area was partly a result of a lower production on organic farms and mainly a result of a higher
share of ruminant meat (70% compared to 30% in conventional production) which requires
more arable land compared to when producing pork and poultry. In Table 3 both per hectare
and per capita figures are presented. The latter figures are the more important ones.
Figure 1 shows the results for nitrogen surplus in diagram form for the sake of comparison
to the results presented in the following section (calculated according to method 1).

Table 3. Agricultural area required and nitrogen surplus for three scenarios: Swedish
average (mainly conventional) agriculture, ERA farms producing the average Swedish food-
basket, and ERA farms producing an alternative (ecological and more vegetarian) food-
basket. In Scenario 2, 3 and 4 all agricultural production is turned into ERA. Figures within
brackets represent are calculated with method 2, see section 2.2. Other results are obtained
using method 1.
