Content : India’s uneasy balancing act in the Bay of Bengal Serving justices, but not justice India’s uneasy balancing act in the Bay of Bengal Positive Developments in Bay of Bengal Maritime Trade Rising trade volumes at key eastern ports: Visakhapatnam, Paradip, and Haldia. BIMSTEC Maritime Transport Cooperation Agreement (2024) signed to ease regulatory friction and reduce port costs. Infrastructure boost under Sagarmala Programme, improving logistics and port capacity. Coastal cargo movement has doubled in a decade, aided by GST cuts on bunker fuel and shipping incentives. Relevance : GS 2(International Relations ) ,GS 3(Infrastructure) Practice Question : India’s strategic ambitions in the Bay of Bengal are undermined by its own policy inconsistencies. Critically examine in the context of recent developments involving Bangladesh and BIMSTEC.(250 Words)   India’s Strategic Push for Regional Integration Emphasis on connectivity with Southeast Asia via eastern ports. India aims to be the regional integrator in Bay of Bengal through investments in port capacity and policy harmonization. BIMSTEC seen as key platform to counter China’s influence and deepen regional links. Controversial Decision: Withdrawal of Transshipment Facility to Bangladesh India withdrew a key facility that allowed Bangladesh to route third-country exports via Indian ports. Official reason: Terminal congestion, impacting Indian exporters. Perceived in Dhaka as a retaliatory move linked to Bangladesh’s growing ties with China and comments calling Indian NE states “landlocked”. Undermines India’s projection of the Northeast as a strategic connectivity hub. Diplomatic Fallout and Trade Tensions Bangladesh’s exports (especially garments) impacted due to reliance on Indian transshipment routes. Alternatives (e.g., via Sri Lanka) are costlier and slower. India later restricted imports of several Bangladeshi goods via land ports in Northeast, citing Dhaka’s earlier restrictions on Indian yarn. Dhaka perceives India’s actions as disproportionate and politically motivated. Implications for Regional Trust and BIMSTEC India’s actions introduce political conditionality in what was perceived as neutral trade infrastructure. Smaller BIMSTEC nations (Nepal, Bhutan, Myanmar) watching closely; fear India’s trade policy may become transactional and unpredictable. Perception risk: If India uses economic leverage for political signalling, it could erode regional goodwill and stall BIMSTEC progress. Credibility vs. Capacity India has superior port infrastructure and maritime logistics in the Bay. However, leadership in the region needs credibility—trust in consistent, rules-based facilitation. Without that, countries may hedge their bets and increase alignment with China or ASEAN-centric mechanisms. The Larger Strategic Dilemma Bay of Bengal is at a crossroads: It could become a bridge between South and Southeast Asia or a new arena for geopolitical contest. India must clearly separate economic integration from political signalling. Suggestion: India should consider a rules-based reinstatement mechanism for trade decisions like transshipment, to rebuild trust. Conclusion India’s actions may undermine cooperative regionalism if trade becomes a tool for political messaging. To sustain leadership and integration goals, India must balance strategic interests with transparent, trust-building economic policies. So far, the signals India has sent to its neighbours are mixed and potentially counterproductive.   Serving justices, but not justice Triggering Incident: Justice Varma Case March 14 fire at Justice Yashwant Varma’s official residence led to the discovery of half-burnt sacks of cash. Within 10 days, he was stripped of work and transferred; later faced impeachment proceedings. Supreme Court shared selective information (video, photos, redacted letters), but withheld crucial documents, including police and judicial reports. The alleged cash sacks are missing, reportedly removed by staff — a lapse in evidence security. Relevance : GS 2- Polity and Governance (Judiciary) , GS 4-Ethics, Integrity and Aptitude (Probity in Public Life) Practice Question : Judicial independence cannot be a cover for lack of accountability. Critically analyse the challenges posed by the ‘in-house procedure’ in ensuring transparency in judicial misconduct cases.(250 Words) Opaque ‘In-House Procedure’ of Judiciary Misconduct inquiries into higher judiciary handled by fellow judges only. Procedure is entirely confidential: complaints, inquiry status, and findings are not made public. No clear standards of evaluation or due process; findings aren’t appealable. Alleged lack of public accountability despite decisions affecting institutional integrity. Precedents Highlighting the Problem 2020: Andhra Pradesh CM’s allegations against Justice N.V. Ramana and Justice J.K. Maheshwari were dismissed summarily without transparent inquiry; no follow-up known. 2019: Sexual harassment allegations against CJI Ranjan Gogoi: Complainant denied legal assistance and access to the final report. Later reinstated with full back pay, despite earlier dismissal of her claims. SC instead investigated a non-existent “conspiracy” — a move seen as deflective. Justice Surya Kant (future CJI, Nov 2025): Faced corruption allegations regarding bail bribes and illegal assets. Justice A.K. Goel had raised red flags, yet there’s no evidence of inquiry before his elevation. Judiciary’s Credibility vs Independence Dilemma Judicial independence used as a reason for shielding internal inquiries from public view. However, secrecy undermines accountability, trust, and democratic values. Right to information, upheld by SC itself, contradicts the opacity in its own functioning. Call for Transparency & Reform Advocates for: Making in-house inquiry procedures, findings, and reports public. Ensuring external oversight or appellate mechanism to review findings. Transparency would: Deter misconduct, Enhance public trust, Support the judiciary’s own credibility. Conclusion The in-house procedure currently resembles secretive conclaves, lacking transparency and public scrutiny. Real judicial integrity requires accountability, not just independence. Without reform, public confidence in the judiciary will erode further — and rightly so.

