New member of the Pontifical Academy of Social Sciences - Prof Pearl Sithole

Social scientist and Vice-Principal: Academic and Research on the Qwaqwa Campus, Prof Pearl Sithole, was appointed by Pope Francis as a member of the Pontifical Academy of Social Sciences for her stellar work in social sciences. 
Academicians are appointed by the Pope on the basis of their competencies in the social sciences and their moral integrity.

Prof Sithole said she was looking forward to sharing meaning and impact with the world through a space dedicated to the social sciences. “It’s a great honour. I’m feeling really humbled. The social sciences and humanities are a hugely necessary space to make meaning of the world, but for some reason, in the pecking order, they were relegated to a space that is thought of last. This appointment is to a dedicated space – to say, let’s look at issues through that lens.”
The Pontifical Academy of Social Sciences was established by Pope John Paul II in 1994 with the aim of promoting the study and progress of the social sciences, primarily economics, sociology, law, and political science. To achieve its aims, the academy organises conferences and workshops on specific themes, promotes scientific surveys and research, and publishes publications. 

Prof Sithole said the academy provides a wonderful way of reminding academicians of the importance of relating science to the real world. 

“What I like about it is that it demystifies science. It says, be excellent in your field but be able to converse for impact, be able to come to a forum that worries about specific issues, it still encourages publications and pure science/scientific endeavours, advancements in their field, but sometimes people come together to look at an issue from various angles. For me, it’s such a wonderful way of saying we must remember that we are doing science in order to relate to the world, not just to understand for the sake of understanding,” she said.

Make a genuine effort to make a difference in whatever you do, and your work will speak for itself.- Prof Pearl Sithole. 

The appointment also coincides with Women’s Month, and Prof Sithole said she takes great pride in her womanhood. 

“I am a mother and a daughter. I strive to pinpoint problems and offer solutions. I am a social scientist. I’ve made it a mission to study how systems affect people by infusing humanity within the systems. Women have been made to be apologetic about the qualities that define us as women, which we bring especially into leadership. I don’t apologise for my emotions. I don’t apologise for my multitasking abilities; however, I do feel that women are often abused for having these.”

What would you say makes you a UFS woman of quality, impact, and care?

I am the sort of person who strongly believes that your work should speak for itself. I don’t work for accolades. My approach to life is to work genuinely to make a difference, and your work will speak for itself. If you wake up every day to genuinely make a difference, it is enough. You get a lot of satisfaction in life, and you sleep better because you know you have given it your best, and you know that sometimes you can actually see it making a difference.

What advice would you give to the 15-year-old you?

I would say, be true to yourself. At a younger age, you want to chase all sorts of aspirations that look glamorous, which is not a bad thing, because you have to have appetite; but in your appetite for excellence and as someone who lives for a purpose, be true to yourself. Be able to design a life that aspires, but at the same time be adaptable to what you discover your strengths to be.

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.
