{GS1 – Geo – EG – Water Resources} Inefficient Agriculture Water Use in India

• Context (IE): India needs to reimagine its agricultural water use to achieve food security.

Agriculture Water Use in India

• India has achieved remarkable agricultural success leading globally in milk and spice production and ranking 2^nd in fruits, vegetables, and fish. However, water use is inefficient and unsustainable.
• India is home to 18% of the world’s population; however, it holds just 4% of its freshwater. Agriculture consumes 78–90% of this limited resource, threatening long-term sustainability.

Extent of Water Use in Agriculture

• Groundwater Dependence: Around 65% of irrigated areas in India depend on groundwater.
• Over-Extraction: 78% of Punjab’s administrative blocks are now over-exploited, driven by the expansion of paddy cultivation and free electricity (Central Ground Water Board).
• Crop Mismatch: Water-intensive crops like paddy and sugarcane, grown in water-scarce regions, consume disproportionate resources.
• Alarming Groundwater Depletion: In Maharashtra, sugarcane grown on 4% of land consumes over 70% of irrigation water, impacting drought-prone areas like Solapur.

Reasons Behind Inefficient Water Use

• Inappropriate Cropping Patterns: Paddy in Punjab, Sugarcane in Maharashtra, and Wheat in Haryana are grown due to policy and subsidy distortions, not climatic suitability.
• Policy Distortions: Free electricity encourages excessive groundwater pumping without accountability.
• Policy Misalignment: Minimum Support Prices (MSPs) favor rice and wheat, discouraging farmers from shifting to less water-intensive crops like millets, pulses, and oilseeds.
  • The Green Revolution amplified these distortions, especially in northwestern India.
• Low Adoption of Micro-Irrigation: Of the 74 million hectares under irrigation, only about 12% uses efficient systems like drip or sprinkler irrigation.
• Weak Extension Services and Water Literacy: Many farmers are unaware of the long-term consequences of over-irrigation.

Food Security Despite high food production, India faces poor nutrition outcomes. The NFHS-5 reveals high levels of stunting (35.5%), underweight (32.1%) and undernourishment (16.6%), highlighting a disconnect between food security and nutritional security. This mismatch reflects incentives prioritise calorie-rich crops like rice and wheat, backed by water subsidies, at the cost of more nutritious, climate-resilient alternatives.

Initiatives for Efficient Water Management

• Pradhan Mantri Krishi Sinchayee Yojana (PMKSY): Aims to expand irrigation coverage and improve water use efficiency through components like AIBP, Watershed Development, and Per Drop More Crop.
• National Water Policy (2012): Promotes water conservation and the protection of water resources, emphasising rainwater harvesting.
• Atal Bhujal Yojana: Encourages community participation in sustainable groundwater management in water-stressed areas.
• Jal Shakti Abhiyan: A campaign-based initiative focusing on rainwater harvesting, water conservation, and rejuvenation of water bodies.
• PM-KUSUM Scheme: Promotes solar-powered irrigation pumps to reduce reliance on grid electricity and prevent groundwater over-extraction.
• National Mission for Sustainable Agriculture (NMSA): Supports climate-resilient farming with efficient water resource management.

State Level Interventions Jyotigram Yojana (Gujarat): Segregated power feeders for agriculture and domestic use, reducing groundwater exploitation. Jalyukt Shivar Abhiyan (Maharashtra): Aims to make villages drought-free by implementing decentralized water conservation techniques. Mission Kakatiya (Telangana): Focuses on restoring traditional tanks and water storage systems to improve irrigation.

Way Forward

• Two-Pronged Reform Strategy:
  1. Supply-Side Interventions:
     • Enhance water infrastructure and access in underutilized regions like eastern India.
     • Promote rainwater harvesting, watershed development, and surface water systems.
  2. Demand-Side Management:
     • Realign MSPs with ecological and nutritional needs.
     • Promote climate-smart crops like millets with sustained fiscal and procurement support.
     • Implement smart pricing of water and electricity to discourage overuse as seen in Andhra Pradesh’s pilot with prepaid meters.
     • Expand micro-irrigation: Currently at only 12% coverage, despite huge potential savings of 30–70% water.
     • Encourage public-private partnerships, equipment leasing, and targeted subsidies for small and marginal farmers.
• Smart Farming: IoT and sensor-based drip systems can boost water productivity significantly
• Community and Awareness: Local water user groups, audits, and rainwater harvesting schemes like Jalyukt Shivar and revived dams need supportive policy and funding
• Revival of Traditional Water Systems: Reviving traditional water management systems like Ahar Pynes (Bihar), Johads (Rajasthan), and Kudimaramath (Tamil Nadu) etc.

