Recent research indicates that pigs may act as a transmission vehicle for a strain of the hepatitis E virus (HEV) commonly found in rats, known as Rocahepevirus ratti, or rat HEV.
Role of Pigs in Transmission
HEV Reservoir: Pigs naturally carry hepatitis E virus (HEV), particularly strains that can infect humans.
Transmission via Pork: Humans can contract HEV by consuming raw or undercooked pork from infected pigs.
Environmental Contamination: Infected pigs shed HEV in faeces, contaminating the environment and water sources, potentially spreading the virus to humans.
Poor sanitation in pig farms facilitates HEV transmission between pigs and increases the risk of human infection through the food chain.
Cross-Species Transmission: Pigs may also act as intermediaries for rat HEV, transmitting the virus from rats to humans in farm environments.
AboutHepatitis E Virus (HEV):
Hepatitis E is caused by the Hepatitis E Virus (HEV), which is a positive-sense, single-stranded, non-enveloped RNA virus.
HEV is classified under the family Hepeviridae, genus Orthohepevirus.
It was first identified during an outbreak among Soviet soldiers in Afghanistan in 1983.
The earliest well-documented HEV epidemic occurred in New Delhi, India, in 1955, retrospectively identified as HEV.
Transmission:
The primary route of transmission is fecal-oral, especially through contaminated water and food.
Zoonotic transmission is possible with genotypes 3 and 4, commonly spread through undercooked meat or direct animal contact.
Symptoms:
Jaundice, nausea, fatigue, and elevated liver enzymes.
Severe cases can lead to liver failure, especially in pregnant women and immunocompromised individuals.
Prevention and Cure:
A vaccine, HEV 239, is approved for use in China, but no vaccine is widely available or approved in most countries, including the United States.
There is no specific antiviral treatment for acute HEV.
Prevention relies on improved sanitation, safe drinking water, and proper food handling.

A study conducted at Moorea, French Polynesia, has revealed that the network of dead coral skeletons left behind by bleaching events prevents reefs from regenerating.
About Corals
Corals are marine invertebrates made up of genetically identical organisms called polyps.
Polyps have a mutualistic relationship with microscopic algae called zooxanthellae that live within their tissues.
Zooxanthellae perform photosynthesis, providing the corals with carbohydrates, while the corals offer compounds needed for photosynthesis.
Corals have calcium carbonate skeletons, which help in building the reef structure.
Thousands of polyps combine to form coral colonies, which multiply and grow over time.
Coral reefs are underwater ecosystems formed by the accumulation of calcium carbonate skeletons from corals.
Known as the “rainforests of the seas”, they provide habitat and protection for a wide variety of marine life.
Coral reefs are built by both hard and soft corals and grow over time as more corals attach to the reef structure.
They are the largest living structures on the planet, vital for marine biodiversity.
Challenges due to Dead Corals
Shelter for Seaweed: Dead coral skeletons create a complex structure that offers protection to macroalgae (seaweed) from herbivores. This allows seaweed to colonize the reef quickly, outcompeting young coral.
Impeded Herbivory: The complex landscape of dead corals prevents herbivores, which normally graze on algae, from accessing the macroalgae effectively. This leads to unchecked algae growth.
Increased Competition: Macroalgae grow faster and reproduce more frequently than coral, leading to increased competition for space, light, and nutrients, which further inhibits young coral from settling and growing.
Annual Coral Reproduction: Coral typically spawns only once a year, while algae reproduce continuously. This gives algae a competitive advantage in newly available spaces left by dead coral skeletons.
Altered Ecosystem Balance: The presence of dead coral shifts the balance between herbivores, algae, and coral, making it difficult for the reef to regenerate naturally.
Conditions for Reef Regeneration
Flat Substrate: After events like cyclones, which remove coral but leave behind a flat surface, reefs tend to recover more easily, as young coral can settle and regrow without much competition from macroalgae.
Herbivore Activity: Active herbivory is crucial for reef recovery, as herbivores control the growth of macroalgae, allowing space for coral recruits to settle and thrive.
Clear Space for Coral Recruits: To regenerate effectively, coral needs open space free from excessive algae. Removing dead coral skeletons might help create these conditions.
Frequent Disturbances: Coral reefs are better adapted to recover from frequent but non-lethal disturbances like storms, which scrape off coral and allow for fresh regrowth, compared to bleaching events, which leave the dead coral structure intact.
Water Quality and Temperature: Coral recovery depends on optimal water conditions, including the absence of pollutants and suitable temperatures.
PYQ:
[2018] Consider the following statements
Most of the world’s coral reefs are in tropical waters.
More than one-third of the world’s coral reefs are located in the territories of Australia, Indonesia and Philippines.
Coral reefs host far more number of animal phyla than those hosted by tropical rainforests.

