Dr Juliet Kamwendo champions gender-inclusive climate action in Africa. Her expertise at the recently held AFR100 workshop highlighted vital steps towards sustainable and equitable development.
Dr Juliet Kamwendo, Lecturer and Programme Director for Gender Studies in the Centre for Gender and Africa Studies at the University of the Free State, is spearheading efforts to integrate gender considerations into Africa's climate restoration agenda. Reflecting on her involvement, Dr Kamwendo stated, "This is particularly crucial, as women make up almost 50% of the population in Africa, and the depletion and degradation of land affect them disproportionately."
She recently served as a gender expert at the AUDA-NEPAD AFR100 workshop in Ouagadougou, Burkina Faso, from 25 to 29 March 2024. This initiative aims to restore forests and degraded land across Africa by 2030, with a focus on gender equality.
The workshop emphasised the integration of gender perspectives into the AFR100 project, acknowledging the disproportionate impact of land degradation on women. Dr Kamwendo's expertise highlighted the need to empower women in climate change interventions, addressing existing gender inequalities exacerbated by environmental degradation.
“Women – who are primarily responsible for household food security and water provision – bear the brunt of environmental degradation, leading to increased workloads, reduced income opportunities, and heightened vulnerability to climate-related disasters. Furthermore, the loss of forest cover and biodiversity further exacerbates the challenges faced by women, particularly in rural areas where they depend heavily on natural resources for their livelihoods,” added Dr Kamwendo.
Her participation highlights academia's crucial role in fostering inclusive and sustainable development, emphasising interdisciplinary collaboration to tackle complex environmental challenges. Through initiatives such as AFR100, stakeholders are working towards a more resilient and gender-responsive future for Africa.
Prof Tredoux turns theories regarding the formation of metals on its head

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.
The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.
This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.
Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.
The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.
For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.
“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”
Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
