  • Adventure tourism involves risk, physical exertion, and natural terrains; includes mountaineering, trekking, rafting, skiing; recognised globally as a fast-growing, high-spending, niche tourism segment.
  • Indian Himalayas stretch ~2,500 km across northern India; Uttarakhand’s Garhwal–Kumaon Himalayas host major glaciers, steep relief, and technically demanding peaks attractive to elite climbers.
  • Earlier, many peaks remained restricted due to ecological fragility, border proximity, and complex permits, limiting India’s share in global mountaineering compared to more open regimes like Nepal.
  • Tourism is a State subject, but forests and wildlife fall in Concurrent List, requiring coordination between Union and State governments while permitting mountaineering in ecologically sensitive landscapes.
  • Activities near protected areas must comply with Forest (Conservation) Act, 1980 and Wildlife (Protection) Act, 1972, ensuring expeditions do not degrade notified ecosystems or wildlife habitats.
  • Article 48A and Article 51A(g) impose duties on State and citizens to protect environment, requiring mountaineering policies to integrate conservation safeguards and sustainable use principles.
  • Shifting financial burden from climbers to government reduces bureaucratic friction, potentially increasing participation, but demands strong regulatory oversight to prevent misuse and ensure environmental compliance.
  • The digital mountaineering permission portal improves transparency, real-time tracking, and data availability, enabling better regulation, safety monitoring, and evidence-based policy adjustments.
  • Effective implementation requires coordination among Tourism, Forest, Disaster Management authorities, ITBP, and district administrations, especially for rescue operations and environmental monitoring.
  • Adventure tourists spend significantly higher per capita, supporting guides, porters, transporters, equipment rentals, and homestays, creating strong local economic multiplier effects in remote mountain districts.
  • Tourism contributes roughly 7–8% of Uttarakhands GSDP (estimates), and diversification into mountaineering reduces overdependence on seasonal pilgrimage tourism like Char Dham.
  • Opening premium peaks can position Uttarakhand as a high-value, low-volume destination, aligning with sustainable tourism models prioritising quality revenue over mass footfall.
  • Mountaineering promotion can empower local youth with skills, certifications, and employment, reducing distress migration from hill districts and strengthening local mountain economies.
  • Ethical concerns include ensuring fair wages, insurance, and safety protections for porters and guides who face disproportionate risks during high-altitude expeditions.
  • Some Himalayan peaks hold cultural and spiritual significance, requiring sensitive tourism models that respect local beliefs and traditional relationships with sacred landscapes.
  • Himalayas are geologically young, tectonically active mountains, highly prone to landslides, earthquakes, avalanches, and flash floods, making large-scale mountaineering inherently risky.
  • Expedition-related waste, campsite pressure, and human disturbance can degrade fragile alpine ecosystems with slow natural regeneration rates and low carrying capacity.
  • Past disasters like 2013 Kedarnath floods and 2021 Rishi Ganga flood highlight cumulative risks from climate change, glacial instability, and unplanned human activity.
  • India hosts ~9,500+ glaciers, many concentrated in Uttarakhand, making it hydrologically crucial but also highly vulnerable to climate-induced glacial retreat and hazards.
  • Global adventure tourism market exceeds $300 billion, growing around 15–20% annually, indicating strong demand for regulated, high-quality mountain tourism destinations.
  • High-altitude ecosystems exhibit low resilience and slow recovery, meaning even small-scale disturbances can have long-lasting ecological impacts.
  • Weak enforcement of waste-return rules and Leave No Trace principles risks accumulation of non-biodegradable waste in pristine high-altitude zones.
  • Limited high-altitude rescue infrastructure, weather forecasting, and trauma care reduce safety margins for climbers and local support staff.
  • Fee waivers may reduce dedicated conservation funds unless government ensures compensatory environmental financing mechanisms.
  • Risk of overtourism and route crowding if promotion outpaces regulation and carrying-capacity assessments.
  • Conduct scientific carrying-capacity studies for each peak and cap annual expeditions based on ecological and safety thresholds.
  • Implement strict waste buy-back policies, eco-certification, and environmental bonds refundable upon compliance with green norms.
  • Provide mandatory insurance, training, and safety standards for guides and porters, institutionalising mountain labour welfare.
  • Strengthen mountain rescue systems, early-warning networks, and climate monitoring, integrating technology and local knowledge.
  • Promote community-based eco-tourism models ensuring revenue sharing, local stewardship, and alignment with SDGs 8, 12, 13, and 15.


  • Union Budget announced turtle trails along nesting coasts of Odisha, Karnataka, Kerala, triggering concerns among conservationists about tourism pressure on ecologically sensitive marine turtle nesting habitats.

