WomensMonth Art exhibition honours courageous South African women
Winnie Madikizela-Mandela became affectionately known as the ‘Mother of the Nation’. She passed away on 2 April 2018. Winnie Madikizela-Mandela by Alf Khumalo on display at the Oliewenhuis Art Gallery.

Art in its many forms has always challenged controversial issues in national and international discourse. The exhibition in commemoration of Women’s Day, titled Speaking out and standing up: An exhibition in honour of South African women, highlights women’s voices by narrating their own life histories. 

In collaboration with the Oliewenhuis Art Museum, the Centre for Gender and Africa Studies (CGAS) at the University of the Free State hosted an art exhibition on 1 August 2018. The exhibition took place on the same day as the national #TotalShutDown protests challenging gender-based violence and rape across South Africa. The exhibition included numerous South African female artists who have combined art and activism and was curated by Yolanda de Kock from Oliewenhuis. The works are on display at Oliewenhuis until 26 August 2018.

The historical representation of South African women

“Tonight’s exhibition focuses on the historical and contemporary representation of SA women, and one woman that deserves acknowledgement, is Winnie Madikizela-Mandela,” said Dr Nadine Lake, Gender Studies Programme Director at CGAS. She also highlighted the fact that “Madikizela-Mandela’s life attests to the multifaceted nature of black women’s lives. Her life reveals that black women are not automatically regarded as agents in their own right, but face discrimination, isolation, and exclusion when they step out of the parameters defined for them.” 

Dr Lake furthermore asserted that, “South African Women’s Month and Day is a reflection and commemoration of women’s achievements but is increasingly being criticised by feminists across the country. While the constitution enshrines the rights of women and prohibits discrimination, it has become clear that there is a huge disconnection between an aspirational ideology and women’s lived realities.” 

Women should lead their own narrative

Sharon Snell, Chief Executive Officer of the National Museum, said, “The dominant voice about Women’s Day is to spoil women and to give them flowers and chocolates on the day, in the same way as for Mother’s Day.” 

Women’s Day has unfortunately been equated to the traditional role that women play. The purpose of Women’s Day is to change those perceptions and to highlight issues of inequality. Snell said, “It is time for women to lead their own narrative.”

The exhibition highlights the important intersection between art and activism and focuses on aspects such as gender-based violence, homosexuality, corrective rape, domesticity and intersectionality, consumerism and feminism, traditional and family histories, women’s and children’s rights, identity and gender, bullying and domestic violence. Snell emphasised the fact that art has not been silenced and has carefully been articulating these important messages around gendered and social inequalities.

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.
