FSSIM and its components
in farming systems. Based on FADN and Farm Structure Survey (FSS), this farm
typology provides for each region in the EU (so called NUTS2 regions) a set of
typical, well defined farm types in terms of size (i.e. total available agricultural
land), intensity of production (i.e. output per hectare), land use and specialisation.
The thresholds that are used to allocate farms to a specific farm type are the same
for all Europe.
A spatial allocation procedure was also used for allocating the farm types to
spatial units, with more homogenous bio-physical endowments (Chapter 7, this
Volume). The aim was to enable the aggregation of farm types to both natural
(territorial) and administrative regions. Each farm type of the SEAMLESS farm
typology is linked to a number of agri-environmental zones defined as a combination
of climatic conditions, soil characteristics and other geographical attributes.
Representation of the Farm Type: Average Versus Typical Farm
The farm type consists of a group of farms with similar socio-economic and
agri-environmental characteristics. To simulate the behaviour of a certain farm type
with a farm model (like FSSIM) it is important to select/construct a farm that represents
adequately the whole group of farms that are classified in the same farm type.
