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... | 29 Nov 2017 |
OpenABM: Agent-based model database | Case |
| OpenABM is a node in the CoMSES Network, providing a growing collection of tutorials and FAQs on agent-based modeling, a model library intended to provide a locus for authors and modelers to share their models, and forums for modeling-related discussions and job postings.You can find OpenABM here: www.openabm.org. | 14 Jul 2017 |
Oyster communities, Gulf of Mexico, Alabama, USA | Case |
| The Alabama oyster fishing communities are located on the Gulf of Mexico with approximately 100 kilometers of coastline. The case study states that this is an open-access fishery but includes a limited amount of historic data on the development of community based norms and institutions for managing the fishery over time and compares them to those used in the Louisiana oyster fishing community (see related cases below). No information is provided on the number of users involved in the fishery at... | 09 Aug 2016 |
Oyster communities, Gulf of Mexico, Louisiana, USA | Case |
| The Louisiana oyster fishing communities are located on the Gulf of Mexico with approximately 400 kilometers of coastline in a straight line from the border of Texas on the west to the border of Mississippi on the east. The case study involves historic information on the development of community based norms and institutions and a legally closed tenure structured around oyster leaseholds in Louisiana, compared to other open-access community-based oyster fisheries on the U.S. Gulf Coast. The case... | 09 Aug 2016 |
Parwara Van Panchayat Forest | Case |
| Parwara is located in the Nainital district of Uttarakhand, India and forests comprise broad-leaved species such as oak. Resources appropriated from the Parwara forests are timber, grass, and leaves. The authors Vishwa Ballabh and Katar Singh, first visited Parwara in 1988 to evaluate the factors that enabled collective action by the panchayat. Based on the initial assessment from a Social-Ecological Sytems (SES) perspective in 1988, the Panchayat was considered successful in managing... | 09 Aug 2016 |
Parwara Van Panchayat Forest: Social structure and exogenous drivers | Case |
| This paper is an extension of two prior case studies about the Parwara Van Panchayat (forest council):the 1988 Parwara Van Panchayat Forest which covered the status of this social-ecological system (SES) from approx. 1931 to 1985 (Case No. 34); andthe 2008 Parwara Van Panchayat Forest II which provided a SES update up to 2007 (Case No. 159).For purposes of this report, the SES study boundaries were extended beyond the Parwara village Van Panchayat to include an institutional analysis of various... | 09 Aug 2016 |
Parwara village Van Panchayat: Institutional change | Case |
| The main appropriated resources are grass, used mainly for cattle grazing and compost, and forest tress, used mostly for fuel wood and construction timber. Almost all of the total resource units appropriated in the Parwara Van Panchayat (VP) forest are officially regulated by the Parwara Van Panchayat Committee (VPC), timber and resin are regulated by the state Forest Department. The Nainital District Magistrate, and the Van Panchayat Inspector, who is employed by the state Revenue Department,... | 09 Aug 2016 |
Pezzey-Anderies Model | Model |
| This model describes the Pezzey-Anderies extension to the Brander-Taylor Easter Island model. In addition to the parameters in the Brandor-Taylor model, Pezzey and Anderies have introduced $tax$ and $h_m$. Pezzey and Anderies (2003) gives the following overview: "We extend the Brander–Taylor model of population and resource development in an isolated society by adding a resource subsistence requirement to people's preferences. This improves plausibility; amplifies population overshoot and... | 09 Aug 2016 |
Pumpa Irrigation System | Model |
| In this case, the surface water level is modeled by a first order differential equation. There are six sections with equal area that are allocated water based on institutions that determine how long each sector receives water, and in what order. Water is allocated to a given sector by opening and closing gates along the irrigation canals. Based on these allocations, each sector maintains a crop yield depending on the amount of time that maintains their water level within the bounds of a desired... | 09 Aug 2016 |
Ranvahi forest community, Gadchiroli district, Maharashtra, India | Case |
| The Ranvahi forest community is located approximately 25 km from the town of Kurkheda in the Gadchiroli district of Maharashtra, India. 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 |
Resource Dynamics Under Harvest and Sunk Cost Effects | Model |
| This is a simple model for resource dynamics under harvest. The authors added expected effects of investment in fixed structures on the dynamics of settlement. These sunk-cost effects are not included in this simple model.The authors introduce a model of logictically regrowing resource exploited by a consumer. There is only one variable, which is level of local renewable sources. Parameters are: local renewable resources (R), settlement of humans (H), maximum growth rate (g), maximum level of... | 29 Nov 2017 |
San Pedro Fishery, Belize | Case |
| San Pedro, Belize is an island village of approximately 1,200 residents in 1979. Located off the coast of Belize in a strategic place on Ambergris Cay it is close to abundant local fishing and has easy access to nearby commercial markets (Belize city, Corozal, and Chetumal). The fishing cooperative, Caribena Cooperative Limited, was San Pedro’s official fishing organization handling capture, processing and sale of the village’s primary resource: marine produce consisting of... | 09 Aug 2016 |
Silag-Butir Irrigation System, Barrios Pacang, Silag, Butir, and Cabaruan, Ilocos Sur, Philippines | Case |
| In the case of the Silag-Butir Irrigation System, ricefields are located in the adjoining Barrios of Silag, Butir, Pacang and Cabaruan (between 1.5 km and 4 km off Santa Maria municipality) in the Ilocos Sur Province in the Philippines. The resource appropriated is water for irrigation. The system serves an area of 115 hectares cultivated by 201-500 total appropriator teams during wet season and 38 hectares during dry season. At the beginning of the period, there was a moderate shortage... | 09 Aug 2016 |
The Discrete Logistic | Model |
| The logistic is the simplest representation of population dynamics that contains a minimum level of biological realism. If we imagine a population of individuals at time t, the number of individuals in the next period (periods can range from seconds to days to decades depending on the organism) is the number of individuals now plus the number of births minus the number of deaths. If we assume in the simplest case there are no environmental constraints on births or deaths... | 09 Aug 2016 |
The Goulburn Broken Catchment irrigation system, northern Victoria, Australia | Case |
| The GB catchment covers 2.1 million hectares in the Murray-Darling Basin in Australia. Aboriginal people lived in the catchment for millennia before colonization around 1830. The upper, mountainous area of the catchment (900 000 ha) is more than 50% forested. The mid catchment (1 million ha) of riverine plains, low slopes and foothills has less than 20% of native vegetation cover remaining, which is highly fragmented, and the rest is used for dryland cropping and grazing. The Shepparton... | 09 Aug 2016 |
