New Seeds Bill 2025

  • 02 Dec 2025

In News:

The Union Government has introduced the Draft Seeds Bill, 2025 to modernise India’s seed regulatory system and replace the Seeds Act, 1966 and the Seeds (Control) Order, 1983. The proposed law seeks to address long-standing regulatory gaps, improve seed quality, curb the sale of spurious seeds, and align the legal framework with the evolving needs of Indian agriculture.

Why a new law was needed?

The Seeds Act, 1966 regulates only notified varieties, and registration of seeds has not been mandatory. Several categories such as green manure seeds, plantation crops, and certain commercial crops remained outside its ambit. Moreover, penalties under the old law were minimal a maximum of six months’ imprisonment and a fine of ?1,000 offering little deterrence in a rapidly expanding and commercialised seed market.

Concerns about the prevalence of substandard and fake seeds have grown in recent years. Between 2022 and 2025, authorities tested nearly six lakh seed samples, of which over 43,000 were found non-standard, prompting warnings, stop-sale orders, and legal cases. These trends highlighted the need for a stronger regulatory architecture.

India’s Seed Sector Context

India’s annual seed requirement for 2024–25 is estimated at about 48 lakh tonnes, while availability exceeds demand. The seed market is valued at roughly ?40,000 crore. Over 3,000 new crop varieties have been released in the past decade, with the public sector contributing the majority, though private participation is rising. This expansion has increased the need for quality assurance, traceability, and uniform standards.

Key Provisions of the Draft Seeds Bill, 2025

A central feature of the Bill is mandatory registration of all seed varieties before sale, except for traditional farmers’ varieties and seeds meant exclusively for export. New varieties must undergo Value for Cultivation and Use (VCU) testing across multiple locations to establish performance and suitability. Only seeds meeting prescribed standards of germination, genetic purity, and quality can enter the market.

The Bill also strengthens market regulation and traceability. Seed dealers must obtain registration from state authorities, and seed containers will carry QR codes linked to a central seed traceability portal to enable tracking across the supply chain. A Central Accreditation System is proposed to allow nationally accredited entities to operate across states, reducing multiple approvals.

Penalties are significantly enhanced. Minor violations attract monetary fines, while major offences such as selling spurious or unregistered seeds can lead to fines up to ?30 lakh and imprisonment up to three years. The government states that this will deter malpractice while protecting farmers.

The Bill affirms farmers’ rights to save, use, exchange, and sell farm-saved seeds, provided they are not marketed under a brand name. New central and state seed committees are envisaged to oversee implementation.

Concerns and Criticisms

Despite its reform intent, the Bill has drawn criticism from farmer groups and civil society. A major concern is the absence of a simple compensation mechanism for farmers affected by crop failure due to faulty seeds, leaving them dependent on lengthy legal processes.

Community seed keepers, such as Farmer Producer Organisations and traditional seed networks, may be treated as commercial entities, increasing compliance burdens. Critics argue that VCU testing norms may favouruniform hybrid varieties produced by large firms, potentially marginalisingindigenous and climate-resilient varieties. Digital compliance requirements, including QR tracking and online reporting, could also disadvantage small, resource-poor stakeholders.

Some experts also caution that recognition of foreign testing data may ease the entry of imported or genetically engineered seeds without robust domestic scrutiny.

Conclusion

The Draft Seeds Bill, 2025 represents a significant attempt to modernise India’s seed governance by emphasising quality control, traceability, and stricter penalties. However, its ultimate effectiveness will depend on balancing regulatory oversight with farmers’ rights, biodiversity conservation, and equitable access, ensuring that reform strengthens both productivity and sustainability in Indian agriculture.

Blue NDC Challenge at COP30

  • 22 Nov 2025

In News:

At COP30 in Belém, 17 countriesincluding France, Brazil, Belgium, Canada, and Singaporejoined the Blue NDC Challenge, signalling a global push to integrate ocean-based climate solutions into national climate plans under the Paris Agreement.

What is the Blue NDC Challenge?

  • A global voluntary initiative encouraging countries to embed ocean-related mitigation and adaptation actions into their Nationally Determined Contributions (NDCs).
  • Seeks to close the “ocean opportunity gap”, as oceansdespite covering ~70% of Earthreceive <1% of global climate finance and are underrepresented in mitigation plans.

Key Features

  • Expanded Membership: Coalition now includes 17 countries, with recent entrants such as Belgium, Canada, Indonesia and Singapore.
  • Ocean Taskforce: Supported by France and Brazil to assist governments in integrating ocean solutions into updated 2030 NDCs and translating commitments into policy and implementation.
  • Blue Package: A coordinated action framework across five Ocean Breakthrough sectors:
    1. Marine conservation
    2. Ocean (aquatic) food systems
    3. Offshore renewable energy
    4. Shipping decarbonisation
    5. Coastal tourism
  • Mitigation & Adaptation Focus:Recognises oceans’ potential to deliver up to ~35% of global emission reductions required for the 1.5°C target.
  • Blue Carbon Pathways: Integration of mangroves, seagrasses and salt marshes into national mitigation and adaptation strategies.

Why Oceans Matter for Climate Action

  • High Mitigation Potential: Offshore renewables, low-carbon shipping, and sustainable fisheries can significantly cut emissions.
  • Adaptation & Resilience: Coastal ecosystems protect shorelines, support livelihoods, and enhance food security.
  • Underfunded Sector: Ocean-related actions account for <1% of global climate finance, despite large co-benefits.

