Core Points
Misinformation and Scientific Reasoning
- Debate around HPV vaccination illustrates the difference between rational doubt and selective use of information to promote conspiracy theories.
- Public health decisions should rely on evidence rather than cherry-picked data.
Global Scientific Consensus
- Major scientific bodies such as ICMR and CDC recommend HPV vaccination.
- Around 160 countries, including most high-income nations, have adopted HPV vaccination programmes.
- There is near-universal consensus on vaccinating women, although some countries also vaccinate men.
HPV and Cancer Risk
- HPV causes the majority of cervical cancer cases.
- It also contributes to anal, oropharyngeal, vulvar, vaginal, and penile cancers.
- Although men can develop HPV-related cancers, the risk is highest for women.
- India has one of the highest cervical cancer burdens globally.
Evidence on Vaccine Effectiveness
- Vaccines such as Gardasil, used in India’s rollout, have shown effectiveness in large clinical trials.
- Real-world vaccination programmes involving tens of millions of adolescents across multiple countries have been conducted.
- Population-scale interventions have shown:
- Significant reduction in HPV infections.
- Decline in precancerous lesions.
- Reduction in cervical cancer where sufficient time has passed.
Concerns About Safety
- Concerns were raised after a 2009 Indian study reported deaths among vaccinated participants.
- Investigations found deficiencies in the trial but no evidence linking vaccination to the deaths.
- Causes of death included poisoning, drowning, and cerebral malaria.
- In large trials, adverse events unrelated to the intervention may occur.
Scientific Evaluation of Adverse Events
- Vaccine safety is assessed by comparing event rates in vaccinated groups with control groups.
- Large trials and post-licensure surveillance studies have monitored HPV vaccine safety.
- Except for syncope (temporary fainting), which is common after vaccinations among adolescents, no adverse events have occurred at higher-than-expected rates.
Monitoring and Policy Response
- Rare adverse event reports are investigated seriously.
- Japan temporarily suspended HPV vaccination after reports of pain or numbness.
- Investigations later found no causal link with the vaccine, and vaccination resumed in 2021.
- Effective monitoring systems for adverse effects remain important.
Ethical and Social Concerns
- Some concerns relate to vaccinating young girls against a sexually transmitted infection.
- The HPV vaccination programme is voluntary, and parents can choose whether to vaccinate their children.
- Vaccination is recommended for ages 9–14 because preventive vaccines work best before exposure risk increases.
- Early vaccination aims to maximise protection, not to endorse early sexual activity.
Public Health Significance
- HPV vaccination offers an opportunity to prevent thousands of future cancers among women in India.
- Delays in vaccination may lead to avoidable health harm.
- Constructive scepticism can strengthen science, but manufactured doubt can weaken public health efforts.
Key Details
- HPV is responsible for the majority of cervical cancers and contributes to several other cancers.
- Around 160 countries recommend HPV vaccination.
- Vaccine used in India’s rollout: Gardasil.
- Major clinical trials referenced: Future I, Future II, Patricia.
- 2009 Indian study reported deaths among vaccinated participants but found no causal link to the vaccine.
- Causes of deaths included poisoning, drowning, and cerebral malaria.
- Japan temporarily halted HPV vaccination due to adverse event reports and resumed vaccination in 2021 after investigations.
- Recommended vaccination age group: 9–14 years.
Data Gaps In India’s Social And Linguistic Diversity
Context
The article highlights the absence of reliable data on several aspects of India’s social composition, particularly Denotified and Nomadic Tribes (DNTs) and linguistic diversity. It argues that existing census practices and recent policy approaches fail to adequately capture the country’s social and cultural diversity.
Source: We speak in many tongues. That is not something that should scare us, The Indian Express
Core Points
Uncertainty About Social Composition
- India does not have a clear answer on how many caste communities exist or how they historically emerged.
- Similar uncertainty exists regarding the number of Other Backward Classes (OBCs) in the country.
- Even less attention has been given to determining the number of Denotified and Nomadic Tribes (DNTs).
Historical Background of Denotified and Nomadic Tribes
- Many DNT communities were classified as “criminal tribes” under the Criminal Tribes Act (CTA) of 1871.
- These communities were denotified in 1952 after Independence.
- After denotification, they were placed under various categories such as SC, ST, or General lists.
- India does not have an official count of the number of DNT communities or their population.
- The CTA was enacted in the same year as the first Census in India, highlighting a historical irony.
Lack of Comprehensive Linguistic Data
- India does not have a precise list of languages spoken or their scripts.
- George Abraham Grierson proposed a linguistic survey in 1886.
- The colonial government began the survey eight years later, which continued for about three decades.
- Grierson’s survey recorded 179 languages and 544 dialects.
- The geographical map of India at the time differed from the present one.
Linguistic Diversity and Census Data
- The Constitution describes India as a Union of States, many of which are organised as linguistic states.
