Why in News

The Pacific island nation of Tuvalu is facing an existential threat due to rising sea levels caused by climate change. Large parts of the country risk submergence by the end of the 21st century, prompting efforts to secure livelihoods, preserve sovereignty, and plan for possible displacement.

About Tuvalu

Tuvalu, formerly known as the Ellice Islands, is a small Polynesian island country located in the west-central Pacific Ocean. It lies roughly midway between Australia and Hawaii, with Kiribati to its north and Fiji to its south.

With a total land area of just 26 sq. km, Tuvalu is the fourth smallest country in the world. It consists of nine islands, including four reef islands and five coral atolls. The capital, Funafuti, is the most populous atoll and serves as the administrative and economic centre.

A defining feature of Tuvalu is its extremely low elevation—no point is higher than 4.5 metres above sea level. Additionally, the country has no rivers, and its climate is tropical, hot, and rainy.

Political System

Tuvalu gained independence from the United Kingdom in 1978. It functions as a parliamentary democracy under a constitutional monarchy and is part of the Commonwealth Realm.

Charles III is recognized as the head of state and is represented by a Governor-General.

The political system is unique due to the absence of formal political parties. The Prime Minister is elected by members of the legislature.

Economy

Tuvalu’s economy is fragile and aid-dependent:

• Majority of people engage in subsistence farming and fishing
• Heavy reliance on remittances from overseas workers
• Limited exports such as copra
• Revenue from fishing licenses and stamp sales
• Significant dependence on foreign aid and imports

Due to limited natural resources and geographic isolation, economic diversification remains a challenge.

Climate Change Threat

Tuvalu is considered one of the most vulnerable countries to climate change and sea-level rise:

• Submergence Risk: Rising sea levels threaten to inundate large parts of the islands
• Saltwater Intrusion: Contamination of groundwater affects drinking water and agriculture
• Coastal Erosion: Loss of land and infrastructure
• Extreme Weather Events: Increased frequency of cyclones and flooding

The country’s very existence is under threat, raising serious concerns about climate refugees

and loss of national sovereignty.

Global Significance

Tuvalu represents a symbol of climate injustice:

• Contributes negligibly to global emissions but suffers disproportionately
• Raises legal and ethical questions about statehood if territory disappears
• Has advocated strongly in global forums like the United Nations for urgent climate action

It has also explored innovative solutions such as creating a “digital nation” to preserve its identity and governance even if physical land is lost.

Way Forward

• Global Climate Action: Reduction in greenhouse gas emissions under international agreements
• Climate Financing: Support from developed nations for adaptation and resilience
• Planned Relocation Policies: Migration with dignity and legal safeguards
• Technological Solutions: Coastal protection, land reclamation, and digital governance

Conclusion

Tuvalu’s crisis is a stark reminder of the real and immediate impacts of climate change. It highlights the urgent need for collective global responsibility, equitable climate policies, and sustainable development to protect vulnerable nations and communities.

Tribal Ecological Communitarianism (TEC) is emerging as an alternative model of sustainable development that challenges mainstream economic systems driven by excessive capital accumulation and profit maximisation. Rooted in indigenous traditions, TEC combines collective ownership, ecological stewardship, cooperative labour, and equitable resource distribution with a strong cultural relationship with nature.

The model highlights how tribal communities have historically maintained ecological balance while ensuring social security and sustainable livelihoods.

What is Tribal Ecological Communitarianism?

TEC is a socio-economic framework where communities collectively manage natural resources and organise economic activities in harmony with ecological systems.

Unlike market-centric models focused on individual ownership and extraction, TEC emphasises:

• Collective welfare
• Ecological responsibility
• Intergenerational sustainability
• Community-based  decision-making

Features of Tribal Ecological Communitarianism

Collective Ownership

Land, forests, water bodies, and natural resources are held collectively by the community rather than by private individuals.

Ecological Stewardship

Humans are viewed as custodians of nature with a moral responsibility to preserve ecosystems for future generations.

