Why Switzerland Needs a Healthy Ocean: Global Interdependence and National Responsibility

The ocean is a shared global commons that benefits all humanity, regardless where we live. Although landlocked, Switzerland is closely connected to the ocean through critical ecosystem services. Covering 71% of the Earth’s surface, the ocean regulates the global climate, sustains essential biogeochemical cycles (including carbon, oxygen, and nutrients), and supports biodiversity that underpins food security, medicine, and biotechnology. It also provides renewable energy, critical raw materials, and irreplaceable cultural, educational, and scientific value. All these benefits depend on a healthy and well-governed marine environment. 

Switzerland has a critical role to play in advancing global ocean stewardship. This summary outlines key ocean-related services relevant to Switzerland and underscores why ocean health must be a national concern. Yet significant knowledge gaps remain in quantifying Switzerland’s dependence on the ocean, highlighting the need for a precautionary approach in policy and decision-making.
