The project first integrates coordination mechanisms in the sustainability assessment of agri-food chains, applying a structured literature review to develop a comprehensive framework. Then, it assesses agricultural sustainability through a cross-sectoral comparison of Ecuador's blackberry, tomato, and tree tomato sectors. Different coordination mechanisms are connected to the sustainability performance of agri-food chains in the Ecuadorian blackberry sector, so the project scaled up the sustainability assessment to a supply chain perspective. Finally, it analyzes circular economy intentions in the fruit and vegetable sector of Central Ecuador to obtain insights aimed at reorganizing and achieving a sustainable supply of fruits and vegetables.
