Dr Kgosi Mocwagae explored the Qwaqwa water crisis because at a young age, he could not understand why the community in which he grew up faced so many water challenges despite a high presence of water from rivers, consistent rainfall, and streams bursting from the ground.

Dr Kgosi Mocwagae, Programme Director and Lecturer: Department of Urban and Regional Planning, received his PhD qualification during the October virtual graduation ceremonies.

His study, titled Exploring the Qwaqwa water crisis for effective planning post-apartheid, focuses on the water crisis in the Qwaqwa area, which commenced on 1 January 2016 and saw people without access to clean drinking water from their taps. The community had to turn to alternative means, such as collecting water from government-contracted water tankers, rivers, emergency hydrants, and wells.

Understanding the water crisis

Dr Mocwagae says the reason why he took up this study was because at a young age, he could not understand why the community in which he grew up faced so many water challenges despite a high presence of water from rivers, consistent rainfall, and streams bursting from the ground.
 
In this study, he aimed to explore the history of water policy in South Africa, together with the water crisis in Qwaqwa. He also documented the lived experiences of the affected Qwaqwa communities to determine the effect of not having access to clean drinking water in terms of quality of water, time, money, and distance travelled, to name just a few. 

Dr Mocwagae furthermore assessed interventions by various actors during the Qwaqwa water crisis, which included accessing water from municipally contracted water tankers, streams and rivers, rainwater harvesting, donations, paying for delivery of water, boreholes, and emergency water hydrants intended for fire breakouts. He also investigated the implications of the Qwaqwa water crisis for effective planning in post-apartheid South Africa.

He states: “Despite reports from the government that the Qwaqwa water crisis was an issue from 2015 and a result of drought, the study proved differently.” 

Water crisis due to poor planning

“Firstly, the water crisis was a cumulative effect of poor water planning since the founding of Qwaqwa as a homeland in 1974. Further to this, Qwaqwa has not been able to sufficiently provide water to the community from 1974 to date.”

Dr Mocwagae continues: “A major contributing factor to the water crisis was that the three dams in the area were still performing their primary functions as established during apartheid. Planning would have to be done to reprioritise water to Qwaqwa.

He also found that the municipality had not planned and invested in the maintenance and development of water infrastructure to provide water. 

The study was also able to demonstrate that there is a form of socialisation in planning that does not prioritise the community of Qwaqwa. In this community, more than 50% of the people live in poverty. According to Dr Mocwagae’s findings, the idea exists that the community first needs to be viewed a worthy economic contributor in order for them to benefit from water that originates from Qwaqwa. 

“Alternative means of accessing water and water-use education are also needed as part of the process of resolving the Qwaqwa water crisis,” says Dr Mocwagae.

Plant scientists address wheat rust diseases at SASPP congress

In his research, Dr Botma Visser, researcher in the Department of Plant Sciences at the University of the Free State, highlighted the population dynamics of the stem rust fungus (Puccinia graminis f. sp. tritici) in Southern Africa. In recent years, two foreign stem rust races were introduced to South Africa, and a local virulence adaptation occurred in a third.

All of these races form part of the Ug99 group, a highly virulent collection of rust races endangering wheat production in many parts of the world. Despite the fact that half of the members of the Ug99 race group is prevalent in South Africa, Dr Visser’s work has clearly shown that Ug99 did not have its origin here. This emphasised the need to include neighbouring countries in the annual stem rust surveys, to proactively identify new races that could threaten local wheat production. In his research, Dr Visser also mentioned the way in which he has optimised modern molecular tools to accurately detect Ug99 isolates.

Dr Visser is one of three scientists from the Department of Plant Sciences that addressed delegates attending the biennial congress of the Southern African Society for Plant Pathology (SASPP) on the Bloemfontein Campus earlier this month on progress regarding research on wheat rust diseases conducted at the UFS.

Howard Castelyn, a PhD student in Plant Sciences, presented his research on quantifying fungal growth of the stem rust pathogen in wheat varieties displaying genetic resistance. This resistance, which is best expressed in adult plants, has the potential to remain durable in the presence of new rust variants. His presentation at the congress focused on optimising microscopic and molecular techniques to track fungal development in stem tissues of adult plants. These results now allow scientists to link rust infection levels and cellular responses with particular resistance genes expressed by the wheat plant, and contributing to the understanding and exploitation of durable resistance.

Prof Zakkie Pretorius presented his research, explaining how new genetic diversity for resistance to the stripe (yellow) rust fungus (Puccinia striiformis) is discovered, analysed and applied in South Africa. This research, conducted in collaboration with Dr Renée Prins and her team at CenGen, is unravelling the genetic basis of stripe rust resistance in a promising wheat line identified by Dr Willem Boshoff, a plant breeder at Pannar. The line and DNA markers to track the resistance genes will soon be introduced to South African wheat breeding programmes.

The rust research programme at the UFS contributes significantly to the successful control of these important crop diseases.

In addition to the contributions by the UFS, rust fungi featured prominently at the SASPP, with first reports of new diseases on sugar cane and Acacia and Eucalyptus trees in South Africa. A case study of the use of a rust fungus as a biological control agent for invasive plant species in the Western Cape, was also presented.
