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 |
Culture and Human Agro-ecosystem Dynamics: the Tsembaga of New Guinea | Model |
| The model of Tsembaga agro-ecology explores the coupled dynamics involving population growth, renewable resource base, resource consumption by humans, and the self-regulating effect of cultural ritual. The model demonstrates that the cultural ritual of Tsembaga (Kaiko) can stabilize the Tsembaga population and its resource level. This is achieved by attenuating wildly fluctuating limit cycles of population and resource levels down to desirable small-amplitude cycles. Anderies (1998) describes... | 09 Aug 2016 |

Dhap Kulo, Dhap Village, Thamalangtar Dhap Village Panchayat, Sindhupalchok 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... | 09 Aug 2016 |

Dynamics of coupled populations in an open, three-trophic-level system | Case |
| The investigated stream system, which consists of three-coupled populations (benthic algae, grazers, and predators), is modeled as a fixed region of space(e.g., stream reach) and over a limited period of time. The time scale allows for growth of primary producers (algae), but not for reproduction of grazers and predators. The system is open, allowing immigrations and emmigrations. Immigration at all trophic levels is assumed to be governed by external factors and to be... | 09 Oct 2016 |
Dynamics of coupled populations in an open, three-trophic-level system | Model |
| This model explicitly incorporates the immigration and emigration processes in the context of three-trophic-level systems (e.g., a stream reach), and reveals how the coupled populations will change in response to the primary-productivity gradients (e.g., r, K). In contrast, traditional simple food-chain models study mostly two-trophic-level system which can be open or close. More interstingly, though not reflected here, there are two contrasting models presented in the paper:... | 09 Oct 2016 |
Ecological-economic model for optimal control of fire-driven, semi-arid rangelands | Model |
| This is an ecological-economic model that endogenizes discontinuous change between states of fire-driven, semi-arid rangelands which may exist in varying degrees as grassland and woodlands depending partly on the given soil conditions. More sandy soils will result in woodlands, whereas clay soils will more likely result in grasslands. One of the critical features of this model is the existence and impact of fires on these different types of rangelands. Grasslands may build up biomass and create... | 01 Oct 2016 |
Electromagnetic Spectrum Allocation: Wireless Networks | Case |
| Wireless network is a network set up by using radio signal frequency to communicate among computers and other network devices, due to its easy setup feature and no cabling involved, it have become an important tool in the construction of modern society. New emerging technologies allow users to perform more and more complex tasks, driving an increasing mean bandwidth consumption per user. However, a wireless network has limited capacity to provide information transactions, that is, finite... | 09 Aug 2016 |
FRG Organic Agriculture | Case |
| Organic agriculture in Germany jointly produces food and biodiversity, among others. The question of this case is how the regulation of the organic farming sector affects its expansion and level of innovation. | 11 Mar 2020 |
Furrow irrigation system of the Marakwet escarpment in Kenya | Case |

Global wildlife markets and whale conservation | Case |
| This case study coincides with a master’s thesis project conducted by Melanie Sturm in 2013-2014. It is an analysis of the relevance for wildlife markets to meet conservation objectives. Markets stand to be instrumental as more natural resources face the risk of overexploitation and/ or under-provision of proper control mechanisms and supporting infrastructure. Granted, market solutions are not a panacea, but there are settings and species for which rights-based management is appropriate, and... | 09 Aug 2016 |
Grazing, Fire, and Australian Rangeland Dynamics, New South Wales, Australia | Case |
| The ecology of savanna rangelands is the product of a dynamic interaction between grass, shrubs, fire and livestock, and a high variability in rainfall. Humans play an important role in these dynamics by raising livestock who graze, and by suppressing fire. The authors of this case explore the implications of these human activities for the resilience of the Australian rangelands, characterized by two main stable states. The first state is dominated by grasses with scattered trees and shrubs.... | 09 Aug 2016 |
