United NationsThe Second World Ocean Assessment (WOA II) is the major output of the second cycle of the Regular Process for Global Reporting and Assessment of the States of the Marine Environment, including Socioeconomic Aspects. It is the newest outcome of the only integrated assessment of the world’s ocean at the global level covering environmental, economic and social aspects.

Seaweed aquaculture is capable of removing large quantities of nitrogen and phosphorus from coastal ecosystems, yet seaweed has gained little traction for its potential role in targeted nutrient assimilation.

NRDC conducted a detailed review, including geospatial analysis and mapping, of how each of the eight federal regional management councils (councils) have implemented the Magnuson-Stevens Act’s requirement to designate and minimize harms from fishing to “essential fish habitat” or EFH.

The sustainability of aquaculture has been debated intensely since 2000, when a review on the net contribution of aquaculture to world fish supplies was published in Nature. This paper reviews the developments in global aquaculture from 1997 to 2017, incorporating all industry sub-sectors and highlighting the integration of aquaculture in the global food system.

Disruptive changes in our global ocean and fisheries have sparked warnings of an increase in fishery conflicts. However, such environmental changes have not yet been considered in tandem with other critical social, economic, and political trends for mapping out possible future trajectories for fishery conflict.

Roque, BM et al., PLoS ONELivestock production, particularly ruminants, contributes to anthropogenic greenhouse gas (GHG) emissions globally. These emissions are estimated to be 7.1 Gt carbon dioxide (CO2) equivalents annually which accounts for approximately 14.5% of the global anthropogenic GHG emissions. The majority of GHG emissions from livestock production is in the form of methane (CH4), which is produced largely through enteric fermentation and to a lesser extent manure decomposition.

In this report, using an entire industry of a G7 country as a case study, Planet Tracker shows how the depletion of the natural world negatively impacts financials, and how improved sustainability could drive better financial performance. Analysts and portfolio managers must therefore understand and account for natural capital and its interplay with financial performance.

Stanford Center for Ocean Solutions (COS) and the Stanford Law School (SLS)Illegal, unreported and unregulated (IUU) fishing is a complex, systemic issue with impacts that resonate through global supply chains and can particularly harm those most vulnerable: the workers on fishing vessels. The millions of tons of fish stolen each year result in a huge loss to the economies of coastal nations and a threat to food security for the billion people who depend on fish for protein. Additionally, vessels that fish illegally often engage in labor abuses, including everything from substandard working conditions to modern slavery, prompting a human rights crisis.

Seasonal or chronic nutrient limitations in the photic zone limit large-scale cultivation of seaweed (macroalgae) in much of the world's oceans, hindering the development of macroalgae as a biofuel feedstock. One possible solution is to supply nutrients using a diel depth-cycling approach, physically moving the macroalgae between deep nutrient-rich water at night and shallow depths within the photic zone during the day.

This brief sets out the contribution that aquaculture can make to healthy diets and resilient food systems. It provides guidance for policymakers as they consider decisions related to the expansion of aquaculture, balancing issues related to diets and food security, economic growth and employment, and the environment.

Since the industrial revolution, the world’s oceans have become increasingly acidic. The main drivers of ocean acidification in Massachusetts are (1) global increases in atmospheric carbon dioxide resulting from anthropogenic emissions, and (2) local nutrient pollution leading to the eutrophication of coastal waters.

Anna Sanchez-Vidal et al., Scientific Reports, NatureThere is strong evidence that the seafloor constitutes a final sink for plastics from land sources. There is also evidence that part of the plastics lying on the shallow seafloor are washed up back to the shoreline. However, little is known on the natural trapping processes leading to such landwards return.
