Dr. Mohammad Zaman is working as a Soil Scientist/Plant Nutritionist covering countries in Africa, Asia, Middle East, Europe, Central and Latin America on mitigating greenhouse gas (GHG) emissions and developing climate smart agricultural practices for enhancing food production and minimizing land degradation and environmental sustainability using nuclear and related techniques. Prior to joining the SWMCN Section, he worked for 22 years in GHG mitigations, enhancing soil fertility and integrated plant nutrient management at different research, academic, commercial and international organizations in both developing and developed countries. Zaman is author and coauthor of one book, several book chapters and over 65 research publications in refereed journals. Zaman has won several awards for his professional achievements including the IAEA Superior Achievement Award in 2018, and the IAEA Best Technical Cooperation Award in 2018 and Lincoln University, Canterbury New Zealand Doctorate Scholarship in 1995. Christoph Müller, after an apprenticeship as a gardener (ornamental plants), Christoph studied Horticulture in Berlin, followed by a M.Sc. in Soil Water Management at Reading University and a Ph.D. in Soil Science at Lincoln University/New Zealand. Since 2007, he is Professor of Soil Science at University College Dublin and since 2009 Professor of Experimental Plant Ecology at the Justus Liebig University Gießen, where he is leading one of the worldwide longest running Free Air Carbon dioxide Enrichment (FACE) studies on grassland. His main research interest is to unravel the effects of climate change on ecosystems processes and in particular the processes of the climate relevant trace gases CO2, CH4 and N2O via novel stable isotope tracing methods. Christoph has published more than 200 peer-reviewed journal articles (h-index >41) and works as an expert for the International Atomic Energy Agency (IAEA) especially in the training of methods to quantify greenhouse gas emissions. He is married, and has two children, and when he is not doing science, he is interested in gardening and science history (e.g. collector of early Liebig trading cards).Lee Heng is working as a Section Head of Soil and Water Management & Crop Nutrition (SWMCN) Subprogram in the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. She has more than 27 years’ experience in soil-plant-water interactions, agricultural water management and water use efficiency, integrated nutrient water interactions, and diffuse pollution control for sustainable agricultural production systems, at both national and international levels. Her work is covering countries in Africa, Asia, Europe, and Central and Latin America on sustainable land and water management for climate smart agriculture and the efficient use and conservation of agricultural resources for enhancing food production and environmental sustainability.
