(1/5) Our new paper in PNAS, with @MDpetraglia, Maria Guagnin, @DesertPrehistor , and @NicoleLBoivin is out. Arabia is a fascinating place to study human-environment interactions, with its history of dramatic climate change. https://www.pnas.org/content/early/2020/04/07/1920211117">https://www.pnas.org/content/e...

(2/5) Most models of human-environment interaction in Arabia focus on the relatively intensively studied east of the peninsula. But Arabia is a big and diverse place. Synthesizing recent work by ourselves and others in northern Arabia, we show patterns vary across the region.

(3/5) Human survival strategies varied, from being highly mobile and using shifting and unpredictable water sources, through to the development of complex water management systems and oasis agriculture.

(4/5) Climate also varied considerably both spatially and temporally, and there is a lot to figure out about the dynamics of this (e.g. relative importance of different weather systems), and how climate change played out in environment and ecology. Need lot more fieldwork.
