IUU fishing activity has the potential to ‘evolve significantly’ with ocean warming

A new report is warning that ocean warming caused by climate change could intensify IUU fishing and threaten global security.

A new report is warning that ocean warming caused by climate change has the potential to intensify illegal, unreported and unregulated fishing (IUU) fishing and threaten global security.

The report, which was released by the leading defense and security think tank Royal United Services Institute (RUSI), offers a comprehensive global horizon scan that explores the impacts of climate change on IUU fishing over the next decade and beyond. The report concludes that there is potential for IUU fishing activity to “evolve significantly” in a warming world, with current patterns of operation already shifting as a result of climate change.

“Climate change has the potential to gradually alter interactions between humans and the aquatic environment,” wrote the report’s authors. “Fish is a key source of protein in human diets and shifts in sea temperature, salinity, weather systems and sea level have the potential to alter not only current patterns of distribution but also human patterns of (legal and illegal) fishing, processing and consumption.”

As fish populations and distributions shift in a warming climate, IUU fishing actors may be forced to adapt, altering their way of working. Moreover, where livelihoods and food security are affected by climate change, fishers engaging in legitimate practices may be driven into IUU activity.

The effects of climate change on fish stocks could affect yields and fishing-dependent livelihoods while rising temperatures and sea levels could affect human migration to and from coastal areas, the viability of fisheries infrastructure and the nature of IUU fishing dynamics.

At the same time, global seafood consumption is predicted to continue to grow, having risen at more than twice the rate of population growth since the 1960s.

The report also highlights that climate change could “challenge existing governance frameworks, cooperative mechanisms and enforcement models, as well as presenting potential opportunities for national and global efforts to combat IUU fishing.”

“The need to anticipate these issues is pressing,” wrote the authors. “Globally, the impact of climate change on aquatic species is already being felt. Some species, depending on their mobility and habitat connection, are responding by shifting their distributions poleward and to deeper waters. Although some species are predicted to respond positively, there are indications that future changes in water temperatures could have a negative impact on many aquatic species.”
