“…The annual yield of crops for a patch of land is determined by the soil fertility and depth, estimated from agronomic research and ethnographic studies of subsistence farming in the Mediterranean region (Thomson et al 1986; van der Veen & Palmer 1997; Araus et al 2001;Sadras & Calvino 2001;Troccoli & Codianni 2005). As noted above, the fertility of a patch decreases or increases as a patch is cultivated or fallowed, and the soil depth decreases or increases owing to erosion or deposition as calculated by the HED model.…”

“…Wheat was considered to be directly consumed in the form of bread and porridges, while barley was considered only as fodder for herd animals that produced meat and milk products to be consumed by the households. Therefore, after harvest loss, seed reserve loss, and processing loss, wheat provided agents with 3,500 kcal/Ha, while barley only provided agents with 213.87 kcal/Ha (Thomson et al 1985). In the simulation, only 50 % of the population was able to produce labor, and each productive person was considered able to produce 300 man-days per year.…”

“…Minimum yield (in a soil depth less than or equal to 13 cm) was 168 kg/Ha (Thomson et al 1985). Yields for soils of depths between 13 and 100 cm were scaled by the power regression formula:…”

“…Household agents select patches of land needed for fields and pasture, using decision algorithms informed by past farming and herding experience, household food and fuel needs, the relative importance of plant cultivation versus page 8 animal herding and perception of potential patch productivity (Mayer et al, 2006). Published studies of subsistence farming-with emphasis on the Mediterranean and xeric landscapesparameterize land-use practices in the MML, including the way land is assessed and land-use decisions made, and the caloric returns from common Mediterranean domesticates (cereals, legumes, ovicaprines, cattle, pigs) (Al-Jaloudy, 2006;Araus et al, 1997;Corbeels et al, 2000;Gibbon, 1981;Hillman, 1973;Hirata et al, 1998;Kamp, 2000Kamp, , 1987Kamp, , p. 1987Khresat et al, 2008Khresat et al, , 1998Kramer, 1982Kramer, , 1980Nyerges, 1980;Stuth and Sheffield, 1991;Thomson, 1987;Thomson et al, 1986;Ullah, 2013Ullah, , 2011Watson, 1979). Because of our focus on the initial emergence of coupled natural and human landscapes, we have emphasized modeling the first nutritionally significant domesticates in the Mediterranean region-cereal grasses (primarily wheat and barley) and ovicaprines (sheep and goats).…”