Cooperative Labour

Agriculture, irrigation, construction, and forest management are often carried out through communal cooperation instead of wage-based labour systems.

Sacred Relationship with Nature

Many tribal traditions protect forests, rivers, mountains, and wildlife through cultural taboos and sacred practices.

Equitable Distribution

Food, wealth, and community resources are distributed relatively equally to ensure collective social security and survival.

Significance of TEC

Resource Sovereignty

Community control over natural resources ensures sustainable management of forests, land, and water systems according to local needs.

Climate Mitigation

Traditional tribal conservation practices help protect forests and peatlands, which function as important carbon sinks and Natural Climate Solutions.

Preservation of Indigenous Knowledge

Tribal communities possess valuable ethno-ecological knowledge regarding medicinal plants, biodiversity, drought-resistant crops, and sustainable farming practices.

Eco-Pedagogy

Environmental literacy is transmitted through oral traditions, rituals, and lived cultural practices, promoting ecological consciousness from childhood.

Biomimetic Development

Traditional tribal housing and irrigation systems often imitate natural ecological patterns, reducing habitat fragmentation and environmental degradation.

Challenges Associated with TEC

Scalability Issues

Communal systems based on trust and close social ties become difficult to sustain in large urbanised societies.

Limited Access to Credit

Collective ownership structures often prevent individuals from using land as collateral for institutional loans.

Youth Migration

Educated tribal youth increasingly migrate toward urban centres and market-driven employment opportunities.

Administrative Conflicts

Traditional tribal governance institutions sometimes face jurisdictional conflicts with state forest departments and bureaucratic agencies.

Market Pressures

Commercial agriculture and market volatility encourage replacement of diverse traditional crops with monoculture cash crops.

Government Initiatives Supporting TEC

Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act (Forest Rights Act)

Empowers Gram Sabhas to protect and manage community forest resources.

Panchayats (Extension to Scheduled Areas) Act (PESA)

Strengthens tribal self-governance over land, water, forests, and local minerals.

Van Dhan Yojana

Promotes community-based value addition and marketing of minor forest produce.

MSP for Minor Forest Produce

Provides minimum price support to protect tribal gatherers from exploitation by middlemen.

Dharti Aba Janjatiya Gram Utkarsh Abhiyan

Supports tribal infrastructure development while preserving cultural heritage.

Adi Karmayogi Abhiyan

Trains tribal grassroots leaders for participatory governance rooted in indigenous traditions.

Relevance in Contemporary Development

TEC aligns closely with modern concepts such as:

• Sustainable development
• Climate resilience
• Circular economy
• Community-based conservation
• Environmental justice

At a time of climate change, biodiversity loss, and ecological degradation, tribal ecological practices offer important lessons for balancing development with environmental sustainability.

Conclusion

Tribal Ecological Communitarianism presents a holistic development framework rooted in sustainability, collective welfare, and ecological harmony. While challenges related to scalability, modernisation, and market integration remain significant, TEC provides valuable insights for creating inclusive and environmentally sustainable development pathways.

Strengthening tribal rights, protecting indigenous knowledge, and integrating community-led

conservation into national policies can contribute significantly to climate resilience and ecological security.

The latest findings from the World Database on Protected and Conserved Areas (WDPCA) highlight both progress and persistent gaps in global marine conservation efforts. According to recent data, nearly 10% of the world’s oceans are now under some form of protection, marking an increase of 1.41% since 2024. However, experts warn that current conservation efforts remain insufficient to achieve global biodiversity targets under the Kunming-Montreal Global Biodiversity Framework (KMGBF).

The report underscores the urgent need for stronger marine governance, protection of high seas biodiversity, and expansion of highly protected marine ecosystems.

About WDPCA

The World Database on Protected and Conserved Areas is a joint initiative of:

• United Nations Environment Programme (UNEP)
• International Union for Conservation of Nature (IUCN)

It is managed by the UNEP World Conservation Monitoring Centre (UNEP-WCMC) based in Cambridge.

