Report probes ecological risks in Karnataka’s proposed Mahadayi river diversion project

By Jag Jivan*   
A detailed independent study titled “Bhandura Nala (Mahadayi Diversion)”, prepared by a group of committed environmentalists from Karnataka and Goa, has strongly questioned the ecological and social viability of Karnataka government’s ambitious plan to divert water from the Mahadayi river basin (locally known as Mhadei in Goa) through the Bhandura Nala tunnel project.
The report, which has been widely circulated among civil society organisations and policymakers, warns of irreversible damage to the fragile Western Ghats ecosystem and raises the spectre of large-scale desertification in the region if such high-impact linear projects are allowed without rigorous scrutiny.
Renowned power and climate policy analyst Shankar Sharma, while forwarding the report to concerned citizens and organisations, described it as “a comprehensive and credible critique of the project proposal” that also discusses multiple viable alternatives to meet Karnataka’s stated water needs without resorting to ecologically destructive diversion.
In his strongly worded appeal, Sharma stated:
“This analysis provides a credible set of points to seriously ponder over for the entire society in view of the potential threats, such as desertification of the lands in and around the Western Ghats.”
He further highlighted the broader implications for peninsular India, noting that the Western Ghats are officially recognised by the Union Ministry of Environment, Forest and Climate Change (EF&CC) as “the water fountain of peninsular India”, being the origin of 37 east-flowing rivers and 3 major west-flowing rivers.
The Mahadayi diversion has remained a flashpoint between Karnataka and Goa for over two decades, with Goa consistently opposing any diversion on the grounds that it would devastate the biodiversity-rich Mhadei Wildlife Sanctuary and downstream ecosystems. The new independent report strengthens Goa’s position by documenting technical flaws, inadequate environmental impact assessments, and feasible non-diversion alternatives that Karnataka has allegedly ignored.
Sharma warned that the Bhandura Nala project is only one among nearly 50 high-impact linear projects already identified in Karnataka alone that cut through the Western Ghats, with dozens more planned or under implementation in Maharashtra, Kerala, and Goa. He termed the cumulative assault a “very serious issue for the entire peninsular India” and urged civil society organisations (CSOs) across the region to break their silence.
“The people of peninsular India, especially the concerned CSOs, cannot afford to be indifferent/silent on this specific project as well as other high impact project proposals in the Western Ghats,” Sharma wrote.  
“Let us do all that is feasible to effectively address the associated threats/costs to the larger society.”
Environmentalists associated with the report argue that diversion projects in the Western Ghats not only threaten endemic flora and fauna but also jeopardise the hydrological stability of the entire peninsula by disrupting the delicate rainfall catchment and recharge functions of this global biodiversity hotspot.
As the decades-old Mahadayi water dispute awaits final adjudication before the Supreme Court-appointed tribunal, the release of this independent technical critique is likely to intensify public and legal scrutiny of Karnataka’s diversion plans and reignite demands for a cumulative impact assessment of all linear projects in the Western Ghats.

Academics urge Azim Premji University to drop FIR against Student Reading Circle

  By A Representative   A group of academics and civil society members has issued an open letter to the leadership of Azim Premji University expressing concern over the filing of a police complaint that led to an FIR against a student-run reading circle following a recent incident of violence on campus. The signatories state that they hold the university in high regard for its commitment to constitutional values, critical inquiry and ethical public engagement, and argue that it is precisely because of this reputation that the present development is troubling.

Was Netaji forced to alter face, die in obscurity in USSR in 1975? Was he so meek?

  By Rajiv Shah   This should sound almost hilarious. Not only did Subhas Chandra Bose not die in a plane crash in Taipei, nor was he the mysterious Gumnami Baba who reportedly passed away on 16 September 1985 in Ayodhya, but we are now told that he actually died in 1975—date unknown—“in oblivion” somewhere in the former Soviet Union. Which city? Moscow? No one seems to know.

UAPA action against Telangana activist: Criminalising legitimate democratic activity?

Asbestos contamination in children’s products highlights global oversight gaps

By A Representative   A commentary published by the International Ban Asbestos Secretariat (IBAS) has drawn attention to the challenges governments face in responding effectively to global public-health risks. In an article written by Laurie Kazan-Allen and published on March 5, 2026, the author examines how the discovery of asbestos contamination in children’s play products has raised questions about regulatory oversight and international product safety. The article opens by reflecting on lessons from the COVID-19 pandemic, noting that governments in several countries were slow to respond to early warning signs of the crisis. Referring to the experience of the United Kingdom, the author writes that delays in implementing protective measures contributed to “232,112 recorded deaths and over a million people suffering from long Covid.” The commentary uses this example to illustrate what it describes as the dangers of underestimating emerging threats. Attention then turns...

Aligning too closely with U.S., allies, India’s silence on IRIS Dena raises troubling questions

By Vidya Bhushan Rawat*  The reported sinking of the Iranian ship IRIS Dena in the Indian Ocean near Sri Lanka raises troubling questions about international norms and the credibility of the so-called rule-based order. If indeed the vessel was attacked by the American Navy while returning from a joint exercise in Visakhapatnam, it would represent a serious breach of trust and a violation of the principles that govern such cooperative engagements. Warships participating in these exercises are generally not armed for combat; they are meant to symbolize solidarity and friendship. The incident, therefore, is not only shocking but also deeply ironic.

The kitchen as prison: A feminist elegy for domestic slavery

By Garima Srivastava* Kumar Ambuj stands as one of the most incisive voices in contemporary Hindi poetry. His work, stripped of ornamentation, speaks directly to the lived realities of India’s marginalized—women, the rural poor, and those crushed under invisible forms of violence. His celebrated poem “Women Who Cook” (Khānā Banātī Striyāṃ) is not merely about food preparation; it is a searing indictment of patriarchal domestic structures that reduce women’s existence to endless, unpaid labour.

Nalanda mahavihara By Rajiv Shah  Prominent historian DN Jha, an expert in India's ancient and medieval past, in his new book , "Against the Grain: Notes on Identity, Intolerance and History", in a sharp critique of "Hindutva ideologues", who look at the ancient period of Indian history as "a golden age marked by social harmony, devoid of any religious violence", has said, "Demolition and desecration of rival religious establishments, and the appropriation of their idols, was not uncommon in India before the advent of Islam".
