Does humanity's future lie in the ocean? As demand for resources continues to grow and land-based sources decline, expectations for the ocean as an engine of human development are increasing. Claiming marine resources and space is not new to humanity, but the extent, intensity, and diversity of today's aspirations are unprecedented. We describe this as the blue acceleration—a race among diverse and often competing interests for ocean food, material, and space. Exploring what this new reality means for the global ocean and how to steer it in a sustainable and equitable way represents an urgent challenge.

The Blue Acceleration: The Trajectory of Human Expansion into the Ocean

Marine Protected Areas (MPAs) are conservation tools intended to protect biodiversity, promote healthy and resilient marine ecosystems, and provide societal benefits. Despite codification of MPAs i...

The MPA Guide: A framework to achieve global goals for the ocean

The rapidly evolving ocean economy, driven by human needs for food, energy, transportation and recreation, has led to unprecedented pressures on the ocean that are further amplified by climate change, loss of biodiversity and pollution. The need for better governance of human activities in the ocean space has been widely recognized for years, and is now also incorporated in the United Nations Sustainable Development Goals. Even so, many challenges relating to the implementation of existing governance frameworks exist. Here, we argue that integrated ocean management (IOM) should be the key overarching approach—building upon and connecting existing sectoral governance efforts—for achieving a sustainable ocean economy. IOM is a holistic, ecosystem-based and knowledge-based approach that aims to ensure the sustainability and resilience of marine ecosystems while integrating and balancing different ocean uses to optimize the overall ocean economy. We discuss examples of IOM in practice from areas where preconditions differ substantially, and identify six universal opportunities for action that can help achieve a sustainable ocean economy. There is an urgent need to ensure that marine ecosystems are able to support biodiversity and the services they sustain in the face of rapid global change. Here, the authors argue that a holistic approach of integrated ocean management can ensure a sustainable and resilient ocean economy.

Bright Spots in Coastal Marine Ecosystem Restoration.

Frontiers in Marine Science launched the Marine EcosystemsEcology (FMARS-MEE) section in2014, with a paper that identified eight grand challenges for the discipline (Borja, 2014). Sincethen, this section has published a total of 370 papers, including 336 addressing aspects of thosechallenges. As editors of the journal, with a wide range of marine ecology expertise, we felt it wastimely to evaluate research advances related to those challenges; and to update the scope of thesection to reflect the grand challenges we envision for the next 10 years. This output will matchwith the United Nations (UN) Decade on Oceans Science for Sustainable Development (DOSSD;Claudet et al., 2020), UN Decade of Ecosystems Restoration (DER;Young and Schwartz, 2019), andthe UN Sustainable Development Goals (SDGs;Visbeck et al., 2014)

Past and Future Grand Challenges in Marine Ecosystem Ecology

The health of the ocean, central to human well-being, has now reached a critical point. Most fish stocks are overexploited, climate change and increased dissolved carbon dioxide are changing ocean chemistry and disrupting species throughout food webs, and the fundamental capacity of the ocean to regulate the climate has been altered. However, key technical, organizational, and conceptual scientific barriers have prevented the identification of policy levers for sustainability and transformative action. Here, we recommend key strategies to address these challenges, including (1) stronger integration of sciences and (2) ocean-observing systems, (3) improved science-policy interfaces, (4) new partnerships supported by (5) a new ocean-climate finance system, and (6) improved ocean literacy and education to modify social norms and behaviors. Adopting these strategies could help establish ocean science as a key foundation of broader sustainability transformations.
