Dr. Graham P. von Maltitz is a systems ecologist, land degradation and rural development specialist. He has over 30 years of experience in environmental research with a focus on African ecosystems. Following a 30-year career at the CSIR, he is currently an associate of the School of Climate Studies, Stellenbosch University, South Africa. He has engaged at the Science-Policy interfaces at both the national and international level. This includes being a coordinating lead author and lead author on the IPBES Land Degradation and Restoration (LDR) and Africa assessments respectively. He is the Africa representative of the United Nations Convention to Combat Desertification (UNCCD) Science-Policy Interface (SPI). His research interests focus on sustainable land management in response to global change. Prof. Dr. Guy Midgley is Distinguished Professor in Botany and Zoology, Stellenbosch University, South Africa. He has focusedover four decades on applied ecophysiology, population, and ecosystem level approaches to advance understanding of the risks of climate change to the functioning and biodiversity of austral ecosystems, with a particular focus on biodiversity hotspots. Highly cited work includes that on species extinction risk under climate change, the global role of wildfire in controlling ecosystem structure, and the role of past and future CO2 levels on ecosystem structure and function. He was a co-ordinating lead author for the IPCC 4th and 5th and lead author on the 6th assessment report, and for the Global Report of the Intergovernmental Platform for Biodiversity and Ecosystem Services. He is a recent awardee of the Royal Society Marloth Medal for contributions to science and policy, and a Humboldt Foundation Research Awardee for lifetime contributions to science.Dr. Jennifer Veitch is a physical oceanographer and numerical modeller at the Marine Offshore Node ofthe South African Environmental Observation Netwok. Her particular area of expertise is the Benguela upwelling system, from the Angola-Benguela Frotal Zone at its northern boundary to the Goodhope Jet at its southern. More generally, she uses models to understand, and provide information on, the interacting roles of ocean and atmosphere at various scales. Presently, she is lead of the Sustainable Ocean Modelling Initiative: a South African Approach (SOMISANA) project whose vision is to provide accurate information about the changing state of the ocean for enhanced societal impact. Dr. Christian Brümmer is a research scientist at Thünen Institute of Climate-Smart Agriculture in Braunschweig, Germany. He leads the working group “Micrometeorological Measurement Techniques” and is the National Focal Point of the Integrated Carbon Observation System (ICOS) Germany. He holds a PhD in Biometeorology from University of Freiburg. He has conducted numerous field campaigns in various ecosystems in Europe, North America and Africa to investigate the biosphere-atmosphere exchange of greenhouse gases and air pollutants. His research focusses on the further development of a methodology for continuous observation of reactive nitrogen compounds. He is an Associate Editor of the journal “Atmospheric Measurement Techniques”.Prof. Dr. Reimund P. Rötter holds the Chair of Tropical Plant Production and Agricultural Systems Modelling (TROPAGS) and is a member of the Center of Biodiversity and Sustainable Land Use (CBL) at the Georg-August-University of Göttingen. He is an agronomist, agrosystems modeller and agro-ecologist with 30 years' work experience in Europe, Africa and Asia. His research interests lie in understanding and finding solutions for the multi-facetted challenges of achieving food security in a changing climate under increasingly limited resource availability. He is senior editor of the journal “Food Security”, Associate Editor of “Frontiers in Agronomy”, and has been an editor for various books including a Springer book. Reimund has been a lead author for the IPCC, Working Group II.Prof. Dr. Finn A. Viehberg is a senior research scientist at the University of Greifswald and private lecturer at the University of Cologne. He is engaged in multidisciplinary projects to understand the dynamic succession and interplay in the water-land-ecosystem nexus, in the spotlight of climate change and anthropogenic forcing, on both short and longer timescales. He is a palaeolimnologist, who conducted research in ponds of the Canadian Arctic to South African lagoons and Subantarctic fjords.Dr. Maik Veste is a senior researcher for environment and sustainability at the CEBra – Centre for Energy Technology Brandenburg e.V. in Cottbus, Germany, and lecturer for plant ecology/ecophysiology at the Institute of Environmental Science of BTU Cottbus-Senftenberg. He studied biology at the Westfälische Wilhelms-University of Münster and received his PhD in Plant Ecophysiology from the University of Hohenheim. He has more than 30 years of work experiments in applied ecology and conducted various long-term ecological research expeditions in the drylands of South Africa, Namibia, Israel, and northern Africa. His research fields include ecophysiology, soil-plant ecology, plant biogeochemistry, biological soil crusts and plant-climate interactions at various scales to understand the functions of vegetation in the biogeosphere. He is the editor of various Springer books.
