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.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
