Jonna van Opstal

Senior Water Productivity Expert


Jonna van Opstal (Ph.D.) holds a degree in irrigation engineering and water management. During her doctoral research at Utah State University she focused on evaluating irrigation district performance using field measurements (irrigation evaluations, flux towers), energy balance modelling, and irrigation simulation modelling. Recent major international projects she managed and executed, focus on crop water productivity analysis using open access spatial data. These were both research and capacity building projects in various countries mainly on the African continent and the Middle East. Her ambition is to enhance interactions between science and practitioners in the field of agricultural water management, using innovative spatial analysis tools.
