{GS1 – Geo – PG –Geomorphology} Mud Volcano

Context (LS): The Wandan mud volcano in Taiwan recently erupted.

What are Mud Volcanoes?

Mud Volcanoes are landforms formed by the eruption of mud, water, and gases, rather than molten rock. Eruptions of mud volcanoes are generally cool, unlike magmatic volcanoes.
They do not involve lava or magma. They emit methane, CO₂, and nitrogen, often under high pressure.
Some remain constantly active, while others experience periodic bursts.
Despite lower explosiveness, they can trigger fires.

Why Flames Occur?

Hydrocarbon gases like methane may ignite naturally from surface heat or deliberately by human action, e.g., Wandan volcano flames resulted from locals burning ejected methane gas after eruptions.
Gas movement through fractures may ignite due to friction between rocks.
Electrical discharges from gas clouds can ignite flammable methane plumes.

Types of Mud Volcanoes

Cold Mud Volcanoes: These emit cool mud and gases and do not involve geothermal heating.
Hot Mud Volcanoes: They cause warmer emissions, linked to subduction zones & geothermal activity.
Island Mud Volcanoes: These emerge offshore and may form temporary mud islands.
Onshore Cone Domes: They have dome-shaped mud features common in petroleum-rich sedimentary basins.

Mud Volcanoes vs Regular Volcanoes

Eruption Material: Mud volcanoes emit mud and gas; regular volcanoes release lava and ash.
Heat Source: Mud volcanoes involve surface gases; regular volcanoes arise from mantle magma.
Explosiveness: Regular volcanoes are explosive; mud volcanoes erupt under low pressure.
Geological Depth: Mud volcanoes are shallow phenomena; regular ones stem from deep crust.
Hazard Type: Mud volcanoes cause fire and subsidence; regular ones trigger lava flows.

{GS2 – IR – Groupings} India’s Strategic Pivot with BRICS

Context (IE): Amid rising geopolitical uncertainty and a retreating U.S., India is recalibrating its foreign policy by deepening multilateral ties like BRICS.

Strategic Relevance of BRICS

Global Weight: With 11 member countries, BRICS represents nearly 50% of the world’s population and about 40% of global GDP.
Diverse Yet Cohesive: Unlike the ideologically aligned G7, BRICS brings together nations with varied political systems and economic models making it both resilient and complex.
Multilateral Shield: In an era marked by U.S. retreat from global leadership and weakening of institutions like WTO & WHO, BRICS offers its members strategic autonomy & a collective bargaining platform.
South-South Solidarity: It strengthens cooperation among developing nations, boosts global standing, and presents an alternative vision of global governance amid a shifting multipolar order.

Key Developments at the 2025 Rio Summit

Increased Representation: The first BRICS Summit post-2024 expansion brought new Global South members onboard, enhancing inclusivity but complicating consensus due to diverse national agendas.
Geopolitical Assertion: BRICS condemned Israel’s attack on Iran as a violation of international law. India’s endorsement signalled a strategic shift towards greater foreign policy autonomy.
Global Governance: Key themes included ethical AI, climate change, health, and governance reforms, areas where BRICS is filling the vacuum left by Western disengagement.
De-dollarisation: While a joint currency remains off the table, members are increasing trade in national currencies and promoting non-dollar benchmarks, signalling financial independence.
India’s Strategic Balancing: India continues to walk a tightrope, maintaining ties with the US while reinforcing BRICS as a platform for promoting multipolarity and addressing global development challenges.

Strategic Implications for India

Diplomatic Autonomy: India’s active participation reaffirms its commitment to multi-engagement foreign policy, resisting pressure from Western powers.
Global South Leadership: India’s alignment with BRICS on contentious geopolitical issues enhances its credibility as a voice of the Global South.
Economic Diversification: Strengthening trade in national currencies and financial independence within BRICS opens avenues for reducing overdependence on the US dollar.

