In the field of agriculture, the scientific community has followed studies on methods and tools to meet the growing need to reassess agricultural operations and therefore to judge the degree of deterioration and pollution of natural capital. In this study, the IDEA method -which is Farm Sustainability assessment method-, was used to meet this objective, at Mornag area in Tunisia. This detailed analysis based on the factor: farm size, allowed us to identify the characteristics of the different groups and the adaptation strategies for agricultural sustainability upon three scales: agro-ecological, socio-territorial and economical scales. The results showed that the overall scales’ scores at each group are positively affected by the size of the farm. Indeed, the detailed analyzes of the scores of indicators and components showed that the land size turned out to be a limiting factor against sustainability. It is therefore useful to take into account the failures that are detected at the different indicators and components in order to try to improve production systems and to facilitate the transition to sustainable agriculture able to combine economic efficiency and to reduce ecological costs.
