  • [28th July 2025] The Hindu Op-ed: How is India preparing against GLOF events?

    PYQ Relevance:

    [UPSC 2024] What is disaster resilience? How is it determined? Describe various elements of a resilience framework. Also mention the global targets of the Sendai Framework for Disaster Risk Reduction (2015-2030).

    Linkage: The article explicitly states that the NDMA has “markedly accelerated its efforts to manage these increasing risks” and initiated a “proactive shift from mere post-disaster response to risk reduction through its Committee on Disaster Risk Reduction (CoDRR)”. This directly links to the concept of “disaster resilience” and “Disaster Risk Reduction (DRR),” which are central to India’s preparedness strategy for GLOF events.

     

    Mentor’s Comment:  On July 8, 2025, Nepal experienced a major Glacial Lake Outburst Flood (GLOF), which triggered a flash flood along the Lende River, destroying a China-built friendship bridge and disabling four hydropower plants, cutting off 8% of Nepal’s power supply. This catastrophe highlights the growing threat of GLOFs due to glacial melt from rising temperatures in the Himalayas. The incident has raised concerns over the lack of trans-boundary early warning systems, particularly between China and Nepal. It also drew attention to India’s vulnerability, as the Indian Himalayan Region (IHR) contains 7,500 glacial lakes, many at high risk of GLOF due to climate change, poor monitoring infrastructure, and lack of early warning systems. India’s National Disaster Management Authority (NDMA) has responded by launching a national programme targeting 195 at-risk glacial lakes, focusing on hazard assessment, early warning systems, risk mitigation, and community engagement.

    Today’s editorial analyses the major Glacial Lake Outburst Flood (GLOF) in Himalaya region. This topic is important for GS Paper III (Environment) in the UPSC mains exam.

    _

    Let’s learn!

    Why in the News?

    Recently, Nepal faced a major Glacial Lake Outburst Flood (GLOF), which led to a sudden flash flood along the Lende River.  

    What are GLOFs?

    • GLOFs are sudden floods caused by the breach of natural or man-made dams holding glacial lakes, releasing large volumes of water.
    • Himalayan Spread: The Himalayas across India, Nepal, Bhutan, and Tibet host thousands of glacial lakes, many near international borders. India has 7,500+ glacial lakes, with 200+ deemed potentially dangerous.

     

    What are their transboundary risks in the Himalayas?

    • Trans-boundary Risk: GLOFs from upstream countries (e.g. China) can impact downstream nations (India, Nepal, Bhutan) without early warning. Eg: The July 2024 Tibetan GLOF damaged Nepal’s Rasuwagadhi hydropower project with no prior alert.
    • Lack of Data Sharing: Minimal real-time data exchange between neighbours hampers early warning and risk management. Eg: Nepal got no warning from China during the 2024 GLOF.

    How has climate change increased GLOF frequency in the IHR?

    • Accelerated Glacier Melting: Rising temperatures cause glacier retreat and formation of unstable glacial lakes. Eg: Milam Glacier, Uttarakhand shows rapid retreat, increasing GLOF risk.
    • Extreme Precipitation: Intense rainfall from climate change can overfill lakes, causing breaches. Eg: Gya GLOF (2014) in Ladakh followed heavy rainfall, damaging infrastructure.
    • Increased Landslides: Thawing permafrost and unstable slopes trigger landslides into lakes, displacing water and causing GLOFs. Eg: 2013 Chorabari Glacier landslide near Kedarnath worsened the flood impact.

    What measures has India taken for GLOF mitigation?

