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....

Ballynakill Harbour multi-use co-operative, Connemara District, Ireland

Case
Ballynakill Harbour is located on the northwest part of Connemara, a region on the west coast of Ireland. Use of the harbor has moved from predominantly single-use, involving commercial and domestic fishing, to multiple uses including: fishing for shrimp, white fish, and salmon; as well as finfish and shellfish aquaculture, oyster farming, and marine tourism. The case study focuses on the activities of the North Connemara Marine Co-operative which was formed through collective action between...

Caye Caulker Lobsterfishing

Case
Caye Caulker is a small coral island located 15 miles o the northeastern coast of Belize. Boundaries are drawn based on natural barriers such as the barrier reef, that lies to the east of the Caribbean Sea. The set of individuals who have rights to withdraw from this resource were well-de ned at the time of the study. When the case was documented, the appropriators were attempting to exercise de facto closed access to the lobster fishery. The resource appropriated...

Chawk 16000L Dhabi Minor irrigation system

Case
The Irrigation System is located in the village Dhabi Kalan, Haryana, India at 100 miles northwest of India. The resource appropriated related to the social dilemma is water for irrigation that flows through a canal to a command area. The original cases were reported in 1980 by two authors. One author (Vander Velde 1980) argues that the irrigation system has benefited the dominant caste, Jat, more than other poorer castes in Dhabi Kalan. Another researcher, Reidinger (1980), suggests that...

Communal irrigation management, Lari, Colca Valley, Peru

Case
This study focuses on water use in irrigation.  The case is characterized by well-defined boundaries: Once water enters an irrigation cluster it comes under the control of the landowners. There is evidence of congruence between appropriation and provision rules and local conditions as water is distributed according to time sequence (p. 57), spatial sequence (p. 58), and crop irrigation sequence (p. 59, 105). The sequence can be adjusted within a irrigation cluster since microclimates,...
