Taking the lead to positively impact
Attending the graduation ceremony in the short learning programme: Teacher Professional Development for Digital Mobile Learning, and Entrepreneurship for SMMEs, were, from the left: Lintle Nthati Radikgomo, Thabile Sylvia Masangane, and André Uys from the Flavius Mareka College in Sasolburg, and Thandeka Mosholi from the UFS.

The Department of Social Responsibility, Enterprise and Community Engagement on the South Campus recently hosted a ceremony for students in the short learning programme: Teacher Professional Development for Digital Mobile Learning, and Entrepreneurship for SMMEs.

According to Thakane Nteko from the Social Responsibility Projects (SRP), 40 of the 66 students enrolled for the qualification in lecture development completed it, together with the 10 students who registered for the entrepreneurship programme. The students are mainly university and TVET (Technical and Vocational Education and Training) lecturers and self-employed youth.

She says the department aims to enhance teaching and learning in the Free State, be it for school learners, schoolteachers, TVET college lecturers, or the youth. Key in this initiative is the UFS, in partnership with Sector Education and Training Authorities (SETAs) and other organisations involved in community development, to make a positive difference in communities where there is a need.

Addressing social injustices
Positively impacting the youth of South Africa is of critical importance to the UFS. “Creating opportunities and growth through leading, learning, and teaching, is not only valid for the young intellectuals who have the chance to qualify themselves through tertiary studies. It is also applicable to the disadvantaged communities exposed to poor education. The UFS SRP serve as the vehicle to address this social injustice,” states Thandeka Mosholi, Head of the Department of Social Responsibility, Enterprise and Community Engagement.

She trusts that Social Responsibility Projects has established itself as a supporter of disadvantaged communities by responding to the call to positively impact the future of South African youth. “Our passion resonates with those who desire to open opportunities and bring purpose to gifted learners born in circumstances they did not choose, by being leaders in school change,” she says.

Destined for greatness
Delivering messages of encouragement at the event was KB Lebusho, CEO of the Free State Chamber of Commerce and Industry. Addressing the group of entrepreneurs, lecturers, and teachers, he told them that they are destined for greatness. “But until you believe in yourself, things will not change for you. It is important that you have clarity about your dreams and goals.”

Advocate Shirly Hyland, Director: Kovsie Phahamisa Academy, also left the students with a message of support. “By paying education forward, we can change the world. The power to touch the lives around you, lies in your hands. Enjoy taking the knowledge you have learned into your communities,” she said.

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.
