📖 Detailed Notes

Written and reviewed by Subhra Gupta, Humanities faculty at UniDrill (M.A. Sociology, University of Delhi · 7 years teaching Humanities). Based on NCERT Political Science Class XII (Contemporary World Politics), Chapter 6.

Who owns the sky?

Nobody owns the ozone layer, and nobody owns the ice of Antarctica. Yet a factory in one country can thin the ozone over another, and a warming planet floods islands that did not cause it. This is the puzzle of the chapter: when a problem belongs to everyone, who is responsible for fixing it, and who pays? The answer shows up in treaties, in the North versus South divide, and in the exact dates CUET loves to test.

Why did the environment become political?

Environmental issues are no longer left to geographers and naturalists. The planet's life-support systems are under strain, and the symptoms are plain: cultivable land is barely expanding and is losing fertility, grasslands are overgrazed, fisheries are over-harvested, and water is depleted and polluted. Natural forests, which stabilise climate, moderate water supply and shelter most land biodiversity, are being destroyed. The ozone layer in the stratosphere is thinning, which endangers ecosystems and human health. Coastal waters are becoming severely polluted by land-based activities, even though the open sea stays relatively clean.

The human cost is large. According to the UNDP Human Development Report 2016, 663 million people in developing countries lack safe water and 2.4 billion lack sanitation, and more than three million children die each year as a result.

The timeline of environmental politics

Awareness grew from the 1960s. Each step on this ladder built on the one before it.

Year Event Why it mattered
1972 Club of Rome publishes Limits to Growth Dramatised the risk of resource depletion against rising population
1972 onwards UN Environment Programme (UNEP) starts holding international conferences Environment becomes a global agenda
1987 Brundtland Report, Our Common Future Warned that traditional economic growth was not sustainable and gave the term sustainable development its currency
June 1992 Earth Summit at Rio de Janeiro, Brazil The UN Conference on Environment and Development, with 170 states, thousands of NGOs and many MNCs
1992 UNFCCC and the Rio Declaration Climate convention; principle of common but differentiated responsibilities
1997 Kyoto Protocol Greenhouse gas targets for industrialised countries
August 2002 India ratifies the Kyoto Protocol India's participation in the climate regime
2 October 2016 India ratifies the Paris Climate Agreement India's participation in the later regime

What happened at Rio, and why did the North and South disagree?

At Rio, the world's priorities split along the North-South divide. The reasons are easy to follow once you think about interests.

Group Main concern Reasoning
North (First World) Ozone depletion and global warming Treats the environment as a stand-alone problem
South (Third World) The link between development and environmental management Without development, the South cannot afford the environmental investment that the North asks for

The summit still produced conventions on climate change, biodiversity and forestry, and recommended a list of development practices called Agenda 21.

Two views. For the exam: Agenda 21 sets out practices for sustainable development, which the summit endorsed. Another reading: critics, many of them from the South, argued that Agenda 21 favoured economic growth over ecological conservation. Both statements appear in the textbook's account.

The global commons

The global commons are areas outside any single state's sovereign control that need shared governance. The Latin term for the idea, res communis humanitatis, means that they belong to humanity as a whole. There are four.

Global commons Notes
Earth's atmosphere Ozone layer and climate affect everyone
Antarctica Covers about 14 million square km, which is 26 per cent of the world's wilderness, 90 per cent of all land ice and 70 per cent of the planet's fresh water
The ocean floor Outside the control of any one state
Outer space Outside the control of any one state

Cooperation over the commons rests on a few agreements.

Year Agreement Purpose
1959 Antarctic Treaty Limited activity on the continent to scientific research, fishing and tourism
1987 Montreal Protocol Controls substances that deplete the ozone layer; the ozone hole over Antarctica was discovered in the mid-1980s
1991 Antarctic Environmental Protocol Strengthened the environmental protection of Antarctica

Pause and predict: Tropical rainforests are vital to the whole planet's climate. Are they part of the global commons?

Check your answer: No. Rainforests lie inside the territory of particular states, so they come under national sovereignty, however much the world depends on them. The four commons are the atmosphere, Antarctica, the ocean floor and outer space.

Common property is a different idea. A common property resource is owned and managed by a community, whose members share both rights and duties for its use and upkeep. The textbook's Indian example is the sacred grove of the south Indian forest belt, where villages have managed forest patches for centuries under religious sanction.

Feature Global commons Common property resources
Who controls it No state; humanity as a whole A community
Example Atmosphere, Antarctica Sacred grove
Scale Global Local

Common but differentiated responsibilities (CBDR)

The Rio Declaration of 1992 accepted a key principle: all states share responsibility for protecting the global environment, but developed countries bear a greater share because their industrial growth contributed most to the damage. The UNFCCC of 1992 asked countries to act on the basis of equity and in line with their common but differentiated responsibilities and respective capabilities.

