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.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
