During the 77th General Assembly of the United Nations (UN), the plight of children of African descent was a main topic of conversation. The conversation was led by Dr Catherine Namakula, Senior Lecturer of Public Law at the University of the Free State (UFS) and Chairperson of the UN Working Group of Experts on People of African Descent (WGEPAD).

On Monday 31 October 2022, in New York, she presented the group’s yearly report, titled ‘Children of African Descent’ to the third committee of the General Assembly. Dr Namakula urged the UN and other stakeholders to avoid using photos of African children and children of African descent in deplorable situations for fundraising and marketing purposes. She stated that "children of African heritage are not synonymous with poverty".

Some of the issues discussed at the meeting included conflicts of law with regard to children of African descent, their disproportionate criminalisation, the intense policing of their families and homes, the racial conditioning of their education, and the use of images of them in degrading circumstances in UN and other stakeholder messaging for marketing and fundraising.

The Working Group recommended the creation of a racial justice index to assess how well states are performing and making progress in improving the well-being of children of African heritage. South Africa was one of the nations that intervened to affirm the report. Among the countries that affirmed other related issues were Russia, Cameroon, China, and Syria.

Dr Namakula also had private meetings with the leaders of the World Council of Churches, UN Women, UNICEF, and other UN agencies to talk about human rights-based approaches to programming aimed at mainstreaming racial justice in their work.

 

African Commission on Human and People’s Rights

In addition, Dr Namakula headed the WGEPAD team to the 73rd regular meeting of the African Commission on Human and People's Rights. She made a statement at the session that brought attention to the opportunities for and necessity of African civil society participation in the work of the Working Group and the UN anti-racism machinery. She made reference to the 'Declaration on People of African Descent' being drafted, to which they may add African perspectives.

Dr Namakula also called attention to the precarious status of victims of modern forms of enslavement, torture, and exploitation in the Middle East and Gulf States, emphasising the important role of civil society in documenting and publicising the tales of vulnerable victims. She emphasised the need for work on the reparations agenda to start right now in order to document Africa's claims and create the necessary institutional and normative frameworks.

She added that efforts are under way to have the UFS Faculty of Law serve as the academic alliance's anchor for the reparations agenda in Africa.

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.