    • Early Warning Systems (EWS): Installed to detect rising water levels and trigger alerts. Eg: EWS at South Lhonak Lake, Sikkim before 2023 GLOF.
    • Satellite Monitoring: ISRO-NRSC use remote sensing to track glacial lakes. Eg: Monitored via Bhuvan portal in Ladakh, Uttarakhand, Himachal Pradesh.
    • Risk Mapping: NMSHE identifies high-risk areas for targeted intervention. Eg: Studies in Kinnaur and Chamoli flagged vulnerable lakes.
    • Engineering Measures: Lake drainage and structural control to prevent overflow. Eg: Work at Tsho Rolpa Lake (Nepal) as a replicable model.
    • Community Preparedness: NDMA and states run drills and awareness programs. Eg: Mock drills in Uttarkashi and Kullu.

    What are the gaps? 

    • Weak Early Warning Systems (EWS): India lacks real-time sensors, automated sirens, and alert mechanisms. Eg: No early alerts during Chamoli disaster (2021).
    • Low Community Preparedness: Most villages in Sikkim and Uttarakhand lack evacuation protocols and disaster training.
    • Poor Transboundary Coordination: Minimal data sharing with China hinders early action in regions like Arunachal Pradesh.
    • Infrastructure Vulnerability: Bridges and dams not designed for GLOFs.
      Eg: Chungthang dam breach (2023) exposed weak infrastructure.
    • Limited Scientific Capacity: Shortage of glaciologists, risk modelers, and ground validation limits NDMA’s effectiveness.

    Way forward: 

    •  Strengthen Early Warning Systems: Deploy real-time sensors, sirens, and automated alerts in high-risk zones.
    • Enhance Transboundary Cooperation: Establish formal data-sharing agreements with China, Nepal, and Bhutan.
    • Build Local Preparedness: Conduct regular community drills, awareness drives, and evacuation planning.
    • Climate-Resilient Infrastructure: Design dams, bridges, and power projects to withstand GLOF surges.
    • Invest in Research & Capacity: Train glaciologists, improve satellite-ground integration, and support Himalayan climate studies.

  • [26th July 2025] The Hindu Op-ed: Kargil, Pahalgam and a revamp of the security strategy

    PYQ Relevance:

    [UPSC 2016] The terms ‘Hot Pursuit’ and ‘Surgical Strikes’ are often used in connection with armed action against terrorist attacks. Discuss the strategic impact of such actions.

    Linkage: The article explicitly talks about the India’s shift in counter-terrorism strategy, mentioning the surgical strikes after the Uri attack (2016) and the Balakot strikes (2019) following Pulwama as “a strong reply” and “statement of intent”. The article culminates in discussing Operation Sindoor after the Pahalgam attack (2025), which involved striking terror bases and military air-bases deep in Pakistan, setting a “new threshold” for India’s response to terror.

     

    Mentor’s Comment: This year, in light of the recent Operation Sindoor (May 7–10, 2025), launched by India in response to the Pahalgam terror attack. The operation demonstrated India’s enhanced conventional military strength and shift in counter-terrorism doctrine, drawing parallels with the Kargil War’s legacy of structural reforms, military modernisation, and strategic assertiveness.

    Today’s editorial analyses the Indian Military strength. This topic is important for GS Paper III (Internal Security) in the UPSC mains exam.

    _

    Let’s learn!

    Why in the News?

    July 26, 2025, marks the 26th anniversary of the Kargil War, a key moment in India’s military history.

    What key shortcomings did Kargil expose?

    • Intelligence Failure: There was a complete lack of actionable intelligence about Pakistani infiltration. Eg: Neither RAW nor military intelligence anticipated the large-scale intrusion in the Kargil sector, resulting in delayed response.
    • Lack of Real-time Surveillance and Reconnaissance: India lacked advanced aerial and satellite surveillance capabilities. Eg: Absence of drone surveillance led to Pakistani troops occupying key heights undetected.
    • Operational Unpreparedness in High-altitude Warfare: Indian troops were not fully equipped or trained for fighting in extreme mountain conditions. Eg: Soldiers lacked snow boots, high-altitude tents, and artillery support during initial engagements.
    • Inadequate Military Modernisation and Logistics: Outdated weaponry and logistical weaknesses slowed the military’s response. Eg: Lack of precision-guided munitions and night-vision equipment hampered operations in the early phase of the conflict.

