Impacts from climate change and ocean acidification on Fisheries and Marine biodiversity (IFMA) - ME5216


According to the 2008 UK Climate Change Act the government is required to conduct a Climate Change Risk Assessment (CCRA) every five years, and shortly after that, to put in place a National Adaptation Programme (NAP) that addresses the most pressing threats or enables the UK to mitigate against any threats and capitalise on any opportunities. The first UK CCRA was published in January 2012 and in response to this report, the first National Adaptation Programme was published in July 2013.

The NAP contains 20 different actions/commitments relating to the marine environment. This includes important actions attributed to Defra, Cefas or the Marine Climate Change Impacts Partnership (MCCIP) the secretariat for which is hosted at Cefas and chaired by Defra. These actions cut across a number of the NAP themes, including the natural environment, human health, biodiversity and fisheries. IFMA will help to address a number of these actions.


The IFMA project will consider a range of issues related to:

1) Changes in ocean chemistry, covering ocean acidification and low oxygen impacts on marine fish, invertebrates and ecosystems, as well as the relationship between acidification and metal toxicity.

2) Impacts on human health, covering the risks in the marine environment presented by vibrio pathogens and harmful algal blooms (HABs).

3) Impacts on biodiversity and fisheries, covering local scale economic losses of changing seabird distributions, as well as links between climate change, plankton and mackerel.

4) Emerging threats to the UK from Jellyfish outbreaks associated with present and future climate change.

The project will allow Cefas to start considering impacts in some of these areas (e.g. HABs), and in other cases it will allow Cefas staff to publish or build upon work that is already more developed (e.g. Vibrio pathogens).