On this logic, the Kyoto Protocol (agreed at Kyoto, Japan, in 1997) set greenhouse gas reduction targets only for industrialised countries. China, India and other developing countries were exempt from binding targets. The gases covered include carbon dioxide, methane and hydrofluorocarbons.

Two views. For the exam: developing countries argue that developed countries are historically responsible for most emissions and should do more. India, for example, points to its low per capita emissions. Another reading: some developed countries argue that as major developing economies grow, their emissions rise quickly and they too should accept limits. This disagreement is at the heart of climate negotiations.

India's stand

Point Detail
Kyoto Protocol Signed and ratified in August 2002
Paris Climate Agreement Ratified on 2 October 2016
Per capita carbon dioxide emissions Predicted to rise from 0.9 tonnes in 2000 to 1.6 tonnes by 2030, still less than half the 2000 world average of 3.8 tonnes
Renewable energy One of the world's largest programmes
Laws and policies National Auto-fuel Policy, Energy Conservation Act 2001, Electricity Act 2003 (encourages renewables)

India's position rests on historical responsibility: its emissions are low, and a limit on its per capita emissions would be unfair.

Pause and predict: If CBDR exempts India from binding targets under Kyoto, why did India still ratify the protocol?

Check your answer: The exemption applies to binding emission cuts, not to participation. By ratifying in August 2002, India joined the regime while keeping its argument that developed countries should lead.

Environmental movements

Not every environmental protest is about the same thing. These are the cases the chapter lists.

Type Examples
Forest movements Mexico, Chile, Malaysia, Indonesia, the Philippines, Brazil and India
Anti-mining Campaigns in the Philippines against the Western Mining Corporation
Anti-dam Narmada Bachao Andolan in India, rooted in non-violence; the Franklin River campaign in Australia in the early 1980s

Beyond the textbook. For the exam: the first anti-dam movement in the North was the early 1980s campaign to save Australia's Franklin River. In reality: the river is in Tasmania, and the proposed dam was stopped after a High Court of Australia ruling in 1983. The campaign is remembered as a landmark of the environmental movement in the North.

Resource geopolitics

Resource geopolitics asks who gets what, when, where and how. The chapter covers two resources.

Resource What the chapter says
Oil The single most important resource; West Asia (the Gulf) accounts for about 30 per cent of global production and 64 per cent of known reserves; Saudi Arabia holds a quarter of world reserves and Iraq comes second
Water Disputes usually involve downstream (lower riparian) states objecting to dams, diversion or pollution by upstream (upper riparian) states

Water examples: Israel, Syria and Jordan in the 1950s and 1960s over the Jordan and Yarmuk rivers, and Turkey, Syria and Iraq over the Euphrates.

Indigenous peoples and their rights

The UN defines indigenous populations as the descendants of peoples who inhabited a country's present territory when people of a different culture or ethnic origin arrived there. There are about 30 crore indigenous people worldwide. In India they are identified with the Scheduled Tribes, about 8 per cent of the population.

Their traditional way of life depends on subsistence agriculture, hunting, gathering and fishing, in close contact with forests and water. They have suffered most from the conversion of common land into private property, from mining and dam projects, and from displacement. Their demands are recognition as distinct peoples, secure land rights, protection of customary self-government and a say in global environmental talks. The World Council of Indigenous Peoples was formed in 1975 and was the first of 11 indigenous NGOs to get consultative status at the UN.

The big idea: environment and justice

All these threads lead to one idea: environmental questions cannot be separated from fairness between countries and within them. The Rio model combines sustainable development, CBDR and respect for common property. India's position combines participation in the global regime (Kyoto in 2002, Paris in 2016), insistence on historical responsibility, and domestic laws such as the Energy Conservation Act 2001 and the Electricity Act 2003.

Exam traps

The trap Why it's tempting The truth
"The Earth Summit was in Stockholm or Johannesburg." Both hosted environmental conferences The Earth Summit was at Rio de Janeiro, June 1992
"The Brundtland Report came after Rio." Rio feels like the starting point It came in 1987, five years earlier
"Kyoto was agreed at Rio." Both deal with climate Kyoto Protocol: 1997, Kyoto, Japan; India ratified in August 2002
"Forests are global commons." Forests matter to everyone The commons are the atmosphere, Antarctica, ocean floor and outer space
"CBDR means developing countries have no duty." They were exempt from Kyoto targets All states share responsibility; developed countries bear more
"Narmada was the first anti-dam movement in the North." Both are well known Narmada is Indian; the first in the North was the Franklin River in Australia
"Common property and global commons are the same." Both involve shared resources Common property is community managed; the commons are outside state sovereignty
"Gulf oil is 64 per cent of production." The two numbers look alike About 30 per cent of production and 64 per cent of known reserves