Mentor’s Comment: Agroforestry plays a crucial role in enhancing the resilience of Indian agriculture through various mechanisms. By integrating trees with crops and livestock, agroforestry provides farmers with multiple income streams, reducing dependence on single crops and mitigating the impact of market fluctuations. The integration of trees provides shade and wind protection, making agricultural systems more resilient to extreme weather events such as droughts and floods. This adaptability is vital for farmers facing unpredictable climate patterns. In today’s editorial, we will focus on Indian-centric issues.
_
Let’s learn!
Why in the News?
Recent studies indicate that with the right policies and financial support, India could sequester an additional 2.5 billion tons of CO2 equivalent by 2030 in the agroforestry sector.
Currently, agro-forestry represents 8.65% of India’s land and contributes 19.3% of its carbon stocks, playing a vital role in both environmental sustainability and economic growth.
India is poised to increase agroforestry area from 28.4 million hectares to 53 million hectares by 2050.
CASE STUDY of UP:
• In Uttar Pradesh, a new agroforestry project aims to connect local farming with the global carbon credit market, potentially generating 4.5 million carbon credits valued at around Rs 230 crore. • This initiative is part of a broader strategy to enhance rural incomes while increasing the state’s green cover from 9.23% to 15% by 2027. • The success of these projects hinges on adapting carbon finance standards to better suit India’s unique agricultural landscape, which could unlock further opportunities for smallholder farmers.
How does the ‘Polluter Pays Principle’apply to carbon credits in agro-forestry?
The Polluter Pays Principle (PPP) is a fundamental concept in environmental economics that holds polluters responsible for the costs associated with their environmental impact.
Responsibility for Emissions: Industries that emit greenhouse gases are required to compensate for their emissions by purchasing carbon credits.
Each credit represents one ton of CO2 or its equivalent that has been sequestered or reduced, which creates a financial incentive for these industries to invest in carbon offset projects like agroforestry.
Market Dynamics: The carbon credit market operates on the principle that companies must buy credits to offset their emissions, thus internalizing the external costs of pollution.
What are the present issues for the Indian Market?
In carbon finance, “common practice” assesses the projects that have additional regional activities (larger areas), meaning they are disqualified from earning carbon credits if they don’t provide additional environmental benefits.
For example, standards like Verra’s VCS and Gold’s current definitions reflect large-scale agricultural practices in regions like Latin America and the U.S., overlooking India’s context of small, fragmented landholdings.
However, in India, approximately 86.1% of farmers have less than two hectares, often practicing agroforestry in a non-systematic manner, which may not meet the additionality criteria. Many Indian farmers are excluded from ARR carbon finance projects due to this.
Why is there a need for an India-centric approach?
Revising standards to fit India’s fragmented small-holder model could allow more farmers to participate in carbon finance projects.
Enhanced Income Streams: Integrating agroforestry with Afforestation, Reforestation, and Revegetation (ARR) initiatives provides farmers with additional income through carbon credits, diversifying their revenue sources.
This integration helps tackle issues such as low productivity, small land holdings, dependence on monsoons, and environmental degradation by promoting sustainable land management practices.
Soil and Ecosystem Health: Agro-forestry practices improve soil quality, enhance water retention, and mitigate erosion, contributing to overall ecosystem health and agricultural productivity.
Biodiversity Conservation: The integration encourages greater biodiversity by incorporating various tree species alongside crops, promoting ecological balance within agricultural landscapes.
Alignment with National Goals: The integration supports India’s climate goals and commitments under international agreements by increasing carbon sequestration potential and enhancing green cover.
Long-Term Sustainability: By establishing a systematic approach to agroforestry through ARR initiatives, farmers can achieve sustainable agricultural practices that ensure long-term productivity and environmental health.
Way Forward:
TheEnergy and Resources Institute (TERI)has launched 19 ARR projects across seven states in India, benefiting over 56,600 farmers.
To scale these initiatives, international carbon finance platforms must revise their standards to align with the realities of Indian agriculture.
A systematic approach to agro-forestry supported by carbon finance can help farmers diversify their income, making them more resilient to climate variability.
This year marks the beginning of the centenary of the “Self-Respect Movement”, a transformative movement with a unique mission to empower individuals and communities to challenge and dismantle the oppressive hierarchical structures that had subjugated them.
What is the significance of the Self-Respect Movement?
Empowerment Against Hierarchical Structures: The Self-Respect Movement, founded by Periyar in 1925, aimed to dismantle the caste-based hierarchy that oppressed lower castes, especially in the Madras Presidency.
Social Reform Beyond Political Representation: The movement went beyond advocating for communal representation, focusing on equal rights for women, caste abolition, and the upliftment of the depressed classes.
It introduced radical reforms like self-respecting marriages and supported women’s rights such as property ownership, divorce, and widow remarriage.
Kudi Arasu’s Role: The Tamil weekly, Kudi Arasu (The Republic), served as a platform to spread Periyar’s critiques of Brahminism and the caste hierarchy, expanding the reach of the Self-Respect Movement.
Federalism and Political Autonomy: Periyar and the movement contributed to the evolution of federalism in India by advocating for regional autonomy and opposing the dominance of elite caste groups in politics.
