Dr. Amit Kumar Srivastava holds PhD in Agriculture Science with background in Crop and Cropping systems modelling, Agronomy, Forestry, and Agri-business-Management. He is  having experience of 11+ years as a postdoctoral researcher in Italy and in Germany with focus on Climate change impact on crop production; agricultural land use and food security; cropping system processes and responses to the management and climate; crop yield forecasting and Machine learning. He is currently working as a research scientist in the Institute of Crop Science and Resource Conservation, University of Bonn, and involved in agro-ecological modelling framework development (SIMPLACE) in connection with Upscaling Site-Specific Climate-Smart Agriculture and Land-use practices to improve regional production systems via integrated farm-system model development. He is also actively involved in the Agricultural Model Intercomparison and Improvement Project (AgMIP), an international, transdisciplinary project connecting climate science, crop modelling, and economic modelling to place regional agricultural impacts of climate change into their global economic context to assess uncertainties and vulnerability of world food security.
