If all works out, Kovsie student Stephan Diedericks could change the face of the Mangaung Metropolitan Muncipality’s transportation facilities and save the city millions in maintenance costs while generating income.

The Masters Architecture graduate designed an innovative model titled An Interminable Living Machine: Humanizing and Re-appropriating the dormant Mangaung Intermodal Transport Facility (MITF) into a living, economic systems of change which won him the Corobrik Regional Student of the Year Award. The awards ceremony was hosted by the UFS Department of Architecture on 22 November 2019 at the Bloemfontein Campus.

A living machine

Re-appropriating the Bloemfontein taxi terminal located in the Central Business District (CBD) which has been non-operational for a few years would mean that the building sustained itself, and acted a power generator both environmentally and economically. 

Diedericks was inspired by the need to improve the quality of life for the people of City of Roses. “This course helped to broaden my perspective on the power of architecture and the social change that it can bring to people's lives,” he said.

An environmentally-friendly concept

According to the young architect, the facility would be water efficient. “Bloemspruit channels run underneath the proposed site and water will be filtered through biologically that will provide water to the entire site creating a self-sufficient living building with water at its heart.”

A thriving economic hub

Diedrick’s 220-page thesis details how the site of the intervention was once home to Bloemfontein’s first power station and that it is this concept of power generation that led him to place clients at the centre of the project as a catalyst for change.  

“The Small, Medium and Micro Enterprise Business (SMME) division of the Free State Department of Economic, Small Business Development, Tourism and Environmental Affairs (DESTEA) serves as the catalyst and a power generator that breaks open the solid mass of the MITF. Several subsystems, including aquaponics and SMME training, feed of the main catalyst and in turn provide resources in the form of food and business training to ground-floor users and micro-enterprise users onto latch onto over many decades of growth,” he explained.
 
A bright future ahead

"The only thing that we have and you don’t is experience,” said Petria Smit, a lecturer at the Department. “Some of your talent far exceeds ours.” During the awards ceremony, she said it was a privilege to work with students of such impressive calibre.

The awards, which were hosted for the 32nd year, are a way for the Department, in collaboration with Corobrik, to reward the talent of students. Diedericks said his win was a great honour and worth the many hours he had sacrificed for this course. Having bagged his master’s, Diedericks’s future plans are to work for the City of Bloemfontein as an architect or on an urban level when an opportunity arises.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
