The Na Pae Irrigation System is located in the village of Ban Pae Luang, Chiang Mai Province, Thailand. The resource appropriated related to the social dilemma is water for irrigation diverted through canals from Mae Pae River. The original case was reported in 1983 and catalogues an action situation involving 80 members. At the beginning of the period discussed by the authors, there was a balanced supply of biological and physical resources withdrawn compared to the number of units available
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.
The resource appropriated from Na Pae Irrigation is Water for irrigation. The irrigation system described here includes canals that deliver water from Mae Pae River to some nearby farmland.
SCREENER:
Case: Na Pae Irrigation, Thailand
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 thesis or dissertation. 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 Na Pae Irrigation, situated in Ban Pae Luang of Thailand. 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 Na Pae 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 Na Pae Irrigation 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of the period discussed by the authors, there was an apparently balanced supply of biological and physical resources withdrawn compared to the number of units available.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.
Tan-Kim-Yong compares two traditional irrigation communities in Northern Thailand. An upland irrigation system (Na Pae) serves 80 members and requires only 2 or 3 days of work by all the members for maintenance every year. The organization of the system is led by two elected officials. Rules are minimal and simple. This upland irrigation system is contrasted with a lowland system (Muang Mai) which serves 600 members and requires more extensive maintenance activities. The organization of the system is more complex. Rules are more elaborate.

The resource appropriated from Na Pae Irrigation is Water for irrigation. It is produced physically and is a renewable moving (fugitive) unit. The irrigation system described here includes canals that deliver water from Mae Pae River to some nearby farmland.
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, 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). There is not considerable variation over space in the availability of Water for irrigation within the resource (educated guess). There is considerable, and mildly 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 is steeply sloping (confident).
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 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 (inferred).
LOCATION:
The appropriation resources are situated in the village of Ban Pae Luang and its nearby farmland. The boundaries of the location are village boundaries as well as the natural layout of the fields. The appropriation resource present in this location consists of canals that deliver water from Mae Pae River to the fields (coding). A road, well, and bridge are also present. Regarding the use of the irrigation system, there were few adverse affects throughout the entire period in the relationships among appropriation processes.
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). This location is also characterized by an economy that is changing and relatively autonomous with respect to other economic networks during most of the time period (confident).
The latitude of this location is 18.20'N, and its longitude is 99.00'E. The elevation of this location is 450 meters (inferred). The highest elevation is 500 (inferred). The lowest elevation of this location is 400 (inferred). The region's average annual rainfall is 1254 milimeters (highly confident). The region's average annual evapotranspiration is 1301 milimeters. The distribution of rainfall and evapotranspiration per month is as follows:
January precipitation: 6.6, evapotraspiration: 46

