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.

Food insecurity at university campuses a growing threat
2015-07-28

Food insecurity on university campuses in South Africa has come to the fore as one of the more pressing subjects that needs to be tackled to ensure the continuing education of disadvantaged students across the country.

On Friday 14 August 2015, the University of the Free State will host the first higher education colloquium on food insecurity on university campuses.  The one-day colloquium will take place during the Arts and Social Justice Week, in collaboration with the UFS’s Institute for Reconciliation and Social Justice Best practices will be shared, exploring the available research on student food insecurity at institutions of higher education.

Food insecurity has emerged as a pressing social justice issue affecting students countrywide. Action needs to be taken to promote the academic success of students, who will ultimately contribute to the country’s economic growth. One of the primary focus areas of the colloquium will be to establish a common practice to address this need.  Universities leaders, staff from wellness and social work departments, and SRC members from across the country who have been invited, and are expected to attend, are the University of Pretoria, the Tshwane University of Technology, North West University, UNISA, and the Central University of Technology.

Professor Jonathan Jansen will participate in a panel discussion alongside Ruda Landman and Prof Edelweiss Wentzel-Viljoen (HPCSA). This promises to be an inspiring meaningful dialogue, by asking the difficult question:  How do we change the food insecurity situation at universities?

The University of the Free State is currently the country’s leading university in addressing food insecurity on all its campuses through its flagship No Student Hungry Bursary programme, which has funded more than 500 students since it was established in 2011.
