The resource appropriated is water for irrigation, and the system is comprised of a network of canals that divert water from the Canayon Creek to farms situated in three barrios of the municipality of Santa Cruz in Ilocos Sur, Philippines: Calaoaan, Villa Laurencia, and Gabor. There are 51-100 total appropriator teams appropriating from the resource who are always formally organized. The system is used to cultivate rice during the wet season from July to December. During the dry season, the canal dries up and farmers shift to grow tobacco by water drawn from open wells.
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: Calaoaan Irrigation, Philippines
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 Calaoaan Irrigation, situated in Sta Cruz municipality of Philippines. More generally, it is located in Orient. The system's sector is that of water. Relatively good information has been collected about the stakes of participants who appropriate from Calaoaan 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 Calaoaan Irrigation have a complete knowledge of its particulars. Furthermore, the authors have provided sufficient data to formulate a structured coding process.

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 exercising nor attempting to exercise closed 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 1978. The estimated duration of the patterns that are described in this form is 26 to 50 years. Throughout the duration there were no changes made in operational, collective, or consititutional rules. There was a planned change in resource structure only. 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 does not begin the description of this case at this point in history.
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 apparently balanced (educated guess). 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 apparently balanced (educated guess).
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: 1500000
*In fisheries and other biological systems, this is the maximum sustainable number of units. In irrigation, this refers to the optimal water requirements of the crops in the established fields served by this system.
At the beginning of the period, the units were predominantly used to produce other units.
At the end of the period, the units were predominantly used to produce other units.
As of the beginning of the period, the quality of the units being withdrawn from the resource was not included in the study. As of the end of the period, the quality of the units being withdrawn from the resource was passable (educated guess). At the beginning of the period of the study, there was no information provided regarding whether or not there are problems of pollution in this or other resources, due to the way units are being appropriated. At the end of the period of the study, there were no problems of pollution in this or other resources due to the way units are being appropriated (ambiguous). As of the beginning of the period, the extent of technical externalities resulting from the appropriation activities of participants from this resource was not indicated. As of the end of the period, the extent of technical externalities resulting from the appropriation activities of participants from this resource was relatively low (educated guess). 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 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 moderately well maintained, and in good working order (educated guess). 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 (inferred).
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 appropriation resource do not differ from the production and distribution resource (ambiguous). 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 are not records of the appropriators' contributions to monitoring of the resource kept in a systematic way (inferred). There are always records of the appropriators' contribution to the maintenance of the resource kept in a systematic way (highly confident). Records are kept in a language accessible to most of the appropriators (inferred). The keepers of these records are officials at some level (highly confident). These records are available for inspection by appropriators (inferred). 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 (inferred). The appropriators have an intimate knowledge of the characteristics of this resource (inferred).
POTENTIAL ACTIONS AND LEVELS OF CONTROL
There are appropriators and non-appropriators that made up a specialized staff or workers to undertake maintenance (educated guess). The quality or quantity of the units available to the appropriators are not documented as having experienced any effect of past appropriators. 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). The study does not indicate whether or not there was an insurance mechanism available to the appropriators related to variability of income from the resource.
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 exist (ambiguous). Differences between subgroups relating to clan identification does not affect communication (educated guess). Differences between subgroups relating to racial identification does not exist (ambiguous). Differences between subgroups relating to caste identification does not exist (ambiguous). Differences between subgroups relating to religious identification does not affect communication (educated guess). Differences between subgroups relating to languages spoken does not exist (ambiguous). Differences between subgroups relating to general cultural views of the resource system and its use does not exist (ambiguous). Differences between subgroups relating to any problems that affect communication does not exist (ambiguous).
The general manner in which appropriators related to one another during this study is a relatively neutral, quid-pro-quo manner -- each exchange was evaluated for what it might bring (ambiguous). If someone violated the rules-in-use related to the appropriation process from this resource, it is likely as not that he/she would encounter social sanctions imposed by other appropriators (who are not filling posititions as official monitors) (educated guess). If someone violates the rules-in-use related to the appropriation process from this resource, it is unlikely that he/she would encounter physical sanctions by other appropriators (who are not filling posititions as official monitors) (educated guess). If someone violates the rules-in-use related to the appropriation process from this resource, it is likely as not that an official monitor or guard would move to impose sanctions (educated guess). There is a considerable range of sanctions imposed depending on rule infractions and in regard to social, physical, and official sanctions (inferred).
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 some undocumented number appropriators. There was a general estimate of 51-100 appropriators at the end of the period (highly confident). The "official" position of monitor (apart from the willingness of all appropriators to monitor) does exist, and appropriators (not necessarily all) rotated into this position (highly confident).
The general estimate for the number of official monitors on duty at one time during peak hours was 6-10 (inferred). None of the monitors were full-time (highly 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: 26.1 - 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).