Global Context

  • A growing majority of countries now include ocean priorities in their NDCs, but adaptation dominates, while mitigation commitments remain limited.
  • Conservation and blue carbon are most common; shipping decarbonisation, offshore renewables, and low-carbon aquatic food systems are underrepresented.

Significance of the Initiative

  • Mainstreams the Ocean–Climate Nexus in national climate policy.
  • Mobilises Finance & Technical Support through coordinated action and partnerships.
  • Links Climate Action with Development: Job creation, clean energy expansion, biodiversity protection, and coastal community resilience.
  • Supports Synergy across global environmental frameworks (climate, biodiversity, sustainable development).

Belem Health Action Plan Launched at COP30

  • 19 Nov 2025

In News:

The 30th UN Climate Change Conference (COP30) held in Belém, Brazil, marked a major turning point in global climate governance by placing human health at the centre of climate adaptation discourse. The launch of the Belém Health Action Plan (BHAP) and the announcement of a $300 million commitment by over 35 global philanthropies under the Climate and Health Funders Coalition represent the first coordinated global effort to link climate adaptation finance with public health outcomes. This shift acknowledges that climate change is no longer an environmental issue alone but a multidimensional crisis with profound implications for human health, equity and development.

Climate-linked health risks have intensified sharply, as highlighted in the 2025 Lancet Countdown Report on Health and Climate Change. Heat-related deaths have increased by 23% since the 1990s, reaching 546,000 annually. Wildfire smoke contributed to 154,000 deaths in 2024, while dengue transmission potential has risen by 49% since the 1950s. According to Lancet findings, 3.3 billion people are at heightened health risk from rising temperatures, pollution, extreme rainfall, water scarcity, vector-borne diseases and extreme events. These impacts disproportionately affect vulnerable groups—children, pregnant women, elderly people, outdoor workers and communities with fragile health systems—worsening global health inequities.

In this context, the Belem Health Action Plan, endorsed by more than 80 countries and organisations, seeks to build climate-resilient, equitable and adaptive health systems. The BHAP outlines five key focus areas:

(1) strengthening surveillance and early-warning systems for heatwaves, floods, extreme weather and infectious diseases;

(2) accelerating research and innovation in climate-sensitive health risks and technologies;

(3) promoting health equity and justice by protecting vulnerable communities;

(4) building capacity in healthcare workforces for climate-related emergencies; and

(5) aligning health, climate, and development policies for coherent action.

A core emphasis of the plan is “shifting funding and power to frontline communities,” ensuring that adaptation resources directly reach the most affected.

The $300 million philanthropic commitment complements the BHAP by supporting integrated climate-health solutions. This inaugural funding tranche will prioritize extreme heat mitigation, expansion of early-warning systems, reduction of air pollution, and improved management of climate-sensitive diseases such as malaria, dengue and cholera. A major component involves integrating climate and health data platforms, enabling real-time forecasting and targeted responses. The initiative also stresses the urgency of action, with the past decade recorded as the hottest in human history, and projections indicating continued extreme temperatures.

However, COP30 also highlighted a persistent adaptation finance gap, especially for health-focused interventions. The UN Adaptation Gap Report (2025) estimates that developing countries will require $310–365 billion annually by 2035 to meet adaptation needs, while current global flows average just $40 billion per year. Health-related adaptation receives an even smaller share. India’s 2023 National Communication to the UNFCCC projects a need for $643 billion by 2030 for adaptation, though the country has significantly scaled up domestic spending to $146 billion (5.6% of GDP) in 2021–22.

The Belem outcome reflects a paradigm shift—viewing climate adaptation not merely as environmental protection but as safeguarding human lives, livelihoods and health systems. By institutionalising a climate-health framework, strengthening collaborations between governments, global agencies and philanthropies, and expanding financing avenues, COP30 has laid the foundation for a more people-centred climate agenda. The challenge now lies in rapidly operationalising BHAP’s strategies at national and local levels, ensuring robust funding, and building resilient health systems capable of withstanding an increasingly volatile climate future.

AI-Powered Early Warning System for Elephant Conservation

  • 21 Aug 2025

Introduction

Human-elephant conflict is a persistent challenge in India, particularly in regions where railway lines intersect traditional migratory routes of elephants. In response, the Tamil Nadu Forest Department, in collaboration with the railways, has pioneered an AI-enabled early warning system in the Walayar–Madukkarai forest range along the Kerala–Tamil Nadu border. This initiative, operational since February 2024, has emerged as a model for technology-driven wildlife conservation.

Background

The Western Ghats, a UNESCO World Heritage Site and a critical biodiversity hotspot, serves as a migratory corridor for elephants moving between the Nilgiris, Sathyamangalam, and Kerala forests. However, expanding rail and road infrastructure, coupled with land-use changes and increasing human presence, has fragmented these habitats.

The Coimbatore Forest Division alone reported nearly 9,000 elephant straying incidents between 2021 and 2023. The Madukkarai range, traversed by two railway tracks through reserved forests, has been particularly vulnerable. Since 2008, 11 elephants, including calves, have died due to train collisions in this area, underscoring the urgency for preventive measures.

