SDG 14: Life Below Water — Global Achievements, Challenges, and Pakistan’s Progress in Marine Conservation
Introduction
Sustainable Development Goal 14 (SDG 14), “Life Below Water,” emphasizes the conservation and sustainable use of the oceans, seas, and marine resources. Oceans cover more than 70% of the Earth’s surface and are central to life on the planet. They regulate climate, produce oxygen, and provide livelihoods for over 3 billion people. Yet, the health of the world’s oceans is under grave threat from pollution, overfishing, and climate change. SDG 14 calls for urgent action to restore ocean health and ensure its sustainable management for future generations.
Key Points of SDG 14
-
Reduce Marine Pollution:
Aim to reduce marine pollution by 2025, especially from land-based activities such as plastic and nutrient pollution. Plastic waste makes up nearly 80% of all marine pollution. Between 1 to 8 million tonnes of plastic enter the oceans annually. -
End Overfishing and IUU Fishing:
Combat illegal, unreported, and unregulated fishing (IUU) and promote science-based fishery management. Nearly 40% of global illegal fishing occurs off the coast of West Africa, often by foreign fleets. -
Expand Marine Protected Areas (MPAs):
Currently, about 8% of the world’s oceans are under some form of protection, while only 2.9% are considered “highly protected.” The 30×30 Initiative aims to protect 30% of land and oceans by 2030. -
Address Ocean Acidification:
Ocean pH has dropped from 8.11 in 1985 to 8.05 in 2021, harming coral reefs and shell-forming organisms. thereby disrupting marine ecosystems and fisheries. -
Promote Sustainable Blue Economy:
Encourage sustainable fisheries, aquaculture, and coastal tourism. The key economic sectors for Small Island Developing States (SIDS) are those in which tourism contributes up to 30% of the GDP. -
Enhance Marine Technology Transfer:
Under the BBNJ Treaty (Biodiversity Beyond National Jurisdiction), nations are encouraged to share marine data, technology, and expertise. -
Strengthen Legal Frameworks (UNCLOS):
The United Nations Convention on the Law of the Sea (UNCLOS) provides a global legal foundation for ocean governance. ensuring peaceful maritime use, environmental protection, and equitable resource sharing.
Global Achievements in SDG 14
