    Jharkhand Plans First Tiger Safari

    The Jharkhand government is initiating plans to establish the state's first tiger safari in the Barwadih Western Forest Range, situated in Latehar district, which is part of the Palamau Tiger Reserve (PTR). This project is aimed at promoting tourism and serving as a conservation and educational center for wildlife, particularly for experiential learning and nature-based recreation. However, there are significant concerns regarding the potential displacement of local communities affected by this development.

    Key Points:

    • Project Overview: The proposed tiger safari will encompass approximately 150 hectares and will not feature wild animals. Instead, it will house conflict-prone, injured, or orphaned animals rescued from tiger reserves and zoos across India.

    • Regulatory Framework:

      • Under the Wildlife (Protection) Act, 1972, construction of commercial facilities inside sanctuaries requires approval from the National Board for Wildlife.
      • The National Tiger Conservation Authority (NTCA) first proposed the concept of tiger safaris in 2012 in its tourism guidelines, aiming to manage tiger sightings in well-regulated enclosures, particularly in buffer areas of tiger reserves.
      • In 2016, the NTCA issued guidelines for the establishment of such safaris specifically for rescued animals and amended these in 2019 to include zoo-bred animals with oversight from the Central Zoo Authority (CZA).
    • Supreme Court Directive: In March 2024, the Supreme Court mandated that tiger safaris must be developed outside the core and buffer zones of tiger reserves to avoid disruption of natural habitats and conservation efforts.

    • Economic Implications: The Jharkhand government anticipates that the tiger safari project will not only enhance tourism but also create around 200 direct job opportunities for locals in the tourism sector, including roles for guides and maintenance crews.

    • Implementation Timeline: Currently, the project is still in the ideation phase. Post approval from the Forest Department, a Detailed Project Report (DPR) will be prepared and submitted to the NTCA and CZA. The entire legislative approval process may take approximately five to six months, followed by an estimated construction period of 18 months.

    • Local Community Concerns:

      • Experts, such as tribal leaders from Karnataka's BRT Tiger Reserve, have pointed out that tiger safaris often sideline the contributions of local forest-dwelling communities and misrepresent them as threats to biodiversity.
      • Concerns have been voiced that the establishment of the safari could disrupt local economies by restricting access to customary activities such as livestock grazing and forest produce collection, which are vital for the livelihoods of many Adivasis.
      • Activists highlight the necessity for the Jharkhand government to secure consent from local communities through consultations with the Gram Sabha regarding the project’s potential impacts.

    Conclusion:

    While the establishment of a tiger safari in Jharkhand presents opportunities for tourism and job creation, it raises critical issues about the rights and livelihoods of local communities. The successful implementation of the project depends on considering these concerns to ensure that both tourism objectives and local community welfare are balanced in the conservation efforts of the region.

    Important Sentences:

    • The Jharkhand government aims to establish a tiger safari in Barwadih Western Forest Range to boost tourism and conservation efforts.
    • Under the Wildlife (Protection) Act, commercial tourist facilities require prior approval from the National Board for Wildlife.
    • The Supreme Court has directed that tiger safaris should be located outside the core and buffer areas of tiger reserves.
    • The project anticipates creating approximately 200 local jobs in the tourism sector.
