ECO.7:4 - Solution
ECO.7:4.1 - Recover the resource and the actions that affect it
Identify the resource, the useful units or services obtained, the relevant condition and the time over which it can change. Distinguish taking a unit from providing or restoring the resource. Ask whose actions affect availability, quality or renewal, including parties outside the initial user group.
Use the physical or operating account already available. When its limits matter, obtain the required contribution from PHY, MMP or OPS. A stated allocation cannot enlarge a physical flow. Equally, a model of flow does not settle who is entitled to use it.
Determine what access, exclusion and withdrawal rights already hold. Separate those from actual control and practice. A proposed change must be adopted through the applicable arrangements; the analyst’s allocation is not itself an effective rule.
ECO.7:4.2 - Construct a workable combination of rules
Compare combinations that address the actual difficulty: who can enter, what may be used and when, who contributes to upkeep, how consequential use and condition become visible, how disagreements are resolved and who can change the arrangement. Existing suitable rules can be retained; this is not a requirement to invent a complete code.
Test whether contributions and benefits give participants a feasible reason and ability to comply. Check the costs of observation and response, including the burden on smaller participants. Make a response to a violation proportionate to its effect and the available interpretation; a missing observation can be a measurement problem rather than proof of abuse.
Relate local arrangements to wider effects. Several communities may share a catchment or infrastructure; their local allocations need a way to handle the common constraint. Provide the coordination needed for that common constraint, retaining legitimate local decisions.
ECO.7:4.3 - Test ordinary use and changed conditions
Run a concrete allocation and renewal case through the proposed rules. Include a plausible change such as low supply, new entry, a failure to contribute or a disputed reading. Determine who detects the change and which decision can adapt the arrangement.
Return the feasible arrangement, a limited trial or the unresolved constraint. A few measurements that discriminate the choices can be enough; a complete social survey is not automatically required. Revisit physical conditions, access and rule effects when their change invalidates the arrangement.
