System analysis
Holistic analysis of systems, components and interrelationships
… using a life cycle perspective
… to understand how interactions yield system level behavior
… and mechanisms may change system behavior

Life cycle process model of fishing gear

Norway as a case study
• 25 000 km coastline
(100 000 including islands)
• Over 600 fishing ports
• 2.6 million tonnes seafood
exported annually

Approach
7
Annual Material Flow Analysis of Plastics (PP, PE & Nylon) from Commercial Fishing Gears Deployed in Norway
8
Mechanisms to change system behavior and
performance
Technical, financial,
regulatory and/or practical
measures aimed at
eliminating, reducing or
reversing derelict fishing
gear mass flows
• Reward schemes
• Extended producer responsibility