    How did they influence India’s military reforms?

    • Revamp of the Intelligence Infrastructure: The intelligence failure in Kargil led to the creation of dedicated and tech-enabled intelligence agencies. Eg: Establishment of the Defence Intelligence Agency (DIA) in 2002 and the National Technical Research Organisation (NTRO) in 2004 improved surveillance and early warning systems.
    • Modernisation and Capability Building: Recognising operational gaps, India focused on military modernisation and indigenous defence production. Eg: Induction of Rafale fighters, Apache helicopters, and BrahMos missiles, along with enhanced focus on ‘Make in India’ defence projects.
    • Structural and Doctrinal Reforms: The need for faster, joint response led to organisational restructuring and new doctrines. Eg: Appointment of the Chief of Defence Staff (CDS) in 2019 and development of the Cold Start Doctrineenabled swift, coordinated operations across services.

    How has India’s counter-terror strategy evolved from Kargil to Operation Sindoor?

    • Shift from Strategic Restraint to Active Retaliation: Initially, India responded passively to terror attacks, but now adopts swift and punitive action. Eg: In Operation Sindoor (2025), India launched precision strikes on nine terror bases and eleven military airbases inside Pakistan within 96 hours of the Pahalgam attack.
    • Use of Air Power and Missile Strikes: India has moved beyond surgical ground raids to deep-strike capabilities using air and missile assets. Eg: The BrahMos missile strike on Nur Khan Base in Pakistan reportedly crippled a nuclear weapons storage facility, sending a strong strategic signal.
    • Preemptive and Coordinated Operations: Focus has shifted to pre-empting terror threats through real-time intelligence and coordinated special operations. Eg: In 2023, India conducted a pre-emptive operation in Kashmir’s Gurez sector, dismantling a terror launchpad before infiltration.
    • Internationalising the Terror Narrative: India increasingly leverages diplomacy and global platforms to isolate Pakistan as a state sponsor of terror. Eg: Following the Pulwama attack (2019), India worked with global powers to get Masood Azhar designated as a global terrorist by the UN Security Council.
    • Integration of Technology and Intelligence Networks: There is now enhanced use of surveillance drones, cyber intelligence, and inter-agency coordination. Eg: Operation Black Thunder II (2024) used real-time intelligence sharing between NTRO, RAW, and special forces to eliminate a high-value terrorist in less than two days.

    What are the challenges for India? 

    • Persistent Cross-border Terrorism: Despite reforms, Pakistan-based terror groups continue to pose a threat, using proxy warfare and non-state actors to destabilize regions like Jammu & Kashmir.
    • Cybersecurity Vulnerabilities: India is increasingly vulnerable to cyberattacks on its military, energy, and communication infrastructure by hostile state and non-state actors. Eg: In 2023, a suspected Chinese-origin cyberattack targeted the power grid in Ladakh, exposing gaps in cyber defence preparedness.
    • Delays in Defence Modernisation: The slow pace of procurement, bureaucratic hurdles, and over-dependence on imports affect India’s combat readiness. Eg: Delays in acquiring high-altitude drones and next-generation tanks have impacted operational planning in sensitive border areas like Eastern Ladakh.

    Way forward: 

    • Promote Jointness and Modernisation: Implement integrated theatre commands and upgrade military technology to ensure faster, coordinated responses.
    • Strengthen Border and Cyber Security: Deploy smart surveillance systems and enhance cyber defence to counter both conventional and hybrid threats.

  • The scientist who made ‘mangroves’ a buzzword

    Why in the News?

    World Mangrove Day was observed on July 26. The occasion also recalled the pioneering role of M.S. Swaminathan in promoting mangrove conservation through initiatives like the International Society for Mangrove Ecosystems (ISME), GLOMIS, and the fishbone canal method of restoration.