{GS3 – Envi – CC} Stratospheric Aerosol Injection

• Context (TH): Stratospheric Aerosol Injection is feasible, but global risks and ecological concerns remain.

What is Stratospheric Aerosol Injection (SAI)?

Source: The Hindu

• SAI is a solar geoengineering technique proposed to combat global warming by artificially cooling the Earth’s surface.
• Involves deliberate injection of reflective aerosols, such as sulphur dioxide (SO₂), into the stratosphere, where they reflect a portion of incoming solar radiation back into space.
• This technique mimics the natural cooling effect observed after major volcanic eruptions, offering a short-term strategy to offset rising temperatures caused by greenhouse gas emissions.
• Cooling Mechanism:
  • Chemical Conversion: Injected SO₂ reacts with water vapor in the stratosphere forming sulfuric acid aerosols (H₂SO₄). These aerosols do not fall quickly and linger for months to years.
  • Radiative Forcing Reduction: The aerosols increase Earth’s albedo (measure of solar energy reflected by Earth). Enhanced albedo leads to reduced solar radiation reaching the Earth’s surface.

Aerosols, tiny suspended particles, whether natural (like volcanic ash) or anthropogenic (like industrial soot), can alter the Earth’s radiation balance. The stratosphere, the stable atmospheric layer above the troposphere (~10–50 km altitude), contains the ozone layer and can host aerosols for longer durations. Geoengineering refers to large-scale, deliberate climate interventions, mainly categorized as Carbon Dioxide Removal (CDR) and Solar Radiation Management (SRM).

Significance

• Climate Cooling Potential: Injecting 12 million tonnes of SO₂ annually at 13 km altitude could cool Earth by ~0.6°C; 21 million tonnes needed for 1°C cooling (2025 study).
• Aerosol Behaviour: Higher-altitude aerosols stay longer (months to years), enhancing cooling, especially near the equator where the stratosphere is higher.

Challenges

• Environmental Risks: May disrupt monsoon patterns, hydrological cycles, delay ozone recovery (increasing UV and acid rain), and mask global warming, reducing urgency for emission cuts.
• Unequal Climate Effects: More cooling in polar regions than tropics, raising fairness concerns.
• Global Governance Challenges: Aerosol injection affects all nations, creating geopolitical risks amid lacking global regulation.
• Scientific Uncertainties: Cooling requires continuous injection—sudden stop risks rapid warming (“termination shock”).

{Prelims – Sci – Bio} Bacteriophages

• Context (TH): Bacteriophages are re-emerging as alternatives to antibiotics.

• Bacteriophages are viruses that infect and destroy specific bacteria, hence called “good viruses.” Structurally, it consists of nucleic acid (DNA or RNA; single- or double-stranded) enclosed in a protein shell.
• Found widely in nature—soil, water, and the human microbiome.
• Key Characteristics:
  • High specificity: Infect only select bacterial strains, preserving beneficial microbiota—unlike broad-spectrum antibiotics.
  • Self-limiting action: Multiply only in the presence of their target bacteria and degrade once the infection is cleared, reducing overdose risk.
  • Evolutionary adaptability: Capable of co-evolving with bacteria, allowing them to overcome bacterial resistance—a dynamic feature absent in conventional drugs.
• Therapeutic Strategies:
  • Natural Phage Therapy: The infecting bacteria are isolated and tested against a phage library.
    • The effective phage is then cultured and administered to the patient.
    • Phages are sourced from domestic or international phage banks.
  • Genetically Engineered Phages: Modified in labs to expand host range, enhance effectiveness, or target dormant bacteria.
    • They may carry enzymes to break biofilms or bypass bacterial defence mechanisms.

• Uses: Used in treating burns and diabetic foot ulcers, urinary tract infections, respiratory tract and gastrointestinal infections, and Multi-drug resistant (MDR) bacterial infections where antibiotics fail.
• Limitations: Each phage is specific to a particular bacterial strain; therefore, treatment requires matching and personalisation.
