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.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.
Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.
The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).
According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.
In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.
“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.
H.E.S.S. has issued a complete statement about the paper published in Nature.
