"A" irrigation watercourse, "Area Three", Indonesia | Case |
| The resource appropriated from A Watercourse in Area Three is water for irrigation. Area Three is a large irrigation system run by a government agency. At the watercourse level, there are strong village organizations responsible for distributing water and maintaining ditches. These organizations, however, have no role in decisions concerning system-wide management. The boundaries of the location are the boundaries of the watercourse. This is one of four cases studies used in a comparative case... | 09 Aug 2016 |
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... | 09 Aug 2016 |
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... | 09 Aug 2016 |
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... | 09 Aug 2016 |
Ayvalik-Haylazli Lagoon Fishery, Turkey | Case |
| The Ayvalik-Haylazli lagoon fishery is located on the Turkish Mediterranean coast near the town of Adana. The resource units are demersal fish (mullets, groupers, and snappers). The original case, which spans from 1976-1978, catalogues an action situation involving 103 registered fishermen from three neighboring villages. There is only one user group organization (referred to as a co-op) and all active fishermen are members in it. The charter of the co-op defines rules for membership. The co-op... | 09 Aug 2016 |
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.... | 09 Aug 2016 |
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... | 09 Aug 2016 |
Caye Caulker Lobsterfishing | Case |
| Caye Caulker is a small coral island located some 15 miles off the northeastern coast of Belize. The resource unit being appropriated is lobster. 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-defined 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.... | 09 Aug 2016 |
Coastal vulnerability to climate change in Cornwall, United Kingdom | Case |
| Cornwall is located in southwest England on the Cornish peninsula. It stretches between the cities of Bude and Plymouth in the north and Penzance and Falmouth in the south. The study area encompasses numerous communities of various sizes in the coastal and inland areas, including within the Tamar catchment along the rivers Camel, Fowey, Looe, as well as coastal lagoons and basins, and a mix of freshwater and brackish wetlands. The Cornwall study site is catalogued by an action arena in which: (... | 09 Aug 2016 |
Coastal vulnerability to climate change in the Languedoc coastal region, southern France | Case |
| The Languedoc coastal zone is located in the delta region of the river Rhone bordering the Mediterranean Sea between Montpellier and the Petite Camargue in southern France. The study site also encompasses 20 km (~12.43 miles) of the inland area, including numerous communities of various sizes, the Lez and Vistre rivers, coastal lagoons and basins, and a mix of freshwater and brackish wetlands. The Languedoc study area is characterized by an action arena in which (1) rapid population... | 09 Aug 2016 |
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,... | 09 Aug 2016 |
Community coral reef fishery, Ahus village, Ahus Island, Papua New Guinea | Case |
| The Ahus village coral reef is located off of the west coast of Manus Island north of Karkar Island and the mainland of Papua New Guinea. Approximately 600 residents live on a small (28 ha), densely populated, low-lying island with few terrestrial resources. A reported 77% of the population depends upon fishing as their primary occupation. The original case authors focus on the socioeconomic factors and context which influence the success of marine protected areas in Papua New Guinea.The case... | 09 Aug 2016 |
Community coral reef fishery, Muluk village, Karkar Island, Papua New Guinea | Case |
| The Muluk community coral reef fishery is located on the eastern side of Karkar Island off the northern shores of the Madang Province in Papua New Guinea. Karkar Island is a volcanic island with substantial terrestrial resources. The Muluk community consists of 330 people in 50 households, with just 5% depending on fishing as their primary occupation.

Community forest, Dhulikhelko Thulo Ban, Kabhrepalanchok district, Nepal (I) | Case |
| This article examines the role played by local institutions in determining the conditions of two forests located in the Middle Hills of Nepal. Of the two forest systems (the forest, its users, and forest governance system combined) located within the Kabhrepalanchok district, one is Dhulikhelko Thulo Ban (hereafter, Dhulikhel). The findings show that the two forests are different in level of historical degradation as well as present conditions, and these differences are... | 09 Aug 2016 |

| This article examines the role played by local institutions in determining the conditions of two forests located in the Middle Hills of Nepal. Of the two forest systems (the forest, its users, and forest governance system combined) located within the Kabhrepalanchok district, one is Jyalachitti. The findings show that the two forests are different in level of historical degradation as well as present conditions, and these differences are generally explained by the structural... | 09 Aug 2016 |
