INQUA Fellowship Award: Alfred Houngnon

December 20, 2023
WDG

I am delighted to be able to report that Alfred Houngnon (University of Abomey-Calavi, Benin) has beenawarded an INQUA Fellowship for 2024 to develop his research into past environmental change in the Dahomey Gap. This research will link up my laboratory, at the Institute of Biodiversity & Ecosystem Dynamics (University of Amsterdam), and the group of Dr Mireille S.S. Toyi (Laboratory of Applied Ecology, University of Abomey-Calavi). Below, and in the associated video report, Alfred explains the project and what he hopes to achieve during the project.

The Dahomey Gap project is designed to gain new insights on the West African palaeoenvironments using pollen, charcoal and dung fungal spore records to reconstruct past vegetation, fire and animal abundances. These empirical data will then be compared against paleoclimate models. Specifically, we will explore the interactions between fire, animals and vegetation around the Ewe-Adakplame forest in the south east of Benin Republic and highlight the role humans would have previously played in the modification of the landscape for millennia.

Mapping Ancient Africa: Structuring a scientific article

December 19, 2023
WDG

INQUAlogo

The Mapping Ancient Africa (MAA) project is currently (late 2023 until early 2024) in the process of collecting submissions for a special issue of the INQUA (our sponsors) journal Quaternary International. The special issue will showcase research developed at the MAA workshop in Rome, and presented at the MAA sessions at the INQUA Rome congress. However, the editorial team is open to considering manuscripts relevant to the MAA goals that come from people not already involved in the project – so please contact us if you have ideas.

The process of developing articles for the special issue will be supported by the MAA community through a series of events. The first of these was a online workshop (2 October 2023) set out the frame of reference for the special issue, and included a short presentation on tips for structing a scientific article for this journal. If you missed the event and are thinking about writing an article for the special issue, or in a similar style, you can catch up with this on the Ecology of the Past YouTube channel. In person writing workshops are planned for 2024 in Africa. As full details emerge information will be published here.
