The resource appropriated from Sananeri Tank is water for irrigation. The resource discussed in this study includes a tank and the channels that divert water to the field. The author shows that nonformal local cultivators associations make an important contribution to the overall performance of the irrigation system, even where government agencies are formally responsible for irrigation. Such organizations mobilize local resources in various tasks, including inspection and repair of physical structures, acquisition and distribution of tank water, and interaction with government bureaucracies on tank-related issues. Leaders of the organization are accountable directly to the cultivators, and are neither created nor controlled by a government agency.
An update analysis of the Sananeri Tank case was made in 2013 by Chai Ying, visiting scholar at Arizona State University. From the standpoint of social-ecological systems analysis, this case was originally a success in terms of water user association ability to deal with a potential commons dilemma. Formal follow-up research about this case absent, so there is no way to address any further information on the commons dilemma.
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.

SCREENER:
Case: Sananeri Tank, 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 paper issued by a scholar or research institution. Currently, there are 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 Sananeri Tank, situated in Sananeri 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 Sananeri Tank. The condition of this resource is well understood. Complete information is 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 Sananeri Tank have a complete knowledge of its particulars. Furthermore, the authors have provided sufficient data to formulate a structured coding process.
There are 101-200 total appropriator teams appropriating from the resource . Appropriator teams for the resource are always formally organized.
Meinzen-Dick's study is based upon field research of a small-scale irrigation tank in Tirunelveli District, Tamil Nadu. She shows that nonformal local cultivators' associations make an important contribution to the overall performance of the irrigation system, even where government agencies are formally responsible for irrigation. Such organizations mobilize local resources in various tasks, including inspection and repair of physical structures, acquisition and distribution of tank water, and interaction with government bureaucracies on tank-related issues. Leaders of the organization are accountable directly to the cultivators, and are neither created nor controlled by a government agency.

LOCATION:
The appropriation resources are situated in Sananeri Tank and the field irrigated by its water. The boundaries of the location are natural. The appropriation resource present in this location consists of Sananeri Tank and the channels that direct water to the fields (coding). There is also a groundwater table that supplies water through private wells; Sananeri Tank which provides silt for brick manufacture; trees along the foreshore; tank bed for grazing sheep, goats, and cattle; tank provides standing water for bathing, watering animals and raising fish. Regarding the use of the irrigation system, there were conflictual effects throughout the entire period in the relationships among appropriation processes.
The system is located within one country. A permanent population does not live year round in this location . There is frequent contact and communication between people in this location and officials in a nearby administrative center . This location is also characterized by an economy that is stable and tied to other economic networks during the entire time period (ambiguous).

OPERATIONAL LEVEL:
TYPE OF SITUATION
The processes described in the related documents are primarily related to appropriation, distribution, and production. 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 not indicated as either attempting, or failing to attempt to exercise access to this resource. Since the beginning of this period, the appropriators are exercising (or attempting to exercise de jure) effective closed access to this resource.
EVENTS MARKING THE BEGINNING ACTION SITUATION
It is estimated that the operational level coded on this form ended in 1982. The estimated duration of the patterns that are described in this form is 26 to 50 years. Throughout the duration there was no indication in this study as to whether or not there are major changes in operational, collective, or consititutional rules. There was no information provided in this study to indicate whether or not there are any changes in the size and/or structure of the resource. There was no indication in this study which indicated whether or not new technology was introduced to the resource during the time of coding. There was no information included in the study to indicate whether or not there was a substantial external change in the value of the units appropriated. The quantity of units available did not have documentation regarding changes due to the appropriation patterns of other appropriators' withdrawals from the same production or distribution resource. There was no information in this study indicating whether or not there were any new groups starting to withdraw units from the appropriation resource. There was no information included in the study to indicate whether or not there was a recorded change to one or more variables internal to the operational level. The author begins the description of this case at this point in history. The author begins at this point in history because The tank has existed at least since 1800. The institutional environment of the tank must have undertaken changes since the independence of India..
CONDITIONS AT THE BEGINNING AND END OF PERIOD COVERED BY THIS FORM*
For biological resources at the beginning of this period, the balance between the quantity of units withdrawn and the number of units available was not included in the case information. For biological resources at the end of this period, the balance between the quantity of units withdrawn and the number of units available was an extreme shortage (inferred). For physical resources at the beginning of this period, the balance between the quantity of units withdrawn and the quantity of units needed, given the usual patterns of use for these units was not included in the case information. For physical resources at the end of the period the balance between the quantity of units withdrawn and the quantity of units needed, given the usual patterns of use for these units, was an extreme shortage (inferred).
The following includes the available statistics on the use of this resource at the beginning of the time period, followed by the end of the time period:
Square meters of fields irrigated at the end of the period: 1738400

