UFS and CUT joint SASUF Research Symposium discusses urbanisation

The University of the Free State (UFS) and the Central University of Technology (CUT) recently joined hands with the Swedish University Forum (SASUF). The universities jointly presented at a research seminar with the theme: ‘Urban Rural Dynamic’. The seminar was a side event to the stream ‘Urbanisation in the 21st Century’ of the SASUF Sweden-South Africa Research Week that took place in the same week. This stream of the research week was academically chaired by Wanda Verster from the UFS Department of Architecture. 

SASUF is a collaboration of 30 universities in Sweden and South Africa together with embassies, civil society organisations, funding agencies and ministries in both countries of which CUT and UFS are partners. Other themes of the research week were ‘Climate Change, Natural Resources and Sustainability’; ‘Transforming Higher Education Curricula’; ‘Social Transformation Through Change’; ‘Understanding the Burden of Disease’; and ‘Digital Technologies, Big Data and Cybersecurity’. One of SASUF’s main goals is to connect researchers with funding agencies, industry, ministries, and society in working towards the Sustainable Development Goals. 

Tri-partite between local and international universities
The first day of the event was hosted by the UFS Department of Architecture on the Bloemfontein Campus and was supported by the UFS Department of Urban and Regional Planning

The focus of the seminar was on the rural/urban dynamic that secondary cities are frequently experiencing.

Researchers from the UFS, CUT and Malmö University in Sweden presented at the seminar. Stuart-Denoon Stevens, an honours student from the Department of Urban and Regional Planning at the UFS, presented his research on human settlements. “There are 200 million informal settlements in Africa. In 1994 there were 260 informal settlements in South Africa. Today we have 2600 informal settlements,” said Stewart. 

Take hands, not handouts
He believes that one needs to support what is happening rather than introduce new technology all the time. “Take hands, not handouts,” he said. 

Presenters from the CUT included Dilip Das, who presented on sustainable urban roads and transport, as well as Oke Saheed, who gave an overview of research on sustainable water resources and environment. Prof Nils Ekelund, the head of the Department of Science, Environment and Society at Malmö University in Sweden, presented on perceptions of the ecosystem services concept. He presented together with his colleague, Per Schubert, a lecturer in physical geography. 

The Director: Internationalisation at the UFS, Cornelius Hagenmeier, stressed in his welcoming remark the contribution SASUF and the side event organised by UFS and CUT make toward comprehensive internationalisation and strengthening the local collaboration between the two universities in Bloemfontein.

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.