Objectives

The database:

• Tracks terrestrial and marine protected areas globally
• Monitors progress toward biodiversity conservation goals
• Supports implementation of the Kunming-Montreal Global Biodiversity Framework

Monthly Updates

The WDPCA is updated monthly to reflect:

• Newly designated protected areas
• Changes in conservation status
• Governance and management updates

Key Findings on Marine Conservation

Global Marine Protection Reaches 10%

Around 10.01% of the global ocean is now covered under protected and conserved areas.

This represents progress compared to previous years but remains significantly below the global “30×30” target.

Importance of High Seas

The report highlights that:

• Around 95% of Earth’s habitable space by volume lies within the oceans and high seas.

Despite their ecological importance:

• Only 1.66% of high seas areas beyond national jurisdiction are currently under conservation management.

This reflects a major governance and conservation gap.

Largest Marine Protected Area

In 2025, Tainui Atea became the world’s largest Marine Protected Area (MPA), covering around 4.5 million square kilometres.

The creation of such mega-MPAs demonstrates increasing global recognition of ocean conservation priorities.

The 30×30 Global Target

Under the Kunming-Montreal Global Biodiversity Framework, countries committed to conserving:

• 30% of the Earth’s land and oceans by 2030.

Current marine protection levels indicate that:

• Ocean protection must nearly triple within this decade to achieve the target.

Quality of Protection Remains Weak

A major concern highlighted by WDPCA is that only:

• Around 2.8%–3.3% of oceans are categorised as “fully or highly protected.” In such zones:
• Industrial fishing
• Deep-sea mining
• Extractive activities

are either heavily restricted or completely prohibited.

Thus, mere designation of protected areas does not always ensure effective biodiversity conservation.

Key Biodiversity Areas (KBAs)

The report also highlights conservation gaps concerning Key Biodiversity Areas (KBAs).

What are KBAs?

Key Biodiversity Areas are ecologically important sites that contribute significantly to the persistence of global biodiversity.

Existing Gaps

Around:

• 30%–34% of identified marine KBAs still lie outside protected or conserved areas.

This exposes vulnerable ecosystems and species to overexploitation and habitat degradation.

Relation with Global Biodiversity Targets

Aichi Biodiversity Targets

Target 11 of the Aichi Biodiversity Targets (2011–2020) aimed to conserve at least 10% of coastal and marine areas.

Although the world has now crossed this threshold, conservation experts argue that:

• Quantity alone is insufficient
• Effective management and ecological representation are equally important

Challenges in Marine Conservation

Weak High Seas Governance

Areas beyond national jurisdiction lack strong enforcement mechanisms.

Overfishing and Deep-Sea Exploitation

Industrial fishing and emerging deep-sea mining activities threaten marine ecosystems.

Climate Change

Ocean warming, acidification, and coral bleaching continue to damage marine biodiversity.

Limited Enforcement Capacity

Several marine protected areas exist only “on paper” without effective monitoring or implementation.

Way Forward

Expand Highly Protected MPAs

Increase strict no-take marine reserves with stronger ecological safeguards.

Strengthen BBNJ Agreement Implementation

Operationalise the Biodiversity Beyond National Jurisdiction Agreement for high seas governance.

Improve Scientific Monitoring

Use satellite tracking, AI, and marine biodiversity mapping for effective conservation.

Promote International Cooperation

Marine ecosystems are transboundary in nature and require collaborative governance frameworks.

Conclusion

The WDPCA findings reveal that global marine conservation is progressing but remains far below the scale required to protect ocean ecosystems effectively. While crossing the 10% threshold is an important milestone, achieving the 30×30 target will require rapid expansion of protected areas, stronger enforcement, and improved protection quality. Sustainable ocean governance is essential not only for biodiversity conservation but also for climate stability, food security, and the future of the blue economy.

