The coupled dynamics of human socio-economic choice and lake water system: the interaction of two sources of nonlinearity | Case |
| Suzuki & Iwasa (2009) study a mathematical model for the coupled dynamics of human socio-economic choice and lake water system. In the model, many players choose one of the two options: a cooperative and costly option with low phosphorus discharge, and an economical option with high phosphorus discharge. The choice is affected by an economic cost, a social concern about water pollution, and a conformist tendency. The pollution level in the lake is determined by total phosphorus discharge by... | 09 Aug 2016 |
Conflict between groups of players in coupled socio-economic and ecological dynamics | Case |
| Conflict among multiple groups is a major source of difficulty in environmental conservation. People are often divided into various groups that have different social factors, sometimes leading to differences in the degree to which they cooperate in environmental conservation. This obstructs the social consensus needed to solve the environmental problems. Here we study the coupled dynamics of human socio-economic choice and lake water pollution, and examine the magnitude of the difference in... | 09 Aug 2016 |
Tourists and traditional divers in a common fishing ground | Case |
| Lee & Iwasa (2011) study socio-ecological models for a fishing ground open to tourists. On Jeju Island, Korea, women traditional divers called “Haenyeo” harvest resources in a common fishing ground. To investigate the impact of introducing tourists on the benefit to the fishing association and the resource level, we examine two models that differ in the way the number of tourists is controlled. In the first model, the fishing association charges an entrance fee to tourists and the level of... | 09 Aug 2016 |
Subtle global bifurcation with dramatic ecological consequences in a simple population model | Case |
| Numerous situations exist in which a consumer uses two different kinds of resources, one fixed, the other renewable, e.g., nesting resources and food resources. With an elementary modification of the basic Lotka–Volterra consumer resource equations, we investigate the population dynamics of a consumer dependent on two resources, one fixed, the other renewable. Emerging from this structure is a situation of alternative attractors that remain qualitatively robust over a significant range of... | 09 Aug 2016 |
The inevitability of surprise in agroecosystems | Case |
| Many critical transformations of ecosystems contain advanced signals of their imminence, but it is also true that many critical transformations can be shown to contain no such signal, at least with the sorts of data normally available to field workers. This paper explores some generalized theoretical structures and distinguishes between those that may provide a signal that could be used to predict a critical transformation and those that, by their very nature, do not provide such a clue. I... | 09 Aug 2016 |
Port Lameron Lobster Fishery II, Nova Scotia, Canada | Case |
| Since this original case, much of the Atlantic Canadian fisheries have been reduced to a fraction of historical levels. In Port Lameron, very few harvesters fish for groundfish (cod, haddock, pollock, hake), swordfish, or tuna. The collapse of the Codfishery has been attributed to many issues, including scientific uncertainty, government policies to increase employment in the area, and subsidies to increase fishing capacity, and the inability of enforcement to stop foreign trawlers from... | 09 Aug 2016 |
Kurnool-Cuddapah canal large-scale irrigation system in Andhra Pradesh, South India | Case |
| The Kurnool-Cuddapah (KC) Canal Irrigation System draws water from Tungabhadra river through the Sunkesula Dam on flows through Cuddapah and Kurnool districts in state of Andhra Pradesh in South India providing water to around 120,000 hectares and servicing around 250,000 farm households (check). It was originally built by the Dutch for navigation purposes and later sold to the British and used for irrigation purposes. It was modernized somewhat around 1950s. The main canal is largely a "... | 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 |
Efficacy of consultation procedure as conflict management tool in northern Sweden | Case |
| This forest resource is located in northern Sweden and is used by two different user groups. The case study involves a snapshot in time and catalogues an action situation involving the native Sámi and their reindeer herding communities, and private logging compaines. The Swedish parliament mandated that consultation meetings be held between a logging company and the effected Sámi group before forest logging commence, in an attempt to mitigate conflict. The institutional analysis document... | 09 Aug 2016 |
Common property regime within Lagunas de Montebello National Park, Chiapas, Mexico | Case |
| This research was conducted in Lagunas de Montebello National Park (PNLM) in Chiapas, the sourthernmost state in Mexico. PNLM is a small (6,022 ha) protected area situated in south-central Chiapas, along the border with Guatemala in the ecological transition zone between the central highlands and the lowland tropical rainforests of this state. These forests experienced extensive and severe fires in 1998, due to drought conditions following the El Nino event of 1997. This study documented forest... | 09 Aug 2016 |
San Martin Ocotlán community forest management, Oaxaca, Mexico | Case |
| The San Martin Ocotlán forest community encompasses a total of six settlements located in the state of Oaxaca, Mexico, of which San Martin Ocotlán is the largest. The community has de jure rights to 13,000 ha of common property pine and oak forests. The case study involves a time period from approximately 1958 to the mid to late 1990s and catalogues an action situation involving approximately 3,300 residents organized in circa 600 households, who supplement their subsistence maize farming... | 09 Aug 2016 |

It encompasses a geographical area of 924.43 ha of which 641.71 ha are community forest. The case study involves an undetermined snapshot in time and catalogues an action situation involving 393 community members organized in 81 households which are dependent on the forest for fuelwood, fodder, timber, water, and wildlife, among others. Timber... | 09 Aug 2016 |
Common property regime of the Huaorani Indians, Ecuador | Case |
| Historically the Huaorani Indian society encompassed an area of 20,000 km2 in the Ecuadorian Amazonian region bordered on the north by the Napo River and the south by the Curaray River. The case study involves a historical time period predating first contact with outsiders in 1958 and catalogues an action situation involving an unknown number of individuals organized in small groupings of one to two extended families with a seminomadic movement pattern of cyclical relocation to certain areas... | 09 Aug 2016 |
Common property regime of the Huaorani Indians (modern), Ecuador | Case |
| Contemporary Huaorani Indian society is scattered into approximately two dozen villages located in an area that encompasses the Napo, Orellana, and Pastaza provinces in the Ecuadorian Amazon region. The case study involves a time period from approximately 1996 to the late 1990s and catalogues an action situation involving approximately 1,500 to 2,000 individuals and an unknown number of households who depend on domestic crops, gathered wild fruits, nuts and tubers, as well as hunted game and... | 09 Aug 2016 |
