Restore Kalahari

17 March 2023 – Namakwari Lodge, Kathu, Northern Cape

The Kalahari is known as a mining hub with more than thirty mines in the southern Kalahari. This seminar investigates how the Kalahari can be a leading restoration area within the context of industry trends, Kalahari research and recent legislation promulgated to effect this vision.


The southern Kalahari is home to significant expansion and development as a result of productive mining since the 1950s. Transformation of the Kalahari is extensive, due to the intergenerational cumulation of mining, further escalated by higher urban populations and more recent solar energy developments.

Rehabilitation work in the Kalahari commenced in the 1980s, as published in the seminal work by Dr S. Wyk (van Wyk, Stephanus. 1994. ‘n Strategie vir die rehabilitasie van versteurde mynbougebiede in Suidelike Afrika. Potchefstroom: University of Potchefstroom).

The changing and more demanding legislation and increasing rehabilitation costs to meet mine closure obligations require a greater understanding. Arid areas consist of complex interactions, providing real challenges to define a workable system that can be used for rehabilitation success.

The Kalahari mining and construction industries have tremendous resources to solve the above challenges, but isolated efforts need to be consolidated and knowledge shared to ensure that success is increased, duplication of trials reduced, and resources applied sensibly to effect landscape changes in the long term.

The objective of this seminar is to bring Kalahari industry leaders together to engage in a seminar and solution exchange for area-specific rehabilitation. It is aimed at Kalahari leaders and service providers who want to understand and overcome the closure and rehabilitation challenges we face.
