Description
The resource appropriated from the Chancay-Lambayeque Basin is water for irrigation. There are two groups of farmers. One groups is located upstream the main canal of the system, and the second groups downstream. Upstream users are freeriding from the canal: They do not pay for the infrastructure maintenance, and at the same time they appropriate water without any formal regulation. Downstream farmers are members of an irrigation association and follow their rules. The national water law supports these rules. The author reported many fights around water use, thus this case is considered as an unsuccessful instance of common-pool resource management.

Relationship 1
Appropriation Rules: Water appropriation for downstream farmers depends on the crop they grow and of the size of their landholding. At a national level there is a consensus of irrigation coefficients for each crop and the Irrigation District will deliver water considering those coefficients
Relationship 2
Downstream Farmers elect and ca be elected to form the Irrigation Association
Relationship 3
Public Infrastructure Providers have regular meetings to determine water tariffs and water allocation.
ALA and PEOT work together to supervise the hard infrastructure condition and to control that the irrigation association is allocating water accordingly to their agreements.
ALA is in charged of providing license to farmers to allow them to appropriate water from the canal.
ANA supervise ALA
The irrigation association have the right to access, withdraw and to manage water resources.
Relationship 4
The Tinajones reservoir collects water from the Chancay River and from rain.
Water is delivered through the Taymi canal. The condition of this canal affects water availability (and loss).
Relationship 5
Rules are enforced within downstream users but not within downstream users.
Relationship 6
Users should pay for the infrastructure. In practice only downstream users pay.