The Kuala Lumpur Declaration on Climate Justice was issued ahead of COP31 and the Santa Marta Conference, highlighting the urgent need for climate justice and accelerated climate action in the Global South. The declaration was adopted by civil society organisations, environmental activists, and climate experts from South and Southeast Asia.

The declaration emerged against the backdrop of rising geopolitical conflicts, energy insecurity, and continued dependence on fossil fuels. It argues that developing countries are disproportionately affected by climate change despite contributing minimally to global emissions.

Key Demands of the Declaration

1. Fossil Fuel Phase-Out

The declaration calls for a clear and time-bound global roadmap to phase out coal, oil, and gas in an equitable manner.

It stresses that developed nations, being historically responsible for higher emissions, should take the lead in reducing fossil fuel dependence while supporting developing economies in transition.

2. Climate Finance

A major demand is enhanced climate financing for developing countries.

• Estimated requirement: $5.1–6.8 trillion by 2030
• Long-term demand: $5 trillion annually

The declaration argues that climate finance should be:

• Adequate,
• Predictable,
• Grant-based rather than debt-driven.

3. Fossil Fuel Treaty

The declaration advocates a legally binding global Fossil Fuel Non-Proliferation Treaty to complement the Paris Agreement.

The proposed treaty seeks to:

• Halt new fossil fuel expansion,
• Gradually phase out existing production,
• Ensure a fair transition toward renewable energy.

4. Just Transition

The declaration promotes a people-centric “just transition” framework. It emphasises protecting:

• Workers dependent on fossil fuel industries,
• Indigenous communities,
• Women and youth,
• Climate-vulnerable populations.

The focus is on balancing environmental sustainability with social justice and livelihood security.

5. Adaptation and Loss & Damage

The declaration calls for:

• Tripling adaptation finance,
• Strengthening the Loss and Damage Fund for climate-hit nations.

Developing countries argue that they require greater support to tackle extreme weather events, sea-level rise, droughts, and displacement.

Conference of the Parties (COP)

United Nations Framework Convention on Climate Change COP meetings are annual global climate summits where countries negotiate measures related to emissions reduction, adaptation, and climate finance.

COP31 is scheduled to be held in Antalya in November 2026.

Significance

The Kuala Lumpur Declaration reflects the growing assertion of the Global South in climate negotiations. It highlights the need for climate equity, financial responsibility of developed countries, and a faster transition away from fossil fuels while safeguarding developmental priorities.

India, with a coastline of over 7,500 km and a vast Exclusive Economic Zone (EEZ), possesses rich marine biodiversity comprising coral reefs, mangroves, seagrasses, marine mammals, turtles, and deep-sea ecosystems. Recognising the ecological and economic importance of oceans, India has adopted a mission-mode approach toward marine conservation through legal safeguards, institutional mechanisms, and scientific initiatives such as the Deep Ocean Mission (DOM).

The framework reflects India’s commitment toward sustainable use of marine resources, biodiversity protection, and strengthening the blue economy.

Legal and Institutional Framework

Wildlife Protection Measures

The Wildlife (Protection) Act, 1972 provides legal protection to several marine species under Schedules I and II.

The 2022 amendment strengthened enforcement by granting the Indian Coast Guard powers of search, seizure, and arrest in marine wildlife crime cases.

Marine Protected Areas (MPAs)

India has established 132 Coastal and Marine Protected Areas, including:

• 6 Marine National Parks
• Marine sanctuaries
• Protected mangrove and coral ecosystems These protected areas help conserve:
• Coral reefs
• Mangroves
• Seagrass beds
• Marine fauna and breeding habitats

Scientific Institutions

The Centre for Marine Living Resources and Ecology (CMLRE) plays a major role in marine biodiversity assessment.

It uses advanced tools such as environmental DNA (eDNA) metabarcoding to monitor deep-sea biodiversity and maintain a national marine fauna repository.

Deep Ocean Mission (DOM)

Launched in 2021 under the Ministry of Earth Sciences, the Deep Ocean Mission aims to explore ocean resources and develop technologies for sustainable deep-sea operations.

