In this study, the environmental profile of rice cultivation in a farm located in Pavia district (Lombardy) fertilised with urban sewage was evaluated using the Life Cycle Assessment methodology from a cradle-tofield gate perspective. Inventory data were collected in a rice farm (102 ha) over a 3-years period. A number of environmental hotspots were identified: a) methane emissions contributing to climate change, b) emissions associated to fertiliser application contributing to acidification and particulate matter formation c) diesel requirements in field operations accounting for mineral fossil resourse depletion and d) grain drying contributing to ozone depletion. A sensitivity analysis regarding both rice yields and methane emission factors was performed in order to predict their influence on the overall environmental profile.

Abstract
In this study, the environmental profile of rice cultivation in a farm located in Pavia district (Lombardy) fertilised with urban sewage was evaluated using the Life Cycle Assessment methodology from a cradle-tofield gate perspective. Inventory data were collected in a rice farm (102 ha) over a 3-years period. A number of environmental hotspots were identified: a) methane emissions contributing to climate change, b) emissions associated to fertiliser application contributing to acidification and particulate matter formation c) diesel requirements in field operations accounting for mineral fossil resourse depletion and d) grain drying contributing to ozone depletion. A sensitivity analysis regarding both rice yields and methane emission factors was performed in order to predict their influence on the overall environmental profile.
