Gender inequalities domestic violence and gender-based violence (GBV) are global concerns, and have been exacerbated by the impact of Covid-19 as women take on more child and care work responsibilities.  Jobs lost in service sectors often affect women most, large numbers of frontline health workers and teachers are women, and lockdowns increase domestic violence. Thus President Cyril Ramaphosa recently said in a televised address that more than 21 women and children have been murdered in South Africa within just a few weeks in what he referred to as “another pandemic raging in our country.” He said this “violence being unleashed on women and children with a brutality that defies comprehension, is no less than a war being waged against the women and children of our country”.

As the World Economic Forum points out, regardless of where one looks, it is women who bear most of the responsibility for holding societies together, be it at home, in health care, at school, or in caring for the elderly. In many countries, women perform these tasks without pay. 

Now, the Covid-19 pandemic is compounding existing gender inequalities, and increasing risks of gender-based violence. Gender inequality, layered along with the effects of the pandemic, lockdowns and the economic downturn, could leave a deep and lasting impact on the lives and opportunities of women and girls.

Given, then, that the COVID-19 crisis affects women and girls in different ways from men and boys, measures to resolve it must take gender into account, and the protection and promotion of the rights of women and girls prioritized. 
To take up these issues of gender inequalities and gender-based violence, two renowned gender research experts will take part in our webinar. The webinar will be chaired by Professor Melanie Walker of the University of the Free State.  The presenters are: Professor Pumla Gqola, Professor of Women and Gender Studies at Nelson Mandela University and author of Rape: A South African Nightmare. Lisa Vetten has worked in the field of violence against women for over two decades as a counsellor, para-legal, trainer and researcher. She is currently an honorary research associate at the Wits Institute for Social and Economic Research (WiSER).

Join us from 14:00 to 15:30 on 28 July. 

RSVP to Sibongile Mlotya at MlotyaS@ufs.ac.za no later than 26 July, upon which you will receive a Business for Skype meeting invite.

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.