Content : FATF condemns Pahalgam attack, to release report on ‘state-sponsored terror’ for first time New flowering plant species discovered in Aravali hills near Jaipur Analysing Internet access and digital skills in India What is the significance of the Shipki La pass? What are the ambiguities in India’s nuclear liability law? Registrar-General of India issues 2027 Census notification Ax-4 mission: ISRO, Axiom Space coordinate on crucial experiments before launch Forbidding Arabian desert once had a lush and bountiful chapter FATF condemns Pahalgam attack, to release report on ‘state-sponsored terror’ for first time Significance of Condemnation FATF officially condemned the Pahalgam terrorist attack (22 April 2025). It noted that such attacks “could not occur without money and means to transfer funds“—directly linking terror to financing channels. This is only the third condemnation of a terror attack by FATF in the last 10 years, highlighting the exceptional severity of this case. Relevance : GS 3(Internal Security) ,GS 2(International Relations) International Concern The international community reportedly exerted pressure, showing global consensus on the seriousness of the attack. Signals growing fatigue with Pakistan’s role in cross-border terror financing. Upcoming FATF Report FATF to release a report within a month that will: For the first time, officially include “state-sponsored terrorism” as a distinct source of terror financing. Mark a policy shift, aligning FATF’s global framework with India’s long-standing position on Pakistan. India’s National Risk Assessment is currently the only one acknowledging Pakistan’s state-sponsored terror as a financing risk. New FATF Tools FATF has developed a Terror Financing Risk & Context Toolkit for assessors. Aim: To prevent countries like Pakistan from misleading FATF using incomplete or false data. Enhances transparency and consistency in assessing terror financing threats. Public-Private Engagement FATF to host a webinar to sensitize public and private sector players on: Risks of terror financing. New and emerging threats. Importance of compliance and vigilance. India’s Dossier India reportedly sent a detailed dossier to FATF urging renewed scrutiny of Pakistan, possibly to push for re-greylisting. Aimed at exposing continued violations by Pakistan despite previous warnings. Broader Implications Policy shift at FATF adds global legitimacy to India’s narrative on Pakistan’s role in terrorism. May pave way for stricter sanctions, greylisting, or blacklisting, especially if Pakistan’s role is directly cited. Enhances international pressure on state sponsors of terrorism. FATF – Key Facts Established: 1989 at the G7 Summit in Paris. Headquarters: Paris, France. Members: 39 (including India). Secretariat: Hosted by the OECD. Main Objectives Combat money laundering, terror financing, and proliferation of weapons of mass destruction. Set global standards through 40 Recommendations. Key Tools Maintains “Grey List” (Jurisdictions under increased monitoring). Maintains “Black List” (High-risk jurisdictions with serious strategic deficiencies). Conducts Mutual Evaluations and follow-ups to assess compliance. India & FATF India became a member in 2010. Actively supports inclusion of Pakistan in the grey list for state-sponsored terror financing. Recent Developments FATF is now recognizing state-sponsored terrorism as a key source of terror financing. New flowering plant species discovered in Aravali hills near Jaipur About the Discovery A new flowering plant species named Portulaca bharat has been discovered near Galtaji Temple in the Aravalli Hills, Jaipur. Found growing in rock crevices of dry, rocky slopes in a semi-arid landscape. Discovered by Nishant Chauhan, member of the Satpura Biodiversity Conservation Society. Relevance : GS 3(Environment and Ecology) Botanical Significance Belongs to the Portulaca genus, known for: Succulent characteristics Water-storing tissues Adaptation to arid environments Portulaca bharat shows distinct morphological features, confirming it as a new species after scientific comparison and cultivation. Described in the international journal Phytotaxa. Ecological & Conservation Importance Classified as “Data Deficient” by IUCN Red List due to limited known population. Displays narrow endemism, found only at one location—Galtaji hills. Highly vulnerable to habitat degradation and climate change. Highlights the hidden biodiversity of the Aravalli range. Scientific & Institutional Collaboration Research supported by: Amber Srivastava (BSI) Sudhanshu Shekhar Dash & Sushil Kumar Singh (BSI, Kolkata & Dehradun) Cultivated and studied in Hamirpur (Himachal Pradesh) and Lucknow under controlled conditions. India’s Portulaca Diversity The genus has ~153 species globally, mainly in tropical/subtropical zones. India hosts 11 species, including 4 endemics. Most Indian species are adapted to dry, semi-arid habitats. Analysing Internet