Fig. 3: Negative associations among externality costs across 74 UK pig production systems.
From: Trade-offs in the externalities of pig production are not inevitable
a–d, Associations between land-use cost and total AMU cost (a), between land-use cost and animal-welfare cost (b) between GHG cost and total AMU cost (c) and between GHG cost and animal-welfare cost (d) across 74 UK pig systems. rs and P values were from two-sided Spearman rank correlations on a subset of our data (n = 43) with one datapoint selected randomly from those that shared breeding and/or rearing herds. Note that there are breaks in the animal-welfare cost axes due to the very low costs of one system.
