• Bold new plans & innovations for vulnerable communities at the Ocean Conference

    The Ocean is in trouble. Some 60 per cent of the world’s major marine ecosystems have been degraded or are being used unsustainably. And when life underwater becomes more difficult, there are big implications for life on land. Billions of people depend on the Ocean for their main source of protein and millions of others draw their livelihood from the seas. Small Island Developed States (SIDS) are especially dependent on the ocean – but Least Developed Countries (LDCs) and even Landlocked Developing Countries (LLDCs) also depend on the ocean. That’s why this week’s Ocean Conference in Lisbon is such a big moment for the world’s most vulnerable states.

    The UN Office for the Most Vulnerable States (OHRLLS) will be at the Ocean Conference. Find out more.
