spinach production, UPR, ecoinvent 3.6, Allocation, cut-off
Reference product: spinach [kg]
Location: GLO - Global
This dataset represents spinach production according to the Integrated Production standard in CH.
Yield: 25 t / ha.
Duration of one cropping cycle: 1.25 months.
The LCA study, from which this LCI has been derived, contains detailed descriptions of the system boundaries and the data sources used (Stoessel et al. 2012). The publication is published and freely available with comprehensive supporting information:

This activity was adapted to include the global average land use change (LUC) emissions according 2nd edition of the Quantis-modified tool developed by Blonk Consultants 'WFLDB-adapted-Blonk 2014 direct-land-use-change-assessment-tool_2015-05-18a.xlsx', tab. 'Country & land use unknown'. The size of the emission depends on (i) the relative crop expansion in all countries of the crop during the last 20 years and (ii) the corresponding, country specific land transformations. The current results are based on the average FAOSTAT data (harvested area) of 2009-2011 and 1989-1991. The weighted average is used which takes into account relative difference in crop expansion into primary forest, secondary forest, grassland, perennial and annual land.
[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
Version 3 of the ecoinvent database offers three system models to choose from. For more information, please visit: https://www.ecoinvent.org/database/system-models-in-ecoinvent-3/system-models-in-ecoinvent-3.html)]