The AI-Powered Surveillance System

  • Infrastructure: The system comprises 12 surveillance towers fitted with 24 high-resolution thermal cameras, strategically placed along a vulnerable 7-km stretch of railway track.
  • Technology: Using artificial intelligence and machine learning, the cameras detect elephant presence up to 100 feet near tracks. The system is modeled on surveillance technology used by the Indian Army at border areas.
  • Command Centre: Located near Walayar, it is staffed by trained forest personnel and local tribal youth. The system operates 24×7, sending real-time alerts to railway control rooms, loco pilots, and patrol teams.
  • Integration with Railways: Alerts prompt loco pilots to slow down or halt trains, while forest staff guide elephants safely across or divert them through designated underpasses.
  • Results: Since its commissioning, the system has facilitated over 6,500 safe elephant crossings and generated over 5,000 alerts, with zero elephant fatalities reported.

Broader Significance

  1. Wildlife Safety: The system ensures unhindered migratory movement of elephants, mitigating human-wildlife conflict.
  2. Community Involvement: Employment of tribal youth in monitoring enhances local participation in conservation.
  3. Judicial Oversight: The initiative aligns with the Madras High Court’s 2021 directive to minimize elephant deaths on railway tracks.
  4. Multi-Species Benefit: The cameras also detect human presence, reducing risks of accidents and aiding in conflict management.

Challenges and Way Forward

Elephants are highly adaptive and often circumvent traditional barriers such as trenches or solar fences, making AI-driven monitoring more reliable. However, scaling up faces challenges of financial allocation, technical expertise, and maintenance. The Tamil Nadu government has announced plans to expand the system to four more vulnerable areas including Dharmapuri and Hosur, indicating policy commitment.

To ensure long-term success:

  • Similar AI-based systems should be introduced across critical elephant corridors in states like Assam, Odisha, and Karnataka.
  • Railway infrastructure should integrate wildlife underpasses and overpasses with AI monitoring.
  • A national-level database linking forest departments and railways could enhance coordination.
  • Awareness campaigns and community engagement must complement technological solutions.

Conclusion

The AI-powered early warning system in Coimbatore division demonstrates how advanced technology, when integrated with local knowledge and institutional support, can resolve persistent conservation challenges. With elephants being a keystone species vital to ecosystem stability, such interventions are crucial to balance developmental imperatives with biodiversity conservation. Replicating and scaling up this initiative across India could significantly reduce human-elephant conflict and serve as a global model for AI-driven wildlife protection.

Marine Litter Crisis: A Call for Unified Global and National Action

  • 11 Apr 2025

Context:

Marine litter, particularly plastic waste, has emerged as a critical global environmental issue. With over 700 marine species affected and microplastics infiltrating food chains, the issue demands both global cooperation and local implementation. Despite India's efforts in solid and plastic waste management, a direct legislative mandate to mitigate marine litter remains absent.

Magnitude of the Crisis

  • UNESCO warns: By 2050, plastic volume in oceans could exceed fish biomass.
  • Ghost Gear: Lost/discarded fishing gear (nets, traps, lines) poses severe threats:
    • 5.7% of nets, 8.6% of traps, and 29% of fishing lines are lost annually (UNEP).

Key Global Frameworks

  • MARPOL (Annex V) – In force since 1983, regulates ship-generated garbage disposal in oceans.
  • UNCLOS (1994) – Part XII mandates nations to prevent pollution from land-based and sea-based sources, including ghost gear.
  • Global Programme of Action (1995) – First UN initiative addressing land-based marine pollution.
  • SDGs:
    • SDG 14.1: Reduce marine pollution, especially plastics.
    • SDG 6.3: Improve water quality via integrated management.
  • Honolulu Commitment (2011):
    • Reduce land-based debris
    • Address sea-based litter
    • Clean up accumulated coastal & deep-sea litter

Institutional and Voluntary Actions

  • Global Partnership on Marine Litter (GPML, 2012) – UNEP-led initiative uniting stakeholders for source-to-sea plastic mitigation.
  • AHEG (2017) – UNEP expert group assessing policy responses for marine litter and recommending frameworks.
  • Clean Seas Campaign (2017) – Advocates for elimination of single-use plastics and behaviour change.
  • UNEA Resolutions on Marine Litter:
    • Adopted in 2014 (UNEA-1), 2016 (UNEA-2), 2017 (UNEA-3), and 2019 (UNEA-4).
    • While non-binding, they push for total elimination of litter discharge and evidence-based policymaking.

Scientific Support

  • GESAMP (Group of Experts on the Scientific Aspects of Marine Environmental Protection) has, since 2010, guided scientific research on:
    • Microplastic sources
    • Marine ecosystem impacts
    • Monitoring and mitigation strategies

India’s Current Status and Initiatives

  • No direct marine litter law or policy yet exists.
  • A multi-ministerial body involving MoES, MoST, and MoFAD is drafting a National Marine Litter Action Plan.
  • Relevant policies in place:
    • Plastic Waste Management Rules, 2016 (includes Extended Producer Responsibility – EPR)
    • Solid Waste Management Rules, 2016
    • Water (Prevention and Control of Pollution) Act, 1974

Challenges in India

  • Fragmented implementation
  • Limited monitoring of litter entering marine zones
  • Lack of focus on coastal-level execution

Way Forward

  • Adopt a national marine litter policy with local implementation mechanisms.
  • Strengthen enforcement of international agreements like MARPOL and UNCLOS.
  • Promote circular economy models and enhance waste infrastructure.
  • Encourage public-private partnerships, community awareness, and behaviour change.
  • Support scientific monitoring, research, and innovation.

