Cancer Nationally Notifiable Disease: UPSC Editorial Notes

July 4, 2026

Source: The Hindu (Editorial) | Page: 8 | Tags: 4 July 2026, Governance, GS2, Health

Context: Cancer Nationally Notifiable Disease
Cancer cases are projected to rise from 1.41 million in 2022 to 2.46 million in 2045, an increase of around 74%, according to the Global Cancer Observatory.

There is growing demand to make cancer a nationally notifiable disease to strengthen surveillance and evidence-based policymaking.

Present Situation

India has not yet declared cancer as a nationally notifiable disease.

However, 17 States, including Telangana, have already notified cancer under their respective public health laws.

Existing Cancer Data System in India

India currently relies on the National Cancer Registry Programme of the Indian Council of Medical Research.

Types of Registries

Population-Based Cancer Registries

Track cancer cases in defined populations.

Hospital-Based Cancer Registries

Track cancer cases reported in hospitals.

Limitation

These registries cover only around 10–16% of India’s population, leading to incomplete national data.

What Is a Notifiable Disease?

A notifiable disease is a disease that must be reported by:

Hospitals
Laboratories
Registered medical practitioners

to the designated public health authority.

Purpose

Surveillance
Early detection of trends
Public health action
Resource planning
Disease control

Who Can Notify a Disease?

State Governments

States can notify diseases under their respective State Public Health Acts.

This is why States like Telangana have already notified cancer.

Union Government

The Union Government can declare a disease nationally notifiable, making reporting mandatory across all States and Union Territories through a uniform framework.

Advantages of Making Cancer Nationally Notifiable

Creates a comprehensive nationwide cancer database.
Ensures uniform reporting from public and private healthcare facilities.
Helps identify regional cancer hotspots.
Enables better policy formulation.
Improves resource allocation.
Strengthens cancer control programmes.
Supports research and surveillance.
Helps plan screening, diagnosis and treatment infrastructure.

Why It Matters

Cancer care requires strong data because different regions may show different cancer patterns due to:

Lifestyle
Pollution
Tobacco use
Occupational exposure
Genetics
Diet
Healthcare access

Way Forward

Make cancer nationally notifiable.
Strengthen cancer registries.
Ensure mandatory reporting from private hospitals.
Integrate cancer data with digital health systems.
Protect patient privacy.
Improve screening programmes.
Use data for targeted prevention and treatment strategies.

Water Security in India: Challenges & UPSC Editorial Notes

July 4, 2026

Source: The Hindu (Editorial) | Page: 8 | Tags: 4 July 2026, Agriculture, Climate Change, GS3, Water Resources

Context: Water Security in India
Increasing water stress, declining per capita water availability and climate variability have highlighted the need for climate-resilient water governance.

India has only 4% of the world’s freshwater resources but supports nearly 18% of the global population.

Also, 11 of India’s 15 major river basins are already water-stressed.

Water Security

Water security means reliable access to adequate quantity and quality of water for:

Drinking
Agriculture
Industry
Ecosystems
Livelihoods
Disaster resilience

Key Challenges

1. Rising Water Stress

Several river basins have annual per capita water availability below 1,700 cubic metres, making them water-stressed.

Some basins have already crossed the water scarcity threshold of below 1,000 cubic metres per person per year.

2. Groundwater Depletion

Over-extraction of groundwater for irrigation, urban use and industry is worsening water insecurity.

3. Pollution

Industrial waste, sewage discharge and agricultural runoff reduce usable water availability.

4. Erratic Rainfall

Climate change has made rainfall more unpredictable, increasing both drought and flood risks.

5. Infrastructure Gaps

India faces issues such as:

High transmission losses
Poor maintenance of water infrastructure
Inadequate wastewater treatment
Weak storage and distribution systems

6. Governance Gaps

Limited river-basin level data on water use, withdrawals and losses leads to inefficient allocation.

Way Forward

1. Build Climate-Resilient Water Infrastructure

Conduct climate-risk assessment of water projects.
Strengthen urban water systems.
Improve drainage and flood-water management.
Build resilient storage and distribution networks.

2. Improve Water-Use Efficiency

Scale up:

Drip irrigation
Sprinkler irrigation
Treated wastewater reuse
Low water-intensive crops
Efficient industrial water use

3. Strengthen Water Governance

Use:

AI-enabled monitoring
Smart water metering
River-basin water accounting
Real-time data systems
Evidence-based planning

4. Strengthen Flagship Schemes

Improve implementation of:

Jal Jeevan Mission
Pradhan Mantri Krishi Sinchayee Yojana
Climate-resilient agriculture initiatives

5. Promote Crop Diversification

Shift from water-intensive crops to climate-suitable and less water-intensive crops.

6. Reuse and Recycle Wastewater

Treated wastewater can be used for:

Industry
Construction
Landscaping
Agriculture where safe

Significance

Supports drinking water security.
Reduces agricultural vulnerability.
Helps climate adaptation.
Protects groundwater.
Improves urban resilience.
Strengthens food and livelihood security.
