Evidence for Coordinated Labor in Agriculture Hypothesis of Early State Formation (CLAHSF)

Early states tended to emerge in places that were actually somewhat marginal for agriculture, quite counterintuitively. (Most recent discussion here.) When combined with the example of China (which is not at all marginal for agriculture), the connecting argument that emerges is that states appear where central coordination of labor is required for agriculture, there is a benefit to population, and a centrally organized society develops. This can occur either because of marginal conditions (e.g. timing the flooding of a river surrounded by a vast desert) or difficult crops that require more central coordination, e.g., rice. Conversely, in places where the land easily produces calories, there is little benefit to central coordination, as dissatisfied "citizens" can easily refuse to cooperate and move away, and not lose any benefit in terms of population growth.

One way to test this would be to look at political stability within an early state - within a single early state - and how stability correlates with agriculture-favoring (or -disfavoring) climate changes. This hypothesis (CLAHSF) would be falsified if improved conditions outside the central areas of a state improved state stability, and if worsened conditions outside the central area de-stabilized the state. Ola Olsson from the University of Gothenburg shows that in fact, when the ancient Egyptian "hinterlands" received better rainfall (which improved agriculture in a desert climate), there was a delayed de-stabilizing effect on the Egyptian state, "since the decline in effective circumscription provides the farming population with an outside option in the hinterland."
