NRF African Origins Platform Project: 2022 – 2024

ABSTRACT: The southern margin of South Africa hosts an extraordinary array of global biodiversity hotspots and an associated archaeological record that provides some of the earliest evidence of our species’ evolution to behavioural modernity. Combined, these aspects of South African natural and cultural heritage have made the region a focal point of both national and international research initiatives in recent decades. Logically, scientific initiatives have been centred on 1) modern ecology and 2) archaeology, reflecting the most obvious aspects of regional interest. However, despite the important discoveries and advancements that have been made, vital knowledge gaps remain. Most notable is the lack of information regarding the climatic and environmental drivers that have contributed to the evolution of regional biodiversity, and how these changes and this diversity influenced the evolution of our ancestors. This project will develop knowledge of past climate and environmental change along Africa’s southern margin and enable a fusion of disciplines for a more comprehensive understanding of both biodiversity and human-environment interactions in this fascinating region. To this end, this project will encompass the globally unique biodiversity hotspots of the Cape Floristic Region and Maputaland-Pondoland-Albany Region, collecting palaeo-archives across key environmental gradients. These archives, including both sediment cores from lakes and wetlands and rock hyrax middens, will be analysed within a multi-proxy, multi-disciplinary framework, using pollen, fungal spores, micro- and macrocharcoal and geochemistry to elucidate changes in vegetation, herbivory, fire, hydrology and climate. This work is designed to actively develop regional capacity, using the new Palaeolab at Nelson Mandela University and engaging students and early career scientists from the area to contribute to this development of fundamental knowledge regarding their environment and history.

Project Highlights

2022

Southern Cape interior fieldwork We participated in a very successful hyrax midden recce fieldtrip to the Klein Karoo. Mandela Uni students learnt what middens look like in situ and how to spot them from a distance.

Palynological Training Workshop: To meet one of the overarching goals of the project – to build capacity and enhance the transfer of specialised skills – a comprehensive training workshop for the Palaeolab’s postgraduate student group led by Dr Saúl Manzano at his institution the University of León, in Spain took place from 11 – 15 July 2022.

The workshop integrated both lecture and practical components with several palaeoecology-themed guest seminars, together with intensive palynology training sessions centred on the identification of Cape pollen types.

The workshop not only massively accelerated the uptake of fundamental palynological training (not available in South Africa) but also represented an excellent opportunity for Mandela Uni students to participate in an international scientific initiative and to develop and strengthen their research careers.
