Conserve and sustainably use the oceans, seas and marine resources for sustainable development

Destructive trends in ocean health have not abated. The ocean, the world’s largest ecosystem, continues to be endangered by rising acidification, eutrophication, declining fish stocks and mounting plastic pollution. While there has been some progress in expanding marine protected areas and combatting illegal, unreported and unregulated fishing over the years, more concerted efforts and acceleration are urgently needed. Urgent and coordinated global action is needed to continue to advance towards SDG14.

Oceans, seas, and coastal areas form an integrated and essential component of the Earth’s ecosystem and are critical to sustainable development. They cover more than two-thirds of the earth’s surface and contain 97% of the planet’s water. Oceans contribute to poverty eradication by creating sustainable livelihoods and decent work. Over three billion people depend on marine and coastal resources for their livelihoods. In addition, oceans are crucial for global food security and human health. They are also the primary regulator of the global climate, an important sink for greenhouse gases and they provide us with water and the oxygen we breathe. Finally, oceans host huge reservoirs of biodiversity.

In order for oceans, seas and marine resources to successfully contribute to human well-being, ecosystem integrity, with properly functioning biogeochemical and physical processes, is required. This does not require unperturbed systems, but systems that have not suffered serious or irreversible harm. Ecosystem integrity allows for the provision of so-called supporting ecosystem services which, in turn, are the bases of important regulating, provisioning, and cultural ecosystem services that are of crucial importance for humans.

Good governance, an enabling environment, sustainable land- and marine- based human activities, and adequate measures will be required to reduce the negative anthropogenic impacts on the marine environment, for example due to a more sustainable use of resources, changes in production and consumption patterns and improved management and control of human activities. Projects and measures should ideally be designed and implemented in an integrated, cross-sectoral and cross-scale manner, in line with the ecosystem approach and involving all stakeholders.
