The Irrigation System is located in the village Dhabi Kalan, Haryana, India at 100 miles northwest of India. The resource appropriated related to the social dilemma is water for irrigation that flows through a canal to a command area. The original cases were reported in 1980 by two authors. One author (Vander Velde 1980) argues that the irrigation system has benefited the dominant caste, Jat, more than other poorer castes in Dhabi Kalan. Another researcher, Reidinger (1980), suggests that uncertainty in water supply has limited the effectiveness of water use by farmers. The action situation involves approximately 1600 farmers of three different casts.
This case study is part of the original Common-Pool Resource (CPR) database. A summary of the original CPR coding conducted in the 1980s by Edella Schlager and Shui Yan Tang at Indiana University may be found under the CPR tab in the Institutional Analysis section below.
The resource appropriated from Chawk 16000L Dhabi Minor Irrigation is water for irrigation. This irrigation system consists of watercourses that deliver water from an irrigation canal to a command area (chak).
SCREENER:
Case: Chawk 16000L Dhabi Minor Irrigation, India
The information regarding the following common-pool resource system was taken from empirical evidence from a field setting. Data on the system was extracted from a chapter in a book. Currently, there are no additional documents to cite which may provide further information about this common-pool resource.
These documents describe one resource in detail. The primary resource is the Chawk 16000L Dhabi Minor Irrigation, situated in Dhabi Kalan of India. More generally, it is located in Middle East & South Asia. The system's sector is that of water. Relatively good information has been collected about the stakes of participants who appropriate from Chawk 16000L Dhabi Minor Irrigation. The condition of this resource is well understood. Complete information is not available regarding the strategies used by key groups interacting with the system. There is thorough documentation of the operational rules for this resource. This is the result of a high level of confidence that the authors who recorded the features of Chawk 16000L Dhabi Minor Irrigation have a complete knowledge of its particulars. Furthermore, the authors have provided sufficient data to formulate a structured coding process.
There are 51-100 total appropriator teams appropriating from the resource . At the beginning of the period discussed by the authors, there was an extreme shortage of biological and physical resources withdrawn compared to the number of units available. Appropriator teams for the resource are always formally organized.
Chawk 16000L is a command area of the Dhabi Minor Canal in the Bhakra System. The command area is located in the village, Dhabi Kalan. Vander Velde (1980, 1971) argues that the irrigation system has benefited the dominant caste, Jat, more than other poorer castes in Dhabi Kalan. Reidinger (1980) suggests that uncertainty in water supply has limited the effectiveness of water use by farmers in the Bhakra System.

OPERATIONAL LEVEL:
TYPE OF SITUATION
The processes described in the related documents are primarily related to appropriation, distribution, and production. The formal owner(s) of the resource discussed in this study is a regional government. The set of individuals who have rights to withdraw from this resource is well-defined. As of the beginning of this period, the owners are exercising (or attempting to exercise de jure) and effective in gaining closed access to this resource. Since the beginning of this period, the appropriators are not exercising, or attempting to exercise closed access to this resource.
EVENTS MARKING THE BEGINNING ACTION SITUATION
It is estimated that the operational level coded on this form ended in 1967. The estimated duration of the patterns that are described in this form is 1 to 10 years. Throughout the duration there were no changes made in operational, collective, or consititutional rules. There was no change in resource size or structure. There was no new technology introduced to the system over the duration of the patterns coded on this form. There was no substantial external change in the value of the units appropriated. The quantity of units available did not change due to a change in appropriation patterns of other appropriators' withdrawals from the same production or distribution resource. There were no new groups starting to withdraw units from the appropriation resource. There was no recorded change to one or more variables internal to the operational level. The variables that changed were -2. The author begins the description of this case at this point in history. The author begins at this point in history because The Dhabi Minor began operation in 1960-1961..

The relatively worst off appropriators have been cut out of their benefits from this resource or substantially harmed (inferred). By the end of the period studied the distance between those who were the least advantaged and those who were the most advantaged could be characterized as increasing over time (inferred).
