Dr. Katrin Drastig is the leader of the working group “Water Productivity in Agriculture (AgroHyd)” at the Leibniz Institute for Agricultural Engineering and Bioeconomy. She studied geology at TU Berlin, Germany, with a focus on hydrogeology, and here she was awarded her diploma. She was a research associate in the Department of Applied Geoscience at Justus Liebig University Giessen, Germany, and a PhD student, where she worked on the project “Waterbudget of Disturbed and Undisturbed Ecosystems” of the German Science Council headed by Prof. W. Wilcke at the University of Bayreuth in Germany and Ecuador. In addition, she has also worked at the Leibniz Institute for Agricultural Engineering at Potsdam-Bornim, Germany (ATB), in the Department of Technology Assessment and Substance Cycles, headed by Prof. Annette Prochnow (ATB, Humboldt-Universität zu Berlin, Germany). Also, she has worked as co-chair of the Technical Advisory Group (TAG) on Water Footprinting of the Livestock Environmental Assessment and Performance Partnership (LEAP) of the FAO. Her research interests include the following topics: process assessment under climate change conditions; assessment of technical and process adaptation demand; and agriculture water balances of single processes and whole branches as the basis for further development.
Dr.
Ranvir Singh is an Associate Professor in Environmental Hydrology and Soil
Science, and a Doctoral Supervisor at the School of Agriculture and
Environment, Massey University, Palmerston North, New Zealand. He specializes
in research and integration of field observations, geographical information and
hydrological models to study water use, irrigation and drainage systems,
attenuation of nutrient runoff and leaching from agricultural soils, and
surface water and groundwater hydrology in rural and peri-urban landscapes. Key
focuses of his research are on (a) advancing water quality science by mapping
and modelling of critical nutrients and sediments flow pathways,
spatially-variable nitrate attenuation (reduction) in shallow groundwaters, and
development of novel edge-of-field technologies (such as controlled drainage, woodchip bioreactors, and sediment traps) to
reduce runoff on nutrients from agricultural lands to receiving waters, and (b)
advancing water productivity and footprinting sciences by developing new
observations, methods, and models for both local and global contexts. He has
served as a member of ‘Grey Water Footprint Expert Panel 2012’, the Water
Footprint Network (The Netherlands and FAO Livestock Environmental Assessment
and Performance Partnership (LEAP) Water Technical Advisory Group (TAG)
(2016-2018).
