    What are Strategic Petroleum Reserves (SPR)?

    Why in the News?

    India is planning to establish six new Strategic Petroleum Reserve (SPR) sites to boost energy security amid rising global oil risks.

    About Strategic Petroleum Reserves (SPR):

    • Overview: SPRs are emergency stockpiles of crude oil maintained by the government to manage supply disruptions caused by events like wars, embargoes, or price shocks.
    • Purpose: To ensure national energy security and reduce vulnerability to external supply shocks.
    • Historical Context: India realised the need for SPRs after the 1990 Gulf War, which caused supply cuts and spiking oil prices and ultimately the Balance of Payment (BoP) Crisis.
    • Foundation: The SPR project began in the early 2000s based on advice from the Planning Commission’s Integrated Energy Policy.
    • Governing Body: In 2004, the government set up Indian Strategic Petroleum Reserves Limited (ISPRL) as a Special Purpose Vehicle under the Oil Industry Development Board (OIDB).
    • India’s three-pronged oil security framework:
      1. Commercial oil stocks by public and private oil marketing companies (OMCs).
      2. Strategic reserves by ISPRL for emergencies.
      3. Equity oil assets abroad through companies like ONGC Videsh Ltd. (OVL).
    • Storage: Unlike commercial stocks, SPRs are stored in underground rock caverns, which are safer, more secure, and suited for long-term preservation.

    Current SPR Infrastructure:

    • SPR Locations: India has three active SPR sites:
      • Visakhapatnam (Andhra Pradesh)
      • Mangaluru (Karnataka)
      • Padur (Karnataka)
    • Total Capacity: The combined SPR capacity is 5.33 MMT or roughly 39 million barrels.
    • Coverage Duration: This reserve can meet about 9.5 days of India’s daily oil requirement (≈5.5 million barrels/day).
    • Distinction from OMC Stocks: These strategic stocks are separate from commercial stocks held by companies like IOCL, HPCL, and BPCL.

    Planned Expansion of SPRs in India:

    • Goal: India aims to double SPR capacity due to rising geopolitical risks and import dependence.
    • New Facilities Planned:
      • Chandikhol (Odisha) – 4 MMT (in two phases)
      • Padur Phase II (Karnataka) – 2.5 MMT
    • 6 new SPR locations are being planned at various sites, including Mangalore SEZ (Karnataka) and salt caverns in Bikaner (Rajasthan).
    • Future Capacity: After expansion, India’s total SPR stock will be 11.83 MMT, covering around 22 days of national demand.
    • Strategic Vision: The long-term objective is to build up 90 days of oil reserves, in line with International Energy Agency (IEA) guidelines.

    Climate Threat Emerging from Rising Evaporative Demand and Thirstwaves

    Why in the News?

    Scientists have coined a new term, “thirstwave”, to describe spikes in evaporative demand, where a warmer atmosphere draws more water from plants, soil, and trees.

    What is Evaporative Demand?

    • Definition: Evaporative demand is the measure of how much water the atmosphere can potentially absorb from land, plants, and water surfaces if there is unlimited water available. It tells us how “thirsty” the atmosphere is.
    • Nature of Measurement: It is not about how much water is actually lost but how much could be lost if water was fully available. It depends on weather conditions, not the amount of water in the soil.
    • Standard Metric: The most widely used metric to quantify this is Standardized Short-Crop Reference Evapotranspiration (ETos)—which assumes a 12 cm grass surface with unlimited water availability.
    • Impact of Global Warming: As global warming increases atmospheric heat, evaporative demand also rises, making the air more “thirsty”.

    What is a Thirstwave?

    • Origin: “Thirstwave” is a newly coined term (2025) by Meetpal Kukal and Mike Hobbins to describe three or more consecutive days of extreme evaporative demand.
    • Definition: A thirstwave is a period of sudden and intense increase in evaporative demand, caused by hot, dry, and sunny weather. It means the atmosphere becomes extremely “thirsty” and starts pulling water rapidly from soil, plants, and water bodies, even if they already have limited moisture.
    • Distinction from Heatwaves: Unlike heatwaves, thirstwaves account for multifactorial stress, combining temperature, humidity, wind, and solar input.
    • Thirstwave in India: There is no dedicated data yet on thirstwaves in India, but researchers are beginning to investigate, especially in South Asia’s climate-vulnerable zones.

    Rising Evaporative Demand and Thirstwaves

    Why in the News?

    Scientists have coined a new term, “thirstwave”, to describe spikes in evaporative demand, where a warmer atmosphere draws more water from plants, soil, and trees.

    What is Evaporative Demand?

