ECO-SHARED - Preserve access under a changed shared constraint

• Situation: Several local groups have workable allocations, but their combined use now threatens the resource or excludes other legitimate users.
• Question: Which shared constraint and coordination relation must their local arrangements retain?
• First useful result or blocker: A feasible allocation with an effective adaptation route, or the incompatibility that remains.
• Start with: Use ECO.7 to connect withdrawal, renewal and access. Use ECO.8 when the local arrangements need a wider coordination relation. Use ECO.9 to compare preserving, modifying and replacing the rules through the practices and capabilities each alternative needs.

For example, a lower canal inflow can invalidate the previous daily allowances. Correct arithmetic for each group’s old allocation does not answer the joint constraint. The receiving result is a physically possible allocation with an effective way to adopt and adapt it, or a clearly identified incompatibility.

Now suppose the physical supply recovers, but a new digital access procedure excludes users who cannot operate it. The next contribution is access, assistance or a different procedure; another water calculation would miss the failure. HCD and MDPE can help obtain the needed capability and practice. A digital inscription of the rule does not provide them.

• Stop or return: Close the requested allocation or rule question when its conditions are sufficient. Return a new physical, access or capability failure to its actual contributor.
