World Breastfeeding Week is celebrated every year from 1-7 August. In South Africa, it coincides with Women’s Month and gives us the opportunity to reflect on how far we have come and how far we still have to go to achieve gender equity in different spheres of life. Even more reason for us in the academic sphere to stop and think about the areas of support that may still need attention and effort to correct.

In the context of protecting breastfeeding this would speak to the Code of Good Conduct in the Labour Act which affords pregnant and breastfeeding women protection and support. In extreme cases it means protection from exposure to hazardous substances, but in the general setting of the work environment this relates to workplace support for a private and safe place to express breastmilk. One institution made headlines when a staff member was secretly videoed while she was expressing breastmilk. What is also needed is to put in place a policy that guides on how university property such as a fridge may or may not be used to store expressed breastmilk, or how to deal with a manager who insists on holding meetings in a woman’s scheduled milk-expressing time slots. The law may indicate that you are entitled to two 30-minute time slots to express but it is quite another issue to get your colleagues to accommodate or respect your biological needs.

Protecting breastfeeding 

Besides the protection of employees, the government in its commitment to improve child health and nutrition has committed to protect breastfeeding from the undue influence of the infant-formula industry by implementing the recommendations of the International Code for the Marketing of Breastmilk Substitutes. South Africa approved the Regulations Relating to Foodstuff for Infants and Young Children (R991) to control the marketing and promotion of infant formula by limiting how the product may be marketed and how the industry may engage with the public and child health and development professionals, in particular. 

While many are aware of the prohibition to advertise or to promote and distribute free or incentivised sales of infant formula, many may not be aware of the limitations placed on academics and researchers. The academic and research fraternity has had a long and conflicted relationship and history with the infant-formula industry. Many departments and individual researchers have received funding, conference sponsorship and gifts from the infant-formula industry. In the early 2000s at the height of the HIV epidemic, the Department of Health recommended that women living with HIV should not breastfeed and instead provided six months of free formula milk, inadvertently implying that health professionals approved of infant formula. While the national Department of Health has since stopped the distribution of free infant formula through the programme for the prevention of mother-to-child transmission of HIV (PMTCT) from 2011, many health professionals trained in the early years continue giving mixed messages to mothers and display limited skills to promote and support breastfeeding.

So how do we protect breastfeeding in the academic setting? 
As more women enter academia, managers and the institutional leadership need to be cognisant and purposeful in developing a breastfeeding culture by granting women the protections afforded them by the Labour Law. Furthermore, in all spheres of academia and research, and as an institution, we need to guard against conflict of interest and conflicted relationships with the infant-formula industry. We need to do due diligence by raising the awareness of R991. All child health and development professionals should be acquainted with R991 through their curricula, and we should individually and collectively be accountable in our conduct to protect, promote and support breastfeeding as a human right, an investment in health and development, and for a sustainable future. There can be no greater dividend than to invest in optimal nutrition for infants and our children. They are the future.

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.
