Prof Linus Franke delivered his inaugural lecture on the topic Contested Science for Sustainable Agriculture.

Conducting research on weed control for India at the Scottish Agricultural College in Scotland, studying soybean at the International Institute of Tropical Agriculture in Nigeria, and working with genetically modified crops at Agrosystems Research, Dienst Landbouwkundig Onderzoek (DLO) in Wageningen in the Netherlands, grain legumes in sub-Saharan Africa, and potatoes in South Africa. 

These are some of the agricultural practices that Prof Linus Franke, Academic Head of the Department of Soil, Crop and Climate Sciences at the University of the Free State (UFS), has seen and experienced in several countries, which contributed to his extensive knowledge on this matter.

More specifically, sustainable agriculture is his passion and the focus of his life’s work. In celebration of his academic career, this was also the topic of his inaugural lecture: Contested Science for Sustainable Agriculture, delivered on the Bloemfontein Campus on 4 May 2022.

With years of experience in the field, he reflected on sustainable agriculture, firstly stating that it would be good if we could have discussions on sustainable agriculture and the future of agriculture based on empirical evidence. “However, the reality is that ideology and a strong involvement of non-specialists is unavoidable,” he says.

Secondly, he adds, it would be a major improvement if we could move away from embracing universal principles for farming practices and forcing them into a local context. “It would be better if local contexts and aspirations could guide the way in which general production principles are applied.” Adding to that, he states the importance of measurements. “If you want to embrace the concept of sustainability, you must be able to measure it.” 

Solutions to environmental problems 

In his lecture, he took the audience back to years ago when he was doing his master’s research on organic farming systems, excited about organic agriculture as an approach that holds the promise of tackling major environmental problems in a radical manner. This bout of excitement about the prospects of organic agriculture was, however, short-lived. Fed up with the “dogmatic and anti-science attitude and the tribalism in the sector”, he saw his flirt with organic agriculture as youthful foolishness.

After spending years in India and Nigeria, Prof Franke produced reports on the sustainability and trade impacts of genetically modified crops. People in the organic and green movement, however, have expressed opposed views. “In their eyes, I was one of those short-sighted scientists unable to recognise the dangers of genetically modified (GM) crops.”

This made him wonder what drives these polarised discussions on GM crops and sustainable agriculture in general. “I learned that the strong and almost irrational position that the green movement has taken against GM crops and in favour of organic agriculture is merely a reflection of underlying emotions and preferences,” he says.

He explains two different lines of thinking about how to deal with the ecological challenges associated with agriculture, namely looking at nature to find solutions to environmental problems associated with agriculture, versus the idea that technology will come to our rescue. “The ecological problems we face in relation to agriculture are caused by modern farming technologies. Genetic modification is seen as an extension of the technologies that were responsible for the problems in the first place. To solve the problem, we need to look back at nature, learn from nature, and apply ecological principles to farming. You could argue that this view is rather unscientific and techno phobic. But believing that new technologies will come to recue us in the looming ecological crisis is equally based on a gut feeling, there are no guarantees that this will happen.”

Regenerative agriculture

Despite the strong position taken by the green movement in favour of organic agriculture, the organic movement became stagnant. “In Europe it represents only 5% of the total agricultural production and in South Africa it never really took off. GM crops have been relatively easily accepted here.”

GM crops and organic agriculture may not be major issues in South Africa, but regenerative agriculture has become a big topic and the discussion and dynamics around regenerative agriculture resemble those around organic agriculture.

"Over time, new approaches to agriculture have emerged, promising radical improvements in sustainability. Including conservation agriculture, holistic grazing, permaculture, and agro-forestry, these new approaches are grouped under the flag of regenerative farming and are attracting much attention. This has stimulated interest in using knowledge of ecological processes to improve agricultural production. 

“This is truly positive,” states Prof Franke. “It is great to see farmers in South Africa coming together and thinking about ways to apply some of these principles in their farming practices.”

Many of these approaches have proven their merits, but only under certain conditions. “Although many see regenerative farming approaches as globally applicable solutions to the big ecological challenges of today, it is important to take note of the context and the empirical evidence of the claimed benefits. Inspiration by nature does not necessarily lead to farming practices that are ecologically superior,” he says. 

Conservation agriculture, for instance, worked on large-scale mechanised crop farms in Australia and the Americas and it gained a firm foothold in the Western Cape. “But in Africa, including South Africa, conservation agriculture is widely promoted among smallholders, often with disappointing results,” he says.

Another challenge he addressed during his lecture, was that of expectations of regenerative agriculture being way beyond what farmers actually achieve. He found that large food corporations had announced major investments in regenerative agriculture, and by doing so, hoped to reduce their carbon footprint regarding production activities. The big issue here is that it is highly uncertain and questionable whether these improvements in carbon sequestration can be achieved. Prof Franke believes that for some companies, investments in regenerative agriculture have become a means to reduce the pressure to invest in curbing greenhouse gas emissions from fossil fuel use elsewhere.

Livestream of Graduation Ceremonies

Six days, eleven ceremonies, and more than 5 000 degrees. This all forms part of what is the biggest set of graduation ceremonies in the history of the University of the Free State (UFS).

The mid-year graduation ceremonies, taking place from 19 to 26 June 2017 in the Callie Human Centre on the Bloemfontein Campus, will see the most students graduate during a week. A total of 5 258 degrees, which includes 460 master’s and doctoral degrees, will be conferred – including 72 doctoral degrees.

First graduation ceremonies for Prof Petersen
It will also be the first ceremonies that Prof Francis Petersen, new Rector and Vice-Chancellor, attends on the Bloemfontein Campus. Students from all seven faculties, as well as the South Campus, will graduate.

Graduates per faculty are (without master’s and doctoral degrees): Faculty of Education (488), Faculty of Health Sciences (345), Faculty of Theology (29), Faculty of Law (686), Faculty of Natural and Agricultural Sciences (1 029), Faculty of Economic and Management Sciences (1 044), Faculty of the Humanities (826), and the South Campus (354).

Guest speakers include three judges
Guest speakers for the ceremonies include Dipiloane Phutsisi, Principal and Chief Executive Officer of the Motheo TVET College in the Free State, Dr Susan Vosloo, UFS Council member and founder member of the World Society for Paediatric and Congenital Heart Surgery, and Prof Petersen.

Three judges will also act as speakers. They are Justice Ian van der Merwe, Judge of Appeal at the Supreme Court of Appeal and former Chair of the UFS Council, Justice Mahube Molemela, Judge President of the Free State Division of the High Court and Acting Justice of the Supreme Court of South Africa, and Justice Connie Mocumie, Judge of Appeal at the Supreme Court of Appeal.
