CBSE Class 12 Political Science - Environment and Natural Resources NCERT Solutions

Global commons refer to areas or resources that lie outside the national jurisdiction of any country and are considered the common heritage of all humankind. These are not owned by any particular state but are available for use by all, creating shared responsibilities for their protection and management.

Examples of global commons include:

• The high oceans and seabeds beyond national jurisdiction
• The atmosphere and outer space
• Antarctica
• The Arctic region (to some extent)

The issue of global commons has gained prominence in world politics for several reasons:

• They are essential for planetary survival and ecological balance
• They face threats from overexploitation and environmental degradation
• No single nation can protect or manage them effectively alone
• Their management requires international cooperation and governance
• Their benefits and burdens affect all nations, creating shared interests and responsibilities
• They are subject to competing territorial claims and resource extraction
• They are increasingly linked to global security concerns and climate stability

The "tragedy of the commons," a concept introduced by ecologist Garrett Hardin in 1968, describes a situation where individuals, acting independently and rationally according to their self-interest, behave contrary to the best interests of the whole group by depleting or spoiling a shared resource.

In the context of global environmental problems:

• It explains why resources like the atmosphere, oceans, and forests get degraded despite everyone understanding the long-term consequences
• Individual nations or actors maximize their short-term benefits from these commons while the costs of degradation are shared by all
• It creates a classic collective action problem where rational individual decisions lead to collectively irrational outcomes
• The solution typically requires either formal regulations or informal agreements to restrict access and use

Sustainable development, which meets present needs without compromising the ability of future generations to meet their own needs, faces several challenges:

• Economic constraints: Developing countries prioritize immediate economic growth over long-term sustainability
• Competing interests: Nations have different priorities based on their development levels and resource endowments
• Implementation gaps: International agreements often face challenges in national implementation
• Technological limitations: Sustainable technologies may not always be available or affordable
• Funding shortages: Developing nations lack sufficient resources for sustainable development projects
• Political will: Short electoral cycles discourage long-term environmental planning
• Consumer culture: Rising consumption patterns in developed and developing nations strain resources
• Inequitable burden sharing: Disagreements over who should bear the costs of environmental protection

The "North-South divide" in environmental politics refers to the differing perspectives, responsibilities, and priorities of developed countries (North) and developing countries (South) on environmental issues:

• Historical responsibility: The North acknowledges greater historical responsibility for environmental degradation while the South emphasizes current development needs
• Emission rights: The South advocates for per capita emission rights, while the North focuses on total emissions
• Technology transfer: The South seeks technology transfer and financial support for sustainable development
• Development priorities: The South prioritizes poverty alleviation and development over environmental conservation
• Implementation burden: Disagreements on who should bear the costs of implementing environmental agreements
• Commitment levels: The North wants binding commitments from all countries, while the South wants differentiated responsibilities

The Rio Earth Summit (United Nations Conference on Environment and Development) held in 1992 was a milestone in global environmental governance with several significant outcomes:

• It elevated environmental issues to the highest political level with participation from 172 countries, including 108 heads of state
• It produced five key documents: Rio Declaration, Agenda 21, Convention on Biological Diversity, Forest Principles, and Framework Convention on Climate Change
• It established the principle of "Common but Differentiated Responsibilities" (CBDR), recognizing different capacities and responsibilities of developed and developing nations
• It popularized the concept of sustainable development as a framework for balancing development and environmental protection
• It formalized processes for international environmental cooperation and negotiations
• It led to the establishment of the Commission on Sustainable Development to monitor implementation
• It empowered civil society by providing platforms for NGOs and other stakeholders in environmental decision-making

Non-state actors play increasingly important roles in global environmental politics:

• Environmental NGOs: Organizations like Greenpeace, WWF, and Friends of the Earth advocate for environmental protection, raise public awareness, and sometimes directly monitor compliance with environmental agreements
• Scientific community: Provides crucial data and assessments through bodies like the Intergovernmental Panel on Climate Change (IPCC) that shape policy discussions
• Business corporations: Multinational corporations influence environmental outcomes through their practices and technological innovations, though their motives may vary
• Social movements: Grassroots movements and indigenous groups advocate for environmental justice and protection of local ecosystems
• Transnational advocacy networks: Connect diverse actors across borders to share information and coordinate campaigns
• Think tanks and academic institutions: Contribute research, policy analysis, and new ideas for addressing environmental challenges
• UN and international organizations: While comprising member states, these bodies often develop semi-independent initiatives and programs

The ecological footprint is a measure of human demand on Earth's ecosystems. It represents the amount of biologically productive land and sea area necessary to supply the resources a human population consumes and to assimilate the associated waste.

Key aspects of the ecological footprint include:

• It measures both resource consumption and waste generation
• It expresses demand in terms of global hectares (standardized units with average productivity)
• It can be calculated for individuals, cities, regions, countries, or the entire human population
• When humanity's ecological footprint exceeds Earth's biocapacity, it indicates ecological overshoot
• Currently, the global ecological footprint exceeds Earth's biocapacity by approximately 1.7 times, meaning humanity uses resources equivalent to 1.7 Earths annually
• Developed countries typically have much larger per capita ecological footprints than developing countries
• The concept helps visualize sustainability challenges and track progress toward sustainable use of resources

Several major global environmental agreements have been established:

• UN Framework Convention on Climate Change (1992): Established international cooperation on climate change issues
• Kyoto Protocol (1997): Set binding emission reduction targets for developed countries
• Paris Agreement (2015): Established global framework for limiting global temperature increase
• Convention on Biological Diversity (1992): Aims at conservation of biological diversity and sustainable use of its components
• Vienna Convention and Montreal Protocol (1985 & 1987): Addressed depletion of the ozone layer
• Convention on International Trade in Endangered Species (1973): Regulates cross-border trade in threatened species
• UN Convention to Combat Desertification (1994): Addresses problems of land degradation in drylands
• Stockholm Convention on Persistent Organic Pollutants (2001): Aims to eliminate or restrict production and use of persistent organic pollutants

The Chipko Movement was a significant environmental movement in India during the 1970s with lasting impacts:

• It originated in the Himalayan region of Uttarakhand (then part of Uttar Pradesh) where villagers hugged trees to prevent them from being felled by contractors
• It highlighted the connection between environmental protection and people's livelihoods, especially those dependent on forests for survival
• The movement successfully prevented deforestation in several areas and forced policy changes in forest management
• It demonstrated the power of nonviolent protest and influenced environmental movements worldwide
• The movement emphasized that environmental conservation cannot be separated from social justice and local community rights
• It created awareness about the ecological importance of forests in preventing soil erosion, maintaining water cycles, and supporting biodiversity
• It influenced environmental thinking and policies, contributing to the recognition of forest rights and the need for community-based forest management
• The name "Chipko" (meaning "to embrace") became symbolic of environmental resistance movements globally