Conclusion

The transboundary nature of marine litter necessitates global cooperation backed by national accountability. India's next steps must include a dedicated marine litter law, enhanced inter-ministerial coordination, and alignment with international best practices to secure its coastal and marine ecosystems.

Child Sexual Abuse in India

  • 31 May 2025

Context:

A landmark global study published in The Lancet has brought to light the disturbing scale of child sexual abuse (CSA) worldwide. Using data from 204 countries (1990–2023), the study by the Institute for Health Metrics and Evaluation found that 18.9% of women and 14.8% of men globally were victims of CSA. In India, 30.8% of women and 13.5% of men reported having experienced sexual violence before turning 18, placing it among the countries with the highest prevalence for women.

The research revealed that most abuse begins in childhood, with 67% of girls and 72% of boys facing their first abuse before 18. A staggering 26.9% of Indian women and 9.4% of men aged 20–24 continue to report having been abused during their childhood, indicating the persistence of this crisis.

Context and Contributing Factors

CSA in India is exacerbated by societal stigma, patriarchal norms, and underreporting, particularly among boys. Male survivors face additional silence due to entrenched ideas of masculinity and victim-blaming. Abuse often occurs in familiar settings, including homes and schools, with digital exploitation emerging as a growing threat.

Furthermore, regional disparities persist. Urban areas report more digital abuse, while rural areas suffer from familial exploitation compounded by lack of awareness and legal access. States like Kerala and Maharashtra show better reporting, while Bihar and Uttar Pradesh lag.

Legal and Institutional Response

India enacted the Protection of Children from Sexual Offences (POCSO) Act in 2012, a gender-neutral law covering a wide range of sexual offences with child-friendly procedures. However, implementation gaps remain:

  • Conviction rates below 30%
  • Backlogged trials
  • Insufficient training for police and judiciary

Additionally, mental health services for survivors are scarce, and sex education in schools remains inadequate, leaving children vulnerable and uninformed.

Civil Society and Global Comparisons

NGOs such as Save the Children, Kailash Satyarthi Children’s Foundation, and HAQ have played key roles in rehabilitation and awareness. International best practices offer valuable lessons:

  • Nordic countries integrate mandatory sex education.
  • Australia uses public awareness and national offender registries.

Recommendations and Way Forward

A multisectoral, prevention-focused approach is vital:

  • Legal Reforms
    • Fast-track POCSO courts
    • Child-friendly police units
    • Sensitisation training for frontline staff
  • Education System Overhaul
    • Include modules on “safe/unsafe touch” and digital safety
    • Train teachers to detect and report CSA
  • Community Engagement
    • Empower Panchayats and child welfare committees
    • Conduct grassroots campaigns to break the culture of silence
  • Technological Safeguards
    • Strengthen helplines like Childline 1098
    • Collaborate with tech platforms for safer digital ecosystems
  • Research and Data Collection
    • Create a national CSA data repository
    • Promote evidence-based policymaking through academic and NGO partnerships

Conclusion

The Lancet study underscores that CSA is not merely a criminal issue—it is a public health and social emergency. Laws like POCSO, while crucial, are not enough. What is needed is a coordinated, empathetic, and data-driven strategy that spans homes, schools, communities, and cyberspace. Only then can India safeguard its children not just from predators, but from institutional neglect and societal apathy.

Plastic Pollution in the Indian Himalayas

  • 13 May 2025

In News:

The fragile ecosystems of the Indian Himalayas are increasingly threatened by mounting plastic pollution. According to the Himalayan Cleanup (THC) 2024 report, over 70% of the plastic waste collected in this region is non-recyclable, posing a severe environmental and ecological challenge. This pollution not only endangers biodiversity but also impacts the livelihoods and health of mountain communities reliant on pristine natural resources.

Nature and Sources of Plastic Pollution

The report highlights that more than 80% of plastic debris in the Himalayas stems from single-use food and beverage packaging. These include instant noodles, energy drinks, and snack wrappers, with prominent brands such as Wai Wai, Maggi, Sting, Mountain Dew, Lays, and Bingo contributing substantially to the waste load. A striking 71% of this plastic waste comprises multi-layered plastics (MLPs), which are notoriously difficult to recycle due to their composite nature and lack of viable recycling markets.

Multi-layered plastics form nearly 68.5% of the total waste, rendering traditional recycling methods ineffective. These plastics often end up as litter in remote mountain areas, where waste collection and management infrastructure is minimal or absent, exacerbating environmental degradation.

Environmental and Socioeconomic Implications

Plastic pollution in the Himalayas disrupts fragile mountain ecosystems, threatening native flora and fauna. The persistence of non-biodegradable waste affects soil quality, water sources, and the aesthetic and cultural value of the region. Moreover, plastic litter contributes to microplastic contamination in water bodies, entering food chains and posing health risks to local populations and wildlife alike.

Economically, the growing plastic menace undermines tourism, a vital livelihood source in many Himalayan districts. Untouched landscapes attract visitors, but increasing waste reduces their appeal, impacting local economies dependent on sustainable tourism.

