The University of the Free State (UFS) has joined The Conversation Africa (TCA) as a funding partner.  TCA, a not-for-profit media initiative, is part of a global platform that publishes articles written by academics and researchers.  The platform’s objective is to make the knowledge produced in the academy accessible, easy to understand, and freely available to the general public. Articles are published daily on the TC-Africa website - https://theconversation.com/africa. 

The platform uses a Creative Commons republishing model. This means articles can be republished by other media on the continent and internationally, ensuring even greater reach to audiences including academics, policy makers, funders, and the general public. 

To date, more than 55 UFS researchers and academics have published with TCA, and their articles have garnered more than 1,3 million readers globally. UFS researchers and academics are encouraged to publish with The Conversation. 

As part of the partnership, TCA will run writing workshops for UFS academics and researchers who want to enhance their writing and science communication skills. Dates for these will be announced soon.

How you can publish with The Conversation Africa

• Engage with The Conversation Africa editors when they contact you directly to write about your research area and expertise. The articles are short, ± 800 to 1 000 words.

• Pitch your idea for an article directly to The Conversation Africa here   

• Register as an author, and set up a profile

• Engage with the Communication and Research offices. Every week, The Conversation Africa sends an expert request for expert authors on topical issues to the Communication and Research offices, which can identify researchers. 
- Interested researchers are put into contact with the relevant editor at The Conversation to discuss the potential article

Why should you get published on The Conversation Africa?

Benefits for researchers and academics:

• Articles on the platform help to raise the profile of academics, often leading to policy engagement with governments, businesses, industry or professional bodies, conference invitations, academic collaborations, and further media exposure. 
• In the course of writing, academics get bespoke editorial assistance from the team working in consultation with them. 
• The opportunity to take part in a hands-on science communication writing workshop.
• Readership and republication metrics for each published article.
• A global readership with up to 1,2 million readers monthly.

Benefits for Communication and Marketing and the Research office:

• Provides well-curated, ready-to-use communication material for websites and social media. 
• Helps to profile the work of the university for marketing, communication, and awareness.
• Provides media exposure to the talent pool of UFS academics and researchers. 

Benefits for and across the university:

• Shines a spotlight on the excellent research and innovation at the UFS.
• Demonstrates the UFS’ commitment to facilitating greater engagement with society and promoting interdisciplinary communications.
• Visibility for the institution and researchers nationally and globally.
• Access to institutional analytics, including detailed data on the content published by UFS researchers.

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.
