Entrepreneurship Intravarsity
Audience members listening attentively to the presentations at the Entrepreneurship Inter-varsity on the Bloemfontein Campus.

The UFS continuously creates opportunities for students to develop and explore platforms where they can showcase their talents and share their innovative concepts. In the light of this, it is important for the institution to become a preferred academic knowledge partner that can conceptualise, develop, and successfully commercialise research activities, and through this foster an innovative and entrepreneurial culture that aligns to its Integrated Transformation Plan.

This is why opportunities such as the Entrepreneurship Intervarsity Competition are so important, since it encourages students to demonstrate their entrepreneurial talent, and through this connect with investors and industry leaders to start up a business.

The competition

Student entrepreneurs across the 26 public universities in South Africa were invited to submit their innovative ideas as part of a competition supported by Entrepreneurship Development in Higher Education (EDHE), in collaboration with the Allan Gray Orbis Foundation. The opportunities created through this initiative are twofold:

     1. For student entrepreneurs to present their innovative ideas and businesses. 
     2. For universities to demonstrate their entrepreneurial talent and the ways in which              they support and grow the next generation of business leaders.

The competition takes place in five stages. The process started with each student submitting their short videos and applications on the official competition site. Each institution also had the opportunity to select student entrepreneurs to take part in the competition. Fifteen students pitched their ideas during internal rounds at the UFS on 30 May 2019. Of these students, four were selected to represent the UFS at the regional rounds of the Entrepreneurship Intervarsity, where the finalists will be chosen. 

The students were judged in four categories:

Category 1: Innovative Ideas
Category 2: Tech Businesses (existing businesses, formal or informal, undergrad or postgrad)
Category 3: Social Impact Businesses (existing businesses, formal or informal, undergrad or postgrad)
Category 4: General (existing businesses, formal or informal, undergrad or postgrad)

The following UFS entrants were selected to take part in the regional finals: 
Christopher Rothman for his liquid yeast culture that can be used in the fermentation of beer. 
Driaan-Lou Kemp for his patented water-saving device. 
Grace Mthembu for her electricity-saving system.
Martin Clarke for his idea to use drone technology for the mining industry

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.
