Arne Geschke

Arne Geschke is an Associate Professor, researcher, and lecturer in the School of Physics within the Faculty of Science at the University of Sydney. He is affiliated with the Integrated Sustainability Analysis (ISA) research group. Geschke holds a PhD in Science from the University of Sydney, completed in 2013, and a Master of Education in 2020 from the same institution. His career trajectory at the University includes positions as a Postdoctoral Fellow and Academic Fellow in the ISA team, where he focused on global environmental assessment and input-output analysis. Prior to his academic roles, he worked as a mathematician. In 2022, he was recognized as a Highly Cited Researcher by Clarivate, placing him in the top 1 percent of researchers worldwide in the cross-field category covering environmental-economic assessment, renewable energy systems, sustainability, and biodiversity impacts.

Geschke's research specializations encompass input-output modeling, environmental-economic assessments, quantification of biodiversity and extinction-risk footprints from consumption and trade, supply chain analysis, global material flows, nitrogen and water pollution embedded in international trade, and socio-economic dimensions of environmental pressures such as those from tourism, pandemics, and health systems. He co-developed the Eora global multi-region input-output database at high country and sector resolution, a foundational tool for analyzing complex production networks and environmental impacts. Key publications include "The carbon footprint of global tourism" (Nature Climate Change, 2018), "Building Eora: a global multi-region input–output database at high country and sector resolution" (Economic Systems Research, 2013), "International trade drives biodiversity threats in developing nations" (Nature, 2012), "Mapping the structure of the world economy" (Environmental Science & Technology, 2012), "Decoupling global environmental pressure and economic growth: scenarios for energy use, materials use and carbon emissions" (Journal of Cleaner Production, 2016), "Substantial nitrogen pollution embedded in international trade" (Nature Geoscience, 2016), and "Global socio-economic losses and environmental gains from the Coronavirus pandemic" (PLoS ONE, 2020). These works have garnered thousands of citations and shaped understandings of trade-driven environmental degradation and pathways to sustainability. Additionally, Geschke teaches units on ecological economics and sustainability in the School of Physics and contributes to projects on supply chain resilience and actual land-based ecological footprints.
