Should the UFS continue to subscribe to academic journals that are behind a paywall?

On 12 May 2022, the University of the Free State (UFS) held an online seminar on Open Science, posing this question.

The seminar was facilitated by Prof Corli Witthuhn, Vice-Rector: Research and Internationalisation, who was joined by the following experts: Colleen Campbell from the Max Planck Digital Library (MPDL) in Munich, Germany, where she coordinates the Open Access 2020 Initiative; Ellen Tise, Senior Director of Library and Information Services at Stellenbosch University (SU); Glen Truran, Director of the South African National Library and Information Consortium (SANLiC); and Charlie Molepo, Deputy Director at the UFS Library Service. The discussion centred around the issues of accessing and publishing academic content behind a paywall, and what open access initiatives are doing to transition scholarly work to an open access (OA) paradigm.

“Publishing academic content behind a paywall not only limits access to scholarly work, but also prevents research output from being visible and making maximum impact,” the university stated.

Paywalls vs Open Access

A paywall is a figurative wall used to limit access to certain prestigious academic content. Overcoming this wall usually means a one-time purchase option where the reader buys the content from the publisher, or it could be subscription-based where you pay a subscription fee for a fixed period. OA, on the other hand, seeks to make any scholarly work freely available to anyone interested in accessing it, including those who cannot afford the subscription fees.

"Currently, authors are required to give up copyright of their research articles to publishers. We want to move to a fully open paradigm where authors can redeem and openly license their articles so that they are free to share, use, and reuse their work so that science can move forward faster. By making it open, we gain a wider possible readership that will help improve the quality of science,” Campbell said.

Furthermore, not only are publishers making a profit from subscription fees, but they also benefit significantly from hefty publishing and author fees.

“Researchers are paying to publish their research output, and libraries are paying to access it in what is known as double-dipping by publishers, leading to what we term ‘serial crisis’. Research institutions pay twice and still do not see their research widely available to be read.”

Transformative Agreements 

The panel explained the use of transformative agreements as a strategy to achieve full OA publishing. This strategy includes OA initiatives that organise investments around open research communication, demanding price transparency from publishers, as well as reorganising workflow and building up the capacity to make OA a default.

With Truran presenting statistics on OA in South Africa, he highlighted that “only 46% of South African journals are available freely, the rest are still out of reach of those who cannot afford to pay the costs associated with paywalls”. Tise touched on some negotiation principles for a transformational transition to OA. “Inclusivity and social justice must be core. Publishers must have an equity, diversity, and inclusion plan that addresses the challenges of researchers in the Global South.”

Should the UFS continue to subscribe to academic journals that are behind a paywall? 
Truran answered this question by saying: “If we’re going to cancel subscriptions, then we should do it in unity and at the appropriate time. At the same time giving transformative agreements a go."

In his closing remarks, Molepo clarified the university’s stance on OA: “The UFS has taken a decision to publish all our journals in-house. We have flipped from subscription to full OA, and in the process, have seen a huge improvement in terms of citation. The impact of those journals has improved drastically from 2015 to 2021. We are content with that. The route to OA is the route this university should be taking,” he said.

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.