- Despite this, there has been no official Linguistic Survey since Independence.
- The country relies mainly on Census data for language-related information.
Changing Language Data in Census
- 1961 Census recorded 1,652 mother tongues.
- 1971 Census reported 108 languages, with another category called “others”.
- 2011 Census listed 1,369 mother tongues and 121 languages.
- There has been no parliamentary discussion on why 283 mother tongues disappeared between 1961 and 2011.
Issues with Upcoming Census
- The delayed 2021 Census is expected to be completed by 2027.
- Proposed questions do not include data on OBCs or DNTs.
- A rule states that languages with fewer than 10,000 speakers will not be published in Census reports.
- The author argues that this rule has no scientific basis, as linguists do not define languages based on minimum speaker numbers.
- The Census distinction between “mother tongue” and “language” is considered illogical.
Debate on Language Classification
- Since the late 18th century, languages have been classified into linguistic families.
- Major language families in India include:
- Indo-Aryan
- Dravidian
- Sino-Tibetan
- Austro-Asiatic
- The Bharatiya Bhasha Samiti is promoting the idea that these languages belong to a single “Bharat bhasha parivar”.
- This theory proposes a common origin predating the Indus Valley civilisation with Sanskrit as the primary source.
- The author argues that this idea lacks scientific validity.
Broader Implication
- Current census practices and linguistic interpretations may not adequately capture India’s social and cultural diversity.
- Accurate understanding of social groups and linguistic diversity requires more reliable and scientifically grounded data collection.
Key Details
- Criminal Tribes Act (1871): classified certain communities as criminal tribes; they were denotified in 1952.
- No official count exists for Denotified and Nomadic Tribes (DNTs) or their population.
- Grierson’s Linguistic Survey recorded 179 languages and 544 dialects.
- 1961 Census recorded 1,652 mother tongues.
- 1971 Census reported 108 languages plus “others”.
- 2011 Census listed 1,369 mother tongues and 121 languages.
- In the upcoming Census, languages with fewer than 10,000 speakers will not be published in reports.
- Major language families in India include Indo-Aryan, Dravidian, Sino-Tibetan, and Austro-Asiatic.
Pakistan’s Defence Export Push And Strategic Implications For India
Context
Pakistan’s recent defence export initiatives, including arms deals with Libya and negotiations with Sudan, indicate its attempt to expand its role as a regional security provider. These developments have strategic implications for India, particularly in the Gulf region and the wider Global South.

Core Points
Emerging Strategic Concern for India
- Pakistan’s expanding defence exports and security partnerships may increase its strategic influence in the Gulf and neighbouring regions.
- This development could challenge India’s position in a region where India currently has strong economic engagement.
- If Pakistan consolidates its role as a regional defence supplier, it could enhance its geopolitical leverage vis-à-vis India.
Potential Impact on Regional Geopolitics
- Pakistan’s defence cooperation with Gulf monarchies may strengthen its political and security partnerships in West Asia.
- Greater security dependence of Gulf countries on Pakistan could allow Islamabad to expand its regional outreach and strategic presence.
- Such developments may help Pakistan project itself as a security provider beyond South Asia.
Implications for India’s Strategic Environment
- Pakistan’s growing defence engagement in the Gulf may affect regional power dynamics.
- Expanded defence partnerships may also help Pakistan improve its international image despite previous allegations related to terrorism and financial irregularities.
- These developments could potentially embolden Pakistan’s strategic posture towards India.
India’s Current Position in Defence Exports
- India’s defence exports have grown significantly, reaching $2.8 billion in 2024–25.
- Despite improvements, India still ranks low among the world’s top defence exporters.
- India remains the second-largest arms importer globally, highlighting a gap between domestic production and export performance.
Need to Strengthen India’s Defence Export Strategy
- India should prioritise defence exports as a strategic and economic tool.
- Defence exports can generate both financial benefits and geopolitical influence.
- India should particularly focus on partner countries in its neighbourhood and the Global South.
Leveraging Economic and Diplomatic Tools
- As one of the world’s largest crude oil importers, India could use its energy trade relationships to encourage defence procurement from Indian suppliers.
- India’s development assistance and credit lines to other countries can also support defence export agreements.
Institutional Measures for Export Promotion
- Establish a dedicated defence export promotion organisation involving:
- Public and private defence manufacturers
- Relevant ministries
- Technical experts including those from IT and Artificial Intelligence
- Financial institutions
- Such an organisation should actively market Indian defence products globally and participate in international defence exhibitions.
- It should also have greater operational autonomy to negotiate and finalise defence deals.
Strategic Objective
- India should aim to reduce the gap between its position as a major arms importer and its relatively low ranking as a defence exporter.
- Strengthening defence exports can help enhance India’s strategic influence and economic returns.
Key Details
- India’s defence exports (2024–25) are about $2.8 billion.
