World-Earth System Governance

Case
This case is a focal point for 'gobal' models - i.e. modes with no particular spatial resolution.  There are many of these - any economic growth model with some sort of ecological constraint.

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...

Nohwa-do and Bogil-do, Communal Water Resources Management, South Korea

Case
Nohwa-do and Bogil-do are South Korea's southernmost islands, located off the coast of the province of Jeollanam-do. They are connected by a bridge and share a reservoir in Bogil-do. The inhabitants of the two islands have to share water since Nohwa-do lacked a reservoir.The primary causes of the commons dillemma in Nohwa-do and Bogil do are a lack of appropriate and effective public participation and a hierarchical decision-making process between local government and central government...

Nam Tan Irrigation Project

Case
The Muong Phieng Valley is located in the Nam Tam watershed in the Sainyabuli Province of western Laos. The main agricultural product is rice. The area suffered major infrastructural changes in two periods. First, during the Nam Tam Irrigation project administered by USAID and the Lao government in the late 1960s and early 1970s. Second, during the Nam Tam Rehabilitation project in the 1990s, supervised by UNDP, UNCF and the Lao government.This case was part of the original CPR database...
