    The Union Environment Ministry has rolled out norms for the Green Credit Programme (GCP).

    Guidelines and Modifications:

    1. The Environment Ministry’s recent guidelines empower ‘States’ to determine afforestation density based on local conditions, acknowledging the variability in forest ecosystems.
    2. Indigenous species are prioritized, and naturally occurring seedlings are retained to foster ecosystem resilience.

    What is Green Credit Programme (GCP)?

    • The GCP as notified on October 13, 2023 by the government of India, is an innovative market-based mechanism.
    • This program is part of the broader ‘LiFE’ campaign (Lifestyle for Environment), and it encourages and rewards voluntary environmentally positive actions.
    • It involves various stakeholders like- individuals, farmers, communities, private sector industries, and companies.
    • The Indian Council of Forestry Research and Education (ICFRE), based in Dehradun, serves as the GCP Administrator, responsible for programme implementation, management, monitoring, and operation.
    • Initially, the GCP focuses on water conservation and afforestation.

    What are Green Credits?

    • The green credit rules notified under the Environment (Protection) Act 1986 defines ‘green credit’ as a single unit of an incentive provided for a specific activity that delivers a positive impact on the environment.
    • Each tree planted and evaluated by the ICFRE after two years could yield one ‘green credit,’ which can be utilized in two ways:
    1. Compliance with forest laws necessitating recompense for forest land diversion.
    2. Reporting under environmental, social, and governance norms or meeting corporate social responsibility requirements.

    Notable Feature: Green Credit Registry

    • The ICFRE, alongside experts, is developing the Green Credit Registry and trading platforms to facilitate the registration, buying, and selling of green credits.
    • To obtain green credits, individuals and entities must register their activities through the central government’s dedicated app/website (www.moefcc-gcp.in).
    • The administrator verifies activities through a designated agency, with self-verification for small projects. Once verified, the administrator issues a tradeable green credit certificate.

    Activities under GCP

    The GCP includes numerous activities, such as:

    Description
    Tree Plantation-based Green Credit Promotes increasing the green cover through tree plantations and related activities.
    Water-based Green Credit Promotes water conservation, harvesting, and efficiency, including wastewater treatment and reuse.
    Sustainable Agriculture-based Green Credit Promotes natural and regenerative agricultural practices, land restoration, and soil health improvement.
    Waste Management-based Green Credit Promotes sustainable waste management practices, including collection, segregation, and treatment.
    Air Pollution Reduction-based Green Credit Promotes measures to reduce air pollution and other pollution abatement activities.
    Mangrove Conservation and Restoration-based Green Credit Promotes conservation and restoration of mangroves, critical ecosystems for coastal protection and biodiversity.

  • KAVACH Anti-Collision System

    The Supreme Court has acknowledged and appreciated the implementation of the indigenous anti-collision system KAVACH.

    What is KAVACH?

    • Kavach, an automatic train protection (ATP) system, was initially named Train Collision Avoidance System (TCAS).
      • Development commenced in 2011 as Indian Railways and Research Designs & Standards Organisation (RDSO) sought a domestically developed ATP system.
      • B. Rajaram, credited with developing the Skybus Metro system, played a key role in Kavach’s development.
      • Field trials began in 2014, refining the system’s specification.
    • Final approval was granted in 2019, certifying Kavach for compliance with Safety Integrity level 4 (SIL-4) operations.

    Working Mechanism:

    • Kavach comprises trackside Radio Frequency Identification (RFID) tags, onboard locomotive equipment, and radio infrastructure.
    • It communicates via radio, enabling real-time train monitoring.
    • Drivers receive alerts, and automatic braking is triggered to prevent collisions.
    • Kavach uses various data inputs like location, direction, and time to ensure safety.
    • Event recorders retain records of interactions and incidents for analysis.
    • Alerts and automatic braking ensure an immediate response to hazardous situations.

    How does it help prevent collision?

    • Kavach is designed to alert the locomotive pilot if they fail to notice a ‘red signal’ and continue at a speed that would surpass the signal.
    • If the pilot does not slow down below 15 kmph, Kavach automatically applies the brakes, bringing the train to a halt.

