Solution method Optimization
Anticipation

Primary agricultural products considered in the model are listed in the following Table 1. The livestock activities are connected with the feed requirement per animal product. Following Alcamo’s work [1], the model currently considers ruminants for livestock activities such as cattle and sheep, but non-ruminants are not included. The total forage demand is calculated by multiplying livestock unit with average forage consumption per livestock unit during one year.

For the reference land use area distribution used in the base year 2011, croplands are produced by eight crop categories which contain 149 crop types (see Table 1). According to Food and Agriculture Organization (FAO) definition, grass is from permanent pastures and can be used to graze [2].
