We are indeed privileged to have this paper from Prof Toyin Falola to include in our celebrations of Africa Day. Toyin Falola is a world-renowned African. A scholar of African history and African studies, he holds the Jacob and Frances Sanger Mossiker Chair in the Humanities at the University of Texas, Austin. He has published, as author or editor, more than 100 scholarly books on topics ranging from diaspora, migration, empire and globalization to intellectual history, international relations, religion and culture. He has been awarded seven honorary doctorates and has received, among many other awards, the Distinguished Africanist Award from the African Studies Association, the Ibadan Foundation Award for Professional Excellence in Scholarship and the Cheikh Anta Diop Award for Excellence in African Studies. He served as Vice President of UNESCO’s International Scientific Committee, Slave Route Project from 2011 – 2015 and currently is a member of the Carnegie African Diaspora Fellows Programme and the International Committee of the Thabo Mbeki African Leadership Institute at UNISA.

In this wide-ranging paper, originally presented as keynote address at the Visions of African Unity (1930s – 2018) conference at the University of the Free State, Prof Falola begins with a tour of the intellectual history of ideas of African Continentalism (Pan-Africanism / African Unity), from Henry Sylvester Williams, through WEB du Bois, Marcus Garvey, George Padmore and Julius Nyerere, to Kwame Nkrumah. He then describes the current institutional landscape of African unity and present-day intellectual versions of African Continentalism. Asking, and answering the question ‘Why must Africa unite?’, he then proceeds, on the basis of a consideration of more contemporary intellectual versions of African continentalism such as Black Consciousness, Black Nationalism, Afropolitanism, and now Afrofuturism (which he depicts as ‘ideological dispensations of true African cultural recovery and re-orientation’), to propose a disaggregated approach to contemporary African unity that is not fixated on global-Northern models. This means that unity should (re)start small, working territorially from regional units toward a continental unit, on the one hand; and on the other, seeking unity and cooperation around discrete substantive themes, from the more obvious and traditional, such as economic policy, global politics and a reformed unified political and military system, to the less, such as common educational policy, synergizing science and technology with African culture(s) and language, culture and literary exchange.

We thank him for the gift.

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
