  • GS-1: Society – Child health protection, Public awareness on correct ORS usage.
  • GS-4: Ethics – Ethical responsibility in medical communication and product labelling.

Understanding ORS

  • Definition: Oral Rehydration Solution (ORS) is a medical solution containing precise ratios of glucose, sodium chloride, and potassium chloride.
  • Purpose: Rehydrates patients by facilitating water absorption in the gut; prevents death from diarrhoea.
  • Global significance: ORS is a landmark medical discovery by Dr Dilip Mahalanabis, saving millions of lives worldwide.
  • Child mortality context in India:
    • 13% of deaths in children under five are due to diarrhoea.
    • Improper ORS use or substitutes can worsen dehydration and diarrhoea.

Problem with Flavoured/Packaged ‘ORS’ Products

  • Entered market over the last decade without adhering to correct sugar-salt ratios.
  • Excess sugar can draw water out of the gut, worsening diarrhoea.
  • Even with disclaimers, branding misleads caregivers, leading to critical dehydration.
  • Case examples:
    • Children in Hyderabad and Madhya Pradesh became critically ill after consuming such beverages.

Regulatory Journey

  • Initial confusion: ORS products are medical; assumed regulated by CDSCO (drug regulator).
  • Correct authority: FSSAI (food regulator).
  • Timeline:
    • April 2022: FSSAI restricted ORS use with some limitations.
    • Later reversed to allow ORS in names with disclaimers.
    • October 2025: FSSAI finally bans use of ORS in beverage names.
  • Advocacy:
    • Dr Santhosh approached Telangana High CourtHealth MinisterPrime Minister, and medical associations.
    • Faced opposition from industry and social isolation.

Health & Scientific Significance

  • ORS works by osmosis: glucose and electrolytes pull water into the body, rehydrating effectively.
  • Improper substitutes can:
    • Increase severity of diarrhoea.
    • Cause hospitalisations and deaths.
  • Highlights the importance of correct labelling and public awareness of medical products.

Key Facts & Data

  • ORS prevents 13% of under-five deaths from diarrhoea in India.
  • Misbranded ORS-like drinks caused critical dehydration and hospitalisations.
  • Advocacy duration: 8 years by Dr Sivarangini Santhosh.
  • Regulatory outcome: FSSAI bans the term ‘ORS’ in beverage names.
  • Scientific fact: Proper ORS contains fixed glucose, sodium chloride, potassium chloride ratios; deviations can worsen dehydration.

  • GS-2: Governance – International climate governance, Policy responses, Multilateral coordination (UNFCCC, WMO).
  • GS-1: Society – Impact on livelihoods, Migration, and human security.

Understanding CO2 and Greenhouse Gases ?

  • CO2 as a greenhouse gas (GHG):
    • Primary driver of climate change, contributing ~66% of global warming since pre-industrial times.
    • Sources:
      • Natural: respiration, decomposition, wildfires, ocean releases, volcanic eruptions.
      • Anthropogenic: fossil fuel burning, industry, land-use change.
    • Natural sinks (forests, oceans) absorb roughly half of human CO2 emissions.
  • Other GHGs:
    • Methane (CH4): 16% of warming; increased to 1,942 ppb in 2024. Lifetime ~12 years.
    • Nitrous oxide (N2O): 6% of warming; increased to 338 ppb in 2024. Lifetime 100–120 years.

Trends and Record Increase

  • Long-term trend: CO2 has never declined in last 40 years; annual average increase: 0.8 ppm/year since 1957.
  • Acceleration:
    • 1960s: 0.8 ppm/year.
    • 2011–2020: 2.4 ppm/year.
    • 2023–2024: record jump of 3.5 ppm/year, unprecedented.
  • Relative to pre-industrial levels (278.3 ppm): Current CO2 152% higher.

