The University of the Free State is proud to announce the appointment of Nthabiseng Kotsokoane as chairperson of the International Federation of Library Associations and Institutions (IFLA) new Regional Council and member of the IFLA Governing Board 2021 – 2023.

IFLA is the leading international body representing the interests of library and information services and their users. It is the global voice of the library and information profession.

Nthabiseng Kotsokoane is currently the Assistant Director at the University of the Free State Library Information Services. She previously worked at Monash University for 10 years as a director of the library services. Ms Kotsokoane is a renowned library professional whose passionate efforts to advance library and information services in Africa and beyond are widely acknowledged. She has vast experience in serving at various committees regionally and internationally. She served as a member of the IFLA women information Libraries Special Interest Group. She was later elected by LIASA into the IFLA IT committee. She is the current IFLA Africa section Chair 2017-2021.

 

Serving the international library community

Nthabiseng is not only active in IFLA but on the African continent as well, she is the past chair for the African Library & Information Associations & Institutions (AfLIA) academic library section Chair and a member of the AfLIA Governing Board.

As IFLA’s Regional Chair her key role will be to in increase the presence of world regions in IFLA and IFLA’s presence around the world focusing on advocacy and building capacity. She will lead efforts to provide input on IFLA advocacy work and review success in developing the regional dimension of the IFLA Strategy, as well as work to promote IFLA membership and fundraising in the regions.

This will include coordination and development of Regional Division action plans, review Regional Division activities in the following regions Regional Council and Regional Divisions for Asia and Oceania, Europe, Latin America and the Caribbean, Middle East and North Africa, North America and Sub-Saharan Africa. With her passion of developing and mentoring new library professionals we are certain that this new role will be of benefit to the international library community.

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.
