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.
No panic as we set up for session 1…
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).
My name’s Alfred Houngnon, native of Benin Republic in West Africa. I hold an agricultural engineering degree in “Rangeland Management and Conservation” (Abomey-Calavi University). After gaining relevant field experience, I obtained a French Government Bursary to pursue an MSc degree in “Tropical Plant Biodiversity” at Montpellier (France). There, I learned about how to use indicators of past environmental and climatic change to give insights into projected future change.
It was a great scientific experience to participate in-person at the XXI INQUA Congress 2023 in Rome (Italy). This opportunity came under the supervision of William Gosling, and with the support of the Mapping Ancient Africa (MAA) project funded by INQUA’s Palaeoclimate commission (PALCOM). I have been working with Will for a number of years and published a first paper related to this work in 2021; a checklist of vascular plants from a ‘relict’ forest in Benin (Houngnon et al., 2021). A second manuscript is under development and was accepted for poster and oral presentation at INQUA 2023 congress that brought together around 4000 abstracts.

The bursary from the MAA project allowed me to also attend the MAA Rome workshops held at the Royal Netherlands Institute in Rome (12-13 July 2023). During the workshops, I was trained in two novel approaches to palaeoclimate modeling. The first based on interfacing paleoclimate models through the “pastclim” R package (Michela Leonardi), and the second on reconstructing palaeoclimates on the basis of ancient pollen data using the “CREST” program (Manu Chevalier). The workshops helped me to sharpen the communication of my ideas and in so doing strengthened the manuscript in preparation for submission to an international journal for publication.

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!
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
Quick et al. Palaeoenvironments of the Cape Floristic Region: New research & current developments
In person attendees (left to right): William Gosling (University of Amsterdam), Busisiwe Hlophe (University of Witwatersrand), Michela Leonardi (University of Cambridge), Soléne Boisard (University of Montréal), Rahab Kinyanjui (National Museums of Kenya), Trevor Hill (University of KwaZulu-Natal), Mathias Vinnepand (Johannes Gutenberg-University of Mainz), Tom Johnson (University of Massachusetts Amherst), Manu Chevalier (University of Bonn), Brian Chase (CNRS: Montpellier), Stefanie Kaboth-Bahr (Free University of Berlin), Markus Fischer (University of Potsdam), Bahru Zinaye Asegahegn (University of Cologne), Alfred Houngnon (AGIR), and Jemma Finch (University of KwaZulu-Natal); present but not in photo Angela Effion (University of Witswatersrand).
A further nine participants were anticipated to attend the workshop but, due to a combination of the non-issue of visas, logistical difficulties and ill health, they were not able to attend at the last moment. These were: Aliyu Adamu Isa (Ahmadu Bello University), George Biddulph (University of St Andrews), Olugbenga Boboye (University of Ibadan), Husna Mashaka (University of Nairobi), Emma Mbua (National Museums of Kenya), Aissatou Thiam Ndong (University of Cheikh Diop, Dakar), Adisa Ogunfolakan (Leventis Museum of Natural History), Alice Paine (University of Oxford), and Lynne Quick (Nelson Mandela University). Some people were able to attend partly online. Some have now made it to Rome and we hope to catch up at the INQUA Rome congress (Session 64) if not before. We hope that all will continue to be involved with the Mapping Ancient Africa project.
The Mapping Ancient Africa workshop took place on the 12-13 July 2023 at the Royal Netherlands Institute in Rome. At this INQUA funded workshop we played with palaeoclimate models and discussed past environmental change across the continent. Here are some picture of us in action. To find out more click here.
Day 1: Modelling past climate through the pastclim package, and reconstructing past climate through CREST
Day 2: Planning the proposed special issue and the future of the project
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.

The Mapping Ancient Africa (MAA) workshop in Rome will take place on the 12 and 13 July 2023. The workshop supported by International Union for Quaternary Research (INQUA) and hosted by the Royal Netherlands Institute in Rome. During the workshop we will be working towards aims of the MAA project to strengthen the research community of Quaternary scientists working across Africa, and to further our scientific goals of understanding past climate change. To achieve this we will work collaboratively to:
simulate past climate change in Africa,
develop the proposed Special Issue of Quaternary International, and
plan the next steps for the MAA project.
Twenty-seven people are registered for the workshop and we look forward to seeing them in Rome. If you are not registered for the workshop but still want to participate this is possible. On the 13 July between 15:00 and 18:00 CEST the workshop sessions will be online via Zoom. To obtain the Zoom link either visit the MAA Slack channel, or contact William Gosling. During the online part of the meeting we will present the outputs from the palaeoclimate mapping activity, the plans for the special issue, and outline the ideas future of MAA. Feedback from the wider MAA community will be very welcome.
The seminar delivered by Emma Mbua (National Museums of Kenya) on the 13th April 2023 was the twelfth in the Mapping Ancient Africa series. The seminar highlighted new finds from archaeological sites in eastern Africa that have yielded bones of various animals, including early humans.
