Prof Klaus Kellner

Prof Dr Klaus Kellner is a C3 rated researcher (re-rated till end of 2022) by the National Research Foundation (NRF) in South Africa, in the field “Conservation and Management of Ecosystems and Biodiversity”.

He has been working at the North-West University for the last 27 years, as lecturer, mentor, supervisor and researcher and has supervised and co-supervised many post-graduate studies. His fields of expertise include vegetation dynamics, land degradation and desertification, restoration ecology and range condition assessment of mainly the arid- and semi-arid lands. The impacts of climate, different land-use strategies, loss in biodiversity, vegetation regression and anthropogenic factors, are used to identify indicators for the construction of simulation models for long-term decision making. The effects of implementing restoration strategies, especially after bush encroachment control are studied in the arid- and semi-arid Savannas.

Prof Kellner was or is the leader or PI (Principle Investigator) of several International projects carried out in Southern Africa, e.g. the Desert Margins Program (DMP), the Kalahari Namib Project (KNP), PRACTICE (Prevention and Restoration Actions to Combat Desertification. An Integrated Assessment), IDESSA (An Integrative Decision Support System for Sustainable Rangeland Management in southern African Savannas), etc. He contributes to three Chapters for IPBES deliverables (Intergovernmental Platform on Biodiversity and Ecosystem Services) and represents South Africa at the UNCCD-CST (Committee on Science and Technology of the United Nations Convention to Combat Desertification) and COP’s (Conference of Parties) for the UNCCD for the last 14 years. He is also a member of the National Coordinating Body (NCB) for UNCCD matters at the Department of Environmental Affairs (DEA) and leads research projects for the DEA and DAFF (Department of Agriculture, Forestry and Fisheries) in South Africa. He serves on different national and International committees regarding land degradation, desertification and restoration ecology and has done work for UNEP, the African Union (AU) and UNCCD regarding his field of expertise..

Prof Kellner served as Co-chair on the Advisory Group for the Provision of Scientific Advice (AGSA) on DLDD (Desertification, Land Degradation and Drought) matters for the UNCCD and is currently part of the SPI (Science and Policy Interface) committee for the UNCCD.

He is an honorary member of the Land Rehabilitation Society of Southern Africa (LaRSSA) (2014), was the president and chairperson of the Trust and now only a member of the GSSA (Grassland Society of South Africa), was the president of the Arid Zone Ecology Forum (AZEF) and is currently a member of the Society of Ecological Restoration (SER).

He has done many consultancies regarding advice about SLM and restoration at national and international level. In 2010 and 2015, he received the award as the “International Researcher of the year” from the North-West University for contributions in policy and advisory bodies, related societies and managerial level, international panels, subject related journals, conferences and organisations at national and global level. In 2007, he was selected as one of the top 10% and in 2009 and 2010 as one of the top 20% researchers at the North-West University in South Africa.
