Transformation at the university must be reflected in all dimensions of the institution, such as leadership, governance, and management, student backgrounds such as practical access and academic excellence, equity in staffing, institutional cultures, and inclusive teaching and learning. I acknowledge that this is not an easy task for universities, and that is why I would urge the student population to exercise patience on some of the matters they bring to the institution. However, they should also not be used by the university as a crutch in undertaking its obligation to transform and promote integration, non-discrimination, and inclusivity across all levels –  not only within the university, but also within the local space where the university finds itself, as we know the history of the institution. We have come a long way and there is still more to do, things to change, but we have to give credit where it is due. I still appeal to the institution to do more, because for some students it is the place that will give them the capability to fight poverty, to prosper, to influence change in society, and to change their lives as well as the lives of their families.

The redress of historical inequalities between historically white and historically black universities – it is a challenge for all universities, and we have come a long way to resolve this. With a new culture of students comes a new challenge, such as the funding challenges that poor and middle-income students are constantly facing. These are some of the recurring issues faced by students continually, requiring a solution that does not impoverish the poor even more. Universities must become spaces for transformation, rather than merely being transformed spaces. It is the transformative development through which students come to understand social justice properly, which certifies that students will go on to promote social justice in the wider society. While universities have long been sites of personal growth and transformation for their students, the impact of the transformative power of these places and the important transformational goal of generating graduates who are engaged citizens working for social justice must not be overlooked, particularly in the literature of transformation at the university.

Similarly, what is questioned by the students themselves is the relevance of what is taught at universities, how students are prepared through the knowledge and skills 'transmitted' to them for life in a South African context, and in what sense graduates are prepared to contribute to the advancement of society after the completion of their degrees. It cannot be that in this era we produce graduates who are job seekers, especially considering the status our country is in. This should be carefully considered in the development of the university’s curriculum and in its strategies.

It is only through an epistemic revolution in institutional culture that universities can become spaces that foster the development of civic-minded graduates. We cannot be relegated to just being students when it comes to the issues raised above if transformation is to take place effectively. Students must also understand that we cannot continue to do things as if it were 1976; we need to find other alternative mechanisms to voice our concerns and make an impact. At times change is not easy and it is not comfortable, but we are ready!

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.
