University of the Free State (UFS) Alumni may be based all around the world, but the United Kingdom (UK) Alumni Chapter aims to reconnect with all those members.

The UK Chapter is a hub of a developing UFS international programme. “We want to provide an opportunity for alumni to share their university experiences with wider audiences,” explains Carmenita Redcliffe Paul, Assistant Director: Alumni Relations and Business Development at the UFS.

Platform to celebrate successes

“The programme aims to provide a platform to alumni to celebrate their successes and provide a window to the landscape of the life and times of the university and the people who shaped it.”

“We also want to celebrate the diversity of our former students and the many touchpoints which unite them.”

Two key projects, Global Citizen and Voices from the Free State, came to life as a result of the collective collaboration of this chapter. The Global Citizen invites people in a series of “courageous conversations” to rethink their relationship with the world. Voices from the Free State is a series of personal podcast narratives by outstanding alumni wherein they reflect their experiences at the UFS. They tell their stories and explain how their university years shaped their future and paved the way to their respective successes.

Relevant association with the UFS

“Furthermore, they motivate why their ongoing association with the UFS is still relevant and important,” says Redcliffe Paul.

The UK Alumni Chapter is led by alumni Francois van Schalkwyk and Keenan Carelse and supported by Adrienne Hall.

Redcliffe Paul says Carelse and Van Schalkwyk have been instrumental in the Voices from the Free State initiative as they are strategically and operationally invested. They create and co-host the podcast series.

Van Schalkwyk is an entrepreneur and innovator consulting with clients globally. Carelse is employed in the healthcare sector in the UK.

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.
