Maricél van Rooyen, Project Manager for Research Information Management System (RIMS) and Research Ethics Adviser in the Directorate Research Development (DRD) at the University of the Free State (UFS), is the Programme Coordinator for a first-of-its-kind Southern African Research and Innovation Management Association (SARIMA)/ COP webinar on Environment and Biosafety Research Ethics.

The University of the Free State (UFS) is playing host to a first-of-its-kind webinar on Environment and Biosafety Research Ethics later this month with Maricél van Rooyen, Project Manager for Research Information Management System (RIMS) and Research Ethics Adviser in the Directorate Research Development (DRD), playing a pivotal role.

The webinar, which is part of the Eastern Region Community of Practice (COP), is taking place on 20 August. The target market for this virtual workshop is Biosafety and Environmental Research Ethics Committee (REC) chairpersons and members, professionals including research management professionals, administrators, research compliance managers and advisers, and research directors in Southern Africa and beyond.

Van Rooyen will be the Programme Coordinator for this Southern African Research and Innovation Management Association (SARIMA)/ COP Research Ethics Webinar, while Prof Robert Bragg, chairperson of the UFS Environmental and Biological Research Ethics Committee (EBREC), will give a presentation on the establishment of an EBREC.

The UFS, Stellenbosch University and the University of the Witwatersrand, form part of the COP which is a SARIMA (Southern African Research and Innovation Management Association) initiative to assist and share research ethics questions between institutions to empower research management and ethics compliance. SARIMA assisted with the online hosting and advertising of the webinar.

Purpose of the webinar

“Environment and Biosafety Committees in South Africa are a new idea, and only a few institutions in the country have such a committee. The UFS and the other institutions that will present at the workshop, take a leading role because they have already registered committees in place. We want to share and assist with establishing and operating such committees,” says Van Rooyen.

According to her, the need for the webinar arises from the upsurge of research and innovation in biotechnology and related fields over the past two decades that has led to exciting new discoveries in areas such as the engineering of biological processes, gene editing, stem cell research, CRISPR-Cas9 technology, Synthetic Biology, recombinant DNA, LMOs and GMOs, to mention only a few.

These advances, however, have generated concerns about biosafety, biosecurity and adverse impacts on biodiversity and the environment, leading to the establishment of Research Ethics Committees (RECs) at Higher Education and Research Institutions dedicated to reviewing research with implications for biosafety and the environment.

These EBRECs are in the early stages of their establishment and formalisation in South Africa, and there is much uncertainty about their composition, scope, procedures of decision-making and the principles that should guide their deliberations and assessments.

Leading the charge

The UFS took the lead in South Africa in ensuring international ethical compliance in this extended area of research, by establishing its own Environmental and Biological Research Ethics Committee (EBREC) six years ago. The UFS EBREC is one of only two such ethics committees at a South African university that combines the biosafety committee with environmental and biological research ethics to ensure ethics compliance in these fields.  The initiative started with Van Rooyen and her RIMS EthicsTeam, (Willem Kilian and Amanda Smith). The university is again taking charge with this webinar, which is a first of its kind.

Fire as a management tool questionable in arid and semi-arid grassland areas

The influence of fire on the ecosystem in the higher rainfall ‘‘sour’’ grassland areas of southern Africa has been well established. However, less information is available for arid and semi-arid ‘‘sweet’’ grassland areas, says Prof Hennie Snyman, Professor in the Department of Animal, Wildlife, and Grassland Sciences, about his research on the short-term impact of fire on the productivity of grasslands in semi-arid areas.

Sour and sweet grassland areas can be defined as receiving either higher or lower than approximately 600 mm of rainfall respectively. In quantifying the short-term impact of fire on the productivity of grasslands in semi-arid areas, a South African case study (experimental plot data) was investigated.

“Burned grassland can take at least two full growing seasons to recover in terms of above- and below-ground plant production and of water-use efficiency (WUE). The initial advantage in quality (crude protein) accompanying fire does not neutralise the reduction in half of the above-ground production and poor WUE occurring in the first season following the fire.

“The below-ground growth is more sensitive to burning than above-ground growth. Seasonal above-ground production loss to fire, which is a function of the amount and distribution of rainfall, can vary between 238 and 444 kg ha -1 for semi-arid grasslands. The importance of correct timing in the utilisation of burned semi-arid grassland, with respect to sustained high production, cannot be overemphasised,” said Prof Snyman.

In arid and semi-arid grassland areas, fire as a management tool is questionable if there is no specific purpose for it, as it can increase ecological and financial risk management in the short term.

Prof Snyman said: “More research is needed to quantify the impact of runaway fires on both productivity and soil properties, in terms of different seasonal climatic variations. The information to date may already serve as valuable guidelines regarding grassland productivity losses in semi-arid areas. These results can also provide a guideline in claims arising from unforeseen fires, in which thousands of rands can be involved, and which are often based on unscientific evidence.”
