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
More than 179,000 fields scored. 44,100 of them fall below the 50% efficiency threshold and can be found on a map. District benchmarks were delivered to the regional water authorities.
