Five million visitors and rising: Scientists urge carrying capacity controls in Char Dham

By A Representative

A new scientific study published in Scientific Reports outlines a comprehensive strategy for developing sustainable tourism in the Char Dham circuit of Uttarakhand—Badrinath, Kedarnath, Gangotri, and Yamunotri—using advanced geospatial and socio-economic analysis. The research, conducted by Jagdish Chandra Kuniyal and colleagues from the Veer Chandra Singh Garhwali University of Horticulture and Forestry and the G. B. Pant National Institute of Himalayan Environment, stresses the urgent need for balancing religious tourism growth with environmental preservation in the fragile Himalayan ecosystem.

The paper notes that visitor numbers to the Char Dham have risen sharply—from around one million in the early 2000s to more than five million in 2023. Using multiple criteria decision analysis and GIS-based mapping, the team estimated that the sustainable daily tourist capacity should be limited to approximately 15,778 visitors at Badrinath, 13,111 at Kedarnath, 8,178 at Gangotri, and 6,160 at Yamunotri. The study correlates the rise in pilgrim inflows with increasing local income levels and infrastructure expansion but warns that unregulated growth threatens both biodiversity and community stability.

The researchers observed rapid glacial retreat in all four regions—most prominently at Gangotri, where ice loss averaged 22.36 metres per year between 2002 and 2020—along with temperature increases across pre-monsoon, monsoon, and post-monsoon seasons. These climatic shifts, compounded by flash floods and cloudbursts, have raised the frequency of disasters such as those witnessed in Kedarnath in 2013 and in other parts of Uttarakhand in 2025. The authors recommend setting up weather radars and early warning systems to protect lives and infrastructure.

The report highlights disparities among the districts that host the shrines: Rudraprayag, Uttarkashi, and Chamoli remain predominantly rural, with a large share of households below the poverty line. Despite the economic importance of the pilgrimage—estimated to contribute about USD 888 million annually and employ 50,000 people—the benefits have not translated evenly across communities. The study advocates community-based tourism models, homestays, and local handicraft promotion to ensure inclusive growth.

Kuniyal and colleagues propose a decentralized tourism framework that diverts pressure from core temple sites to surrounding “satellite destinations.” Suggested initiatives include developing mountaineering villages, promoting low-carbon transport, and introducing a mobile app to guide travellers toward eco-friendly accommodations and local products. The plan also encourages “Gham Tapo” or “basking in the sunshine” tourism during winter to extend the travel season and reduce overcrowding in the summer months.

Aligning with the United Nations Sustainable Development Goals, the paper urges policy measures such as restricting entry to Bharat Stage VI or electric vehicles, enforcing solid waste management through the polluter-pays principle, and empowering local tribes through eco-entrepreneurship. It also supports Uttarakhand’s Tourism Policy 2030 and national programs like Swadesh Darshan and PRASHAD, which prioritize sustainable infrastructure and heritage conservation.

The authors conclude that effective management of visitor numbers, improved monitoring of air and water quality, and digitalization of tourism services are essential for the long-term survival of the Himalayan pilgrimage routes. They caution that carrying capacity estimates should be dynamically updated as infrastructure and environmental conditions evolve, emphasizing that only a community-driven, scientifically informed approach can secure the future of the Char Dham as both a sacred and sustainable destination.

US-China truce temporary, larger trade war between two economies to continue

By Prabir Purkayastha The Trump-Xi meeting in Busan, South Korea on 30 October 2025 may have brought about a temporary relief in the US-China trade war. But unless we see the fine print of the agreement, it is difficult to assess whether this is a temporary truce or the beginning of a real rapprochement between the two nations. The jury is still out on that one and we will wait for a better understanding of what has really been achieved in Busan.

