shows how two different farm types respond to the policy and baseline
scenario, in comparison with the base year. Compared to the base year 2003, the
farm income decreased in the baseline 2013 for the two farm types respectively
with ca. 25% and 20%, mainly because of reduction of premiums. The environmental
impacts in terms of nitrate leaching, soil erosion and pesticide consumption
(average at farm level weighed by area per crop) seem positive due to the drop in
the area devoted to cereals (mainly durum wheat and irrigated maize) and the
increase in area of protein crops which are more efficient from an environmental
point of view. The policy scenario tested in this example had a modest impact on
farm income and nitrate leaching, in comparison with the baseline scenario, due to
the limited impact of the policy proposal (G20) on the price of the major arable
products as simulated by the market model.
Simple or Summarized Application of FSSIM
To enable upscaling of farm type analysis to the EU through the assessment of
price-supply relationships (Pérez Domínguez et al.
2009)
, FSSIM is used with
simple or summarized data. The data needs of FSSIM for the simple survey regions
should be restricted to what is available in EU wide databases and the simple survey
of current activities which was conducted within SEAMLESS to identify the
currently used activities and the corresponding technical coefficients.
The purpose of this section is to describe a simplified version of FSSIM that can
be used for analysis at EU level and to illustrate the type of analysis by presenting
some preliminary results from application to Flevoland.
