SCREENER:

Case: Mauraro 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 Mauraro Irrigation, situated in The barrio of Mauraro 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 Mauraro 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 Mauraro Irrigation have a complete knowledge of its particulars. Furthermore, the authors have provided sufficient data to formulate a structured coding process.

There are 25-50 total appropriator teams appropriating from the resource . Appropriator teams for the resource are always formally organized.

In the Mauraro Irrigation System, nobody in particular is responsible for the allocation and distribution of water. Each farmer looks after his own water needs and acts accordingly. As there are no institutionalized or formal managers of the system, the cleaning and repair of the system's structures are the responsibility of each and every farmer. But the farmer is responsible only for the parts of the system on or bordering his farms and not for the entire system. Slight deterioration occurs in the dam and parts of the canal. Conflicts arise among farmers regarding the sharing of water from the system.

RESOURCE:

The resource appropriated from Mauraro Irrigation is water for irrigation. This irrigation resource consists of a canal that delivers water from the Alasahas Creek to farmlands.

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 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 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 51 to 75 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 dam was first built 60 years ago.

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 a moderate 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 a moderate 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: 150000 (highly 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 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 relatively high (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 experiencing some deterioration due to insufficient maintenance (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 modest levels of mutual trust (e.g. oral promises are used but appropriators may be uncertain about performance) (educated guess). ## 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 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 not records of the withdrawals from this resource kept in a systematic way (inferred). There are not records of the physical factors which directly affected the resource kept in a systematic way (inferred). There are not records of the appropriators' contributions to monitoring of the resource kept in a systematic way (inferred). There are not records of the appropriators' contribution to the maintenance of the resource kept in a systematic way (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 Infrequently/Irregularly (educated guess). The appropriators have a considerable familiarity with the characteristics of this resource (educated guess).

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). There does not appear to be an insurance mechanism available to the appropriators related to variability of income from the resource (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 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). 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 51 through 75 years (confident). Around 91%-100% of members reside in or adjacent to this resource (confident). Most people in this subgroup are slightly dependent (i.e. a small part 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 (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 moderate (educated guess). 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:

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 limit rules cause unknown contraints, quantity rules cause unknown contraints, 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 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 increasing (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 (inferred). Investment into constructing or improving production or distribution works for maintaining or improving their resource has been made by members (inferred). Resources have not been expended (including time) to avoid actions that would harm the structure of the appropriation resource (highly confident). The maintenance or improvement work is neither dependent nor contingent on the quantity of units appropriated (inferred). Members do not have access to an alternative source of supply (educated guess). 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 investment or maintenance (inferred). 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 about half 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). Attempting to alter the behavior of appropriators, members of this group have threatened or actually used violence to obtain a more favorable situation (regardless of the rules).

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 become larger (inferred).

RESOURCE:

The resource appropriated from Mauraro Irrigation is water for irrigation. This irrigation resource consists of a canal that delivers water from the Alasahas Creek to farmlands.

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, 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, regional, 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 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.

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, regional, and local level(s) of government or organization had no jurisdiction over the resource.

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:

There is a rule requiring regular maintanence labor input based on location. This rule is enforced at the 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 hired labor. Most of the time, each worker works independently.

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. Incarceration is not imposed as penalty on appropriators for breaking rules related to the appropriation of this resource. No 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 cannot obtain external aid to develop their appropriation technologies. Appropriators can obtain aid from a national (private or public) agency(s) to develop or repair their production, distribution, or appropriation resources. Appropriators cannot obtain external aid to develop technologies for using the resource units. 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.
