  • Government plans unification of port security regulations- sovereign entity to oversee private ports while CISF will regulate 80 ports

    Why In The News?

    The government has designated CISF as the security regulator for 250+ seaports to strengthen coastal security.

    1) New Security Framework:

    • Sovereign Entity at Seaports: Government to deploy CISF as a sovereign security force at private cargo-handling ports for a uniform security system.
    • Initial Coverage: CISF to regulate 80 major export-import seaports for access control, cargo screening, and seafront patrolling.
    • Phase-wise Expansion: Remaining 170 seaports will be brought under CISF in stages.
    • ISPS Code Role: CISF designated as the Recognised Security Organisation under the International Ship and Port Facility Security Code.

    2)Framework for Seaport Security in India:

    • International Ship and Port Facility Security (ISPS) Code:
      India’s port security system aligns with the mandatory global ISPS Code, introduced after 9/11 to protect ships and port facilities from terrorism and other maritime threats.
    • Central Industrial Security Force (CISF) as Security Regulator:
      The Government of India has recently designated the CISF as the Recognised Security Organisation (RSO) for ports, marking a major reform to strengthen and standardise port security across the country.

    3)Challenges to Port Security:

    • Non-Standardised Security Framework:
      • Security at many non-major ports historically lacked uniformity and expert oversight.
      • Heavy dependence on private security agencies or local police resulted in inconsistent standards.
    • Transnational & Non-Traditional Threats:
      • Maritime terrorism remains a persistent risk.
      • Smuggling and drug trafficking, with ports often used for large narcotics consignments.
      • Cyberattacks targeting port IT systems and critical infrastructure.
    • Infrastructure & Manpower Gaps:
      • Difficulty in ensuring uniform, high-quality security infrastructure across 250+ ports.
      • Significant manpower shortages: CISF requires 800-1,000 personnel per major seaport and has requested 10,000 additional personnel for initial deployment.
    • Coastal Vulnerabilities:
      • Large stretches of coastline remain open, poorly monitored, or unguarded.
      • Absence of a sovereign security force at private ports has created long-standing security gaps.
    • Identified Gaps in Official Reviews:
      • Coastal security flagged as a priority for discussion at the Director Generals of Police (DGP) Conference, attended by the Prime Minister.
      • The 2023 MHA guidelines highlighted major deficiencies and recommended comprehensive improvements.

    4) Committee Recommendations:

    • Committee Findings: A 2024 Joint Committee (CISF + Director General Shipping) conducted gap analysis and proposed corrective measures.
    • Hybrid Security Model: Core security functions to be handled by CISF, while State Police/private agencies manage non-core duties.

    Rising ‘Black Carbon’ heating Himalayan Snow: Study

    Why in the News?

    A recent study by the think-tank Climate Trends has revealed that levels of black carbon in the Himalayas have been rising steadily over the past two decades.

    About Black Carbon (BC):

    • What is it: Black carbon is a fine particulate pollutant formed from the incomplete combustion of biomass and fossil fuels.
    • Impact: It is a short-lived climate pollutant and the second-largest contributor to global warming after carbon dioxide.
    • Lifespan: Unlike CO₂, black carbon stays in the atmosphere for short periods and can be quickly reduced if emissions stop.
    • Warming Mechanism: As an aerosol, it absorbs sunlight, heats the atmosphere, and reduces albedo when deposited on snow and ice, leading to faster melting.
    • Health Effects: Exposure increases the risk of heart disease, birth complications, and premature death.
    • Major Sources in India:
      • Residential Biomass Burning: Accounts for 47% of BC emissions, including cow dung and straw burning.
      • Industries and Vehicles: Industries contribute 22%, while diesel vehicles add 17%.
      • Other Sources: Open burning contributes 12%, and other minor sources 2%.
      • High-Emission States: Madhya Pradesh and Maharashtra are major emitters due to agricultural and forest fires.
      • Biofuel Usage: Alone contributes nearly 42% of India’s total BC emissions.

    Key Findings from the Study (2000–2023):

    • Snow Temperature Rise: Himalayan snow surface temperature rose from -11.27°C to -7.13°C over two decades.
    • Regional Trends: The Eastern Himalayas were warmest, followed by the Central and Western regions.
    • BC Influence: Deposits of black carbon lower snow reflectivity, increase heat absorption, and accelerate glacier melt.
    • Population Risk: Glacier loss threatens the freshwater supply for nearly 2 billion people downstream.
    • Increase in Snow Depth: Despite warming, average snow depth rose from 0.059 m to 0.117 m.
    • Reasons: This is due to more snowfall, changing precipitation, and wind redistribution.
    • Regional Comparison: The Western Himalayas showed highest snow depth, linked to elevation and winter storms, while the Eastern and Central Himalayas had less snow due to proximity to BC sources.