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). Ethnic or cultural identification causes no difference in composition (ambiguous). The difference in composition with regard to clan identification does not affect communication (educated guess). Racial identification causes no difference in composition (ambiguous). Caste identification causes no difference in composition (ambiguous). The difference in composition with regard to religious identification does not affect communication (educated guess).

.
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 (educated guess). 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). 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 (highly confident). Around 91%-100% of members reside in or adjacent to this resource (confident). Most people in this subgroup are moderately dependent (i.e. about half of the family income) on this resource (inferred). Around 91%-100% of this subgroup work a substantial amount of time in activities not associated with appropriation from this resource (confident). The proportion of this subgroup that currently appropriates similar units from other resources is 91%-100% (confident). Given the economy of the location, the average annual family income (including all non-monetary forms of income) is considered average (educated guess). Over time the variance in average annual family income is low (ambiguous). Alternatives for the supply unit are available at a moderate cost (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 cause unknown contraints, time limits which limit the range of choice moderately 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 (ambiguous).
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 coffee, teas, cocoa, tabacco, spices, or d. 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 (inferred). Resources have been expended (including time) to avoid actions that would harm the structure of the appropriation resource (ambiguous). Members have access to an alternative source of supply (inferred). Members of this group have not increased their use of alternative sources of supply of this unit (educated guess). 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).
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 (educated guess).
The resource appropriated from Calaoaan Irrigation is water for irrigation. The resource of interest in this study is comprised of a network of canals that divert water from the Canayon Creek to farms situated in three barrios - Calaoaan, Villa Laurencia, and Gabor.
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, there is a regional level of government, but it does not exercise jurisdiction in relation to the type of resource appropriated by this subgroup.
With regard to local collective choice, a level of government or organization of appropriators exists at the location and the author provides relatively full information about operational level rules as devised by collective choice mechanisms which have been coded below.
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 regional level(s) of government or organization had no jurisdiction over the resource.
A rule exists requiring membership in an organization. This rule is enforced at the local and rules-in-use level(s).
A rule exists requiring ownership or leasing of land in the location of the resource. This rule is enforced at the local and rules-in-use level(s).
Authority and Scope Rules
The default conditions for both authority and scope rules do not apply.
The following paragraphs include information on rules of 1 cycle(s).
Authority Rules:
The national and regional level(s) of government or organization had no jurisdiction over the resource.
There is a rule requiring withdrawal at a fixed time slot, based on location. This rule is enforced at the local and rules-in-use level(s), and is part of the most restrictive, regularly adopted/used set of rules.
The length of the withdrawing season is 0 week(s)..
There is a rule forbidding withdrawal whenever and wherever desired, based on unspecific criteria. This rule is enforced at the local and rules-in-use level(s), and is part of the most restrictive, regularly adopted/used set of rules.
The authority and scope rules do not apply to whether or not certain subgroups received substantially unequal privileges, because there is only one subgroup.
Scope Rules:
The national and regional level(s) of government or organization had no jurisdiction over the resource.
There is a rule requiring regular maintanence labor input based on equal division among all appropriators or teams of appropriators. This rule is enforced at the local and rules-in-use level(s), and is part of the most restrictive, regularly adopted/used set of rules.
There is a rule requiring emergency repair labor based on equal division among all appropriators or teams of appropriators. This rule is enforced at the local and rules-in-use level(s), and is part of the most restrictive, regularly adopted/used set of rules.
There is a rule requiring labor, money, or materials to be used for major capital investment, however, the basis criteria for this rule was not included in the case information. This rule is enforced at the local and rules-in-use level(s), and is part of the most restrictive, regularly adopted/used set of rules.
If labor input for maintenance is required, the input can be substituted by some payment (e.g. money, materials). Most of the time, the entire labor force works as a team.
Information Rules
There exists a rule requiring recording of maintenance work done by appropriators. This rule is enforced at the local and rules-in-use level(s).
This information was recorded by an AGO.
Payoff Rules
The default condition, that all appropriators can retain whatever they can physically keep hold of and no external rewards, taxes, or sanctions are imposed is not imposed in this case. The authors have the following confidence level for the results of this section: inferred. Moderate fines can be imposed on appropriators for breaking rules related to the appropriation of this resource. Appropriators may not lose their entry or appropriation rights for breaking rules related to the appropriation of the resource. Appropriators can obtain aid from a national (private or public) agency(s) to develop or repair their production, distribution, or appropriation resources. Appropriators are not party to price support contracts or guaranteed purchase agreements for the selling of resource units or commodities produced by resource units.
The following percentages indicate the percentages assigned to individual positions. If more than one percentage is listed per position, the individual percentages refer to the different arrangements existing within the operational rules.
Aggregation Rules
The default condition, that no rules specify contraints or requirements on the process to be used in deciding which actions will be taken, and that appropriators can have as much independence in deciding upon actions as they are physically able to exert, is imposed in this case.
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.