    Role of M.S. Swaminathan in mangrove conservation

    • As early as 1989, he advocated using mangroves for climate resilience in coastal areas.
    • Proposed developing salinity-tolerant crops (e.g., rice) using mangrove genes.
    • Played a key role in founding the International Society for Mangrove Ecosystems (ISME) in 1990, promoting global knowledge exchange.
    • Co-authored the Charter for Mangroves, which was later included in the World Charter for Nature (1992) by the UN.
    • Led Community-Based Restoration in India through the M.S. Swaminathan Research Foundation (MSSRF).

    What is the ‘fishbone canal’ method? What are its advantages?

    The method mimics the natural branching pattern of rivers. It allows tidal waters to penetrate deep into degraded mangrove areas. Eg: In Tamil Nadu’s Pichavaram, fishbone canals revived previously stagnant mangrove zones, promoting natural seed dispersal.

    Advantages of the method

    1. Facilitates Natural Regeneration: By improving hydrology, it creates conditions suitable for natural mangrove seedling establishment without extensive manual planting. Eg: In Odisha’s Bhitarkanika, the method led to spontaneous growth of native mangrove species.
    2. Cost-Effective: Compared to large-scale planting, this method is less resource-intensive 
    3. It preserves ecosystem integrity.

    How have global and national initiatives reshaped mangrove management?

    • Shift Towards Community-Based Conservation: Focus has moved from government-led to community-driven models, recognising local knowledge and stakeholder participation. Eg: Eg: Sundarbans’ Joint Forest Committees empower villagers in conservation.
    • Integration with Climate Resilience Strategies: Mangroves are now seen as vital for disaster risk reduction and carbon sequestration. Eg: Indonesia’s “Mangroves for Coastal Resilience” project links mangrove conservation with coastal protection and blue carbon goals.
    • Technological Interventions and Scientific Planning: Use of GIS mapping, remote sensing, and hydrological modelling has made restoration more precise and scalable. Eg: In Andhra Pradesh, the Integrated Coastal Zone Management Project used satellite data to identify degraded mangrove areas for targeted restoration.

    How did India’s mangrove policy evolve post-1980 ?

    • CRZ Inclusion (1991): Mangroves declared ecologically sensitive under CRZ Rules, restricting commercial activity.
    • Post-Tsunami Shift (2004): Indian Ocean Tsunami highlighted mangroves as bio-shields, leading to their inclusion in disaster risk and coastal zone policies.
    • Boost in Support (Post-2005): Initiatives like the National Coastal Mission and remote sensing-based mapping promoted monitoring and restoration.

    What are ISME and GLOMIS?

    • ISME (International Society for Mangrove Ecosystems) is a global non-profit organization founded in 1990 to promote the conservation, restoration, and sustainable use of mangrove ecosystems through research, training, and international cooperation. It also offers technical support and capacity building for sustainable mangrove management.
    • GLOMIS (Global Mangrove Database and Information System), developed by ISME, is a centralized database that provides scientific data, GIS mapping, and case studies to support effective mangrove management and policymaking worldwide. GLOMIS serves as a database for mangrove species, restoration efforts, and GIS data.

    Way forward: 

    • Strengthen Community-Based Restoration: Empower local communities through training, sustainable livelihood support, and participation in restoration using techniques like the ‘fishbone canal’ method for greater ecological success.
    • Leverage Technology and Global Networks: Use remote sensing, GIS, and platforms like GLOMIS for monitoring mangrove health, while collaborating with international bodies like ISME to adopt best global practices.

    Mains PYQ:

    [UPSC 2019] Discuss the causes of depletion of mangroves and explain their importance in maintaining coastal ecology.

    Linkage: This question is directly and explicitly about mangroves, focusing on two key aspects: their depletion and their importance in maintaining coastal ecology. The fact that such a detailed question appeared in the examination signifies the recognized environmental importance and public awareness surrounding mangroves. A scientist’s work to popularize mangroves would logically contribute to this level of public and academic interest.
