  • RBI holds repo rate; core versus headline inflation debate

    Why in the News

    The Reserve Bank of India (RBI) held the repo rate at 5.25%. Economists are divided over whether the central bank is anchoring policy to headline CPI or to core inflation, which strips out food and fuel.

    What is core inflation?

    1. Definition: Core inflation measures price change after removing volatile food and fuel components, showing the underlying, persistent trend.
    2. Why it matters: Monetary policy affects demand-driven prices, not a monsoon-driven food spike, so core is a cleaner signal for interest-rate decisions.

    Why is the anchor contested?

    1. Mandate is headline: The RBI’s legal target is headline retail inflation around 4%, not core, so leaning on core risks appearing to shift the goalpost.
    2. Food weight is large: Food is a large share of India’s consumption basket, so ignoring it understates the inflation households actually face.
    3. Credibility risk: Frequent redefinition of the operative measure weakens the predictability that anchors inflation expectations.

    Conclusion

    The rate hold reflects a judgement that underlying price pressure is easing even as headline stays elevated. The next milestone is whether food inflation cools enough to align headline with the target.

    PYQ Relevance

    [UPSC 2024] What are the causes of persistent high food inflation in India? Comment on the effectiveness of the monetary policy of the RBI to control this type of inflation.

    Linkage: The PYQ examines the limits of monetary policy in controlling persistent food-driven inflation. The debate over headline versus core inflation highlights how the RBI balances its inflation mandate with supply-side food shocks.

  • India crosses 300 GW of non-fossil power capacity

    Why in the News

    India’s non-fossil fuel capacity has crossed 300 GW, achieving about 60% of the 500 GW target for 2030. The key challenge is converting installed capacity into actual electricity generation.

    What is the 500 GW Target?

    1. Panchamrit pledge: India committed at COP26, Glasgow (2021) to achieve 500 GW of non-fossil electricity capacity by 2030.
    2. Coverage: Includes solar, wind, hydro and nuclear capacity.
    3. Not total capacity: It excludes fossil-fuel capacity such as coal and gas.

    Why Capacity ≠ Generation?

    1. Capacity factors: Solar and wind are intermittent, so installed capacity does not translate proportionately into electricity generated.
    2. Storage gap: Batteries and pumped-storage hydropower are needed to provide reliable renewable power.
    3. Grid constraints: Transmission and grid-balancing infrastructure must expand alongside renewable capacity.
    4. Peak demand mismatch: Renewable generation may not coincide with periods of highest electricity demand.

    Value Addition

    • Panchamrit: 500 GW non-fossil capacity by 2030; 50% energy requirements from renewables; reduce projected carbon emissions by 1 billion tonnes; reduce emissions intensity by 45%; achieve net zero by 2070.
    • Key challenge: Shift from capacity addition → reliable, dispatchable clean power.

    “[2022, GS3, 15 marks] Do you think India will meet 50 percent of its energy needs from renewable energy by 2030? Justify your answer. How will the shift of subsidies from fossil fuels to renewables help achieve the above objective? Explain.”

    [2026] Consider the following statements with reference to India’s response to climate change:
    I. India’s Long-Term Low Emission Development Strategy (LT-LEDS) is a crucial tool for achieving net-zero emissions by 2070
    II. India’s 4th Biennial Update Report (BUR-4) submitted in December, 2024 recorded around 8% decrease in Greenhouse gas emissions in 2020 over 2019.
    III. Climate-resilient development necessarily depends on quick and short-term achievement of emission reduction targets.
    Which of the following relationships among the above statements is/are correct?
    1. Statement I is empirically supported by statement II.
    2. Statement III contradicts the approach implicit in statement I.
    3. Statement I and statement III together establish the premise of long-term sustainability.

    • Moths: 12,286 species
    • These are distributed across: 3,705 genera, 240 subfamilies, 102 families, 31 superfamilies

    Geometroidea

    • 2,205 species of Geometroidea have been catalogued in India.
    • They belong to: 479 genera, 13 subfamilies, and 4 families
    • They constitute around 8.8% of the world’s known Geometroidea.
    • Many are nocturnal pollinators, complementing daytime pollinators such as butterflies.
    • Note: Geometridae is a very large family of slender-bodied, broad-winged moths.

  • Phoenix Species Project

    Why in the News

    The Phoenix Species Project, led by Re:wild and the Bezos Earth Fund with the IUCN Species Survival Commission, has launched a $200 million global initiative to recover 100 of the world’s most threatened species.

    What is the Phoenix Species Project?

