Prof Ashok Chapagain has recently been appointed as Senior Professor in the Department of Agricultural Economics in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS). 

Water hub key in collaborations with research institutes

According to Prof Chapagain, the position provides a unique opportunity to help establish the university at the forefront of water research in South Africa. He is looking forward to cross-departmental collaborations on innovative research projects working with key water-related sectors, such as agriculture, business, mining etc., and establishing a water hub that would be key in external collaborations with other research institutes in South Africa and beyond.

Prior to his formal appointment at the UFS, Prof Chapagain has been remotely involved with the Department of Agricultural Economics since 2017 through his support to a number of research projects funded by the Water Research Commission (WRC). 

He is experienced in managing and coordinating international and interdisciplinary projects, ensuring technical quality and project delivery. He has vast cultural and geographical work experience, and specific water-related experience in the fields of integrated water resource management, water footprint assessment, industrial and agricultural efficiency and sustainability, irrigation, hydrology and watershed modelling, flood-risk management, river-basin planning and management, and environmental impact assessment. He has recently left the Water Footprint Network (The Netherlands), where he worked in the capacity of Science Director. Prior to joining the WFN, Prof Chapagain worked as Senior Water Adviser at WWF-UK for about six years.

Systems approach to address water issues

Prof Chapagain holds a PhD in the field of Water Resources Management and Policy Analysis from Delft University of Technology (The Netherlands), an MSc degree in Water and Environmental Resources Management from UNESCO- IHE Institute for Water Education (The Netherlands), and a Bachelor’s in Civil Engineering from IIT Roorkee (India). His professional career of 28 years can be broadly grouped under two inter-related blocks: development projects for 10 years (as an irrigation engineer in Nepal); research and application for 18 years (academia for eight years and applied work for 10 years in the Netherlands and UK). During his MSc and PhD research, he specialised in water resources and environmental management, integrated river-basin management, policy analysis, and systems analysis.

He regularly reviews articles for several scientific journals. Currently he serves as the Editor-in-Chief for the recently launched open access scientific journal H2Open, published by IWA Publishing. In addition, he serves as editor for five scientific journals, and frequently guest edits specific issues for peer-reviewed scientific journals. He has published four books, and 64 other articles and reports (25 scientific journal articles, 40 papers in conference proceedings, book chapters, and technical reports). His publications are widely cited, with 10 436 citations, and has an h-index of 34 and i10-index of 44. He applies a system approach in addressing issues on water, energy, and food securities, where managing local resources also includes global dimensions where key stakeholders are often cross-sectoral and situated outside the boxes. He has been involved in many national and international projects as a team leader, project leader, and international expert in several Asian, European, and South American countries.

Dr Charlotte Boucher and Lindi Heyns examine possible anti-microbial activity in the skin of Western olive toad species
2014-12-22

 

Researchers Lindi Heyns and Dr Charlotte Boucher are working together on an interdisciplinary project between the Departments of Zoology and Entomology and Veterinary Biotechnology at the University of the Free State (UFS). The focus of their research is on the preliminary biochemical description of skin secretions in some South African toads.

The project forms part of an Honours study executed by Dwayne Pike under Heyns’ supervision. He is co-supervised by Dr Boucher who is assisting with the biochemical and microbiological assays.

Dr Boucher said, “Amphibians are characterised by the presence of cutaneous glands spread over the skin. There are two types of glands, namely mucous and granular (poison), located on the inner surface of the epidermis. Mucous glands are widely dispersed over the skin, while granular glands can be grouped and enlarged in specific regions. Mucous glands are generally associated with maintenance of humidity and cutaneous respiration, whereas granular glands function in chemical defence against predators and/or microbial infection. Studies indicate that the compounds produced by the granular glands belong to numerous chemical classes with diverse pharmacological activities.”

The products secreted by granular glands are rich in low molecular weight constituents of varied molecular types, including proteins, peptides and toxins. These secretions make the toad foul-tasting to predators and even toxic to other frog species. In addition, amphibians offer an attractive source of novel antimicrobials. Studies indicate that as a response to inhabiting microorganism-rich environments they synthesise and secrete a diverse array of antimicrobial peptides (AMPs) as an innate form of defence. Extensive research by various other research groups has been carried out on antimicrobial peptides of the genus Rana; however, hardly any studies have investigated the antimicrobial activity of African frog species.

The focus of this preliminary project is to determine the protein composition of the glandular secretions of the Western olive toad (Amietophrynus poweri), using biochemical tests, such as SDS-PAGE also known as protein gel electrophoresis combined with mass-spectrometry used to identify unknown peptides and proteins. This will give us an overview of the composition of the glandular secretions. Furthermore, we are also looking at microbiological tests, which include assays that test for possible anti-microbial activity against various bacterial and fungal species.
