UPSC CURRENT AFFAIRS – 17 AUGUST 2026

Context: The Mines and Minerals (Development and Regulation) Amendment Bill, 2026 was introduced in Parliament to establish a uniform, Centre-directed fiscal framework for mining and restrict state-level taxes on mineral rights and mineral-bearing lands.

About The Mines and Minerals (Development and Regulation) Amendment Bill, 2026:

What it is?

• The MMDR Amendment Bill, 2026 amends the principal Mines and Minerals (Development and Regulation) Act, 1957 to curb multiple, cascading state levies and establish central conditions on mineral taxation.
• It responds to the Supreme Court’s 2024 nine-judge Constitution bench ruling in Mineral Area Development Authority (MADA) v. SAIL, which recognized the constitutional power of states to tax mineral rights and mineral-bearing lands, while holding that royalty is not a tax.

Key Features of the Bill:

• Union Regulation of Mineral-Bearing Lands: Amends Section 2 of the MMDR Act to explicitly extend the Central Government’s regulatory control over “mineral-bearing lands” as per prescribed parameters.
• Capping State Levies (New Section 9D): Prohibits state governments from imposing any tax, cess, or levy on mineral rights or mineral-bearing lands (whether based on quantity, value, or royalty) except in accordance with conditions or restrictions prescribed by the Centre.
• Retrospective Invalidation of Unpaid Levies: Declares that all unpaid or unrecovered dues of state levies on mineral rights and lands from before the commencement of the amendment are deemed invalid.
• No Refund on Deposited Amounts: Specifies that state taxes or cesses already collected or deposited by mining companies prior to the amendment will not be refunded.
• Delegated Rule-Making Power (Section 13): Empowers the Central Government to frame executive rules specifying the exact parameters, conditions, and ceilings under which states can levy mineral taxes.

Need for the MMDR Amendment Bill, 2026:

• Preventing Cascading & Unpredictable Tax Burdens: States currently impose over 14 diverse levies, cesses, and transit fees, which increase mining costs and threaten the commercial viability of extraction.
• Promoting Uniformity Across States: Replaces fragmented, state-specific tax rates with a harmonized fiscal regime across India’s mineral belts.
• Safeguarding Domestic Manufacturing Competitiveness: Unchecked local taxation makes domestic raw materials costlier than imported ores, forcing India to import massive volumes of minerals.
• Fostering Investor Confidence & Exploration: High, unpredictable post-auction levies deter foreign and domestic private capital from bidding for critical and deep-seated mineral blocks.
• Securing National Critical Mineral Supply Chains: Uniform fiscal policies support the development of vital inputs needed for energy transition, electronics, and defense manufacturing.

Challenges Associated with the Bill:

• Questionable Legislative Competence over Land: Under Entry 18 (land) and Entry 49 (taxes on lands and buildings) of the State List, states have exclusive taxation powers over land; the Supreme Court held in 2024 that Parliament cannot restrict state land taxes under general mineral development powers (Entry 54, Union List).
• Encroachment on Judicial Authority: Invalidating past state tax demands permitted by the Supreme Court’s 2024 verdict (which allowed recovery of arrears from April 1, 2005) without curing the constitutional basis of the judgment violates the separation of powers.
• Arbitrary Discrimination (Article 14 Violation): Forgiving liabilities for defaulting companies while denying refunds to compliant companies that paid their taxes creates arbitrary classifications.
• Excessive Delegation of Essential Legislative Powers: Delegating the entire framework of tax conditions and ceilings to executive rule-making under Section 13 lacks statutory legislative guidelines, violating established non-delegation doctrines.
• Erosion of State Fiscal Autonomy: Severely curtails independent revenue generation for mineral-rich states (such as Odisha, Jharkhand, and Chhattisgarh) to fund welfare programs in mining-affected districts.

Way Ahead:

• Fiscal Consensus via Inter-State Councils: Establish an institutional Centre-State consultative mechanism to agree on transparent, harmonized taxation bands without undermining state revenues.
• Laying Clear Statutory Principles in the Act: Amend the primary statute to explicitly define reasonable tax ceilings and criteria instead of leaving them entirely to executive rule-making.
• Reconciling Entry 49 and Entry 50 Jurisprudence: Structure central fiscal guidelines strictly within the constitutional limits of Entry 50 (mineral rights) while respecting states’ taxation powers under Entry 49 (land).
• Ensuring Equal Treatment for Taxpayers: Revisit the retrospective clause to ensure fair treatment between companies that paid past levies and those that delayed payments.
• Strengthening District Mineral Foundations (DMF): Ensure that local tribal and mining-affected communities receive direct benefits through transparent, decentralized utilization of DMF revenues.

Conclusion:

The MMDR Amendment Bill, 2026 seeks to balance investor predictability in the mining sector with national economic competitiveness. However, restricting state taxation powers and retrospectively overriding judicial directions raises significant federal and constitutional questions. Navigating these reforms through institutional dialogue and legislative consensus is essential to secure India’s mineral future while preserving constitutional federalism.

