Singer, writer, and motivational speaker, Melissa de Aveiro, says: “One can only rise from the ashes when the fire starts again, and the beauty of it all is that the ashes is stuck to your clothes. As you move on, you build off it as it falls from your clothes.”

She said: “When the fire starts in you, nothing is going to stop it.”

This she said at the Division of Organisational Development and Employee Well-being’s Rising from the Ashes event held at the Centenary Complex on the Bloemfontein Campus. Melissa’s story is about never giving up and “never backing down – even when people throw you with rocks, use the rocks to build a new road”.

Melissa said: “Many people unfortunately do not rise from the ashes because there is no support from friends, people. You can never do it alone as the journey through the ashes is lonely.”

Melissa believes to get through the ashes, one has to go back and “remind yourself of when it was good in your life, remind yourself about the positive things – even though things might not be great now”.

Known as the 'Weskus Dutchess', and growing up in Vredendal, Western Cape, Melissa’s tough life, sexual abuse, drug abuse, homelessness, and the death of her son never stopped her from dreaming. All the setbacks planted in her a “passion for a guitar and people, a birth of a new season, a desire to change the world”.

To rise from the ashes, Melissa said, “You need to go back to the place where you were hurting, confront the demons, the people that abused you, maybe forgive them and remove the chains you are tied with.”

Susan van Jaarsveld, Senior Director: Human Resources at the University of the Free State, believes that hosting wellness events is a way for the UFS to show that “employees are the most valuable asset of the university and need to be looked after”.

Susan said: “Staff need to know that it is okay not to be okay. However, the UFS has systems to look after your well-being. People need to know that they are not alone, they can make use of the Department of Human Resources’ Careways Employee Wellness Programme.”

Susan believes it was important to host the event, as “staff need face-to-face interaction for their well-being, it helps people to know they are not alone”.

Melissa, the author of the book Weskus Wonderwerk, believes in being unstoppable. She said: “To rise from the trenches, always think positive about yourself, you must exist. You cannot give up; your worth cannot be determined by an individual.”

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.
