Academic Leadership Programme
The new cohort of the Academic Leadership Programme.

Educational leaders serve a significant administrative, management, and leadership function in higher education. A departmental chair’s role differs fundamentally from other leadership contexts, based on the momentous transition from being an academic by profession to providing leadership at departmental level.
The Academic Leadership Programme (APL) was launched by the University of the Free State (UFS) Centre for Teaching and Learning (CTL) to equip academics for various managerial positions. Faculty deans propose candidates for this programme; the second cohort has been chosen as the first is nearing completion. 
The first workshop commenced with an engagement with the Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, and the Vice-Rector: Academic, Dr Engela van Staden, who both shared strategic academic leadership perspectives during the orientation and welcoming of the APL. 
Such reflections highlighted the expectations of being an educator, the complexity, and the critical role of departmental chairs within higher education institutions. Academic leaders are thus expected to establish firm leadership within their departments, facilitate intellectual development, manage administrative duties, and strive toward resilient learning and teaching environments. 
“The position of departmental chairs remains critical for any higher education institution, as they provide leadership in advancing the discipline, teaching students, producing quality graduates, and serving the professional community,” said Prof Francois Strydom, Senior Director: Centre for Teaching and Learning.
Research confirms that most academics succeed in these roles without formal leadership training, yet the expectation of developing or having certain leadership qualities or management competencies must fulfil the various functions of such a position.

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.