Causes Behind Record Rise

  • Anthropogenic emissions: Continued fossil fuel burning.
  • Natural feedbacks reducing CO2 absorption:
    • Oceans: reduced solubility due to higher temperatures.
    • Forests and land sinks: extreme droughts, wildfires, deforestation reduced CO2 uptake.
  • Exceptional events: Large-scale forest fires in 2024 added extra emissions.
  • Feedback loops: Higher temperatures → less CO2 absorption → more warming → more emissions.

Global Temperature Context

  • 2024: Warmest year recorded, 1.55°C above pre-industrial levels.
  • Significance: Breaching 1.5°C threshold increases risks of:
    • Irreversible climate impacts (sea-level rise, ice melt).
    • Extreme weather events (heatwaves, floods, droughts).
  • GHG contribution:
    • CO2: ~75% of warming in last decade.
    • CH4: shorter-term impact but potent GHG.
    • N2O: long-term atmospheric persistence.

Implications and Challenges

  • Rapid CO2 accumulation signals failure to slow emissions meaningfully despite global efforts.
  • Climate feedbacks exacerbate warming: higher CO2 → reduced absorption → higher temperatures → more CO2 release.
  • Urgency for action: Need enhanced mitigation, renewable energy adoption, forest protection, and global cooperation.

  • GS-2: Governance – Water security policy, Spring revival initiatives, Climate-resilient local governance.
  • GS-3: Environment – Hydrology, Deforestation, Ecosystem services, Agriculture dependency.

Understanding Himalayan Springs ?

  • Definition: Springs are natural groundwater outlets, providing freshwater for drinking, irrigation, and livestock.
  • Significance:
    • Source of water for 200 million people across ecologically fragile mountain systems in India (Himalayas, Western/Eastern Ghats, Aravallis).
    • Sustain agriculture, livestock, and local livelihoods.
    • Cultural and social importance; tied to traditional practices and local knowledge.
  • Historical self-reliance: Villages like Kolbong Khasmahal were once self-sufficient in vegetables and milk, relying on local water sources.

Causes of Drying Springs

  • Climate shifts: Changing rainfall patterns, unpredictable monsoons, and prolonged dry periods.
  • Deforestation & unsustainable land-use: Reduced soil water retention, increased runoff, and diminished aquifer recharge.
  • Anthropogenic neglect: Limited recognition in national water governance frameworks prior to 2018; National Water Policies of 1987, 2002, 2012 made no mention of springs.
  • Local impacts: Excessive withdrawal, lack of spring recharge practices, and encroachment.

Socio-Economic Impacts

  • Water access burden on women:
    • Average of 2 hours/day spent fetching water from distant springs.
    • Physical strain, health risks, and impact on household management.
  • Livelihood loss:
    • Decline in local vegetable production and dairy products like churpi.
    • Dependence on imported vegetables and packaged milk from towns like Dhupguri and Maynaguri.
  • Migration: Youth move to cities due to declining local economic opportunities.
  • Pandemic effect: Returning migrants found parched lands and dry springs, compounding livelihood challenges.

Environmental and Ecological Implications

  • Water stress: Springs drying → reduced soil moisture → declining crop productivity.
  • Forest degradation: Feedback loop with deforestation and drought further reduces natural recharge of springs.
  • Biodiversity: Reduced water availability affects flora, fauna, and livestock dependent on spring-fed ecosystems.
  • Ecological crisis: Combined hydrological, agricultural, and biodiversity loss threatens the Himalayan ecosystem.

Policy & Governance Context

  • NITI Aayog 2018 Report: First formal acknowledgment of spring degradation; launched Inventory and Revival of Springs for Water Security in the Himalayas.
  • Gap in policy: Prior national water policies ignored mountain spring systems, reflecting institutional neglect.
  • Regional water governance: Ongoing initiatives by SaciWATERs and IUCN India focus on climate resilience, water management, and revival of springs.

Cultural and Human Security Implications

  • Springs are intertwined with traditions, local knowledge, and community identity.
  • Drying springs are a non-traditional security threat:
    • Threat to livelihoods and food security.
    • Gendered burden on women’s labor and time.
    • Potential migration and social disruption.