    • Definition: Evaporative demand is the measure of how much water the atmosphere can potentially absorb from land, plants, and water surfaces if there is unlimited water available. It tells us how “thirsty” the atmosphere is.
    • Nature of Measurement: It is not about how much water is actually lost but how much could be lost if water was fully available. It depends on weather conditions, not the amount of water in the soil.
    • Standard Metric: The most widely used metric to quantify this is Standardized Short-Crop Reference Evapotranspiration (ETos)—which assumes a 12 cm grass surface with unlimited water availability.
    • Impact of Global Warming: As global warming increases atmospheric heat, evaporative demand also rises, making the air more “thirsty”.
    • Key Features:
      • Simplified Model: ETos simplifies evapotranspiration by assuming fixed vegetation properties and only variable weather conditions.
      • Indicators of Stress: An increase in ETos indicates higher temperatures, lower humidity, faster wind, and stronger solar radiation.
      • Effect on Soil and Crops: Rising evaporative demand leads to more rapid drying of soil and plants, even with ample irrigation.
      • Agricultural Relevance: This directly affects irrigation scheduling, crop productivity, and climate-resilient farming strategies.

    What is a Thirstwave?

    • Origin: “Thirstwave” is a newly coined term (2025) by Meetpal Kukal and Mike Hobbins to describe three or more consecutive days of extreme evaporative demand.
    • Definition: A thirstwave is a period of sudden and intense increase in evaporative demand, caused by hot, dry, and sunny weather. It means the atmosphere becomes extremely “thirsty” and starts pulling water rapidly from soil, plants, and water bodies, even if they already have limited moisture.
    • Distinction from Heatwaves: Unlike heatwaves, thirstwaves account for multifactorial stress, combining temperature, humidity, wind, and solar input.
    • Thirstwave in India: There is no dedicated data yet on thirstwaves in India, but researchers are beginning to investigate, especially in South Asia’s climate-vulnerable zones.

  • 50 Years of National Emergency

    Why in the News?

    On June 26, 2025, India marks the 50th anniversary of the Emergency, imposed in 1975 by then Prime Minister Indira Gandhi.

    What is National Emergency? (Article 352)

    • Definition: A national emergency is a constitutional provision under Article 352 of the Indian Constitution.
    • Grounds for Proclamation: It can be proclaimed by the President of India when the security of India or any part of it is threatened by:
      • War
      • External Aggression
      • Armed Rebellion
      • (Earlier also included “internal disturbance”, removed via the 44th Amendment, 1978)

    Grounds of Proclamation: Evolution

    • Original Provision (1950): Allowed Emergency for “internal disturbance”, which was vague and broad.
    • 38th Amendment Act (1975): Made the President’s satisfaction final and beyond judicial scrutiny.
    • 44th Amendment Act (1978):
      • Replaced “internal disturbance” with “armed rebellion” to curb misuse.
      • Restored judicial review of the President’s decision.

    Process of Proclamation

    • Initiation: The Union Cabinet (not just the PM) must send a written recommendation to the President.
    • Anticipatory Power: The proclamation can be issued before the actual occurrence of war, aggression, or rebellion.
    • Parliamentary Approval:
      • Must be ratified by both Houses within 1 month.
      • Requires a special majority:
        • Majority of the total membership.
        • Two-thirds of members present and voting.
      • Valid for 6 months; can be extended indefinitely with fresh approvals every 6 months.

    Territorial Application

    • Original Scope: Applied to the entire nation.
    • 42nd Amendment Act (1976): Permitted partial emergencies limited to specific states or territories.

    Judicial Review:

    • Before 1975: Emergency proclamations could be challenged in courts.
    • After the 38th Amendment: Made proclamations immune to judicial review.
    • Post-44th Amendment: Judicial review restored.
    • Minerva Mills Case (1980): SC ruled that Emergency can be struck down if based on mala fide, irrelevant, or absurd grounds.

    Revocation of National Emergency:

    • Duration: Can continue indefinitely with periodic 6-month renewals.
    • Revocation: The President can revoke anytime without Parliamentary approval.
    • Lok Sabha Oversight:
      • If 1/10th of Lok Sabha members give written notice, the Speaker/President must convene a session within 14 days.
      • Disapproval motion can pass with a simple majority.

    Historical Precedents:

    India has witnessed 3 National Emergencies:

    • 1962–1968: Due to war with China (external aggression).

      • Under Article 83(2), its term can be extended by one year at a time.
      • Cannot continue beyond 6 months after Emergency ends.
    • State Assemblies: Term can be similarly extended with the same limitation.
    1. Fundamental Rights:
    • Article 358 – Automatic Suspension:
      • Article 19 is automatically suspended, only when Emergency is due to war or external aggression.
      • Applies nationwide, regardless of where Emergency is declared.
    • Article 359 – Presidential Order:
      • President can suspend court enforcement of specified Fundamental Rights.
      • Does not apply to Articles 20 and 21.
