Agri-food systems in transition: The role of certification in local food systems (2019-2023)
The overall goal of this PhD project is to evaluate the potential of participatory guarantee systems (PGS) - an alternative, locally focused, certification mechanism – in stimulating inclusive, resilient and sustainable local food systems. The research includes an extensive review of the scientific evidence on claims surrounding local food systems, and three case studies: vegetable value chains in Vietnam, Peru and Belgium. Micro-economic field data is collected and examined using econometric techniques, including discrete choice experiment analysis and panel data analysis.
