SK Luwaca at UFS Safety Summit for off-campus students
Sikhululekile Luwaca, leader of the UFS Safety Champions, addresses a delegation at the Higher Education Safety Summit from 18-19 October 2019 at the Bloemfontein Campus.

A meeting of minds over student safety recently took place at Kovsies. The Higher Education Safety Summit saw a cohort of 165 students from the University of the Free State (UFS), Central University of Technology and Sol Plaatje University, collaborating with the heads of Protection Services from the respective institutions to devise a safety blueprint specifically focusing on the off-campus environment.

“The rental tribunal came on board to assist with rental disputes between students and landlords, in addition to accreditation issues being discussed,” Sikhululekile Luwaca, former SRC President of the Bloemfontein Campus and leader of the UFS Safety Champions that form part of the Unit for Institutional Change and Social Justice.

Luwaca further said that the Mangaung Metropolitan Municipality also committed to assist the universities in addressing crime and enforcing by-laws. “A strategic safety plan was developed around spatialisation and zoning of student communes, developing a system that will assist universities to establish where students stay by using technology such as geographic information system (GIS),” he added.

What were the objectives of the summit?
Being the first of many to come, the summit set out clear objectives which all stakeholders have committed to work tirelessly to achieve, both in the short and long term.

The goals of the summit were threefold. Firstly, the intention was to build capacity between students and staff of all institutions involved to implement programmes by transferring the skills and knowledge between one another.

Secondly, the idea was to gather and consolidate input from the various higher-learning institutions and by so doing diversify the solutions. Thirdly, the purpose of the summit was to create an official platform where partners may consult on interventions that will ripple from the local, to the provincial and further to national level.

Andiswa Msomi, Spatialisation Group Leader and the Safety Champions’ administrator said she appreciated the shift in perspective that the summit brought. “The summit brought to my attention that sometimes we focus so deeply on one aspect of a problem that we end up not seeing alternative solutions. Due to active participants, new solutions came up, new ideas were brought forth and more importantly, we were able to get other institutions on board,” she said.

What are some of the tangible outcomes?
Going forward, an internal report which focuses on crime prevention measures will be presented to all UFS stakeholders. An external report, which will be submitted by the Safety Champions to the government in January 2020, is expected to be integrated into the Provincial Crime Prevention Strategy.

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.
