  • [16th March 2026] The Hindu OpED: Building India’s climate resilience with water at the core

    PYQ Relevance[UPSC 2017] Climate Change is a global problem. How India will be affected by climate change? How Himalayan and coastal states of India will be affected by climate change?Linkage: Climate change in India largely manifests through water stress, floods, glacial melt, and sea-level rise. The article links these impacts to Himalayan river instability and coastal aquifer salinisation, highlighting regional climate vulnerability.

    Why in the News?

    The COP30 Climate Summit in Belém (Brazil, 2025) introduced the first global adaptation indicators integrating Water, Sanitation and Hygiene (WASH) systems into climate accountability frameworks. Now there is a major shift in global climate governance: water systems are emerging as the central pillar of climate resilience. The outcomes of the UN Climate Conference COP30 and the Belém Adaptation Indicators place water management, sanitation, and hydrological governance at the core of adaptation strategies.

    How does climate change manifest primarily through water systems in India?

    1. Hydrological Disruptions: Climate change alters rainfall patterns, leading to extreme floods and prolonged droughts affecting urban and rural economies.
    2. Glacial Melt Impact: Himalayan glacier retreat destabilizes river systems, affecting long-term water availability for major rivers like the Ganga and Brahmaputra.
    3. Saline Intrusion: Rising sea levels cause salinisation of coastal aquifers, contaminating freshwater sources in coastal regions.
    4. Agricultural Vulnerability: Agriculture contributes ~40% of anthropogenic methane emissions, particularly from rice cultivation, livestock systems, and organic waste.
    5. Food Security Threats: Erratic monsoon cycles disrupt crop productivity and irrigation systems.

    What are Belém Adaptation Indicators?

    1. The Belém Adaptation Indicators are a set of 59-60 voluntary, global measures adopted at the COP30 climate summit in Belém, Brazil (scheduled for November 2025) to track how well countries are adapting to climate change. 
    2. Developed through a two-year UN process under the UAE-Belém Work Programme, they aim to provide a shared, practical language for monitoring resilience against climate impacts like floods, droughts, and heatwaves.

    Key Features of the Belém Adaptation Indicators are as follows:

    1. Purpose: To monitor progress toward the Global Goal on Adaptation (GGA) adopted under the Paris Agreement, focusing on whether communities are becoming safer and better able to cope with climate threats
    2. Focus Areas: The measures look at essential sectors such as water security, food systems, health, housing, early warning systems, ecosystems, and local economies
    3. Scope: The indicators emphasize protecting vulnerable populations, including women, indigenous groups, and people with disabilities
    4. Voluntary Nature: They are designed to be flexible rather than a rigid top-down mandate, allowing countries to adapt them to their national circumstances.

    How do Belém Adaptation Indicators redefine climate governance?

    1. Climate-Resilient Water Systems: Focus on reducing water scarcity and increasing resilience against floods and droughts.
    2. Universal Drinking Water Access: Ensures safe drinking water availability for all communities.
    3. Climate-Resilient Sanitation Infrastructure: Strengthens sanitation systems capable of functioning during extreme climate events.
    4. Multi-Hazard Early Warning Systems: Establishes universal early warning coverage by 2027.
    5. Hydrometeorological Capacity: Strengthens meteorological monitoring and national vulnerability assessments by 2030.

    How is India strengthening water governance to build climate resilience?

    1. Institutional Consolidation: Establishment of the Ministry of Jal Shakti (2019) integrates water governance across sectors.
    2. Water Vision 2047: Aligns national water policy with sustainability, equity, and climate resilience goals.
    3. Aquifer Mapping Programme: National Aquifer Mapping and Management Programme (NAQUIM 2.0) advances aquifer-level planning based on hydrogeological data.
    4. River Rejuvenation: National Mission for Clean Ganga (NMCG) expands focus beyond sewage treatment to biodiversity restoration and river basin management.
    5. Integrated Water Management: Encourages linking scientific hydrology with policy planning.

    What systemic risks threaten India’s climate-water resilience?

    1. Unequal Water Distribution: Water scarcity remains acute and unevenly distributed across regions.
    2. Water-Linked Disasters: Most climate disasters in India are water-related (floods, droughts, cyclones).
    3. Fragile Adaptation Finance: Global climate finance pathways remain uncertain despite projections of $1.3 trillion annually by 2035.
    4. Recovery Bias: Lack of predictable finance shifts focus toward post-disaster recovery rather than long-term resilience planning.
    5. Infrastructure Stress: Water supply systems require climate stress testing and diversification of water sources.

