ABSTRACT

While minor climate change and weather effects affecting the urban and agricultural water supply of a society that influence societal sustainability can be largely countered by technological advances, major climate change results in radical realignments and transitions of existing polities’ sociopolitical economies. From derivation and use of the derived sustainability factor equation, examination the Uhle-Rowe divisions of Andean history into Horizon and Intermediate Period categories can be shown to reflect changes in climate patterns that influenced the agronomic base of major Andean polities. Intermediate values are thus a key component related to the sustainability of a society related to changes in the rainfall amounts and its effect on agricultural systems due to extended drought. Theories arise about drought periods influencing lowland agricultural vulnerabilities and population sustainability compared to highland societies and the dominance of the societies in different time periods.
