The ocean economy spans across multiple sectors – including fishing, aquaculture, tourism, transport and extractives – and is valued at USD 1.5 trillion. Yet, marine and coastal ecosystems also provide invaluable – and in most cases under-recognised– services, such as climate regulation, pollution control, storm protection, shoreline stabilisation, and habitats for species, all of which are under severe pressure from economic activities. In addressing the economic recovery from the COVID-19 crisis, governments need to discourage practices that could further undermine the sustainability of the ocean economy, such as overfishing, uncontrolled development of coastal zones, and pollution. This session focused on best practices, opportunities, and challenges for the greening of the ocean economy. The session discussed the role of an integrated approach to ocean management, such as Integrated Coastal Zone Management or Marine Spatial Planning, to ensure that multiple uses of the ocean are well aligned with the SDGs. How can marine protected areas ensure the sustainable use of marine resources? The debate also discussed the distributional impact of necessary policy reforms, how these could be addressed, and the role of new technologies for sustainable ocean use in the context of the upcoming UN Decade of Ocean Science for Sustainable Development (2021-2030).
