About me

My PhD project will be focusing on assessing parts of the methodology used in measuring sustainability of produce, more specifically in aquaculture.

Aquaculture shows great promise in supplying a growing global population with healthy food. However, many environmental issues are associated with aquaculture. The use of antibiotics in aquatic animal rearing schemes has been a growing concern due to the risks of accelerating the antimicrobial resistance development rate in human pathogenic bacteria, a rising problem to modern human healthcare.

Life cycle assessment (LCA; ISO 14040) is commonly used as a method for modelling the environmental effects of product chains, and the use to benchmark aquaculture operations using LCA is becoming more common. The LCA method will be assessed for its suitability to be used for modelling of environmental impacts by antimicrobials used in aquaculture.

However, although antimicrobial resistance development is voiced as a serious global concern, there is a lack of consensus in the scientific community how to assess the scale of impacts of AM use in aquaculture. The time-scale and geographical scale is of important consideration, as few local short-term risks can be identified with the use of AMs in aquaculture. However, the mechanisms of AMR development in aquatic environments, dispersion and interconnectedness with human food sources, are of long-term global concern.
