High-profile positions at National Treasury, the World Bank and now also the International Monetary Fund in Washington, mark an illustrious career for UFS Economics alumna, Vuyelwa Vumendlini.

“Go in full force, hands and feet, and accept this opportunity of a lifetime. You won’t regret it.” These words of Dr Minette Smit, her thesis supervisor, proved to be pivotal advice to a young Vuyelwa Vumendlini. At the time, she was doing her BCom Honours in Economics (1996-1999) and was presented with a scholarship opportunity to complete her master’s degree in the USA.

“I was afraid to leave my home and my comfort zone,” she explains. “But looking back, I’m extremely grateful to have taken that step.”

Her studies culminated in an appointment as Senior Adviser to the Executive Director at the World Bank, then Deputy Director-General: International and Regional Economic Policy at the National Treasury, and now as Alternate Executive Director at the International Monetary Fund (IMF) in Washington DC. As an IMF executive board member, Vumendlini represents 23 English-speaking African countries that are members of a constituency. The Executive Board of the IMF has 24 chairs, representing 24 constituencies from its 189 countries’ membership. Among her duties are considering policy issues and surveillance reports, as well as approving and monitoring IMF programmes involving lending and/or technical assistance.

Since this is the second stint in Washington for her and her children, Simphiwe, Enhle, and Anele, settling down was much easier. “Because of the COVID-19 isolation, we were kind of used to being alone at home, so we didn’t find the solitude that bad while we were still making new friends.”

She misses South African food the most – things like biltong and boerewors – and the proximity of favourite restaurants like Ocean Basket and Mugg & Bean. She has fond memories of her study years, working as an assistant in the Department of Economics, hanging out at Mooimeisiesfontein on Saturdays, and building rag floats for Vergeet-My-Nie and Kestell residences. Plans for the future include tackling her PhD in Economics.

Her advice to UFS students: “Be up to date with what is happening around you. Do not be afraid to do things differently. Be agile in your approach to achieving your career aspirations and be ready to take on those opportunities when they present themselves.”

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.
