Environment and Natural Resources

Global politics shifting from traditional wars to shared ecological survival, resource management, and the political power dynamics of sustainability.

  1. Environmental Politics Overview

    Environmental issues became political in the 1960s, involving power struggles over resource damage and corrective action.

    • Limits to Growth — 1972 Club of Rome publication dramatized resource depletion against rapid population growth.
    • Human Survival Crisis — 663 million in developing nations lack safe water; loss of fertility and overharvesting affect food production.
  2. The 1992 Rio Earth Summit

    The UN Conference on Environment and Development (UNCED) in Brazil marked a turning point in global policy.

    • North-South Divide — North focused on ozone and warming; South prioritized economic development and poverty alleviation.
    • Agenda 21 — A list of development practices for sustainability, though criticized for favoring economic growth.
  3. Protection of Global Commons

    Resources not owned by any single state but shared by the international community (res communis humanitatis).

    • Shared Domains — Includes the Earth's atmosphere, Antarctica, the ocean floor, and outer space.
    • International Treaties — 1959 Antarctic Treaty, 1987 Montreal Protocol, and 1991 Antarctic Environmental Protocol.
  4. Common but Differentiated Responsibilities

    Principle that developed nations bear a greater burden due to historical industrial emissions.

    • Historical Responsibility — Argument that Northern industrialization caused most damage; accepted in the 1992 Rio Declaration.
    • Kyoto Protocol (1997) — Set mandatory targets for industrialized nations; India and China were exempted due to low per capita emissions.
  5. India's Environmental Stand

    India prioritizes economic development while participating in global climate efforts like the Paris Agreement.

    • Domestic Initiatives — Energy Conservation Act (2001), Electricity Act (2003), and National Auto-fuel Policy.
    • Emission Projections — India's 2030 per capita carbon emissions (1.6 tonnes) will remain below the 2000 world average (3.8 tonnes).
  6. Global Environmental Movements

    Grassroots actions focusing on local issues like forest conservation and opposition to mining.

    • North vs South Perspectives — North views forests as 'wilderness'; South assumes people live within and depend on forests.
    • Key Campaigns — Narmada Bachao Andolan (India), Franklin River (Australia), and Western Mining Corp (Philippines).
  7. Resource Geopolitics

    Strategic struggles over control of oil and water as drivers of international conflict.

    • Oil and the Gulf — The Gulf region holds 64% of known oil reserves; industrialized nations use military force to ensure flow.
    • Water Wars — Disputes between riparian states over the Jordan and Euphrates rivers regarding dams and pollution.
  8. Indigenous Peoples' Rights

    30 crore people worldwide whose survival is tied directly to ancestral land and resources.

    • Threat of Land Loss — Loss of land to dams and mines destroys their economic base; Scheduled Tribes in India face displacement.
    • Global Representation — World Council of Indigenous Peoples (1975) works to bring concerns to the global stage.

Chapter notes

An analysis of environmental issues and resource competition in global politics, covering the Earth Summit, global commons, the North-South divide in environmental responsibility, and the rights of indigenous peoples.

Environmental Concerns in Global Politics

While traditional world politics focuses on wars and treaties, environmental issues have emerged as a critical political arena because they transcend national borders.

Environmental degradation is no longer just a geographical concern; it is deeply political. Issues such as the loss of agricultural fertility, overharvesting of fisheries, and the depletion of water bodies directly affect food production and human survival. According to the Human Development Report 2016, over 663 million people in developing countries lack access to safe water, leading to millions of child deaths annually.

Although environmental concerns have a long history, awareness of the consequences of economic growth acquired an increasingly political character from the 1960s onwards. A significant milestone was the 1972 publication of 'Limits to Growth' by the Club of Rome, a global think tank. The book dramatized the potential depletion of Earth's resources against the backdrop of a rapidly growing world population.

These problems are political because they involve questions of power: who causes the damage, who pays the price, and who is responsible for corrective action. Since no single government can solve global warming or ozone depletion alone, these issues require international cooperation and governance, making them a core part of contemporary world politics.

The 1992 Rio Earth Summit

The United Nations Conference on Environment and Development, held in Rio de Janeiro in 1992, marked a turning point in global environmental policy.

The Earth Summit was attended by 170 states, thousands of NGOs, and numerous multinational corporations. It was preceded by the 1987 Brundtland Report, 'Our Common Future', which warned that traditional economic growth was unsustainable. The summit highlighted a significant divide between the 'Global North' (developed countries) and the 'Global South' (developing countries).

While Northern states focused on ozone depletion and global warming, Southern states were more concerned with the relationship between economic development and environmental management. The summit resulted in conventions on climate change, biodiversity, and forestry, and produced 'Agenda 21', a list of development practices aimed at achieving sustainable development.