Policy Recommendations from the THC 2024 Report

To address this mounting crisis, the report recommends comprehensive policy and administrative measures:

  • Ban on Multi-Layered Plastics (MLPs): Given that MLPs constitute nearly 68.5% of plastic waste and are largely non-recyclable, the report calls for an immediate ban on their manufacture, sale, and distribution, especially in sensitive ecological zones such as the Himalayas.
  • Extended Producer Responsibility (EPR): The report urges policymakers to enforce stringent EPR frameworks, holding manufacturers and brands accountable for the lifecycle of their packaging waste. This would incentivize producers to innovate sustainable packaging solutions and participate actively in waste collection and recycling.
  • Restrict Junk Food and Energy Drinks near Schools: Recognizing the health and environmental impact, the report recommends banning the sale of such products near educational institutions to curb littering and reduce children’s exposure to unhealthy food items.
  • Mandatory Front-of-Pack Labelling: To inform consumers about the environmental and health risks, the report advocates mandatory clear labelling on high-risk products, promoting responsible consumption.
  • Transition from Recycling to Waste-Redesign: The focus should shift from merely recycling waste to redesigning packaging to eliminate waste generation at source. Adopting a ‘design-out-waste’ approach can significantly reduce plastic pollution.
  • Empowering Local Governance: The report emphasizes strengthening rural and mountain municipalities by providing technical resources, funding, and training in waste management to enhance local capacity to handle plastic waste effectively.

Conclusion

The Himalayan plastic pollution crisis underscores the urgent need for coordinated action involving governments, industries, and local communities. Effective implementation of bans on non-recyclable plastics, coupled with robust producer responsibility laws and community-based waste management, can restore the ecological balance of the Himalayas. Additionally, fostering public awareness and promoting sustainable consumption patterns remain crucial in preserving this ecologically sensitive and culturally significant region for future generations.

India’s Human Development Index 2025

  • 08 May 2025

In News:

India has made steady progress in the Human Development Index (HDI), improving its rank from 133rd in 2022 to 130th in 2023 among 193 countries. Its HDI value rose from 0.676 to 0.685, reflecting advancements in key areas such as health, education, and income. Despite these gains, significant challenges, particularly inequality, continue to limit India’s overall human development.

Understanding India’s HDI Progress

The HDI is a composite measure that captures a country’s average achievements in three core dimensions: health (life expectancy), education (years of schooling), and income (gross national income per capita). India currently belongs to the ‘medium human development’ category and is approaching the threshold for ‘high human development’ (an HDI value of 0.700).

Several factors have driven India’s recent improvement:

  • Health: Life expectancy increased markedly from 58.6 years in 1990 to 72 years in 2023. This improvement is supported by flagship health schemes like Ayushman Bharat, the National Rural Health Mission, Janani Suraksha Yojana, and PoshanAbhiyaan, which have enhanced healthcare access and nutrition.
  • Education: The expected years of schooling grew from 8.2 years in 1990 to 13 years in 2023, while mean years of schooling rose from 4.1 to 6.9 years. Policies such as the Right to Education Act and the National Education Policy 2020 have played critical roles in improving educational quality and accessibility.
  • Income: India’s per capita Gross National Income surged from $2,167 in 1990 to $9,046 in 2023. Social welfare programs like MGNREGA and Jan Dhan Yojana have contributed to this growth by lifting approximately 135 million people out of multidimensional poverty between 2015-16 and 2019-21.

Persistent Challenges: Inequality and Gender Disparity

Inequality poses a major impediment to India’s HDI progress. It is estimated that disparities reduce India’s HDI by 30.7%, one of the highest losses in South Asia. The wealthiest 10% earn nearly 57% of the national income, while the poorest 50% share only 13%. Gender inequality further complicates the picture: India’s Gender Development Index (GDI) stands at 0.874, with female HDI (0.631) significantly lower than male HDI (0.722). Despite policy efforts, female labor force participation and political representation remain limited.

Regional and Global Context

Regionally, India lags behind neighbors like China (75th) and Sri Lanka (89th) but shares a similar HDI value with Bangladesh (130th), and surpasses Nepal (145th) and Pakistan (168th). Globally, the 2025 Human Development Report highlights a slowdown in HDI growth—the slowest since 1990—but emphasizes the transformative role of Artificial Intelligence (AI) in fostering inclusive development. India holds 20% of global AI researchers, positioning it to harness AI’s potential in sectors such as healthcare, education, and productivity.

Strategic Innovations and National Initiatives

India’s pursuit of sustainable development complements its HDI goals through key initiatives:

  • Scientists have developed a metal-free catalyst leveraging mechanical energy for sustainable hydrogen fuel production, supporting the National Green Hydrogen Mission to promote clean energy.
  • The Indian Navy’s deployment of INS Sharda to the Maldives for its inaugural Humanitarian Assistance and Disaster Relief (HADR) exercise under the MAHASAGAR vision showcases India’s leadership in regional disaster preparedness and maritime security.
  • Developments in regional defense, such as Iran’s unveiling of the solid-fuel GhassemBasir medium-range missile, highlight ongoing security challenges necessitating vigilance and capability enhancement.

Way Forward

To advance into the ‘high human development’ category, India must:

  • Implement targeted policies to reduce income and gender inequalities.
  • Invest in quality education and healthcare, especially for underserved populations.
  • Promote inclusive economic growth benefiting marginalized groups.
  • Leverage emerging technologies like AI responsibly to enhance public services without deepening disparities.
  • Strengthen regional cooperation and disaster resilience to protect socio-economic gains.

