FAQ
Ocean acidification is the result of increased levels of carbon dioxide in the atmosphere, which are absorbed by the world's oceans, leading to a decrease in seawater pH. This has transboundary consequences because it affects marine ecosystems and species worldwide. Acidic waters harm coral reefs, shellfish, and other marine life, disrupting the global food chain and fishing industries. Ocean acidification is a direct consequence of increased carbon emissions from multiple countries, making it a pressing transboundary environmental issue that necessitates international cooperation and emissions reduction.
The "polluter pays principle" is a fundamental concept in environmental governance that places the responsibility for environmental damage on those who cause it. It implies that the costs of preventing, managing, and mitigating environmental damage should be borne by the polluters rather than society at large. This principle is crucial in the context of transboundary environmental problems because it encourages accountability and incentivizes nations to reduce pollution and environmental harm. International agreements and treaties often incorporate variations of this principle to ensure that those responsible for transboundary pollution and degradation take action to address their impacts and contribute to environmental restoration efforts.
"Climate refugees" are individuals or communities who are forced to migrate due to the impacts of climate change, such as rising sea levels, extreme weather events, or droughts. Transboundary environmental problems, like climate change, play a significant role in creating climate refugees. As climate change affects entire regions, people are often compelled to leave their homes and seek refuge in other countries. This situation underscores the interconnectedness of global environmental challenges, as climate refugees cross borders, leading to political, social, and economic implications that require international cooperation to address.
Transboundary environmental problems are closely intertwined with the United Nations Sustainable Development Goals (SDGs), particularly Goal 13 (Climate Action) and Goal 14 (Life Below Water). Addressing these challenges contributes to the achievement of several SDGs. For instance, mitigating climate change (Goal 13) involves reducing greenhouse gas emissions, which is essential for sustainable development. Additionally, tackling ocean pollution (Goal 14) aligns with the preservation and sustainable use of marine resources, supporting life below water. Transboundary environmental issues often cut across multiple SDGs, highlighting the interconnectedness of global challenges and emphasizing the importance of international cooperation to meet the ambitious targets set by the United Nations.
The "Tragedy of the Commons" is a concept in environmental economics that relates to the overexploitation of shared resources. In the context of transboundary environmental problems, it refers to situations where multiple countries share a common resource, like a transboundary river or a shared ocean, and individual nations exploit it without considering the negative consequences for all. This leads to resource depletion and environmental degradation, highlighting the need for international cooperation and governance to prevent the tragedy from occurring.
Practice Questions
International agreements play a pivotal role in combating climate change by setting the framework for collective action and accountability. The Paris Agreement, for example, brings together nations under the common goal of limiting global warming to well below 2°C. This agreement marks a significant step as it recognises the differentiated responsibilities of developed and developing nations, emphasising the former's historical emissions. Its impact lies in fostering global solidarity, guiding national climate policies, and enabling regular updates of targets, reflecting the dynamic nature of climate science and geopolitical realities. However, its efficacy hinges on the genuine commitment and adherence of member states, and the fulfilment of financial and technological support promised to developing nations. This demonstrates how international agreements, while crucial, must be underpinned by national determination and international collaboration to be truly effective.