How can the principles of the self-respect movement be sustained and promoted?
Adaptation to Contemporary Issues: The movement must address modern complexities like the intersectionality of caste with class, religion, gender, and sexuality. Expanding the movement’s scope to include LGBTQIA+ rights and evolving gender norms will keep it relevant.
Counter-fack news on social media: Active communication with younger generations, particularly in countering right-wing narratives and caste biases on social media, is vital for promoting the movement’s ideals of equality and rationalism.
Reframing Social Justice in a Global Context: Sustaining the Self-Respect Movement’s legacy requires integrating its principles with global discussions on social justice, identity politics, and human rights.
Advocacy for Policy Reforms: Continuous advocacy for policies that address caste and gender inequalities, such as reservations and legal protection for self-respect marriages, can strengthen the movement’s impact.
What challenges does the self-respect movement face in the current socio-political climate?
Cultural Homogenisation: The rise of Hindutva and right-wing ideologies seeks to homogenise India’s diverse cultures, underminingregional, linguistic, caste, and gender identities that the movement has historically sought to protect.
Evolving Caste Dynamics: While traditional caste practices may have declined in some areas, caste-based discrimination persists subtly in other forms, which the movement must continue to confront.
Digital Misinformation: The rise of social media has led to the spread of falsehoods that reinforce caste and group prejudices. The movement must actively engage in digital spaces to counter these narratives.
Caste-based politics: In states like Bihar and Uttar Pradesh, many regional political parties engage in caste-based politics, which indirectly obstructs the principles and application of the Self-Respect Movement.
Way forward:
Promote Inclusive Policy Reforms: The Indian government should enhance policies that target caste and gender inequalities, such as expanding legal protections for self-respect marriages and enforcing anti-discrimination laws, while ensuring marginalized communities have equitable access to resources and opportunities.
Strengthen Digital Literacy and Anti-Misinformation Efforts: The government should initiate programs to combat digital misinformation, particularly caste-based narratives, by promoting digital literacy, fact-checking, and inclusive content on social media platforms to foster equality and social harmony.
India’s land governance system is a tangled web of laws that have significantly impeded the nation’s economic and social progress for many years.
What are the limitations of digitisation in land law reform?
Failure to Address Legal Complexities: Digitisation alone does not resolve the underlying conflicts in land laws, such as unclear titles, insecure tenure, and legal ambiguities around land ownership and transfers.
Outdated Records: Even digitised land records may remain outdated or inaccurate, undermining the reliability of property titles and failing to improve access to formal credit.
Ineffectiveness in Fragmented Land Markets: Digitisation does not solve the issue of land fragmentation, which reduces agricultural productivity and hampers investment.
Limited Impact on Tenancy and Leasing Laws: Digitisation does not address restrictions on land leasing or tenancy, leaving land markets inefficient and informal.
Overreliance on Administrative Procedures: The complexities of legal and administrative frameworks still hinder land ownership, transfers, and use, despite digitisation efforts.
Political Exemptions from Judicial Review: The exclusion of land laws from judicial scrutiny through the Ninth Schedule limits accountability and the ability to challenge unjust political or administrative actions.
How do socio-political factors influence the effectiveness of digitisation efforts?
Political Resistance: Local and state-level political interests may resist changes to land laws that could undermine entrenched power structures or vested interests, impeding the effectiveness of digitisation efforts.
Rent-Seeking Behavior: Complex land laws and administrative procedures encourage rent-seeking, making digitisation ineffective without legal reforms that simplify regulations.
Cultural Norms and Gender Disparities: Socio-political dynamics, especially regarding gender and caste, influence land ownership patterns, limiting the impact of digitisation in addressing social inequalities.
State Variability: Differences in state capacity, resources, and political will lead to uneven adoption and success of digitisation efforts across India.
Lack of Integration in Subsidy Targeting: Social and political factors, such as inefficient targeting of subsidies (e.g., fertiliser subsidies not linked to land records), limit the impact of digitisation on equitable resource distribution.
Exclusion from Judicial Review: The Ninth Schedule’s protection of land laws from judicial review allows political decisions to go unchallenged, reducing the long-term effectiveness of digitisation reforms.
What additional measures are necessary for effective land law reform? (Way forward)
Comprehensive Legal Reforms: Overhaul conflicting land laws to ensure clarity, secure property titles, and strengthen property rights.
Tenancy and Leasing Reforms: Modernise and liberalise tenancy laws to formalise leasing arrangements and reduce the risk of expropriation.
Land Use Flexibility: Reforms allowing easier conversion of land use between agricultural, industrial, and residential sectors to ensure optimal land utilisation.
Land Consolidation Policies: Facilitate land consolidation to improve agricultural productivity and attract investment by reducing fragmentation.
Gender Equality in Land Ownership: Strengthen laws ensuring equal land and property rights for women, addressing gender-based inequalities in land ownership.
Judicial Oversight: Allow land laws to be subject to judicial review, ensuring fairness and protecting against arbitrary political and administrative decisions.
