Braille Signage
Big on Braille: Members of the Kovsie community who are living with visual impairments can now access directions through the new braille system.

The University of the Free State (UFS) commemorate World Sight Day, which is celebrated annually on the second Thursday of October. The day has been set aside and aimed at drawing attention to blindness and vision. This was originally initiated by the #SightFirstCampaign of the Lions Club International Foundation in 2000. 
The university aims to contribute to the development and social justice of all students through the production of globally competitive graduates. Thus, the development and implementation of co-curricular programmes, activities, services, and mutual infrastructure will allow for humanising daily lived experiences among students, which are essential for universal access, student academic success, social behaviour, engagement, and an inclusive institutional culture.

With this in mind, the university rolled out a capital project that included the construction of tactile pathways with braille indicators on the pathways, designed to support and caution pedestrians who are blind or visually impaired. The indicators are universally accessible, because it includes Braille and text. The text then gives indications to new students who are also struggling to find their way around campus.

A UFS Bachelor of Social Sciences student who dreams of becoming a social worker, Tshegofatso Nkatlholang, who was born partially blind, but is now completely blind is motivated by the prospect of living a life where she has the ability to help the less fortunate. Her opinion of the construction and implementation of the new tactile pathways on the UFS Bloemfontein Campus is that they are extremely helpful. She went on to say, “That is my road, and I am grateful for a university that strives to operate an inclusive infrastructural environment where I don’t feel sidelined.”
Kovsie student Keamogetswe Mbele was born partially blind with very low vision, eventually losing her eyesight. She explained that she had no knowledge of the newly built braille indicators on the tactile pathways, but that she felt appreciative of the university’s initiative to constitute an inclusive academic and infrastructural environment for all students on campus. Motivated by her personal goals of independence and financial freedom, ‘Kamo’, as her peers refer to her, is determined to live a prosperous academic life throughout the course of her studies at the UFS.

According to Mookgo Moloi, a Kovsie student who was not born blind but gradually lost her sight at the age of 15, said, “Life on campus is very caring”. She reflected on the opportunities, as well as the technical and emotional support that the Center for Universal Access and Disability Support (CUADS) has provided her, which has made her academic career a lot easier, and more advantageous for her to graduate. 
CUADS further strives to facilitate, create opportunities, and enhance students’ understanding of multiple intersections and ways of being that are consistent with human rights and the principles of social justice.

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.
