UPSC CSE Current Affairs — 25 August 2026

China continues to claim Arunachal Pradesh as 'Zangnan,' asserting it is part of South Tibet, while India firmly maintains the state is an integral part of its territory. The dispute centres on the McMahon Line drawn at the 1914 Simla Convention, which China never accepted. Tensions have periodically risen over infrastructure development, Chinese renaming of places in Arunachal, and troop movements along the Line of Actual Control, making this one of the most persistent unresolved bilateral territorial disputes in Asia.

The Arunachal Pradesh dispute is rooted in competing historical claims over the eastern sector of the India-China boundary. The McMahon Line, established during the 1914 Simla Convention between British India and Tibetan representatives, defines approximately 890 km of the boundary between India and what is now China's Tibet Autonomous Region. China rejects this line on the grounds that Tibet lacked the sovereign authority to sign such an agreement, and that China was not a signatory.

China refers to Arunachal Pradesh as 'Zangnan' (South Tibet) and has periodically 'renamed' locations within it using standardised Chinese names — doing so in multiple rounds (2017, 2021, 2023). This renaming exercise is a soft-power assertion of territorial claim, not a de facto administrative change.

India's legal and constitutional position is unambiguous: Arunachal Pradesh became a Union Territory in 1972 and a full state on 20 February 1987. It has an elected government, sends members to Parliament, and is fully integrated into India's federal structure.

The broader boundary question is managed through the Special Representatives mechanism, established in 2003, under which both sides have held over 20 rounds of talks without a final settlement. The 1993 and 1996 bilateral agreements on maintaining peace and tranquility along the LAC remain the operative frameworks. The Tawang region within Arunachal carries additional strategic and religious significance — it houses one of the largest Tibetan Buddhist monasteries outside Tibet, making it culturally contested as well.

The Supreme Court on August 24 restored an election petition filed by Congress advocate Hafiz Rashid Ahmed Choudhury challenging the election of a BJP MP from Assam. The High Court had dismissed the petition without affording the petitioner an opportunity to be heard, which the Supreme Court found to be a procedural violation. The bench set aside the High Court order and directed a fresh hearing, reaffirming that election petitions cannot be dismissed without hearing the petitioner.

This ruling touches a foundational principle in election law and civil procedure: audi alteram partem — no party should be condemned unheard. Under the Representation of the People Act, 1951 (RPA), election petitions are special statutory proceedings governed by strict procedural rules. Sections 80 to 84 govern filing, while Section 86 governs dismissal. The High Court has the power under Section 86 to dismiss a petition at the threshold, but only for specific grounds — if it does not comply with Sections 81, 82, or 117. Even then, natural justice requires the petitioner be heard before dismissal.

The Supreme Court's intervention here reasserts a hierarchy: procedural powers conferred by statute cannot override constitutional guarantees of fair hearing. This is significant for election law because High Courts often use threshold powers to dismiss petitions quickly, and the line between legitimate summary dismissal and premature termination is frequently litigated.

For CLAT PG aspirants, the key legal test is whether dismissal occurred without hearing — if yes, the order is procedurally infirm regardless of the merits of the election challenge. The court is not ruling on whether the BJP MP's election was valid; it is only restoring the petition to ensure the challenge is heard. This distinction — between procedure and merits — is exactly what passage-based questions in CLAT PG test.

India is pivoting toward regenerative agriculture — a farming approach that restores soil health, enhances biodiversity, and sequesters carbon rather than depleting land. Unlike conventional Green Revolution methods reliant on synthetic fertilisers and pesticides, regenerative practices include natural farming, agroforestry, cover cropping, and zero-budget natural farming. The government is promoting these through schemes like the Paramparagat Krishi Vikas Yojana and the National Mission for Sustainable Agriculture, aiming to build climate resilience while reducing input costs for farmers.

Regenerative agriculture is a system-level approach to farming that goes beyond sustainability — the goal is not merely to sustain existing soil quality but to actively restore degraded land. Its core principles include: minimising tillage to protect soil structure, maintaining continuous ground cover, promoting plant diversity, integrating livestock, and eliminating or sharply reducing synthetic chemical inputs.

