Norberg works on theoretical and conceptual perspectives of complex adaptive systems applied to both biological and social systems. He does both modelling work using trait-based ecosystem models as well as linked social ecological systems using agent based models. Recent focus in the later topic is on learning processes and emergence and dynamics of norms.
Norberg has a background in biology and geology with focus on environmental and sustainability sciences. He got his PhD in systems ecology at Stockholm University. After a Postdoc at Princeton University with Professor Simon Levin he recieved an assistant research position at natural resource management at the Department of Systems Ecology, Stockholm University, which later transitioned to Stockholm Resilience Centre where he became a full Professor. He has been on one sabbatical with Professor Terry Hughes at James Cook University in Australia, and will be on a one year sabbatical at EAWAG in Zürich from mid-2019 to mid-2020 with Professor Francesco Pomati.
While Norberg's work mainly focusses on conceptual theory building, he also has a strong interest in building knowledge transfer and visualisation tools. He also represents the Stockholm Resilience Centre in the section for Biological Sciences at Stockholm University, and is a subject editor for the journal Ecology and Society.
Norberg is an appreciated teacher who currently leads the adaptive management module in the SRC Master's programme as well as Stockholm University’s online Master-level course “Introduction to Sustainability Science”.

There is growing concern over tipping points arising in ecosystems because of the crossing of environmental thresholds. Tipping points lead to abrupt and possibly irreversible shifts between alternative ecosystem states, potentially incurring high societal costs. Trait variation in populations is central to the biotic feedbacks that maintain alternative ecosystem states, as they govern the responses of populations to environme...

1. The role of trait trade -offs and environmental filtering in explaining the variability in functional traits and ecosystem processes has received considerable attention for vascular plants but less so for bryophytes. Thus, we do not know whether the same forces also shape the phenotypic variability of bryophytes. Here, we assess how environmental gradients and trade -offs shape functional traits and subse -quently ecosystem...

Changes to climate–carbon cycle feedbacks may significantly affect the Earth system’s response to greenhouse gas emissions. These feedbacks are usually analysed from numerical output of complex and arguably opaque Earth system models. Here, we construct a stylised global climate–carbon cycle model, test its output against comprehensive Earth system models, and investigate the strengths of its climate–carbon cycle feedbacks ...

As a consequence of global environmental change, management strategies that can deal with unexpected change in resource dynamics are becoming increasingly important. In this paper we undertake a novel approach to studying resource growth problems using a computational form of adaptive management to find optimal strategies for prevalent natural resource management dilemmas. We scrutinize adaptive management, or learning-by-doin...
