Unlike the irrigated south,
northern Mesopotamian societies engaged in dry-farming - that is, rain-fed agriculture.
ArchaeoSim simulates the population and agricultural dynamics
of ancient Subir, the dry-farming region of
northern Mesopotamia, from 2600 to 1728 BC. The simulation models farm area,
grain yields, population growth and immigration, grain stores, some migration
of non-farm labor from smaller sites to larger, and a simple model of
agricultural surplus production. The data driving ArchaeoSim is a high resolution archaeological
survey of the Leilan survey region, a 30 km transect of 1900 sq kms in NE Syria, spanning the Khabur triangle from
the Turkish to the Iraqi borders, giving settlement sizes and locations. This data forms the maps on the screen.
ArchaeoSim also uses paleoclimate data for rainfall levels.
Present-day dry-farming in NE Syria. Foreground is fallow field in lentils and
sunflowers. Middle ground is harvested cereal stubble. In the distance, archaeological
sites, and sheep grazing on stubble. (H. Weiss, 1984)
