Noko Masalesa, Director of Protection Services, in conversation with students and stakeholders to plan a safe way forward.

Safety and security are human rights that constitute social justice. At the centre of the agenda at the University of the Free State’s (UFS) Social Justice Week held on the Bloemfontein Campus from 17-22 April 2019 were discussions about off-campus safety. Stakeholders agreed on an upgrade to security measures in order to ensure the success and wellbeing of the student population.

A call to students

Prof John Mubangizi, Dean of the Faculty of Law, in his capacity as representative of the UFS Rector and Vice-Chancellor, Prof Francis Petersen, expressed his view on institutions of higher learning no longer functioning as ivory towers. “For any initiative to succeed, collaboration is necessary between key roleplayers,” he said.

He aptly pointed out that: “We cannot underscore the importance of safety and security, not only for the university but also for the communities around us. What the university does benefits the community and vice versa. I pledge the university’s commitment to play a leading part to ensure that the collaboration works,” said Prof Mubangizi.

Beefing up security: Who is involved?

In view of the collaborative effort Prof Mubangizi alluded to, the engagement was twofold. First was the roundtable discussion facilitated by Protection Services which then escalated into a public dialogue where students had the opportunity to interact with external delegates.

The South African Police Services, Community Police Forum, Private Security, Mangaung Metropolitan Municipality, Provincial Commissioner, and Deputy Minister of Police were well represented in this critical conversation. Internally, members of Protection Services, Housing and Residence Affairs, Student Affairs, Institute for Social Justice and Reconciliation, Student Representative Council, and the Department of Criminology heard the plight of off-campus safety faced by students.

Changes in the horizon

The discussions culminated with recommendations which will see the future of student safety take a different direction. According to Skhululekile Luwaca, former SRC president, these include “the municipality’s commitment to immediately address issues such as street lights and enforcing by-laws, ensuring an integrated accreditation system, and drafting a policy for off-campus accommodation, running more crime awareness campaigns, and giving police patrols more visibility.”

In addition to resolving to set up a student safety forum with all the stakeholders, the Mangaung Metropolitan Municipality has invited the UFS to join Reclaim the City – a safety forum where practical solutions to crime are devised and implemented on a weekly basis.

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.
