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 Evolution of Social Norms in Common Property Resource Use

Case
The problem of extracting commonly owned renewable resources is examined within an evolutionary-game-theoretic framework. It is shown that cooperative behavior guided by norms of restraint and punishment may be stable in a well-defined sense against invasion by narrowly self-interested behavior. The resource-stock dynamics are integrated with the evolutionary-game dynamics. Effects of changes in prices, technology, and social cohesion on extraction behavior and the long-run stock are analyzed....

The coupled dynamics of human socio-economic choice and lake water system: the interaction of two sources of nonlinearity

Case
Suzuki & Iwasa (2009) study a mathematical model for the coupled dynamics of human socio-economic choice and lake water system. In the model, many players choose one of the two options: a cooperative and costly option with low phosphorus discharge, and an economical option with high phosphorus discharge. The choice is affected by an economic cost, a social concern about water pollution, and a conformist tendency. The pollution level in the lake is determined by total phosphorus discharge by...

The application of commons theory on marine resource management

Case
This case was part of a study to determine whether the institutional design principles of Ostrom were, in fact, related to "governance success" by Cox et al.  In that analysis, this case was not included in the end.

The Alaskan Pollock Fishery, Bering Sea, USA

Case
The Alaskan Pollock fishery has been described as a management success, largery attributed to the adoption of ITQs, with allocations to catchers, processers, and to Alaskan communities.  The processor-fisher relationship seems key to the current success at reducing effort in the fishery. Quota is split among catcher-vessels (45%), catcher processer vessels (36%), motherships (9%), and community development quota groups (10%). There is a much smaller number of boats fishing than before...

Ten - Dakh Branch watercourse irrigation, Punjab province, Pakistan

Case
This case was part of the original CPR database developed in the 1980s by Edella Schlager and Shui Yan Tang at Indiana University. The resource appropriated from Watercourse Ten-Dakh Branch is water for irrigation. Based on an intensive survey of ten improved watercourses in Punjab, this study shows the inadequacy of present forms of social organization of watercourses for insuring their adequate maintenance. The study suggests the following sociological characteristics as conducive to good...

Teleconnected vulnerabilities of Mexican and Vietnamese coffee systems

Case
The case study of smallholder coffee producers’ vulnerability in Mexico and Vietnam was published in the journal Environmental Science and Policy in 2008. The authors Hallie Eakin, Alexanda Winkels and Jan Sendzimir explore cross-scale linkages and teleconnectons in the Mexican and Vietnamese coffee systems. This case study is an addition to the SES library and was entered in 2013 by Ashwina Mahanti at Arizona State University. The original case study illustrates that vulnerability in a...

Tasucu Bay Coastal Fishery, Turkey

Case
The coastal fishery in Tasucu Bay is located near the small port town of Tasucu in Mersin Province, Turkey. The original case, which spans from 1976-1978, catalogues 140 fishermen and 90 small inboard boats; the resource unit is demersal fish. It is a relatively simple CPR because there is only one user group of small boat fishermen. All of the fishermen belong to the local cooperative. The cooperative has successfully controlled access to the CPR by fighting off competing users. It provides...

Tarahumara Gentiles agriculture, Sierra Madres, northwest Mexico

Case
The resource under consideration here is arable land. Arable land is a common pool resource in this case. On the dimensions of subtractability and excludability defined by Ostrom (2005), land is highly subtractble, but it is difficult to exclude resource users from land that is not continuously cultivated. In essence, cultivating a parcel of land means that there is less available land in the system; however, it is very difficult to exclude people from obtaining sufficient land for their...

Taos valley acequias community-based irrigation system, Taos, New Mexico, USA

Case
Key findings: The Taos valley acequias have survived for several hundred years as a community-based irrigation system due to a mix of social and biophysical features. These include: A low-cost decentralized monitoring system that is enabled by both water distribution institutions and the geographic location of users Multiple levels of governance built up by key actors within each acequia A system of shallow groundwater aquifers which are particularly important during droughts, and which are...

Tanowong traditional irrigation system, Philippines

Case
The case study of Tanowong traditional 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...

Tanowong Bwasao Irrigation II, Philippines

Case
This paper is an update on a prior case study about the Bwasao irrigation system (Case Nos. 38 and 39) analyzing Albert S. Bacdayan’s 1980 case study on the Tanowong people of three distinct villages in the northern Philippines. For purposes of this report, the SES study boundaries were expanded to include the entire Cordillera region in the northern Philippines.  Case Summary:  Since the Tanowong people built the Bwasao irrigation canal in 1954 to accommodate the villages’ growing...

Takkapala communal irrigation system, Malino village, south Sulawesi, Indonesia

Case
The Takkapala communal irrigation system was studied in the Malino village in Indonesia. The resource harvested is water for irrigation. Although an extensive description of the institutions in the Takkapala Communal System was not presented in this case study on irrigation, the authors did highlight the impact of national subsidies on the rehabilitation of two small-scale river-diversion irrigation systems in Indonesia. Subsidies were substantial inducements to the mobilization of local...

T Water User Association self-governance, Fujian province, southern China

Case
T water user association, also a farmer organization at village level, is located in Fujian province. It has been operating effectively since its creation in 2001 so this is a successful case of self-management. The main reasons are attributed to 3 aspects: the village’s own water resource of reservoir and river, the inter-nested structure of association, village committee and clan, and the low cost punishment environment of village norms. These promote the farmers to self organize and craft...

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.
