Navigating the Future V: Marine Science for a Sustainable Future

Abstract

Navigating the Future is a publication series produced by the European Marine Board providing future perspectives on marine science and technology in Europe. Navigating the Future V (NFV) highlights new knowledge obtained since Navigating the Future IV (2013). It is set within the framework of the 2015 Paris Agreement and builds on the scientific basis and recommendations of the IPCC reports. NFV gives recommendations on the science required during the next decade to deliver the ocean we need to support a sustainable future. This will be important for the United Nations Decade of Ocean Science for Sustainable Development (2021 – 2030), the implementation of the UN Sustainable Development Goals and the European Commission’s next framework programme, Horizon Europe (2021 - 2027). There is a growing need to strengthen the links between marine science, society and policy since we cannot properly manage what we do not know. In recent years, the ocean and seas have received new prominence in international agendas. To secure a safe planet a priority is the management of the ocean as a “common good for humanity”, which requires smarter observations to assess of the state of the ocean and predictions about how it may change in the future. The ocean is a three-dimensional space that needs to be managed over time (thus four-dimensional), and there is a need for management and conservation practices that integrate the structure and function of marine ecosystems in these four dimensions. This includes understanding the dynamic spatial and temporal interplay between ocean physics, chemistry and biology. Multiple stressors including climate change, pollution and over-fishing affect the ocean and we need to better understand and predict their interactions and identify tipping points to decide on management priorities. This should integrate our understanding of land-ocean-atmosphere processes and approaches to reducing impacts. An improved science base is also needed to help predict and minimize the impact of extreme events such as storm surges, heat waves, dynamic sea-floor processes and tsunamis. New technologies, data handling and modelling approaches will help us to observe, understand and manage our use of the four-dimensional ocean and the effect of multiple stressors. Addressing these issues requires a strategic, collective and holistic approach and we need to build a community of sustainability scientists that are able to provide evidence-based support to policy makers within the context of major societal challenges. We outline the new frontiers, gaps and recommendations needed to manage the ocean as a common good and to develop solutions for a sustainable future. The governance of sustainability should be at the core of the marine research agenda through co-production and collaboration with stakeholders to identify priorities. There is need for a fully integrated scientific assessment of resilience strategies, associated trade-offs and underlying ethical concepts for the ocean, which should be incorporated into decision support frameworks that involve stakeholders from the outset. To accurately assess the state of the ocean and make predictions for the future, research programmes should be co-designed with stakeholders. Achieving the ocean we need for a sustainable future by 2030 will require sustainability science, which is holistic and transdisciplinary. To allow the collection, processing and access to all data, a key priority is the development of a business model that ensures the long-term economic sustainability of ocean observations.

A Blueprint for Ocean Literacy: EU4Ocean

“…The worldwide education system can be conventionally divided into formal, informal and non-formal education [5,19,26,27]. Formal education is primarily realized in all levels of schools, and as vocational training.…”

“…Additionally, the ocean provides numerous benefits to communities worldwide, from natural aspects, such as mitigating climate changes and threats to food resources, to more civilization-related ones, including employment, transportation as well as recreation and cultural features [4]. All of these benefits strongly depend on the state of the ocean environment, biodiversity and related ecosystem services, and it is clear that the main threats to marine ecosystems come from a number of human activities, including pollution and the release of greenhouse gases [1- 3,5,6].…”

“…We now realize that, without firm and quick actions devoted to climate and ocean change processes, we will soon lose control over the environmental pressures and drivers (with very complex and often difficult-to-predict linkages) and thus processes which govern the climate [1- 3,6]. These actions require changes in lifestyles, including the rate of the global production of goods and thus the consumption levels, that directly apply pressures to the entire planet [5].…”

The perspectives of first-year students on interprofessional education as a vehicle for achieving Sustainable Development Goal 3

“…Within the agenda are the 17 Sustainable Development Goals (SDGs), which are to be implemented by the governments of developed and developing countries. [1] The SDGs build upon the Millennium Development Goals by emphasising the goals that have not yet been achieved. The 17 SDGs (Fig.…”
