Tsietsi Ngobese, through the Wesolve4x Cleaning My Planet Campaign, motivated citizens to collectively fill over 23 000 refuse bags to date.

The mission: To collectively fill 20 million refuse bags every Saturday with the help of 20 million people who are cleaning their own communities and our planet for an hour. The message: My planet, my responsibility.

The mission and message that the Wesolve4x Cleaning My Planet Campaign wants to convey, is based on a simple premise: Get community members to donate one hour of their time to cleaning duties every Saturday for the next 20 years until 2039. At the same time provide a continuous educational programme about waste management to the general public and to schools in order to empower them to take responsibility.

Address trash blindness


Tsietsi Ngobese, Chief Executive Officer of this initiative and BSc Actuarial Science graduate, says he understands the transformative power of education and the role it plays in transforming diverse communities. Through outreach programmes in our community and schools, we are slowly eliminating generational trash blindness. We also tackle some of the social determinants of health by encouraging healthy living conditions within our communities through good waste management and recycling. 

It is important for Tsietsi to add value to society. He believes that the Wesolve4x Generation will transform the world for the better through education and empowering all citizens.

The campaign – officially endorsed by Miss Earth South Africa, Catherine Constantinides – was launched on the UFS Bloemfontein Campus as well as the Abram Hlope Primary School in Katlehong on 4 May 2019.

“We want to promote the benefits of a clean and healthy environment for future generations,” said Tsietsi. 

Since their inception, the group has collectively filled over 23 000 refuse bags with the help of active citizens. 

Challenge accepted

When former lecturer, Jan Blomerus, once challenged his Actuarial students to protect the environment in order to decrease the mortality rate (from natural disasters because of the effect of climate change), Tsietsi accepted the challenge. “By inspiring excellence and transforming lives, the UFS plays an important role; I started to believe that I can address societal challenges in the communities I am an integral part of,” he said.

When Tsietsi saw trash piling up everywhere and children playing at illegal dumping sites, he became concerned about the health risk to society. He believes the dumping area is contaminating the air and water around the dumping site. 

“I had to be part of the solution to start cleaning up, and most importantly, educating myself and others to continuously take responsibility for our own waste and change our thinking about littering. This is a generational issue and needs a generational approach to unlearn all habits of littering,” Tsietsi pointed out. 

As part of his vision, Tsietsi plans to reduce the waste taken to landfill sites and to increase that which is taken directly from households to recycling plants. He also wants to encourage people to find creative ways of converting what has previously been wasted into something useful. “This action can encourage individuals to generate an income from waste,” he said.

Take action

Tsietsi invites all members of the Mangaung community to get involved in the project. This is your opportunity to make a difference on Mandela Day. You can;
provide sponsorship for educational content on effective waste management, economic opportunities, and health issues to the general public and to schools;
provide refuse bags, plastic gloves or hand-washing soap (used by community members in every clean-up session);
join in a collective effort to clean your community by meeting at designated schools or any designated community assembly point on a Saturday (contact 011 307 2005 or info@wesolve4x.com for more information).

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.
