Prof Lesley Green
Prof Lesley Green was announced the winner of the 2023 ASSAf Humanities Book Award in the category ‘Established Researcher’. She delivered a lecture on her book: Rock. Water. Life: Ecology and Humanities for a Decolonial South Africa.

A group of more than 100 academics and students from universities across South Africa and abroad attended the virtual lecture by Prof Lesley Green, winner of the 2023 ASSAf Humanities Book Award in the category ‘Established Researcher’, who discussed her cross-cutting book, titled: Rock. Water. Life: Ecology and Humanities for a Decolonial South Africa. 

The lecture is part of a series focused on the Humanities Book Awards, offering award recipients a platform to discuss the motivation behind their books, the societal impact of their work, and the personal influences that shaped their text. Prof Reddy said that academics and students can anticipate a series of humanities book award lectures in the coming months. 

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation at the University of the Free State (UFS), member of the Academy of Science of South Africa (ASSAf), and member of the Book Award adjudication panel, facilitated the recent (29 August 2023) online 2023 ASSAf Humanities Book Award Lecture. 

Prof Green, Professor of Anthropology and the Director of Environmental Humanities South (EHS) at the University of Cape Town, was announced the winner of the 2023 ASSAf Humanities Book Award in the category ‘Established Researcher’, for which ASSAf received 31 nominations. She received the award at the end of March this year during a ceremony at the Vineyard Hotel in Cape Town.

The first ASSAf Book Prize was awarded in 2017, and since then ASSAf has conferred the award on an individual every two years to recognise and celebrate the significance and impact of well-written scholarly writings on human knowledge and intellectual efforts in South Africa. 

Prof Reddy characterised Prof Green's specific work as an outstanding book that makes a formidable contribution to the field.

Justice-based environmental sciences 

Prof Green’s research centres on justice-based environmental sciences in South Africa, with a particular focus on the relationship between knowledge and democracy in the Global South – a central theme in her award-winning text.

In the three parts of her book, ‘Past Present’, ‘Present Futures’, and ‘Futures Imperfect’, Prof Green explores the interwoven nature of the past, present, and future. Within these three parts, she delves into the fascinating array of identity markers, inequality, racism, colonialism, and environmental destruction in South Africa. 

Prof Reddy noted that the text asserts a need for environmental research and governance to evolve, contributing to addressing South Africa’s deep history of racial oppression and environmental exploitation. “The book also offers an in-depth engagement of environmental conflict, shedding light on matters often overshadowed by daily concerns in contemporary South Africa,” he added. 

The book, linking the humanities and social sciences with the natural sciences and applied sciences, touched on an array of important topics, including the history of contested water access in Cape Town, struggles over fracking in the Karoo, the call for the decolonisation of science (#ScienceMustFall), land restitution versus the politics of soil, contests over baboon management, and the consequences of sending sewage to urban oceans. 

Prof Green has observed the landscape of environmentalism for a couple of years and noticed a series of struggles. “Typically, these conflicts were being presented in highly polemic ways, often showcasing tremendous tension between academic environmentalism and activists on the ground. I noticed recurring patterns – what was being presented as the preferred form of environmentalism was not something I could support. For example, the frack-free Karoo campaign. It left me quite uncomfortable due to the erasure of Khoi and San presence in the Karoo,” she added. 

“So, what kind of environmentalism could I get behind? Questions around a just environmental governance begin to arise for me.”

Property, #ScienceMustFall, and black environmentalism 

During the discussion, Prof Green shared particular images from each section of her book that caused her to pause and reconsider her stance on the type of environmentalism she could support.

“We inherited a way of thinking about the world that was separated from nature and society. We have challenged that division of nature and society in respect of race and racism and sex and sexism, but we have not brought that critique to bear on how we relate to the world. Somehow, under neo-liberal governance, we find ourselves in this space where economics and finance are seen as the hero that will bring it all together. 

These comments merely scratched the surface of Prof Green’s insights into her book – which Prof John Higgins, Emeritus Professor who formerly held the Arderne Chair in Literature at the University of Cape Town (now Senior Research Scholar at UCT), referred to in his closing remarks as a rich description of a magnificent book. According to him, this scholarly book not only circulates and makes knowledge public, but also provides an opportunity to question that very knowledge. 

This marked the first instance where ASSAf combined book selection with a discussion on the chosen book, underscoring the value of scholarly literature.

- In the Emerging Researcher category, Dr Rick de Villiers from the UFS Department of English was a shortlisted candidate for his book, titled: Eliot and Beckett’s Low Modernism: Humility and Humiliation.

UFS venture cleans up acid mine drainage

The system that puts oxygen back into the water.

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