access and digital skills in India Survey Context First major dataset from CAMS (2022–2023) by NSSO, covering 3.02 lakh households and 12.99 lakh people. Aims to track progress on SDG 4.4 – digital skills for youth and adults. Relevance : GS 2(Social Issues) Internet Access – National Picture 76.3% households have broadband Internet access across India. Urban areas: 86.5% Rural areas: 71.2% Shows deep Internet penetration, but with regional and social disparities. Regional Disparities High broadband access (>90%): Delhi, Goa, Mizoram, Manipur, Sikkim, Haryana, Himachal Pradesh. Low broadband access (<70%): West Bengal, Andhra Pradesh, Odisha, Arunachal Pradesh. Social Group Disparities General category households: 84.1% have broadband. OBCs: 77.5%, SCs: 69.1%, STs: 64.8%. Indicates a digital caste divide, with marginalized groups lagging. Income-Based Digital Divide Poorest decile (bottom 10%): 71.6% households lack broadband. Richest decile (top 10%): Only 1.9% lack broadband. Even second lowest decile shows 56.2% connectivity → shows improvement across income bands. Economic status = key driver of digital access. Mobile Phone Access Mobile/telephone access: 94.2% rural, 97.1% urban households. Mobile usage (age 15+): 83.9% rural, 92.4% urban. However, exclusive mobile use is low among women and lower castes, especially in rural areas: Rural general category women: only 25.3% use mobile exclusively. Urban women: 51.2%. Even worse for SCs, STs, OBCs. Technology Level in Use Only 50% rural and 70% urban users use 4G. 40.4% of Indians still use older mobile technologies (2G/3G). 5G adoption: negligible. Digital Skills Gaps Internet usage (15+ age group): 53.6% rural, 74% urban. Email use: 20% rural, 40% urban. Copy-paste skills: 40% rural, 60% urban. Spreadsheet arithmetic skills: very low. Online banking skills: only 37.8% of population 15+ can perform. Policy Implications Clear digital divide across regions, caste groups, genders, and income levels. Digital skills lag behind access, especially in rural areas and among marginalized groups. Government should: Subsidize broadband for the poor (as done for water/electricity). Focus on basic digital literacy training at the grassroots. Ensure equity in access to support goals under SDG 4. What is the significance of the Shipki La pass? Historical Importance Located in Kinnaur district, Himachal Pradesh at an altitude of 3,930 m. A historic Indo-Tibetan trade route — operational since at least the 15th century, likely earlier. Folklore-based trade oath symbolized enduring cross-border trust and peace. Relevance : GS 1(Culture ,Heritage ,Geography) ,GS 3(Infrastructure ,Trade)   Why Trade Stopped Disrupted after the Sino-India War of 1962. Further breakdown due to Doklam standoff (2017) and COVID-19 pandemic. Commercial trade remains suspended, though local aspirations remain high. Recent Developments Himachal Pradesh CM reopened the pass for Indian tourists (no permit now needed; Aadhaar card sufficient). Move has revived hopes for trade and religious tourism among locals. Trade: Nature of Goods Exchanged Imports from Tibet: wool, yaks, goatskins, thangkas, prayer items, turquoise, gold. Exports from India: grains, spices, dried fruits, copper utensils, iron tools, tobacco. Trade supported local crafts and jewelry industries (e.g. Kinnauri ornaments). Why Reopening Matters Despite Low Trade Volume Can shorten the Delhi–Mansarovar pilgrimage by 14 days — big religious tourism boost. Generates employment, revives hospitality sector, and encourages infrastructure growth. Serves as a community-led diplomatic model — fostering peace through cultural-economic ties. Cultural & Spiritual Links People on both sides share pastoral lifestyles, similar surnames (e.g. Namgyal). Dominant religion: Buddhism — shared monastic traditions, festivals, and spiritual practices. Reflects civilisational continuity, unlike more fractured India–Pakistan cross-border ties. Policy & Strategic Implications Reopening can act as a “soft corridor” for India-China people-to-people engagement. Advocated by Kinnaur Indo-China Trade Association; State Government plans to push MEA for trade revival. Could become a model for heritage-based diplomacy and inclusive border development. What are the ambiguities in India’s nuclear liability law? Basic Provisions of CLNDA Enacted in 2010 to provide compensation for nuclear damage and ensure a mechanism for speedy claims. Strict and no-fault liability on the operator (NPCIL in India’s case). Operator’s liability is capped at ₹1,500 crore; Government steps in beyond that up to ~₹2,100–₹2,300 crore. India acceded to the Convention on Supplementary Compensation (CSC) in 2016. Relevance : GS 2(Governance ) CLNDA’s Unique Supplier Liability Clause Unlike CSC, India’s law allows operator to seek recourse from the supplier under three conditions: Section 17(a): If expressly mentioned in the contract. Section 17(b): If damage was caused by