Prof Edilegnaw Wale Zegeye, who has joined the UFS Department of Agricultural Economics, believes university education is not just a requirement for learners to receive a certificate; it is a means to change their character, capacity, and reasoning.

Edilegnaw Wale Zegeye joined the Department of Agricultural Economics at the University of the Free State (UFS) as Professor of Agricultural Development Economics and Policy on 1 October 2020.

True to his belief that life is like riding a bicycle – to keep your balance, you must keep moving (Albert Einstein) – Prof Zegeye is not planning to wait for life to happen. He says that he is looking forward to engaging with his colleagues in the department regarding new challenges in the areas of teaching, research, and community engagement.

Teaching and learning

Prof Zegeye believes COVID-19 has made it necessary to come up with new ways and means of realising effective teaching and learning. He is convinced that even though online teaching has suddenly become the norm, many universities, including the UFS, will in future have to adopt some form of a hybrid, merging online with contact classes. 

“Given the uncharted territories we have to navigate, I foresee operational and content-related challenges in this area,” he says. 

These challenges, he believes, will require disrupting the status quo courageously, without neglecting the implications for teaching and learning outcomes.

Prof Zegeye is of the opinion that university education is not just a requirement for learners to receive a certificate. “It is a means to change their character, capacity, and reasoning. It is not about learning facts but enabling learners to think critically.”

His goal for his students is to enable them to master the subject matter content, not just memorise lecture notes to pass examinations. “Students should not expect everything from us, as teaching and learning is a two-way process. It is not a transfer of knowledge from a lecturer to students,” he says.

According to Prof Zegeye, success in teaching and learning is the outcome of the collective engagement of the lecturer, students, and the subject matter. He believes that was why Benjamin Franklin once said: “Tell me and I forget. Teach me and I remember. Involve me and I learn.”

Research

“In relation to research, the biggest challenge I anticipate is in terms of linking evidence-based knowledge with policy, implementation, and impact on the ground.”

He says the biggest challenge was to ensure that the knowledge generated is taken up by the relevant organisations and authorities in order to address the development-policy problem being examined. “This would, among other things, call for fixing the knowledge-action gap, addressing conflicts of interest, and engaging all the relevant stakeholders along, what I would call, the Research-Knowledge-Policy-Impact Nexus,” says Prof Zegeye. 

Prof Zegeye has more than twenty years of experience with higher education institutions, including the positions of Senior Lecturer, Associate Professor, Professor, and Honorary Professor (current appointment) in Agricultural Economics at the University of KwaZulu-Natal (UKZN). 

Although he spent several years at UKZN, he started his academic career at Alemaya University in Ethiopia. It was also at this university that he received a BSc in Agricultural Economics. He continued with his studies and obtained a master’s degree in Agricultural Development Economics from Wageningen University (the Netherlands), and later a doctoral degree in Agricultural and Natural Resources Economics from the University of Bonn. He obtained all degrees with distinction. 

Prof Zegeye has also gained valuable experience from working as an economist on the Genetic Resources Policy Initiative (GRPI) project of Bioversity International in Kenya. He has also been a consultant to, among others, the International Food Policy Research Institute and the International Livestock Research Institute. 

“Building on my experiences, I strongly believe that there is always room for improvement in whatever we do. If we all agree with that philosophy, all of us have a unique contribution to make to achieve excellence in what we do. There is a need to remind ourselves that excellence is not a destination; it is a journey that all of us need to take as a collective responsibility,” states Prof Zegeye. 

Published articles

To date, he has published more than 80 papers on water use in smallholder agriculture, agrobiodiversity conservation and technology adoption on smallholder farms, agricultural development policy, and impact assessment of development projects/programmes/policies. Prof Zegeye is also associate editor of the International Journal of Climate Change Strategies and Management and serves as a reviewer for various internationally accredited journals.

UFS study on cell development in top international science journal
2008-09-16

A study from the University of the Free State (UFS) on how the change in the packaging of DNA with cell development influenced the expression of genes, will be published in this week’s early edition of the prestigious international, peer-reviewed science journal, the Proceeding of the National Academy of Sciences of the USA (PNAS).

The PNAS journal has an impact factor of 10, which means that studies published in the journal are, on average, referred to by ten other scientific studies in a two year period. The South African Journal of Science, by comparison, has an impact factor of 0.7.

The UFS study, funded by the Wellcome Trust and the National Research Foundation (NRF), looked at how the change in the packaging of DNA with cell development influenced the expression of genes. It is very relevant to research on stem cells, an area of medicine that studies the possible use of undifferentiated cells to replace damaged tissue.

Prof. Hugh Patterton, of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, who led the study, said: "We are extremely proud of this study. It was conceived in South Africa, it was performed in South Africa, the data were analysed in South Africa, and it was published from South Africa."

When a gene is expressed, the information encoded in the gene is used to manufacture a specific protein. In eukaryotes, which include humans, there is approximately 1m of DNA, containing the genes, in every cell. This length of DNA has to fit into a cell nucleus with a diameter of only about 10 micrometer. In order to fit the DNA into such a small volume, eukaryotic cells wrap their DNA onto successive protein balls, termed nucleosomes. Strings of nucleosomes, resembling a bead of pearls, is folded into a helix to form a chromatin fiber. The study from the UFS investigated how the binding of a specific protein, termed a linker histone, that binds to the length of DNA between nucleosomes, influenced the formation of the chromatin fiber and also the activity of genes.

"We found that the linker histone bound to chromatin in yeast, which we use as a model eukaryote, under conditions where virtually all the genes in the organism were inactive. It was widely believed that the binding of the linker histone caused the inactivation of genes. We studied the relationship between the amount of linker histone bound in the vicinity of each gene and the expression of that gene for all the genes in yeast, using genomic techniques. We made the surprising discovery that even through the linker histone preferentially bound to genes under conditions where the genes were shut off, this inactivation of genes was not caused by the binding of the linker histone and folding of the chromatin,” said Prof. Patterton.

He said: “Instead our data strongly suggested that the observed anti-correlation was due to the movement of enzymes along the DNA molecule, involved in processing the information in genes for the eventual manufacture of proteins. This movement of enzymes displaced the linker histones from the DNA. This finding now requires a rethink on aspects of how packaging of DNA influences gene activity."

Prof. Patterton said that his research group, using the Facility for Genomics and Proteomics as well as the Bioinformatics Node at the UFS, was currently busy with follow-up studies to understand how other proteins in nucleosomes affected the activities of genes, as well as with projects to understand how chemicals found in red wine and in green tea extended lifespan. "We are certainly having a marvelous time trying to understand the fundamental mechanisms of life, and the UFS is an exciting place to be if one was interested in studying life at the level of molecules," he said.
