Dr Lazlo Passemiers spent six years conducting research across three continents.

A keen interest in unravelling transnational histories of 20th-century Southern Africa led Postdoctoral Research Fellow Dr Lazlo Passemiers to spend six years conducting extensive research across three continents. Dr Passemiers sifted through archives in Africa, Europe, and the US in order to convert his PhD thesis into a monograph.

It was on 17 July 2019 that the fruits of Passemiers’ labour were officially launched by the International Studies Group at the University of the Free State’s Bloemfontein Campus. His book, Decolonisation and Regional Geopolitics: South Africa and the ‘Congo Crisis’, 1960-1965, offers an important shift in the historiography of the Congo Crisis. It creatively centres African involvement in the debate by examining this event from a regional geopolitical angle. 

Going back in time 

By providing a three-fold perspective that examines decolonisation, apartheid diplomacy, and Southern African nationalist movements, the book offers a rounded picture of South African involvement in the Congo Crisis.

Dr Passemiers’ fascination with the transnational dynamics of Southern Africa’s history has rippled into two new research projects that respectively explore “the connection between decolonisation and white flight in the region as well as the transnational support networks of liberation movements”.

Finding the missing pieces of the puzzle

Prof Christopher Saunders, Emeritus Professor at the University of Cape Town, commended Dr Passemiers’ historiographical contribution: “He has identified a major gap in the literature and he has filled it admirably by looking across the spectrum.” As Prof Saunders noted, “what has been missing in the literature is the African angle.” 

Literature’s role in transformation

The process of undoing the profound impact of colonialism on society is long and difficult and important in this process is a clear understanding of history, which Dr Passemiers’ book enhances.

Plant-strengthening agent enhances natural ability of plants to survive
2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic conditions).

Most wild plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as it does not induce unwanted early vegetative growth that could jeopardise the final yield ? as happened in the past for nitrogen application at an early growth stage.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
