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.

Moisture recycling and the potential role of forests as moisture source during European heatwaves

Journal / article | 2021

Pranindita, A., Wang-Erlandsson, L., Fetzer, I., Teuling, A.. 2021. Moisture recycling and the potential role of forests as moisture source during European heatwaves. Climate Dynamics. http://dx.doi.org/10.1007/s00382-021-05921-7

Heatwaves are extreme weather events that have become more frequent and intense in Europe over the past decades. Heatwaves are often coupled to droughts. The combination of them lead to severe ecological and socio-economic impacts. Heatwaves can self-amplify through internal climatic feedback that reduces local precipitation. Understanding the terrestrial sources of local precipitation during heatwaves might help identify mit...

Towards a green water planetary boundary

Journal / article | 2021

Wang-Erlandsson, L., van der Ent, R., Staal, A., Porkka, M., Tobian, A., te Wierik, S., Fetzer, I., Singh, C., Jaramillo, F., Greve, P., Gerten, D., Keys, P., Dahlmann, H., Gleeson, T., Steffen, W., Cornell, S., and Rockström, J. 2021. Towards a green water planetary boundary, EGU General Assembly 2021, online, 19–30 Apr 2021, EGU21-13583, https://doi.org/10.5194/egusphere-egu21-13583, 2021.

Green water - soil moisture, evaporation, and precipitation over land - is fundamental to safeguard Earth system functioning. Nonlinear green-water driven changes in climate, ecosystems, biogeochemistry, and hydrology are becoming increasingly evident and widespread. Yet, considerations of continental to planetary scale green-water dynamics are yet to be assessed and incorporated in management and governance. Here, we propose...

Illuminating water cycle modifications and Earth system resilience in the Anthropocene

Journal / article | 2020

Gleeson, T., Wang‐Erlandsson, L., Porkka, M., Zipper, S.C., Jaramillo, F., Gerten, D., Fetzer, I., Cornell, S.E., Piemontese, L., Gordon, L.J. and Rockström, J., 2020. Illuminating water cycle modifications and Earth System resilience in the Anthropocene. Water Resources Research, 56(4), p.e2019WR024957

Fresh water—the bloodstream of the biosphere—is at the center of the planetary drama of the Anthropocene. Water fluxes and stores regulate the Earth's climate and are essential for thriving aquatic and terrestrial ecosystems, as well as water, food, and energy security. But the water cycle is also being modified by humans at an unprecedented scale and rate. A holistic understanding of freshwater's role for Earth system resilie...

Keystone Species and Modularity in Microbial Hydrocarbon Degradation Uncovered by Network Analysis and Association Rule Mining

Journal / article | 2020

Centler, F., Günnigmann, S., Fetzer, I. and Wendeberg, A., 2020. Keystone Species and Modularity in Microbial Hydrocarbon Degradation Uncovered by Network Analysis and Association Rule Mining. Microorganisms, 8(2), p.190.

Natural microbial communities in soils are highly diverse, allowing for rich networks of microbial interactions to unfold. Identifying key players in these networks is difficult as the distribution of microbial diversity at the local scale is typically non-uniform, and is the outcome of both abiotic environmental factors and microbial interactions. Here, using spatially resolved microbial presence-absence data along an aquife...