Conclusion

India’s HDI improvement reflects meaningful progress in health, education, and income. Yet, to fully realize its human development potential, India must tackle persistent inequalities and strategically harness technological innovations alongside regional cooperation. With sustained, inclusive efforts, India can continue its upward trajectory toward equitable growth and global leadership.

Biodiversity Benefit Sharing Regulations 2025

  • 07 May 2025

In News:

The National Biodiversity Authority (NBA), under the Biological Diversity Act, 2002, has notified the Biodiversity Benefit Sharing Regulations, 2025 to regulate fair and equitable sharing of benefits arising from the use of India’s rich biological resources, including digital sequence information (DSI). This move strengthens India’s compliance with global Access and Benefit Sharing (ABS) frameworks under the Convention on Biological Diversity (CBD).

Background and Need

India’s vast biodiversity is a vital national asset, deeply linked with traditional knowledge of local and indigenous communities. The updated regulations address concerns that industries and researchers benefit commercially from biological resources without adequately compensating custodians of biodiversity or associated knowledge. The 2025 regulations supersede the 2014 guidelines and incorporate digital sequence information, a significant addition in the biotechnology era, where genetic information is often used without accessing physical resources.

Key Provisions of the Regulations

  • Turnover-Based Benefit Sharing Slabs:The regulations introduce slabs based on the annual turnover of users accessing biological resources or associated knowledge:
    • ?0–5 crore: No benefit sharing
    • ?5–50 crore: 0.2% of ex-factory turnover
    • ?50–250 crore: 0.4%
    • Above ?250 crore: 0.6%
  • Mandatory Reporting:All users with annual turnover exceeding ?1 crore must submit an annual statement detailing biodiversity resource usage.
  • Exemption for Cultivated Medicinal Plants:In alignment with the Biological Diversity (Amendment) Act, 2023, cultivators of medicinal plants, and Indian traditional medicine practitioners are exempt from benefit sharing. This supports promotion of medicinal plant cultivation while balancing conservation.
  • High-Value and Threatened Species Clause:For species with significant conservation or economic importance — such as red sanders, sandalwood, agarwood, and other notified threatened species — minimum benefit sharing is set at 5%, which can rise above 20% for commercial exploitation.
  • Inclusion of Digital Sequence Information (DSI):Recognizing that genetic data can substitute physical biological samples, DSI has been brought under the ABS ambit, ensuring benefits from its use are also equitably shared.
  • Researchers and Intellectual Property Rights (IPR):Those conducting research or applying for IPR based on Indian biodiversity must comply with benefit-sharing obligations.

Mechanism for Utilization of Benefits

The collected benefits are distributed such that approximately 10–15% is retained by the NBA to support biodiversity conservation efforts, while the remaining is transferred to claimant communities and biodiversity conservers who have preserved and nurtured these resources.

Institutional Role: National Biodiversity Authority (NBA)

Established in 2003 and headquartered in Chennai, the NBA implements the Biological Diversity Act. Its key functions include regulating access to biological resources, granting approvals to foreign and domestic entities, overseeing State Biodiversity Boards (SBBs), and advising the central government on biodiversity conservation policies. The NBA ensures compliance with international protocols like the Nagoya Protocol under the CBD, reinforcing India’s commitment to global biodiversity governance.

Global Context and International Compliance

At COP16 of the CBD held in Cali, Colombia (2024), member nations adopted a multilateral mechanism to ensure benefit sharing from the use of DSI. This is critical given the global usage of genetic resources by sectors such as pharmaceuticals, agriculture, cosmetics, and biotechnology. India’s updated regulations align with these international norms, demanding equitable compensation for communities that are custodians of biodiversity and traditional knowledge.

Conclusion

The Biodiversity Benefit Sharing Regulations 2025 mark a significant advancement in India’s biodiversity governance by closing regulatory gaps, especially around digital information and high-value species. The policy balances biodiversity conservation with sustainable use and incentivizes communities by ensuring fair economic returns, thereby promoting India’s leadership in global biodiversity stewardship.

Glacier Melting and Climate Change

  • 25 Feb 2025

Context:
The world’s glaciers are melting at an alarming rate due to anthropogenic climate change, making them one of the leading contributors to global sea-level rise. Recent studies have revealed that more than 7 trillion tonnes of ice have been lost since 2000, with 2023 marking the worst year on record.

Key Data and Trends

  • Between 2000 and 2023, glaciers lost 6.54–7 trillion tonnes of ice, contributing approximately 18 mm to global sea levels.
  • The rate of glacier melt increased by 36% over the past decade:
    • 2000–2011: 255 billion tonnes lost annually
    • 2011–2023: 346 billion tonnes annually
    • 2023 alone: 604 billion tonnes lost — the highest annual loss recorded
  • Globally, glaciers have lost 5% of their ice, with regional losses ranging from 2% to 39%.
  • Alaska is the fastest-melting region, losing 67 billion tonnes per year (22% of global glacier mass loss).
  • The Canadian Arctic (20%), Greenland periphery (13%), and Southern Andes (10%) are also major contributors.
  • Central European glaciers are shrinking the fastest in relative terms, having lost 39% of their volume since 2000.

Causes of Glacier Meltdown

  • Rising global temperatures due to greenhouse gas emissions from fossil fuel combustion.
  • Extreme heatwaves and record summer temperatures, especially in vulnerable regions like the Alps and Andes.
  • Reduced snowfall, leading to insufficient accumulation to balance seasonal melting.
  • Human-induced climate change, confirmed as the primary driver of accelerated glacier loss.

