Arne Tobian’s research focuses on interactions among planetary boundaries
Tobian is working towards a joint PhD from Stockholm Resilience Centre and Potsdam Institute for Climate Impact Research (PIK), Germany. His PhD is part of the Earth Resilience in the Anthropocene (ERA) project. The ERA projects main objective is to improve the understanding of critical transitions shifting the Earth System out of the stable state. Tobian’s research aims at process-based quantifications of interactions among planetary boundaries, thereby investigating how increasing anthropogenic pressure on one aspect of the Earth system can contribute towards destabilizing others.
Tobian holds a Master of Science degree in Physical Geography and Ecosystem Science from Lund University, Sweden and a Bachelor’s degree in Geography from Leipzig University, Germany. He further followed courses at the Eötvös Loránd University, Hungary, the Universidad de Chile, Chile and the University Centre in Svalbard.
Before joining Stockholm Resilience Centre, Tobian was working as a research and teaching assistant within different subjects at Leipzig University and supported research at the Helmholtz Centre for Environmental Research (UFZ), Germany as well as the Jomo Kenyatta University of Agriculture and Technology, Kenya.

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...
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....
Towards a green water planetary boundary
Journal / article | 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...
