Frida Bengtsson - Board Member

Frida Bengtsson is currently pursuing a PhD at the Stockholm Resilience Centre at Stockholm University where she works on ocean governance and the role of corporate stewardship in the management of marine resources.


She focuses in particular on ownership dynamics and governance systems that facilitate transshipments, a practice often described as opaque and underpinning illegal, unreported and unregulated (IUU) fishing as well as human rights abuses at sea. She is also involved in SeaBOS, a science-based collaboration between nine of the world’s largest seafood companies and scientific institutions to achieve sustainable transformations within the seafood sector.


Frida holds a Bachelor’s degree in social sciences with a major in Geography and a Master’s degree in Development Studies. 

Before joining the Stockholm Resilience Centre, she worked with Greenpeace where she was involved in and negotiated several sustainability commitments covering entire supply chains from Russian and Norwegian fishermen to household brands such as McDonalds and Birds Eye.


In 2018 she negotiated a major voluntary conservation agreement with the Association of Responsible Krill Harvesters (ARK) to limit fishing in key areas for penguins during the breeding season and to close an area in Antarctica for fishing all year around. She has also led multiple ship expeditions to Antarctica and to the Arctic.