Protection of Global Commons

Global commons are resources not owned by any single state but shared by the international community.

The global commons include the Earth's atmosphere, Antarctica, the ocean floor, and outer space. These areas are known as 'res communis humanitatis'. Managing these resources is difficult because states often disagree on scientific evidence and time frames for action. For example, the discovery of the ozone hole over Antarctica in the mid-1980s highlighted the urgent need for cooperation.

Key international agreements have been established to protect these areas, such as the 1959 Antarctic Treaty, the 1987 Montreal Protocol, and the 1991 Antarctic Environmental Protocol. However, the management of these areas is often influenced by North-South inequalities, particularly regarding access to technology and the benefits of space exploration.

Key Agreements for Global Commons

  1. 1

    1959 Antarctic Treaty

    Limited activities in Antarctica to scientific research and peaceful purposes.

  2. 2

    1987 Montreal Protocol

    Addressed the depletion of the ozone layer by phasing out harmful substances.

  3. 3

    1991 Antarctic Environmental Protocol

    Provided further environmental protections for the Antarctic ecosystem.

Common but Differentiated Responsibilities

This principle acknowledges that while all states must protect the environment, developed nations bear a greater burden due to their historical emissions.

The Global South argues that most ecological degradation is the result of industrialization in the North. Therefore, developed countries should take more responsibility for undoing the damage. Furthermore, developing countries are still in the process of industrializing and should not be subjected to the same restrictive rules that might hamper their growth.

This argument was formally accepted in the 1992 Rio Declaration. It led to the 1997 Kyoto Protocol, which set mandatory targets for industrialized nations to reduce greenhouse gas emissions. Developing countries like India and China were exempted from these requirements because their per capita emissions were relatively low compared to the developed world.

India's Stand on Environmental Issues

India maintains that historical responsibility lies with developed nations while actively participating in global climate efforts.

India ratified the Kyoto Protocol in 2002 and the Paris Climate Agreement in 2016. India's position is based on the principle that 'economic and social development are the first and overriding priorities' for developing nations. Despite this, India has implemented significant domestic policies to improve energy efficiency and promote renewable energy.

Domestic initiatives include the Energy Conservation Act (2001), the Electricity Act (2003), and the National Auto-fuel Policy. The government is also keen to launch a National Mission on Biodiesel, using about 11 million hectares of land to produce biodiesel. India's per capita carbon emissions are predicted to rise from 0.9 tonnes in 2000 to 1.6 tonnes by 2030, which would still be less than half the world average of 3.8 tonnes recorded in the year 2000.

Global Environmental Movements

Significant environmental action often comes from grassroots movements rather than government policy.

Environmental movements are diverse and vibrant, often focusing on local issues like forest conservation or opposition to mining. In the Global South, forest movements often assume that people live within the forests, whereas in the North, forests are often viewed as 'wilderness' devoid of human habitat. This leads to different conservation strategies.

Examples of such movements include the campaign against the Western Mining Corporation in the Philippines and anti-dam movements. The early 1980s saw the first anti-dam movement launched in the North, namely the campaign to save the Franklin River and its surrounding forests in Australia. In India, the Narmada Bachao Andolan is one of the best-known movements, emphasizing non-violence and equitable resource management.

Resource Geopolitics: Oil and Water

The struggle for control over strategic resources like oil and water has been a major cause of international conflict.

Resource geopolitics is concerned with who gets what, when, where, and how. Historically, resources provided the means and motives for global power expansion. For example, since sea power rested on access to timber, naval timber supply became a key priority for major European powers from the 17th century onwards. In the 20th century, the focus shifted to petroleum.

West Asia, particularly the Gulf region, holds about 64% of the planet's known oil reserves, making it a focal point of global strategy and war. Industrialized nations have used military force, stockpiling, and support for friendly regimes to ensure a steady flow of petroleum.

Water is another critical resource that could lead to 'water wars' in the 21st century. Conflicts arise between upstream (upper riparian) and downstream (lower riparian) states over dam construction or pollution. Historical examples include disputes between Israel, Syria, and Jordan over the Jordan River, and tensions between Turkey, Syria, and Iraq over the Euphrates.

Indigenous Peoples and Their Rights

Indigenous populations face unique challenges as their survival is tied directly to the land and resources they have occupied for millennia.

The UN defines indigenous people as descendants of those who inhabited a territory before people of a different culture arrived and overcame them. There are approximately 30 crore indigenous people worldwide, including the Scheduled Tribes in India, who make up about 8% of the population. Their worldviews emphasize a deep connection to the land and its life systems.

The loss of land is the greatest threat to indigenous survival, as it destroys their economic base. In India, while they have constitutional protection for political representation, they have often been the group most displaced by developmental projects like dams and mines. The World Council of Indigenous Peoples, formed in 1975, works to bring these concerns to the global stage.