At the beginning of this study, the interference between the appropriation technology for this resource and the appropriation processes for other resources in this location was not recorded in the case information. At the end of this study, the interference between the appropriation technology for this resource and the appropriation processes for other resources in this location was moderate (inferred). At the beginning of this study the appropriation resource was being maintained at a level that was not recorded in the case information. At the end of this study the appropriation resource was well maintained, and in excellent working order (inferred). At the beginning of this period the appropriators shared levels of trust that are not indicated in the case study. At the end of the period the appropriators shared moderate to high levels of mutual trust (e.g. oral promises given high credence) (inferred). ## Unknown markup: Start ##By the end of this period no change had occurred in the property rights regime related to the appropriation resource.
INFORMATION LEVELS
There are readily available maps or charts of the appropriation resource for use by the appropriators (ambiguous). Maps and/or charts of the production and distribution resources are available to appropriators (educated guess). The appropriators of this resource can be seen by each other while withdrawing units from the resource (educated guess). No appropriators are in radio communication with each other while appropriating from the resource (educated guess). There are actions being taken, by appropriators or officials, to generate information about the condition of the resource (inferred). There are not records of the withdrawals from this resource kept in a systematic way (ambiguous). There was no information in the study about whether or not there are records of the physical factors which directly affected the resource kept in a systematic way. There was no information in the study about whether or not there are records of the appropriators' contribution to the maintenance of the resource kept in a systematic way. There is no information in the study to indicate whether or not records are kept in a language accessible to most of the appropriators. The keepers of these records are not indicated as being "officials" or "non-officials" in this case study. The case study did not indicate whether or not these records are available for inspection by appropriators. There are arenas being used for the exchange of information about conditions of the resource (inferred). Appropriators get together to discuss mutual problems of the resource weekly (educated guess). The appropriators have an intimate knowledge of the characteristics of this resource (inferred).
POTENTIAL ACTIONS AND LEVELS OF CONTROL
There are non-appropriators that made up a specialized staff or workers to undertake maintenance (inferred). The quality or quantity of the units available to the appropriators are not adversely affected by the strategies of prior appropriators (educated guess). There are not problems of pollution resulting from activities of others who are not appropriators of this resource or inhabitants of this location (e.g. acid rain, sewage disposal) (educated guess). There does not appear to be an insurance mechanism available to the appropriators related to variability of income from the resource (educated guess).
PATTERNS OF INTERACTION
Differences between subgroups relating to gender identification does not affect communication (educated guess). Differences between subgroups relating to ethnic identification does not affect communication (educated guess). Differences between subgroups relating to clan identification does not affect communication (educated guess).

Differences between subgroups relating to languages spoken does not exist (inferred). Differences between subgroups relating to general cultural views of the resource system and its use does not exist (inferred). Differences between subgroups relating to any problems that affect communication does not exist (inferred).
The general manner in which appropriators related to one another during this study is a relatively positive, reciprocal manner -- the presumption was made that long-term relationships are involved and positive actions are undertaken without a specific expectation of return (educated guess). The documents present evidence of specific types of cooperative activities between the appropriators related primarily to other local resources (inferred). If someone violates the rules-in-use related to the appropriation process from this resource, it is likely that an official monitor or guard would move to impose sanctions (educated guess).
POSITIONS AND PARTICIPANTS
At the end of the period studied there was no information coded to indicate whether or not the position of non-appropriator (individuals prevented from using the resource) existed. At the beginning of the period there was a general estimate of 101-200 appropriators (educated guess). The "official" position of monitor (apart from the willingness of all appropriators to monitor) does exist, and appropriators are selected by one another for this position (inferred).
The general estimate for the number of official monitors on duty at one time during peak hours was 6-10 (inferred). Official monitors are paid in commodities. None of the monitors were full-time (confident).
NUMBER AND RELATIONSHIPS AMONG SUBGROUPS
There will be 1 subgroup form(s) completed in relation to this operational level form. The ID number(s) of the subgroup(s) coded are as follows: 11.1 - 0 - 0 - 0
EVALUATION OF RESULTS
The study did not indicate whether or not there are appropriators who were consistently disadvantaged in this period. The relatively worst off appropriators have not been cut out of their benefits from this resource or substantially harmed (educated guess). 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 remaining relatively constant over time (educated guess).
AUTHOR'S EVALUATION AND CAUSAL ASSUMPTIONS
In this coding form the author focuses on the readers' concept of results and the evaluation of results (inferred).
The author recorded an increase of water supply from the main system, a reliable distribution of water, reduction in conflict, better maintenance, and greater local control. Ayacut assoc. did well in all these aspects. This was likely due to the personal integrity of officials, mechanisms to hold officials acccountable (those who receive water should be ones that pay acquisition & distribution costs(p.77)), and a somewhat even distribution of landholdings(p.94). Comments recorded regarding evidence that is presented concerning the nature and level of transaction costs are as follows: The nature and level of the transaction costs are associated with different water allocation rules and the amount of money per hectare irrigators spend in irrigation management. The transaction costs are high.
SUBGROUP:
Participants:
The criteria for who is a member is well defined (inferred). Membership at the start of this group numbered 150. This group ended with a membership of 150.
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). Racial identification causes no difference in composition (inferred). The difference in composition of the group with regard to caste does not affect communication (educated guess). Most members of this subgroup are of the cast Vellalas. The difference in composition with regard to religious identification does not affect communication (educated guess). Most members of this subgroup are religiously identified as Hindu, Muslim, and Christian. 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 is held de facto (inferred). Exclusion from use of the entire resource is exercised de jure (inferred). 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 26 through 50 years (educated guess). Around 91%-100% of members reside in or adjacent to this resource (educated guess). Most people in this subgroup are very dependent (i.e. most of the family income) on this resource (inferred). The proportion of this subgroup that currently appropriates similar units from other resources is 51%-75% (educated guess). 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 moderate (educated guess). Over time the variance in average annual family income is low (inferred). Capital is owned by 76%-90% of this subgroup (educated guess). Alternatives for the supply unit are available at a moderate cost (inferred).
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 cause unknown contraints, time limits which limit the range of choice lightly constrain (educated guess), quantity limits which limit the range of choice moderately constrain (educated guess), 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 end of the period the rate of unit withdrawals was constant (educated guess). In irrigation, the appropriation resources (at the end of the period) produce mainly paddy rice, and also legumes, edible tree crops, and non-tree fruits and vegetables. During this time period members have invested resources, such as their own labor, in maintaining or improving the structure of the appropriation resource (highly confident). Investment into constructing or improving production or distribution works for maintaining or improving their resource has been made by members (highly confident). Resources have been expended (including time) to avoid actions that would harm the structure of the appropriation resource (ambiguous). The maintenance or improvement work is either dependent or contingent on the quantity of units appropriated (inferred). Members have access to an alternative source of supply (highly confident). Members of this group have increased their use of alternative sources of supply of this unit (highly confident). At least one member has assumed entrepreneurial activity in trying to achieve coordinated strategies in relationship to both withdrawal and investment (highly confident). 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 almost all of the members follow the rules set in place (inferred). The level of infraction of members who are not rule followers is generally small (inferred). Action in both the collective choice arena and constitutional-choice arena has been proposed to alter the operational or collective-choice rules affecting the appropriation from this resource (educated guess).
Subgroup Results:
This subgroup appropriates 91%-100% of its total appropriated units at the end of this period (highly confident). By the end of this time period the appropriates from this resource have remained approximately constant (highly confident). The absolute quantity of appropriation units obtained by this group has remained constant (inferred).
The resource appropriated from Sananeri Tank is water for irrigation. The resource discussed in this study includes a tank and the channels that divert water to the field.

