Understanding Agriculture Water Productivity
How we calculate. Water productivity = yield ÷ water used. See our methodology and accuracy policy .
Real-world scenario: A typical Agriculture Water Productivity case uses crop yield (or production) 4000 and water used 500. Enter the same figures below to reproduce the worked path.
What is Agriculture Water Productivity?
A crop-per-drop KPI. Distinct from irrigation efficiency (used÷applied) and Environmental water intensity.
- Same boundary
- Water > 0
- Label ET vs applied
The Formula
Worked Example
Common Use Cases
- Homework: irrigation agronomy
- Farm: season WP
- Study: pair with irrigation efficiency
Pro Tips
- Don’t swap Environmental intensity
- State water definition
- Match yield basis
Limitations: Agriculture Water Productivity results are educational agriculture and farm-planning aids—not agronomic prescriptions, pesticide labels, veterinary advice, or legal compliance. Confirm units and recommendations with your extension service, agronomist, or instructor.
Common mistakes
- Swapping part and whole: The denominator must be the full total, not a subset.
- Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
- Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
