SCREENER:

Case: Tanowong Bwasao 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 journal article. Currently, there are no additional documents to cite which may provide further information about this common-pool resource.

These documents describe two resources in detail. The primary resource is the Tanowong Bwasao Irrigation, situated in The Tanowong villages 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 Tanowong Bwasao 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 Tanowong Bwasao Irrigation have a complete knowledge of its particulars. Furthermore, the authors have provided sufficient data to formulate a structured coding process.

The Tanowong Bwasao Irrigation covers an unknown area. 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of the period discussed by the authors, there was an apparently balanced supply of biological and physical resources withdrawn compared to the number of units available.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.

Before 1954, the Tanowong people relied on water from two streams (about 4km away) to irrigate their rice fields. As the water supply became inadequate to meet their cultivation needs, they decided in 1954 to dig a 25km long ditch to divert water from a new source, the Bwasao Stream, to their fields. Since the project was completed, Tanowong have enjoyed adequate water for cultivation. The Tanowong's exclusive right to get water from the Bwasao stream was challenged by another community, but the Tanowong have been successful in upholding their exclusive right to the water source.

RESOURCE INFO:

The resource appropriated from Tanowong Bwasao Irrigation is water for irrigation. It is produced physically and is a renewable moving (fugitive) unit. The irrigation system studied includes a network of ditches that deliver water to farmlands.

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, 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).

The study did not indicate whether or not there are strategic points within the resource where the main flow of the water for irrigation can be controlled. 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 not considerable variation in the flow of water for irrigation within a single year (educated guess). 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 is steeply sloping (educated guess).

The boundaries of the production resource and the boundaries of the appropriation resource overlap partially, but they are not equivalent. (highly confident). The boundaries of the production resource are totally seperated from the boundaries of the location (confident). The boundaries of the distribution resource are not identical to the boundaries of the appropriation resource. The distribution 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 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).

RESOURCE:

The resource appropriated from Tanowong Bwasao Irrigation is water for irrigation. The irrigation system studied includes a network of ditches that deliver water 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 1972. The estimated duration of the patterns that are described in this form is 11 to 25 years. Throughout the duration there were no changes made in operational, collective, or consititutional rules. There was a planned change in resource size and 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 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 apparently balanced (inferred). 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 (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 apparently balanced (inferred). 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 (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:

*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 relatively low (educated guess). 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 appropriation resource was moderately well maintained, and in good working order (educated guess).

At the beginning of this period the appropriators shared moderate to high levels of mutual trust (e.g. oral promises given high credence) (inferred). 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 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 was no information in the study about whether or not there are records of the withdrawals from this resource kept in a systematic way. 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' contributions to monitoring of 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 (highly confident). 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 (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). 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 exist (inferred). Differences between subgroups relating to clan identification does not affect communication (educated guess). Differences between subgroups relating to racial identification does not exist (inferred). Differences between subgroups relating to caste identification does not exist (inferred). Differences between subgroups relating to religious identification does not exist (inferred). 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 that the appropriators have a general cultural pattern that stressed various types of cooperative activities besides the management of this resource (educated guess). 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). It is unlikely that local appropriators would attempt to bribe an official if an official monitor or guard moved 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). There was a general estimate of 101-200 appropriators at the end of the period (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 (educated guess). Official monitors are paid in commodities. Almost all of the monitors were full-time (inferred).

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: 63.1 - 0 - 0 - 0

EVALUATION OF RESULTS

There are no appropriators who were consistently disadvantaged in this period (educated guess). 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's results indicate that the water supply was adequate, and that the irrigators were able to secure water rights to the production resource. These results are due to the irrigators' ability to mobilize manpower to establish a new source of water; and irrigators' ability to interact with government officials. The concept of the results was not completely captured.

The criteria for who is a member is well defined (inferred). Membership at the start of this group numbered 200 (inferred). This group ended with a membership of 200 (inferred).

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). Most members of this subgroup are ethnically identified as Bontoc. 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). Religious identification causes no difference in composition (inferred). 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 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 11 through 25 years. 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). 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). Over time the variance in average annual family income is low (inferred). Capital is owned by 91%-100% of this subgroup (confident). No real alternatives for the supply unit are available (confident).

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 lightly constrain (educated guess), time limit rules cause unknown contraints, 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 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 increasing (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 (highly confident). Resources have been expended (including time) to avoid actions that would harm the structure of the appropriation resource (inferred). Members do not 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 (inferred). 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).

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 (educated guess). The absolute quantity of appropriation units obtained by this group has remained constant (educated guess).

RESOURCE:

The resource appropriated from Tanowong Bwasao Irrigation is water for irrigation. The irrigation system studied includes a network of ditches that deliver water 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, a level of government or organization of appropriators exists at the location and the author provides a few detailed references 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 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 2 cycle(s).

Authority Rules:

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

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 rule is in effect during dry seasons.

There is a rule permitting 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 a less restrictive, regularly adopted/used set of rules. The rule is in effect during rainy seasons.

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 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.

There is a rule requiring emergency repair labor 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.

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, labor force is organized in relatively small teams.

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. 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. Severe community shunning is used for an unstated duration of time 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.
