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.
