The case of Kheri Irrigation takes place in Sonjo village of Kheri and its adjacent farmlands within the Ngorongoro district of the Arusah region in Tanzania. The resource appropriated is water flowing from a stream, three springs, furrows, and sluices that supply water for irrigation and domestic uses. The boundaries of the location are defined by the village settlement and the land owned by the village people. There are a total of 101-200 formally organized appropriator teams.
After Gray's (1963) ethnography of the Sonjo, Potkanski and Adams (1998) conducted a study in same villages. They found that the population growth have led to more intensely contested boundaries and satellite villages attempt to gain access to irrigation water. Water is also less scarce due to government programs (related to structural adjustments programs) attempting to increase the production of water intensive cash crops. Given these disturbances, the local water managers attempted to allocate water use based on a pay-per-use system. This was deemed as unfair by central government, and a Village Chairman was appointed to ensure equitable allocation of water. This decreased the legitimacy of the local water managers, and increased crop failures as scarce water was spread over a larger area of land. Water managers were less able to stop water theft during this time. At the end of the study, the authors state that the traditional system was reinstated to restore a sense of order in the governance system.
This case 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 Kheri Irrigation is water. The following study discusses an irrigation system that consists of a furrow and sluices that divert water from a stream and three springs to the adjacent farmland.

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 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 Kheri Irrigation, situated in Kheri Village of Tanzania. More generally, it is located in Africa. The system's sector is that of water. Relatively good information has been collected about the stakes of participants who appropriate from Kheri 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 Kheri 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 . Appropriator teams for the resource are always formally organized.
Gray spent six months in 1955 with the Sonjo, primarily in the village of Kheri. In his discussion of Kheri's irrigation practices he uses Karl Wittfogel's hypotheses about irrigation as the guiding framework, and finds that "Wittfogel's main thesis finds little support from Sonjo data. ...Among the traditional societies of Africa ... despotism is a characteristic that seems to vary independently of the practice of irrigation."

RESOURCE:
The resource appropriated from Kheri Irrigation is water. The following study discusses an irrigation system that consists of a furrow and sluices that divert water from a stream and three springs to the adjacent 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 1955. The estimated duration of the patterns that are described in this form is 76 to 100 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 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 not included in the case information. For biological resources at the end of this period, the balance between the quantity of units withdrawn and the number of units available was apparently balanced (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 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 end of the period: 2600000
*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, and also consumed by appropriators and families.
At the end of the period, the units were predominantly used to produce other units, and also consumed by appropriators and families.
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 low (educated guess). At the beginning of this study, the interference between the appropriation technology for this resource and the appropriation processes for other resources in this location was not recorded in the case information. 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 well maintained, and in excellent working order (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 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 (highly confident).
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 (inferred). 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 are not records of the physical factors which directly affected the resource kept in a systematic way (ambiguous). There are not records of the appropriators' contributions to monitoring of the resource kept in a systematic way (ambiguous). There are not records of the appropriators' contribution to the maintenance of the resource kept in a systematic way (ambiguous). 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 daily (highly confident). 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 (highly confident). 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) (highly confident). The study does not indicate whether or not there was an insurance mechanism available to the appropriators related to variability of income from the resource.
PATTERNS OF INTERACTION
Differences between subgroups relating to gender identification does not affect communication (educated guess). Differences between subgroups relating to ethnic identification does not 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 (inferred). 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 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 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 moderate range of sanctions imposed depending on rule infractions and in regard to social, physical, and official sanctions (inferred). 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 (highly confident). At the beginning of the period there was a general estimate of some undocumented number appropriators. There was a general estimate of 101-200 appropriators at the end of the period (confident). The "official" position of monitor (apart from the willingness of all appropriators to monitor) does exist, and appropriators (not necessarily all) rotated into this position (highly confident). This position monitors rules devised by local collective choice processes (column 3 of the rules form) and rules-in-use.
The appropriators monitor the appropriation activities of each other apart from the monitoring of any "official" guards (highly confident). The general estimate for the number of official monitors on duty at one time during peak hours was 11-25 (highly confident). Official monitors are paid in commodities and in money. None of the monitors were full-time (highly confident).

