I am pleased to announce the start of a new project “Mapping Ancient Africa” funded by the International Union for Quaternary Research (INQUA) with support from the Palaeoclimate commission (PALCOM) and the Human & Biospheres commission (HABCOM). This project will bring together Quaternary scientists focused on past climates and environments with those working on human evolution and development in Africa. Through the synthesising data and linking these with modelling approaches we hope to bring together a novel group of researchers to explore the climatic and environmental backdrop to hominin development.
Further information on the project can be found on a new “sub-site” within this blog dedicated to the “Mapping Ancient Africa” project. The project is designed to connect researchers working on these topics so if you are interested to be involved please do get in contact. The first meeting will be held in October 2021 online and at four locations: Nairobi (Kenya), Port Elizabeth (South Africa), Potsdam (Germany) and Portland (Oregon, USA) – for further details click here.
As part of the (on-line) bachelor level “Big History” course from the Institute for Interdisciplinary Studies at the University of Amsterdam I recently recorded a podcast with Henry Hooghiemstra. Under the banner of “How Has Climate Change Influenced History?” among other things we discussed: (i) the principles of how we can obtain information on past climatic and environmental change, (ii) how global climate changed between cold (glacial states) and warm (interglacial states) during the last 2.6 million years (Quaternary), and (iii) past human impacts and influences on environmental and climatic change.
As a palaeoecologist and biogeographer I am delighted to have become a Subject Editor for Plant Ecology & Diversity (PE&D). In my new role for the journal I hope to handle a broad range of articles within my area “Global Change & Vegetation Dynamics: Past, Present & Future”. As Subject Editor, as well as organizing general submissions, I would also like to promote a range of articles focused on scientific themes that build upon key publications.
The first of these themes will be “long-termecology” and will build upon the recent ‘monster’ Grubb Review written by John Birks (Birks, 2019). The Birks manuscript covers a vast range of topics centred on the contribution of Quaternary botany to understanding modern ecology and biogeography. Topics covered within the Birks manuscript include:
Vegetation range shifts
Human impacts on ecosystems
I plan to pull together the “long-term ecology” set of manuscripts for PE&D during 2020, and contributions are welcome on any of the issues and research areas highlighted in the Birks manuscript.

I am pleased to announce the opening up of a new DPhil position at the University of Oxford Department of Earth Sciences that I will be involved with. The main supervisor for the project is Prof. Tamsin Mather and the position is part of her recently funded European Research Council project. The project is entitled “Sniffing out global volcanic fingerprints using mercury in Quaternary sedimentary records”.

Abstract submission is now open for INQUA 2019 in Dublin Ireland (25-31 July 2019). Please consider submitting to the special session I am co-organizing on landscape change in the tropics. Submissions welcome from the fields of biogeography, palaeoecology, geomorphology, volcanology, and archaeology. Click here to submit your abstract.TITLE: The changing tropical landscape
ORGANIZERS: William D. Gosling and Crystal N.H. McMichael (University of Amsterdam)
Eighteenth century explorers marveled at the diversity of tropical ecosystems seemingly untouched by human activity. As a result of these observations, the notion of tropical stability, in terms of vegetation and climate, came to underpin theories of evolution, ecology, and biogeography. Gradually, however, it has become apparent that tropical landscapes have changed markedly through time in response to global climate cycles, (a)biotic factors, and human activity. For example, Continue Reading
The final day of talks at AFQUA 2018 took a more applied approach in the first session “Applying the Quaternary: The role of the past in supporting the future”. This session focused on how we can focus Quaternary science to produce outputs that directly meet concerns and needs of society. Examples included the quantification of the fossil charcoal record to provide insights into the nature and impact of fires in the past (C. Adolf), how we can use information on past vegetation change and disturbance factors to anticipate how ecosystems on Madagascar might respond to future changes (E. Razanatsoa), and how climate histories can be extended through tree ring data (D. Colombaroli).
My first AFQUA conference really began the day before the conference proper started in the Kenyan immigration queue where I met a number of fellow delegates who were flying in from all over the world. It was great to start to put faces to names of people who’s work I had read for many years. Once out of the airport transfer to the hotel was smooth, and it was with some excitement that the following morning I made the short walk from the hotel to the famous Nairobi National Museum for the start of the conference.
Prof. Andy Cohen (one of my fellow delegates in the immigration line) kicked off the AFQUA conference with a plenary giving an overview of African continental drilling projects. He traced the dream of the recovery of long continental records back to Daniel Livingstone and Neil Opdyke’s workshop from 1980 that set out the dream of obtaining long records from the continent. He then went on to give examples of how multi-millennial lake records, including Lake Malawi, can be used to understand the tempo of ecological change.
The first session of the conference, entitled “East Africa”, included: exciting evidence of Deinotherium the largest land mammal of the Quaternary (J.-P. Brugal), the use of d13C in determining homonin ecology (V.M. Iminjili), and evidence from a new c. 200,000 year old site at Natodomeri (Kenya) that contains evidence of homonids, elephids, giant lions and pigmy hippos (F.K. Manthi).
The second session of AFQUA covered “The environmental context for homonin evolution and dispersal”. This started with geochemical data from Chew Bahir that sheds light on potential drivers of climatic shifts (F. Schabitz), and included examination of changes climate between c. 500,000 and 320,000 years ago that coincided with the shift from hominid use of large cutting tools to smaller implements (R. Potts), and discussion of the environment the route which hominids took out of Africa (F. Henselowsky).
