Prof Liezel Lues, Professor in the Department of Public Administration and Management at the University of the Free State (UFS), has been elected as the President of the International Association of Schools and Institutes of Administration (IASIA)

The election took place on 14 October 2025 in Mexico City during the IASIA Board of Management meeting, where Prof Lues received an overwhelming 22 out of 25 votes. Describing her appointment as the pinnacle of her public service career, she reflected.

“It is a moment where hard work, dedication, and unwavering focus have truly converged, and I am deeply grateful to all those who have supported my growth and opened doors along the way.”   

Prof Lues, whose term will run until 2028, was nominated by former IASIA President Dr Najat Zarrouk and endorsed by Prof Ing. Juraj Nemec, Chairperson of the International Commission on Accreditation of Public Administration (ICAPA). 

 

Leading global collaboration in public administration 

As IASIA President, Prof Lues will provide leadership and strategic direction for the association's affairs, overseeing 127 international organisations across 56 countries. Her responsibilities include appointing - subject to the approval of the incoming Board of Management - seven Vice-Presidents representing each global region: Africa, Latin America and the Caribbean, the Middle East, Asia, Europe, North America, and Australia. 

In addition to these duties, she will be travelling extensively to strengthen global partnerships and advance IASIA’s mission of promoting excellence in public administration education and practice. 

 

A vision for a forward-looking IASIA

Prof Lues shared that her motivation to accept this leadership role stems from a desire to contribute strategically to global collaboration and research - particularly in empowering women in academia and public service.

“As a woman in academia and leadership, I was motivated by the need to model representation and inspire others to step into leadership spaces traditionally dominated by men,’’ she explained.  

Looking ahead, she envisions steering IASIA towards a more agile, forward-looking institution. Her priorities for the next three years include: 

  • Promoting and maintaining a collegial and collaborative organisational culture;
  • Embracing digital transformation and innovation;
  • Fostering cross-disciplinary, impactful research; and
  • Investing in sustainable institutional development and rehabilitation strategies. 

Drawing from her extensive experience - first in government and later in academia - Prof Lues expressed confidence in her ability to lead the association into a new era.  

“I am confident that my vision will build on the association's previous successes and elevate it to new horizons in the coming terms,” she said.

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.
