AFQUA: The African Quaternary environments, ecology and humans
2ndInternational Conference and Workshops
14-22 July 2018-07-15 National Museum, Nairobi, Kenya

Day 2

The second day of the AFQUA conference commenced with the second session on “East Africa” and Prof. Tom Johnson asking the question “Should we drill Lake Victoria?”… and a request for ideas from people to join in with ideas for the proposals for obtaining new sedimentary records from the lake. The East Africa session continued with exploration of Lake Kivu using organic biomarkers to see if past lake ‘explosions’ could be detected (M.E. Berke) and the use of strontium isotopes to detect past climate from lakes in the Turkana Basin (H.J.L. van der Lubbe).

Before lunch the second plenary talk of the conference was delivered by Prof. Sharon Nicolson who made it very clear that the Inter Tropical Convergence Zone does NOT play an important role in controlling rainfall patterns across Africa (see Nicholson, 2018).

After lunch the first oral sessions covered “Southern Africa” and included d13C records from Bobab trees (S. Woodborne and E. Razanatsoa), early human finds in cascade tufas (M.A. Pickford), and quantitative climate reconstructions from pollen using the CREST software (M. Chevalier). After the break we were back for “Quantitative palaeoclimatology, modelling and data-model comparison” thinking about what is abrupt (M. Claussen), the impact of atmospheric CO2 on plants (V.J. Hare), and connectivity between lakes in the Kenyan rift (R. Dommain). Then it was off to the hotel bar to watch the football…