Samudrayaan Mission

A flagship component of DOM is the Samudrayaan project, which seeks to undertake India’s first human deep-sea mission to a depth of 6,000 metres.

The mission will use the Matsya 6000 submersible capable of carrying a three-member crew.

Technological Significance

Matsya-6000 uses a titanium-alloy spherical hull developed with support from Indian Space Research Organisation (ISRO), enabling survival under extreme underwater pressure.

Resource Exploration

The mission focuses on exploring polymetallic nodules in the Central Indian Ocean Basin containing:

• Cobalt
• Nickel
• Copper
• Manganese

These minerals are strategically important for renewable energy technologies, batteries, and electronics manufacturing.

Strategic Importance

Successful implementation would place India among a select group of countries — including the United States, Russia, China, France, and Japan — possessing human deep-sea exploration capabilities.

Other Major Conservation Initiatives

Project Dolphin

Launched in 2020, the project focuses on habitat conservation and population monitoring of both marine and river dolphins.

National Marine Turtle Action Plan

Introduced in 2021, the plan seeks to conserve Olive Ridley turtles by reducing fishing-related threats and coastal poaching.

Integrated Coastal Zone Management (ICZM)

ICZM promotes sustainable coastal development and resource management in states such as:

• Gujarat
• Odisha
• West Bengal

MISHTI Scheme

Launched in 2023, MISHTI promotes mangrove restoration across 13 states and Union Territories, covering over 22,000 hectares.

BBNJ Agreement

India joined the Biodiversity Beyond National Jurisdiction Agreement (BBNJ) in 2024 to support conservation of marine biodiversity in areas beyond national jurisdiction.

Challenges

Despite significant progress, several challenges persist:

• Marine pollution and plastic waste
• Coastal erosion and habitat degradation

Beyond scientific significance, these fireflies serve as indicators of healthy ecosystems and remind us of the urgent need to conserve fragile forest habitats amid growing environmental pressures.

Protecting such species is essential not only for biodiversity conservation but also for preserving ecological balance and understanding the complex evolutionary processes of nature.

Context

The push for 100% ethanol blending (E100) has gained momentum after the Union Minister for Road Transport and Highways advocated its adoption as part of India’s broader strategy for energy self-reliance and reduced dependence on fossil fuel imports. While India has made significant progress in ethanol blending, moving towards E100 raises important

technological, economic, and environmental considerations.

Understanding Ethanol Blending (E100)

Ethanol blending involves mixing ethanol with petrol. E100 refers to the use of pure ethanol as fuel. However, ethanol has a lower energy density than petrol—approximately 45–55% less energy per litre—which directly impacts mileage and vehicle performance.

Currently, most vehicles in India are compatible with E20 (20% ethanol blend) or lower. Higher blends such as E85 or E100 require flex-fuel vehicles (FFVs) that can operate on varying ethanol-petrol mixtures.

Need for Flex-Fuel Vehicles (FFVs)

Transitioning to E100 requires a shift in automobile technology. FFVs are equipped with:

• Corrosion-resistant fuel systems
• Advanced sensors and engine control units
• Optimised combustion systems for ethanol

Countries like Brazil have successfully adopted FFVs at scale. In India, adoption is still nascent, though companies like Toyota are introducing compatible models, and others such as Maruti Suzuki and Hyundai are developing prototypes.

Infrastructure and Supply Chain Requirements

Achieving E100 is not merely a technological challenge but also an infrastructural one. It requires:

• Dedicated storage and distribution systems
• Modifications in fuel stations
• Efficient logistics for ethanol transport

These changes must align with India’s broader push for domestic manufacturing and energy transition.

Ethanol Production in India: Opportunities and Challenges

India primarily produces ethanol from sugarcane, making it the dominant feedstock. While this supports the agricultural economy, it raises concerns:

• Sugarcane is water-intensive
• Cultivation often occurs in water-stressed regions
• Potential impact on food security and crop prices

Shift Towards Second-Generation (2G) Ethanol

To address sustainability concerns, India is promoting 2G ethanol, produced from crop residues like rice straw.

