The Kaset Samakee Water User Association, Isan region, northeastern Thailand

Case
The Kaset Samkee water user association is a part of the The Lam Pra Plerng Irrigation Project, constructed by Thailand's Royal Irrigation Department (RID). RID organized four Water User Associations (WUAs) in the project area that are then divided into "chaeks" (a chaek is an area served by a common farm-turn-out). The common irrigator is paid by the RID and is responsible for arranging water distribution and maintenance schedules in the chaek. Farmers in the area of the Kaset Samkee...

The irrigation system of the northwest Murcia Region (Spain): robustness of SES to the intrusion of new resource users

Case
Farmers in the northwest Murcia Region (Spain) have used for centuries the water from springs to irrigate their lands. They are organized in irrigation communities adapted to cope with rainfall variability. This system was robust in terms of its use of the water emerging from the springs to irrigate small patches of land. In recent decades, large agrarian companies have settled in this region and use groundwater to irrigate new lands. This intrusion had led the levels of this resource to drop...

The Irrigation System of La Mancha Oriental, La Mancha Region, Albacete and Cuenca provinces, Spain

Case
The Mancha Oriental Irrigation system is one aquifer of La Mancha Region, located in Albacete and Cuenca provinces in Spain. The case study involves an analysis of the evolution of the system from 1975 to 2000. The extension of the land is 8,500km2  but only 1,000Km2   is irrigated. The authors catalogue an action situation involving users that appropriates groundwater as resource units from the Júcar Hydrographic Confederation. The original case study authors focused on institutions for...

The Irrigation System of Campo Montiel, La Mancha region, Spain

Case
Campo de Montiel Irrigation system is based on an aquifer of 2500 km2, but only that only 3% of it was used for agriculture. Campo de Montiel is located in La Mancha Region, in Spain. The case study involves an analysis of the evolution of the system from 1980 to 2000. The authors catalogue an action situation involving 29,000 total users that appropriate groundwater as the resource unit from the High Basin of Guadiana River, but only 101 farmers appropriate groundwater for irrigation purposes...

The Innovation Commons: The Nanotechnology Innovation Network, Phoenix, AZ

Case
 The nanotechnology innovation network of Metropolitan Phoenix ranks among the top thirty across US cities focused on nanotechnology development. The present case examines the structure of the innovation network, consisting of approximately 400 diverse organizations, between 2011 and 2012. The commons dilemma revolves around managing future risks and benefits from nanotechnology development; the resource is a heterogenous mix of natural and human-made infrastructures.

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...

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...
