Social Work students at the UFS are working with the relevant stakeholders in an Engaged Teaching and Learning service-learning project to promote and respect children’s rights.

The protection of children’s rights is the principal achievement on the Sustainable Development Goals (SDGs) 2030 Agenda. Emphasis has always been on the promotion and respect of children’s rights. Since the SDGs are grounded in a child rights-based approach, the University of the Free State (UFS) Social Work students – by engaging in a multi-disciplinary methodology – involve all the relevant stakeholders in their Engaged Teaching and Learning service-learning module project. 

The social partners, which included the South African Police Service (Child Protection Unit), the Department of Social Development, the Department of Home Affairs, the Department of Health, faith-based organisations, and other children’s advocacy agents, were involved from inception until the apex launch of the project. 

Access to basic human rights

In their exit level, fourth-year Social Work students participate in community work practicums, which incorporates the theoretical development process in adherence to the objectives of their community work. The initial phase of the project involved the situation analysis exercise, which the students implemented through collaboration with the Rekgonne Primary School action committee. 

The outcome of the survey indicated that some learners were exposed to physical and sexual abuse. It was also found that they did not have access to basic human rights such as education, health care, and social grants due to the absence of the required legal documents. From the interactive discussions that took place during the launch, it emerged that some children do not have birth certificates required for school registration and access to social grants. 

Through the students’ community project, a platform was created where important skills and information could be shared among all important role players (who are in different professions and guardians of children’s human rights). It is believed that since learners are spending more hours in school, educators would be the primary detectors to notice signs of negligence and potentially adverse circumstances among their learners.

Role players collaborate to make a difference

Through the scholarship of engagement, students succeeded in engaging with the community to attend to societal challenges (violated children’s rights). In order to realise the outcome of the project, continuous collaboration among all role players must be sustained. All parties adopted a resolution to create safe environments both at school and at home by supporting families and caregivers.

Government partners that participated were determined to strengthen protection systems and improve child welfare, reinforcing the implementation of the Children’s Act 38 of 2005.  Educators were empowered and supported in the mandate of the Quality Learning and Teaching Campaign (QLTC). This is an initiative that involves stakeholders in improving the quality of education for all children and addresses issues of safety and well-being for all children.

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.
