Biodiversity decline persists despite expansion of protected areas, letter to Centre warns

By A Representative

A representation submitted to the Union Ministry of Environment, Forest and Climate Change has raised serious concerns over what it describes as the rapid erosion of ecological safeguards within India’s legally protected areas, citing recent global research and the proposed approval of a major pumped storage project inside a wildlife sanctuary in Karnataka.

In a letter dated December 18, 2025, addressed to Union Minister for Environment, Forest and Climate Change Bhupender Yadav and Minister of State Kirti Vardhan Singh, and copied to the Prime Minister, power and climate policy analyst Shankar Sharma drew attention to a recent international study reported by Down To Earth that questions the effectiveness of expanding protected areas in halting biodiversity loss. The study warns that while the global coverage of protected areas has increased, biodiversity continues to decline within many such sites, raising concerns that policy targets are prioritising numerical expansion over actual ecological outcomes.

Referring to the Indian context, the letter argues that the situation is particularly worrying, with authorities continuing to clear development projects even within wildlife sanctuaries and eco-sensitive zones. While official narratives often highlight the creation of new protected areas, the submission contends that these gains are undermined by frequent diversions of forest land, allegedly approved without adequate assessment of ecological necessity or alternatives.

The representation highlights data indicating that India lost more than 120,000 hectares of primary forest between 2014 and 2019, a figure said to be nearly 36 percent higher than losses recorded between 2009 and 2013. It also points to reports that over 500 projects in protected areas and eco-sensitive zones were cleared by the National Board for Wildlife between June 2014 and May 2018. According to the letter, India’s total forest and tree cover now stands at about 22 percent of its land area, significantly below the National Forest Policy target of 33 percent, a gap the author says is unlikely to be bridged if current clearance trends continue.

Against this backdrop, the letter expresses strong opposition to the in-principle approval accorded to a proposed 2,000 MW pumped storage project in the Sharavathi Lion-Tailed Macaque Sanctuary in Karnataka, a region within the Western Ghats, which is recognised as a global biodiversity hotspot. The project received clearance during the 84th meeting of the Standing Committee of the National Board for Wildlife. The submission argues that approving large infrastructure projects within sanctuaries represents a serious threat to wildlife habitats, endangered species and freshwater ecosystems.

The letter contrasts the rationale often given for permitting small projects inside protected areas—such as water pipelines or communication towers, which are justified as having no viable alternatives—with what it terms the “irrational and irresponsible” approval of a large pumped storage project despite the availability of alternative energy storage solutions such as battery energy storage systems. It also claims that the Sharavathi project has faced widespread public opposition, including objections from officials within the state forest department and concerns raised by Indian Forest Service officers associated with the Union ministry.

The author questions the strength of the ministry’s commitment to environmental protection in light of the Sharavathi proposal and two other pumped storage projects planned in Karnataka. He urges the Union government to reject all three projects and to undertake a comprehensive review of pumped storage proposals in river valleys across the country, taking into account less ecologically damaging alternatives.

The representation concludes with an appeal for a more precautionary and science-based approach to development decisions within protected areas, warning that continued deforestation and habitat fragmentation could have long-term consequences for biodiversity, water security and the overall well-being of communities dependent on healthy ecosystems.

Grueling summer ahead: Cuttack’s alarming health trends and what they mean for Odisha

By Sudhansu R Das The preparation to face the summer should begin early in Odisha. People in the state endure long, grueling summer months starting from mid-February and extending until the end of October.

Stronger India–Russia partnership highlights a missed energy breakthrough

By N.S. Venkataraman* The recent visit of Russian President Vladimir Putin to India was widely publicized across several countries and has attracted significant global attention. The warmth with which Mr. Putin was received by Prime Minister Narendra Modi was particularly noted, prompting policy planners worldwide to examine the implications of this cordial relationship for the global economy and political climate. India–Russia relations have stood on a strong foundation for decades and have consistently withstood geopolitical shifts. This is in marked contrast to India’s ties with the United States, which have experienced fluctuations under different U.S. administrations.

Concerns raised over move to rename MGNREGA, critics call it politically motivated

By A Representative Concerns have been raised over the Union government’s reported move to rename the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), with critics describing it as a politically motivated step rather than an administrative reform. They argue that the proposed change undermines the legacy of Mahatma Gandhi and seeks to appropriate credit for a programme whose relevance has been repeatedly demonstrated, particularly during times of crisis.

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

By Harsh Thakor* This year marks two important anniversaries in Chinese revolutionary history—the 20th death anniversary of Yao Wenyuan, and the 50th anniversary of his seminal essay "On the Social Basis of the Lin Biao Anti-Party Clique". 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.

From natural farming to fair prices: Young entrepreneurs show a new path

By Bharat Dogra There have been frequent debates on agro-business companies not showing adequate concern for the livelihoods of small farmers. Farmers’ unions have often protested—generally with good reason—that while they do not receive fair returns despite high risks and hard work, corporate interests that merely process the crops produced by farmers earn disproportionately high profits. Hence, there is a growing demand for alternative models of agro-business development that demonstrate genuine commitment to protecting farmer livelihoods.

Swami Vivekananda's views on caste and sexuality were 'painfully' regressive

By Bhaskar Sur* Swami Vivekananda now belongs more to the modern Hindu mythology than reality. It makes a daunting job to discover the real human being who knew unemployment, humiliation of losing a teaching job for 'incompetence', longed in vain for the bliss of a happy conjugal life only to suffer the consequent frustration.

Why India must urgently strengthen its policies for an ageing population

By Bharat Dogra A quiet but far-reaching demographic transformation is reshaping much of the world. As life expectancy rises and birth rates fall, societies are witnessing a rapid increase in the proportion of older people. This shift has profound implications for public policy, and the need to strengthen frameworks for healthy and secure ageing has never been more urgent. India is among the countries where these pressures will intensify most sharply in the coming decades.

Thota Sitaramaiah: An internal pillar of an underground organisation

By Harsh Thakor* Thota Sitaramaiah was regarded within his circles as an example of the many individuals whose work in various underground movements remained largely unknown to the wider public. While some leaders become visible through organisational roles or media attention, many others contribute quietly, without public recognition. Sitaramaiah was considered one such figure. He passed away on December 8, 2025, at the age of 65.

School job scam and the future of university degree holders in West Bengal

By Harasankar Adhikari The school recruitment controversy in West Bengal has emerged as one of the most serious governance challenges in recent years, raising concerns about transparency, institutional accountability, and the broader impact on society. Allegations that school jobs were obtained through irregular means have led to prolonged legal scrutiny, involving both the Calcutta High Court and the Supreme Court of India. In one instance, a panel for high school teacher recruitment was ultimately cancelled after several years of service, following extended judicial proceedings and debate.
