The University of the Free State (UFS) has appointed Prof John Klaasen as Dean: Faculty of Theology and Religion from 1 April 2024. 

Prof Klaasen is Professor of Theology and has served two terms as Head of the Department of Religion and Theology at the University of the Western Cape. He also served as Professor in the Kjell Nordstokke Chair in Community Development at VID Specialized University in Norway and is Adjunct Professor at VID Specialized University. 

“With his vast experience and involvement in research projects – nationally as well as internationally – Prof Klaasen will make a significant contribution to the Faculty of Theology and Religion and the university in general. This will also be valuable in support of the university’s Vision 130, which is an expression of our strategic intent to position the institution towards 2034 when the UFS will be 130 years old,” says Prof Francis Petersen, Vice-Chancellor and Principal of the UFS.

As a practical theologian, the intersection between praxis and theory has occupied Prof Klaasen’s research for the past decade. He has researched and published extensively within theology, community development, and narrative. Aspects such as narrative, embedded knowledge, participation, reconciliation, and the non-rational tradition of knowledge are some of the areas that occupy his research outputs.

He is involved in numerous international research projects, which include a COST project with 17 European institutions, a project on reconciliation processes with institutions in Canada and Nordic countries, an international initiative on community development with various institutions in Europe, and a NORPART initiative with Norway and Malawi.

Community engaged scholarship forms a central part of his research and work at the intersection of religion and social justice. Prof Klaasen is involved in various community development projects, including homes for the aged, lay training, water issues, and lay theological education.

His teaching is situated within a socially just pedagogy, which puts the students at the centre of knowledge production. This innovative way of knowledge production intersects students, teachers, and the lecture room within a dynamic space of contextualisation.

“I am grateful for the opportunity to join such a prestigious institution and will endeavour to contribute to Vision 130 through commitment, innovation, trust, and ethical leadership – which represents the university’s commitment to be recognised by our peers and society as a top-tier university in South Africa, ranked among the best in the world,” says Prof Klaasen.

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.
