4IR Prof Marwala

A computer programmed to play poker and learning by itself how to bluff; an algorithm that predicts whether two countries will ever go to war; machines that detect epilepsy with almost flawless accuracy these are some of the groundbreaking abilities brought about by technologies associated with the Fourth Industrial Revolution (4IR).

Addressing the first UFS public event to enhance 4IR awareness, Professor Tshilidzi Marwala, Vice-Chancellor and Principal of the University of Johannesburg, briefed staff, interested parties and members of the media about recent 4IR developments and their implications.

Prof Marwala is currently a thought leader on the impact of the 4IR on higher education in South Africa as well as the Deputy Chairperson of the national commission appointed by the president to formulate 4IR strategies for South Africa.

Industrial revolution history

He recapped how, during the first industrial revolution, people started to understand how nature worked, ultimately leading to the development of the steam engine.
The second industrial revolution was marked by the development of electromagnetism which led to electrification and mass production, while the third produced computerisation and a rise in digital technology. 

The fourth industrial revolution is characterised by a fusion of technologies that blur the lines between cyber, physical and biological systems. This has led to rapid advances in fields such as artificial intelligence, quantum computing and 3D printing.


Artificial intelligence

Prof Marwala pointed out that, although fears were rife of machines taking over people’s jobs, the flipside of the coin was that dangerous jobs such as fire rescue operations could be carried out by machines without endangering lives.

Artificial intelligence can be employed to prevent bridge and building collapses by monitoring the condition of structures. It can also be used in credit scoring, where machines search for and analyse all the available data on a credit applicant, without having to rely only on the (sometimes fraudulent) information supplied by the credit seeker. 

He emphasised the great need to develop algorithms applicable to our continent, such as translating software that makes provision for the clicks in languages like isiXhosa, and facial recognition software that incorporates data collected in African countries. 


Is Africa ready? 

Responding to a question from an audience member, Prof Marwala indicated that Africa was certainly not ready for the 4IR when it came to the content of teaching curricula and infrastructure.

“As universities, we should not sit back and wait for change. We have the responsibility to lead our societies to have the same experiences as elsewhere in the world,” he concluded.

Groundwater management vital for groundwater sustainability

An interest in groundwater resource management ignited the spark for a PhD research thesis by Dr Yolanda Kotzé, Affiliated Researcher in the Institute for Groundwater Studies (IGS) at the University of the Free State (UFS).

Her PhD research thesis titled, A Framework for Groundwater Use Authorisations as Part of Groundwater Governance in Water Scarce Areas within South Africa, was the result of her interest in groundwater resource management. Dr Kotzé identified the agricultural sector as one of the major water users, and a decision was made to conduct research within this sector.  

Research funded by Institute for Groundwater Studies
Groundwater is water found underground in cracks and spaces in soil, sand, and rocks. It is stored in, and moves slowly through geological formations of soil, sand, and rocks (aquifers). The National Department of Water and Sanitation was indirectly the client for this research. The research project was funded by the IGS. Given the current drought, effective groundwater resource management can be achieved within all sectors through sustainable abstraction and use without over-abstraction.

“Groundwater can be effectively managed
in the agricultural sector by sustainable use,
monitoring the quantity of groundwater use,
and measuring groundwater levels,”
said Dr Kotzé.

Research addresses improvement of groundwater management
Her promotor, mentor, teacher, and friend, the late Prof Gerrit van Tonder, introduced her to the field of Geohydrology, and especially to groundwater resource management. “With my research, I made a significant contribution to the improvement of groundwater governance and groundwater resource management, as well as to the handling of groundwater use authorisations for irrigation purposes in South Africa,” said Dr Kotzé. With this significant contribution, she attempts to address the phenomenon of poor groundwater allocation and groundwater resource management by means of a framework. The development of this framework has shown the value of action research in an attempt to find a solution to a problem. “Groundwater can be effectively managed in the agricultural sector by sustainable use, monitoring the quantity of groundwater use, and measuring groundwater levels,” said Dr Kotzé.

The methodology of the research consisted primarily of action research, which has a five-phase cyclical process. The research was Dr Kotzé’s application for a PhD in Geohydrology at the UFS in 2012. The research was completed in 2015.