defective equipment/services (even if not in contract). Section 17(c): If damage was caused by intentional misconduct. Key Ambiguities Section 17(b): Goes beyond international norms, creating automatic liability for suppliers if equipment is defective. Section 46: States CLNDA does not prevent other legal proceedings under other laws (e.g. tort law), potentially exposing suppliers to unlimited civil and criminal liability. No clear definition of “nuclear damage” under CLNDA → increases legal uncertainty. Concerns of Foreign & Domestic Suppliers Fear of uncapped liability, especially due to Section 46, discouraging investment. Absence of clarity on insurance requirements and coverage for suppliers. Potential for class-action lawsuits or civil suits, despite CSC’s intention to limit claims to operator alone. Impact on Projects Major foreign-backed projects like: Jaitapur (France), Kovvada (USA) remain stalled. Only Kudankulam (Russia) has progressed — initiated before CLNDA, operates under a separate framework. Government’s Stand Claims CLNDA is in line with CSC and Section 17(b) is permissive, not mandatory. However, legal experts assert each subsection (17a, 17b, 17c) is independent — supplier can be sued even if contract doesn’t mention it. Government stance on Parliament debates holds little weight in court; statutory language prevails in legal trials. Broader Implications Suppliers demand amendment or legal clarification for protection. Law intended to protect victims and promote accountability post-Bhopal tragedy, but ends up deterring foreign investment. Without reform, India risks missing out on clean nuclear energy expansion critical for energy security and climate goals. Registrar-General of India issues 2027 Census notification Timeline and Reference Dates Census Year: 2027 Reference Date: March 1, 2027: For most parts of India October 1, 2026: For snow-bound and non-synchronous areas of: Ladakh Jammu & Kashmir Himachal Pradesh Uttarakhand Relevance : GS 2(Governance) Freezing of Administrative Boundaries With the Gazette notification issued under Section 3 of the Census Act, 1948, freezing of administrative boundaries comes into effect. States cannot alter boundaries of districts, tehsils, police stations, etc., until the Census process concludes. This is crucial for maintaining consistency in enumeration blocks. Digital Census Features The 2027 Census will be digitally driven: Use of mobile applications by enumerators Option for self-enumeration by the public First-time use of end-to-end digital data collection in India’s census history.

Forbidding Arabian desert once had a lush and bountiful chapter Geographical Context Arabian Peninsula lies in the world’s driest desert belt — from the Sahara to the Thar Desert. It has long served as a major biogeographical barrier, limiting migration of humans and animals between Africa and Eurasia. Arid conditions believed to have persisted for at least 11 million years. Relevance : GS 1(Geography) New Scientific Findings Recent research published in Nature suggests periodic wet/humid phases in the past 8 million years. These phases transformed Arabia into grasslands with rivers and lakes, enabling migration of animals and humans. Speleothems (cave mineral formations) found in 7 cave systems in central Saudi Arabia serve as key evidence. Humidity Cycles & Dating 22 speleothem samples dated using Uranium-Thorium/Lead radiometric methods. Earliest wet period: 7.44 – 6.25 million years ago. Latest wet periods: 530,000 – 60,000 years ago. Wet phases became shorter and less intense over time due to: Weakening of monsoonal influence. Growth of Northern Hemisphere ice sheets in the Pleistocene. Ecological & Archaeological Evidence Fossils of hippos, crocodiles, horses show wetland ecosystems existed ~74,000 years ago. Discovery of 10,000+ ancient lakes and archaeological sites like Jubbah Oasis with tools dating back 500,000 years. Indicates early human and animal migration corridors through Arabia during humid periods. Human Evolution & Migration Earlier assumption: Arabia was uninhabitable until domestication of camels/goats a few thousand years ago. New evidence supports ‘Green Arabia Hypothesis’ — Arabia as a critical route in Out of Africa migration. Shows that Homo sapiens and other hominins used Arabia as a transit zone during humid phases. Scientific Significance Reshapes theories of early human migration and biogeographic exchanges. Highlights role of climate variability in shaping migration, survival, and extinction. Shows how environmental corridors opened and closed over millennia due to climate shifts. Lessons for the Present Historical patterns show that humans flourished in wet climates, and migrated or declined during arid ones. Raises a cautionary note: Could climate change today trigger new human migrations? Modern dependence on technology (e.g., air conditioning) may delay, but not prevent, migration due to heat and water scarcity.
