A Tailend Watercourse in "Area Two", India

Case
The resource appropriated from A Tailend Watercourse in Area Two is water for irrigation to farmlands. The resource discussed in this study is a watercourse located in the tail-end part of a large irrigation system. Area Two is a large irrigation system managed by a government agency. There are neither users' organizations nor effective rules governing water rotation at the watercourse level. Great inequalities exist between head-end and tail-end farmers.This case study is part of the original...

A Two-Sector Growth Model: Economic Development, Demographics, and Renewable Resources

Model
This is a two-sector growth model that couples the dynamics of human demographics and a renewable resource base. The two sectors are agricultural and manufacturing sectors. To capture both the positive (Malthusian) and negative (modern growth) type relationships between population growth and output, it is important to model the shifting composition of output from agricultural to manufacturing as growth occurs. Thus, the model is a two sector (productions and consumptions in...

Alanya Coastal Fishery, Turkey

Case
The coastal fishery in Alanya is situated in Antalya Province along the southern Mediterranean coast of Turkey. The original case, which spans from 1976-1978, catalogues approximately 100 registered farmers operating 45 small inboard boats; pelagic fish (including bonits and large carangids) are the target resource unit. There is only one user group organization and no subgroups (just one group of small boat fishermen). The fishermen cooperate with one another and have access rules that involve...

Animated demonstration of the Lorenz Model

Model
Animated demonstration of the Lorenz model and its sensitivity to initial conditions.  The simulation starts with twenty points very close to each other, and follows them as they move further away. The starting values differ in the fifth and sixth significant digits of a single coordinate. The Lorenz model was developed by Edward Lorenz in 1963 to study fluid mechanics.The model is a three-dimentional system of differential equations. Specifically, the model describes the convection motion of a...

Archetype Analysis in Commons Research

Case
This is a collaborative project based on the  IASC Arizona 2020 workshop panel on archetype analysis for commons research. Archetypes are increasingly used across a wide range of sustainability themes for “pattern recognition, diagnosis, or scenario development”.  The work draws on a family of cases from the Social-Ecological Systems (SES) Library at ASU - to explore how archetype analysis can be used to synthesize results from a set of case studies.  A second goal is...

Artisanal green turtle fishery in eastern (Caribbean) Nicaragua

Case
The artisanal green turtle fishery is operated by the indigenous Miskito along Nicaragua's eastern (Caribbean) coast between the city of Bluefields in the south and Puerto Cabezas in the north.  The original case study focused on the village of Tasbapauni which is located approximately 40 miles north of the capital Bluefields on a narrow beach separating Pearl Lagoon from the ocean.  The initial report covers a time period from approximately 1968 to 1969, as well as part of 1971, and...

Ascension Bay Lobster Fishery

Case
Ascension Bay is located in Quintana Roo State, Mexico. The resource appropriated from the Ascension Bay Lobster Fishery is lobster. In this case, the fisheries are organized by co-ops or firms. Institutional arrangements are such that members of the Ascension Bay Lobster Fishery co-op can trade or sell lobster territories since members own the territories that they fish from. This case was part of the original CPR database developed in the 1980s by Edella Schlager and Shui Yan Tang at...

Baccalaos Cove Cod Fishery, Canada

Case
The fishing community, Baccalaos Cove, is located in the Placentia Bay on the eastern shore of the Burin Peninsula of Newfoundland, in the eastern part of Canada on the Atlantic coast. The original case, which spans from 1977-1979, catalogues an action situation of approximately 300 fishermen; the resource unit is cod. Depending on the season, different allocation techniques are used for assigning fishing spots; lottery system in summers and "first-in-time, first-in-right" process in the fall....

Baghmara Ko Kulo, Sikharpur Village Panchayat, Sindhupachok District, Nepal

Case
This case is part of the original Nepal Irrigation Institutions and Systems (NIIS) database developed in the 1980's by a team of researchers under the direction of Dr. Elinor Ostrom at Indiana University. In addition, this case is also part of a longitudinal study that has repeatedly investigated 19 farmer-managed irrigation systems (FMIS) in the Indrawati River Basin that participated in an innovative intervention designed to improve irrigation performance not only by improving physical...

The rice paddies and irrigation system of this case are near Tihingan village, in the Klungkung district of Bali, Indonesia ‐ 45 km northeast of Denpasar. The original case spans from 1957 to 1959, and it catalogues an action situation involving 455 rice farmers who are members of an organization that regulates irrigation and planting cycles (a subak). The subak system in Bali represents a longstanding tradition for irrigation, dating back to at least the 12th century (some estimates suggest as...

Brander-Taylor Model

Model
This is the original Brander-Taylor Easter Island model. Brander and Taylor (1998) describes the model as the following: "The paper presents a general equilibrium model of renewable resource and population dynamics related to the Lotka-Volterra predator-prey model, with man as the predator and the resource base as the prey. We apply the model to the rise and fall of Easter Island, showing that plausible parameter values generate a 'feast  and famine" pattern of cyclical adjustment in...

Cadchog irrigation system, Bontoc municipality, Philippines

Case
Cadchog Irrigation takes place in the Bontoc municipality, Mountain Province, Philippines. The resource appropriated is water for irrigation. At the beginning of the period, there was an apparently balanced supply of biological and physical resources withdrawn compared to the number of units available. The irrigation system can generally provide enough water to the appropriators. There is no formal organization to manage this system, although two women have been appointed as leaders. There are...
