of national importance or security construction
Forest land up to 10 hectares earmarked for security-related infrastructure construction
Forest land designated for defense projects, paramilitary force camps, or specified public utility projects by the GoI (limited to 5 hectares in left-wing extremism-affected areas)
Forest land converted to non-forest use on or before December 12, 1996
Removal of the Requirement of Prior Consent from Gram Sabha
The FCA underwent crucial amendments in 2016 and 2017, which made prior consent from tribal gram sabhas mandatory for any forest alterations for non-forest purposes.
However, FCA 2023 have removed the necessity for such consent.
In this context, State governments can engage gram sabhas in land acquisition for various purposes through State-level steering committees within the existing framework.
But many state governments may hesitate, perceiving Adivasi gram sabhas as anti-development and impeding economically beneficial afforestation initiatives.
Flawed Compensatory Afforestation
FCA 2023 makes the land transfer for compensatory afforestation easy.
But it does not specify the trees that should be planted.
Generally, monoculture is practiced in compensatory afforestation, which leads to biodiversity loss.
Moreover, it will not serve the communities who have suffered from the cutting down of the forest.
Tt aims to integrate conservation and livelihood rights of the people.
Despite initial enthusiasm, Central and State governments seem less inclined to implement the FRA in their respective states.
Reasons for lack of enthusiasm:
Many see the Act as a barrier to converting forest land for non-forest purposes.
The state government and its bureaucracy believe that granting community rights under the FRA could weaken the state’s authority over the forest.
Now, the dilution of FCA, rather than amending the FRA, further limits claims of Adivasi rights.
Way Ahead
FCA should be amended in a way where the conservation of forests/biodiversity and community rights of indigenous people should be the priority.
Economic gains from forests can be pursued without compromising biodiversity and community rights.
Synchronicity between FCA and FRA should be developed to preserve community rights.
{GS3 – IE – Inflation} Indian Rupee Depreciation
Context (IE | LM | IE): Rupee depreciation negatively impacted petroleum product imports, but its positively impacted petroleum product exports from India.
Rupee depreciation is the decline in the value of the Indian rupee against other foreign currencies, particularly the US dollar. This means that it takes more rupees to buy one dollar.
Rupee depreciation can have a significant impact on the Indian economy, both positive and negative.
Reasons of Rupee Depreciation
Trade Imbalance:Increased demand for foreign currencies for imports can pressure the domestic currency, leading to depreciation.
Inflation Differentials:Higher inflation than trading partners erodes a country’s currency purchasing power.
Interest Rates:Lowering interest rates by a country’s central bank can make its currency less attractive to investors seeking higher returns, leading to depreciation.
Speculation: If traders and investors anticipate that a currency will weaken in the future, they may sell it in large volumes, causing its value to decline.
Political and Economic Stability: Political instability, economic uncertainty, or financial crises can undermine investor confidence, leading to currency depreciation in a country.
External Debt: As external debt needs to be serviced and repaid in foreign currencies, the demand for those currencies increases, leading to depreciation of the domestic currency.
Global Economic Conditions: Factors such as global economic slowdowns, financial crises, or geopolitical tensions can impact currency values.
Impacts of Rupee Depreciation
Positive Impacts of Rupee Depreciation
Export competitiveness: A weaker rupee makes Indian goods and services more competitively priced in international markets.
Boosts tourism: Cheaper travel expenses due to a weaker rupee can boost tourism revenue.
Higher remittances: A weaker rupee increases the value of remittances.
Balance of Payments: Higher export earnings and reduced imports due to increased prices can improve the country’s balance of payments.
Negative Impacts of Rupee Depreciation
Increased debt burden: When the rupee depreciates, the cost of repaying these loans increases.
Inflation: The increased cost of imports combined with other factors contribute to inflation.
Trade deficit concerns: A weaker rupee may boost exports but raises concerns about a widening trade deficit if higher export earnings are offset by increased import costs.
Higher import costs
Reduced purchasing power
Volatility and uncertainty in financial markets
Why Indian Rupee is Depreciating in 2023
Capital outflows: Due to the high US dollar yields, investors are pulling out money from domestic markets and investing in the US market for higher returns.
The surge of US dollar was driven by investors seeking safe havens amidst concerns about:
a potential global recession
rising inflation in various countries
ongoing war in Ukraine
Inflation pressures: High inflation exerts a notable downward pressure on a country’s currency value.
India’s retail inflation, which is measured by consumer price index (CPI) surged to a 15-month high of 7.44% in July 2023, up from 4.81% in June.
Indian rupee was the worst performing Asian currency in 2022.
{GS3 – IE – Securities} Sahara Group Scam
Context (IE): Recently, the Sahara Group founder Subrata Roy died. Sahara Group faced multiple legal battles with his group firms accused of circumventing regulations with Ponzi schemes.
Subrata Roy
Subrata Roy was the founder of Sahara India Group. He expanded the group’s operations across various sectors, including finance, real estate, media, entertainment, tourism, healthcare, and hospitality.
