This formed the central theme of a public lecture delivered by Dr Buyiswa Hlangothi, Senior Lecturer in Organic Chemistry at Nelson Mandela University, during the 10-year anniversary celebrations of the Manicaland State University of Applied Sciences (MSUAS) in Mutare, Zimbabwe.

Presenting on the topic “Is Modern Science an Enabler for the Exploitation of African Medicinal Plants?”, Dr Hlangothi examined the complex relationship between scientific advancement and the protection of indigenous knowledge systems.
Opening the event, MSUAS Vice Chancellor, Professor Albert Chawanda, reaffirmed the institution’s commitment to advancing research that supports national development while preserving Africa’s knowledge heritage.
He emphasised that innovation at MSUAS is guided by ethical responsibility, in line with the principles of Education 5.0.
In her lecture, Dr Hlangothi highlighted that whereas modern science plays a critical role in validating the medicinal properties of African plants, it also raises concerns around exploitation and commercialisation, often without fair recognition or benefit-sharing for local communities.
She cautioned that without strong ethical frameworks, scientific progress risks marginalising indigenous knowledge holders.
She called for a balanced approach that promotes innovation, also safeguarding cultural heritage, urging researchers, academics and students to adopt ethical practices that ensure that communities benefit from their knowledge systems.
Engaging dialogue on science and society
The lecture sparked vibrant discussions among students, staff and stakeholders, reflecting strong interest in the intersection of science, ethics and indigenous knowledge. Participants explored how research can contribute to sustainable development, yet remain socially responsible.
“Africa is not just vulnerable; it is a site of innovation and biodiversity. Community involvement is non-negotiable when conducting research on indigenous plants,” Michelle Fuyane from the Centre for Education Innovation Research and Development (CEIRD) said.
“This engagement provided an opportunity to strengthen how I present the chemistry of African medicinal plants within broader discussions. It also opened avenues for collaboration across applied science fields such as IT, engineering, environmental science, and chemistry,” Dr Hlangothi said.
She added that engaging with the MSUAS audience reinforced the importance of conducting research that speaks to African contexts and involves not only academics, but also communities. “The interaction reminded me of the value of inclusive engagement and the need to ensure that research remains relevant and beneficial to society,” she noted.
Dr Hlangothi also expressed her appreciation to MSUAS for the opportunity to contribute to the institution’s milestone celebrations. This engagement reflects Nelson Mandela University’s ongoing commitment to advancing impactful, ethically grounded research and strengthening academic collaboration across the African continent.
