1. Shompen Tribe of Nicobar
Sub: Geography | Section: Human Geography
Why in News:
The Shompen tribe of the Nicobar Islands has come into the spotlight due to concerns over a major infrastructure project on Great Nicobar Island, which threatens their forest home. The project includes a transshipment container terminal, port, and solar power plant, raising environmental and anthropological concerns.

About Shompen Tribe:
The Shompen tribe is a semi-nomadic, forest-dwelling community that has inhabited the Great Nicobar Island for over 60,000 years. Unlike the coastal Nicobarese tribe, the Shompen live in the island’s interior, relying heavily on the forest for their sustenance.
- They are one of the most isolated Particularly Vulnerable Tribal Groups (PVTGs) in India.
- Semi-nomadic hunter-gatherers, they rely on hunting, gathering, fishing, and rudimentary horticulture.
- Their staple food is the pandanus fruit, and they speak their own language, often unintelligible even between bands.

2. Use of Salt Pan Land for Housing: Ecological and Urban Planning Concerns in Mumbai
Sub: Geography | Section: Economic Geography
Why in News:
The Maharashtra government has allocated 255.9 acres of salt pan land in Mumbai’s eastern suburbs for the construction of rental housing as part of the Dharavi Redevelopment Project. Environmentalists have raised concerns about the impact of converting salt pan land, which serves as natural flood defenses.

What are Salt Pan Lands?
Salt pans are low-lying lands where seawater flows in and evaporates, leaving behind salt and minerals. They play an essential role in the ecosystem by acting as natural flood buffers.
- Mumbai has 5,378 acres of salt pan land.
- Coastal Regulation Zone (CRZ) laws restrict development on salt pans.

Interesting Fact | The Production Linked Incentive (PLI) Scheme has been introduced to boost domestic manufacturing of pharmaceuticals, including anti-cancer drugs. |
Relevance | This is crucial for topics related to public health and pharmaceutical safety in India, as well as efforts to regulate and improve healthcare infrastructure. |
7. Two Months On, Meghalaya Polio Case Shrouded in Secrecy
Sub: Science | Section: Health
Background:
A recent polio case in Meghalaya has raised concerns due to the government’s lack of transparency. Reports indicate conflicting statements from officials, leading to fears of a cover-up, similar to how the Indian government was criticized for not fully disclosing Zika virus cases in 2017.
Vaccine-Derived Polio (VDP):
The polio case in question appears to be vaccine-derived, caused by a strain of poliovirus that mutated from the strain in the Oral Polio Vaccine (OPV). This rare situation can occur when the weakened virus in OPV mutates and circulates in under-vaccinated communities.
Section | Details |
---|---|
Do You Know? | Circulating vaccine-derived poliovirus (cVDPV) is rare but can cause outbreaks in areas with poor sanitation and low vaccination coverage. |
Background | Polio was eradicated from India in 2014, but vaccine-derived cases can still arise in communities where polio vaccination coverage is incomplete. |
Interesting Fact | India switched to using the Inactivated Polio Vaccine (IPV) after eradicating wild polio, though OPV is still used in some cases. |
Relevance | This case highlights the need for sustained immunization efforts and the challenges of managing public health risks in developing regions. |