His career was marked by legal issues, notably his involvement in the Sahara-SEBI case related to financial irregularities.
This led to his arrest in 2014 for failing to appear before the SC in a legal dispute with the Securities and Exchange Board of India (SEBI).
Sahara-SEBI Case
In 2008, two unlisted Sahara group companies, with paid-up capital of less than $20,000 each, raised funds from millions of small investors through Optionally Fully Convertible Debentures (OFCDs).
SEBI’s Ruling: In 2010, SEBI ruled that the fund-raising process of Sahara did not comply with the SEBI rules and ordered the group companies to refund the money to the investors, with 15% annual interest.
Sahara Group’s Stand: The group claimed that the money raised through “optionally convertible debentures” would not come under the SEBI jurisdiction as they are “privately placed.”
SEBI contended that a private placement should be fora maximum of fifty investors, not millions.
OFCDs can be converted into shares at the expiry of a certain period at a predetermined price if the debt holder (investor) wishes to do so. (OFCDs hedge the investor’s risk)
A private placementis a sale of stock shares or bonds to a pre-selected limited pool of investors (employeesand others within the close circle of promoters) rather than publicly on the open market.
Appeal against SEBI’s Ruling
The ruling of SEBI was challenged before the Securities Appellate Tribunal (SAT), which was upheld.
SC upheld the SAT ruling and ordered Sahara Group to deposit the money in 3 installments.
To facilitate the repayment, the Sahara-SEBI escrow account was established.
In 2013, SEBI issued orders to attach the group’s bank accounts and other properties after companies failed to pay the remaining two installments.
In March 2023, SC directed Rs. 5000 Crores to be transferred out of the “Sahara-SEBI Refund (Escrow) Account” to the Central Registrar of Cooperative Societies (CRCS).
Accordingly, the CRCS-Sahara Refund Portal has been developed by GoI to facilitate the refund process for crores of depositors who had invested money in the fraudulent Sahara Group’s firms.
Theescrow accountis a third-party accountthat acts as a secure place to hold the fundsbefore they are transferred to the ultimate party.
Central Registrar of Cooperative Societies (CRCS) is the statutory bodyresponsible for registration and other processes of the Multi-State Cooperative Societies (MSCS).
Citizenship of Subrata Roy’s Wife and Son
On account of multiple cases against Roy’s family, his wife and son gave up on Indian Citizenship.
They took the citizenship of Macedonia (a land-locked country in South-Eastern Europe).
To acquire the citizenship of Macedonia, a person must declare an investment of 4 lakh Euros and employ 10 local people to acquire Macedonian citizenship.

{GS3 – S&T – ISRO} NISAR Mission
Context (TH): Key tests, including the thermal vacuum testing, will be conducted before the launch of NASA-ISRO SAR (NISAR)in 2024.
NISAR is a Low Earth Orbit (LEO) observatory jointly developed by NASA and ISRO.
It will be launched onboard ISRO’s GSLV Mark-II launch vehicle.
It will map the entire globe in 12 days.
It will help understand changes in Earth’s ecosystems, ice mass, vegetation biomass, sea level rise, groundwater, and natural hazards (like earthquakes, tsunamis, volcanoes, and landslides).
It carries aSynthetic Aperture Radar (SAR), which operates with the Sweep SAR technique.
The SAR payloads mounted on the Integrated Radar Instrument Structure (IRIS) and the spacecraft bus are called an observatory.
LEO is an orbit around Earth with an altitude of 200 to 2,000 km above the Earth’s surface.
Thermal vacuum testing is a type of environmental testing that simulates space conditions to evaluate the performance of spacecraft and other hardware.
Synthetic Aperture Radar (SAR)
SAR uses radar antenna motion to generate a synthetic aperture, surpassing the size of the physical antenna.
It works by transmitting pulses ofmicrowave energy towards the Earth’s surface.
The energy reflected back to the radar is then analyzed to create an image of the surface.
Advantages of SAR
All-weather operation: Can operate in clouds and rain.
High-resolution imaging: Image resolution depends on the synthetic aperture size, dictated by the radar’s flight path length.
Day and night operation: It uses its own illumination source, not dependent on sunlight.
Long-range operation: Because microwaves can travel long distances through the atmosphere.
Wide range of applications: Used in environmental monitoring, military applications, agriculture, oceanography, and geology.
Penetration of vegetation and soil.
Ability to measure surface properties.
Sweep SAR
NISAR’s deployable antenna will operate in a unique mode called SweepSAR.
When it transmits microwaves, the radar’s signal feed is stationary, producing a narrow beam of microwave energy.
But when it receives the returning signal, the radar feed sweeps its beam across the antenna’s reflector.
Sweep SAR employs a one-dimensional phased-array feed of evenly spaced, individually controllable radar antennas arranged in rows.
Advantages of Sweep SAR:
High-resolution image
Wide area coverage (swath >240km)
A swath is the ground area that is imaged in a single pass of the sensor.
