    Places in News: Kariyachalli Island

    Why in the News?

    The Tamil Nadu government, with World Bank support, has launched a ₹50 crore restoration project for the sinking Kariyachalli Island.

    About Kariyachalli Island:

    • Overview: Kariyachalli Island is one of the 21 uninhabited islands in the Gulf of Mannar Marine National Park.
    • Geographic Location: It lies 4 km south of Sippikulam and 20 km northeast of Thoothukudi, between Rameswaram and Thoothukudi.
    • Made of Reef Sediments: The island is a low-lying landform made of reef debris, sand dunes, spits, and sandy plains.
    • Biodiversity Hotspot: Located in India’s coral reef zone, it supports 4,300+ marine species, including 132 coral types and the endangered dugong.
    • Ecological Importance: It has seagrass beds and coral reefs that provide food and shelter for marine life.
    • Natural Coastal Shield: Kariyachalli acts as a barrier against cyclones and tsunamis, helping protect the Tamil Nadu coast.
    • Historical Significance: It played a role in mitigating the 2004 Indian Ocean tsunami impact.

    Why is it sinking?

    • Rapid Land Loss: The island has shrunk by over 70%, from 20.85 ha in 1969 to under 6 ha in 2024.
    • High Tide Erosion: At high tide, only 3.14 ha remains, per an IIT Madras (2025) study.
    • Wave and Sediment Pressure: Wave action, sediment loss, and lack of natural shoreline defense are accelerating erosion.
    • Climate Change Impact: Rising sea levels and coral bleaching have weakened the island’s natural protection.
    • Seagrass Depletion: Loss of seagrass beds has reduced the island’s ability to hold sediments and resist erosion.
    • Extreme Weather Events: Frequent cyclones and storms are making the island more vulnerable.
    • Future Risk: If the current trend continues, Kariyachalli may vanish by 2036.

    • Habitat: They prefer saltwater lagoons, mudflats, and saline lakes, and are important indicators of wetland health.
    • Migration Pattern: Every year, 100,000–150,000 flamingos migrate from Gujarat to Mumbai, typically arriving in November and settling in the Thane Creek Flamingo Sanctuary.
    • Migration Triggers: Their movement depends on food availability, water levels, and colony crowding.

    Jharkhand to set up its first Tiger Safari near Palamau TR

    Why in the News?

    The Jharkhand government has announced to establish its first tiger safari in the fringe area of the Barwadih Western Forest Range in Latehar district, which is part of the Palamau Tiger Reserve (PTR).

    What is a Tiger Safari?

    • About: A tiger safari is a tourist activity where visitors observe tigers in natural-like habitats, usually around tiger reserves.
    • Legal Status: The Wildlife Protection Act, 1972 does NOT define tiger safaris but restricts construction in protected areas unless approved by the National Board for Wildlife.
    • Policy Origin: The idea was formally introduced in 2012 by the National Tiger Conservation Authority (NTCA) under its tourism guidelines.
    • Rules on Tiger Inclusion (2016): Initially, safaris were allowed only in buffer or fringe zones and could host rescued or conflict tigers, not zoo-bred ones.
    • Amended Rules (2019): The NTCA later allowed even zoo-bred tigers, with Central Zoo Authority (CZA) in charge of animal welfare.
    • Supreme Court Ruling (2024): The court ordered that safaris must be built outside core and buffer zones to protect wild habitats.

    About Jharkhand’s Tiger Safari Project:

    • Location: Planned in the Barwadih Western Range, outside core and buffer zones of Palamau Tiger Reserve (PTR), in line with the Supreme Court’s order.
    • Animal Inclusion: Will house only rescued, injured, or orphaned tigers from various reserves and zoos — not wild tigers from PTR.
    • Tourism and Employment: The project aims to boost tourism and create jobs for around 200 locals as guides and staff.
    • Approval Process: The plan is still in early stages. After state Forest Department approval, a Detailed Project Report (DPR) will go to NTCA and CZA.

