I do not understand why Brazilian soybean in Ecoinvent has such a low land occupation flow. For example:
Per kg soybean:
Moto Grosso: 1.51E-4 m2.a
Bahia: 2.32E-4 m2.a
Goiás: 1.71E-4 m2.a
Paraná: 1.17E-4 m2.a
And these do not match with the yields indicated in the description. For example, for the Moto Grosso region, the yield is of 3356 kg/ha. The land occupation flow of 1.51E-4 m2.a would mean that:
Yield: 3120 kg/ha/year = 0.312 kg/m2/year.
Land required per kg: 1 kg / 0.312 kg/m2 ≈ 3.205 m2.a/kg, and not the indicated 1.51E-4 m2.a.
Even if the soybean grows during less than a year, the difference between 3.205 m2.a/kg and and 1.51E-4 m2.a is too big to be just this.
Many thanks for your help,
Best,
This suggests that producing 1 kg of soybeans would typically require approximately 3.205 m²·a of land occupation.
