Our goal is to conduct research and research-oriented training to further the understanding of the functioning of major tropical plant production systems in a changing environment. Environmental changes comprise the big challenges agricultural systems are increasingly facing in the future in the different regions in the tropics and sub-tropics: water scarcity, soil nutrient depletion, soil loss, more severe adverse weather events, enhanced ozone concentrations and climate change. Last, but not least, in collaboration with other disciplines we conduct quantitative research on the various dimensions of food security at different scales.
