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...

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...

Kottapalle open-field husbandry and canal irrigation, Kurnool district, Andhra Pradesh, South India

Case
Located in the Nowk valley in Kurnool district in the state of Andhra Pradesh in South India, Kottapalle has an area of 4,600 acres. The village is in the tail-end of a 20-mile irrigation canal. The original research was conducted from 1980 to 1982. The state Irrigation Department is responsible for regulating water allocation between each outlet between each village from the canal. The local council is responsible for distribution of water to fields in the village.  Also,...

Lakes Entrance Scallop Fishery

Case
The Lakes Entrance scallop fishery is located in Bass Strait outside the city of Lakes Entrance in eastern Victoria, Australia and as far south as Tasmania in depths of 10-30 fathoms . The original case, which was published in 1982, catalogs the management of both Lakes Entrance and nearby Port Phillip Bay fisheries following a decline in scallop stocks in the early 1970s. The shared resources relevant to the commons dilemma faced by the community include scallop stocks and their productivity (...

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...

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-...

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....

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...

Messolonghi-Etolico Lagoon Fishery

Case
The Messolonghi-Etolico lagoon is in the northern part of Patraikos Gulf, on the west coast of central Greece. The original case, which was published in 1984, catalogues an action situation with approximately 200 independent fishermen and 170 fishermen in 11 co-ops. The resource units are mullets, sea-bream, eel, and sea-bass. The co-ops feel the independents are free-riders on co-op efforts to trap fish; independents resent the co-ops' privileges, power, and subterfuges to restrict membership...

Modeling Human Ecodynamics and Biocultural Interactions in the Late Pleistocene of Western Eurasia

Model
Exploring the dynamic feedbacks between biological and cultural evolutionary systems is critical to understanding the origins of modern human behavior. The authors present a population dynamics model using ordinary differential equations and agent based modeling to delineate the consequences of differing mobility strategies expressed as reproduction potential at the population level for Late Pleistocene hominins in Western Eurasia (i.e., modern Homo sapiens and Neanderthals). The model...

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...

Nae Pae and Muang Mai Irrigation Systems

Case
Fai Muang Mai is one of three irrigation systems along the Mae Klang River in the Chiang Mai Province, Thailand. Muang Mai is the most upstream of the Mae Klang River irrigation systems and provides irrigation to 800 hectares of riceland and orchards through a weir and canal network. The system is managed and maintained by an irrigation organization known as Mu Muang Mai, composed of farmers within the command area. The original case includes a comparative analysis of two traditional irrigation...

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...

Nayband irrigation system

Case
The Nayband Irrigation system is located in The province of Khorasan in north eastern Iran. The original case was reported in 1971 and 1972, and catalogues an action situation involving approximately 80 agricultural related families. The resource appropriated related to the social dilemma is water for irrigation, which is delivered by canals.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...

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...
