The inauguration recognised Professor Magwaza’s contributions to research, teaching, mentorship and the advancement of sustainable food systems, as well as his work addressing pressing global food security challenges.
UMP Vice-Chancellor and Principal, Professor Thenjiwe Meyiwa, said that becoming a full professor represents much more than years of academic service, noting that the distinction is associated with sustained impact in knowledge creation, teaching, mentorship and the development of future scholars.
She also highlighted the importance of professors contributing to society by addressing complex challenges and advancing knowledge that responds to the realities of the communities they serve.
“Our vision as an institution is to strengthen our research ecosystem and create an environment in which scholarship can contribute meaningfully to African development,” she said, explaining the University’s ambition to transform existing research chairs into institutes and centres.
“We intend to invest in infrastructure that supports high-quality research and academic programmes, and to foster a Pan-African scholarly environment characterised by intellectual curiosity and social responsibility,” explained Professor Meyiwa.
Looking Beyond What Is Visible
Following the formal inauguration, Professor Magwaza delivered a lecture, titled Beyond the Naked Eye: Seeing the Future of Food Security, which brings together plant physiology, postharvest science, agricultural engineering, digital innovation, spectroscopy, imaging, machine learning and data science to develop non-destructive methods of assessing agricultural produce.
Professor Meyiwa has encouraged professors to address complex challenges and advance knowledge that responds to the realities of the communities they serve.
Professor Magwaza shared how securing sustainable and resilient food systems amid climate shocks, resource scarcity and increasingly complex supply chains is a defining global challenge; for example, more than a third of food produced globally is lost or wasted postharvest, resulting in substantial losses of nutrients, resources and economic value, while climate disruptions further intensify these losses.
“The research demonstrates how non-destructive sensors, optical imaging, and machine-learning approaches can reveal physiological and structural changes before they become visible, enabling earlier prediction and intervention to reduce food loss and improve postharvest resilience,” he explained.
Professor Magwaza's research explored circular bioeconomy approaches, including nutrient recovery and closed-loop hydroponic systems, as pathways towards resource-efficient and climate-smart food production.
“Addressing food insecurity requires moving beyond conventional, siloed approaches towards integrated, predictive, data-driven, circular, and adaptive food systems that can anticipate climate shocks, reduce losses, and sustain food security for future generations.”
The research demonstrated strong predictive relationships between imaging data and measurements obtained through conventional methods, highlighting the high predictive accuracy achieved through this work, which extends into plant physiology and climate resilience.
The inauguration recognised Professor Magwaza’s contributions to the advancement of sustainable food systems.
From Produce to Food Systems
Looking ahead, Professor Magwaza plans to integrate advanced technologies more deeply into agricultural production and food-quality assessment. One project is developing a prototype conveyor-belt system that combines infrared spectroscopy, hyperspectral imaging, laser profiling and ultraviolet illumination.
“The project has attracted approximately £780 000 in funding and aims to combine these technologies for a comprehensive assessment of agricultural produce,” Professor Magwaza said.
He also highlighted research on regenerative agriculture, plant-environment interactions, organic fertilisers, remote sensing, soil health and genomics.
These projects demonstrate how his research has expanded from analysing individual fruit characteristics to understanding and strengthening entire food systems.
The future of food security depends on replacing isolated approaches with integrated, predictive, data-driven, circular and adaptive food systems.
“It is how scientific knowledge and digital innovation can work together to tackle climate shocks, water scarcity, food loss and complex agricultural supply chains,” he said.
Professor Magwaza’s inaugural lecture underscored the need to look beyond the immediately visible and use science, technology and data to anticipate challenges before they become crises.
