e-Shram Portal Completes Five Years

GS Paper II – Governance | Social Justice | Welfare Schemes

Why in News?

The e-Shram portal, launched in August 2021, has completed five years of operation.

Background

India's workforce has historically been dominated by the unorganised sector, comprising workers who often lack formal employment contracts and adequate social-security coverage.

Core Objective

• Create a centralised database of unorganised workers.
• Provide workers with a Universal Account Number (UAN).
• Facilitate access to government welfare schemes.
• Improve portability of benefits for migrant workers.
• Enable better policy formulation using worker-level data.

Why is it important?

The major problem with welfare delivery is not always the absence of schemes, but identification and last-mile delivery.

e-Shram attempts to solve this through:

Worker identification → Database creation → Scheme convergence → Benefit delivery

Significance

• Social-security inclusion : It helps bring informal workers into the formal welfare architecture.
• Migrant worker portability : A worker migrating from one State to another can potentially remain within a common welfare database.
• Scheme convergence : Different welfare programmes can be linked to a common beneficiary database.
• Better policymaking : Data can help governments understand the occupational and geographical distribution of informal workers.

Challenges

• Digital Divide: Limited internet access and digital literacy hinder registration.
• Outdated Information: Worker details may become incorrect due to migration or job changes.
• Worker Mobility: Frequent movement makes it difficult to track and update worker records.
• Lack of Awareness: Many workers are unaware of e-Shram registration and its benefits.
• Data Privacy: Large-scale worker data creates risks of data leaks and cyberattacks.
• Benefit Delivery Gap: Registration alone does not ensure access to welfare schemes.

Way Forward

• Regular Database Updation: Periodically verify and update worker details.
• State Integration: Link e-Shram with State-level worker databases for better coverage.
• Multilingual Registration: Provide local-language and assisted registration facilities.
• Privacy Safeguards: Strengthen data protection, encryption and cybersecurity.
• Scheme Convergence: Integrate e-Shram with more social-security and welfare schemes.
• Grievance Redressal: Establish quick and accessible mechanisms to resolve worker complaints.

Hijab & Essential Religious Practices Doctrine

GS Paper II – Indian Polity | Fundamental Rights

Why in News?

Judicial observations on whether wearing the hijab qualifies as an Essential Religious Practice (ERP) have revived the debate over Article 25 and the limits of judicial scrutiny of religious practices.

Constitutional Framework

• Article 25 : Guarantees freedom of conscience and the right to profess, practice and propagate religion.
• Not absolute — subject to: Public order , Morality, Health.

Essential Religious Practices (ERP) Doctrine

• A judge-made doctrine used to determine which religious practices receive constitutional protection.
• Key question: Is the practice essential to the religion, or merely associated with it?
• Courts have historically examined religious texts, traditions and practices to make this determination.

Core Constitutional Tension

Religious Freedom ↔ Equality ↔ Individual Autonomy ↔ Institutional Discipline

Why Controversial?

• Critics: Courts should not decide theological questions or determine what is essential to a religion.
• Supporters: Constitutional courts must determine whether claimed religious practices are protected by Fundamental Rights.

Broader Significance

• Secularism: Balancing state neutrality with religious freedom.
• Equality: Preventing discriminatory practices.
• Constitutional Morality: Giving primacy to constitutional values.
• Individual Dignity: Protecting personal choice and autonomy.
•  Institutional Autonomy: Allowing reasonable rules in educational/work institutions.

Way Forward

• Protect genuine religious freedom while respecting constitutional limits.
• Minimise theological adjudication where possible.
• Balance religious claims with equality and dignity.
• Permit reasonable, proportionate institutional regulations.
• Apply constitutional principles consistently, irrespective of the religion involved.

Nepal Flash Floods

GS I – Geography|GS III –Disaster management

Why in News?

On 26 August 2026, a catastrophic flash flood struck Nepal’s Rasuwa district near the Nepal–Tibet border.. The event affected the Lhende Khola–Bhote Koshi river system and caused extensive damage to settlements and infrastructure.

What is a Flash Flood?

A flash flood is a rapid rise of water in rivers, streams or low-lying areas, generally occurring within a short period after intense rainfall or a sudden release of water.

Major triggers

• Cloudburst/extreme rainfall
• Glacial Lake Outburst Flood (GLOF)
• Glacier collapse
• Landslide-dammed lake failure
• Sudden snow/ice avalanche
• Dam or reservoir failure

What Happened in Nepal?

