Reference product: land tenure, arable land, measured as carbon net primary productivity, perennial crop [kg]
Location: PE - Peru
This dataset represents the interventions associated with the provision of 1 kg NPP0 (Net Primary Production) by land that is already in use.
NPP (net primary productivity of a given land, in kg C / m2 and year) and VEG (above-ground biomass) values are parameterized.
NPP values are reported by Haberl et al. (2007)
VEG values have the following sources:
- Forests: Global Forest Resources Assessment 2010: http://www.fao.org/forestry/fra/fra2010/en/
- Grassland: IPCC 2006 Guidelines, Voiume 6, Table 6.4. All values in tonne C/ha, converted to carbon based on 47% carbon content of dry matter biomass (see for example section 188.8.131.52 of IPCC 2006).
- Crops: Cveg croplands, based on Table 11 of the European Commission decision.* All values in tonne C/ha.
* C(2010) 3751: COMMISSION DECISION of 10 June 2010 on guidelines for the calculation of land carbon stocks for the purpose of Annex V to Directive 2009/28/EC, Official Journal of the European Union, L 151/19. Exceptions based on the Table 12 of the EC decision: Coconuts, Jatropha, Jojoba Seeds, Oil palm fruit, Sugar cane
Distinction is made between primary and secondary forests. The respective land area of each type forest is known from FAOSTAT data. Based on empirical values, it is considered that the secondary VEG is 74% of the primary VEG. The same ratio is applied as the weighted average between primary and secondary forest is always equal to the GFRA 2010 value.
[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)]
