Ingo Fetzer's research looks at how multiple stressors interact across global to local scales, and how they affect system stability, related to the planetary boundaries, global dynamics and -stability, and sustainable food production
He has strong interest in whole system processes and investigates the interaction of multiple stressors across scales - global to local - and their interactions on systems' stabilities. This includes identifying relevant factors, examination and visualization of large datasets, and investigation of system dynamics applying various statistical methods. He is also interested in how structural characteristics within systems help to maintain resilience and resistance towards disturbances with special emphasis understanding non-linear regime shifts and alternative stable states.
Within the planetary boundary research he intends to investigate how already identified and potential main controlling processes in whole earth systems interact and how disturbances on small temporal and spatial scales can result in emergent pattern on global scale or may create propagating effects on longer timescales. One of his major research aims is identify stable and desirable "just and safe operating space" for human beings, trace planetary boundaries, test and compare different modeling approaches towards more detailed and spatially explicit models.
Fetzer has a PhD in marine ecology (University of Bremen/Alfred-Wegner Institute for Marine and Polar Research) but recently also worked in the fields of microbiology, theoretical ecology, bioinformatics and ecological modeling. To study the dynamics of the biosphere in the Anthropocene, lately he expanded his research field, investigating planetary boundary issues applying the LPJmL Dynamic Global Vegetation Model.

A planetary boundary for green water
Journal / article | 2022
Green water — terrestrial precipitation, evaporation and soil moisture — is fundamental to Earth system dynamics and is now extensively perturbed by human pressures at continental to planetary scales. However, green water lacks explicit consideration in the existing planetary boundaries framework that demarcates a global safe operating space for humanity. In this Perspective, we propose a green water planetary boundary and es...
Hydroclimatic adaptation critical to the resilience of tropical forests
Journal / article | 2022
Forest and savanna ecosystems naturally exist as alternative stable states. The maximum capacity of these ecosystems to absorb perturbations without transitioning to the other alternative stable state is referred to as ‘resilience’. Previous studies have determined the resilience of terrestrial ecosystems to hydroclimatic changes predominantly based on space-for-time substitution. This substitution assumes that the contemporar...
Quantifying Earth system interactions for sustainable food production via expert elicitation
Journal / article | 2022
Several safe boundaries of critical Earth system processes have already been crossed due to human perturbations; not accounting for their interactions may further narrow the safe operating space for humanity. Using expert knowledge elicitation, we explored interactions among seven variables representing Earth system processes relevant to food production, identifying many interactions little explored in Earth system literature....
An Earth system law perspective on governing social-hydrological systems in the Anthropocene
Journal / article | 2021
The global hydrological cycle is characterized by complex interdependencies and self-regulating feedbacks that keep water in an ever-evolving state of flux at local, regional, and global levels. Increasingly, the scale of human impacts in the Anthropocene is altering the dynamics of this cycle, which presents additional challenges for water governance. “Earth system law” provides an important approach for addressing gaps in go...
