Rapid change of climate did not cause the fall of the Akkadian Empire

The latest issue of Antiquity published a paper presenting results of biochemical analyses of human bones from a few sites situated in north-eastern Syria, and showing on this basis that in the 22nd century BC, when the Akkadian Empire was declining, there was no change in the local economy which could be a response to a long-term drought, and even if there was a temporary climate change, the local human societies survived it in a good condition.

Climate Change and State Evolution

Despite substantial evidence on the short-term effects of adverse climate shocks, our understanding of their long-term impact is limited.  To address such a key issue, research has focused on ancient societies because of their limited economic complexity and their unparalleled experience of environmental and institutional change.  Notably, ‘Collapse Archaeology’ literature has reported statistical evidence consistent with the mantra that severe droughts trigger institutional crises.  This view, however, has recently been challenged by literature summarized in the paper Climate Change and State Evolution by Giacomo Benati and Carmine Guerriero.

Ziggurat w Nippur (współczesny Nuffar, Irak), niegdyś centrum religijne południowej Mezopotamii. Nawet jeśli uznajemy wywołany przez przemiany środowiska upadek starożytnych społeczeństw, to aby właściwie ocenić pełny wpływ zmian klimatycznych i związanych z nimi zmian politycznych, musimy odpowiednio połączyć wyniki analiz nauk przyrodniczych i społecznych © G. Benati
Ziggurat of Nippur (modern Nuffar, Iraq), once at the center of a key religious Mesopotamian polity and cultic center. Even if the environmental induced collapse of ancient societies has attracted much attention, to correctly evaluate the full impact of climate change and inform policy intervention we need to properly combine natural and social sciences.
