CBSE Class 12 Political Science Chapter 8: Environment and Natural Resources NCERT Solutions

Solution: The most accurate explanation for the growing global concerns about the environment is that environmental degradation, largely caused by human activities, has become widespread and has reached a critical, dangerous level. While protecting nature and indigenous people are important aspects, the pervasive nature of the damage is the primary driver of concern.

Answer: (c) The environmental degradation caused by human activities has become pervasive and has reached a dangerous level.

Solution: Let's evaluate each statement regarding the Earth Summit (Rio Summit 1992):

(a) Correct: The summit saw participation from approximately 170 countries, along with numerous NGOs and representatives from multinational corporations.

(b) Wrong: While the UN played a crucial role in organizing and supporting the summit, it was not held strictly 'under the aegis' of the UN in the sense of being a UN General Assembly session. It was a conference convened by the UN.

(c) Correct: The Earth Summit was a landmark event where global environmental issues were brought to the forefront and firmly integrated into the international political agenda.

(d) Wrong: While it was a high-level meeting, calling it simply a 'summit meeting' might be an understatement. It was a comprehensive conference focused on environment and development.

Answer: (a) Correct, (b) Wrong, (c) Correct, (d) Wrong

Solution: Let's analyze the statements concerning Global Commons:

(a) True: These areas are indeed considered Global Commons as they lie beyond the territorial boundaries and sovereign control of any single nation.

(b) True: A defining characteristic of Global Commons is that they are not subject to the exclusive sovereignty of any one state.

(c) True: The management and exploitation of Global Commons often highlight the differing interests and priorities between developed (North) and developing (South) countries, reflecting the North-South divide.

(d) False: While both North and South have concerns, the nature and priority of these concerns can differ. Often, the South is more concerned about equitable access and development, while the North might focus more on conservation and regulation, leading to differing levels of concern about specific aspects of protection.

Answer: (a), (b), and (c) are true.

Solution: The Rio Summit, also known as the Earth Summit held in 1992, had several significant outcomes:

1. International Conventions: It produced key international agreements, including conventions aimed at addressing climate change (UNFCCC) and preserving biodiversity (CBD). It also addressed issues related to forestry.
2. Agenda 21: A comprehensive action plan was recommended, known as Agenda 21, which outlined a blueprint for sustainable development practices globally.
3. Sustainable Development: The summit strongly promoted the concept of sustainable development, emphasizing the need to combine economic growth with ecological responsibility and social equity.
4. Highlighting Global Commons: The summit brought issues related to Global Commons and their management to the forefront of international environmental politics, acknowledging the complexities and the North-South divide.

Solution:

Meaning of Global Commons: Global Commons are those regions or areas that lie outside the sovereign jurisdiction of any one state. They are considered the common heritage of humankind and require collective governance by the international community. Key examples include the Earth's atmosphere, the oceans beyond national jurisdiction (the high seas), the ocean floor, and outer space.

Exploitation and Pollution of Global Commons: These areas are vulnerable to exploitation and pollution due to several factors:

1. Lack of Consensus and Vague Evidence: Sometimes, there is a lack of clear scientific evidence or a consensus among nations regarding the extent of environmental damage or the specific causes, making it difficult to implement effective regulations.
2. North-South Inequalities: The differing economic interests and priorities between developed (North) and developing (South) countries lead to conflicts. Developing countries may prioritize economic development, sometimes at the expense of environmental protection, while developed countries may push for stricter regulations. This competition and differing approaches contribute to exploitation.
3. Technological and Industrial Development: Advancements in technology and industrial activities, particularly by developed nations, have significantly impacted the global commons. For instance, industrial emissions affect the atmosphere, and shipping and resource extraction impact the oceans and ocean floor.
4. Inadequate Management and Regulation: The very nature of Global Commons, being outside national control, makes effective management and enforcement of regulations challenging. This can lead to a 'tragedy of the commons' scenario where individual actors exploit resources without considering the collective long-term consequences.

Solution:

Meaning of 'Common but Differentiated Responsibilities' (CBDR): The principle of 'Common but Differentiated Responsibilities' (CBDR) is a cornerstone of international environmental law. It acknowledges that while all states share a common responsibility to conserve, protect, and restore the health and integrity of the Earth's ecosystem, they do not have the same level of responsibility or capacity to do so. This differentiation is based on factors such as historical contributions to environmental degradation and the availability of technological and financial resources. Developed countries, having contributed more significantly to global environmental problems and possessing greater resources, are expected to take a leading role in addressing them.

Implementation of the Idea: The concept of CBDR can be implemented through various international agreements and cooperative mechanisms:

1. International Conventions and Agreements: Treaties like the UN Framework Convention on Climate Change (UNFCCC) and its subsequent protocols (e.g., the Kyoto Protocol) explicitly incorporate the principle of CBDR. These agreements set different targets and obligations for developed and developing countries regarding emission reductions and climate action.
2. Financial and Technological Assistance: Developed countries can fulfill their differentiated responsibilities by providing financial aid and transferring environmentally sound technologies to developing countries. This helps developing nations pursue sustainable development pathways without compromising their economic growth.
3. Capacity Building: Supporting developing countries in building their institutional and technical capacities to manage environmental resources and implement environmental policies is another way to implement CBDR.
4. Rio Summit and Agenda 21: The Rio Summit itself, through Agenda 21, emphasized the need for cooperation and differentiated approaches, recognizing the varying capacities and contributions of nations to global environmental challenges.

Solution: Issues related to global environmental protection have escalated to become a priority concern for states since the 1990s due to a confluence of factors:

1. Increased Awareness and Scientific Evidence: Growing scientific understanding and evidence highlighted the severity and interconnectedness of environmental problems like climate change, ozone depletion, and biodiversity loss, demonstrating their potential to impact all nations.
2. Landmark International Conferences: The United Nations Conference on Environment and Development (UNCED), famously known as the Rio Summit or Earth Summit in 1992, was a pivotal event. It brought environmental issues to the highest political levels, consolidating global environmental concerns and leading to significant agreements like Agenda 21, the Convention on Biological Diversity, and the UN Framework Convention on Climate Change (UNFCCC).
3. Recognition of Interdependence: States realized that environmental problems transcend national borders and require collective action. Pollution in one country can affect others, and global issues like climate change demand international cooperation for effective solutions.
4. Emergence of Sustainable Development as a Goal: The concept of sustainable development, popularized by the Rio Summit, provided a framework for integrating economic development with environmental protection, making it a more palatable and prioritized issue for governments.
5. International Agreements and Protocols: Subsequent international agreements, such as the Kyoto Protocol (which set targets for greenhouse gas emission reductions), further solidified environmental protection as a key area of international policy and state concern.

These developments collectively elevated environmental protection from a niche concern to a central issue in international relations and national policy-making.
