Cowes Harbor Port Authority: Multi-use CPR with Oyster Fishery, Isle of Wight, United Kingdom | Case |
| Cowes Harbor is a part of the Medina Estuary at the mouth of the River Medina where it enters The Solent, a 5km wide channel between the northern most point of the Isle of Wight and the English mainland in the United Kingdom. The case study discusses the institutional arrangements conducted by the Cowes Harbor Commission (CHC) over approximately one hundred years of operation (1897 – 1997). Multiple uses take place in the harbor which are overseen by the CHC, including shipping, transportation... | 09 Aug 2016 |
Deulgaon forest community, Gadchiroli district, Maharashtra, India | Case |
| The Deulgaon forest community is located approximately 18 km from the town of Dhanora in the Gadchiroli district of Maharashtra, India. It encompasses a geographical area of 718.48 ha of which 601.37 ha are community forest. The case study involves an undetermined snapshot in time and catalogues an action situation involving 173 community members organized in 33 households which are dependent on the forest for fuelwood, fodder, timber, and wildlife resources. Timber and forest... | 09 Aug 2016 |
Effect of infrastructure design on commons dilemmas | Model |
| The authors address the question of how infrastructure design affects SES sustainability in two stages. First, they explore the effects of design variations in shared infrastructure on long-term system behavior in a model system. They examine two types of distribution infrastructure, one with and one without upstream−downstream asymmetry, and different threshold characteristics of infrastructure maintenance. Second, they evaluate how these design variations influence the robustness of... | 09 Oct 2016 |
Felderin irrigation system, Torbel, Switzerland | Case |
| This case was part of the original CPR database developed in the 1980s by Edella Schlager and Shui Yan Tang at Indiana University and may be found under the CPR tab under Institutional Analysis.The resource appropriated from Felderin Irrigation is water for irrigation. The Felderin is one of the three irrigation networks in Torbel, a village in the Swiss Alps. The Felderin is regulated without central authority or official mechanisms for adjudication. Upkeep is provided by a half dozen men... | 09 Aug 2016 |
Fermeuse Cod and Salmon Fishery, Newfoundland, Canada | Case |
| Fermeuse is an inshore fishing community that is located on the southern shore of Newfoundland's Avalon Peninsula, the island's eastern-most coastline. The original study, which was carried out in 1972, catalogues an action situation involving approcimately 56 fishermen and 24 fishing units or boats and crew; the resource units are cod and salmon. Allocation of fishing spots depends on the season. The commonly used allocation processes are "first-in-time, first-in-right", lottery, and division... | 09 Aug 2016 |
Fishery Robustness Diagram | Case |
| This case is to illustrate the functionality of the dynamic robustness diagram. Right now, the descriptions are very limited. They will become much more detailed as the research continues. | 09 Aug 2016 |
Fractal Poverty Traps | Model |
| The dynamic model for poverty traps contains parameters as government policies and technologies, and variables such as income, expenditures, assets holdings and anthropometric status. This dynamic model for poverty traps offers a new perspective by showing the existence of multiple stable equilibria, which implies that there's one unstable dynamic equilibria. At this unstable equilibria, any little shock in the system will cause a switch to state equilibrium. Different to the standard economic... | 29 Nov 2017 |
Institutional Analysis of Tourism system from a Commons Perspective in Upper Mustang, Nepal | Case |
| Before the introduction of tourism, people of Upper Mustang subsisted on only three occupations: agriculture, animal husbandry, and petty trans-Himalayan trade. The Upper Mustang region of Nepal has long been a tourist destination, especially for the westerners. Once popularly known as a Lost Kingdom of Nepal, this region is located in the rain-shadowed with harsh climatic conditions, but evokes a mystical and exotic image for tourists because of its unique landscapes and rich cultural heritage... | 05 Dec 2018 |
Irrigation watercourse, "Area Four", Taiwan | Case |
| The resource appropriated from this watercourse in Area Four (actual names of communities removed in case study) is water for irrigation. At the beginning of the study, the authors describe a moderate shortage of biological and physical resources withdrawn compared to the number of units available. Area Four has irrigation associations run by full-time officials, although there used to be farmers' representative committees, but at the time of the study they were temporarily suspended. There are... | 09 Aug 2016 |
Irrigation watercourse, "Area One", Pakistan | Case |
| The resource appropriated from this watercourse in Area One (actual names of communities were removed in the case study) is water for irrigation. Area One is a large irrigation system managed by a government bureaucracy. There are no formal organizations at the watercourse level, though informal arrangements exist in all watercourses for mobilizing farmers to carry out maintenance on a communal basis. The system as a whole is not managed effectively. There are over 5000 total appropriator teams... | 09 Aug 2016 |
Jambudwip Marine Fishery, India | Case |
| Jambudwip, an island in the Bay of Bengal, is located about 7 miles to the southwest of Bakkhali in the South 24 Parganas district in the state of West Bengal, India. The original case, which spans from 1967-1968, catalogues an action situation involving approximately 243 fishermen in the village; the resource unit are demersal and midwater fish species. The boundary is based on traditional use and technology limitations. Two distinct types of institutional arrangements exist among the... | 09 Aug 2016 |
Kampong Mee Trawl Fishery, Malaysia | Case |
| Kampong Mee is a fishing community that is located near the urban areas of Penang and several other fishing ports in Malaysia. The original case, which was published in 1977, catalogues approximately 2,000 inhabitants and 150 boats; the resource unit is demersal fish. Overfishing is the main common pool resource problem. In an attempt to limit overfishing, six co-operatvies were established. Co-operative committee heads are appointed by the government and were established to manage the... | 09 Aug 2016 |
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... | 13 Jul 2017 |
Lorenz Model | Model |
| This simple model was developed by Edward Lorenz in 1963 to study fluid mechanics (based on Navier-Stokes equations). It is the first ever model of a chaotic dynamical system. Chaos arises when a deterministic, nonlinear dynamical system exhibits long-term unpredictability in behavior due to sensitivity to initial conditions.The model is a three-dimentional system of differential equations. Specifically, the model describes the convection motion of a fluid in a small idealized "Rayleigh-... | 09 Aug 2016 |
Mathematics of Marital Conflict | Model |
| This discrete time model represents a coupled system as seen through talk turns in a conversation between a wife and husband where each exerts influence dynamically on the other. Cook et al. (1995) develop this entirely social model based on empirical observations of marital conflict in the Gottman Love Lab, a University of Washington social laboratory studying marital conflict and resolution. The authors developed this model, then confirmed the model through turn-wise application of the... | 30 Nov 2017 |
