Historical forest common property regime, Slovakia, central Europe

Case
The forestry sector has traditionally been a strong resort in most of Central European countries, as the forest covers approximately 30 – 40 % of the their territories. The management of forest resources is characterized by existence of a long forestry tradition, and dynamic evolution of the forest ownership structure originated in 17th century. These systems have been experiencing a range of disturbances, including change of political regimes, economic conditions and environmental changes that...

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...

The Hohokam Cultural Sequence (Irrigation and Foraging), Sonoran Desert, greater Phoenix basin, Arizona, USA

Case
The Hohokam is a Native American cilivilization that emerged and occupied the present day Phoenix Basin area and its outer bounds for a thousand years. The archeological records indicate that the Hohokam society evolved into a complex irrigation society and reached its peak in levels of population, social institutions, and irrigation infrastructure by the 11th century.Perplexingly though, the Hohokam society subsequently declined and collapsed by the mid 14th century. As they declined, the...

Agave Cultivation in the Arid Pre-Hispanic, Villanueva Municipality, state of Zacatecas, northern Mexico

Case
Agave is a perennial plant that can be used for multiple purposes: as edible materials for yielding caloric values and as fiber materials for producing items like clothing, ropes, and baskets. Historical records indicate that the cultivation of agave was a common practice in pre-Hispanic Northern Mexico and the American Southwest. It is generally accepted among archeologists that the agave cultivation was linked to the strategy of ensuring food supply when maize cropping failed from droughts....

The Alaskan Pollock Fishery, Bering Sea, USA

Case
The Alaskan Pollock fishery has been described as a management success, largery attributed to the adoption of ITQs, with allocations to catchers, processers, and to Alaskan communities.  The processor-fisher relationship seems key to the current success at reducing effort in the fishery. Quota is split among catcher-vessels (45%), catcher processer vessels (36%), motherships (9%), and community development quota groups (10%). There is a much smaller number of boats fishing than before...

Tanowong Bwasao Irrigation II, Philippines

Case
This paper is an update on a prior case study about the Bwasao irrigation system (Case Nos. 38 and 39) analyzing Albert S. Bacdayan’s 1980 case study on the Tanowong people of three distinct villages in the northern Philippines. For purposes of this report, the SES study boundaries were expanded to include the entire Cordillera region in the northern Philippines.  Case Summary:  Since the Tanowong people built the Bwasao irrigation canal in 1954 to accommodate the villages’ growing...

Gageo-do (Kagodo) myok grounds II, South Korea

Case
This case is an update on a prior case study about the Kagodo myok (seaweed) grounds (Case No. 86) analyzing Sang-Bok Han’s 1972 Ph.D. dissertation on field work conducted in three South Korean fishing communities from 1968 to 1972.  For purposes of this report, the SES study boundaries were expanded to include the entire South Korean coastal area and the fishery resources surrounding the peninsula extending 200 nautical miles to the east, south, and west.  Update prepared by Ute...

Pumpa Irrigation System, Central region, Nepal

Case
The Pumpa Irrigation System draws water from the Pumpa river to serve approximately 120 households.  It is a "north-south" system and is in an area with relatively steep terrain.  This case was analyzed using a stylized dynamic model to assess its capacity to cope with new challenges from global change.  The model suggested that the adaptive water allocation rules used by the community (sequential, 12 and 24 hour rotations) could significanty enhance the robustness of the system to increased...

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....

Robustness and Resilience across Scales: Migration and Resource Degradation in the Prehistoric U.S. Southwest

Case
Migration is arguably one of the most important processes that link ecological and social systems across scales. Humans (and other organisms) tend to move in pursuit of better resources (both social and environmental). Such mobility may serve as a coping mechanism for short-term local-scale dilemmas and as a means of distributing organisms in relation to resources. Movement also may be viewed as a shift to a larger scale; that is, while it may solve short-term local problems, it may...

Regime shifts in a socio-ecological model of farmland abandonment

Case
Figueiredo & Pereira (2011) developed a mathematical model with two-way linked socio-ecological dynamics to study farmland abandonment and to understand the regimes shifts of this socio-ecological system. The model considers that migration is a collective behavior socio-economically driven and that the ecosystem is dynamic. The model identifies equilibria that vary from mass migration, farmland abandonment, and forest regeneration, to no migration and forest eradication; partial migration...

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...

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...

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 "...
