An Update on the Scholarly Networks on Resilience, Vulnerability, and Adaptation within the Human Dimensions of Global Environmental Change Ecology and Society
Janssen, Marco A; Arizona State University; Marco.Janssen@asu.edu.
In Janssen et al. (2006), we presented a bibliometric analysis of the resilience, vulnerability, and adaptation knowledge domains within the research activities on human dimensions of global environmental change. We have updated the analysis because 2 years have gone by since the original analysis, and 1113 more publications can now be added to the database. We analyzed how the resulting 3399 publications between 1967 and 2007 are related in terms of co-authorship and citations. The rapid increase in the number of publications in the three knowledge domains continued over the last 2 years, and we still see an overlap between the knowledge domains. We were also able to identify the “hot” publications of the last 2 years.

Empirically Based, Agent-based models Ecology and Society
Janssen, Marco A; Arizona State University; Marco.Janssen@asu.edu; Ostrom, Elinor; Indiana University and Arizona State University; ostrom@indiana.edu.
There is an increasing drive to combine agent-based models with empirical methods. An overview is provided of the various empirical methods that are used for different kinds of questions. Four categories of empirical approaches are identified in which agent-based models have been empirically tested: case studies, stylized facts, role-playing games, and laboratory experiments. We discuss how these different types of empirical studies can be combined. The various ways empirical techniques are used illustrate the main challenges of contemporary social sciences: (1) how to develop models that are generalizable and still applicable in specific cases, and (2) how to scale up the processes of interactions of a few agents to interactions among many agents.

Games for groundwater governance: field experiments in Andhra Pradesh, India Ecology and Society
Meinzen-Dick, Ruth; International Food Policy Research Institute; R.Meinzen-Dick@cgiar.org; Chaturvedi, Rahul; Foundation for Ecological Security; rahul.chaturvedi@fes.org.in; Ghate, Rucha; International Center for Integrated Mountain Development; ruchaghate@gmail.com; Janssen, Marco A; Arizona State University; Marco.Janssen@asu.edu; Rollins, Nathan D; Arizona State University; nathan.rollins@asu.edu; Sandeep, K; Foundation for Ecological Security; sandeep@fes.org.in.
Groundwater is a common-pool resource that is subject to depletion in many places around the world as a result of increased use of irrigation and water-demanding cash crops. Where state capacity to control groundwater use is limited, collective action is important to increase recharge and restrict highly water-consumptive crops. We present results of field experiments in hard rock areas of Andhra Pradesh, India, to examine factors affecting groundwater use. Two nongovernmental organizations (NGOs) ran the games in communities where they were working to improve watershed and water management. Results indicate that, when the links between crop choice and groundwater depletion is made explicit, farmers can act cooperatively to address this problem. Longer NGO...

Learning, Signaling, and Social Preferences in Public-Good Games Ecology and Society
Janssen, Marco A; Arizona State University; Marco.Janssen@asu.edu; Ahn, T. K.; Florida State University and Korea University; tahn@fsu.edu.
This study compares the empirical performance of a variety of learning models and theories of social preferences in the context of experimental games involving the provision of public goods. Parameters are estimated via maximum likelihood estimation. We also performed estimations to identify different types of agents and distributions of parameters. The estimated models suggest that the players of such games take into account the learning of others and are belief learners. Despite these interesting findings, we conclude that a powerful method of model selection of agent-based models on dynamic social dilemma experiments is still lacking.

Toward a Network Perspective of the Study of Resilience in Social-Ecological Systems Ecology and Society
Janssen, Marco A; Arizona State University; Marco.Janssen@asu.edu; Anderies, John M; Arizona State University; m.anderies@asu.edu; Elmqvist, Thomas; Stockholm University; thomase@ecology.su.se; Ernstson, Henrik; Stockholm University; henrik@ecology.su.se; McAllister, Ryan R.

Formal models used to study the resilience of social-ecological systems have not explicitly included important structural characteristics of this type of system. In this paper, we propose a network perspective for social-ecological systems that enables us to better focus on the structure of interactions between identifiable components of the system. This network perspective might be useful for developing formal models and comparing case studies of social-ecological systems. Based on an analysis of the case studies in this special issue, we identify three types of social-ecological networks: (1) ecosystems that are connected by people through flows of information or materials, (2) ecosystem networks that are disconnected and fragmented by the actions of...
