  • Salt Marsh Restoration on Oléron Island

    Why in News?

    The revival of the traditional salt harvesting profession on Oléron Island, France, is gaining attention as restored salt marshes help protect coastal areas from the increasing impacts of climate change, especially marine flooding.

    Key Highlights

    • The profession of salt worker disappeared from Oléron Island in the 1980s but has been revived with support from local authorities.
    • Salt marshes are being restored not only for salt production but also as a nature-based solution for climate adaptation.
    • These marshes act as buffer zones, reducing the impact of coastal flooding and storm surges.
    • Climate change has increased the frequency and intensity of marine flooding, making coastal ecosystem restoration increasingly important.

    What are Salt Marshes?

    • Salt marshes are coastal wetlands found in the intertidal zone between land and sea.
    • They are regularly flooded by seawater during high tides.
    • They are dominated by salt-tolerant (halophytic) vegetation such as grasses, sedges, and shrubs.
    • Salt marshes commonly occur in estuaries, lagoons, deltas, and sheltered coastlines.

    Ecological Importance

    • Act as natural buffers, reducing the impact of storm surges and coastal erosion.
    • Absorb and store excess floodwater, lowering flood risks.
    • Trap sediments and improve water quality.
    • Serve as breeding and nursery grounds for fish, crustaceans, and migratory birds.
    • Store large amounts of blue carbon, helping mitigate climate change.

    What is Blue Carbon?

    • Blue carbon refers to carbon captured and stored by coastal and marine ecosystems such as: Mangroves, Salt marshes, and Seagrass meadows
    • These ecosystems sequester carbon in both vegetation and underlying sediments for long periods.

    Threats to Salt Marshes

    • Coastal development and land reclamation.
    • Sea level rise due to climate change.
    • Pollution and eutrophication.
    • Conversion for agriculture and aquaculture.
    • Alteration of natural tidal flows.

    Relevance for India

    • India has significant coastal wetlands, including mangroves, salt marshes, mudflats, and seagrass meadows, which play a crucial role in coastal protection and climate resilience.
    • Restoration of these ecosystems supports India’s commitments under the Ramsar Convention, National Coastal Mission, and climate adaptation strategies.

    [2021] What is blue carbon?

    [A] Carbon captured by oceans and coastal ecosystems

    [B] Carbon sequestered in forest biomass and agricultural soils

    [C] Carbon contained in petroleum and natural gas

    [D] Carbon present in atmosphere

  • Mount Marapi Eruption in Indonesia

    Why in News?

    Mount Marapi, one of Indonesia’s most active volcanoes, erupted again, sending an ash column about 2 km high into the sky over West Sumatra’s Tanah Datar District. Authorities continue to enforce a 3 km exclusion zone around the volcano.

    Note: This volcano is Mount Marapi (West Sumatra), not Mount Merapi (Central Java). They are two different active volcanoes in Indonesia.

    Key Highlights

    • The eruption produced an ash plume reaching approximately 2 km above the summit.
    • A 3 km exclusion zone remains in force following the deadly eruption in December 2023.
    • Authorities have advised residents and tourists to stay away from the crater due to the risk of further eruptions.
    • Indonesia frequently experiences volcanic eruptions because of its tectonic setting.

    About Mount Marapi

    • Located in West Sumatra Province, Indonesia.
    • Elevation: 2,891 metres.
    • It is one of the most active volcanoes in Sumatra.
    • It is a stratovolcano (composite volcano) characterized by frequent explosive eruptions.

    What is a Stratovolcano?

    • A stratovolcano is formed by alternating layers of lava, volcanic ash, and pyroclastic material.
    • It has steep slopes and is associated with explosive eruptions because of silica-rich, viscous magma.
    • Examples include Mount Fuji (Japan), Mount Merapi (Indonesia), and Mount St. Helens (USA).

    Why is Indonesia Highly Prone to Volcanic Activity?

    • Indonesia lies on the Pacific Ring of Fire, a zone of intense volcanic and seismic activity.
    • It is located at the convergence of the Indo Australian, Eurasian, Pacific, and Philippine Sea tectonic plates.
    • The country has more than 120 active volcanoes, the highest number in the world.

    Prelims Facts

    • Pacific Ring of Fire contains about 75% of the world’s active volcanoes and experiences nearly 90% of global earthquakes.
    • Volcanic hazards include ashfall, lava flows, pyroclastic flows, volcanic gases, and lahars (volcanic mudflows).

    [2024] Consider the following:
    1. Pyroclastic debris

  • Matcha Tea: India’s First Commercially Produced Matcha

    Why in News?

    An Assam tea estate, Chota Tingrai Tea Estate in Tinsukia district, has produced and sold India’s first commercially produced matcha tea at the Guwahati Tea Auction Centre, marking India’s entry into the premium global matcha market.

    What is Matcha?

    • Matcha is a finely powdered green tea made from specially cultivated shade-grown leaves of Camellia sinensis.
    • Unlike conventional green tea, where leaves are steeped and discarded, the entire powdered leaf is consumed, providing higher nutritional benefits.

    How is Matcha Produced?

    • Tea plants are shaded for 3 to 4 weeks before harvest.
    • Around 90% of sunlight is blocked, resulting in:
      • Increased chlorophyll content (bright green colour).
      • Higher L-theanine (amino acid) levels.
      • Enhanced antioxidants and natural caffeine.
    • Young leaves are Steamed to prevent oxidation, Dried, De-stemmed and de-veined, Stone-ground into a fine green powder.

    How is Matcha Different from Green Tea?

    • Matcha uses shade-grown tea leaves, whereas ordinary green tea is generally grown under normal sunlight.
    • In matcha, the entire powdered leaf is consumed, while in green tea the leaves are steeped in water and then discarded.
    • Matcha contains higher levels of chlorophyll, antioxidants, L-theanine, and natural caffeine.
    • It has a rich umami flavour and vibrant green colour.

  • Coal Imports Decline by Nearly 13% in April 2026

    Why in News?

    India’s coal imports declined by 12.95% in April 2026 compared to April 2025, reflecting the government’s continued push towards import substitution through higher domestic coal production and improved supply logistics.

    Key Highlights

    • Total coal imports fell from 24.27 MT (April 2025) to 21.13 MT (April 2026), a decline of 12.95%.
    • Power sector coal imports declined by 24.89%, from 4.67 MT to 3.51 MT.
    • Imported Coal-Based (ICB) power plants recorded the steepest fall in imports: 3.97 MT → 2.88 MT (down 27.45%).