In the Indian context, this connects to several converging policy concerns. First, the long-term consequences of the Green Revolution — which dramatically raised yields but depleted aquifers, caused soil salinisation, and created heavy pesticide dependency — have become undeniable in states like Punjab and Haryana. Second, climate change is increasing the frequency of drought and flooding events, making soil organic matter (which improves water retention and aeration) a strategic resource. Third, the rising cost of chemical inputs is squeezing farm incomes, making low-external-input farming financially attractive.

Key government interventions include: Paramparagat Krishi Vikas Yojana (PKVY), which promotes organic farming clusters; Zero Budget Natural Farming (ZBNF), championed in Andhra Pradesh and adopted under the National Mission for Natural Farming (NMNF); and the National Mission for Sustainable Agriculture (NMSA) under the National Action Plan on Climate Change. NABARD plays a crucial role by financing Farmer Producer Organisations (FPOs) and watershed development projects that underpin the transition to regenerative systems. The conceptual link between soil carbon sequestration and India's NDC commitments under the Paris Agreement also makes this topic relevant to climate policy questions.

The Department of Defence Production (DDP) has notified the 6th Positive Indigenisation List (PIL) under the Aatmanirbhar Bharat initiative, covering 405 strategically important defence items. These items — including ammunition, weapons systems, and high-technology components — are now reserved exclusively for domestic procurement, barring import. The cumulative count across all six PILs now stands at over 4,500 items, signalling India's sustained push to reduce defence import dependence and build indigenous manufacturing capacity.

The Positive Indigenisation List (PIL) is a central instrument of India's defence self-reliance strategy under Aatmanirbhar Bharat. Notified by the Department of Defence Production (DDP), which operates under the Ministry of Defence, each PIL designates specific defence items — ranging from simple spares to complex weapons systems — that the Indian Armed Forces must procure exclusively from domestic manufacturers after a stipulated timeline. Import of listed items is prohibited beyond that date.

The mechanism works on a time-bound import embargo: once an item enters the PIL, the private sector and Defence Public Sector Undertakings (DPSUs) are incentivised to develop domestic production capability before the embargo kicks in. This creates a guaranteed demand signal for Indian industry.

The policy problem being solved is structural: India has historically been among the world's largest defence importers, spending billions in foreign exchange on items that could potentially be manufactured domestically. The PILs directly address this by creating a sequenced roadmap for import substitution.

For competitive exams, the key distinctions are: (1) DDP is the notifying authority, not MoD directly; (2) PILs cover both ammunition and high-technology systems — not just basic equipment; (3) each successive list expands scope, testing whether aspirants track the list number and cumulative count; (4) the policy connects to Priority Sector Lending in a RBI context — defence manufacturing MSMEs benefiting from these contracts can access PSL-eligible credit. NABARD aspirants should note rural defence manufacturing clusters as a rural industrial development angle.

IDFC FIRST Bank has partnered with IIM Calcutta Innovation Park to launch a ₹2 crore national incubation programme targeting sustainable and circular economy startups. The initiative aims to accelerate early-stage ventures focused on environmental sustainability, resource efficiency, and green business models. By combining the bank's financial reach with IIM Calcutta's academic and innovation ecosystem, the programme blends corporate CSR priorities with structured startup mentorship and funding support for climate-aligned entrepreneurs across India.

This initiative sits at the intersection of three exam-relevant themes: CSR obligations of private banks, green finance, and the circular economy as a policy concept.

The circular economy model contrasts sharply with the traditional linear 'take-make-dispose' approach. Instead, it emphasises resource reuse, recycling, and regeneration — reducing waste and environmental pressure. India's policy push toward circular economy principles is visible in the Extended Producer Responsibility (EPR) frameworks for plastics and e-waste, the National Resource Efficiency Policy (2019), and India's climate commitments under the Paris Agreement.

For banks like IDFC FIRST, funding such an incubator can qualify as a CSR expenditure under Schedule VII of the Companies Act, 2013, which permits CSR spending on environmental sustainability, technology incubators within academic institutions, and rural development. Partnering with an IIM-affiliated innovation park also satisfies the 'technology incubator' carve-out explicitly listed in Schedule VII.

