Profile summary

  • Ingo has a PhD in marine ecology from the University of Bremen/Alfred-Wegner Institute for Marine and Polar Research
  • Within the planetary boundary he investigates how
    controlling processes in whole
    earth systems interact
  • A major research aim is to trace planetary boundaries,
    test and compare different modeling approaches towards more detailed
    and spatially explicit models

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

Wang-Erlandsson, L., Tobian, A., van der Ent, R., Fetzer, I., te Wierik, S., Porkka, M., Staal, A., Jaramillo, F., Dahlmann, H., Singh, C., Greve, P., Gerten, D., Keys, P., Gleeson, T., Cornell, S., Steffen, W., Bai, X., Rockström, J. 2022. A planetary boundary for green water. Nature Reviews Earth and Environment. http://dx.doi.org/10.1038/s43017-022-00287-8

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

Singh, C., van der Ent, R., Wang‐Erlandsson, L., Fetzer, I. 2022. Hydroclimatic adaptation critical to the resilience of tropical forests. Global Change Biology. http://dx.doi.org/10.1111/gcb.16115

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

Chrysafi, A., Virkki, V., Jalava, M. et al. 2022. Quantifying Earth system interactions for sustainable food production via expert elicitation. Nature Sustainability. https://doi-org.ezproxy.its.uu.se/10.1038/s41893-022-00940-6

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....

The role of forests in securing water for agriculture globally

Journal / article | 2021

Pranindita, A., Teuling, A. J., Fetzer, I., and Wang-Erlandsson, L.: The role of forests in securing water for agriculture globally, EGU General Assembly 2021, online, 19–30 Apr 2021, EGU21-15766, https://doi.org/10.5194/egusphere-egu21-15766, 2021.

Forests worldwide supply moisture to downwind precipitation through moisture recycling. Agricultural areas located downwind of forests are, hence, susceptible to changes in precipitation caused by upwind forest changes. In fact, human activities have driven extensive forest cover changes in different parts of the world, in different directions, and at different rates. Nevertheless, the forest-agriculture relationship has yet t...