Way Forward for India

Promote Complementarity, Not Competition: India should continue balancing its role in BRICS alongside Western forums like the G20, Quad, and G7 to leverage diverse strategic platforms.
Shape Global Governance: Use BRICS to influence emerging global rules on issues such as technology, climate change, financial architecture, and development equity.
Amplify Voice of the Global South: Champion collective South-South cooperation to address common challenges like terrorism, energy transition, digital inclusion, and healthcare access.

{GS2 – IR – Issues} Rephasing Global Development Finance

Context (TH): With shrinking global development finance and rising geopolitical tensions, India is strategically pivoting by deepening Global South ties and promoting Triangular Cooperation to reshape the aid architecture.

Declining Development Finance

Sharp Drop in ODA: Global Official Development Assistance (ODA) is projected to fall from $214 billion in 2023 to $97 billion, marking a 45% decline.
Sovereign Debt Stress: Many least developed and middle-income countries are experiencing debt distress, making credit-based aid models riskier and implementation of development programmes harder.
Higher Cost of Borrowing: Increased borrowing costs have made financing development more unpredictable and expensive for vulnerable nations.
SDG Investment Gap: The financing needed to meet the Sustainable Development Goals (SDGs) has surged from $2.5 trillion in 2015 to over $4 trillion in 2024, widening the development finance gap.

Triangular Cooperation: A Strategic Solution

Triangular Cooperation (TrC) is a collaborative development model. It aims to deliver inclusive development by combining technical expertise, local knowledge, and financial resources. It involves:
- A traditional donor from the Global North.
- A pivotal partner from the Global South (e.g., India).
- A recipient country in the Global South.
Key Objectives: To promote South-South solidarity, enable inclusive and need-based growth, and leverage the strengths of multiple stakeholders for greater development impact.

India’s Strategic TrC Engagements

During its G20 Presidency, India emphasised TrC through multilateral and bilateral platforms:
- India-Germany TrC projects across Africa and Latin America.
- Global Innovation Partnership (GIP) with the United Kingdom, promoting sustainable development innovations in third countries.
- Trilateral dialogues with Germany, the EU, France, and the US, exploring investment-driven and grant-based cooperation.

Significance of Triangular Cooperation (TrC)

Bridges North-South Divide: TrC promotes equitable partnerships rooted in mutual respect rather than donor-recipient hierarchies.
Cost-effective and Scalable: Shared financial and technical contributions reduce fiscal stress on any single partner and allow for scaled-up outcomes.
Tackles Social Needs Together: Projects like regional energy grids not only improve infrastructure but also expand digital connectivity and access to education and healthcare.

Way Forward for India

India must deepen its engagement in TrC to remain a credible development partner. This includes:

Mapping complementary strengths with like-minded nations (e.g., Japan, Brazil, Indonesia).
Prioritising localised and inclusive development strategies.
Balancing all five modalities of engagement under the Global Development Compact.
Institutionalising frameworks to implement, monitor, and evaluate TrC outcomes.

Context (TH): As per The Lancet (2023), India has 1.44 million zero-dose children the world’s second highest after Nigeria, underscoring a critical immunisation gap that endangers both individual and public health.

Who Are Zero-Dose Children?

As per WHO, a zero-dose child is one under the age of one who hasn’t received any routine vaccination.
These children face greater lifetime risk of vaccine-preventable diseases such as measles, polio, and diphtheria.

Why It Matters?

Threat to Herd Immunity: Zero-dose children weaken community-wide protection, hindering disease elimination efforts.
Post-COVID Spike: Pandemic-related disruptions led to a sharp rise in zero-dose cases; while recovery has begun, coverage still lags pre-pandemic levels.
Beyond the Metric: The zero-dose figure excludes partially vaccinated or older unvaccinated children, an unseen, equally at-risk population

Structural Gaps and Challenges

Geographic Clustering: Zero-dose children are concentrated in urban slums, conflict zones, and remote communities. These clusters lack not only vaccines but also essential public health services like nutrition and sanitation.
Access and Awareness: Many parents, especially in vulnerable communities, are unaware of routine immunisation schedules. Some are unable to take time off work or travel to health centres.
Documentation Barriers: The digital UWIN platform faces inclusivity challenges, as it often requires mobile access and identification documents like Aadhaar, items many marginalised families lack.
Post-Pandemic Recovery: Routine vaccinations were sidelined during COVID-19, and the system still struggles to bring immunisation levels back to pre-pandemic standards.

