Marcus Alexander "Marco" Janssen (born 1969) is a Dutch American econometrician and Professor at the Arizona State University and Director of its Center for Behavior, Institutions, and the Environment. He is known for his work on the modelling of socio-ecological systems. [1] [2]
Janssen was born in Hendrik-Ido-Ambacht. Janssen obtained his MA in Econometrics and Operations Research at the Erasmus University Rotterdam in 1992. He received his PhD in Mathematics at the Maastricht University in 1996 under supervision of J. Rotmans and O.J. Vrieze with the dissertation "Meeting targets: tools to support integrated assessment modelling of global change". [3]
After his graduation Janssen started his academic career as Postdoctoral Research fellow at the Department of Spatial Economics of the Vrije Universiteit Amsterdam. In 2002 he moved to the United States, where he became Associate Research Scientist at the center for the study of Institutions, Population and Environmental Change of the Indiana University, and from 2002 to 2007 Research Scientist. In 2005 he moved to the Arizona State University where he started as assistant professor, and became Associate Professor in 2010, and Professor at the School of Sustainability of the Global Institute of Sustainability in 2015. In 2007 to 2010 he was also Associate Director of its Center for the Study of Institutional Diversity, and since 2010 director of its Center for the Study of Institutional Diversity, since 2015 School of Human Evolution and Social Change. [3]
Janssen research interests are in the field of the "interaction of behavioral, institutional and ecological processes... how people, their institutional rules and the environment they live in fit together in the past, present and the future, from local scales to the global scale," [3] and has developed "formal (computational) models of social and social-ecological systems, and perform controlled experiments in the lab and field, and study case study material to test the stylized models," [3] and particularly on agent-based modeling and institutional analysis.

Human ecology is an interdisciplinary and transdisciplinary study of the relationship between humans and their natural, social, and built environments. The philosophy and study of human ecology has a diffuse history with advancements in ecology, geography, sociology, psychology, anthropology, zoology, epidemiology, public health, and home economics, among others.
Landscape ecology is the science of studying and improving relationships between ecological processes in the environment and particular ecosystems. This is done within a variety of landscape scales, development spatial patterns, and organizational levels of research and policy. Concisely, landscape ecology can be described as the science of "landscape diversity" as the synergetic result of biodiversity and geodiversity.
Evolutionary ecology lies at the intersection of ecology and evolutionary biology. It approaches the study of ecology in a way that explicitly considers the evolutionary histories of species and the interactions between them. Conversely, it can be seen as an approach to the study of evolution that incorporates an understanding of the interactions between the species under consideration. The main subfields of evolutionary ecology are life history evolution, sociobiology, the evolution of interspecific interactions and the evolution of biodiversity and of ecological communities.
Spatial ecology studies the ultimate distributional or spatial unit occupied by a species. In a particular habitat shared by several species, each of the species is usually confined to its own microhabitat or spatial niche because two species in the same general territory cannot usually occupy the same ecological niche for any significant length of time.
In economics, a common-pool resource (CPR) is a type of good consisting of a natural or human-made resource system, whose size or characteristics makes it costly, but not impossible, to exclude potential beneficiaries from obtaining benefits from its use. Unlike pure public goods, common pool resources face problems of congestion or overuse, because they are subtractable. A common-pool resource typically consists of a core resource, which defines the stock variable, while providing a limited quantity of extractable fringe units, which defines the flow variable. While the core resource is to be protected or nurtured in order to allow for its continuous exploitation, the fringe units can be harvested or consumed.
A coupled human–environment system characterizes the dynamical two-way interactions between human systems and natural systems. This coupling expresses the idea that the evolution of humans and environmental systems may no longer be treated as individual isolated systems.
Elinor Claire "Lin" Ostrom was an American political scientist and political economist whose work was associated with New Institutional Economics and the resurgence of political economy. In 2009, she was awarded the Nobel Memorial Prize in Economic Sciences for her "analysis of economic governance, especially the commons", which she shared with Oliver E. Williamson; she was the first woman to win the prize.
In its broadest sense, social vulnerability is one dimension of vulnerability to multiple stressors and shocks, including abuse, social exclusion and natural hazards. Social vulnerability refers to the inability of people, organizations, and societies to withstand adverse impacts from multiple stressors to which they are exposed. These impacts are due in part to characteristics inherent in social interactions, institutions, and systems of cultural values.
The Lancaster Environment Centre (LEC) in Lancaster, England, is an interdisciplinary centre for teaching, research and collaboration at Lancaster University, founded in 2007.
Christopher B. Field is an American scientist and researcher, who has contributed to the field of climate change. The author of more than 200 scientific publications, Field's research emphasizes impacts of climate change, from the molecular to the global scale. His work includes major field experiments on responses of California grassland to multi-factor global change, integrative studies on the global carbon cycle, and assessments of impacts of climate change on agriculture. Field's work with models includes studies on the global distribution of carbon sources and sinks, and studies on environmental consequences of expanding biomass energy.
A social-ecological system consists of 'a bio-geo-physical' unit and its associated social actors and institutions. Social-ecological systems are complex and adaptive and delimited by spatial or functional boundaries surrounding particular ecosystems and their context problems.
Carl Folke, is a trans-disciplinary environmental scientist and a member of the Royal Swedish Academy of Sciences. He is a specialist in economics, resilience, and social-ecological systems, viewing such systems as intertwined and potentially unexpected in their interactions. As a framework for resource management, this perspective brings important insights to environmental management, urban planning, and climate adaptation. He suggests ways to improve our ability to understand complex social-ecological interactions, deal with change, and build resilience, often working at smaller scales as a step towards addressing larger scales.
The Institutional Analysis and Development framework (IAD) is a theoretical framework for investigating how people ("actors") interact with common-pool resources (CPRs). CPRs are economic goods which are rivalrous and non-excludable - examples include forests as a source of timber, or fields as a source of pasture.