From RBI's angle, this programme reflects the push for sustainable finance. RBI's Discussion Paper on Climate Risk and Sustainable Finance (2022) and the Business Responsibility and Sustainability Report (BRSR) framework nudge banks toward green lending and ESG-aligned investments. Startup incubation for circular economy ventures is a soft form of green credit channel creation.

For SEBI, ESG disclosure norms and BRSR requirements for listed companies are the connective tissue — IDFC FIRST Bank being a listed entity must report such sustainability initiatives.

The fifth edition of SEMICON India will be inaugurated by Prime Minister Narendra Modi on 17 September 2026 at Yashobhoomi, New Delhi, running through 19 September. The event, India's largest semiconductor-focused gathering, brings together global chipmakers, policymakers, and researchers. It reflects India's push under the India Semiconductor Mission to build domestic fabrication capacity and reduce dependence on chip imports amid global supply-chain vulnerabilities exposed after the COVID-19 pandemic.

Semiconductors are materials — typically silicon — whose electrical conductivity lies between that of conductors and insulators. This property makes them the foundational material for transistors, integrated circuits, and virtually every modern electronic device. The global semiconductor industry is a roughly $600-billion market dominated by a handful of countries: Taiwan (TSMC), South Korea (Samsung, SK Hynix), the United States (Intel, Qualcomm), and the Netherlands (ASML for lithography equipment). China's exclusion from advanced chip supply chains through US export controls has made semiconductor self-reliance a geopolitical priority worldwide.

India's policy response is the India Semiconductor Mission (ISM), launched under the ₹76,000-crore (approximately $10 billion) Production-Linked Incentive scheme for semiconductors and display fabs, announced in December 2021. ISM sits under the Ministry of Electronics and Information Technology (MeitY). Key approved projects include Tata Electronics' fab in Dholera (Gujarat) using 28nm technology in partnership with Taiwan's Powerchip, and a Tata OSAT (Outsourced Semiconductor Assembly and Test) facility in Assam. Micron Technology (US) is building an ATMP (Assembly, Testing, Marking and Packaging) unit in Sanand, Gujarat.

SEMICON India, organised by SEMI (global industry association) and MeitY, is India's flagship platform for this ecosystem. The choice of Yashobhoomi — India International Convention and Expo Centre in Dwarka, New Delhi — underlines the scale of ambition. For UPSC, the examiner tests the policy architecture (ISM, PLI), the technology distinctions (fab vs ATMP vs OSAT), and India's position in the global semiconductor value chain.

Defence Minister Rajnath Singh and West Bengal Chief Minister Mamata Banerjee jointly performed the Bhumi Pujan for five expansion projects at the Ordnance Factory Dum Dum in Kolkata. The projects aim to enhance domestic defence manufacturing capacity under the Atmanirbhar Bharat initiative. The ceremony marked rare Centre-state cooperation on a defence infrastructure project, with the ordnance factory falling under the Ministry of Defence's Ordnance Factory Board successor entities established after the 2021 corporatisation.

Ordnance Factory Dum Dum is one of India's oldest defence manufacturing establishments, historically under the Ordnance Factories Board (OFB). In October 2021, the Government of India dissolved the OFB and corporatised its 41 ordnance factories into seven new Defence Public Sector Undertakings (DPSUs). This restructuring was aimed at improving efficiency, accountability, and competitiveness in line with India's Atmanirbhar Bharat defence policy.

The seven new DPSUs formed from OFB corporatisation are: Munitions India Limited, Armoured Vehicles Nigam Limited (AVNL), Advanced Weapons and Equipment India Limited, Troop Comforts Limited, Yantra India Limited, India Optel Limited, and Gliders India Limited.

Dum Dum Ordnance Factory, located in Kolkata, specialises in small arms ammunition and has historical significance — the 'Dum Dum bullet' (expanding bullet) takes its name from this location. It now falls under Munitions India Limited.

The Bhumi Pujan for five new projects signals continued capital investment in legacy defence infrastructure under the Make in India and Atmanirbhar Bharat defence frameworks. The joint participation of the Raksha Mantri and the West Bengal CM underscores that defence manufacturing facilities, though under Central government jurisdiction, require state-level cooperation for land, logistics, and labour — a federalism dimension the UPSC examiner may probe.
