Agro-Environmental Systems (AES) Group

The AES research group seeks to improve our bio-geophysical understanding of the functioning of Agri-Environmental Systems.

The AES research group investigates the bio-geophysical functioning of Agri-Environmental Systems to better understand and manage the interactions of agriculture and natural resources under increasing societal demands and climate change. Our research underpins assessments related to crop production, agricultural nutrient and water use, and soil carbon management. We focus on robustly up-scaling field based crop models and trials to regional and global level with detailed representations of agricultural management. Combining insights from data and models, and novel representations of management, identification of bio-geophysical production constraints, and explorative research, allows us to identify feasible adaptation and mitigation options with the aim to design Agri-Environmental Systems that are more robust to climate change impacts while producing food more sustainable.

The AES group is using gridded global EPIC and GEPIC models coupled with the most recent and complete information on cropland and crop cultivation currently available globally to simulate global and regional crop production as well as agricultural impacts on the environment. The models are powered by a number of climate change and land-use scenarios, including RCPs, climate models, crop managements and adaptations.

AES has recently contributed to various international studies on climate and land-use change, including LC-IMPACT, CARBO-EXTREME, and IMPACT2C FP7 programs, and the AgMIP/GGCMI initiative that brings together an international community of crop modelers for climate impact assessment, model inter-comparison and improvement at the global scale.
