Future of South Africa discussed at UFS peace conference
Delegates form the UFS and Osaka University gathered together at the Peace Conference.
The Department of Political Studies and Governance as well as the Centre for Africa Studies at the University of the Free State (UFS), together with the Osaka School of International Public Policy of Osaka University, jointly hosted a Quo Vadis South Africa Conference at the UFS on 12 and 13 February 2018.

Prof Hussein Solomon, Department of Political Studies and Governance, stated: “The focus is very much policy-oriented using academic insights to help resolve the myriad challenges confronting South Africa as a country as well as those on the continent.”

Prof Philippe Burger, Head of the Department of Economics and Acting Dean at the Faculty of Economic and Management Sciences at the UFS, spoke on the state of the national economy saying that factors contiguous to education could explain unemployment in South Africa. He pointed out that 60% of the population who were unemployed had not completed high school. He said only 20% of the employed population had tertiary education. Prof Burger said that labour-intensive, export-driven and investment-driven growth are the three integral sectors to consider when looking to improve the economy and overall growth of the country.

Prof Andre Duvenhage from North-West University delivered a presentation on his Strategic Perspectives of the ANC’s 2017 National Conference. Prof Duvenhage said that he had anticipated President Jacob Zuma’s recent departure from the ANC, saying his exit strategy had been negotiated behind the scenes. Some of his focal points included the state decay as a result of corrupt state practices, and the ideal future of the legitimate state which envisions the optimistic turn-around of the current condition of the South African Constitution.

“The future of Africa will be determined by politics”, said Jakkie Cilliers; Chairperson of the board, and Head of African futures and Innovation at the Institute for Security Studies. He explained that politics would drive events leading up to the national elective conference. This would offer political-election-outcome forecasts for 2019, 2024 and 2029 for the ANC, DA, EFF, and other national political parties.

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.