AUTHOR'S EVALUATION AND CAUSAL ASSUMPTIONS
In this coding form the author does not focus on the readers' concept of results and the evaluation of results (inferred).
The system has not done well in predictability, certainty, and control of water supply to cultivators (Reidinger, 1980); nor has it done well in benefiting the poor (Vander Velde, 1980).The system may benefit from better coordination among rotation cycles at various levels of the system; freedom to trade water among farmers; and landholding patterns The author evaluated this system to be of low efficiency based on whether water was used in the most productive way. The author also proposed increasing efficiency by allowing water trading among cultivators.. The author discusses withdrawals per unit of effort based on -1
SUBGROUP:
Participants:
The criteria for who is a member is well defined (inferred). Membership at the start of this group numbered 60 (educated guess). This group ended with a membership of 60 (educated guess).
The following statements characterize the composition of this subgroup's population with respect to variables that may affect the capacity to communicate effectively:
The difference in composition with regard to gender identification does not affect communication (educated guess). Difference in composition with regard to ethnic or cultural identification does not affect communication (educated guess). The difference in composition with regard to clan identification does not affect communication (educated guess). The difference in composition with regard to racial identification does not affect communication (educated guess). Caste identification causes small differences in composition and mild communication problems (educated guess). Most members of this subgroup are of the cast Jats, 50% of the population. The difference in composition with regard to religious identification does not affect communication (educated guess). There is no difference in composition with regard to languages spoken (inferred).
.
Legal Rights:
Members of this subgroup have de jure rights of access (inferred). The right to withdraw is held by this subgroup de jure (inferred). Rights to participate in management of this resource are not held either de facto nor de jure (educated guess). Exlusion from use of the entire resource is not exercised either de facto nor de jure (educated guess). Members of this subgroup cannot exercise the right to decide who can be excluded from particular zones within the resource either de facto nor de jure. (educated guess). The separable right of transfer to the flow of units from this resource is not held either by de jure nor de facto (inferred). The separable rights to exercise transfer to shares of this appropriation resource, or closely related production and/or distribution resources are neither held de jure nor de facto (inferred). Transferring shares of major appropriation equipment which are necessary to engage in appropriation is not exercised either je jure nor de facto## Unknown column: EQUIPSHAR ##.
Stakes and Resources:
The length of time this subgroup has regularly appropriated from this resource is 1 through 10 years (inferred). Around 91%-100% of members reside in or adjacent to this resource (confident). The proportion of this subgroup that currently appropriates similar units from other resources is less than 10% (ambiguous). Given the economy of the location, the average annual family income (including all non-monetary forms of income) is considered average (educated guess). The variance of the average annual family income across families is high (inferred). Over time the variance of the average annual family income across families is moderate (educated guess). Capital is owned by 26%-50% of this subgroup (educated guess). No real alternatives for the supply unit are available (educated guess).
Potential Actions and Levels of Control:
A noticeable impact on the balance of the quantity of units withdrawn and the number of units available in this resource would occur in a drastic reduction of this subgroup's appropriation activities (inferred). Keeping in mind the physically available levels of withdrawal that are possible from this resource, the following shows the extent to which rules concerning different aspects of withdrawal constrain appropriation: technological rules lightly constrain (educated guess), time limits which limit the range of choice heavily constrain (inferred), quantity limits which limit the range of choice heavily constrain (inferred), and marginal units or units obtained by increasing levels of appropriation have a high value immediate return (inferred).
Technology:
The appropriative power of the technology used threatens the balance between units withdrawn and units available even if no new users are added (inferred).
