### Tanowong Bwasao Irrigation

Case
The case study of Tanowong bwasao irrigation is located in the mountain province of Philippines. The resource appropriated is water for irrigation from Tanowong Traditional Irrigation system. Prior to 1954, the Tanowong people relied on water from two streams to irrigate their rice fields. As the water supply became inadequate to meet their cultivation needs, they decided to dig a 25 kilometer ditch to divert water from a new source, the Bwasao Stream, to their fields. Since the project was...

### Gageoda (Kagodo) Island myok grounds, South Korea

Case
This case was part of the original CPR database developed in the 1980s by Edella Schlager and Shui Yan Tang at Indiana University. Seaweed is the resource appropriated from the Kagodo myok grounds. It is harvested from the area surrounding the isolated island of Kagodo, off the southwest coast of Korea. The people collectively own the seaweed grounds and one member from each household can access the grounds. The author discusses three fishing villages and the differences among them in the...

### Mathematical Models in Social Ecological Systems

Case
This case is an umbrella to capture a range of models of ecological, social, social-ecological, and other natural systems (e.g. climate).  In addition, there are several models whose main purpose is to demonstrate model visualization features related to a number of famous mathematical models including the Lorenz Model, the discrete logistic, and predator prey models. The Lorenz Model, probably the most famous of all simple models, is the first ever model of a chaotic dynamical system....

### The Goulburn Broken Catchment irrigation system, northern Victoria, Australia

Case
The GB catchment covers 2.1 million hectares in the Murray-Darling Basin in Australia. Aboriginal people lived in the catchment for millennia before colonization around 1830.  The upper, mountainous area of the catchment (900 000 ha) is more than 50% forested. The mid catchment (1 million ha) of riverine plains, low slopes and foothills has less than 20% of native vegetation cover remaining, which is highly fragmented, and the rest is used for dryland cropping and grazing. The Shepparton...

### Coastal vulnerability to climate change: A comparative study of cases in the UK, France, and South Africa

Case
This case represents the collaborative effort of an international team focused on studying how coastal regions may respond to climate change as part of the Multi-Scale Adaptations to Climate Change and Social-Ecological Sustainability in Coastal Areas (MAGIC) research project funded by a Belmont grant.  The study involved three sites: Cornwall, England; Languedoc-Roussillon, France; and Eden District, South Africa.  The three study sites were selected based on their history of rapidly...

### 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...

### 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...

### 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.

### 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...