- India is the second-largest arms importer globally.
- Pakistan’s defence production is estimated at about $7 billion annually, while India’s is about $18 billion.
- Pakistan’s recent defence deals and negotiations could reach approximately $13 billion in value.
Managing Religious Tourism In Forests And Protected Areas
Context
Religious sites such as groves, caves and shrines are often located within or near India’s forests and protected areas. Increasing pilgrimage-related tourism and infrastructure are creating ecological pressures, raising policy challenges on balancing faith practices with conservation and community rights.
Source: Aligning religious tourism with ecology, The Hindu
Core Points
Faith–Ecology Interface in India
- India’s religious geography often overlaps with ecologically sensitive forest landscapes.
- Sacred groves, caves, shrines and pilgrimage routes are frequently located within or near protected areas.
- Traditionally, belief systems regulated access and behaviour, allowing coexistence between communities and nature.
Emerging Environmental Pressures
- Rising visitor numbers and commercialisation of pilgrimage routes are placing stress on forest ecosystems.
- Earlier seasonal, community-based rituals are increasingly turning into mass tourism.
- Infrastructure development linked to pilgrimage can exceed the ecological carrying capacity of fragile habitats.
Policy Flashpoint: Religious Structures in Protected Areas
- The issue gained attention during deliberations of the Standing Committee of the National Board for Wildlife (SCNBWL).
- A proposal to expand a religious establishment inside a sanctuary in Gujarat was initially approved but later withdrawn.
- Concerns arose that approving such projects could set a precedent for diversion of protected areas for religious institutions.
- The Environment Minister suggested framing a Standard Operating Procedure (SOP) for proposals involving religious sites in forests.
Legal Framework Governing Forest Areas
- Under the Forest (Conservation) Act, 1980, construction or expansion on forest land after 1980 is generally treated as encroachment.
- The Wildlife (Protection) Act, 1972 and National Tiger Conservation Authority (NTCA) norms allow only limited interventions.
- Such interventions are typically justified only to manage pressures or mitigate ecological conflict.
- Unregulated construction can fragment habitats, increase human–wildlife conflict, and weaken protected areas.
Rights of Forest-Dwelling Communities
- Conservation policies must consider the social and cultural dimensions of forest landscapes.
- Many sacred natural sites are managed and protected by local communities.
- Sacred groves often function as biodiversity refuges due to restrictions rooted in belief systems.
- The Forest Rights Act (2006) mandates recognition of the rights of Scheduled Tribes and other traditional forest dwellers.
- Any restriction or regulation affecting traditional practices must follow formal recognition of these rights.
Need for a Balanced Policy Approach
- A blanket ban on religious activity in forests would be neither culturally sensitive nor constitutionally appropriate.
- At the same time, allowing new constructions or expansions under religious grounds may create harmful precedents.
- Policy must therefore balance faith practices, ecological protection and community rights.
Green Pilgrimage Model
- In 2023, the Ashoka Trust for Ecology and the Environment (ATREE) and World Wildlife Fund (WWF) proposed guidelines for religious tourism in tiger reserves.
- Based on field experience in Kalakad–Mundanthurai, Ranthambhore and Corbett, the guidelines suggest sustainable management practices.
Key Elements of Sustainable Religious Tourism
- No-expansion principle: No new construction or expansion in core forest areas.
- Recognition of long-standing religious sites that existed before protected area notification.
- Regulation through impact-based assessments.
- Caps on pilgrim numbers and restrictions such as bans on night traffic.
- Strict management of waste, sanitation and water use.
- Multi-stakeholder governance involving forest departments, temple authorities, local governments, communities and conservation groups.
Evidence from Pilot Implementation
- Measures such as restricting private vehicles, improving waste management through temple trusts, and engaging religious leaders have reduced:
- Roadkill incidents
- Plastic pollution
- Water contamination
- These measures allowed continued worship without displacing forest-dependent communities.
Policy Way Forward for India
- Adopt a zero-tolerance approach towards new encroachments in forests.
- Evaluate existing religious sites case-by-case with ecological safeguards.
- Ensure mandatory settlement of forest rights before regulatory actions.
- Implement green pilgrimage management models with continuous monitoring.
- Integrate ecological conservation with cultural continuity in governance of sacred natural sites.
Key Details
- SCNBWL deliberation: proposal to expand a religious establishment in a Gujarat sanctuary was withdrawn due to precedent concerns.
- Forest (Conservation) Act, 1980: post-1980 construction on forest land is generally treated as encroachment.
- Forest Rights Act, 2006: mandates recognition of rights of Scheduled Tribes and traditional forest dwellers.
- ATREE–WWF (2023) guidelines propose a green pilgrimage model for religious tourism in tiger reserves.
- Pilot implementations in Kalakad–Mundanthurai, Ranthambhore and Corbett showed reductions in ecological damage while maintaining access to worshippers.
