Soil Confrence at UFS
At the Combined Congress with the theme ‘Basic and applied sciences – Fundamentals of sustainable agriculture’, were from the left: Prof Klaus Kellner, Prof Prakash Naidoo, Dr Cobus Botha from the Agriculture Research Council, Prof Vaughan Hattingh, and Mr Matome Ramokgopa.

“We are at the beginning of a new decade that will in all likelihood be pivotal for aspects such as food security, climate change, and the sustainable use of natural resources – aspects that the societies you represent are of course keenly involved with – and in terms of which you can play an increasingly valuable role.” 

These were the words of Vice-Rector: Operations at the University of the Free State (UFS), Prof Prakash Naidoo, on opening a Combined Congress of the Soil Science Society of South Africa (SSSSA), the South African Society of Crop Production (SASCP), the Southern African Weed Science Society (SAWSS), and the Southern African Society for Horticultural Sciences (SASHS).

The UFS Department of Soil, Crop and Climate Sciences is hosting the congress, with scientific content of four disciplines (soil, crop, weed, and horticulture) presented by both local and international guest speakers.

The theme of this year’s congress taking place on the UFS Bloemfontein Campus, is Basic and applied sciences – Fundamentals of sustainable agriculture.

Prof Naidoo continues: “It has been predicted that the world will need almost double the current food supply by 2050 to feed an ever-increasing world population. This clearly makes the scientific work done in the agricultural sector and the organisations affiliated with it, more vital than ever. We need to do what we can to ensure food security and sustainability.”

“A congress like yours is an opportunity to tap into the perspectives and research results of collaborators from different fields, and from different levels of skill and experience – with the aim of ultimately benefiting wider communities.”

Leader in agriculture sector

Prof Vaughan Hattingh, representing SASHS (Chief Executive Officer of Citrus Research International); Mr Matome Ramokgopa, representing SASCP (General Manager of Enza Zanden SA); and Prof Klaus Kellner, representing SSSSA (Department of Botany at the North-West University), delivered the combined opening address.

Prof Hattingh, speaking on ‘Industry–University partnership opportunity road ahead for horticultural research’, says citrus is a major horticultural product internationally and the biggest horticultural export from South Africa. The citrus industry, the second largest exporter of citrus in the world, generates R20 bn per year and is the biggest funder of research in this area. 

Prof Hattingh states that university partnerships, developing science to assist the industry, are key. “The future of horticultural industries and horticultural research at universities depends on successful university-industry partnerships.”

Mr Ramokgopa talked about ‘Innovative solutions for vegetable seed production for a growing population’, saying that Enza Zanden employed several techniques in vegetable production in response to the needs of retailers and consumers. These include smaller tomatoes (for snacking purposes), smaller leaf size of lettuce (thus a smaller area for decay), plastic-free packaging of cucumber with a longer shelf life, and more uniform onions (suitable for onion rings). 

Prof Kellner focused on ‘Scientifically sound policies and practices to ensure food security and sustainable agriculture’. He said: “It is getting warmer in Southern Africa and Europe. We need to realise it and adapt practices accordingly.”

More discussions on sustainable agriculture

Other interesting topics covered at the congress include, ‘Developing propagation technologies for indigenous plants used in the natural products industry’; ‘The influence of foliar and application rate of nitrogen fertiliser on seed and oil yield of canola’; ‘Sweet potato production in sacks: potential utilisation of limited space in rural, urban and peri-urban areas’; ‘The efficacy of postharvest wax application in the reduction of chilling injury incidence in lemon fruit’; and ‘Herbicide use within the commercial forestry sector in South Africa’.

Congress attendees can also look forward to the ‘Soil fertility and crop nutrition symposium: principles and practices’ on Wednesday 22 January 2020.

The congress kicked off on 21 January, and will come to an end on Thursday 23 January 2020. For more information on the sessions, see programme.

Many people are interested to know more about their history and origins, and with the help of genetics, it is possible to provide more information about one’s roots.

During a lecture at the Department of Genetics at the University of the Free State (UFS), Dr Cristian Capelli, Associate Professor of Human Evolution at Oxford University in the UK, addressed staff members and students on the history of our species.

Reconstructing the history of human population
With his research, titled: People on the move: population structure and gene-flow in Southern Africa, Dr Capelli looks at reconstructing the history of human populations, focusing mainly on how the different human populations are related, as well as how they exchange genes.

He said this research could be of great significance to the medical field too. “Knowing what the genetic make-up of individuals is, can give us some information about their susceptibility to diseases, or how they would react to a given medicine. Therefore, this knowledge can be used to inform health-related policies.”

Combining individual histories of multiple people
To understand this research more clearly, Dr Capelli explained it in terms of DNA and how every individual receives half of their DNA from their mother and half from their father just as their parents had received theirs from their parents. And so it goes from generation after generation. Each individual stores a part of their ancestors’ DNA which makes up the individual genetic history of each person.

“If we combine these individual histories by looking at the DNA of multiple people, we can identify the occurrences that are shared across individuals and therefore reconstruct the history of a population, and in the same way on a larger scale, the history of our own species, homo sapiens.
