The new book that Dr Tshepo Moloi has co-edited puts a spotlight on liberation struggle radios.

Dr Tshepo Moloi from the Qwaqwa Campus Department of History is the co-editor of a new book called Guerrilla Radios in Southern Africa: Broadcasters, Technology, Propaganda Wars, and the Armed Struggle.
This book is a collection of eleven essays on the histories of the radios attached to the armed wings of the liberation movements in the region. “This book is a shift from a parochial approach, which tended to analyse guerrilla radios within the framework of the nation state. It focuses on the experiences of the broadcasters and listeners during the era of the armed struggle. Using archival sources such as sound recordings of the guerrilla radio stations, together with interviews conducted with former broadcasters and listeners, the essays contained in this volume ask complex questions about the social histories of these stations,” said Dr Moloi.
Dr Moloi added that the essays explore the workings of propaganda and counter-propaganda and probe the effects that the radios had on the activists and supporters of the liberation movements – and, on the other hand, on the colonial counter-insurgency projects. They examine the relationships that these radios have forged at their multiple sites of operation in host countries, and also look at international solidarity and support, specifically for radio broadcasting initiatives. 
Role played by guerrilla radio
“Our volume pushes the frontiers of knowledge production beyond exploration of broadcast content towards a more nuanced conception of radio as a medium formed by social and political processes. Guerrilla radio broadcasting, we argue, became a very powerful technology for disseminating insurgent propaganda messages of the liberation movements and for mobilising African workers, peasants, students and youth in the struggle against white minority domination in the entire region. From Angola to Mozambique, and from Zimbabwe to Namibia through to South Africa, the modern technology of radio has provided the liberation movements in exile with a platform for an aural or sonic presence among the followers of the liberation movements back home. It has become an effective instrument for propagating the ideologies of the liberation movements, as well as for countering the propaganda messages of the oppressive white minority regimes,” he added.
Conceptualisation of the book
He also revealed the thinking behind the book. “The concept arose from the realisation that despite the explosion of research on liberation struggles in Southern Africa, such as memoirs, biographies, and autobiographies of prominent leaders of the movements, as well as a scattering of (auto)biographies of the foot soldiers, there remained a dearth of studies on the media that the liberation movements employed, particularly radio.”
Other editors are Sekibakiba Peter Lekgoathi, a professor of History at Wits University and Prof Alda Romão Saúte Saíde from Pedagogic University in Maputo, Mozambique. The project was funded by the National Institute for the Humanities and Social Sciences’ (NIHSS) Catalytic Research Project.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
