SCREENER:

Case: Oaig-Daya Irrigation System, 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 Oaig-Daya Irrigation System, situated in Oaig-Daya 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 Oaig-Daya Irrigation System. 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 Oaig-Daya Irrigation System 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of the period discussed by the authors, there was an apparently balanced supply of biological and physical resources withdrawn compared to the number of units available. Appropriator teams for the resource are always formally organized.

The rice fields served by the Oaig-Daya irrigation system are located in the neighboring barrios of Oaig-Daya and Parioc. The system derives its water from the Oaig-Daya Creek. There are five subcanals within the system. An irrigation group called the Penned Bakir Farmers Association, which had its beginning in the 1920s, manages the system.

The resource appropriated from Oaig-Daya Irrigation System is water for irrigation. It is produced physically and is a renewable moving (fugitive) unit. The irrigation system discussed here consists of canals that deliver water from the Oaig-Daya Creek to the nearby farmlands.

The boundary of this resource has natural/constructed and institutional arrangements which do not limit entry. The boundaries of this resource are smaller than the location, and exist in one country, but are divided among several general purpose local jurisdictions at a single level. The boundaries of this resource are independent of a development project designed by non-residents.

There are not distinct and stable micro-environmental or ecological zones within this resource (educated guess).

There are strategic points within the resource where the main flow of the water for irrigation can be controlled (inferred). There is not considerable variation over space in the availability of water for irrigation within the resource (educated guess). There is considerable, and predictable variation in the flow of water for irrigation within a single year (inferred). There is not considerable variation in the flow of water for irrigation from year to year (educated guess).

The topography of the resource or the land immediately around the resource was not included in the study.

The boundaries of the production resource do not coincide with the boundaries of the appropriation resource. The production resource is a facility connected to the appropriation resource (highly confident). The boundaries of the production resource are not equivalent to the boundaries of the location, but lie within the boundaries of the location (highly confident). The boundaries of the distribution resource are roughly equivalent to the boundaries of the appropriation resource (highly confident). The boundaries of the production resource are not equivalent to the boundaries of the distribution resource. The production resource is a facility connected to the distribution resource (highly confident).

The headworks (production resource) are operated by the same agency(s) (or the same group(s) of people) as the appropriation resource, and the agency(s) or the group(s) of people are the sole operator(s) of the headworks (highly confident). The distribution system is solely operated by the same agency(s) (or the same group(s) of people) as the appropriation resource (highly confident). The distribution system is solely operated by the same agency(s) (or the same group(s) of people) as the headworks of the system (highly confident).

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 are local appropriators. 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 may be exercising or attempting to exercise closed access to this resource, however this information was not included in the study.

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 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 system came into existence in the late twenties.

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: 1000000

*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 (inferred). 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 modest (educated guess). 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 levels of trust that are not indicated in the case study. ## Unknown markup: Start ##By the end of this period no information had been recorded regarding a change in the property rights regime related to the appropriation resource. At the end of this period the owners were exercising, or attempting to exercise, de jure and effective closed access to this resource (inferred). At the end of the period the appropriators were exercising, or attempting to exercise, de jure and effective closed access to this 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 production resource 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 always records of the withdrawals from this resource kept in a systematic way (educated guess). 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 always records of the appropriators' contribution to the maintenance of the resource kept in a systematic way (educated guess). Records are kept in a language accessible to most of the appropriators (inferred). The keepers of these records are officials at some level (inferred). These records are available for inspection by appropriators (ambiguous). 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 quarterly (educated guess). The appropriators have an intimate knowledge of the characteristics of this resource (inferred).

POTENTIAL ACTIONS AND LEVELS OF CONTROL

There are no 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, because there are no prior appropriators (inferred). 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 affect communication (educated guess). Differences between subgroups relating to clan identification does not affect communication (educated guess). Differences between subgroups relating to racial identification does not affect communication (educated guess).

Differences between subgroups relating to any problems that affect communication does not affect communication (educated guess).

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 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 the position of non-appropriator (individuals prevented from using the resource) did not exist (ambiguous). 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 are selected by one another for this position (educated guess).

The general estimate for the number of official monitors on duty at one time during peak hours was 6-10 (highly confident). None of the monitors were full-time (highly confident).

NUMBER AND RELATIONSHIPS AMONG SUBGROUPS

.

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 jure (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 (educated guess). 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 (educated guess).

Stakes and Resources:

The length of time this subgroup has regularly appropriated from this resource is 26 through 50 years (confident). Around 91%-100% of members reside in or adjacent to this resource (educated guess). Most people in this subgroup are moderately dependent (i.e. about half of the family income) on this resource (educated guess). Around 91%-100% of this subgroup work a substantial amount of time in activities not associated with appropriation from this resource (educated guess). The proportion of this subgroup that currently appropriates similar units from other resources is less than 10% (inferred). 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 low (inferred). Over time the variance in average annual family income is low (inferred). No real alternatives for the supply unit are available (educated guess).

Potential Actions and Levels of Control:

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 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 (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 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 (highly confident). Resources have been expended (including time) to avoid actions that would harm the structure of the appropriation resource (inferred). The maintenance or improvement work is either dependent or contingent on the quantity of units appropriated (highly confident). Members do not have access to an alternative source of supply (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 most of the members follow the rules (educated guess). The level of infraction of members who are not rule followers is generally medium (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 (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).

RESOURCE:

The resource appropriated from Oaig-Daya Irrigation System is water for irrigation. The irrigation system discussed here consists of canals that deliver water from the Oaig-Daya Creek to the nearby farmlands.

Information Rules

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 temporarily lose their entry or appropriation rights for breaking rules related to the appropriation of the resource. Severe community shunning is used temporarily as a sanction that is consciously imposed on appropriators who break rules related to the appropriation of this 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.
