The situation
Regional water authorities allocate by plan and report by plan. Nobody could say which districts were genuinely losing water and which were simply under-reporting it.
What we did
We derived actual evapotranspiration per parcel and set it against applied water, producing a water productivity index for every field, then rolled the results up into district-level benchmarks.
What it produced
All 43,354 fields scored across 876,558 hectares, at an average water efficiency of 77%, with the weakest districts identified on a map. District benchmarks were delivered to the regional water authority.