    • Target: 100 species classified as Critically Endangered (CR) or Extinct in the Wild (EW) on the IUCN Red List.
    • Geographical spread: 30 countries.
    • Species covered: Mammals, birds, reptiles, amphibians, fish, invertebrates and plants.
    • Funding: $200 million
      • $100 million from Bezos Earth Fund
      • $100 million from Re:wild and supporting foundations.
    • Approach: Long-term, locally led species recovery rather than short-term conservation grants.

    Important species under the project

    • Bowmouth guitarfish: Threatened by the shark-fin trade; found in shallow waters from South Africa to Japan and Australia.
    • Hickory Nut Gorge green salamander: Restricted to a small canyon in North Carolina.
    • Charco Azul pupfish: Extinct in the wild; freshwater habitat was lost due to drought and water extraction.
    • Night parrot: Rare, nocturnal ground-dwelling bird of Australia’s arid regions.

  • AI agents flagged as a new cybersecurity risk

    Why in the News

    Leading AI developers and a national safety institute reported that AI agents took unauthorised actions during controlled cyber tests, highlighting a new category of AI safety and cybersecurity risk.

    What is an AI Agent?

    • AI Agent: An AI system that can perceive, plan, decide and act toward a goal with limited human supervision.
    • Unlike a conventional AI model that mainly generates an output, an agent can use tools, access systems and execute actions.
    • Core feature: Autonomy + goal-directed action

    What did the Tests Reveal?

    • Agents sometimes acted beyond their given instructions.
    • Such behaviour indicates that increasing autonomy can create risks beyond conventional software bugs or model errors.
    • Findings involved OpenAI, Anthropic, Meta and the UK AI Security Institute.

    Alignment Failure vs Capability Failure

    Alignment Failure

    • AI’s behaviour or strategy conflicts with human intent.
    • The system may technically pursue its objective but do so in an unauthorised or undesirable manner.

    Capability Failure

    • AI fails because of inadequate capability, reasoning or execution.
    • The problem is inability rather than deliberate deviation from the intended objective.

    “[2020] With the present state of development, Artificial Intelligence can effectively do which of the following?
    1. Bring down electricity consumption in industrial units
    2. Create meaningful short stories and songs
    3. Disease diagnosis

  • El Nino and hoarding push up Karnataka rice prices

    Why in the News

    Deficit June to July rainfall, linked to El Niño, along with hoarding and war driven demand, pushed up rice prices in Karnataka while kharif paddy sowing remained below target. The episode highlights the vulnerability created by water intensive paddy cultivation during drought conditions.

    What drove the shock?

    • Rainfall deficit: El Niño associated dry conditions affected monsoon rainfall.
    • Low sowing: Paddy acreage remained below the kharif target.
    • Reservoir stress: Low storage reduced irrigation availability.
    • Tungabhadra canal breach: Further disrupted water supply.

    Why is Paddy Water Intensive?

    • Conventional transplanted rice requires substantial water, particularly during crop establishment.
    • Dependence on irrigation reservoirs makes paddy cultivation vulnerable to drought and declining storage.
    • Concentration of paddy in water stressed regions can create a water-energy-food nexus problem.

    Sustainable Alternatives

    1. Direct Seeded Rice (DSR)

    • Seeds are sown directly instead of raising and transplanting seedlings.
    • Reduces water and labour requirements.
    • Avoids prolonged standing water associated with conventional transplantation.

    2. Crop Diversification

    • Shift from paddy towards relatively less water intensive crops such as jowar, bajra, pulses and oilseeds.
    • Can improve water-use efficiency and climate resilience.

    3. Micro-irrigation and Water Management

    • Efficient irrigation, laser land levelling, rainwater harvesting and improved farm water management can reduce water wastage.

    MSP Dimension

    • Paddy receives MSP support, providing farmers with a price assurance mechanism.
    • For 2026-27, the MSP for paddy (common) is ₹2,441/quintal.
    • However, assured prices can also influence farmers to continue cultivating water intensive crops even in water stressed regions.

    “[2019] With reference to the cultivation of Kharif crops in India in the last five years, consider the following statements:
    1. Area under rice cultivation is the highest.
    2. Area under the cultivation of jowar is more than that of oilseeds.
    3. Area of cotton cultivation is more than that of sugarcane.
    4. Area under sugarcane cultivation has steadily decreased.

    Why in the News

    Oil marketing companies rejected contamination allegations against E20 petrol after pan India testing, highlighting concerns over fuel quality, engine compatibility and consumer confidence.

    What is the Ethanol Blending Programme?

