IFAS-Research mission in Botswana: visiting Gcwihaba Caves 🦇
1️⃣ & 2️⃣ In March, the director and the project and communications officer of IFAS-Research went on a mission in Botswana to visit the archaeological fieldwork of Laurent Bruxelles (IFAS-Research, CNRS) at the Gcwihaba Caves.
This fieldwork is part of the international programme Homini’Karst, supported by IFAS-Research since its beginning, in 2021. Gathering a dozen of students and researchers in archaeology, palaeontology, geology and geography, from various institutions in France, Botswana and Southern Africa, the programme aims to identify and analyse new fossil-bearing deposits to understand human evolution.
3️⃣ After survey and excavation campaigns, the March 2026 mission was dedicated to studying the palaeo-environement, in partnership with the geologists Dr Marc Jolivet (CNRS, Géosciences Rennes), Prof. Olivier Dauteuil (University of Rennes) and the Okavango Research Institute. The latter are leading a study of the Okavango Delta palaeoenvironment to which the Gcwihaba Caves formation is connected.
4️⃣ The team collected bat guano coring in several caves of the region, including Gcwihaba Caves. For her thesis, Ms Tshwanelo Gkagosana, PhD student at the Wits - University of the Witwatersrand, will study the pollens present in each guano stratum, to reconstruct the past environment of the region.
5️⃣ Twelve students from the University of Botswana Faculty of Humanities, supervised by Dr Cynthia Mooketsi, were trained in speleology and geology and were presented the research topics of the programme’s lead scientists.
6️⃣ A documentary film crew followed the researchers during the mission. The documentary, planned to air on France 5 in 2027, will focus on the Okavango environment, including Gcwihaba Caves, and how it was formed.