    Back2Basics: Palamu Tiger Reserve

    • It is located in Jharkhand’s Latehar and Garhwa districts, is one of India’s oldest tiger reserves, established under Project Tiger in 1973.
    • Spanning over 1,014 sq. km, it features a diverse landscape of valleys, hills, plains and is nourished by rivers like the North Koel, Auranga, and Burha.
    • The reserve is rich in moist and dry deciduous forests, dominated by Sal and bamboo.
    • It is home to key wildlife species, including tigers, Asiatic elephants, leopards, and sloth bears.

  • In news: Haji Pir Pass

    Why in the News?

    The recent Pahalgam terror attack has revived debates on India’s 1966 decision to surrender the Haji Pir Pass to Pakistan during Tashkent Agreement of 1966.

    This move is compared to the Soviet Union’s 1954 transfer of Crimea, which created lasting security challenges.

    About Haji Pir Pass:

    • The Haji Pir Pass is located in the Pir Panjal Range of Jammu and Kashmir, at an altitude of 2,637 meters (8,652 feet).
    • It connects Poonch in India to Rawalakot in Pakistan-occupied Kashmir (PoK).
    • Historically, it was a vital route for connecting Jammu to the Kashmir Valley before 1947, making it an essential part of India’s transportation network.
    • Post-partition, it became part of PoK and, during the 1965 Indo-Pak War, India recaptured it under Operation Bakshi.
    • However, it was returned to Pakistan following the Tashkent Agreement in 1966, a decision criticized by many experts.

    How Haji Pir Pass is a Chokepoint?

    • Strategic Military Route: The pass provides Pakistan with the ability to control and monitor the Kashmir Valley from a high-altitude position, serving as a key route for military logistics and infiltration.
    • Gateway for Infiltration: Historically, it has been used for militant infiltration into India, fuelling insurgency and instability in Kashmir.
    • Shortened Military Access: Retaining the pass would have reduced the distance between Poonch and Uri from 282 km to 56 km, improving India’s military logistics and rapid deployment.
    • Control over Key Terrain: Controlling the pass enables domination of the surrounding hills, limiting Pakistan’s ability to sustain military pressure and infiltration.

    The Critical Tiger Habitat (CTH) of Sariska Tiger Reserve (STR) in Rajasthan is set to expand by approximately 4,500 hectares.

    What is Critical Tiger Habitat (CTH)?

    • CTHs are designated under the Wildlife Protection Act (WLPA), 1972, to conserve tiger populations, keeping areas inviolate for tiger conservation.
    • The core areas of tiger reserves, where human activities are prohibited, serve as Critical Tiger Habitats.
    • Surrounding buffer zones allow sustainable human activities like eco-tourism and regulated resource use, supporting conservation efforts.
    • These areas are scientifically identified based on studies of tiger movement, breeding patterns, and environmental needs, ensuring long-term survival and ecological balance.
    • Scheduled Tribes and other forest dwellers’ rights are respected within the legal framework, making conservation inclusive.
    • The largest critical tiger habitat in India is the Nagarjunasagar-Srisailam Tiger Reserve (NSTR) spanning 5937 square kilometers.

    About Sariska Tiger Reserve (STR):

    • STR is located in Alwar district, Rajasthan, about 107 km from Jaipur, and is one of India’s most important tiger reserves.
    • Initially a royal hunting preserve, it became a sanctuary in 1955 and upgraded to a national park in 1979.
    • STR was one of the first tiger reserves under the Project Tiger initiative.
    • In 2008, after the tiger population was wiped out due to poaching and human encroachment, tigers were successfully relocated to the reserve, marking a world-first for tiger reintroduction.
    • Flora: STR has semi-deciduous forests, grasslands, rocky landscapes, and cliffs. The park is primarily dominated by dhok trees, covering around 90% of the area, alongside other species like salar, kadaya, and gol trees.
    • Fauna: The reserve is home to species like tigers, leopards, sambhar deer, nilgai, wild boars, rhesus macaques, and hyenas.
    • Ruparel River flows through STR, contributing to its ecological richness by supporting wildlife and plant species.