When growth shrinks people: Capitalism and the biological decline of the U.S. population

By Bhabani Shankar Nayak* Critically acclaimed Hungarian-American economic historian and distinguished scholar of economic anthropometric history, Prof. John Komlos (Professor Emeritus, University of Munich), who pioneered the study of the history of human height and weight, has published an article titled “The Decline in the Physical Stature of the U.S. Population Parallels the Diminution in the Rate of Increase in Life Expectancy” on October 31, 2025, in the forthcoming issue of Social Science & Medicine (SSM) – Population Health, Volume 32, December 2025. The findings of the article present a damning critique of the barbaric nature of capitalism and its detrimental impact on human health, highlighting that the average height of Americans began to decline during the era of free-market capitalism. The study draws on an analysis of 17 surveys from the National Health and Nutrition Examination Survey (NHANES), conducted by the U.S. Centers for Disease Control and Prevention (...

Justice for Zubeen Garg: Fans persist as investigations continue in India and Singapore

By Nava Thakuria* Even a month after the death of Assam’s cultural icon Zubeen Garg in Singapore under mysterious circumstances, thousands of his fans and admirers across eastern India continue their campaign for “ JusticeForZubeenGarg .” A large digital campaign has gained momentum, with over two million social media users from around the world demanding legal action against those allegedly responsible. Although the Assam government has set up a Special Investigation Team (SIT), which has arrested seven people, and a judicial commission headed by Justice Soumitra Saikia of the Gauhati High Court to oversee the probe, public pressure for justice remains strong.

Govt claims about 'revolutionary' rice varieties raise eyebrows: SC order reserved since Jan '24

By Rosamma Thomas * In a matter of grave importance for agriculture, public health awaits Supreme Court ruling, even as top Government of India bureaucrats stand accused of “willful and deliberate disobedience” of the top court. While a contempt petition filed by Aruna Rodrigues , lead petitioner in the Genetic Modification (GM) of crops matter remains pending in the Supreme Court since July 2025, the Union ministry of agriculture asserts that two home-grown gene edited rice varieties are of superior quality, and hold potential for “revolutionary changes in higher production, climate adaptability, and water conservation.” In May 2025, the Press Information Bureau released a press release stating that a “historic milestone” had been reached, under the leadership of Prime Minister Narendra Modi ; the new varieties, DRR Rice 100 (Kamla) and Pusa DST Rice 1 , the press release stated, offer both benefits – increased production and environmental conservation.

Banks, investors pour $52 billion into metallurgical coal expansion despite global climate pledges

By A Representative A new report by the German environmental and human rights NGO Urgewald has revealed that banks and institutional investors have poured nearly $52 billion into the expansion of metallurgical coal, or “met coal,” despite global commitments to phase out coal financing. Between 2022 and 2024, banks provided $21.96 billion in loans and underwriting to met coal developers, while investors held $30.23 billion in securities of companies expanding coal mining operations. The report, Still Burning: How Banks and Investors Fuel Met Coal Expansion, warns that loopholes in coal exit policies have allowed continued support for coal used in steelmaking — a sector responsible for about 11% of global CO₂ emissions.

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".

Bihar election: Democracy running away from people’s issues, politics thriving on fake agendas

By Sunil Kumar* Bihar’s political climate is currently heating up. Since the British colonial era, the state has remained trapped in a haze between labour struggles and uneven development, where basic issues such as unemployment, the plight of migrant workers, education, health, agrarian crisis, and corruption are constantly pushed to the background. In their place, absurd debates around “infiltrators,” “Operation Sindoor,” “Article 370,” “pistols,” “burqas,” and nicknames like “Pappu, Tappu, Appu” dominate the discourse.

Neglected dimension: Important linkages of social relationships, values to climate change

By Bharat Dogra A very important but neglected dimension of the efforts to resolve climate change and related serious environmental problems concerns the social values and relationships among people. To bring out the significance of this neglected aspect let us examine the response of two different types of societies. First, let us try to compare a society in which family and community ties are strong and close with another society where these are weak, where there is strong individualism and a very high number of single person households or units. In the first society there is more sharing of resources and facilities, so that this society tends to consume less (to meet needs such as housing and various gadgets). In addition there is much greater possibility in the first society to mobilize people for tasks like greening of community places or even household spaces. When it comes to tasks relating to climate change adaptation, it is the societies with close social relationships wh...
