The study seeks to understand how circularity is measured in the agricultural sustainability tripod and which analyses are useful to assess whether circular economy strategies are more sustainable than linear economic models in agricultural production systems. Sustainable agriculture can be defined to manage agroecosystems so as to maintain biological diversity, regeneration capacity, vitality, productivity, and the ability to fulfill important ecological, economic, and social functions at the local, national, and global levels without harming the ecosystem. The systematic literature review revealed the existing interrelationships with possible exchanges and/or synergies between the different aspects of the dimensions of circular economy within the scope of agriculture. The Life Cycle Assessment methodology is the closest to quantifying a circular economy. The aspect explored within the Life Cycle Assessment regards the environment. Despite the limitations, the study evidenced how the methodologies allow a better understanding of the sustainability implications of circular economy strategies, especially when using Life Cycle Assessment. These tools have not yet been fully implemented or explored to provide a measure of circularity in a life cycle perspective.
