On 25 May 2021, Africa will celebrate the 58th anniversary of the founding of the Organisation of African Unity (OAU). A central tenet of the organisation, which was the predecessor of the African Union (AU), is African solidarity. This call celebrates the idea and the ideal of African solidarity. As we are preparing for Africa Month 2021, we received the shocking news about the damage to the University of Cape Town’s African Studies collection. The need for African solidarity to mitigate this immense loss has inspired the theme of the 2021 UFS virtual Africa Month celebration, ‘solidarity in knowledge production and recording’.

From the establishment of the OAU and with the later formation of the AU, member states undertook to coordinate and intensify their cooperation and efforts to achieve a better life for the people of Africa.

Africa Day Memorial Lecture

The UFS has a long tradition of commemorating Africa Day and the ideas underpinning it. Every year, diverse events aimed at advancing African unity and solidarity take place during Africa Month –traditionally, the highlight is the Africa Day Memorial Lecture hosted by the University's Centre for Gender and Africa Studies. On 19 May 2021 at 19:00 (SAST), Prof Walter D Mignolo, a guru of decoloniality, will virtually deliver this year’s lecture titled The beauty of the sovereign people: Jean Casimir and the Decolonial History of Haiti, to honour the memory of transatlantic slavery by reflecting on former ambassador, Prof Jean Casimir, who has shifted the geography of reasoning by breaking the code of the standard history of the slave trade, the African diaspora in the Caribbean, and of captive human beings in the plantations. The discussant will be CGAS Extraordinary Professor and Professor of Epistemologies of the Global South at the University of Bayreuth, Prof Sabelo J Ndlovu-Gatsheni.  

As COVID-19 continues to ravage the world, Africans have been fighting against the pandemic in various ways and have achieved considerable success in this regard. Given the economic and social challenges associated with the pandemic, fostering African solidarity and further developing the underpinning philosophy of ubuntu appear to be particularly worthwhile projects.

A virtual celebration of Africa Month

The UFS 2021 Africa Month commemorations will again take a virtual format. It will include a focus on UFS engagement on the continent, partnerships with other African institutions, research excellence, and student success stories.  The UFS invites all members of its community to contribute thought-provoking pieces to this virtual celebration of Africa Month. Selected contributions will be presented on the university's website and social media.

Among other formats, contributions may take the format of

  • recorded performing art performances (e.g., solo music or poetry);
  • virtual visual art presentations;
  • written poetry;
  • songs;
  • short thought/opinion pieces, which can also be published in mainstream media; or
  • topical academic writings.

Please share a brief written proposal explaining your planned contribution by 30 April 2021. The proposal should not exceed 300 words and should be emailed to Cornelius Hagenmeier (hagenmeiercca@ufs.ac.za) or Prof Colin Chasi (ChasiCT@ufs.ac.za).

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