Strategies Adopted:
At the beginning of the period the rate of unit withdrawals was increasing (educated guess). At the end of the period the rate of unit withdrawals was constant (educated guess). In irrigation, appropriation resources (at the beginning of the period) produce mostly grains other than paddy rice, and also sugar cane or beets, and a non-listed product. In irrigation, the appropriation resources (at the end of the period) produce mainly grains other than paddy rice, and also sugar cane or beets, and a non-listed product. During this time period members have not invested resources, such as their own labor, in maintaining or improving the structure of the appropriation resource (educated guess). Investment into constructing or improving production or distribution works for maintaining or improving their resource has not been made by members (inferred). Members do not have access to an alternative source of supply (educated guess). In characterizing the usual behavior of the members of this subgroup with respect to local operation level rules-in-use (other than in extreme shortage), it can be said that most of the members follow the rules (educated guess). No action has been proposed to alter the operational or collective-choice rules affecting the appropriation from this resource (inferred).
Subgroup Results:
This subgroup appropriates 91%-100% of its total appropriated units at the end of this period (confident). By the end of this time period the appropriates from this resource have remained approximately constant (inferred). The absolute quantity of appropriation units obtained by this group has remained constant (inferred).
The resource appropriated from Chawk 16000L Dhabi Minor Irrigation is water for irrigation. This irrigation system consists of watercourses that deliver water from an irrigation canal to a command area (chak).
OPERATIONAL RULES:
Concerning national collective choice relating to the resource, there is a national level of government, but it does not exercise jurisdiction in relation to the type of resource appropriated by this subgroup. Concerning regional collective choice, the author provides a few detailed references to operational level rules as devised by regional collective choice mechanism which have been coded below..
With regard to local collective choice, there is a local level of government or organization of appropriators, but it does not exercise jurisdiction in relation to the type of resource appropriated by this subgroup.
Boundary Rules
The following rules define the requirements that must be met before individuals are eligible to harvest or withdraw units from the appropriation resource.
The national and local level(s) of government or organization had no jurisdiction over the resource.
A rule exists requiring ownership or leasing of land in the location of the resource. This rule is enforced at the regional and rules-in-use level(s).
Entry rights may be transmitted to anyone designated by the original owner.
Within one generation of potential resource appropriators, entry rights can be given, leased, rented, sold or transferred to others.
When transfer on a temporary or permanent basis is allowed, the person who makes the transfer determines to whom such rights can be transferred.

Resource Users
Resource Users (RU)
The original case study included about 1,600 farmers.
Public Infrastructure Providers
Public Infrastructure Providers (PIP)
The irrigation system was designed to service a larger area than the water supplies could support. Due to the over-zealous design, annual water deliveries stooped to levels as low as 56% of what was promised and designated. Water allowances were predetermined and fixed regardless of environmental variation, location, and differences.
Public Infrastructure
The hard public infrastructure includes the irrigation system and canals.
The soft public infrastructure includes cropland use via 4 types of sharecropping.
Relationship 1
(RS => RU)
Soft infrastructure: Understanding of the canal water flow and those areas closer to the canal outlet have a more reliable supply.
Hard infrastructure: Irrigation system and farm supply inputs.
Relationship 2
Relationship 2
(RU => PIP)
The water supply delivered only suits a small percentage of the chak (cultivable area within the command area) farmer’s needs.
Relationship 3
(PIP => PI)
The Irrigation Department is in charge of the water distribution and irrigation system.
Relationship 4
(PI => RS)
Soft and hard human-made infrastructure drives the storage and flow of water through the irrigation and canal system.
Relationship 5
(PI => RU)
Water is fed into the irrigation system based on rainfall. There are no infrastructures to deal with conflicts between the farmers.
(RU => PI)
Farmers who are located closer to the canals have a more secure water supply.
Relationship 6
(PI => RU)
The Irrigation Department maintains the canals.
(RU => PI)
Farmers are not required to maintain the irrigation system.
Exogenous Drivers 7 (Resource System)
Annual, seasonal, and monthly rainfall variations impact the water quantity, thus the water supply is uncertain. Additionally, there is a high rate of evapotranspiration in the region.
Exogenous Drivers 7 (Public Infrastructure)
Water losses via seepage because the channels that go through the sandy and highly permeable soils are unlined and leak.
