Zama Sithole, a master’s student in Environmental Managementat the University of the Free State (UFS), would one day like to assist communal artisanal small-scale miners (ASM) to legalise their work. Although the ASMs are not involved in turf wars or criminality as in the case of zama-zamas, they are deemed illegal workers.

The prime mining legislation, the Mineral and Petroleum Resources Development Act, makes no provision for subsistence or communal ASM activities. Such miners are therefore considered illegal miners.

“ASM employs more than 20 million people globally and a country such as South Africa, with an unemployment rate of 30,1%, should assimilate this type of mining as a legal form of employment,” says Zama.

“Their only client base is the surrounding communities. Mining, besides government grants, is their only source of income.”

Zama aspires to assist the illegal miners to become legal and reap the benefits of skills and funding to increase their income.

“And guidance from the regulatory authorities will ensure that the communal ASM miners become more aware of environmental management,” she adds.

Zama recently presented her research, titled: Shortcomings of the South African Legislative Framework in Addressing Communal Artisanal Small-scale Mining: A Blaauwbosch Case Studyat the 2020 Environmental Law Association (ELA) Annual Student Conference.

She also received the award for Best Speaker at the conference.

In her research, Zama focuses on Blaauwbosch, a rural township area located south-east of Newcastle in northern KwaZulu-Natal, where subsistence coal and clay opencast mining by community members has been going on for more than four decades.

Environmental degradation

According to the Mineral and Petroleum Resources Development Act, mining is only deemed legal if there is a mining permit, mining right, production right or preferent mining right authorised by the Department of Mineral Resources. Since communal ASMs are unregulated, environmental degradation is rife.

According to her investigation, environmental hazards such as traces of acid mine drainage and poor air quality (due to spontaneous combustion), are localised in the area. This is a deterrent to the surrounding community that has minimal health and safety awareness.

Owing to the fact that communal ASM miners are not assimilated into the legislation, the competent authorities such as the Department of Mineral Resources and Energy and the Department of Water and Sanitation cannot offer mineral regulation and environmental guidance support.

Losing revenue

Zama says government is also losing revenue by not legalising this unique sector. She believes it is important to differentiate between communal ASMs and the ‘zama-zama’ type of mining.
 
She also found that according to the Mining and Minerals Policy (1998), “regulations in respect of mining should be relevant, understandable and affordable to the small-scale miner and should be enforced in a site-specific manner.” ... “Tax and royalty rates, levies, and financial guarantees for rehabilitation should not constrain the development of small-scale operations.”

“However, to date, this has not been realised,” Zama states.

Communal ASM miners thus cannot benefit from government-funded initiatives to upskill them in terms of mining and environmental management.

Making a difference

Zama plans to conduct more research to understand the dynamics of how other countries have legalised this sector and draw learnings from this to determine how it can be applied in the South African context.

“In our country, there is very limited data and hence understanding on communal ASM. This could be one of the reasons why the government cannot make an informed decision on how to legalise this sector,” she says.

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.