Aggregation Rules
Overall Questions About Rules Configuration
The general framework of the rules-in-use has governed the activities of this subgroup for 26 to 50 years.
Sananeri Tank
Resource System
Key shared resource: water
Resource Users
Cultivators using water for irrigated crops
Public Infrastructure Providers
- A government agency, the Public Works Department (PWD), is responsible for water allocation to the tank and O&M of the physical structures.
- Sananeri Ayacut Association is responsible for acquisition and distribution of tank water, monitoring and minor repair works on the tank, and resolving conflicts among the local cultivators.
Public Infrastructure
- Key natural infrastructure is watershed and land.
- Key human-made hard infrastructure: Tank, sluices and feeder channels.
- Key human-made soft infrastructure:
(1) As a general rule of appropriation, head-end tanks are given priority for receiving water during dry periods. When water in the tank is too low, the sluice gates are left open for the cultivators to draw water from the tank on an individual basis.
(2) Water use requires ownership of ayacut land plus an annual payment to the government and to the ayacut association.
Relationship 1
Cultivators employ a variety of soft human, and hard human-made infrastructures to extract water for irrigation. Tank water is the first choice for cultivators to use and well water is the supplement. When there is not enough tank water for the whole ayacut, cultivators turn to private wells for irrigation.
Relationship 2
- The core committee members of the Sananeri Ayacut Association are elected by the cultivators themselves based on their trust in each other.
- The association selects its president and secretary from the elected core committee members of the association. The association also selects neeranis (water acquisition managers) and neerpachis (water distribution managers).
- Through the association, cultivators participate in crafting rules and enforcing them. The cultivators can discharge the committee members, neeranis, and neerpachis for unsatisfactory performance.
- Cultivators must contribute towards paying the neeranis and neerpachis for their services.
- The association president provides information on local conditions to the PWD officials through petitions and field visits.
Relationship 3
- The under provision of the Sananeri tank repairs by the PWD (once every three years) urges the association president to petition its engineer for more service.
- Maintenance of tank, its feeder channels, and the anicut structure is handled by the neeranis and neerpachis.
- Neeranis and neerpachis monitor against water theft.
- The cultivators clean the channels crossing their fields.
Relationship 4
Controls the stock and flow of water in the system
Relationship 5
- Water allocation to the tank and the fields is done depending on the time of the year (dry period and rainy season).
Relationship 6
- Collective choice rules compel the resource users to clean the channels and monitor against water theft. They ensure good access to the resource.