Policy Interventions

Mission Intensified Indradhanush: This initiative has focused on expanding routine immunisation in vulnerable districts through targeted campaigns.
Catch-up Vaccinations: Programmes are now designed to immunise older children who missed early doses.
Door-to-Door Drives: Health workers in states like those in the North-East are reaching children in weekly markets and remote areas.
Zero-Dose Implementation Plan: Focused on 143 vulnerable districts across 11 states.

Way Forward

To achieve the WHO’s 2030 target of halving zero-dose children, India should:

Strengthen Last-Mile Delivery: Improve outreach in marginalised, remote, and underserved areas.
Broaden Catch-Up Efforts: Include older unvaccinated and partially vaccinated children, not just infants.
Holistically Integrated: Link vaccination with nutrition, sanitation, maternal care, and health education for greater impact.
Enhance Digital Inclusion: Upgrade platforms like U-WIN to support offline access and undocumented populations.
Drive Community Engagement: Promote awareness through local leaders, schools, and civil society partnerships. Meeting targets is not enough, communities must understand and value vaccines to maintain uptake even after disease prevalence declines.

{GS3 – Envi – Degradation} Jellyfish blooms

Context (DTE): Jellyfish blooms have been reported in Kerala’s Cochin backwaters.

A jellyfish bloom is a sudden, dense aggregation of jellyfish triggered by environmental changes.
It usually occurs in India during April to May and October to December.
Key Bloom Species: Acromitus flagellatus, Blackfordia virginica, Pleurobrachia sp., & Pelagia noctiluca.

Causes for Bloom

Nutrient Enrichment: Runoff-induced eutrophication increases phytoplankton, supporting jellyfish food availability.
Environmental Shift: Rising temperature and pollution reduce oxygen levels, creating conditions where jellyfish thrive but fish decline.
Coastal Currents: Wind, tides, and currents concentrate jellyfish nearshore, increasing their density and triggering blooms.

Kerala’s Distinct Bloom Timing

Unlike other coasts with blooms in April–May & Oct–Dec, Kerala sees longer, shifted bloom periods.
Persistent Salinity: Backwaters stay saline in dry months, supporting off-season blooms.
Weak River Flow: Low summer discharge delays flushing of jellyfish.
Local Mixing: Estuarine tides maintain warm, bloom-friendly conditions beyond usual seasons.

Impacts of Jellyfish Bloom

Fisheries Disruption: Blooms clog nets, damage gear, and drastically reduce fish catch for local fishers.
Tourism Loss: Jellyfish stings and coastal swarms reduce beach tourism and local business revenue.
Ecosystem Dominance: Jellyfish outcompete fish in degraded systems, leading to lower biodiversity.
Biogeochemical Alteration: Blooms accelerate organic matter cycling and modify nutrient flows in coastal waters.

About Jellyfish

Jellyfish are gelatinous, soft-bodied marine invertebrates belonging to the phylum Cnidaria.
They drift passively with ocean currents and cannot actively swim against strong currents.
They occur in tropical, temperate, and polar oceans, and also in brackish estuarine waters.
Jellyfish populations respond rapidly to changes in temperature, salinity, and nutrient levels.

Positive Roles

Plankton Regulation: They feed on zooplankton and larvae, helping control lower trophic levels.
Nutrient Recycling: Decaying jellyfish release organic matter that enhances bacterial activity and nutrient cycling on coasts.
Biochemical Utility: They are being studied for bioactive compounds in the nutraceutical and pharmaceutical industries.
