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.

Prisca Odero awarded ASA Presidential Fellowship

Dr Prisca Odero, a Centre for Africa Studies (CAS) fellow, received the African Studies Association (ASA) Presidential Fellow award in Indianapolis, USA, recently.

She was nominated for ASA by Dr Cyril Obi from the Social Science Research Council (New York), and was selected competitively, based on her PhD thesis and applied research work in rural development in Africa. Odero obtained her PhD in Africa Studies from the UFS at the July 2014 Graduation Ceremony.

On 22 November 2014, Dr Odero gave a public lecture at the Brooklyn College of the City University of New York. The event was hosted by the Political Science Department at the College.

Her paper, titled Sources and role of social capital in smallholder agricultural production: The value of membership of community groups to Zimbabwe rural livelihoods, sought to address the question of whether social capital contributed to the resilience of rural households in the face of economic difficulties and food security challenges. Dr Odero argued that the link between social capital and agricultural production is manifest in the ways in which farmers use social capital derived from membership of groups to alleviate agricultural production challenges.

Smallholder farmers in Zimbabwe, who face constraints in acquiring the necessary resources for production because of failing markets and reduced agri-industry productive capacity, employ a range of methods to deal with these challenges.  She presented an analysis of data collected through focus group discussions with representative groups and through a household survey.

Dr Odero’s research forms part of a book project. While books on agricultural development knowledge do exist, more studies analysing issues and offering solutions from an African perspective would help to address the gap in African knowledge production.