    Why is digital fragmentation a challenge for climate-water governance?

    1. Fragmented Data Systems: Hydrological and meteorological datasets remain distributed across institutions without integration.
    2. Limited AI-Driven Decision Support: Despite large datasets, real-time AI integration in governance remains weak.
    3. Planning Disconnect: Water data is rarely linked to budgeting, crop advisories, insurance mechanisms, or disaster response systems.
    4. Need for Interoperable Platforms: Integration of hydrological data, crop advisory systems, insurance frameworks, and financial flows is essential.

    How can India lead global climate adaptation through water governance?

    1. Policy Convergence: Align national missions such as drinking water coverage, irrigation efficiency, and urban water reforms with climate adaptation.
    2. Digital Public Infrastructure: Utilize India’s strength in digital governance systems to integrate climate-water datasets.
    3. Operational Adaptation: Shift from infrastructure creation to functional system resilience.
    4. Global South Leadership: Demonstrate scalable climate adaptation models applicable to other developing countries.

    Conclusion

    Water systems are emerging as the operational backbone of climate adaptation. India possesses strong institutional foundations, including water governance reforms, digital infrastructure, and river restoration programmes. However, translating policy ambition into measurable climate resilience requires integrating hydrological data, strengthening climate finance, and ensuring equitable water distribution. By aligning national missions with global adaptation frameworks, India can emerge as a leader in climate-resilient water governance for the Global South.

  • Ice patches on melting glaciers greater threat than thought: ISRO scientists

    Why in the News

    A new study by scientists from the Indian Space Research Organisation has identified exposed ice patches on retreating Himalayan glaciers as a key precursor to flash floods. The study examined the August 5, 2025 Dharali flash flood in Uttarakhand that killed nine people and devastated settlements along the Bhagirathi river valley. Satellite imagery revealed exposed ice patches in the nivation zone of the Srikanta glacier shortly before the disaster. (Nivation is defined as the erosion of the ground beneath and around a snow bank, primarily resulting from the processes of alternate freezing and thawing.) This indicates accelerated deglaciation and unstable cryosphere conditions. This finding marks an important shift in understanding Himalayan hazards: disasters may originate not only from glacial lake outburst floods (GLOFs) but also from smaller, previously overlooked cryospheric instabilities linked to warming temperatures.

    What are exposed ice patches?

    1. Exposed ice patches are areas of ancient, stable ice that have become visible on the surface of a glacier or mountain slope after their protective covering of seasonal snow and firn (intermediate ice) has thinned or melted away. 
    2. Unlike the main body of a glacier, which flows like a slow-moving river, these patches are often stationary and act as “prehistoric freezers”

    Reasons for their formation are as follows:

    1. Thinning Insulation: Warmer temperatures reduce the layers of snow and firn that normally insulate the deeper ice.
    2. Ablation: During the ablation period (when a glacier loses more ice/snow than it gains), these patches may emerge on steep, shaded slopes, particularly in nivation hollows where snow traditionally lingers year-round.
    3. Wind Scouring: In some regions, like Antarctica, strong winds can strip away top layers to reveal bright blue patches of older, denser ice.

    How do exposed ice patches signal accelerated glacier retreat in the Himalayas?

    1. Deglaciation indicator: Exposed ice patches in the Srikanta glacier’s ablation zone indicate thinning seasonal snow and firn cover due to rising temperatures.
    2. Satellite evidence: Pre-event satellite imagery showed persistent exposed ice patches on north-northeast facing slopes where snow normally accumulates.
    3. Cryosphere instability: Loss of insulating snow layers accelerates melting and structural weakening of glaciers.
    4. Regional warming effect: Similar processes have been documented in other warming cryosphere regions including the Canadian Arctic and Greenland.

    What role did nivation processes play in triggering the Dharali flash flood?

    1. Nivation process: Erosion of ground beneath snowbanks caused by alternate freezing and thawing cycles.
    2. Formation of nivation hollows: Repeated snow accumulation creates depressions which deepen over time.
    3. Structural instability: In steep Himalayan terrain, nivation hollows accumulate ice, meltwater, and debris.
    4. Trigger mechanism: Collapse of an exposed ice patch within the nivation zone of the Srikanta glacier released meltwater and debris.
    5. Result: Sudden downstream debris flow triggered the Dharali flash flood.

    Why are Himalayan glaciers increasingly vulnerable to cryosphere hazards?

