The present study investigates the value chain supplying school catering with organic produce, using the organic vegetable industry in the Berlin-Brandenburg region as an example. It employs a qualitative case study approach to explore industry actors’ perspectives and their activities within the value chain. Data is collected by conducting ten in-depth interviews with actors on different supply chain levels (farming, wholesale, and school catering) and is analyzed using qualitative content analysis
Invasive species such as Ambrosia (an annual weed) pose a biosecurity risk whose management depends on the knowledge, attitudes and practices of many stakeholders. It can therefore be considered a complex policy and risk governance problem. Complex policy problems are characterised by high uncertainty, multiple dimensions, interactions across different spatial and policy levels, and the involvement of a multitude of actors and organisations. This paper provides a conceptual framework for analysing the multi-level and multi-actor dimensions of Ambrosia management.
