Thousands of economists have spent years or decades studying the interaction between climate change and the economic systems that underlie modern life. The views of these experts can help clarify how climate change will likely affect our society and economy, and how policymakers should approach greenhouse gas emission reduction efforts.

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.

The future of the global ocean economy is currently envisioned as advancing towards a ‘blue economy’—socially equitable, environmentally sustainable and economically viable ocean industries. However, tensions exist within sustainable development approaches, arising from differing perspectives framed around natural capital or social equity.

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.
