(Bichel Committee 1999) concerned conversion to 100% organic farming
in Denmark and the resulting ban on the use of both pesticides and
synthetic fertilisers. In this study, the following three theoretical scenarios
for 100% conversion to organic farming within a thirty-year time horizon
are considered (Alrøe
et al.
1998):
Full national self-sufficiency with fodder (
i.e.
no import). This
particularly limits the pig production, because it was assumed that the
total Danish milk quota would still be produced after conversion.
15% import of fodder for ruminants and 25% import for non-
ruminants. Here the pig production is limited too, but less than in
scenario A.
The same level of animal production after conversion as in 1996
(unlimited import of fodder).
In this chapter, crop production on the ha agricultural
area of Denmark is simplified to consist of grass/clover, cereals, row crops
and permanent grass. For each crop type, the yield is estimated in
for the present practice on organic Danish farms (Halberg and Kristensen
1997), and for an expected improved future practice (Table 13.1).
For example, the potential for yield improvements in organic
cereals and grass/clover are expected to be 15% and 10%. From this the
corresponding livestock production in
and fodder
import is
estimated (Table 13.2).
