Mapping Ancient Africa: INQUA Rome – session 2

August 24, 2023
WDG

The second part of the Mapping Ancient Africa session at the INQUA Rome congress contained eight talks. Busisiwe Hlophe (University of the Witwatersrand) kicked us off by showing us the power of looking at wood anatomy preserved in charcoal microfossils to determine the nature of past vegetation and climate. Rahab Kinyanjui (National Museums of Kenya) presented phytolith work from archaeological sites revealing a mixed woody and grassy vegetation associated with archaic Homo sapiens in Kenya.

Three talks from the Cape Region in South Africa then followed with Saul Manzano (University of Leon), Stella Moscher (University of Utah), and Asithandile Ntsondwa (Nelson Mandela University) using various palaeo ecological approaches to explore climate, vegetation and fire regime shifts during the Holocene. Adele Julier (University of Portsmouth) then took us a little further north to Namibia to think about the challenges of parameterising modern pollen-vegetation relationships in arid regions. The final southern African talk was given by Gemma Poretti (University of Cape Town) explored a new approache to tracking change in past rainfall patterns using charcoal material.

On Wednesday 19 July 2023 the Mapping Ancient Africa session of the INQUA Rome congress took place. We were delighted to have an full program of speakers despite some late cancellations. The first session featured seven speakers.

The first two talks focused on southern Africa. The first talk by Liviu Giosan (Woodshole Oceanographic Institute) focused on new sediment cores extracted from the Okavango – Makgadikgadi region and new efforts to obtain sediment cores that can provide information on the dispersal of hominins. Brian Chase (CNRS) then looks us to the Karoo highlighting recent findings that suggest that this currently arid region was more habitable in the past and that a proliferation of stone tools suggests past peoples utilised the region extensively (Carr et al., 2023).

The Mapping Ancient Africa (MAA) project has a double session of talks and a poster session at the INQUA congress in Rome 2023. Our session will be on Wednesday 19 July. Unfortunately a number of the originally planned speakers could not make it to Rome due to a combination of not obtaining visas, logistical challenges and ill health. We wish them all well and hope that they will continue to be involved in the project. Further, many thanks to all those who have agreed to step up and give a presentation at a late notice. Below is an updated schedule correct as of Sunday 16 July based on the information contained on the INQUA Rome App; if you are aware of any further problems or changes please let me know ASAP!

If you are at the INQUA Rome congress please come along to our talks and posters in Session 64: Mapping Ancient Africa: Climate, Vegetation & Humans.

Giosan et al. When the desert was a lake: Providing context for Homo sapiens development in the northern Kalahari
Chase et al. Paleolakes and socioecological implications of glacial “greening” of the South African interior
Blinkhorn et al. Evaluating refugia in recent human evolution in Africa
Aureli et al. Homo sapiens behaviour and adaptation in East Africa. New evidence from an open-air site in a modern Ethiopian savannah environment: the GOT10 site
Effiom et al. Late Holocene palaeoecological studies at Lake St Lucia, KwaZulu-Natal
Tallavaara et al. Pan-African Climate and Vegetation over the Quaternary and Implications for Human Distribution

Organisms and environments: Frontiers in palaeoecological technique development

Abstract submission is now open for the XIX International Union for Quaternary Research (INQUA) Congress. “Ecology of the past” researchers will be there and are hosting a special session, entitled Organisms and environments: Frontiers in palaeoecological technique development, at which we hope to bring together a wide range of palaeoecologists working on novel proxy development. Members of the “Ecology of the past” group will be showcasing recent findings on the environmental significance of pollen chemistry change through time; linked to the 500,000 years of solar irradiance, climate and vegetation change in tropical West Africa project (Fraser et al., 2014). Please take a look at our session and consider submitting YOUR abstract today!
