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.

From colonial mercantilism to Hindutva: New book on the making of power in Gujarat

By Rajiv Shah  Professor Ghanshyam Shah ’s latest book, “ Caste-Class Hegemony and State Power: A Study of Gujarat Politics ”, published by Routledge , is penned by one of Gujarat ’s most respected chroniclers, drawing on decades of fieldwork in the state. It seeks to dissect how caste and class factors overlap to perpetuate the hegemony of upper strata in an ostensibly democratic polity.

From protest to proof: Why civil society must rethink environmental resistance

By Shankar Sharma*  As concerned environmentalists and informed citizens, many of us share deep unease about the way environmental governance in our country is being managed—or mismanaged. Our complaints range across sectors and regions, and most of them are legitimate. Yet a hard question confronts us: are complaints, by themselves, effective? Experience suggests they are not.

Urgent need to study cause of large number of natural deaths in Gulf countries

By Venkatesh Nayak* According to data tabled in Parliament in April 2018, there are 87.76 lakh (8.77 million) Indians in six Gulf countries, namely Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates (UAE). While replying to an Unstarred Question (#6091) raised in the Lok Sabha, the Union Minister of State for External Affairs said, during the first half of this financial year alone (between April-September 2018), blue-collared Indian workers in these countries had remitted USD 33.47 Billion back home. Not much is known about the human cost of such earnings which swell up the country’s forex reserves quietly. My recent RTI intervention and research of proceedings in Parliament has revealed that between 2012 and mid-2018 more than 24,570 Indian Workers died in these Gulf countries. This works out to an average of more than 10 deaths per day. For every US$ 1 Billion they remitted to India during the same period there were at least 117 deaths of Indian Workers in Gulf ...

The architect of Congolese liberation: The life and legacy of Patrice Lumumba

By Harsh Thakor*  Patrice Émery Lumumba remains a central figure in the history of African decolonization, serving as the first Prime Minister of the independent Republic of the Congo. Born on July 2, 1925, Lumumba emerged as a radical anti-colonial leader who sought to unify a nation fractured by decades of Belgian rule. His tenure, however, lasted less than seven months before his dismissal and subsequent assassination on January 17, 1961.

ArcelorMittal faces global scrutiny for retreat from green steel, job cuts, and environmental violations

By  Jag Jivan    ArcelorMittal is facing mounting criticism after cancelling or delaying nearly all of its major green steel projects across Europe, citing an “unsupportive policy environment” from the European Union . The company has shelved projects in Germany , Belgium , and France , while leaving the future of its Spanish decarbonisation plan uncertain. The decision comes as global unions warn that more than 5,500 jobs are at risk across its operations, including 4,000 in South Africa , 1,400 in Europe, and 160 in Canada .

Venezuela and the crisis of global order: Erosion of rules-based international order

By Vidya Bhushan Rawat*  The American attack on Venezuela violates every principle of international law that the collective West claims to uphold. The response from the European Union—“we are monitoring the situation”—exposes the hollowness of these claims. WhatsApp gossipers may celebrate this as an act of “bravery,” but what kind of bravery is it to intimidate a neighbour that is neither large in size nor strong in military power? 

A comrade in culture and controversy: Yao Wenyuan’s revolutionary legacy

These milestones invite reflection on the man whose pen ignited the first sparks of the Great Proletarian Cultural Revolution and whose sharp ideological interventions left an indelible imprint on the political and cultural landscape of socialist China.
