Council for Geoscience (CGS)
The CGS is one of the National Science Councils of South Africa and is the legal
successor of the Geological Survey of South Africa. The strategic context within
which the CGS operates has been defined by a number of key factors, including its
legislative mandate and any changes thereof, the need to contribute towards Government’s
efforts to deal with the multitude of challenges it faces and strategies it
needs to implement, as well as the need for the CGS to contribute towards broader
regional and continental objectives in relation to geoscience.
The Geoscience Act, Act 100 of 1993, established the CGS in its present form. Today, the CGS is a modern institution, boasting excellent facilities and expertise, ranking among the best in Africa. The CGS is tasked with establishing a national investigative and application capacity which seeks to understand and produce knowledge about earth systems so as to bolster the nation’s ability to: manage its marine, land, water, energy and mineral resources; generate wealth through the identification and safeguarding of new mineral deposits, thereby contributing to the economic development of South Africa; contribute to the provision of comprehensive knowledge about the natural resource environments, their condition and hazard potential; and
promote the efficient and effective use of the environment and its natural resources.
The CGS is also committed to helping eradicate poverty by providing assistance to small scale mining projects, and plays a strategic role in the generation of geoscience knowledge in the Southern African Development Community (SADC) and on the African continent via the African Mining Partnership and proposed and a contribution towards the establishment of the Organisation of African Geological Surveys in order to foster partnership amongst geoscience institutions. The CGS also undertakes international projects and cooperates with a range of international geological and other organisations
Key persons involved:
Dr Henk Coetzee
Ph.D. in geophysics from the University of the Witwatersrand, Johannesburg.
21 years of experience in the application of various geophysical methods to a range
of exploration, geotechnical and environmental questions.
Major focus on the acquisition,
processing and interpretation of radiometric data, as well as most conventional ground and
airborne geophysical methods.
Some experience in remote sensing and image processing, with a focus on environmental issues related to mining, with a special focus on the combination of remotely sensed and geophysical information via geographical information systems (GIS).
The interpretation of environmental radioactivity data has also allowed him to gain some expertise in environmental geochemistry, with a focus on laboratory simulations of environmental processes and the use of naturally occurring isotopes as tracers.
He has also managed a number of large projects, including the South African Department of Minerals and
Energy’s Sustainable Development through Mining programme, looking in particular at regional strategies for the closure of gold mines in the Witwatersrand and the management of abandoned mines in South Africa.
Ms Danél van Tonder
Danél's main role in the project will be the environmental assessment of South African study area.
She holds a BSc Honours degree in geology from the University of Potchefstroom (now North
Has experience in geological mapping in granitic terranes, followed up by a strong background in mineralogy. She currently works in the Environmental Geoscience Unit at the Council for Geoscience where she is specialising in the environmental impact of mining with a specific focus on ecotoxicology.
She also has skills and experience in project management, having recently managed a project to develop regional mine closure strategies for the goldfields of the Witwatersrand on behalf of South Africa’s Department of Mineral Resources.
Mr Daniel Sebake
Daniel's role in the project will be remote sensing and GIS analysis.
Holds an M. Env. & Dev in Land Information Management, with 9 years experience in GIS and Remote Sensing applications.
In GIS he specialises in spatial databases, modelling and general data management.
In Remote Sensing, he is experienced in image preparation and processing, feature extraction, and image interpretations.
He took part as a researcher in national projects such as National Land Cover Project, Water usage estimation using remote sensing, and lately Sustainable Development through Mining as a field researcher and data analyst.
He has participated in international EO forums as a member of South African chapter of the Group on Earth Observation, Science and Technology thrust.
Mr Bantu Hanise
Will have the role of socio-economic and societal impact assessment.
Scientific Officer at Environmental Geoscience Unit (CGS) with a MPhil in Sustainable Development, Planning and Management from the University of Stellenbosch and have 7 years of experience in multidisciplinary research towards sustainability on resource management and development impacts.
Prior, he was involved with the South African National Antarctic Programs (SANAP) where he did two over-wintering expeditions on Marion Island in Sub-Antarctic Convergence.
He was part of the SANAP long-term monitoring biological/penguin and Climate Change Research.
Subsequently, He got involved in Water Resource Management research project of the Water Research Commission of South Africa.
His research explores sustainability and sustainable development methodologies through tools such as the Microsoft SuperCross program, participatory and systems thinking research approach towards Environmental Impact Assessment, Environmental Management Planning for the Small Scale Mining Program and urban development projects.
