Constantino, S., Schlüter, M., Weber, E., Wijermans, N.. 2021. Cognition and behavior in context: a framework and theories to explain natural resource use decisions in social-ecological systems. Sustainability Science. http://dx.doi.org/10.1007/s11625-021-00989-w
The complex, context-dependent, and dynamic nature of human behavior is increasingly recognized as both an important cause of sustainability problems and potential leverage for their solution. Human beings are diverse, as are the social, ecological, and institutional settings in which they are embedded. Despite this recognition and extensive knowledge about human decision-making in the behavioral sciences, empirical analysis,...

Social simulation targets social science problems and challenges, of theoretical, empirical and applied nature, using simulation. This implies contributing to the development of theory/explanations of social phenomena or using existing theories and models to understand or predict outcomes of social processes. The different uses of social simulation and the different roles it can play in the research process make it the Swiss a...

A key challenge in social simulation is how to represent human behavior, specifically in its social context. The Social Identity approach (SIA) reflects a promising potential as it describes how people behave while being part of a group, how groups interact and how these interactions and ‘appropriate group behaviors’ can change over time. SIA is used in a variety of fields and increasingly implemented in agent-based models. A...
Verhagen, H., Borit, M., Bravo, G. and Wijermans, N., 2020. Advances in Social Simulation.
Since the first larger scale conferences in the early 1990s, social simulation has rapidly evolved into becoming a methodology known by researchers and practitioners in different areas including sociology, political science, economics, history, and ecology, to name a few. Each of these disciplines has to address what sociologists call the micro-macro link – how individual decision-making entities interact to produce effects at...

Wijermans, N. and O’Neill, E.D., 2020. Towards Modelling Interventions in Small-Scale Fisheries. In Advances in Social Simulation (pp. 485-489). Springer, Cham.
Interventions often have unintended effects, particularly when they target outcomes in complex social-ecological systems (SES), such as fisheries. Development agencies strive for ‘doing development differently’, because past efforts have often been unsuccessful. The question then is how to do better. Science can make a major contribution here. Its power lies in synthesising and generalising knowledge embedded in ‘thinking tool...
Wijermans, N., W. J. Boonstra, K. Orach, J. Hentati-Sundberg, and M. Schlüter. 2020. Behavioural diversity in fishing—Towards a next generation of fishery models. Fish and Fisheries 00:1–19.
Despite improved knowledge and stricter regulations, numerous fish stocks remain overharvested. Previous research has shown that fisheries management may fail when the models and assessments used to inform management are based on unrealistic assumptions regarding fishers' decision‐making and responses to policies. Improving the understanding of fisher behaviour requires addressing its diversity and complexity through the integ...
Lindkvist, E., Wijermans, N., Daw, T.M., Gonzalez-Mon, B., et.al. 2020. Navigating Complexities: Agent-Based Modeling to Support Research, Governance, and Management in Small-Scale Fisheries. Front. Mar. Sci., 17 January 2020, https://doi.org/10.3389/fmars.2019.00733
The sustainable governance and management of small-scale fisheries (SSF) is challenging, largely due to their dynamic and complex nature. Agent-based modeling (ABM) is a computational modeling approach that can account for the dynamism and complexity in SSF by modeling entities as individual agents with different characteristics and behavior, and simulate how their interactions can give rise to emergent phenomena, such as over...

Schlüter, M., Orach, K., Lindkvist, E., Martin, R., Wijermans, N. et al. 2019. Toward a methodology for explaining and theorizing about social-ecological phenomena. Current Opinion in Environmental Sustainability Volume 39, August 2019, Pages 44-53
Explanations that account for complex causation, emergence, and social-ecological interdependence are necessary for building theories of social-ecological phenomena. Social-ecological systems (SES) research has accumulated rich empirical understanding of SES; however, integration of this knowledge toward contextualized generalizations, or middle-range theories, remains challenging. We discuss the potential of an iterative and ...
Schlüter, M., L. J. Haider, S. J. Lade, E. Lindkvist, R. Martin, K. Orach, N. Wijermans, and C. Folke. 2019. Capturing emergent phenomena in social-ecological systems: an analytical framework. Ecology and Society 24(3):11.https://doi.org/10.5751/ES-11012-240311
Social-ecological systems (SES) are complex adaptive systems. Social-ecological system phenomena, such as regime shifts, transformations, or traps, emerge from interactions among and between human and nonhuman entities within and across scales. Analyses of SES phenomena thus require approaches that can account for (1) the intertwinedness of social and ecological processes and (2) the ways they jointly give rise to emergent so...
Waldherr, A., N. Wijermans. 2017. Modelling the role of social media at street protests. In Wander J., R. Verbrugge, A. Flache, G. de Roo, L. Hoogduin, C. Hemelrijk. Advances in Social Simulation 2015 528: 445-449.
Occupy, the Gezi park movement, the Maidan protests, or the recent solidarity marches for Charlie Hebdo—since the uprisings of the Arab Spring, we could observe many examples of on-site protests on big squares and streets being accompanied by waves of collective action in social media. We present the design stage of an agent-based model that will allow us to explore the following questions: What role does social media play in ...
