Corrigendum to:A Nordic case study on connecting biomass, nutrient and energy flows from field scale to continent

In chapter 3.1, Fig. 3 and Fig. 4 the values related to livestock production are corrected Original version: 3.1. Biomass for food and feed The INT-LIV region produced 59% more food protein per hectare than the URB-CRP region, and 23% more than the GRS-LIV (Fig. 3). In both the GRS-LIV and INT-LIV regions, protein was produced mostly in the form of livestock products whereas, in the URB-CRP region, it was mostly produced in the form of crops. As a net balance, the INT-LIV and GRS-LIV produced more food protein than they consumed while the URB-CRP was the most reliant on food protein imports (Figs. 3 and 4). In the GRS-LIV, 97% of the livestock-based protein produced was in the form of beef or milk. In the INT-LIV the corresponding proportion for bovine production was 47% and in the URB-CRP it was 78%. Cereals corresponded to 94% of the total protein in food crops in the URB-CRP. In the GRS-LIV and INT-LIVE the corresponding shares for cereals were 75% and 58% respectively. In the INT-LIV and GRS-LIV potatoes produced 42% and 22% of the total food crop protein. Feed self-sufficiency was highest in the URB-CRP region, where on-farm concentrated feeds were produced 52% more than consumed (including the cereals in industrial feeds). The quantity of surplus feed protein (kg ha−1) was 23% higher than the produced food protein in the URB-CRP while in the GRS-LIV and INT-LIV there was a deficit in concentrated feed production (Fig. 4.) Corrected version (corrected values in bold numbers): 3.1. Biomass for food and feed The INT-LIV region produced 101% more food protein per hectare than the URB-CRP region, and 48% more than the GRS-LIV (Fig. 3). In both the GRS-LIV and INT-LIV regions, protein was produced mostly in the form of livestock products whereas, in the URB-CRP region, it was mostly produced in the form of crops. As a net balance, the INT-LIV and GRS-LIV produced more food protein than they consumed while the URB-CRP was the most reliant on food protein imports (Figs. 3 and 4). In the GRS-LIV, 91% of the livestock-based protein produced was in the form of beef or milk. In the INT-LIV the corresponding proportion for bovine production was 50% and in the URB-CRP it was 77%.

In the INT-LIV and GRS-LIV potatoes produced 42% and 22% of the total food crop protein. Feed self-sufficiency was highest in the URB-CRP region, where on-farm concentrated feeds were produced 356% more than consumed (including the cereals in industrial feeds). The quantity of surplus feed protein (kg ha−1) was 155% higher than the produced food protein in the URB-CRP while in the GRS-LIV and INT-LIV there was a deficit in concentrated feed production (Fig. 4.)
