### 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...

### The Kaset Samakee Water User Association, Isan region, northeastern Thailand

Case
The Kaset Samkee water user association is a part of the The Lam Pra Plerng Irrigation Project, constructed by Thailand's Royal Irrigation Department (RID). RID organized four Water User Associations (WUAs) in the project area that are then divided into "chaeks" (a chaek is an area served by a common farm-turn-out). The common irrigator is paid by the RID and is responsible for arranging water distribution and maintenance schedules in the chaek. Farmers in the area of the Kaset Samkee...

### 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...

### 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...

### The Amphoe Choke Chai Water User Association, Isan region, northeastern Thailand

Case
The resource appropriated from A Chaek in Amphoe Choke Chai is water for irrigation. The Lam Pra Plerng Irrigation Project was constructed by Thailand's Royal Irrigation Department, which organized four water user associations (WUAs) in the project area. Each WUA is divided into “chaeks” (a chaek is an area served by a common farm turn-out). One or two common irrigators serve each chaek. The common irrigator is paid by the RID and is responsible for arranging water distribution and maintenance...

### 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...

### System representation template

Case
The system representation template was created to provide the key verbs analysts should utilize when describing the strategic interactions between the elements in the robustness framework (RS, RU, PIP, PI). Verbs followed by (?) are suggested additions to the verb list.

### 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...

### 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...

### 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.

### Nam Tan Irrigation Project

Case
The Nam Tam watershed is located in the Sainyabuli Province of western Laos. The Nam Tan Irrigation Project dammed the river in the late 1960's and downstream rice agriculture in a 2000 hectare area of the Muong Phieng Valley shifted from an indigenous to bureaucratic irrigation system. Initial success of the Project was attributed to the adaptation of the "water headman," a traditional irrigation leadership role, in the formal structure of the Project.This case was part of the original CPR...

### Munglori "Turf" (forest territory) Management, India

Case
Munglori is a village in Uttaranchal, India. The resource appropriated from Munglori Turf Management is fodder. There is a system of informal, locally recognized rules which are respected in and across villages and through which the local oak forests are managed. These rules supersede national laws and result in a reasonable level of forest management. Both institutional and geographical factors affect the boundary of the resource. From the standpoint of social-ecological systems analysis...

### 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...

### 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....
