Dr Alexandre Köberle is an independent researcher focusing on long-term scenarios of socio-environmental change, with special focus on nexus approaches to explore transitions to alternative sustainable development futures. His interdisciplinary work uses mathematical models to develop plausible scenarios useful for stakeholders to not only enable the transition but also to identify risks and opportunities for improved human welfare and environmental sustainability. He is particularly interested in transformative systems approaches exploring nexuses across sectors and disciplines such as nature-food-finance or climate-land-energy-water and emerging trade-offs and synergies with sustainable and inclusive development objectives. Alex holds a multidisciplinary scientific background, including a DSc in Energy Planning from the Federal University of Rio de Janeiro (UFRJ; 2018), a MSc in Environmental Resource Management from Vrije Universiteit Amsterdam (2013) and a BSc in Plant Biology and Ecology from the University of California Davis (1994). Absent from academia between 1995 and 2012, he worked as a consultant for environmental organizations, a documentary filmmaker and musician, and ran his own company producing conferences and corporate events for Silicon Valley clients, including financial institutions. Seeing the absence of science-based sustainability in industry, he decided to return to academia in 2009 to work on policy relevant environmental research. Since receiving his MSc in 2013, he has worked at several leading research institutions in Europe working on transition scenarios and modelling to address the climate and nature loss crises, targeting the science-policy and science-business interface. After his doctorate, Alex spent five years as a Researcher at Imperial College London (ICL) after time at prestigious European institutions like the Netherlands Environmental Assessment Agency (PBL) and the International Institute for Applied Systems Analysis (IIASA). Currently, he is a Research Fellow at the Potsdam Institute for Climate Impact Research (PIK), an Honorary Senior Research Fellow at ICL, and a Guest Researcher at Instituto Dom Luiz (IDL) at the University of Lisbon. He also leads several independent research projects for private institutions and environmental organizations. He has a long history of working with integrated assessment models (IAMs) and transition scenarios, starting during his MSc internship and subsequent research at PBL, which developed during his doctorate at UFRJ with periodic stays at IIASA. As a Research Fellow at PIK working with the MAgPIE agriculture and land use modelling framework to explore food systems and nature-positive transition scenarios. He currently leads two projects, one aiming to inform measures to scale up Natural Climate Solutions (NCS) and the other to develop Food Systems Development Pathways (FSDP) at the global level and for three countries, of which he lead the Brazil country study. In 2020, he became a Senior Research Fellow at the Centre for Climate Finance and Investment (CCFI) at ICL Business School where he currently leads the research stream on Nature, Food and Biodiversity finance. He participated in several Horizon Framework projects, was a principal investigator on two projects funded by UK research councils to explore climate and nature finance (FlowCCA and FiNaClim-SD), and has designed and delivered several executive education courses on climate finance to financial institutions including the Singapore Green Finance Centre (SGFC). Since 2019, he contributed to the IPCC 6th Assessment Report as a Lead Author (LA) in WG3 Chapter 1 and Technical Summary and contributed to an inter-working group text box on effect of climate impacts on economic projections. In UNEP’s GEO6, he was a Lead Author in the two chapters assessing plausible futures towards sustainable development goals (SDGs).