Impacts of Glacier Melting

  • Sea Level Rise
    • Glacier melt contributes more to sea-level rise than ice loss from Greenland and Antarctica.
    • Currently accounts for 0.75 mm/year of sea-level rise; projected to increase further.
  • Water Resources & Scarcity: Melting glaciers provide short-term water surpluses but pose a long-term threat of freshwater scarcity, especially for regions dependent on glacier-fed rivers (e.g., Central Asia, Central Andes).
  • Geohazards & Natural Disasters: Glacier retreat increases the risk of glacial lake outburst floods (GLOFs), landslides, and downstream flooding.
  • Biodiversity Loss: Shrinking glaciers affect freshwater ecosystems and species reliant on glacial water.
  • Economic Disruptions: Sectors like agriculture and tourism are adversely impacted due to changes in water availability and scenic landscape loss.

Scientific Insights and Global Assessments

  • The Glacier Mass Balance Intercomparison Exercise (GlaMBIE) led by international experts used unified satellite and field data to provide the most accurate glacier loss estimates to date.
  • Glaciers are now recognized as apolitical indicators of climate change, painting an unbiased picture of global warming trends.
  • The IPCC stresses that without rapid cuts in emissions, glacier melt will continue or accelerate throughout the century, worsening its contribution to sea-level rise and regional climate vulnerabilities.
  • Glaciers contribute 20% to observed global sea-level rise (2003–2016), behind only thermal expansion (33%), and more than the Greenland Ice Sheet (17%).

Conclusion

Glaciers are not just scenic features; they are critical to Earth’s hydrological and climatic systems. Their rapid melting signals an urgent planetary emergency that demands intensified climate action, focused on mitigation, adaptation, and international cooperation. For India, where Himalayan glaciers are vital for river systems and agriculture, this global trend holds serious implications for water security, disaster risk management, and sustainable development.

Surge in E-Waste Generation in India

  • 29 Dec 2024

In News:

India has seen a significant increase in electronic waste (e-waste) generation, rising by 72.54% from 1.01 million metric tonnes (MT) in 2019-20 to 1.751 million MT in 2023-24. The sharpest rise occurred between 2019-20 and 2020-21, driven by increased electronic consumption due to the COVID-19 pandemic's work-from-home and remote learning arrangements.

Stubble burning continues to be a significant environmental challenge, but the development and adoption of technologies for utilizing paddy straw can offer viable solutions. Both large- and small-scale technologies can convert rice straw into valuable products like biofuels, power, and fertilizers. To ensure widespread implementation, efforts must be made to increase awareness among farmers and stakeholders, coupled with strong policy support and infrastructural investment. A collaborative approach involving the government, industries, and farmers is essential for sustainable management of rice straw, benefiting both the environment and the economy.

Andhra Pradesh's Natural Farming Model

  • 18 Nov 2024

In News:

Andhra Pradesh's (AP) natural farming model presents a transformative opportunity to reshape the state’s agricultural landscape by 2050. An analysis by the Food and Agriculture Organization (FAO), in collaboration with the AP government, reveals how scaling natural farming could employ more farmers, increase incomes, and foster sustainable agricultural practices, potentially surpassing the benefits of conventional industrial agriculture.

AgroEco2050: Exploring Two Agricultural Futures

The AgroEco2050 initiative aimed to envision two possible futures for Andhra Pradesh’s agricultural systems by 2050:

  • Industrial Agriculture Path: Focusing on intensification of conventional farming, relying heavily on chemicals, machinery, and monocultures.
  • Natural Farming Path: Expanding agroecological practices, relying on regenerative, chemical-free farming methods to create more jobs, better livelihoods, and improve the environment.

The study compared these pathways, analyzing their impacts on employment, income, food production, biodiversity, and land use.

Key Findings: Natural Farming’s Impact on Employment and Income

  • Employment Growth
    • By 2050, natural farming would employ twice as many farmers as industrial agriculture: 10 million compared to 5 million.
    • Unemployment in natural farming would decrease to 7%, in stark contrast to a projected 30% unemployment rate in the industrial agriculture scenario.
  • Farmer Income
    • Natural farming is expected to be more profitable for farmers due to lower input costs (seeds, fertilizers, machinery) and higher market prices for high-quality produce.
    • The income gap between farmers and non-farmers, which stood at 62% in 2019, would decrease to 22% under natural farming by 2050, a sharp improvement compared to the 47% gap predicted under industrial agriculture.

What is Natural Farming?

Natural farming is an ecological, chemical-free farming system that emphasizes the use of locally available resources. Key practices include:

  • Biodiversity-based pest management
  • On-farm biomass recycling (e.g., mulching)
  • Indigenous techniques like using cow dung and urine for soil fertility.

Globally recognized as a form of regenerative agriculture, it offers a sustainable alternative to industrial agriculture by sequestering carbon and restoring soil health.

Global Adoption

States like Andhra Pradesh, Karnataka, Himachal Pradesh, and others are already adopting natural farming. While still evolving, its acceptance among farmers is steadily growing.

Zero Budget Natural Farming (ZBNF) in Andhra Pradesh

Origin and Growth

  • In 2016, Andhra Pradesh launched the Zero Budget Natural Farming (ZBNF) initiative to offer a sustainable alternative to capital-intensive agriculture.
  • This program, implemented by RythuSadhikaraSamstha, targets covering 6 million farmers across 6 million hectares.