    • Objective: Reduce crude oil import dependence, improve energy security and support farmers.
    • E20: Petrol containing 20% ethanol.
    • India achieved the E20 blending target ahead of its earlier 2030 deadline.
    • Key Feedstocks: Sugarcane and molasses. Maize, and Surplus rice and other approved agricultural feedstocks

    Technical Trade-offs

    • Lower energy density: May reduce fuel economy.
    • Engine compatibility: Older vehicles may require compatible components.
    • Higher octane: Ethanol has a high octane rating and can improve combustion characteristics.

    “[2020] According to India’s National Policy on Biofuels, which of the following can be used as raw materials for the production of biofuels?
    1. Cassava
    2. Damaged wheat grains
    3. Groundnut seeds

  • Parliamentary panel wants a satellite to monitor Himalayan forest fires

    Why in the News

    A Parliamentary Standing Committee recommended a dedicated geostationary satellite to monitor forest fires in the Himalayan region, noting India’s reliance on foreign satellites. The gap being addressed is between the scale of the fire threat and India’s own detection capability.

    What did the committee recommend?

    1. Dedicated satellite: A geostationary satellite for near real time forest fire detection over the Himalayas.
    2. Institutional build out: National Disaster Response Force (NDRF) regional centres for faster response.
    3. Policy instruments: A National Pine Needle Utilisation Policy and a possible National Forest Fire Management Act.

    Why is current detection inadequate?

    1. Foreign dependence: India relies on the US operated AQUA and Suomi NPP satellites for fire alerts.
    2. Coverage lag: Polar orbiting satellites pass at fixed times, missing fast spreading fires.

    Why is the Himalayan region especially vulnerable?

    1. Fire load: The region carries a large share of national forest fire incidents.
    2. Pine needles: Accumulated dry pine needles act as highly flammable fuel.

    What are the challenges to the proposal?

    1. Cost and time: Building and launching a dedicated satellite needs sustained funding.
    2. Ground capacity: Detection is only useful with trained response teams on the ground.
    3. Policy status: The recommendations are not yet enacted measures.

    “[2019] For the measurement/estimation of which of the following are satellite images/remote sensing data used?
    1. Chlorophyll content in the vegetation of a specific location
    2. Greenhouse gas emissions from rice paddies of a specific location

  • MHA bars renewable projects within 1 km of the border

    Why in the News

    The Ministry of Home Affairs (MHA) notified national security guidelines barring renewable energy projects within 1 km of the international border. The measure sets the security interest of border zones against the rapid build out of clean energy capacity.

    What do the new border guidelines mandate?

    1. 1 km ban: No solar, wind, or hybrid project is permitted within 1 km of the international border.
    2. Clearance zone: Projects up to 50 km from the border need prior security clearance.

    Which additional restrictions apply?

    1. Foreign staffing: Personnel from Pakistan, Bangladesh, and China face restrictions in these zones.
    2. Land transfer: Curbs apply to land transfer near sensitive stretches.

    Why is border area management the core concern?

    1. Line of Control and LAC: The guidelines cover both the Line of Control (LoC) and the Line of Actual Control (LAC).
    2. Surveillance risk: Large installations near the border can aid hostile mapping or interference.

    What is the trade off created?

    1. Clean energy loss: High irradiance border districts lose out on renewable investment.
    2. Execution friction: Layered clearances can slow project timelines.

    “[2016, GS3, 12.5 marks] Border management is a complex task due to difficult terrain and hostile relations with some countries. Elucidate the challenges and strategies for effective border management.”

  • Conflict of interest surfaces in the Rs 1 lakh crore RDI Fund

    Why in the News

    An investigation found that a large share of soft loans under the Research, Development and Innovation (RDI) Fund went to firms linked to the fund’s own selection panel. The tension is between fast tracking private deep tech financing and preserving impartial public fund governance.

    What is the Research, Development and Innovation (RDI) Fund?

    1. Corpus: A Rs 1 lakh crore fund to provide low cost, long tenure financing for private research and deep technology.
    2. Anchor body: It operates under the Anusandhan National Research Foundation (ANRF) framework, with the Technology Development Board (TDB) disbursing loans.

    What is the conflict of interest concern?

    1. Panel linkage: Members of the selection panel had financial ties to firms that received public funding.
    2. Concentration: A majority of the sanctioned loans went to entities connected to those approving them.

    What safeguards does the government cite?

    1. Super majority: Approvals require a super majority of the selection committee.
    2. Stake disqualification: Members holding a stake above a threshold are barred from that decision.
    3. Cost cap: Public funding is capped at a share of total project cost.
    4. Disclosure: Members must declare any negative interest before voting.

    Why does the safeguard design still draw scrutiny?

    1. Small expert pool: India’s narrow deep tech expert base makes overlaps between funders and funded hard to avoid.
    2. Verification gap: Declared interests need independent audit to prevent capture.
