Ecological Footprint Analysis (EFA) is an environmental accounting system that provides an aggregate indicator which is both scientifically robust and easy to understand by non-experts. Although based on the lifestyle consumption of natural resources, recent improvements in the methodology now allow the application of EFA to a final product. Thus the resulting footprint value represents the environmental cost of all of the activities required to create, use and/or dispose of a particular product. The application of EFA to agricultural systems is still uncommon and examples in the fruit sector rare. In this work a detailed application of EFA to a commercial nectarine orchard in Piedmont (Italy) is presented. In contrast to previous studies, we considered not only the one-year field operations, but also the whole lifetime of the orchard. The calculation was conducted for six different orchard stages: (ST1) nursery propagation of the young plants; (ST2) orchard establishment, (ST3) young trees producing low yields, (ST4) mature trees at full production, (ST5) declining trees with low yields, and finally (ST6) orchard removal. The environmental costs at each stage are presented and related to each other on the basis of the relative footprint value. Results highlight the importance of applying EFA to the entire lifecycle of orchard production: ST4 accounted for the majority of costs at 65% followed by ST2, ST3 and ST5 at or near 10%, whilst the costs of ST1 and ST6 were negotiable. Thus it is the type of ST4 production used which can have the greatest impact on EFA values.

Abstract
Ecological Footprint Analysis (EFA) is an environmental accounting system that provides an aggregate indicator which is both scientifically robust and easy to understand by non-experts. Although based on the lifestyle consumption of natural resources, recent improvements in the methodology now allow the application of EFA to a final product. Thus the resulting footprint value represents the environmental cost of all of the activities required to create, use and/or dispose of a particular product. The application of EFA to agricultural systems is still uncommon and examples in the fruit sector rare. In this work a detailed application of EFA to a commercial nectarine orchard in Piedmont (Italy) is presented. In contrast to previous studies, we considered not only the one-year field operations, but also the whole lifetime of the orchard. The calculation was conducted for six different orchard stages: (ST1) nursery propagation of the young plants; (ST2) orchard establishment, (ST3) young trees producing low yields, (ST4) mature trees at full production, (ST5) declining trees with low yields, and finally (ST6) orchard removal. The environmental costs at each stage are presented and related to each other on the basis of the relative footprint value. Results highlight the importance of applying EFA to the entire lifecycle of orchard production: ST4 accounted for the majority of costs at 65% followed by ST2, ST3 and ST5 at or near 10%, whilst the costs of ST1 and ST6 were negotiable. Thus it is the type of ST4 production used which can have the greatest impact on EFA values.File | Dimensione | Formato | |
