Impacts of climate change on marine fisheries, aquaculture, coastal tourism, and human health: an update

The Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), released in 2013 and 2014, highlighted the vulnerability, impacts and adaptation of marine systems to climate change and ocean acidification. As this field of research is constantly building and evolving, “Observed and projected impacts of climate change on marine fisheries, aquaculture, coastal tourism, and human health: an update” was recently published as an update of findings since the release of the report.

Where do we go from here? Building confidence in climate change impact projection models

Climate change is expected to have major impacts on the ocean, the species that live there, and the people who rely it for their food and livelihood. Since the beginning of the 20th century, CO2 emissions from human activities have altered physical and chemical properties of the ocean. The ocean has become warmer and, in some areas, less oxygenated, which has caused changes in the productivity and distribution of marine species.

Climate change effects on illegal, unreported and unregulated fishing

A range of human pressures is threatening the sustainability of marine fisheries. Amongst those, overfishing, partly driven by Illegal, Unreported and Unregulated (IUU) fishing, is a major stressor. Thirty percent of global fish catch goes unreported, found a recent study by Nereus Program collaborator Sea Around Us.

But the relationship between IUU fishing and climate change is a new topic. I speculate that climate change impacts on fisheries may indirectly increase IUU fishing.
