Mapping Ancient Africa: Rome workshop

July 14, 2023
WDG

The Mapping Ancient Africa workshop took place at the Royal Netherlands Institute in Rome on the 12 and 13 July 2023. Participants engaged with two different approaches to palaeoclimate modelling:

Interfacing palaeoclimate models through the “pastclim” R package. Lead by Michela Leonardi.
Reconstrucing palaeclimate on the basis of ancient pollen data using the CREST program. Lead by Manu Chevalier.

The aim of the workshop was to promote interaction between scientists working across Africa and across disciplines (palaeoclimate, palaeoecology, archaeology, modelling). The plenary session was joined by participants who could not make it to Italy via Zoom. This session was recorded and you can watch it below. In the plenary session outputs from the workshop, the planned special issue of Quaternary International, and the future of the Mapping Ancient Africa project were discussed.
