Vizhinjam seaport
Why in news?
a. The Prime Minister of India inaugurated the Vizhinjam seaport in Kerala, enhancing India’s maritime infrastructure and boosting trade through strategic international shipping routes.
About Vizhinjam seaport:

- Location and Development:
- Vizhinjam Seaport is located in Vizhinjam, a coastal town in
Thiruvananthapuram District, Kerala.
-
- It is India’s first dedicated transhipment port and also the first semi-automated port in the country.
- Developed under the Public-Private Partnership (PPP) model at a cost of
₹8,900 crore, it is operated by the Adani Group, while the Kerala government holds the majority stake.
- Key Features:
- The port is equipped with cutting-edge infrastructure. It boasts India’s deepest breakwater, stretching nearly 3 kilometres, and a natural draft of 20 metres, making it capable of hosting large container vessels.
- Vizhinjam features India’s first AI-powered Vessel Traffic Management System, developed in collaboration with IIT Madras.
- The port also utilises automated yard cranes and remotely operated ship-to-shore cranes for enhanced operational efficiency.
- Notably, it experiences minimal littoral drift, reducing maintenance and dredging costs significantly.
- Strategic Significance:
-
- Positioned just 10 nautical miles from a key international shipping lane, Vizhinjam is strategically vital for India’s maritime ambitions.
- It aims to reclaim a major portion of India’s transhipment traffic, of which 75% was earlier handled by foreign ports, causing substantial foreign exchange losses.
- The port now shares routes with global maritime hubs like Shanghai, Singapore, and Busan.
- Plans are underway to develop Vizhinjam into a multi-modal logistics hub, integrating NH-66 highway connectivity, Kerala’s first cloverleaf interchange, and an upcoming rail link to the national network, enhancing India’s global trade footprint.
Palamu Tiger Reserve
Why in news?
a. After years of efforts, Jharkhand forest officials successfully relocated Jaigir village from Palamu Tiger Reserve’s core, marking a conservation milestone.
About Palamu Tiger Reserve:

- Location:
- Palamu Tiger Reserve is located in the Palamu, Latehar, and Garhwa districts of Jharkhand, spanning an area of 1,129.93 sq. km.
- It includes the Betla National Park and the Mahuadanr Wolf Sanctuary, forming a part of the Chotanagpur Plateau.
- Three rivers—North Koel, Burha, and Auranga—flow through the reserve, enriching its ecology.
- The elevation ranges from 300 to 1,140 meters, and the region receives an average rainfall of 1,075 mm annually.
- Flora and fauna:
- The reserve is home to a rich diversity of flora, primarily comprising deciduous forests with species such as sal and bamboo.
- The forest types include dry and moist sal forests, savannah woodlands, and
mixed deciduous patches.
-
- Over 970 plant species, including 56 medicinal and 17 grass species, are found here.
-
- In terms of fauna, Palamu hosts 47 mammal species and 174 bird species. Prominent mammals include the Bengal tiger, Indian leopard, sloth bear, gaur, elephants, and wolves.
- Avian diversity features peafowls, hornbills, owlets, kingfishers, and storks.
- Although tiger numbers once exceeded 50, habitat degradation and Naxal presence had reduced the count to one in 2022. Encouragingly, six tigers were recorded in 2025.
- Habitation within the reserve:
- Habitation within the reserve has historically been a concern. Several villages existed in the core and buffer areas, often lacking legal titles.
- Until recently, Jaigir, Kujrum, and Latu villages were within the core zone.
- However, successful relocation efforts aim to improve both human welfare and tiger conservation.
- Despite these efforts, issues like illegal grazing, poaching, staff shortages, and
infrastructure development continue to threaten the ecosystem.
