Insights into the sustainable use of medicinal plants and underutilised food crops

The recent launch of the first books ever edited within the Department of Horticultural Sciences is truly a momentous occasion for the department.

Held at the Cape Town Hotel School, this event brought together passionate authors from across the globe, including valued contributors from CPUT and various universities in South Africa, India, Nigeria, Mozambique, Namibia, and Zimbabwe. Prof Learnmore Kambizi from the department says it was heartwarming to see such collaboration and dedication to horticultural knowledge, and it highlights the strength of their collective efforts in advancing this field. Over the past two years, Kambizi and Dr Callistus Bvenura have co-edited two books published by CRC Press: Sustainable Uses and Prospects of Medicinal Plants (2024) and Food Security and Nutrition: Utilizing Undervalued Food Plants (2025). Due to various commitments, the launch of the first book was postponed, leading to the decision to host a dual launch. “This event not only promoted both books but also highlighted significant research contributions at the departmental, faculty, and university levels,” Khambizi notes.

The launch was a tremendous success, highlighted by the signing and presentation of autographed copies to Prof Dina Burger, Director of Research Development, and Prof Joseph Kioko, Dean of Applied Sciences.

Kambizi attributes the successful completion of the books to the invaluable contributions of global experts in fields such as medicinal plants, ethnobotany, botany, agronomy, and food security. Through effective editorial coordination, unwavering institutional support, and a steadfast commitment to rigorous academic standards, this ambitious project was brought to fruition on time.

“Partnering with CRC Press and engaging diverse researchers enriched the content, making these publications a significant milestone in advancing knowledge on medicinal plants and food security.”

He mentions that their ability to write these books was fuelled by "our collective" expertise in medicinal plants, phytochemistry, food security, and agronomy, along with contributions from researchers worldwide. Their goal was to address knowledge gaps regarding the sustainable use of medicinal plants and undervalued food crops, thereby advancing scientific discussion and promoting food security.

“Our goal was to create a valuable resource for researchers, policymakers, and industry professionals. It’s amazing that the first book took two years to complete, as such dedication really shows their commitment to their craft. It’s also impressive that the second book came together in just a year.”

The two books have been warmly embraced, highlighted by the many emails from other publishing houses expressing their interest in having them edit books or contribute to special issues. They have been receiving royalties quarterly as proceeds from the sale of the first book, indicating that it was well received. The target audience for these books includes researchers, academics, policymakers, and industry professionals who are dedicated to fields such as agriculture, food security, medicinal plants, and nutrition.

These books are thoughtfully crafted to provide deep insights into the sustainable use of medicinal plants and underutilised food crops. They highlight the vital role these resources can play in addressing the pressing challenges of global food security and health. The authors believe these works can be invaluable to those striving to advance research, encourage interdisciplinary collaboration, and promote sustainable practices in agriculture and nutrition.

Now that the book has been launched, the authors feel an immense sense of accomplishment and pride. “After years of hard work, collaboration, and dedication, it's incredibly rewarding to see our efforts come to fruition. We are excited knowing that our work will contribute to the broader academic community and make a lasting impact in the fields of food security, medicinal plants, and sustainable agriculture. We are also grateful for the support and contributions of our co-authors, collaborators, and everyone who played a part in making this project a reality. This launch marks a significant milestone, and we’re thrilled to have reached this point.”

Bvenura states that the books represent a major advancement in understanding sustainable practices related to food security and the utilisation of medicinal plants. “The launch event was a proud moment for me, as it marked the culmination of years of hard work, collaboration, and dedication. Bringing together diverse perspectives and expertise from around the world, the books offer valuable insights into the potential of undervalued food crops and the role of medicinal plants in promoting health and nutrition,” Bvenura remarks.

He continues: “I would like to extend my heartfelt thanks to the co-editor Prof Learnmore Kambizi, whose expertise, guidance, and dedication were instrumental in shaping these books into what they are today, the authors for their invaluable contributions, as well as to CPUT for providing an enabling environment that supported our research and the development of these books.”

Bvenura conveyed a special thank you to their families for their subliminal yet critical support throughout this journey.” He is thrilled to have contributed to these works and hopes they inspire further research, collaboration, and innovation in these critical areas. “The launch not only celebrated our collective efforts but also served as a milestone in the academic and research communities, providing a comprehensive resource for those working to address global challenges.”