• The disaster occurred in the steep Himalayan terrain of Rasuwa district.
• A major ice-rock avalanche/glacial collapse entered the river system, producing a sudden surge of water and debris. Reports indicate that river levels rose dramatically within a very short period, destroying roads, bridges, settlements and other infrastructure.

Why is Nepal Highly Vulnerable?

• Nepal lies almost entirely within the Himalayan mountain system, with steep slopes, fragile geology and intense monsoon rainfall.

Fragile Himalayan geology

The Himalayas are:

• Young fold mountains
• Tectonically active
• Characterised by unstable slopes
• Vulnerable to landslides and rockfalls

Steep topography : Water moves rapidly down narrow mountain valleys.

Therefore: Steep slope + confined valley + sudden water release = high flood velocity

Monsoon rainfall

Nepal receives intense rainfall during the June–September southwest monsoon.

Nepal and India share several transboundary river systems.

Important rivers include:

• Koshi
• Gandaki/Narayani
• Karnali
• Mahakali

Infrastructure Vulnerability

• Roads → Landslides & debris flows: Mud, rocks and floodwater can block or wash away roads, cutting off villages.
• Bridges → Scouring: Fast-flowing floodwater can erode the soil around bridge foundations, weakening or damaging bridges.
• Hydropower → Sedimentation & flood damage: Mud and stones carried by floods can fill reservoirs and damage power equipment.
• Transmission lines → Landslide & flood damage: Floods and landslides can damage electricity towers and interrupt power supply.
• Tourism → Risk to trekkers & pilgrims: Floods can damage trekking routes, roads and hotels, putting tourists at risk.
• Border infrastructure → Connectivity & trade: Damage to roads and bridges can disrupt movement of people and goods across border areas.

Major Challenges

• Limited warning time : A glacier collapse can occur suddenly, leaving extremely little time for evacuation.

Difficult terrain : Mountainous terrain makes

• Road access difficult
• Helicopter operations challenging
• Communication unreliable
• Rescue operations slow
• Fragmented monitoring

Cryosphere, rainfall, river discharge and seismic information need to be monitored together.

Transboundary nature

• The source and downstream impacts can involve Nepal, China and India, requiring international coordination.

Infrastructure concentration

• Roads, hydropower projects and settlements are often concentrated along narrow valleys.

Way Forward

Strengthen Early Warning Systems

• Develop integrated monitoring of: Glaciers, Glacial lakes, River discharge, Rainfall, Landslides, Seismic activity
• Use: Satellite + GIS + remote sensing + ground sensors + AI-based forecasting

Transboundary Data Sharing

• India, Nepal and China should strengthen: Real-time rainfall data sharing, River-level information, Glacier monitoring, Flood alerts, Emergency communication

Hazard Zonation

• Prepare detailed maps identifying: GLOF-prone zones, Landslide-prone slopes, Flash-flood corridors, Debris-flow zones, Glacier-collapse risk zones.

• Public Procurement: Bulk procurement can lower costs.
• Health Insurance: Provides financial protection.
• Public Cancer Centres: Expand affordable treatment infrastructure.
• Domestic R&D: Promote innovative medicines, biosimilars and diagnostics.

Way Forward

• Prevention → Early Detection → Affordable Treatment
• Strengthen cancer screening.
• Expand health insurance and public healthcare.
• Promote generic/biosimilar competition.
• Strengthen domestic pharmaceutical R&D.
• Use Health Technology Assessment (HTA) for evidence-based healthcare spending.

Waterspout

GS Paper I – Physical Geography | Disaster Management

Why in News?

A rare rotating column of air and water was observed over the Brahmaputra River in Assam.

What is a Waterspout?

• A rotating column of air extending from a cloud toward the surface of a water body.
• It often appears as a funnel-shaped cloud connecting the water surface with the cloud base.

It is broadly similar to a tornado occurring over water.

Types

Fair-Weather Waterspout

• Usually develops in relatively less severe atmospheric conditions.
• Generally weaker and shorter-lived.

Tornadic Waterspout

• Associated with severe thunderstorms.
• Forms in association with a rotating thunderstorm.
• Can be stronger and more destructive.

Formation of Waterspout

• Warm Water Surface : Warm water heats the air immediately above it.
• Moist Air : Evaporation adds moisture to the lower atmosphere.
•  Atmospheric Instability : Warm, moist air becomes buoyant and rises rapidly.
• Convection : Rising air creates strong upward convection beneath a cloud.
• Rotation : Suitable changes in wind speed/direction with height can help develop rotation.
• Funnel Formation : As air pressure falls and moisture condenses, a visible funnel-shaped cloud develops.
• Waterspout : The rotating funnel extends down to the water surface, forming a waterspout.