Subgroups 9.1 and 10.1 do not differ in levels of dependency on the units withdrawn from this resource and use of the appropriation units.
EVALUATION OF RESULTS
There are appropriators who were consistently disadvantaged in this period. The study did not indicate whether or not the relatively worst off appropriators have or have not been cut out of their benefits from this resource or substantially harmed. 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 does not focus on the readers' concept of results and the evaluation of results.
SUBGROUP:
Participants:
This appropriation group are the Wenamiji. They are a group of councilmen who held primary rights and authority regarding the irrigation system. The criteria for who is a member is well defined (highly confident). Membership at the start of this group numbered 17 (ambiguous). This group ended with a membership of 17 (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:
Gender identification causes no difference in composition (inferred). Ethnic or cultural identification causes no difference in composition (inferred). Most members of this subgroup are ethnically identified as Sonjo. The difference in composition with regard to clan identification does not affect communication (educated guess). The clan identification for most of this subgroup is Almost equally distributed among th four clans. 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 (highly confident). The right to withdraw is held by this subgroup de jure (highly confident). Rights to participate in management of this resource is held de jure (highly confident). Exclusion from use of the entire resource is exercised de jure (highly confident). 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. (ambiguous). The separable right of transfer to the flow of units from this resource is held de jure by this subgroup (highly confident). 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. 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 high (educated guess). The variance of the average annual family income across families is low (inferred). Over time the variance in average annual family income is low (inferred). Capital is owned by 91%-100% of this subgroup (educated guess). No real alternatives for the supply unit are available (educated guess).
Potential Actions and Levels of Control:
Considering that there are multiple subgroups using this resource, most of the appropriators withdraw units where the flow of units first enters into the resource (i.e. headenders) (inferred). 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 (ambiguous). 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 (inferred), quantity limits which limit the range of choice lightly constrain (inferred), 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 end of the period the rate of unit withdrawals was constant (educated guess). In irrigation, the appropriation resources (at the end of the period) produce mainly legumes, and also grains other than 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 (inferred). 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 (highly confident). In characterizing the usual behavior of the members of this subgroup with respect to local operation level rules-in-use (other than in extreme shortage), it can be said that 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 (educated guess). The absolute quantity of appropriation units obtained by this group has remained constant (educated guess).

Legal Rights:
Members of this subgroup have de jure rights of access (highly confident). The right to withdraw is held by this subgroup de jure (highly confident). Rights to participate in management of this resource are not held either de facto nor de jure (inferred). Exlusion from use of the entire resource is not exercised either de facto nor 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 held de jure by this subgroup (highly confident). 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. 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 high (educated guess). The variance of the average annual family income across families is low (inferred). Over time the variance in average annual family income is low (inferred). Capital is owned by 91%-100% of this subgroup (educated guess). No real alternatives for the supply unit are available (educated guess).
Potential Actions and Levels of Control:
Considering that there are multiple subgroups using this resource, most of the appropriators withdraw units after one or more other subgroups have withdrawn (inferred). 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 (ambiguous). 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 (inferred), quantity limits which limit the range of choice lightly constrain (inferred), 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 end of the period the rate of unit withdrawals was constant (educated guess). In irrigation, the appropriation resources (at the end of the period) produce mainly legumes, and also grains other than 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 (inferred). 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). 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). No action has been proposed to alter the operational or collective-choice rules affecting the appropriation from this resource (inferred).

