UFS Division of Student Affairs plans to extend their annual research colloquium to involve other universities, establishing the university as a pioneering institution of higher education and learning.
The annual University of the Free State (UFS) Division of Student Affairs Research (DSA) Colloquium aims to promote a culture of research embedded in data-driven and evidence- based practices in the field of Student Affairs. The purpose of the annual colloquium is to create a safe, enjoyable space for staff members to share their experiences, knowledge, research and practices.

The 2020 Student Affairs Research Colloquium was the first virtual Research Colloquium held by the university. As noted by DSA Researcher Ruben Langenhoven, this year’s theme Virtually Human: Connecting Meaningfully in a Digital World was inspired by the challenging times we live in, and thus commemorated the resilience and adaptability UFS Student Affairs practitioners, academic staff and students. 

As most of the projects and programmes in the DSA were negatively impacted, the Colloquium was threatened by a lack of “hard data” emanating from the 2020 academic year. The division consequently decided to reframe the colloquium by profiling distinct human voices that focused on qualitative experiences. As such, this Colloquium comprised of numerous sections where the emphasis was placed on shared experiences and shared understanding where UFS staff members and students discussed the challenges they faced in the last six months.

DSA staff engaged one another with staff and student-centered lived experiences, and professional staff development sessions that visited the impact of technology on their psychological well-being and how to improve their relationship with technology in light of the COVID-19 pandemic. Also forming part of the programme that will inform the future of the division going forward, reflected DSA success-story presentations of the past year. 

The colloquium proved as beneficial for the DSA and the entire institution in its pursuit of a research-based working approach within the Student Affairs discipline.

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