    1. Rapid glacier retreat: Himalayan glaciers are losing ice due to rising regional temperatures.
    2. Snow and firn thinning: Seasonal snow cover that stabilizes glaciers is shrinking.
    3. Steep mountain terrain: High relief areas amplify instability and debris flow risks.
    4. Glacier fragmentation: Smaller unstable ice masses form as glaciers shrink.
    5. Emerging hazard types: Hazards now include not only GLOFs but also ice collapses, debris flows, and cryosphere mass movements.

    How do satellite observations improve early warning systems for glacier disasters?

    1. Pre-event detection: Satellite imagery identified exposed ice patches before the Dharali flood.
    2. Landscape monitoring: Remote sensing helps track glacier retreat and unstable cryosphere zones.
    3. Hazard reconstruction: Earth observation data reconstructs sequences leading to disasters.
    4. Early warning potential: Monitoring exposed ice patches could provide advance signals of possible cryosphere hazards.

    Why must disaster monitoring extend beyond glacial lakes to smaller cryosphere instabilities?

    1. Focus shift: Traditional monitoring emphasizes glacial lake outburst floods.
    2. Overlooked hazards: Small-scale cryosphere instabilities can trigger similar destructive floods.
    3. Regional prevalence: Similar geomorphological conditions exist across much of the Himalayan arc.
    4. Policy implication: Disaster risk assessment must include nivation zones and exposed ice patches.

    Conclusion

    Rapid glacier retreat in the Himalayas is generating new cryosphere hazards beyond traditional glacial lake outburst floods. The Dharali flash flood demonstrates how exposed ice patches and nivation-zone instability can trigger sudden disasters in high-mountain regions. Strengthening satellite monitoring, hazard mapping, and climate-resilient disaster management systems is essential to reduce risks and protect vulnerable Himalayan communities.

  • Electrifying industrial heat as a path for thermal independence

    Why in the News?

    Rising tensions in West Asia, particularly around the Strait of Hormuz, have raised concerns about disruptions in global natural gas supplies. Since India imports nearly half of its natural gas, recent supply cuts have reduced gas allocation to industries to about 65-80% of contracted volumes, affecting manufacturing clusters such as Morbi (ceramics) and Ludhiana (textiles) that depend heavily on gas-based industrial heat. The situation has revived discussions on reducing industrial dependence on imported fuels for heat generation and moving toward electrified heat systems and concentrated solar thermal (CST) to achieve greater thermal independence and energy security.

    What is Industrial Heat?

    1. Industrial heat refers to the thermal energy required for manufacturing processes like melting, drying, and refining, accounting for ~74% of industrial energy demand.
    2. Primarily generated by burning fossil fuels, this sector contributes ~18% of global greenhouse gases. Transitioning to electrification, green hydrogen, and thermal storage is crucial for decarbonization.

    Key Aspects of Industrial Heat:

    1. Temperature Ranges:
      1. Low (<150°C): Food/beverage, paper/pulp (drying, pasteurization)
      2. Medium (150-400°C): Chemical separation, refining
      3. High (>400°C): Steel (up to 1,600°C), cement (1,400-1,500°C), glass.
    2. Primary Sources: Mostly natural gas, coal, and oil.
    3. Common Applications: Process heat is used for steam production, drying, calcining, and smelting.

    Why Does Industrial Heat Represent a Strategic Energy Challenge for India?

    1. Industrial Energy Demand: Industrial heat accounts for nearly 25% of India’s total energy consumption, making it a major driver of fossil-fuel demand.
    2. Fossil Fuel Dependence: Manufacturing sectors rely heavily on coal, natural gas, and LPG to produce process heat.
    3. Geopolitical Vulnerability: Heavy dependence on imported natural gas exposes India to global supply disruptions and price volatility.
    4. Industrial Clusters: Manufacturing hubs such as Morbi (ceramics) and Ludhiana (textiles) rely on gas-based boilers for steam generation.
    5. High Temperature Requirements: Industrial processes often require temperatures exceeding 1000°C, limiting easy substitution with conventional renewable electricity.

    How Does Electrification of Industrial Heat Improve Efficiency and Sustainability?

    1. Electromagnetic Heating: Electric heating technologies generate heat using electromagnetic fields and plasma, improving energy conversion efficiency.
    2. Higher Efficiency Levels: Electric heating systems achieve efficiency levels exceeding 90%, significantly higher than fossil-fuel boilers.
    3. Reduced Heat Loss: Conventional gas boilers lose 20-30% of energy through exhaust gases, reducing system efficiency.
    4. Direct Heat Generation: Technologies such as induction heating transfer heat directly into materials rather than heating an intermediary fluid like steam.
    5. Process Precision: Plasma torches enable controlled high-temperature heating, reducing overheating and improving manufacturing quality.

