Ahmet Candemir will defend his PhD in front of the following jury:

  • Philippe Jeanneaux (VetAgro Sup), referee
  • Leila Temri (Montpellier SupAgro), referee
  • Zohra Bouamra-Mechemache (INRAE, Toulouse School of Economics), examinator
  • Damien Rousselière (AGROCAMPUS OUEST), examinator
  • Sabine Duvaleix (Institut Agro - AGROCAMPUS OUEST, UMR Smart-Lereco), co-supervisor
  • Laure Latruffe (INRAE, UMR GREThA), co-supervisor


This PhD studies the farm sustainability by investigating the relation between sustainability components and the impacts of supply chain organisation on overall farm sustainability. The contribution of the PhD is twofold. First, the PhD takes into account the time dimension in the analysis of farm sustainability. It shows that time level evolution of environmental efforts matters in the economic performance by using farm level data from French livestock farms. Secondly, by focusing on the impacts of agricultural cooperatives in the development of sustainable practices, it shows that different types of organisational arrangement in agri-food supply chains may have significant impacts on farm sustainability. The literature review study fills the gap by providing a critical analysis on theoretical and empirical literature. It shows the diverging forms of impacts of cooperatives depending contextual and sectorial dynamics. The main conclusion of this study is shedding light on the importance of heterogeneities between and within cooperatives The PhD also shows, by studying data from seven EU countries, that choosing cooperatives as the main marketing channel may negatively affect the adoption of organic certification.
