Handessi Horizon adaptation to increasing aridity
Pastoral communities increasingly incorporated sheep and goats, while lower Wadi Howar became less suitable for permanent settlement.
What is the evidence?

Interpretation and caveats
The change represents gradual adaptation and altered mobility rather than a single collapse. The lower wadi continued to be used after permanent settlement declined.
