Human Settlements Conference
Attending the first National Student Conference for Human Settlement students were, from the left: Dr Anita Venter, Lecturer in the Centre for Development Support; Phelani Mkhize, master’s student in Urban and Regional Planning; Prof Maléne Campbell, Head of the Department of Urban and Regional Planning at the UFS; and Nhlakampho Mahlalela, also a master’s student in Urban and Regional Planning.

“This invitation by the University of the Free State (UFS) comes at a critical moment when we begin to roll up our sleeves in an attempt to transform the lives of our people, and in efforts to modernise our cities and towns to attain sustainable livelihoods.” This was the words of the MEC for Public Works, Infrastructure and Human Settlements, Tshidi Koloi, on attending the first National Student Conference for Human Settlement. 

“The urban population of the world has grown rapidly – from 751 million in 1950 to 8 billion in 2018. How do we plan for rapid urbanisation?” Koloi asked. 

“We turn to the academic world for continuous research in various fields related to the development of human settlements. The role of the university and of this department cannot be overestimated. Clearly, we need to forge partnerships where our department can benefit from ongoing research towards the improvement of its value chain and programmes. In return, government could offer bursaries and internship opportunities for students.”

Integrate communities

More than 130 students from the Nelson Mandela University, the UUniversity of KwaZulu-Natal, the University of the Witwatersrand, and the UFS attended the conference to gain a better understanding of the challenges, policies, and practices of human settlements. The conference also allowed students the opportunity to not only engage with key members of government, but also with each other and delegates from the private sector.

Head of the Department of Human Settlements, Tim Mokhesi, said his department’s objective with housing for the future is to integrate communities; not to separate them because they are poor. If we separate communities, our next struggle will be a class struggle. 

“South Africa is in a crisis in terms of human settlement. In the past years, there was an exponential growth in informal settlements – 300 to 3 000 (with 143 in the Free State); the housing budget shrank, and local authorities do not have the capacity to deal with informal settlements. Can the few of us make a sufficient and significant contribution? Seeing your commitment as students is what gives us hope for a better future for all,” Thomas Stewart, Lecturer in the UFS Department of Urban and Regional Planning, said.

Innovative and inclusive re-housing

Students experienced two fieldtrips, one to the Hillside View Development Project, where the focus was on mixed housing. This project is part of the Mangaung Metro Municipality’s five-year integrated human settlements plan. According to developer Freddie Kenney, the project needs to be a development model for South Africa to change the picture of social housing. 

The second site visited was the Innovative Housing Building Project: Qala Phelang Tala, where peo-ple are trained to build their own houses. “It is a very easy process,” said Dr Anita Venter, Lecturer in the Centre for Development Support, who is lecturing Human Settlements Theory in the Department of Urban and Regional Planning. Since 2013, she was involved in the building of five houses. 

The latest building project at the Meraka Cultural Village in Roodewal, outside Bloemfontein, is a stu-dent-led project where they learn to develop a basic shelter suitable for survival in a future, post-natural, and climate-crisis world that will become between 2 and 4 degrees Celsius warmer within the next century. “It is important for people to build in climate-friendly ways,” Dr Venter said. 

She continues: “The project seeks to also renew, restore, and revitalise communities.” Sebabatso Mofama, who now helps with training, built this house similar to the one where she comes from in the Eastern Cape. “It is where I feel at home,” she said. 

The human aspect 

Dean of Student Affairs,Pura Mgolombane, touched on the human aspect of human settlements. “We first need to see the human in human settlements. ‘Yebo’, meaning I see you. See the human and develop quality houses.”

The event coincided with the launch of the new Bachelor of Spatial Planning Honours with specialisation in Human Settlements. The first two students graduated in April this year.

Research helps farmers save with irrigation

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.
