Archetype Analysis in Commons Research

Case
This is a collaborative project based on the  IASC Arizona 2020 workshop panel on archetype analysis for commons research. Archetypes are increasingly used across a wide range of sustainability themes for “pattern recognition, diagnosis, or scenario development”.  The work draws on a family of cases from the Social-Ecological Systems (SES) Library at ASU - to explore how archetype analysis can be used to synthesize results from a set of case studies.  A second goal is...

OpenABM: Agent-based model database

Case
OpenABM is a node in the CoMSES Network, providing a growing collection of tutorials and FAQs on agent-based modeling, a model library intended to provide a locus for authors and modelers to share their models, and forums for modeling-related discussions and job postings.You can find OpenABM here: www.openabm.org.

Large N Comparative Studies of Ostrom's Design Principles

Case
There have been a number of studies that focus on testing whether and in what contexts Ostrom's institutional design principles may lead to successful governance of common-pool resources.  The study of Cox et al. (see sources) coded the presence or absence of each of 8 design principles and success in 62 cases and found that the likelihood of success and the presence of individual design principles is positively correlated.   However, because institutions are systems, it is...

Waterwheel Model

Model
This model describes the dynamics of a waterwheel. The wheel has 10 cups that are filled when as they pass over the top of the arc of the wheel (imagine a Ferris wheel where instead of seats there are buckets. Water is flowing down on the Ferris wheel filling the buckets). The weight of the water makes the wheel turn. However, in this model, the buckets leak. So if the flow of the water from the top is too slow, some interesting motion can occur. This waterwheel model is a perfect physical...

Brander-Taylor Model

Model
This is the original Brander-Taylor Easter Island model. Brander and Taylor (1998) describes the model as the following: "The paper presents a general equilibrium model of renewable resource and population dynamics related to the Lotka-Volterra predator-prey model, with man as the predator and the resource base as the prey. We apply the model to the rise and fall of Easter Island, showing that plausible parameter values generate a 'feast  and famine" pattern of cyclical adjustment in...

Pezzey-Anderies Model

Model
This model describes the Pezzey-Anderies extension to the Brander-Taylor Easter Island model. In addition to the parameters in the Brandor-Taylor model, Pezzey and Anderies have introduced $tax$ and $h_m$. Pezzey and Anderies (2003) gives the following overview: "We extend the Brander–Taylor model of population and resource development in an isolated society by adding a resource subsistence requirement to people's preferences. This improves plausibility; amplifies population overshoot and...

The Discrete Logistic

Model
The logistic is the simplest representation of population dynamics  that contains a minimum level of biological realism.  If we imagine a  population of individuals at time t, the number of individuals in the next period (periods can range from seconds to days to decades depending on the organism) is the number of individuals now plus the number of births minus the number of deaths.  If we assume in the simplest case there are no environmental constraints on births or deaths...

San Pedro Fishery, Belize

Case
     San Pedro, Belize is an island village of approximately 1,200 residents in 1979. Located off the coast of Belize in a strategic place on Ambergris Cay it is close to abundant local fishing and has easy access to nearby commercial markets (Belize city, Corozal, and Chetumal). The fishing cooperative, Caribena Cooperative Limited, was San Pedro’s official fishing organization handling capture, processing and sale of the village’s primary resource: marine produce consisting of...

Mount Desert Island Lobster Fishery

Case
The lobster grounds of Mount Desert Island are located within Hancock County, Maine, some 250 miles northeast of Boston and 150 miles southwest of the U.S. - Canada border. The original case spans from 1969 to1974 and catalogues an action situation involving approximately 75 lobster fishermen; lobster is the stationary resource unit.This case study is part of the original Common-Pool Resource (CPR) database. A summary of the original CPR coding conducted in the 1980s by Edella Schlager and Shui...

Ayvalik-Haylazli Lagoon Fishery

Case
The Ayvalik-Haylazli lagoon fishery is located on the Turkish Mediterranean coast near the town of Adana. The resource units are demersal fish (mullets, groupers, and snappers). The original case, which spans from 1976-1978, catalogues an action situation involving 103 registered fishermen from three neighboring villages. As of 2011, the fishery and its adjacent waters are harvested by 397 registered fishermen from three neighboring villages. There are user group organizations (...

Alanya Coastal Fishery, Turkey

Case
The coastal fishery in Alanya is situated in Antalya Province along the southern Mediterranean coast of Turkey. The original case, which spans from 1976-1978, catalogues approximately 100 registered farmers operating 45 small inboard boats; pelagic fish (including bonits and large carangids) are the target resource unit. There is only one user group organization and no subgroups (just one group of small boat fishermen). The fishermen cooperate with one another and have access rules that involve...