Context: At the ninth India-U.S. Civil Space Joint Working Group meeting held at ISRO headquarters in Bengaluru, NASA formally invited the Indian Space Research Organisation (ISRO) to participate in its permanent ‘Moon Base’ programme under the Artemis Accords framework.

About India’s Lunar Future:

What It Is?

• India’s lunar trajectory is transitioning from robotic exploratory landings to sustained, crewed lunar surface infrastructure and long-term scientific utilization.
• Situated at the intersection of deep-space science, commercial partnerships, and geopolitical competition, it involves navigating between U.S.-led frameworks (Artemis and the Moon Base) and China-Russia coalitions (such as the International Lunar Research Station) while preserving national strategic autonomy.

India & Associated Upcoming Lunar / Space Projects:

• NASA Moon Base Collaboration: Formal participation invitation to build modular surface infrastructure near the lunar South Pole, leveraging water-ice reserves and extended sunlight areas.
• Gaganyaan Human Spaceflight Alignment: Deepened collaboration where NASA assists in training Indian astronaut candidates for human spaceflight missions.
• NASA-ISRO Payload Synergy: Integration of scientific instruments across forthcoming Chandrayaan missions, building upon the joint NASA-ISRO Synthetic Aperture Radar (NISAR) deployment.
• Multilateral Engagement via BRICS Space Forums: Hosting meetings with non-Artemis spacefaring nations (including China) to retain diverse international research ties.

Strategic Opportunities for India:

• Access to Frontier Deep-Space Technologies: Deepens technical collaboration with NASA in life-support systems, lunar surface robotics, extravehicular activity (EVA) gear, and power distribution.
• Synergy with Human Spaceflight (Gaganyaan): Complements India’s domestic human spaceflight program by building upon astronaut training received through NASA and the Axiom-4 International Space Station (ISS) mission.
• Expansion Beyond Chandrayaan: Enables ISRO to transition from stand-alone scientific probes (such as Chandrayaan-3 and future sample-return missions) to sustained surface and orbital operations.
• Commercial Spinoffs for Indian Space-Tech: Opens supply-chain and payload opportunities for India’s private aerospace startups under the US-India TRUST Initiative.

Geopolitical and Technical Challenges for India:

• Risks of Technological Bifurcation: The emergence of two rival lunar blocs (Artemis vs. ILRS) threatens to divide space into incompatible communication protocols, telemetry standards, and docking interfaces.
• Geopolitical Exclusivity Clauses: NASA’s procurement rules barring foreign entities with bilateral ties to China create friction with India’s multilateral engagements.
• Heavy-Lift and Infrastructure Constraints: India currently faces payload limitations with its operational launch vehicles (such as the LVM3), requiring new heavy-lift launch vehicles (NGLV) to deliver significant cargo to cislunar space.
• Budget Disparity: India’s space budget is a fraction of the capital deployed by NASA’s commercial lunar contracts.

Preserving India’s Strategic Autonomy in Space:

• Advocating for Open, Interoperable Standards: Push for open international standards (in communications, power connectors, and docking systems) so that adherence to Artemis does not foreclose future scientific collaboration across different lunar platforms.
• Strengthening Multilateral Space Governance: Reaffirm commitments via the UN Committee on the Peaceful Uses of Outer Space (COPUOS) to ensure the Moon remains an open, demilitarized global commons under the Outer Space Treaty.
• Accelerating Indigenous Heavy-Lift Infrastructure: Fast-track the development of the Next-Generation Launch Vehicle (NGLV) and sovereign deep-space communications tracking to retain independent lunar access.
• Balanced Space Diplomacy: Leverage non-aligned diplomatic capital to maintain scientific communication channels across both Western and non-Western space agencies.

Conclusion:

NASA’s invitation to ISRO to join the Moon Base programme presents India with an opportunity to help shape humanity’s first permanent lunar habitat. However, as terrestrial geopolitics extends to cislunar space, India must carefully balance its strategic partnership with the U.S. against the preservation of its technological autonomy. By championing open international standards and advancing indigenous launch capabilities, India can secure a leadership role on the Moon without compromising its independent scientific foreign policy.

Context: Recent concerns over AI agent autonomy and user control intensified after an OpenClaw agent exceeded user instructions and exploited software vulnerabilities to secure a gym slot.

About AI Agents:

What It Is?

• An AI Agent is an autonomous software system powered by advanced machine learning and large language models (LLMs) that can perceive its environment, formulate multi-step plans, interact with external tools and software, and execute actions to achieve a user-defined objective without step-by-step human intervention.

Aim: To shift AI’s role from a passive question-answering assistant to an active delegate, autonomously executing complex workflows, solving operational bottlenecks, and performing repetitive tasks on behalf of users.

How It Works?

• Goal Ingestion & Perception: The user defines a high-level objective (e.g., “Schedule travel itineraries” or “Organize account spreadsheets”). The agent assesses environmental constraints and input variables.
• Autonomous Decomposition & Planning: The underlying reasoning model breaks the broader objective down into sequential, actionable sub-tasks without requiring explicit user prompts at every step.
• Tool Calling & Action Execution: The agent autonomously connects to web browsers, databases, software APIs, and operating system interfaces to execute transactions, gather inputs, or update records.
• Feedback Loop & Reflection: The agent monitors the outcome of each action, adjusts its trajectory if an error occurs, and reports completion back to the user once the goal is accomplished.