    Can Concentrated Solar Thermal (CST) Technologies Support Industrial Heat Requirements?

    Concentrated Solar Thermal (CST) technology, often known as Concentrated Solar Power (CSP), uses mirrors or lenses to focus a large area of sunlight onto a small receiver, generating high temperatures (often > 500 degree celcius). This thermal energy is captured by fluids (like oil or molten salt) to produce steam, driving turbines for electricity or providing direct industrial heat

    1. Solar Heat Generation: CST uses mirrors to concentrate sunlight onto receivers, heating fluids such as molten salts or water to temperatures up to 400°C.
    2. Suitable Industrial Applications: Textile processes like scouring and bleaching require temperatures between 100°C and 180°C, which CST can supply.
    3. Large National Potential: India possesses approximately 15 GW CST potential, indicating significant scalability.
    4. Declining Payback Period: Rising gas prices have reduced the payback period for CST installations from seven years to less than three years.
    5. On-site Energy Generation: CST enables industries to generate heat directly at factory premises, reducing reliance on external fuel supply.

    What Infrastructure Constraints Limit the Electrification of Industrial Heat?

    1. Grid Capacity Constraints: If large industrial clusters shift simultaneously to electric heating, existing power grids may face severe load pressure.
    2. Industrial Electricity Demand: Industrial heat already accounts for about 25% of total energy consumption, creating high electricity demand if electrified.
    3. Storage Limitations: India’s energy storage capacity remains underdeveloped, limiting round-the-clock renewable electricity supply.
    4. Distribution Network Stress: Studies indicate that up to one-third of transformers in industrial clusters operate near peak load, leaving minimal capacity for additional demand.
    5. High Voltage Requirements: Electric heating systems require high-capacity substations and reinforced transmission networks.

    How Can Thermal Storage Strengthen Industrial Electrification?

    1. Thermal Energy Storage: Heat generated during daytime can be stored in insulated tanks or molten salts for later industrial use.
    2. Lower Cost Advantage: Thermal storage systems are significantly cheaper than lithium-ion battery storage for industrial heat applications.
    3. Grid Independence: Stored heat enables factories to operate without continuous grid electricity supply.
    4. Peak Load Management: Thermal storage reduces electricity demand spikes during peak industrial operations.
    5. Round-the-Clock Operation: Industries can maintain 24×7 production cycles despite intermittent renewable energy generation.

    What Policy Measures Are Required to Accelerate Industrial Heat Electrification?

    1. National Thermal Policy: Establishes a coordinated framework for industrial heat decarbonisation and energy security.
    2. Targeted Subsidies: Extends production-linked incentives to CST mirror manufacturing, similar to solar photovoltaic incentives.
    3. Carbon Market Integration: Enables industries to trade avoided emissions through carbon credit markets, improving financial viability.
    4. Industrial Cluster Upgradation: Strengthens distribution infrastructure in manufacturing clusters to support electric heating.
    5. Energy Market Reform: Facilitates heat purchase agreements, allowing industries to buy heat as a service.

    What Global Experiences Offer Lessons for India’s Industrial Heat Transition?

    1. Hybrid Industrial Systems: Solar thermal systems operate during the day while gas-based systems provide backup at night.
    2. Oman Solar Thermal Project: Integration of large CST plants with gas-fired industrial operations reduces gas consumption by nearly 80%.
    3. Plug-and-Play Solar Systems: Modular solar thermal units allow quick installation in factory rooftops or parking areas.
    4. Energy Service Companies: External providers install and operate solar heat infrastructure, supplying heat at fixed prices.
    5. Market Reform Models: Liberalized energy markets allow heat supply contracts similar to electricity power purchase agreements.

    Conclusion

    Achieving greater thermal independence in industrial heat generation is essential for strengthening India’s energy security, industrial competitiveness, and climate commitments. Electrification of industrial heat and the adoption of concentrated solar thermal technologies can significantly reduce dependence on imported fossil fuels while improving efficiency and lowering emissions. However, this transition requires grid strengthening, thermal storage development, supportive policy frameworks, and targeted incentives for industries. A coordinated strategy integrating technology adoption, infrastructure expansion, and market reforms will be crucial to enable a resilient and sustainable industrial energy system in India.
