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.

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.
