The African continent is known for endless wars, extreme poverty, under-development, and highly contested borders left by the legacy of colonialism. Low levels of literacy among young people and adults remain a concern in many African states. African universities are slowly beginning to play a significant role in contributing to national innovation systems that seek to change the socio-economic and other fortunes of many poor and marginalised Africans. 

The African continent celebrates the 57th anniversary of the founding of the Organisation of African Unity (OAU), and the relevance of the current African Union (AU) in the fight against socio-economic challenges caused by COVID-19 on the continent. The fear faced by most African countries emanates from inadequate healthcare systems and facilities. The debate on the opening of schools and institutions of higher learning is passed around like a soccer ball, as countries are aware that they lack the capacity to accommodate a surge of COVID-19 infections.

The African higher education and research sector is struggling to adapt. Will they be able to play a significant role towards finding a vaccine, producing new knowledge or research from African indigenous plants?  To be factual, in many ways this is not likely to happen, as most of the higher education institutions struggle with internet connectivity and high data costs. Many books and journals in libraries remain inaccessible, and most will only later record how developed countries moved to online teaching and learning with great success or failure.   All this will happen under the noses of illiterate Africans who rightly expect their higher education and research institutions to contribute towards finding immediate responses to the COVID-19 pandemic threat.

Most public and academic libraries remain closed and there is no word and contribution from highly decorated professionals towards sustaining reading habits and availing relevant materials for research towards finding a vaccine. There is no co-ordinated plan from library ministries and or library lobby groups. This is the context in which Africa Month 2020 is celebrated. It will be remembered as the year in which the promotion of reading and the opening of schools took a beating.

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.
