Fisheries, food security, climate change, and biodiversity: characteristics of the sector and perspectives on emerging issues

Fisheries, food security, climate change, and biodiversity: characteristics of the sector and perspectives on emerging issues. – ICES Journal of Marine Science, 68: 13431353.This paper reviews global projections to 2050 for human population growth and food production, both assuming constant climate and taking account of climate-related changes in growing conditions.

To meet projected food requirements, the production of fish has to increase by ∼50% from current levels.

It highlights that most of the actions being proposed to address pressures on marine biodiversity are totally incompatible with the actions considered necessary to meet future food security needs, particularly in less developed parts of the world.
