This dataset is a weighted average of the regional datasets, with weights based on production volume of the reference product. Detailed comments and sources about the exchanges can be found in the regional datasets.
The geographicalCorrelation score of every pedigree matrix of was changed to '5'.
Sum of regional production volumes: 2.285e+10 kg
CN: PV = 1.586e+10 kg; weight = 0.6941
IN: PV = 6.338e+9 kg; weight = 0.2774
AR: PV = 6.509e+8 kg; weight = 0.02849
Yield of the global dataset = 2759.24309039 kg/ha, calculated as a weighted average of the regional yields.

This dataset represents the production of 1 kg of peanuts. The average yield from 2009 - 2012 is 3.5 t/ha. The data are representative for peanut production in China used for the export market. Mineral NPK fertiliser input is 80-27-28 kg/ha. No organic fertilisers are applied. Total active ingredients (a.i.) applied as pesticides amount to 11.25 kg a.i./ha.
The dataset was modelled within the project 'World Food LCA database (WFLDB)'. The aim of this project was to provide inventories of a broad variety of agricultural products and processes and to cover for each product at least 50% of the global export market. The export share of peanuts produced in China amounts to 10% of the global export (tonnage exported in 2010). The production system regarded in this dataset aimed at representing peanuts produced in China for the export market.
PEF-Quality: data quality rating (DQR) = 1.7 (i.e. very good quality). This dataset refers to an average situation; for specific situations exchanges might differ substantially due to site specific parameters
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