Benefits include:

• Reducing stubble burning in North India
• Lower environmental impact
• Diversification of feedstock sources

Public sector entities like Indian Oil Corporation are actively investing in 2G ethanol plants.

Cost and Policy Support

Ethanol production is often costlier or comparable to petrol, requiring government intervention through:

• Administered pricing
• Subsidies and incentives
• Policy support for industry expansion

Without such measures, large-scale adoption may not be economically viable.

Environmental Trade-offs

Ethanol is often seen as a cleaner alternative, but its environmental impact is mixed:

Advantages:

• Lower emissions of carbon monoxide
• Reduced particulate matter

Concerns:

• High water consumption
• Land use changes
• Increased use of fertilisers and pesticides

Thus, sustainability depends on production practices rather than fuel use alone.

CAFE Norms and Ethanol Blending

India introduced Corporate Average Fuel Efficiency (CAFE) norms in 2017 to regulate vehicle emissions.

• CAFE I (2017) and CAFE II (2022) improved fuel efficiency
• CAFE III (2027) will impose ~30% stricter emission targets

While CAFE norms do not mandate ethanol use, they indirectly incentivise higher ethanol blends as automakers seek to meet emission targets.

Consumer Concerns and Efficiency

Ethanol-blended fuels present challenges for consumers:

• E20 fuel reduces mileage by 6–7%
• Higher blends may further reduce efficiency
• Potential increase in fuel costs

Adoption will depend on balancing affordability, efficiency, and environmental benefits.

Progress of Ethanol Blending in India

India’s Ethanol Blending Programme (launched in 2003) has seen rapid progress:

• ~2% blending in 2014
• Achieved E10 by 2022
• E20 rollout from 2023, targeted nationwide by 2025 This accelerated progress reflects strong policy support.

Infrastructure and Industry Challenges

Despite progress, key bottlenecks remain:

• Limited vehicle compatibility
• Inadequate fuel storage and distribution systems
• Supply constraints of ethanol

These challenges must be addressed before scaling up to E100.

Ethanol and India’s Energy Security Strategy

Ethanol blending is part of a broader strategy to reduce import dependence. However, India is also exploring:

1. Diversification of Energy Sources
   • Alternative oil suppliers
   • Expansion of renewable energy
2. Hydrogen Economy

Under the National Green Hydrogen Mission, India aims to:

• Produce hydrogen at $1/kg
• Compete with fossil fuels
• Become a global energy exporter

3. Circular Economy Approach
   • Producing hydrogen from municipal waste and sewage
   • Integrating sustainability with energy production

Challenges in Energy Transition

• Limited domestic production of oil and gas
• Technological gaps in hydrogen storage and transport
• Infrastructure constraints
• Geopolitical uncertainties

Way Forward

• Promote sustainable feedstocks like 2G ethanol
• Expand FFV adoption and infrastructure
• Balance environmental and economic considerations
• Integrate ethanol strategy with broader clean energy goals

Conclusion

Ethanol blending represents a significant step towards energy security and cleaner fuels in India. However, achieving 100% blending requires overcoming challenges related to technology, infrastructure, cost, and sustainability. A balanced and phased approach—

combined with innovations like green hydrogen—will be crucial for India’s long-term energy transition.

The Himachal Pradesh High Court recently quashed a notification that declared areas of at least three gram panchayats around Col. Sher Jung National Park as an Eco-Sensitive Zone (ESZ). The decision has raised important questions regarding environmental governance, conservation policies, and the balance between ecological protection and local livelihoods.

About Col. Sher Jung National Park

  Col. Sher Jung National Park, also known as Simbalbara National Park, is located in the Paonta Valley of Himachal Pradesh along the border with Haryana.

  It is named after Colonel Sher Jung, a noted freedom fighter and environmentalist.

  The park lies in the Shiwalik range, with elevations ranging from 350 to 700 meters above sea level.