National Recognition

The ZBNF approach gained national attention when it was featured in the 2019 Union Budget, aimed at doubling farmers' incomes by 2022. The central government now promotes this model under the Paramparagat Krishi Vikas Yojana (PKVY).

Challenges in Scaling Natural Farming

  • Farmer Training and Support
    • Farmers need ongoing education and support to transition effectively to natural farming. Current training systems often fail to address the full scope of their needs.
  • Certification Barriers
    • The certification process for organic farming, including Participatory Guarantee Systems (PGS) and third-party certifications, is complex and costly, presenting a barrier for small-scale farmers.
  • Marketing and Procurement Challenges
    • There is a lack of effective marketing systems for organic products, which hampers the ability of farmers to sell their produce at fair prices.
    • Without strong procurement or buy-back systems, farmers may struggle to find markets for their products.
  • Policy and Funding Gaps
    • Organic and natural farming programs still receive minimal funding compared to subsidies for chemical fertilizers, impeding large-scale adoption.
    • Slow state-level implementation and a continued reliance on chemical inputs also delay the widespread shift to natural farming.

Moving Forward

  • Scientific Research on Yields
    • To address concerns about lower yields for staple crops, more scientific research is needed to assess the long-term viability of natural farming, especially for crops like wheat and rice, which are crucial for India’s food security.
  • Localized Adoption
    • Natural farming may be best suited for non-staple crops or localized farming, balancing sustainability with the need for food security.
  • Risk Mitigation for Food Security
    • Careful evaluation of natural farming’s impact on staple crop yields is necessary to avoid the food security risks witnessed in countries like Sri Lanka, where a sudden shift to organic farming led to reduced yields and increased prices.

Conclusion

The Andhra Pradesh natural farming model offers a promising alternative to industrial agriculture, with the potential to create jobs, improve farmers' incomes, and promote environmental sustainability. However, for this vision to become a reality, significant efforts must be made to address challenges related to training, certification, marketing, and funding. With continued research, policy support, and community involvement, natural farming can play a crucial role in feeding the future and promoting a more sustainable agricultural system.

Climate Change and Methane Emissions in the Amazon Rainforest

  • 16 Oct 2024

Overview

Recent research from the University of São Paulo reveals that climate change is poised to significantly disrupt the methane cycle in the Amazon rainforest, with potential global repercussions. Rising temperatures and increased flooding are impacting microbial activity in both floodplain and upland forest soils, leading to contrasting changes in methane dynamics.

Key Findings

  • Methane Uptake Reduction: The study indicates that methane absorption in upland forest soils could decrease by as much as 70% in warmer, drier conditions. This reduction diminishes the forest's role as a methane sink.
  • Floodplain Contributions: Floodplains, which cover over 800,000 square kilometers during the rainy season, contribute up to 29% of global wetland methane emissions. Here, methane-producing microbes thrive due to the breakdown of organic matter.

Understanding the Methane Cycle

  • Definition: The methane cycle encompasses the processes that control the production, consumption, and release of methane (CH4) in the environment.
  • Microbial Roles:
    • Methanogens produce methane, primarily in waterlogged conditions.
    • Methanotrophs consume methane, living in drier, oxygen-rich soils. These interactions are critical in regulating methane levels in the atmosphere.
  • Sources and Sinks: While wetlands and other environments release methane, hydroxyl radicals (OH) in the troposphere act as a natural sink, helping to oxidize methane into carbon dioxide.

Climate Change Impacts on the Methane Cycle

  • Imbalance of Sources and Sinks: As global temperatures rise, the release of methane from soils may increase, exacerbating climate change effects.
  • Melting Clathrates: Methane clathrates, trapped in cold sediments, are at risk as warming causes them to release methane, further contributing to greenhouse gas concentrations.

Global Consequences of Methane Disruption

  • Climate Change Amplifier: Methane is the second most significant greenhouse gas, with a global warming potential 28 times greater than carbon dioxide over a century.
  • Air Quality and Health: Increased methane emissions can lead to higher levels of tropospheric ozone, resulting in respiratory health issues and reduced air quality.
  • Biodiversity Threats: The changes in methane dynamics can destabilize ecosystems, leading to shifts in species distributions and loss of biodiversity.

Balancing the Methane Cycle

To mitigate the impacts of methane emissions, various strategies can be employed:

  1. Enhanced Landfill Design: Utilizing gas collection systems to capture methane for energy rather than allowing it to escape.
  2. Livestock Management: Introducing feed additives to reduce methane emissions from ruminants.
  3. Sustainable Agricultural Practices: Implementing techniques like alternative wetting and drying in rice cultivation to lower methane output.
  4. Soil Health Improvements: Promoting organic fertilization and crop rotation to foster aerobic conditions in soils.

Research Insights

The study involved subjecting soil samples from floodplains and upland forests to elevated temperatures and varying humidity levels. Results indicated:

  • Stable methane emissions in floodplains alongside an increase in methane-producing microbes.
  • A significant decline in methane uptake in upland soils due to temperature sensitivity, with higher temperatures reducing microbial diversity.

Conclusion

The Amazon rainforest plays a crucial role in regulating global methane levels, and its response to climate change is vital for understanding future greenhouse gas emissions. As these ecosystems face increased pressure from rising temperatures and changing hydrological conditions, it becomes imperative to enhance our understanding and management of methane dynamics to mitigate broader climate impacts.