  • Antimicrobial resistance (AMR) occurs when microbes evolve mechanisms to survive drugs, making infections harder to treat and increasing morbidity, mortality, and healthcare costs globally.
  • AMR is driven by antibiotic misuse in humans, livestock, and agriculture, plus pharmaceutical effluents and poor wastewater treatment infrastructure, especially in densely populated developing countries.
  • Sewage surveillance captures community-level signals from households, hospitals, farms, and industries, offering early-warning insights into antibiotic use and resistance trends.
  • The dipstick works like a rapid diagnostic test, detecting amplified resistance genes from sewage DNA using PCR-based amplification and visible colour-band readouts.
  • Each dipstick detects 16 resistance genes and provides results within two hours, enabling time-efficient, field-friendly surveillance without advanced laboratory infrastructure.
  • The platform is upgradeable within three days if new resistance genes emerge globally, ensuring adaptability to evolving microbial threats.
  • India is recognised as a global AMR hotspot by WHO, with high infectious disease burden and widespread antibiotic access without prescriptions.
  • AMR threatens procedures like surgeries, chemotherapy, and organ transplants, where effective antibiotics are critical for infection prevention.
  • Low-cost surveillance supports India’s National Action Plan on AMR (NAP-AMR) goals on monitoring and containment.
  • AMR could cause 10 million deaths annually by 2050 globally and reduce global GDP by 2–3.5%, according to international estimates.
  • Affordable surveillance reduces long-term healthcare costs by enabling targeted interventions and rational antibiotic stewardship.
  • Low-cost diagnostics are vital for LMICs, where high-end genomic surveillance is financially unsustainable.
  • Sewage surveillance is considered ethically acceptable since it monitors communities anonymously without targeting individuals, avoiding privacy and consent concerns.
  • Helps protect vulnerable populations who suffer disproportionately from drug-resistant infections due to limited healthcare access.
  • Encourages a One Health approach, integrating human, animal, and environmental health.
  • Researchers analysed sewage from 381 locations across Assam, Haryana, Jharkhand, UP, Uttarakhand, and West Bengal, confirming widespread antibiotic residues and resistance genes.
  • India has some of the highest antibiotic consumption rates globally, increasing selection pressure for resistant microbes.
  • Only a fraction of wastewater in India undergoes effective treatment, facilitating AMR spread.
  • Detection of a gene signals possibility of resistance, not presence of a live pathogenic organism; genes alone do not cause disease.
  • AMR expression varies by gene combinations and ecological context, requiring cautious interpretation.
  • Dipsticks complement but do not replace culture-based and genomic surveillance.
  • Integrate dipstick surveillance into routine urban wastewater monitoring under public health and Jal Shakti frameworks.
  • Link results to antibiotic stewardship programmes and regulation of pharmaceutical effluents.
  • Expand AMR labs and genomic surveillance for confirmatory analysis.
  • Strengthen wastewater treatment infrastructure under AMR containment strategy.
  • Promote global data sharing aligned with WHO Global AMR Surveillance System (GLASS).

  • Reports show 40 land productivity losses, 25 house damages, 30 school disruptions, indicating deep social impacts beyond economic loss.
  • Carefully designed eco-tourism can diversify livelihoods, reducing dependence on climate-sensitive agriculture and fisheries.
  • Community-based tourism can generate income for boat operators, guides, homestays, handicrafts, and local services, spreading climate-risk.
  • Mangrove and wildlife tourism can incentivise conservation-linked livelihoods, aligning ecology and economy.
  • Sundarbans’ carrying capacity is unassessed, making large-scale tourism scientifically risky for fragile mangrove and delta ecosystems.
  • Mangroves act as natural coastal buffers, and ecosystem disturbance can weaken storm protection functions.
  • Illegal tourism already violates CRZ norms and NGT orders, reflecting weak regulatory enforcement.
  • Comparing Sundarbans with Ranthambore is ecologically flawed; Sundarbans is riverine, dispersed, and sighting-based tourism is inherently uncertain.
  • Ranthambore supports safari tourism on firm terrain, whereas Sundarbans relies on boat-based, low-density access, limiting scale.
  • Tourism models must reflect ecosystem type, hazard exposure, and settlement density.
  • Sundarbans hold over 42% of Indias mangrove cover, yet West Bengal reportedly receives relatively lower central mangrove-conservation funding.
  • Expansion as a major tiger reserve indicates conservation success but also requires balancing tourism with habitat protection.
  • Climate adaptation finance and conservation funding remain critical.
  • Risk of over-commercialisation in a fragile delta could damage biodiversity and increase disaster exposure.
  • Tourism income may be seasonal and unevenly distributed, not a complete substitute for primary livelihoods.
  • Infrastructure expansion can increase ecological footprint and disaster vulnerability.
  • Conduct scientific carrying-capacity and vulnerability assessments before scaling tourism.
