SCREENER:

Case: Cadchog 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 Cadchog Irrigation, situated in Bontoc Poblacion 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 Cadchog Irrigation. 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 Cadchog Irrigation 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 . 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of the period discussed by the authors, there was an apparently balanced supply of biological and physical resources withdrawn compared to the number of units available.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 irrigation system can generally provide enough water to the appropriators. There is no formal organization to manage this system, although two women have beeen appointed as leaders. There are rules governing water allocation and maintenance.

RESOURCE INFO:

The resource appropriated from Cadchog Irrigation is water for irrigation. It is produced physically and is a renewable moving (fugitive) unit. The irrigation system focused on in the following study is comprised of canals that deliver water from the nearby Sang-ngan creek.

The boundary of this resource has natural/constructed attributes which do not limit entry. The boundaries of this resource are smaller than the location, and exist in one country, and are not divided among multiple 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). The case study did not include information regarding whether or not there is considerable variation over space in the availability of Water for irrigation within the resource. There is considerable, and predictable variation in the flow of Water for irrigation within a single year (highly confident). The case study did not include information regarding whether or not there is considerable variation in the flow of Water for irrigation from year to year.

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 (inferred). 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).

LOCATION:

The appropriation resources are situated in Bontoc poblacion. The boundaries of the location are the boundaries of a village. The appropriation resource present in this location consists of canals delivering irrigation water.

The system is located within one country. Within this country, the system's location is not divided among several general purpose local jurisdictions at the same level. A permanent population lives year round in this location (highly confident). There is frequent contact and communication between people in this location and officials in a nearby administrative center (inferred).

The resource appropriated from Cadchog Irrigation is water for irrigation. The irrigation system focused on in the following study is comprised of canals that deliver water from the nearby Sang-ngan creek.

OPERATIONAL LEVEL:

TYPE OF SITUATION

The processes described in the related documents are primarily related to appropriation, production, distribution and use. 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 1980. The estimated duration of the patterns that are described in this form is 1 to 10 years. Throughout the duration there was change made primarily by the appropriators 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 author begins the description of this case at this point in history. The author begins at this point in history because In 1975, the appropriators elected two women to supervise their group work.

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 apparently balanced (highly confident). 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 (highly confident). 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 apparently balanced (highly confident). 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 (highly confident).

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 beginning of the period: 30000 (confident)

Square meters of fields irrigated at the end of the period: 30000 (confident)

*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 passable (educated guess). 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 were no problems of pollution in this or other resources, due to the way units are being appropriated (inferred). 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 quite low (inferred).

INFORMATION LEVELS

There is no information in the study to indicate the availability of maps or charts of the appropration resource for use by the appropriators. Maps and/or charts of the production and distribution resources are not documented as being available, or unavailable in this case study. 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 usually records of the withdrawals from this resource kept in a systematic way (educated guess). There are usually records of the physical factors which directly affected the resource kept in a systematic way (educated guess). There are usually records of the appropriators' contributions to monitoring of the resource kept in a systematic way (educated guess). There are always records of the appropriators' contribution to the maintenance of the resource kept in a systematic way (educated guess). Records are not kept in a language accessible to most of the appropriators (educated guess). The keepers of these records are not "officials" (educated guess). These records are not available for inspection by appropriators (educated guess). There are arenas being used for the exchange of information about conditions of the resource (ambiguous). Appropriators get together to discuss mutual problems of the resource at a frequency which was not included in the case study. The appropriators have an intimate knowledge of the characteristics of this resource (ambiguous).

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 (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) (inferred). 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.

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). If someone violated the rules-in-use related to the appropriation process from this resource, it is likely 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 likely as not 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).

POSITIONS AND PARTICIPANTS

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).

SUBGROUP:

This appropriation group are the farmers who withdraw water from the canal system. The criteria for who is a member is well defined. Membership at the start of this group numbered 200 (confident). This group ended with a membership of 200 (highly confident).

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 (inferred). The difference in composition with regard to clan identification does not affect communication (educated guess). Racial identification causes no difference in composition (inferred). Caste identification causes no difference in composition (inferred). 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 (ambiguous). The right to withdraw is held by this subgroup de jure (ambiguous). Rights to participate in management of this resource is held de jure (ambiguous). Exclusion from use of the entire resource is exercised de jure (ambiguous). 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). 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:

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 less than 10% (ambiguous). 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 cause unknown contraints, time limits which limit the range of choice lightly constrain (educated guess), quantity limits which limit the range of choice lightly constrain (educated guess), and marginal units or units obtained by increasing levels of appropriation have a moderate value immediate return (educated guess).

Technology:

The appropriative power of the technology used does not threaten the balance between units withdrawn and units available even if no new users are added (educated guess).

Strategies Adopted:

At the beginning of the period the rate of unit withdrawals was constant (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 paddy rice. In irrigation, the appropriation resources (at the end of the period) produce mainly paddy rice. 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). The maintenance or improvement work is neither dependent nor contingent on the quantity of units appropriated (educated guess). 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 (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 (confident).

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).

RESOURCE:

The resource appropriated from Cadchog Irrigation is water for irrigation. The irrigation system focused on in the following study is comprised of canals that deliver water from the nearby Sang-ngan creek.
