WHAT IS IT?
This model represents intergroup specific violence or primitive warfare in relation to resource competition between two prehistoric palaeolithic groups, one hunter gatherer and one (possibly) semi-settled at or around site 117 near Jebel Sahaba in Nile Valley Sudan. It is possible that both groups could have been hunter gatherers. The site is dated to apporximatley 11000 years BP. In this model, the resources are unequally distributed across the land. This model is based on the image of the site from Wendorf's drawings of the time of initial excavation of the site (Wendorf, 1968).
HOW IT WORKS
(what rules the agents use to create the overall behavior of the model)
In terms of turtles, there are two types: people (black in colour) and arrows (red in colour). People could represent a semi-sedentary group and the arrows could represent hunter gatherers. As mentioned above, both groups could have been hunter gatherers. Both groups of turtles interact with the patches (grass which represents food) and each other. The turtles ‘eat’ the grass and gain energy from that. Turtles also reproduce but only with similar type. People reproduce with people and arrows reproduce with arrows.
Grass represents the overall resources available. In this model, the resources are distributed unequally across the land hence grass or food is not available in all patches. The over all value of the patches is set as zero and only specific patches have energy values higher than zero so turtles can eat from there. This is supposed to intensify the competiton for resources amongst the two groups. The energies of different coloured patches are different. The blue patches depict River Nile's fishing resources. The energy value for these patches are set at 50. The pink patches represent the narrow strip of fertile land along the river in the valley and some gullies that spread into the sandstone cliffs nearby. The value of pink patches is set as 50 as well. The turtles can only 'eat' or consume resources from pink and blue patches.
In addition, there are yellow patches which represent the sandstone cliffs. These pathces have zero energy and are also inaccessible by the turtles. This restricts the area in which turtles can move.
One of the very important things that the turtles do is ‘eat’ each other which represents killing or warfare. Turtles cannot kill the same type of turtle. People can kill arrows and vice versa. Once all of one type of turtles are killed, a message is displayed as to who won. The killing of all of one type of turtle represents the massacre or genocide that could have taken place at Jebel Sahaba where one group of people carried out repeated attacks on another group of people and they could have eventually wiped out one group to near extinction to access their resources.
HOW TO USE IT
(how to use the model, including a description of each of the items in the Interface tab)
To use this model, the user has to press the 'set up' button followed by the 'go' button. The model goes on until one group has won. There are a range of factors that can be altered as is demonstrated by a range of slider buttons. The description of the buttons is given below.
Set-up button: Use this button to reset the model to the required conditions or factors
Go button: Use this button to start the model run
Initial-number-people slider: Use this slider to alter the number of people in run/experiment
Initial-number-arrows: Use this slider to alter the number of arrows in the run/experiment
Count people button: This button counts the number of people throughout the run/experiment. The number changes as the model runs.
Count arrows button: This button counts the number of arrows throughout the run/experiment. The number changes as the model runs
Show energy switch: This switch button can be turned on or off. When turned on, it shows individual energy values associated with each turtle.
People-gain-from-food slider: This slider button shows the amount of energy people gain from eating food (which is the grass). It can be altered.
Arrows-gain-from-food slider: This slider button shows the amount of energy arrows gain from food (which is the grass). It can be altered.
Grass-regrowth-time slider: This slider button lets the user control the amount of time it takes the grass to regrow. The units are arbitrary however they are depicted as 'day' for a time reference. The time can be altered.
People-reproduce slder: This slider button lets the user control the rate of reproduction for turtles shaped as people.
Arrows-reproduce slider: This slider button lets the user control the rate of reproduction for turtles shaped as arrows.
The plot/graph: This plot shows the number of turtles, people and arrows, and number of patches in real time.
THINGS TO NOTICE
(suggested things for the user to notice while running the model)
Notice how different turtle populations interact with each other and which group wins. When running an experiment on Behaviour Space, notice which group wins and how many times.
Notice how the numbers of the two turtle populations and the different coloured patches (river and fertile land) fluctuate on the plot.
Also, notice where and how turtles move. Are they eating more and staying more towards the river and the fertile strip or are they moving more towards the gullies?
THINGS TO TRY
(suggested things for the user to try to do (move sliders, switches, etc.) with the model)
Try altering the values on different sliders and see what type of behaviour emerges. For example, try running the model with the value of grass regrowth time really low like 1 day and then try it with 100 days and compare the results. Does it make a difference in which population wins? How many ticks does it take for one group to kill the other one? What happens to the number of turtles for a particular population? How quickly do the numbers rise or fall?
Note: Make sure only one or at most two factors are altered in one experiment and the rest are kept constant otherwise the results might become too confusing to interpret.
EXTENDING THE MODEL
(suggested things to add or change in the Code tab to make the model more complicated, detailed, accurate, etc.)
To extend the model a range of different features can be added.
1 - Add an extra turtle in the shape of a cow to depict a moving herd of animals. This would be a movable resource that people and arrows can consume 2 - Add an extra turtle in a shape of a dot to depict another group of humans living near or interacting with Jebel Sahaba site. 3 - Create a model with equal distribution of resources where all patches have equal amounts of energies.
NETLOGO FEATURES
(interesting or unusual features of NetLogo that the model uses, particularly in the Code tab; or where workarounds were needed for missing features)
This warfare model is based on a Sheep-Wolf predatory model. In the Sheep-Wolf model, wolves can eat the sheep. In this model, both types of turtles, people and arrows, can eat each other. This means that they are killing each other. Moreover, since the Jebel Sahaba site seems to be a massacre site, so killing of all of one breed of turtles represents the massacre or genocide that could have taken place at Jebel Sahaba where one group of people carried out repeated attacks on another group of people and they could have eventually wiped out one group to near extinction to access their resources.
