Digging up truth South Africa was way different to what you thought
Archaeological excavations in the Wonderwerk Cave, north of Kuruman in the Northern Cape.

Research fellow Dr Lloyd Rossouw from the Department of Plant Sciences at the University of the Free State (UFS) recently published an article in the Nature Ecology and Evolution journal with Dr Michaela Ecker from the University of Toronto as lead author, and Dr James Brink, research fellow at the UFS Centre for Environmental Management. The findings described in “The palaeoecological context of the Oldowan-Acheulean in southern Africa” provides the first extensive paleoenvironmental sequence for the interior of southern Africa by applying a combination of methods for environmental reconstruction at Wonderwerk Cave, which have yielded multiple evidence of early human occupation dating back almost two million years ago.

Where water once was
The Wonderwerk Cave is found north of the Kuruman hills (situated in Northern Cape) a 140m long tube with a low ceiling. The surroundings are harsh. Semi-arid conditions allow for the survival of only hardy bushes, trees, and grasses. But during the Early Pleistocene, stepping out of the Wonderwerk Cave you would have been greeted by a completely different site, the researchers found. Using carbon and oxygen stable isotope analysis on the teeth of herbivores (Dr Ecker), fossil faunal abundance (Dr Brink), as well as the analysis of microscopic plant silica remains (phytoliths) excavated from fossil soils inside the cave (Dr Rossouw), the results show that ancient environments in the central interior of southern Africa were significantly wetter and housed a plant community unlike any other in the modern African savanna. 

What difference does it make?
While East African research shows increasing aridity and the spread of summer-rainfall grasslands more than a million years ago, the results from this study indicate an interesting twist. During the same period, shifts in rainfall seasonality allowed for alternating summer and winter-rainfall grass occurrences coupled with prolonged wetlands, that remained major components of Early Pleistocene (more or less the period between one and two million years ago) environments in the central interior of southern Africa. That means our human ancestors were also living and evolving in environments other than the generally accepted open, arid grassland model.

“This new development will strengthen the long-lasting collaboration between DiMTEC and the United Nations University, Institute for Environment and Human Security (UNU-EHS) in Bonn in Germany. This [collaboration] goes back for almost a decade of joint training courses and increasingly also includes collaboration in the frame of scientific projects, especially in Africa.”

These were the words of Dr Joerg Szarzynski after his appointment as Affiliated Associate Professor to the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State (UFS). Dr Szarzynski will assume his new position with immediate effect.
 
The United Nations University (UNU) is a global thinktank and postgraduate teaching organisation headquartered in Japan.

Dr Szarzynski, head of the EduSphere section and Education Programme Director at UNU-EHS, brings with him a wealth of experience, including serving as senior expert to the United Nations Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER). Within the team, he was principal desk officer for Africa responsible for relief activities after natural disasters, technical consultation, information management, collaborative network development and the cluster on health and climate change adaptation. He also has broad expertise in climatology and remote sensing, global environmental change research, capacity-building and web-based data and information management.

“Dr Szarzynski’s appointment brings
new research opportunities.”

Lecture focus on vulnerability and disaster risk reduction
As part of his new academic responsibilities, Dr Szarzynski will conduct face-to-face lectures during a course on vulnerability and disaster risk-reduction. With this course the centre aims to increase awareness of the complexity and importance of vulnerability and resilience in the field of disaster risk management. Dr Szarzynski’s teachings will focus on Early Warning Systems and Geospatial Technologies in Support of Disaster Risk Reduction (DRR) and Emergency Response Preparedness. He will also lead courses on Assessment and Coordination in International Disaster Management and Humanitarian Response and Information Technology in Disaster Risk Reduction and Disaster Management.

Furthermore he will give lectures via distance learning for the wider curriculum at DiMTEC.

Collaboration between DiMTEC and UNU
Dr Andries Jordaan, Director of DiMTEC at the UFS said: “His appointment opens new networks within the United Nations system, which brings new research opportunities. Furthermore, his expertise is important to us. He has already provided input and delivered lectures through Skype in the course of Information Technology and Communication.”

Dr Szarzynski has been lecturing for the past 10 years in the UFS’ international PhD curriculum.
