The aim of this study is to evaluate the potential environmental life-cycle impacts of olives produced in three management systems of olive tree integrated with natural grassland. This study compares three small farms using different farming systems (silvopastoral, organic and traditional) with an average Italian farm using life cycle assessment methodology. The most related to agriculture impact categories were assessed: Global Warming potential, acidification and eutrophication. All farms were are using small amount of fertilisers, low use of chemicals, and no pesticides. However among all agricultural practices, fertilization has the highest environmental impact followed by machinery use. In this case organic farming system is looking as the most promising one due to low organic fertiliser application.
