The Library and Information Services of the University of the Free State (UFS) and the Central University of Technology,Free State (CUT) jointly hosted an Open Science Colloquium on 19 November 2019. The colloquium was in response to the national and international developments in what is referred to as ‘the Open Access 2020 (OA2020) movement’. This movement calls on all parties involved in scholarly communication to take action to make their scholarly outputs open and freely available to all citizens of the world. It is a move against the current subscription-based model of publication, which has proved to be costly and unsustainable, and which limits access to knowledge to a few, making it unacceptable.

Welcoming more than 200 delegates to the UFS, Ms Betsy Eister, Director: Library and Information Services, referred to OA2020 as a disruption in the publishing arena.

Endorsing the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities

The colloquium comes as an endorsement of the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities that the two universities signed eight years ago. As signatories, the UFS and CUT have committed to the wide and free dissemination of its scholarship by means of open access platforms. This declaration was confirmed by the Rector and Vice-Chancellor, Prof Francis Petersen.  

“When the UFS signed the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities in 2011, this university committed itself to the wide and free dissemination of its scholarship by means of open access platforms. At that point, we have already made that commitment to open access platforms.”

Open access vs subscription

Prof Petersen said challenging the current status quo will bring equity into the system, which  will “ensure that our younger cohort of researchers and scholars have the ability to freely conduct research, to freely access material, so that we can produce high-quality researchers and scholars for our system”. 

Also present was Prof Ahmed Bawa, Chief Executive Officer of Universities South Africa, who echoed Prof Petersen’s message by making a case for management, researchers, libraries and research funders to work together to make OA2020 a reality. “These discussions are very important because it provides us with an opportunity to build international consensus on these things, which is critical in moving forward.”

Prof Ahmed Bawa

Prof Ahmed Bawa, Chief Executive Officer of Universities South Africa addressed delegates on the importance of open access. 

Mr Glenn Truran, Director of the South African Library and Information Consortium (SANLiC), and Ms Eister addressed the national and local roadmaps, respectively. SANLiC, a consortium that negotiates deals for electronic resource subscriptions on behalf of all 26 public universities and eight research councils, has already started transformative agreement negotiations with international publishing company Taylor and Francis. 

The colloquium ended with a declaration signed by members present, hoping that it would be signed by all concerned as a commitment to taking action towards open access.  The two universities will ultimately sign the OA2020 Expression of Interest.

• The UFS and CUT Libraries are thankful to Mr Gareth O’Neill and UFS colleagues (Mr Charlie Molepo and Mrs Cornelle Scheltema-Van Wyk), who shared information with the attendees on transformation agreements (also referred to as Plan S) and AmeliCA, respectively. Plan S deals with transformation agreements to be signed with publishers, which are about negotiations with publishers to change from subscription-based to open-access journal publishing models. Mr Molepo and Mrs Scheltema-Van Wyk showcased the open access model that the UFS Library has already implemented, which is what AmeliCA is all about. This involves the publication of nine accredited UFS journals on the Open Journals System platform, which enhance its discoverability and accessibility. It was also a pleasure to listen to Prof Abdon Atangana from the UFS Institute for Groundwater Studies – a classic example of an activist and beneficiary of open access publishing – who was recently named as one of the top-10 cited researchers in the Web of Science, thanks to open access publication.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
