Green Futures Hub
Prof Wayne Truter, who is leading the Green Futures Hub at the UFS, highlights that mining and agriculture are important yet competing industries in South Africa. The hub aims to find sustainable ways for them to coexist.

Our earth is very resilient, and a green future is possible, but we must make changes. At the forefront of this mission is the Green Futures Hub, spearheaded by Prof Wayne Truter at the UFS. Prof Truter holds a PhD in Integrated Agricultural and Environmental Sciences, with more than 25 years of experience. He is a leader in the field of forage, pasture, and land regeneration – particularly those impacted by mining. 

The Green Futures Hub is a virtual platform that bridges academic research and industry gaps, aiming to solve real-world challenges with scientific insights. It is designed to showcase and integrate the research happening across various disciplines at the University of the Free State (UFS), making it accessible to industry and communities alike. “People often lose faith in academic institutions, thinking that the research done there has no practical value,” Prof Truter notes. “The Green Futures Hub aims to change that by making scientific findings accessible and relevant to daily life.” 

This platform offers a unique opportunity for industries to connect with researchers working on solutions related to climate change, sustainable agriculture, or environmental rehabilitation. “Our hub is a space where industries can come to us with their challenges, and we can offer solutions based on research,” Prof Truter explains. “It’s about creating real impact.” 

Collaboration and integration are central to the Green Futures Hub’s approach. “Through interdisciplinary collaboration and a commitment to environmental stewardship, we want to develop solutions to the complex development challenges related to ecosystems, agroecosystems, water resources, biodiversity, infrastructure, and communities,” says Prof Truter. 

One of the hub’s projects that is close to Prof Truter’s heart, is the future coexistence of mining and agriculture. Mining and agriculture are two important industries in South Africa, often competing for land. However, the hub seeks to bridge this gap by exploring how these industries can coexist sustainably.  

“The future coexistence of mining and agriculture is critical,” says Prof Truter. “While mining often uses the land intensively, they have the responsibility and capability to rehabilitate it for agricultural use, ensuring that it is as productive – if not more – than it was before. Farmers and miners have much to gain from each other,” he explains. “By partnering with industries, we can help rehabilitate the land that has been mined, and in turn, farmers can harness and bring back the productivity to that land with the financial inputs of mining companies.” 

Prof Truter also emphasises the importance of science communication. “We need to do better at communicating the value of the research we’re doing. Many times, industries don’t understand the significance of what we’re working on because it’s not explained in a way that resonates with them. The hub ensures that research findings are accessible, understandable, and applicable to real-world issues.”  

The Green Futures Hub is more than just a research platform; it is a testament to the power of collaboration between academia and industry. “We’re not just conducting research,” Prof Truter concludes, “we’re developing solutions.”

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.