The resource appropriated from Kheri Irrigation is water. The following study discusses an irrigation system that consists of a furrow and sluices that divert water from a stream and three springs to the adjacent 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 1955. The estimated duration of the patterns that are described in this form is 76 to 100 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 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 not included in the case information. For biological resources at the end of this period, the balance between the quantity of units withdrawn and the number of units available was apparently balanced (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 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 end of the period: 2600000
*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, and also consumed by appropriators and families.
At the end of the period, the units were predominantly used to produce other units, and also consumed by appropriators and families.
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 low (educated guess). At the beginning of this study, the interference between the appropriation technology for this resource and the appropriation processes for other resources in this location was not recorded in the case information. 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 well maintained, and in excellent working order (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 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 (highly confident).
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 (inferred). 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 are not records of the physical factors which directly affected the resource kept in a systematic way (ambiguous). There are not records of the appropriators' contributions to monitoring of the resource kept in a systematic way (ambiguous). There are not records of the appropriators' contribution to the maintenance of the resource kept in a systematic way (ambiguous). 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 daily (highly confident). 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 (highly confident). 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) (highly confident). The study does not indicate whether or not there was an insurance mechanism available to the appropriators related to variability of income from the resource.
PATTERNS OF INTERACTION
Differences between subgroups relating to gender identification does not affect communication (educated guess). Differences between subgroups relating to ethnic identification does not 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 (inferred). 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 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 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 moderate range of sanctions imposed depending on rule infractions and in regard to social, physical, and official sanctions (inferred). 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 (highly confident). At the beginning of the period there was a general estimate of some undocumented number appropriators. There was a general estimate of 101-200 appropriators at the end of the period (confident). The "official" position of monitor (apart from the willingness of all appropriators to monitor) does exist, and appropriators (not necessarily all) rotated into this position (highly confident). This position monitors rules devised by local collective choice processes (column 3 of the rules form) and rules-in-use.
The appropriators monitor the appropriation activities of each other apart from the monitoring of any "official" guards (highly confident). The general estimate for the number of official monitors on duty at one time during peak hours was 11-25 (highly confident). Official monitors are paid in commodities and in money. None of the monitors were full-time (highly confident).

EVALUATION OF RESULTS
There are appropriators who were consistently disadvantaged in this period. The study did not indicate whether or not the relatively worst off appropriators have or have not been cut out of their benefits from this resource or substantially harmed.

Capital is owned by 91%-100% of this subgroup (educated guess). No real alternatives for the supply unit are available (educated guess).
Potential Actions and Levels of Control:
Considering that there are multiple subgroups using this resource, most of the appropriators withdraw units after one or more other subgroups have withdrawn (inferred). 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 (ambiguous). 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 (inferred), quantity limits which limit the range of choice lightly constrain (inferred), 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 end of the period the rate of unit withdrawals was constant (educated guess). In irrigation, the appropriation resources (at the end of the period) produce mainly legumes, and also grains other than 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 (inferred). 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). 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). No action has been proposed to alter the operational or collective-choice rules affecting the appropriation from this resource (inferred).
Subgroup Results:

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.

Entry rights may be transmitted to one or more members of within a family.
Within one generation of potential resource appropriators, entry rights can be transferred to members of a family but not outside the family.
When transfer on a temporary or permanent basis is allowed, the person who makes the transfer determines to whom such rights can be transferred.

Rules for allocation of irrigation water during times of scarcity
Relationship 1
Occasional scarcity
Relationship 2
wenamiji make decisions of management while others can voice their opinions
Relationship 3
managed by wenamiji and wakiama. Repairs and mainteanance is done by farmers and the warrior class (young adults)
Relationship 4
Some water loss in canals - efficiency maintained by irrigating fields by blocks.

Increased population of farmers
Public Infrastructure Providers
From wenamiji managed to a joint management system. The wenamiji are given the task of ensuring orderly use of irrigation water, while an appointed District Chairman ensures equitable distribution
Public Infrastructure
Same system of sluices and hill canal furrows
Relationship 1
Increasing scarcity due to higher demand. This is because of higher population and the use of more water intensive cash crops. Increased rate of water theft.
Relationship 2
Users can express their concerns to the wenamiji or the chairman. Greater state control decreased the perceived legitimacy of the wenamiji.
Relationship 3
THe wenamiji attempted to commodify water due to scarcity. The state attempted to assume greater control.
Relationship 4
Same as before
Relationship 5
Decreased perceived legitimacy of wenamiji fails to limit water theft.
Relationship 6
Same as before
Exogenous Drivers 7 (Resource System)
Less water per person available due to use of water intensive cash crops and population.
