CGAS awards second AS scholarship Chetima Melchisedek
Chètima Melchisedek is the recipient of the UFS/AS Young African Scholarship is planning a visit to the UFS Centre for Gender and Africa Studies in 2019.
Chétima Melchisedek from the University of Ottawa, Canada, has been awarded the 2018 UFS/AS Young African Scholarship. “An award like the UFS/AS Young African Scholar is a great accomplishment for a young scholar,” said Chétima.

Melchisedek is the 2018 Gordon F Henderson Fellow at the Human Rights Research and Education Centre at the University of Ottawa and is affiliated  with the University of Maroua in Cameroon. “I am also very happy and honoured to be affiliated to the Centre for Gender and Africa Studies (CGAS) at the UFS. To be able to work with the university is a privilege I am delighted to receive.”

He says the disciplines within Africa studies should be researched by Africans from the continent. “My aim was also to be able to share my knowledge through publications in established journals. In fact, today, this is the only way to be recognised as an authoritative voice on African studies from Africa,” he said.

Scholarship provides platform to young researchers 
The Young African Scholar Award is an initiative by the Centre for Gender and Africa Studies. It seeks to strengthen efforts to promote internationally recognised African scholarship within Africa Studies.   

The programme provides young researchers the platform to publish their work and to build an international network with organisations such as the German Institute of Global and Area Studies (GIGA), the German African Studies Association (Vereinigung von Afrikanisten in Deutschland/VAD), and the UFS Centre for Gender and Africa Studies.

“The award is given to the best, publishable research article contribution by an emerging African scholar to the prestigious African Spectrum journal,” said Dr Stephanie Cawood, Acting Director of CGAS. The prerequisite for the award is that applicants must be from Africa or affiliated with African institutions.  

As part of the prize, the winner receives a three-year affiliation as research fellow with the UFS GGAS and prize money of R5000.

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.