COUNTRY, REGION, TIME:
This study examines a common-pool resource institution in Thailand, starting in 0, ending in 0.
During the period of time that this region was studied, the citizens of Thailand were able to follow formal procedures to create their own local general purpose governments (ambiguous). If a basic charter of a traditionally evolved local general purpose government was in existence, it could be maintained (inferred). The citizens living in Thailand were able to follow formal procedures to create their own local special purpose enterprises with some public powers (inferred). Regarding the charter of a local special purpose enterprise, the level of choice given to the citizens was not included in the case information.
During the time of this study, citizens in this or similar regions had created or evolved public enterprises with public treasuries and collective decisions outside the formal governmental structure (highly confident). The stance of the national government was not included in the case information toward efforts of the citizens to organize locally and create general or special enterprises to cope with local problems.
The individuals that made collective choice decisions in Thailand were officials appointed by a higher level government whose actions were reviewed, approved, or rejected by their superiors in some decision areas and who could act on their own in other areas (educated guess). The source of funds used by general purpose local governments was not included in the case study. The judiciary system in this region during the time of the study was a mixed system - some conflicts were resolved by traditional system and some conflicts were processed by a non-traditional system (educated guess). The judges gained their positions through ways that were not included in the case information. The tenure of the judges was not included in the case information. In general, the judges in Thailand has a reputation that was not included in the case information. The case study did not include information on whether there was a single dominant legal tradition in use in this region.
The resource appropriated from Na Pae Irrigation is Water for irrigation. The irrigation system described here includes canals that deliver water from Mae Pae River to some nearby farmland.
OPERATIONAL LEVEL:
TYPE OF SITUATION
The processes described in the related documents are primarily related to appropriation, production, distribution and use. 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 1981. 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 resource was constructed at this point in time..
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 (educated guess). 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 (educated guess). 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:
Square meters of fields irrigated at the beginning of the period: 240000 (highly confident)
Square meters of fields irrigated at the end of the period: 640000 (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 passable (educated guess). As of the end of the period, the quality of the units being withdrawn from the resource was passable (inferred). 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). As of the end of the period, the extent of technical externalities resulting from the appropriation activities of participants from this resource was quite low (inferred). At the beginning of this study the appropriation resource was well maintained, and in excellent working order (inferred). At the end of this study the appropriation resource was well maintained, and in excellent working order (inferred). 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 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 (highly confident). Appropriators get together to discuss mutual problems of the resource monthly (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 (highly confident). 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 (inferred). Differences between subgroups relating to ethnic identification does not exist (inferred). Differences between subgroups relating to clan identification does not affect communication (inferred). 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 affect communication (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 (inferred). The documents present evidence of specific types of cooperative activities between the appropriators related to other local resources, as well as evidence that the appropriators have a general cultural pattern that stressed various types of cooperative activities besides the management of this resource (confident). If someone violated the rules-in-use related to the appropriation process from this resource, it is very likely that he/she would encounter social sanctions imposed by other appropriators (who are not filling posititions as official monitors) (inferred). 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 that an official monitor or guard would move to impose sanctions (educated guess). There is a limited range of sanctions imposed depending on rule infractions and in regard to social, physical, and official 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 the position of non-appropriator (individuals prevented from using the resource) did exist (educated guess). At the beginning of the period there was a general estimate of Less than 25 appropriators (highly confident). 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 not exist (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: 51.1 - 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 appropriators have done well in regard to coordinated efforts in maintenance and allocation of water. The evaluation was based on physical conditions of the resource, organizational arrangements, and the community of appropriators. The author discusses withdrawals per unit of effort based on -2
SUBGROUP:
Participants:
The criteria for who is a member is well defined (highly confident). Membership at the start of this group numbered 17 (highly confident). This group ended with a membership of 80 (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:

Most members of this subgroup are ethnically identified as Lua. The difference in composition with regard to clan identification does not affect communication (inferred). Racial identification causes no difference in composition (inferred). Caste identification causes no difference in composition (inferred). Religious identification causes no difference in composition (inferred). Most members of this subgroup are religiously identified as Buddhism. 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. (inferred). The separable right of transfer to the flow of units from this resource is held de jure by this subgroup (inferred). 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 (inferred).
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 (highly confident). Most people in this subgroup are very dependent (i.e. most of the family income) on this resource (inferred). Less than 10% of this subgroup work a substantial amount of time in activities not associated with appropriation from this resource (inferred). 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 (inferred). 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). Capital is owned by 91%-100% of this subgroup (confident). 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 not occur in a drastic reduction of this subgroup's appropriation activities (educated guess). 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 lightly 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 low 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 (inferred). At the end of the period the rate of unit withdrawals was constant (inferred). 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, and also non-tree fruits and vegetables. 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 neither dependent nor contingent on the quantity of units appropriated (inferred). Members do not have access to an alternative source of supply (educated guess). 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 (highly confident). The level of infraction of members who are not rule followers is generally small (inferred). 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 (inferred).
The resource appropriated from Na Pae Irrigation is Water for irrigation. The irrigation system described here includes canals that deliver water from Mae Pae River to some nearby farmland.

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:
There is a rule requiring withdrawal up to a fixed percentage of the total units available during a period, based on the ownership or leasing rights to a certain proportion of the flow. 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 the dry season; the Na Pae organization manages the rotation of water between the head and the tail sections of both branches.
There is a rule requiring withdrawal up to a fixed percentage of the total units available during a period, based on the ownership or leasing rights to a certain proportion of the flow. 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 the rest of the year, when water flows continuously.
There is a rule requiring withdrawal at a fixed time slot, set annually/periodically by someone living in the 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 rule is in effect during the dry season; the Na Pae organization manages the rotation of water between the head and the tail sections of both branches.
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 rule is in effect during the dry season; the Na Pae organization manages the rotation of water between the head and the tail sections of both branches.
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 a less restrictive, regularly adopted/used set of rules. The rule is in effect during the rest of the year, when water flows continuously.
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:

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 cannot be substituted. Most of the time, the entire labor force works as a team.
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: confident. Incarceration is not imposed as penalty on appropriators for breaking rules related to the appropriation of this resource. Light 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.
