Key Data Set Information
Location SY-LN-CN
Reference year 2016
Name
Northeast Rice Production ; Rice Cultivation
Use advice for data set When using this data for life cycle assessment, ensure that the system boundaries are correctly applied. The data covers from the mining of raw materials for fertilizers and pesticides production up to the emission of pollutants during the rice cultivation phase. Users should integrate this data with information about downstream processes if the full life cycle of rice is to be considered. Pay attention to the technological applicability, especially concerning the equivalent coefficient method when converting the environmental impacts, as methodology may differ according to the goal and scope of the study.
Technical purpose of product or process The data set represents the life cycle of rice production in Northeast China. It indicates the agricultural process of rice cultivation which involves the use of chemical fertilizers and pesticides, machinery fuel consumption, electricity consumption for production, and irrigation water usage. This data is relevant for studies on environmental impact assessments of agricultural practices, particularly in the context of rice farming in the specified region.
