1 Evaluation of agricultural systems across time and spatial scales. An extended LCA approach. Amalia Zucaro, Silvio Viglia and Sergio Ulgiati

2 Introduction

3 In times of depletion of fossil fuels and minerals reservoirs, agriculture is a potential source of food, fibers, energy, chemicals, materials, jobs and landscape protection ( multifunctional role ). Problems and Challenges 1. Introduction Focus is placed on agricultural systems in order to implement opportunities and synergies and suggest different scenarios at different scales, from local to regional and national. The concept of multifunctionality expresses the inescapable link of roles and functions of agriculture with social, economic and environmental aspects.

41 Conclusion

42 SUMMAry of results The conventional LCA approach was improved (SUMMA) for Complex Systems assessment (firms, farms, production sectors, economies) Focus can be placed on different steps, time & spatial scales, and development levels Quantitative and qualitative performance indicators are designed, as a basis for policy choices Identification of bottlenecks and limiting factors is made easier Integration with MuSIASEM and ASA allows societal constraints investigation, identification of drivers of change, and finally allows alternative scenario designs. 6. Conclusion