    Issues with KAVACH

    • High Deployment Cost: Implementing Kavach costs ₹50 lakh per kilometer for the Indian Railways.
    • Low Coverage: Currently, Kavach covers only 1,500 kilometers of rail routes, a small fraction of the total 68,000-kilometer network (as of November 2023).
      • Expanding its coverage, particularly on high-density routes, remains a formidable challenge.

  • India could face ‘Imported Inflation’: Asian Development Bank (ADB)

    Why in the News?

    The Asian Development Bank recently issued a cautionary note for India’s susceptibility to imported inflation due to potential rupee depreciation amidst escalating interest rates in the West.

    What is Imported Inflation?

    • Imported inflation refers to the increase in the prices of goods and services within a country caused by a rise in the cost or price of imports.
    • This phenomenon occurs when factors such as a depreciating currency, higher import costs, or increased international prices lead to elevated expenses for imported goods and services.
    • Consequently, producers may adjust their prices upward to offset these higher costs, resulting in inflationary pressures within the domestic economy.
    • This idea connects with the theory of cost-push inflation, which means that when input costs go up, it can cause prices for final products to go up too.

    Reason behind the imported inflation:

    • Capital Flows: Increased interest rates in Western economies attract foreign investors seeking higher returns, leading to capital outflows from countries like India and potentially depreciating the Indian rupee.
      • When a currency depreciates, local consumers require more of their domestic currency to procure foreign goods, consequently elevating import prices.
    • Borrowing Costs: Indian businesses and the government may face higher borrowing costs for infrastructure projects and investments if they raise funds in foreign currency-denominated international markets.
    • Inflationary Pressures: Capital outflows can pressure the Indian rupee, causing imported inflation as the cost of imported goods rises due to currency depreciation.
    • Trade Competitiveness: Exchange rate fluctuations from Western interest rate changes affect India’s trade competitiveness, impacting exports, imports, and domestic consumption.

  • What is Exoatmospheric Interception?

    Why in the news?

    Israel successfully intercepted an Iranian missile outside Earth’s atmosphere using an Exoatmospheric kill vehicle.

    Israeli Air-Defence Systems


    Israel’s multi-layered air defence system, including Iron Dome, The Arrow, and David’s Sling, was activated in anticipation of the attack.

    1. IRON DOME: The short-range Iron Dome air defence system was built to intercept the kind of rockets fired by the Hamas in Gaza. Developed by state-owned Rafael Advanced Defense Systems with US backing, it became operational in 2011. Each truck-towed unit fires radar-guided missiles to blow up short-range threats like rockets, mortars and drones in mid-air.
    2. ARROW: The long-range Arrow-2 and Arrow-3 system, developed by Israel with an Iranian missile threat in mind, is designed to intercept ballistic missiles outside the earth’s atmosphere, using a detachable warhead that collides with the target. It operates at an altitude that allows for the safe dispersal of any non-conventional warheads.
    3. DAVID’S SLING: This mid-range system is designed to shoot down ballistic missiles fired from 100 km to 200 km away. Developed and manufactured jointly by Israel’s state-owned Rafael Advanced Defense Systems and the U.S. Raytheon Co, David’s Sling is also designed to intercept aircraft, drones and cruise missiles.

    What are Exoatmospheric Missiles?

    • Exoatmospheric missiles, or anti-ballistic missiles (ABMs), operate beyond Earth’s atmosphere to intercept incoming ballistic missiles.
    • They employ advanced sensors and guidance systems to detect, track, and destroy targets in space.
    • Kinetic kill vehicles, like the Exoatmospheric Kill Vehicle (EKV), rely on high-speed collisions to neutralize threats.
    • It travels at hypersonic speed.

    Working Mechanism of Exoatmospheric Missiles:

    • The EKV uses a solid rocket booster to propel itself into space.
    • Advanced sensors and onboard computers identify and track incoming threats.
    • Precise maneuvering allows the missile to navigate towards the target.
    • Impact from a high-speed collision eliminates the threat without traditional warheads, enhancing speed and accuracy.
