Revision summary
Human security after UNDP 1994 centres people, not only territorial defence. Climate, pollution, water stress, and ecosystem loss kill and displace without a foreign army. Bay of Bengal cyclones, Pakistan 2022 floods, and urban air are South Asian exhibits. COVID-19 linked ecology, health, and later vaccine rules. Realist State security remains relevant for war; it is incomplete for this class of threat.
Model answer
Introduction
Human security, as used after the UNDP Human Development Report of 1994, is safety of people in daily life, not only safety of States from invasion. Environmental degradation now produces that insecurity through water, food, disease, and disaster, including in South Asia.
Body
From State security to human security
- Traditional realism, including Waltz, ranked military threats first. Environmental harm was a domestic or scientific issue.
- Human security treats drought, flood, pollution, and epidemic as security problems because they kill, displace, and break livelihoods.
- Robert Cox’s critical theory helps here: an order that protects capital and great-power stability can still leave people exposed to climate and toxic risk.
How degradation produces insecurity
- Climate change raises heat, cyclone intensity, and glacier melt, which hit farming and coastal cities.
- Deforestation, mining, and air pollution raise respiratory disease and destroy commons that the poor use.
- Water stress between upstream and downstream users, including India–Pakistan Indus politics and India–China Brahmaputra concern, can feed diplomatic conflict.
- Loss of fisheries and soil pushes migration, which then appears as a border and urban security issue.
Examples
- Cyclones in the Bay of Bengal, including events that have struck Odisha, West Bengal, and Bangladesh, show how a “natural” disaster is worsened by degraded mangroves and dense coastal poverty.
- The 2022 Pakistan floods linked monsoon extremes, river management, and mass displacement.
- Delhi’s seasonal air quality is a public-health emergency that no army can treat as a foreign enemy.
- COVID-19 showed how ecological disturbance and global travel can create a health-security shock; vaccine nationalism then appeared at the WTO, treated in Section B.
- Sahel drought and farmer–herder conflict show the same chain in Africa, which also shapes India’s development diplomacy there.
Policy implication
- Mitigation, adaptation, disaster management, and climate finance are security policy in this frame, not extras after defence.

Conclusion
Environmental degradation is a major source of human insecurity because it destroys health, food, water, and shelter at scale. Examples from South Asian floods and storms, urban air, and global disease show that State military balance does not measure this threat.

-
Is climate change a replacement for military security?
No. It is an added source of insecurity. States still face armies. People also face heat, flood, and toxic air.
-
Can the Security Council treat climate as a threat to peace?
Members have debated it. P5 disagreement and sovereignty claims have limited a standing Chapter VII climate practice.

What are the crucial functions of empirical political theory in Comparative Politics?
Comparative Politics
Empirical political theory studies observable political facts with concepts that evidence can test. Its functions are description, classification, explanation, middle-range theory, and checking claims against practice. It shifted Comparative Politics from legal texts alone toward behaviour and institutions. Sartori’s warning against conceptual stretching is part of that discipline. It does not cancel culture or critical theory; it supplies the evidence those approaches still need.
Q1(b) · UPSC Mains 2023 · PSIR GS 2 · 10 marks
What are the difficulties faced by a political theorist in comparing the States?
Comparative Politics
States are unlike in size, history, and capacity, so the unit of comparison is not automatic. Conceptual stretching, Galton’s problem, and selection bias are standard difficulties. Data are political products, and language changes the meaning of institutions. Interdependence means States are not independent experiments. Designs such as most-similar cases reduce error; they do not remove it.

How does democratic politics construct citizenship?
Comparative Politics
Citizenship in a democracy is made by law, votes, and social rights, not only by birth records. Marshall’s civil, political, and social rights describe how that status has thickened. Parties, movements, and civic education teach people to act as citizens. Democracies still contest migrants, minorities, and documents of belonging. Construction is therefore both inclusion and a fight over who is inside.
