The COVID-19 pandemic has created profound disruptions in our economy and society.  Due to the challenges of this pandemic, most universities have decided to move from face-to-face classes to online teaching (more accurately defined as emergency remote teaching and learning) so as to complete the 2020 academic year, and to prevent the spread of the virus.

Online learning vs emergency teaching and learning
Online learning is the result of careful instructional design and planning, using a systematic model for design and development.  With remote emergency teaching and learning, this careful design process is absent.  Careful planning for online learning includes not just identifying the content to be covered, but also how to support the type of interactions that are important to the learning process.  Planning, preparation, and development time for a fully online university course typically takes six to nine months before the course is delivered.

Emergency teaching and learning is a temporary shift of instructional delivery to an alternative delivery mode due to crisis conditions.  Hence, one cannot equate emergency remote teaching and learning with online learning, nor should one compare emergency remote teaching and learning with face-to-face teaching. What is crucial is the quality of the mode of delivery, and although assessment methodologies will differ between face-to-face teaching and remote teaching and learning, the quality of the learning outcomes should be comparable.

Funding to universities 
The financial model used in a South African (residential) university consists of three main income sources: (i) the state or government through a subsidy (the so-called ‘block grant’), (ii) tuition fees, and (iii) third-stream income (which is mainly a cost-recovery component from contract research, donations, and interest on university investments). The National Student Financial Aid Scheme (NSFAS) contributes to the tuition fees through a Department of Higher Education, Science and Innovation Bursary Scheme, providing fully subsidised free higher education and training for poor and working-class South Africans (recipients will typically be students from households with a combined income less than R350 k per annum).  

The negative impact of COVID-19 on the income drivers of the university can, and probably will, be severe.  Although the subsidy from the state or government can be ‘protected’ for a cycle of two to three years through the National Treasury, the pressure on income derived from tuition fees (that component which is not funded through NSFAS) will be increasing, as households would have been affected by the nationwide lockdown and with the economy in deep recession, a significant number of jobs would have been lost. The economic downturn, due to both COVID19 and a sovereign downgrade by all rating agencies, has already negatively impacted local financial markets as well as the global economy. The multiplier effect of this would be that the value of investments and endowments decreases (at the time of writing the JSE was still 20% down compared to the previous year), and philanthropic organisations and foundations will most probably reduce or even terminate ‘givings’ to universities.

Industry, private sector, and commerce will re-assess their funding to universities, whether for research or bursary support.  Overall, it is possible that the income sources for universities can be affected negatively in the short term, but it will definitely have longer-term implications on the financial sustainability of universities.  In this regard, it would be important for universities to perform scenario planning on the long-term impact of COVID-19 on the financial position of the university, and to adjust their strategic plans accordingly.

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.
