Mapping Ancient Africa: Video of seminar 17

May 17, 2024
WDG

The 17th online Mapping Ancient Africa seminar took place on Thursday 16 May 2024. The seminar was delivered by N’dji dit Jacques Dembele and was entitled “Evidence of recent seismicity in the West African Craton: The Bamako seisemites Mali”. In the seminar surprising new evidence for Quaternary seismic activity within the West African Craton – which was thought to be tectonically stable – was presented. Specifically, the identification of clastic dykes and deformation within sedimentary and lacustrine deposits was used to suggest past high magnitude earth quakes in the last 170,000 years.

The 16th Mapping Ancient Africa seminar took place online on Friday 12th April 2024. The seminar was delivered by Stéphanie Bodin (Senckenberg Research Institute and Natural History Museum Frankfurt). In the seminar Stéphanie demonstrated how the examination of ancient charcoals found in caves used for shelter by hunter-gather populations living in Ethiopia at the end of the African Humid Period (4,000-2,000 years ago) can provide insights into vegetation and human selection of woody resources.

The 15th Mapping Ancient Africa seminar took place online on Friday 15th March 2024. The seminar was delivered by Bruk Lemma (Martin Luther University Halle-Wittenberg, Germany; Ethiopian Biodiversity Institute – EBI). In the seminar Bruk presented recent advances made in the application of biomarker and stable isotope techniques in revealing the climate dynamics of the Bale Mountains in Ethiopia. He showed that it is possible to identify some plant types using these approaches, but that degradation of the signal in the sedimentary environment is possible.

Mapping Ancient Africa: Writing workshop 2024

March 7, 2024
WDG

A workshop will be held at the National Museums of Kenya (Nairobi, Kenya) in June 2024. The aim of the workshop is to help authors prepare articles for the Mapping Ancient Africa (MAA) special issue proposed for publication in Quaternary International and lead by Dr. Stefanie Kaboth-Bahr. The workshop will be associated with the “1st Joint International Scientific Conference” (3-6 June). The MAA workshop is being organized by Dr. Rahab Kinyanjui, and the congress organization is being lead by Dr. Emmanuel Ndiema (click here to watch his 2022 MAA seminar) and Dr. Esther Kioko (Acting Director National Repository and Research).

For further information on attending the MAA workshop please contact Rahab directly.

Mapping Ancient Africa: Scientists

During the Mapping Ancient Africa workshop in Rome I conducted short interviews with the scientists involved. The first of these, Alfred Houngnon can be viewed here, below are four more, and more will follow as I get them uploaded. I hope they provide interesting insights into the diverse range of skills and backgrounds our scientists have.

Interview 2: Busisiwe Hlophe (University of the Witwatersrand)

Interview 3: Angela Effion (University of the Witwatersrand)

Interview 4: Bahru Zinaye Asegahegn (University of Cologne)

Interview 5: Michela Leonardi (University of Cambridge)

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.
