Dr Millard Arnold, UFS Council Member and Senior Consultant at Bowman Gilfillan.

Dr Millard Arnold, Council Member of the University of the Free State (UFS) and Senior Consultant at Bowman Gilfillan, recently contributed to a noteworthy book on leadership and a book on responsive universities. His experience as a journalist and later as a seasoned leader and keynote speaker positioned him well to participate in the book: The Book Every Upcoming, New, and Seasoned Leader Needs to Read – Lessons From Leading Business Minds and Thought Leaders. 

From surviving to thriving

Incorporating collective leadership wisdom for both the leaders of tomorrow and the leaders of today, the book is full of lessons, insights, pep talks, advice, and direction for building your own style and approach to great leadership, and not to shy away from the ecstasy (and sometimes agony) of becoming a significant leader. Packed with the contributions of 48 authors, the book is the antidote to the lack of mentorship in the field. Authors include Brand Pretorius, Edwin Cameron, Marnus Broodryk, Nyimpini Mabunda, and Roze Phillips – to name a few. 

Giving problems to solutions

Dr Arnold’s contribution focuses on fishing out the valuable leadership principles from the sea of leaderships that we are drowning in. “I have found myself in positions of leadership and have had to develop a number of thoughts on leadership which have helped guide me in determining how best to lead,” he writes. This guided him to discover the true essence of leadership, which is problem solving. He asserts that “if there are no difficulties to overcome, no problems to resolve, the leadership is unnecessary”. Leadership has its genesis in problems, he believes. 

Effective leaders make things happen

Among the profound insights that Dr Arnold shares, he highlights the notion that great leaders must understand the problem and have the vision to see the solution. Inevitably, this necessitates the leader to take some risks and to persuade others to get on board. This is only possible if the leader has integrity and ultimately deliver on the promise made. He advises leaders to “ask good questions, listen to the answers, assess the reality, be empathic, and spend a great deal of time on self-reflection”.

Universities must remain relevant 

Dr Arnold also contributed a chapter titled, Poverty, Inequity and Decolonisation: Are Business Schools Responsive to the Challenge? in a book by Chris Brink, The Responsive University and the Crisis in South Africa. The book brings together contributions on the issue of responsiveness from several international university leaders. Dr Arnold’s chapter presents an overview of the impact of colonialism and capitalism on the African mind set and stresses how different South African business schools have responded to the task of being responsive to the challenges confronting the country. It argues that, if carefully managed, business schools can, and should be, vehicles to promote and facilitate positive and constructive change.

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.