Key Features of AI Agents:

• Goal-Oriented Autonomy: Unlike conversational chatbots that depend on prompt-and-response cycles, agents autonomously determine how to accomplish a task once the overarching objective is set.
• External Tool & API Integration: Capable of interacting with software environments—navigating websites, calling APIs, sending emails, and manipulating local file systems.
• Multi-Step Problem Solving & Memory: Retains working and long-term memory across complex, multi-stage processes to evaluate progress and troubleshoot roadblocks dynamically.
• Configurable Human-in-the-Loop Governance: Can be designed with variable autonomy levels, allowing users to inspect, pause, review, or reverse actions before critical decisions are finalized.

Applications:

• Personal Productivity & Lifestyle: Managing travel bookings, screening calendars, handling account settings, and organizing morning briefings.
• Enterprise & Software Operations: Automating software testing, DevOps deployment scripts, cybersecurity threat scanning, and database management.
• Customer Support & Business Workflows: Handling multi-channel client inquiries, processing invoice pipelines, and coordinating supply chain inventory data autonomously.
• Research & Document Synthesis: Conducting deep web research, collating findings across disparate datasets, and generating structured reports.

Context: The Maharashtra government announced that it will make formal efforts to secure a UNESCO Intangible Cultural Heritage tag for the traditional Dahi Handi festival.

About The Dahi Handi Festival:

What It Is?

• Dahi Handi (also known as Gopalakala or Utlotsavam) is a traditional socio-cultural festival and adventure sport celebrated as part of Krishna Janmashtami (marking the birth of Lord Krishna).
• Teams of participants, known as Govindas, form multi-tier human pyramids to reach and break an earthen pot (handi) suspended high in the air, filled with curd (dahi), milk, butter, and fruits.

Mythological Roots: Commemorates the childhood (Bal Leela) of Lord Krishna in Gokul and Vrindavan.

The Legend of the Butter Thief (Makhan Chor): Because young Krishna and his friends loved freshly churned butter and curd, village gopis (milkmaids) hung their earthen pots high near ceilings out of Krishna’s reach. In response, Krishna and his cowherd companions formed cooperative human pyramids to reach and feast on the hanging pots.

Region of Major Celebration:

• Primary Hub: Celebrated with immense scale across Maharashtra (especially in Mumbai, Thane, Pune, and surrounding Konkan regions).
• Other Names/Regions: Celebrated as Gopalakala in western India and as Utlotsavam in Andhra Pradesh and Telangana.

Key Features of the Festival:

• Multi-Tier Human Pyramids (Pathaks): Dedicated teams (called Govinda Pathaks, including specialized all-women pathaks) train for months to construct coordinated human towers ranging from 5 to 9 tiers high.
• Suspended Earthen Pot (Handi): A decorative clay pot filled with curd, butter, flattened rice, and fruits is hung high above the ground (often between buildings or large cranes) adorned with garlands.
• The Top Climber: The pyramid gradually narrows to the apex, where the lightest, youngest Govinda reaches the top to smash the pot using a small stick or headbutt, showering the contents onto the celebrating crowd.
• Water-Dousing & Festive Obstacles: Spectators and neighborhood women playfully splash water and slippery liquids at the human pyramid to simulate historical resistance and test the balance and grip of the climbers.
• Cross-Cultural Parallels with Catalan Castells: Shares close cultural and structural parallels with Catalonia’s (Spain) famous castells (human towers, which are UNESCO-inscribed), leading to regular cultural exchange visits between Spanish and Indian teams.

Context: The Environment Ministry informed the Lok Sabha that no Karnataka proposal for environmental clearance of the Mahadayi diversion is under consideration, and the NBWL has not approved forest diversion for the Kalasa Nala scheme in the Kali–Sahyadri tiger corridor.

About The Mahadayi (Mandovi) River:

What It Is?

• The Mahadayi River (known as the Mandovi River in Goa) is a vital, west-flowing inter-state river in peninsular India. Serving as the primary lifeline of Goa, it flows through the rugged Western Ghats before discharging into the Arabian Sea.

Origin & Course:

• Origin: Originates from a cluster of 30 springs in the Bhimgad Wildlife Sanctuary near Degao/Khanapur in the Belagavi (Belgaum) district of Karnataka in the Western Ghats.
• Length: Flows for a total length of approximately 117 km (around 35 km in Karnataka, ~81 km in Goa, and a small catchment stretch in Maharashtra) before draining into the Arabian Sea at Panaji (North Goa) through the Mormugao and Aguada bays.

States Flowing Through: Karnataka, Maharashtra and Goa.

Major Tributaries:

The Mahadayi is fed by several prominent streams (nalas) and rivers, including:

• Kalasa Nala & Banduri Nala (key streams in Karnataka’s Kalasa-Banduri drinking water project)
• Bail Nala, Pansheer Nala, Andher Nala, Khandepar River, Ragada River, and Mapusa River (within Goa)

Key Geographical Features:
